Discovering Cats<br />

My wife has been adopted. It came as<br />

rather a surprise, but the whole family<br />

is delighted. There’s a lot of truth in the<br />

saying that cats choose their hosts, rather<br />

than the other way around, as with other<br />

pets. The interesting thing is that my wife<br />

didn’t actually want a pet at the moment,<br />

and certainly not a cat, after having been<br />

bitten as a child.<br />

It came about when our next-door<br />

neighbours moved and the new catloving<br />

neighbours accepted an additional<br />

responsibility. During the upheaval we had<br />

a visitor, who was looking for a peaceful<br />

corner. As we stroked her and gave her a<br />

little snack, as you do, she decided to stay<br />

for a while. My wife found the purring and<br />

stroking very peaceful herself and one<br />

thing led to another. During our vacation<br />

we spent a lot of time in the garden, the<br />

three of us, and found it very relaxing.<br />

As a child I lived on a farm, so I knew<br />

more about working dogs, as well as<br />

cows, geese and horses before starting<br />

this magazine. Cats were there to catch<br />

mice. Since this summer I have learned<br />

more about domestic cats. “Our“ cat<br />

(who prefers not to be named to keep<br />

her reputation intact) does give a lot of<br />

love, it’s true. She also looks for food,<br />

water, snacks and a bed for the day-time<br />

rests. She is also aware of her territory and<br />

defends it fiercely. This mostly happens<br />

at dawn or dusk and is loudest when we<br />

have just gone to sleep.<br />

The new neighbours (and official owners<br />

of the cat) report that she comes to eat<br />

and socialise every day, but they are<br />

happy if she is sharing herself around. We<br />

have spent time discovering what the pet<br />

food industry has been putting together<br />

to keep these special animals content.<br />

We were surprised at how many different<br />

kinds of food there is, wet and dry, for<br />

adults, juniors and seniors. And how many<br />

toys! We spent a long time in one or two<br />

stores and took home a small selection.<br />

A cat‘s traits include its small size, social<br />

nature, obvious body language, love of<br />

play, and high intelligence. It is fascinating<br />

Ian D. Healey, Editor-in-Chief<br />

and somehow bewitching to observe<br />

and be a part of. Having accepted one<br />

cat into the extended family, we then<br />

found they often visit each other! Our<br />

garden has become a meeting place and<br />

entertainment centre and we are richer<br />

because of it.<br />

Never a dull moment!<br />

Solutions!<br />

Just as human diets are different, so are those of our pets: True<br />

to the motto "what's good for me can't be bad for my dog",<br />

owners (often unconsciously) adapt their pet's diet to their own.<br />

Preferably fresh and natural ingredients find their way into the<br />

bowl – with a demand for quality and positive health effects.<br />

The nutritional spectrum is wide ranging. Take a look at our<br />

analysis on page 14.<br />

Industrial machines are a major investment in which sustainability<br />

plays a key role. Production line components are expected<br />

to process tens of thousands of tonnes of raw materials for many<br />

years. The animal feed market is growing and producers need to<br />

keep pace. A German company has just made such an investment<br />

and relies on two automatic industrial grinders, which take high<br />

processing volumes in their stride. See page 31<br />

Spotlight on Protein Sorting<br />

Maximizing protein´s profitability from meat, poultry, rendering and pet food<br />

Producing and selling tasty, protein-rich petfood shouldn’t be compromised. TOMRA's equipment helps prevent unwanted foreign<br />

materials. Photos: TOMRA Food<br />

There’s money in protein. Whether<br />

it’s meat or poultry, and whether it’s<br />

processed for human consumption or<br />

rendered for pet food, it’s worth making<br />

the effort to extract every possible<br />

kilogram of saleable raw materials. But<br />

this is a business with risks.<br />

For one thing, derived meat for rendering<br />

delivered by slaughterhouses typically<br />

contains foreign materials, and these can<br />

be so difficult to detect that they get all<br />

the way down the processing line into the<br />

final product. For another, when rendered<br />

meat and poultry are turned into dry<br />

pet food, one type of kibble can easily<br />

get cross-contaminated with another,<br />

so that packages mistakenly contain<br />

unlisted ingredients. And if potentially<br />

harmful products get into the hands of an<br />

unhappy customer with a cellphone and<br />

social media access, the retailer’s brand<br />

reputation can quickly be damaged.<br />

These threats mean it is crucial for<br />

processors and renderers to have<br />

effective safeguards in place to protect<br />

food safety and product quality, whilst<br />

also minimizing food waste to improve<br />

sustainability and profitability. These<br />

things have always mattered, of course,<br />

but shifting consumer expectations make<br />

them more important now than ever<br />

before.<br />

Risks, yes - but potentially big<br />

rewards<br />

The risks and rewards of meat processing<br />

and rendering are increasing for two<br />

big reasons. One is that consumers have<br />

become far less tolerant of imperfections<br />

in the food they buy for themselves or<br />

their pets. The other is that the demand<br />

for high-quality, protein-rich foods for<br />

people and pets is growing fast.<br />

In fact, mankind’s need for proteins is<br />

set to skyrocket. The United Nations’<br />

Food and Agriculture Division predicts<br />

that by 2050 global meat production<br />

will double - yes, double! - as the world’s<br />

population increases from 7.9 billion<br />

people to 9.8 billion. At the same time,<br />

increasing wealth in developing nations<br />

will empower greater numbers of people<br />

to spend more on food.<br />

Demand for pet food is also booming.<br />

Market researchers forecast that this<br />

market’s global value will increase in the<br />

next seven years at a compound annual<br />

growth rate of almost five percent, from<br />

$94bn in 2020 to $137bn in 2028. What’s<br />

more, this market is being reshaped<br />

by the ‘humanization’ of products that<br />

contain fresh ingredients, superfoods,<br />

and high protein - and premium products<br />

can command premium prices.<br />

Increasing meat production is good news<br />

for processors and renderers, but there is a<br />

downside: meat and dairy production are<br />

responsible for a whopping 14% of global<br />

greenhouse gas emissions. This means it’s<br />

imperative to minimize food waste - not<br />

only by getting retailers and consumers<br />

into the habit of throwing away less, but<br />

also by making more efficient use of the<br />

potentially usable food in livestock.<br />

For these reasons, rendering is an<br />

environmentally-friendly way to recycle<br />

material that would otherwise be wasted<br />

- and it also reduces the greenhouse<br />

gas emissions that would come from<br />

6<br />

the natural decomposition of animal<br />

parts in compost or landfill. The National<br />

Renderers Association in the USA<br />

calculates that rendering animal tissues<br />

rather than leaving them to decompose<br />

has the same effect on greenhouse gas<br />

emissions as removing 12.2 million cars<br />

from the road.<br />

Sorting machines solve the<br />

problems<br />

Thanks to technical advances, there<br />

are solutions to all of these challenges.<br />

TOMRA Food, the leading manufacturer of<br />

sensor-based sorters for the food industry,<br />

offers machines that safeguard brand<br />

reputations and enhance sustainability<br />

by reducing food waste, protecting food<br />

safety, and consistently maintaining high<br />

product standards.<br />

The TOMRA 5B safeguards producers and brands against complaints and recalls<br />

Modern optical sorting machines also<br />

solve the widespread problem of labor<br />

scarcity, as well as helping to eliminate<br />

the health risks inherent on processing<br />

lines - as the COVID-19 pandemic drags<br />

on - when people have to spend a long<br />

time standing close to each other. And<br />

whereas manual sorting is subjective,<br />

imperfect, and especially vulnerable<br />

to errors when laborers are tired or<br />

bored, automated sorters work from the<br />

beginning to the end of each shift with<br />

unflagging accuracy.<br />

TOMRA’s sorters detect and eject<br />

unwanted materials from processing<br />

lines that simply cannot be seen by the<br />

human eye or inferior machines. They do<br />

this by inspecting materials according<br />

to their shape, color, structure, size, and<br />

even their biological characteristics.<br />

TOMRA also offers machines with x-ray<br />

technology to detect the presence in<br />

food of high-density foreign materials.<br />

For additional advantages, TOMRA’s<br />

machines can be connected to TOMRA<br />

Insight, a web-based data platform that<br />

gathers sorting data in real-time and<br />

stores this securely in the cloud. Live<br />

data can be reacted to immediately<br />

(and remotely) to optimize machine<br />

settings; historical data can be used<br />

to quantify and compare the quality<br />

of materials from suppliers. Such data<br />

analysis will become increasingly<br />

valuable as we move into a digitized<br />

future, transforming sorting from an<br />

operational process into a strategic<br />

management tool.<br />

So, let’s take a brief look at the sorting<br />

machines best-suited to meat and poultry<br />

processors, rendering plants, and pet food<br />

processors.<br />

Solutions for meat and poultry<br />

TOMRA offers sorting solutions for a wide<br />

variety of meat and poultry applications.<br />

These are for frozen products such as<br />

ground meat, nuggets, patties, and bacon<br />

bits, and for fresh raw products such as<br />

sausages.<br />

TOMRA also offers inline inspection<br />

systems. These help processors determine<br />

the right fat percentage for any grinder/<br />

mixer set-up for minced meat, burgers,<br />

and sausages, as well as making real-time<br />

measurements of protein and moisture<br />

levels. And the QV-P in-line detection<br />

machine for chicken fillets helps ensure<br />

that fillets with ‘wooden breast’ don’t end<br />

up in the final packaging.<br />

Producing and selling tasty, protein-rich<br />

sausages shouldn’t be compromised by<br />

having casing residues still attached to<br />

the final product (or by any other foreign<br />

material, for that matter). The TOMRA<br />

5B safeguards producers and brands<br />

against complaints and expensive recalls<br />

by detecting even the smallest casing<br />

fragments. The TOMRA 5B also controls for<br />

sausage length, dimensions, discoloration,<br />

and breakages. And there’s the option to<br />

sort out the rejects in two streams - one<br />

for foreign materials and casing remains,<br />

and one for products that don’t match the<br />

set scope but can be reused, minimizing<br />

food waste.<br />

For IQF products such as chicken nuggets<br />

or stripes, bacon bits, or other breaded<br />

or un-breaded products, the best sorters<br />

are the TOMRA 5C. Located after the<br />

freezer and close to packaging, this unit<br />

sets the benchmark in product safety<br />

at the same time as minimizing false<br />

rejects and food waste. By using new,<br />

best-in-class laser technology combined<br />

with TOMRA’s unique BSI+ (biometric<br />

signature identification) scanner, the<br />

unseen becomes visible, making foreign<br />

materials a problem of the past. These<br />

technologies are also highly effective at<br />

sorting-out discoloration, black spots,<br />

embedded plastic, doubles, thin coating,<br />

and voids.<br />

Sorters for pet food and<br />

rendering<br />

Producing food for pets is strictly<br />

regulated by local and global legislation<br />

which is designed to ensure product<br />

quality and food safety. Complying with<br />

these regulations requires the use of<br />

safe ingredients and additives, hygienic<br />

processing practices, and HACCP (hazards<br />

analysis and critical control points)<br />

management - but even so, there is still<br />

the risk of foreign materials entering the<br />

manufacturing facility in raw materials.<br />

This is why TOMRA works closely not<br />

only with pet food manufacturers, but<br />

also with their suppliers in the rendering<br />

industry.<br />

Important protein sources in both wet<br />

and dry pet food are animal-derived<br />

ingredients. However, entering the<br />

rendering facilities these ingredients<br />

Issue 3 <strong>2023</strong><br />



the TOMRA 5B is the perfect solution,<br />

ensuring that only the right products get<br />

into the package.<br />

In wet pet food, the TOMRA 5B is ideal<br />

for the inbound set-up, where incoming<br />

frozen blocks pass through either a breaker<br />

or a grinder before entering the mixer.<br />

Placed between the breaker/grinder and<br />

mixer, the TOMRA 5B effectively detects<br />

and sorts various foreign materials<br />

including stones, hard and soft plastics,<br />

metal, wood, glass, rubber and bones. In<br />

addition to protecting final products from<br />

unwanted materials, the TOMRA 5B also<br />

logs every batch, so it is possible to assess<br />

what’s coming from suppliers accurately.<br />

The TOMRA 5C sets the benchmark in product safety<br />

often contain various foreign bodies<br />

which come from the abattoirs, such as<br />

rubber parts, foils, wood, glass, and metals.<br />

This is hard to avoid with an automated<br />

production line, but also mostly hard to<br />

detect with conventional methods such<br />

as metal detection and/or X-ray.<br />

The TOMRA 5C solves this, preventing<br />

foreign materials from reaching the pet<br />

food manufacturer. This sorter often acts<br />

as the final control on the meal line: placed<br />

after the final screen, it not only detects<br />

and rejects even the smallest particle<br />

of foreign material but also sources out<br />

all the good product coming from the<br />

screen, feeding this into the good stream<br />

again. These capabilities, plus the ability<br />

to regulate the ash content to enhance<br />

the final quality, make the TOMRA 5C<br />

essential for every meal stream.<br />

In dry pet food, foreign material isn’t the<br />

only threat - there’s also the problem of<br />

cross-contamination. And as a solution,<br />

the TOMRA Nimbus is unbeatable. This<br />

machine’s various sensors protect against<br />

foreign materials, loose and embedded,<br />

and cross-contamination - and with<br />

TOMRA’s new pet food software, the<br />

change over from one recipe to the next<br />

is like a snap of the fingers. This eliminates<br />

traditional ways of trying to avoid crosscontamination<br />

which are both timeconsuming<br />

and product-consuming.<br />

TOMRA’s unique BSI+ technology checks<br />

the inside of materials, ensuring that<br />

different types of kibble don’t get mixed<br />

even if they are near-identical in outward<br />

appearance, and by using the new<br />

petfood software, the operator always has<br />

the best view on what to produce next.<br />

For producing best-in-class pet treats<br />

and snacks, foreign materials must be<br />

prevented from ending up in the final<br />

package, and products should have<br />

the same size, form and color. For this<br />

The accurate removal of foreign bodies such as food bones and meat is critical<br />

An investment that pays back<br />

well<br />

When processors and renderers first<br />

adopt TOMRA’s sorting solutions, they<br />

are pleased to find that the once-steady<br />

trickle of customer complaints dries up.<br />

One good example of this is JG Pears, a<br />

leading processor of animal by-products<br />

and food waste in the UK, producing a<br />

range of meals and fat for the pet food<br />

industry. The company’s Site Manager,<br />

Craig Harrison, said: “Non-conformances<br />

with our customers have reduced<br />

dramatically, and we see very, very little<br />

waste or foreign bodies in our material.<br />

Our current customers have seen the<br />

difference in the finished product and<br />

there’s lots of interest from additional<br />

customers enquiring about buying our<br />

material.”<br />

In addition to keeping customers happy,<br />

then, TOMRA’s sorting machines are also a<br />

key which can unlock new business. One<br />

of many business leaders who will affirm<br />

this is Andy Kettle, Managing Director of<br />

GA Pet Food Partners, Europe’s leading<br />

manufacturer of private label premium<br />

dry pet food. Andy commented: “TOMRA’s<br />

technology has helped us break open new<br />

markets which previously would not have<br />

been available to us. For me, it has been<br />

one of the best investments made by the<br />

business in the last three to four years.”<br />

Tereos Launches Profeed<br />

ADVANCED®, a Complementary<br />

Feed to Support Dogs’ Immune<br />

Function<br />

Tereos is launching Profeed ADVANCED®,<br />

a complementary feed that is proven*<br />

to support the immune defence system<br />

in aging dogs. Developed jointly with<br />

Lallemand, a leading company in the<br />

development of yeast, bacteria, and<br />

their derivatives, Profeed ADVANCED®<br />

combines Tereos’ short-chain fructooligosaccharides<br />

(scFOS), already known<br />

as Profeed®, with new and unique selected<br />

yeast fractions to tackle the gut microbiota<br />

and immune changes in elderly dogs.<br />

Obtained from sugar beet sucrose,<br />

Profeed® short chain FOS encourages the<br />

growth of beneficial gut bacteria, while<br />

new Profeed ADVANCED® combines these<br />

proven prebiotic effects with the action of<br />

specifically selected yeast fractions, acting<br />

as postbiotics. This results in a synergistic<br />

effect for a unique complementary feed –<br />

for which a patent is still pending.<br />

Dr. Cindy Le Bourgot, Nutrition & Health<br />

Scientist at Tereos, explains: “Tereos’<br />

Profeed® range has been a favorite with<br />

petfood manufacturers for many years,<br />

and Profeed ADVANCED® is a real step<br />

forward in helping dogs stay healthier for<br />

longer. Science and innovation have come<br />

together to create a symbiotic product<br />

based on complementary modes of<br />

action, helping older dogs to stay healthier<br />

for longer.”<br />

In dogs, as in humans, the aging process<br />

leads to an alteration of the gut microbiota<br />

and a decrease in the efficacy of the<br />

immune system. Profeed ADVANCED®<br />

has been designed to support a balanced<br />

microbiota while sustaining the immune<br />

system through aging.<br />

Dr. Francesca Susca, Global Pet Product<br />

Manager at Lallemand Animal Nutrition<br />

(Tereos’ development partner), added:<br />

“Lallemand has worked for many years<br />

developing yeast and bacteria and their<br />

derivatives for humans and animals.<br />

We have selected specific yeast strains<br />

for Profeed ADVANCED® to develop<br />

a complementary feed with proven<br />

benefits in balancing the microbiota of<br />

senior dogs and helping to maintain their<br />

immunity. This is the first yeast derivatives<br />

product of this kind in the market.”<br />

Manufactured at Tereos’ facility in<br />

Chevrieres, France, the feed comes in the<br />

form of a neutral-tasting powder that can<br />

be added to any wet or dry petfood by<br />

manufacturers.<br />

finding suitable low glycaemic<br />

ingredients for dog food is key.<br />

A new series of in-vitro and in-vivo studies<br />

initiated by BENEO and conducted by<br />

Corbee et al i , have evaluated the digestion<br />

of isomaltulose, as well as its glycaemic<br />

and insulinaemic effects in dogs,<br />

compared to other relevant carbohydrate<br />

sources. The study results demonstrate<br />

that isomaltulose is a suitable low<br />

glycaemic ingredient for use in dog food,<br />

triggering a lower blood glucose rise after<br />

consumption. This property makes it a<br />

particularly interesting solution with the<br />

potential to support metabolic health<br />

and weight management.<br />

Numbers of overweight and obese<br />

dogs have steadily increased over the<br />

last few decades and exceed 50% in<br />

Western countries ii . Excessive weight<br />

is linked to metabolic and skeletal<br />

associated disorders and impacts the<br />

quality of life of both dog and owner.<br />

This is reflected in pet owners’ interest<br />

in tackling such issues: More than 8 in<br />

10 pet owners worldwide agree that onpack<br />

communication about helping to<br />

control their pet’s weight naturally (87%),<br />

or having a lower impact on blood sugar<br />

levels (85%), very much or somewhat<br />

affects their purchase intention of a pet<br />

food product iii . Here, nutrient choice has<br />

In total, three studies were carried out by<br />

the teams from universities in Utrecht and<br />

Wageningen. The first, an in-vitro study<br />

of small intestinal tissue samples from<br />

three dogs, evaluated the small intestinal<br />

hydrolysis of isomaltulose compared<br />

to sucrose, maltose, maltodextrin,<br />

lactose and α-trehalose. The aim was to<br />

confirm if dogs have the ability to digest<br />

isomaltulose, as well as compare it with<br />

other carbohydrate sources. The findings<br />

showed that it can be digested by canine<br />

intestinal enzymes, with a lower enzyme<br />

activity compared to high glycaemic<br />

carbohydrates, indicating a slower rate of<br />

hydrolysis.<br />

The second and third studies compared<br />

the effects of isomaltulose, sucrose and<br />

maltodextrin in an in-vivo set-up. One<br />

of the studies assessed the glycaemic<br />

effects of the three carbohydrates<br />

in nine dogs and using a 3x3 Latinsquare<br />

design v . After an overnight fast,<br />

the blood glycaemia and insulinaemia<br />

were measured 0-180 minutes after<br />

the administration of a single dose<br />

of either isomaltulose, sucrose or<br />

maltodextrin. The results showed that<br />

isomaltulose significantly lowered<br />

blood glucose and insulin responses in<br />

the dogs, compared to maltodextrin or<br />

sucrose.<br />

The goal of the final study was to assess<br />

the glycaemic properties of isomaltulose<br />

in dogs, after continuous intake. This was<br />

based on the assumption that the abilities<br />

to digest isomaltulose might evolve<br />

through adaptation, so that its impact on<br />

blood glucose levels would get closer to<br />

the other carbohydrates. In this study, 18<br />

dogs received a 50:50 mix of isomaltulose<br />

and sucrose (1g per kg bodyweight) daily<br />

for two weeks. They were then split into<br />

three equal groups which each received<br />

a single dose of either isomaltulose,<br />

sucrose or maltodextrin after an<br />

overnight fast. Following this, the dogs’<br />

blood glucose and insulin responses were<br />

measured. Even after continuous intake<br />

over two weeks, the low glycaemic and<br />

insulinaemic properties of isomaltulose<br />

were confirmed.<br />

About BENEO<br />

BENEO-Animal Nutrition offers a broad<br />

range of natural ingredients with<br />

nutritional benefits. The product range<br />

is comprised of vegetable proteins,<br />

digestible carbohydrates, prebiotic<br />

chicory root fibers and specialty rice<br />

ingredients. BENEO-Animal Nutrition<br />

extends BENEO´s unique expertise in<br />

human food to the world of pet food,<br />

livestock feed and aqua feed.<br />

Commenting on the findings, Dr Maygane<br />

Ronsmans, Product Manager Animal<br />

Nutrition at BENEO says: “This research<br />

is of great importance as it offers the<br />

first comprehensive characterisation<br />

of isomaltulose with respect to its<br />

digestibility and metabolic effects in<br />

dogs. The low glycaemic properties of<br />

isomaltulose already shown in other<br />

species, including humans, pigs and<br />

rodents, have now been confirmed in<br />

dogs. The combined results of this study<br />

suggest that isomaltulose would be<br />

a suitable energy source in dog food,<br />

which contributes to a more stable blood<br />

glucose response, and may improve the<br />

dog’s metabolic profile and overall health.”<br />

Isomaltulose is a disaccharide which<br />

occurs naturally in honey. It is composed<br />

of glucose and fructose, characterised by<br />

a stronger glycosidic bond than that of<br />

usual sugar. Isomaltulose is a direct source<br />

of energy that generates a more balanced<br />

blood glucose response, distinguishing<br />

it from high glycaemic energy sources,<br />

such as heat treated cereals and<br />

conventional sugars (e.g. dextrose).<br />

BENEO derives isomaltulose from sugar<br />

beet at its production plant for functional<br />

carbohydrates in Offstein, Germany.<br />

High-quality, Functional, and<br />

Sustainable: the Current Trends in<br />

Natural Dog Nutrition<br />

Just as human diets are different, so are those of our pets: True to the motto "what's good for me can't be bad for my dog",<br />

owners (unconsciously) adapt their pet's diet more and more to their own. Preferably fresh and natural ingredients find<br />

their way into the bowl – with a demand for quality and positive health effects. The nutritional spectrum ranges from<br />

regional, vegan, and protein-rich food components, to selected organic products and individual oil blends.<br />

1. High-quality and natural pet<br />

food components<br />

The pet food market is becoming<br />

increasingly "green": more and more pet<br />

parents are paying attention to natural,<br />

sustainable nutrition and care about<br />

the health and well-being of their furry<br />

friends. This also reflects the owners’<br />

increased awareness of environmental<br />

protection and animal welfare.<br />

They increasingly value high-quality<br />

ingredients for pet food made from<br />

natural raw materials and unprocessed<br />

ingredients. "Clean Feeding" serves<br />

this trend: the concept envisions dog<br />

foods that are as natural as possible and<br />

usually consist of half animal protein,<br />

30 to 40 percent plant-based products,<br />

10 to 20 percent carbohydrates, and<br />

a small number of high-quality oils.<br />

Additives such as artificial colors, flavors,<br />

and preservatives as well as genetically<br />

modified ingredients (GMOs) are largely<br />

avoided.<br />

Pet owners are paying more attention to<br />

the origin of food and are turning to organic<br />

products, meat from species-appropriate<br />

farming, and fish from sustainable wild<br />

catches. Many manufacturers are already<br />

responding to the demand for organic pet<br />

food: with organic-certified ingredients<br />

and products, they assure their customers<br />

of an organic standard that excludes the<br />

use of chemical fertilizers, pesticides, or<br />

antibiotics. The menu also more often<br />

includes local fruits and vegetables<br />

from certified organic cultivation. Local<br />

products usually have shorter transport<br />

routes and can be consumed or processed<br />

more quickly. This has a positive impact on<br />

product quality and freshness, but also on<br />

the environment thanks to the reduced<br />

carbon footprint. Buying these products<br />

also supports local farmers and promotes<br />

the local economy.<br />

In addition to the origin of raw materials,<br />

pet owners are also interested in their<br />

sustainable processing: They demand<br />

transparency and prefer environmentally<br />

friendly manufacturing processes that<br />

gently preserve the valuable nutrients of<br />

the raw goods. Transparent label design<br />

helps them understand the composition<br />

of products better. In this way, pet<br />

owners ensure that the food chosen<br />

meets their dog's nutritional needs and<br />

can also identify and avoid undesirable<br />

ingredients in case of allergies and<br />

intolerances.<br />

2. Healthy and functional<br />

ingredients<br />

The demands on animal nutrition have<br />

become more complex in recent years<br />

– besides qualitative and sustainable<br />

criteria, it should be functional and<br />

healthy. According to a Mintel study,<br />

there is a clear trend in this direction: 63<br />

percent of German pet owners would<br />

like to know more about their pet's brain<br />

health and 57 percent are interested in<br />

food components that promote their<br />

pet's intestinal health. Functional food<br />

contains selected ingredients that, on the<br />

one hand, meet the pet's basic nutritional<br />

needs and, on the other, support its<br />

general well-being.<br />

Recently, there has been increasing<br />

demand for grain-free pet food to avoid<br />

potential allergies and intolerances and to<br />

improve intestinal health. Generally, grains<br />

are a good plant source of carbohydrates<br />

and fiber that most dogs can digest well.<br />

However, some have sensitive reactions to<br />

certain grains such as wheat or soy.<br />

This approach goes hand in hand with<br />

the trend to feed purely plant-based<br />

components. Following the example of<br />

vegetarian and vegan diets among us<br />

Technology & Marketing


humans, owners sometimes want to feed<br />

their dogs a vegan diet as well – but they<br />

do not want to sacrifice nutritional value,<br />

such as protein and amino acid content.<br />

While meat has long been considered the<br />

main source of protein in animal nutrition,<br />

nowadays more and more plant-based<br />

protein sources are being integrated into<br />

the diet.<br />

Plant-based food components<br />

Vegetable oils, such as linseed, hemp, or<br />

olive oil, can provide valuable nutrients<br />

in dog nutrition: As a partner for natural<br />

raw materials, Henry Lamotte Oils offers<br />

a broad portfolio of essential ingredients<br />

for animal nutrition.<br />

In the company's own Oil Mill Lipos, the<br />

gentle pressing of oilseeds produces highquality<br />

oils and protein-containing press<br />

cakes that are ideal as food ingredients<br />

for dog nutrition. Fine grinding turns<br />

them into LipoMill Flours, which, with a<br />

residual oil content of five to ten percent,<br />

are rich in protein and dietary fiber. They<br />

enrich pet food with valuable omega fatty<br />

acids, amino acids, minerals, and trace<br />

elements.<br />

Vegetable extrudates that resemble<br />

meat in appearance are also becoming<br />

more popular. They are produced, for<br />

example, from organic sunflower seeds<br />

using an extrusion process. The press<br />

cake contains all nine essential amino<br />

acids that neither the human nor the<br />

animal body can produce on its own.<br />

With a high protein content of over 50<br />

percent, the extrudate is an ideal vegan<br />

alternative to the conventional protein<br />

supplier meat.<br />

Algae products are also being used<br />

more frequently in animal nutrition as<br />

a plant-based alternative to fish oils.<br />

Microalgae such as chlorella or spirulina<br />

contain the valuable omega-3 fatty<br />

acids eicosapentaenoic acid (EPA) and<br />

docosahexaenoic acid (DHA). These can<br />

contribute to maintaining the health of<br />

the brain, joints, skin, and fur. In animal<br />

nutrition, algae can be added in the form<br />

of oils or flours.<br />

BARF feeding<br />

In contrast to the feeding of plantbased<br />

food components, there are<br />

many supporters of a meat-based diet<br />

with animal proteins. They associate<br />

biologically appropriate raw food (BARF)<br />

with a near-natural diet, which they<br />

believe meets the natural needs of the<br />

dog best. In this form of nutrition, pets are<br />

fed meat, bones, and innards. Fruits and<br />

vegetables are added in small quantities<br />

as components. Fish oils, for example, can<br />

be used as a supplement in the BARF diet<br />

because of their high content of omega-3<br />

fatty acids. The EPA and DHA they contain<br />

Algae Pouder<br />

have a positive effect<br />

on the cardiovascular<br />

system and are involved<br />

in many metabolic<br />

processes.<br />

In a study, researchers<br />

from the University of<br />

Winchester in the United<br />

Kingdom and Australia’s<br />

Griffith University<br />

examined three different<br />

diets for dogs and the<br />

effect on their health. A<br />

total of 2536 dogs took<br />

part in the study: 54<br />

percent of them were<br />

fed a mixed diet with<br />

components of meat,<br />

grains and vegetables,<br />

33 percent were fed<br />

exclusively raw meat<br />

(BARF) and 13 percent<br />

were fed a purely plantbased<br />

diet. Considering<br />

various indicators,<br />

specific impairments were examined,<br />

such as gastrointestinal diseases, diseases<br />

of the musculoskeletal system, and of the<br />

skin and ears. According to the study, on<br />

average, the experimental group of dogs<br />

fed a vegan diet was less susceptible to<br />

disease. In contrast, just under half of<br />

the group fed the conventional mixed<br />

diet suffered from health problems. The<br />

dogs fed raw meat did slightly better in<br />

the study. In direct comparison, however,<br />

they were significantly younger than<br />

the vegan-fed group. It is not possible<br />

to clearly determine which diet is the<br />

healthiest: A raw meat diet tends to<br />

carry an increased risk of pathogens and<br />

malnutrition, whereas the vegan diet was<br />

the least risky choice, according to the<br />

study.<br />

3. Customized<br />

product solutions<br />

Personalized products<br />

tailored to the individual<br />

needs and preferences<br />

of one's own pet are<br />

a clear trend resulting<br />

from increasing pet<br />

humanization. Pet<br />

owners consider their<br />

pets as family members<br />

and companions for life,<br />

whose well-being they<br />

want to ensure in all<br />

respects. For this reason,<br />

owners are intensively concerned with a<br />

healthy diet and sustainable care for their<br />

furry friends. Premiumization goes hand in<br />

hand with this development: pet owners<br />

are happy to spend more money on their<br />

dogs if they expect the products to be<br />

of high quality or if they consider them<br />

to be beneficial to their health. Beyond<br />

nutrition and care, premiumization is also<br />

evident in pet accessories and innovative<br />

services. Personalized products create<br />

individuality, strengthen the bond, and<br />

express increased attention.<br />

Individual and environmentally<br />

friendly – Private Label<br />

packaging<br />

On the manufacturers' side, this trend<br />

is also having an impact on product<br />

development. The desire for individual<br />

pet food and oil mixtures is growing to<br />

adapt the diet even better to the dog's<br />

personal needs. In the field of Private<br />

Label bottling, Henry Lamotte Oils uses<br />

its years of expertise to realize individual<br />

product ideas and manufacture<br />

according to desired specifications.<br />

Customized products need well-chosen<br />

packaging: In addition to their functional<br />

and aesthetic criteria, these also meet<br />

requirements for product protection<br />

and are increasingly made of more<br />

environmentally friendly materials<br />

that are recyclable or biodegradable.<br />

Environmentally friendly packaging<br />

solutions help reduce the carbon<br />

footprint and harmful emissions.<br />

With several options available,<br />

environmentally conscious pet owners<br />

often go for the sustainable option.<br />

Regarding oils and flours, different<br />

variants are available for feed packaging.<br />

Glass bottles for oils, for example, offer the<br />

advantage that they are easily recyclable<br />

and do not interact with other substances.<br />

However, melting them down after their<br />

single use requires high temperatures.<br />

Metal cans are unbreakable, light-proof,<br />

and customizable. They have a similar<br />

recycled content to glass bottles, but are<br />

less material-intensive, making them a<br />

possible alternative to glass.<br />

Stand-up pouches made of (kraft) paper<br />

are ideal for feed components such as<br />

flours or extrudates. In contrast to plastic<br />

tins, they are only half as heavy when<br />

empty and reduce costs and emissions<br />

thanks to their minimal transport volume.<br />

Protection of Pet Food with<br />

Natural and Cost-effective<br />

Antioxidants Solutions<br />

Innovative systems to protect new sources of animal proteins<br />

extract is showing excellent performances<br />

in various types of animal proteins and<br />

fats. Mixed tocopherols, vitamin E itself<br />

and Rosemary Extract (botanical extract)<br />

are commonly used in the industry. Our<br />

large Toco-PET range can be used to<br />

protect the many types of meals and fat<br />

used by the industry.<br />

Change is around the corner<br />

A concern for naturalness in human foods<br />

has extended to a greater awareness<br />

about additives in pet food. This has<br />

been accompanied by a slow but steady<br />

increase in the re-evaluation of the safety<br />

of synthetic antioxidants in pet food.<br />

This re-evaluation has extended to the<br />

antioxidants butylated hydroxyanisole<br />

(BHA) and butylated hydroxytoluene<br />

(BHT). Most current concerns are<br />

expressed over BHA and, in particular, its<br />

re-authorization for use in cat food.<br />

Alternatives<br />

The transition from synthetics (BHA and<br />

BHT) to natural additives might reveal<br />

that naturalness comes with a challenge<br />

– in terms of both cost and the stability<br />

of the pet food. Therefore, more attention<br />

should be paid to the synergy between<br />

naturals and ‘more acceptable’ synthetics<br />

used in food systems with proven longstanding<br />

safety, such as infant nutrition.<br />

Ascorbates, gallates and chelates work<br />

well with natural antioxidants and are costeffective.<br />

The drivers of these compounds<br />

work together and are suitable for use<br />

in the pet food process. Pet-Safe (which<br />

does not contain BHA/BHT) offers a<br />

great alternative to standard synthetic<br />

antioxidants with a very competitive cost<br />

in use. This provides a very interesting<br />

opportunity for those looking for a<br />

transition between the synthetic and fully<br />

natural solutions.<br />

Synergies of natural options<br />

During the last 20 years, Vitablend<br />

technical team has worked and developed<br />

synergistic solutions using natural and<br />

traditional active compounds to provide<br />

meals, fats, oils, petfood producers with<br />

the solution offering the best cost in use.<br />

This approach helps us developing natural<br />

system offering similar performances of<br />

traditional synthetic antioxidants. The<br />

combination of tocopherols and rosemary<br />

What’s next…. new sources of<br />

proteins<br />

To sustain the increasing demand, the<br />

industry is now looking at new sources<br />

of animal proteins. Vitablend has done<br />

extensive research to find the best<br />

alternatives to protect insect meals and<br />

fat. This type of matrix can contain up to<br />

45% fat which contains polyunsaturated<br />

fatty acids very sensitive to oxidation.<br />

In our recent studies we have tested<br />

various antioxidants systems. Antioxidant<br />

capacity was measured by the induction<br />

point (hrs) to oxidation under accelerated<br />

conditions. The study showed that our<br />

Toco-PET TR 10 L (Tocopherols and<br />

Rosemary Extract) provides a similar level<br />

of protection as a traditional BHA/BHT<br />

synthetic system, enhancing the shelf life<br />

up to 50%. Our Toco-PET TR 10 L is one<br />

example of a very versatile system which<br />

can be used to protect multiple type of<br />

meals and oils.<br />

Insects in Pet Food: Do Insect<br />

Larvae Outcompete Classic<br />

Protein Sources?<br />


The demand for insect based pet food is growing in global<br />

markets. Forecasts predict significant growth rates for pet food<br />

with ingredients derived from insects in the coming years. Pet<br />

owners desire the best possible nutrition for their four-legged<br />

companions. However, pet foods with a high meat content<br />

regularly have an unfavorable environmental footprint. Customers<br />

are becoming increasingly aware of this trait. Insect based feeds<br />

may help to significantly improve the ecological footprint of pet<br />

food. Wholesome insect granules contain valuable nutrients and<br />

thus equally offer benefits for animal health and the environment.<br />

Insect based pet food market suggests enormous<br />

potential<br />

With rising protein demand for food and feed, increasing<br />

uncertainty in global commodity markets, and not least as a result<br />

of dramatic climatic changes, demands for alternative, regionally<br />

produced nutrients are growing.<br />

Insect based feeds are projected to grow at an average annual rate<br />

of 9.3 percent in the market through 2030 (Future Market Insights,<br />

2021). These forecasts are also in line with consumer attitudes:<br />

In recent studies, up to 50 percent of the pet owners surveyed<br />

already stated that they could very well imagine insect based<br />

feeds as an alternative for their dogs and cats.<br />

Fig. 1: Insects are the most efficient users of precious raw materials<br />

In this light, many pet owners are increasingly keen to ensure<br />

that what they fill their four-legged friends' bowls with originates<br />

from sustainable sources. As an alternative to pork, poultry or fish,<br />

insects in pet food offer numerous advantages:<br />

The range of insect based pet food already is correspondingly<br />

large: Products range from snacks and chews to classic dry and<br />

wet food varieties as well as special hypoallergenic feeds that can<br />

be purchased exclusively from veterinary practices.<br />

Contributing to sustainability in pet food<br />

The production of food for around 25 million dogs and cats in<br />

German households alone not only leaves an unfavorable footprint<br />

on the eco-balance of domestic agriculture. It also contributes to<br />

global environmental impacts: Much of the soy used to provide<br />

protein for meat-supplying livestock originates from regions<br />

where valuable natural areas are cleared for its cultivation. Social<br />

tensions in the countries of origin and climatic changes worldwide<br />

clearly show that there are limits to this approach.<br />

Insects can save natural raw materials, especially large<br />

amounts of water.<br />

Insects can recycle residual materials from agriculture<br />

and the food industry into high-quality ingredients.<br />

Regionally reared insects can reduce transport distances<br />

and greenhouse gas emissions.<br />

Thanks to vertical farming, significantly less space is<br />

required for insect fattening than in conventional animal<br />

husbandry.<br />

Insect larvae - a high-quality and healthy source<br />

of nutrients.<br />

To dogs and cats the following applies as well: selected ingredients<br />

in food support important metabolic functions and promote<br />

vitality.<br />

The exoskeletons of insects, the so-called exuviae, largely consist<br />

of the polysaccharide chitin, a crude fiber component suitable for<br />

animal feed. It has also been shown that chitin and its derivative<br />

chitosan may stimulate the immune system and thus strengthen<br />

the animals' internal defenses against external influences.<br />

Wholesome insect granules as a source for pet<br />

food.<br />

The processing procedure for full-fat insect granules is<br />

coordinated in such a way that all valuable ingredients of the<br />

larvae are retained. Compared to partially defatted meals, full-fat<br />

granules utilize the entire potential of the BSFL. This high-quality<br />

raw material thus contains all the natural energy of the insect fat,<br />

and the antimicrobial and antioxidant effects of the bioactive<br />

ingredients can also be used completely.<br />

Black Soldier Fly Larvae (BSFL) naturally contain high-quality<br />

and easily digestible nutrients: protein and fat, minerals such<br />

as copper, iron, magnesium, manganese, selenium and zinc, as<br />

well as various (B-) vitamins are present in a balanced ratio. Insect<br />

protein contains all the essential amino acids, and insect fat is<br />

highly energetic and has a valuable fatty acid content - about 50<br />

percent lauric acid alone.<br />

For most pets, protein from insects is also an as yet unknown<br />

protein source and is therefore considered a promising protein<br />

alternative in case of feed allergies and intolerances.<br />

Technical aspects also speak in favor of the use of wholesome<br />

insect meal in animal feed: for example, it is much easier to utilize<br />

during processing. The material has a much lower tendency to<br />

batch and its flowability is remarkable. Feed components based<br />

on full-fat meal prove to be color- and odor-solid and enable a<br />

Bioactive ingredients stimulate internal defenses<br />

Insect larvae are exposed to numerous germs in their natural<br />

habitat and they need effective mechanisms to defend<br />

themselves against them. With the help of antimicrobial peptides<br />

(AMP) and a high content of lauric acid, BSFL keep bacteria,<br />

viruses and fungi at bay.<br />

The AMP contained in BSFL, as well as the high concentration of<br />

medium-chain lauric acid (MCFA) in the fat, also offer benefits<br />

to dogs and cats: Ingested in the feed, they can support animal<br />

health with their antimicrobial as well as antioxidant effects.<br />

Efficient Process Technology for<br />

Dogs and Cats<br />

The demand for veterinary products is increasing worldwide – and with it the need for particularly efficient, hygienic<br />

manufacturing processes. As the example of chewable tablets for dogs and cats shows, Ploughshare® Mixers can meet the<br />

specific requirements particularly well in several respects.<br />

Pet owners worldwide spend over 135<br />

billion euros on their pets. In the USA<br />

alone, the figure is almost 60 billion, in<br />

Western Europe around 30 billion – per<br />

year and rising. Veterinary medicines<br />

account for a significant proportion of<br />

this expenditure.<br />

Specialized manufacturers are<br />

responding to this growing demand<br />

by expanding their capacities, not only<br />

with additional equipment, but above<br />

all with increasingly efficient production<br />

processes. How this could look in practice<br />

is shown by a particularly widespread<br />

form of administration: Chewable tablets<br />

for dogs and cats.<br />

Raw materials and process<br />

From a technical process point of view,<br />

such chewable tablets mainly consist<br />

of dry raw materials: In the basic recipe,<br />

Active Pharmaceutical Ingredients (APIs)<br />

or other additives, such as vitamins or<br />

flavors, are added to a basic product (e.g.<br />

corn starch or protein powder). The first<br />

intermediate product is thus a powdery<br />

dry mixture.<br />

After this premixing, liquid components,<br />

e.g. liquid polymer (PEG or macrogol) or<br />

oils (e.g. soya oil, fish oil) are added and<br />

incorporated in a second step. At room<br />

temperature, however, these liquids can<br />

harden or crystallise in contact with the<br />

mixer or the mixed material before they<br />

are completely distributed. Therefore,<br />

both the mixer and the dry mix must<br />

be tempered beforehand. Usually it<br />

is heated to around +50 – 60 °C to<br />

optimise distribution of the added liquid<br />

components in the dry mixture.<br />

After another mixing process, a highly<br />

pasty, marzipan-like dough is formed.<br />

After emptying the mixer, the mixture is<br />

transferred to a moulding machine as a<br />

lump or dough strand. Finally, the formed<br />

tablets are baked through and packaged.<br />

Ploughshare®<br />

Mixer FKM as<br />

a particularly<br />

efficient<br />

solution<br />

Both mixing steps<br />

take place one after<br />

the other in the<br />

same machine and<br />

in batch operation.<br />

Ploughshare®<br />

Mixers FKM from<br />

Lödige Process<br />

Technology with<br />

600 to 3000 l<br />

nominal volume have already proven<br />

themselves many times over. They operate<br />

based on the mechanically generated<br />

fluid bed that ensures a very good mixing<br />

performance and was introduced to<br />

industrial mixing technology by Lödige:<br />

the specially developed shovels rotate<br />

close to the wall inside a horizontal<br />

drum, creating the fluid bed. The process<br />

enables a high degree of homogeneity<br />

and constant reproducibility.<br />

Treatment inside a Ploughshare® Mixer<br />

brings multiple advantages over other<br />

mixing methods: Intensive forced mixing<br />

combined with short process times<br />

ensures the highest mixing qualities and<br />

particularly efficient operation. Holding<br />

times, duration of treatment and other<br />

process variables can be modified<br />

depending on the characteristics being<br />

sought.<br />

As a further advantage, the FKM enables<br />

precise temperature control of the raw<br />

materials by means of an insulated<br />

temperature control cover on the drum.<br />

The horizontal arrangement offers<br />

significantly more contact surface than a<br />

vertical system, ensuring fast and efficient<br />

heat transfer. The cover of the insulation<br />

to the outside made of welded stainless<br />

steel guarantees the machine design<br />

according to Hygienic Design.<br />

In addition, the FKM allows liquid<br />

components to be added via mixer lances<br />

in the effective range of special choppers<br />

which rotate at up to 3000 rpm and<br />

ensure ideal distribution of even higherviscosity<br />

liquids in the mix. The sturdy<br />

design of the mixer ensures long service<br />

lives of 25 years and more and minimises<br />

maintenance.<br />

Hygienic design<br />

Ploughshare® Mixers come in various<br />

different sizes and are also available<br />

in an explosion protected version for<br />

specific applications. The customerspecific<br />

design of machines and<br />

machine lines is just as much a matter of<br />

course as strict adherence to all current<br />

GMP directives and FDA regulations,<br />

which also apply to the production of<br />

veterinary pharmaceuticals. In close<br />

cooperation with the representatives of<br />

major manufacturers of pharmaceutical<br />

products, Lödige has realized far<br />

more than 1000 systems according to<br />

requirements in the last few decades.<br />

Automatic WIP systems for reliable and<br />

reproducible cleaning of the mixer are<br />

an essential element of hygienic design.<br />

The cleaning process itself comprises the<br />

residue-free removal of any remaining<br />

product and material build-up in the<br />

entire inside of the machine. For this<br />

24<br />

Technology & Marketing


purpose, the seals on the mixing unit<br />

and choppers are switched from their<br />

usual gas flush to a water flush to prevent<br />

ingress of cleaning water into the seals.<br />

The horizontal mixer itself is cleaned<br />

successively from top to bottom. For this<br />

purpose, all inlets on top of the machine<br />

are equipped with cleaning nozzles, which<br />

are either fixed in place on the inside of<br />

the inlet or can be positioned on the inlet<br />

by means of a washing adapter. It is also<br />

possible to install automated retractable<br />

cleaning nozzles. Filters are generally<br />

completely moistened while installed and<br />

then removed for further cleaning (e.g. in<br />

a dishwasher or an ultrasonic bath).<br />

The washing water used for cleaning the<br />

inlets is collected in the mixing drum and<br />

later used for cleaning the mixing vessel,<br />

which requires a filling level of 20 - 30%<br />

with cleaning fluid. Cleaning of the mixing<br />

drum itself is carried out by means of the<br />

mixing elements, which effectively ensure<br />

intensive and turbulent contact between<br />

the mixing drum and the cleaning liquid<br />

in forward and reverse operation. If<br />

necessary, any product residue remaining<br />

in the mixer can be soaked during this<br />

process. Mixing systems with higher<br />

volumes use rotating targeted jet cleaners<br />

to clean the drum in order to maintain<br />

sustainable levels of water volume used<br />

per cleaning cycle. For this process it<br />

is possible to use both fresh water and<br />

closed loop circulation mode.<br />

Automatic cleaning of the mixer discharge<br />

is a demanding task. The reason for this<br />

is the more complex geometry of the<br />

discharge door, drive shaft and sealing<br />

surfaces. A combination of static cleaning<br />

nozzles and a centrally located rotating<br />

spray ball as well as opening and closing<br />

the door in interval mode have proven<br />

successful for intense cleaning of all<br />

surfaces. Any waste water created by the<br />

cleaning process is discharged through<br />

a drainage cone installed at the mixer<br />

discharge.<br />

Complete solution from a single<br />

source<br />

However, Lödige does not only supply<br />

the mixer(s). As a solution provider, the<br />

company also implements entire machine<br />

lines. In the case of a production machine<br />

line for veterinary chewable tablets,<br />

such a complete solution also includes,<br />

in particular, the complete dosing,<br />

temperature control, regulation and<br />

control technology for the raw materials<br />

according to CFR 21 part11 as well as<br />

the piping (also temperature controlled),<br />

the melting container, the installations<br />

for weighing and adding the individual<br />

ingredients. Lödige accompanies the<br />

customer during the implementation of<br />

the entire machine line from planning to<br />

commissioning, in particular also during<br />

the qualification process and subsequent<br />

documentation.<br />

Technology for Pet Food Snacks<br />

and Treats<br />

Pet food production with FS 510<br />

Handtmann offers a variety of modular<br />

and flexible production solutions for pet<br />

food manufacturing. Mixing, filling and<br />

portioning, cutting/dividing, forming,<br />

dosing or co-extruding a wide variety<br />

of products are their core functions.<br />

The production of formed products and<br />

treats as cubes, bars, pellets, balls, hearts<br />

and more is highly efficient possible.<br />

The outstanding feature of all systems<br />

is the exceptional portioning accuracy<br />

owing to the vane cell feed system in<br />

the basic machine, the vacuum filler. This<br />

weight accuracy significantly reduces<br />

costs, especially when processing highquality<br />

products. Also, the unique and<br />

very gentle mixing technology of the<br />

Handtmann Inotec can be optimally used<br />

for numerous applications in pet food<br />

production.<br />

One of the production solutions of<br />

Handtmann is the range of forming<br />

systems. It is characterised above all<br />

by its flexible use in many different<br />

areas of application, from soft product<br />

consistencies to firm products. In addition,<br />

a large variety of shapes is possible with<br />

countless options, such as round, square,<br />

oblong, 3D shapes in dog bone form and<br />

more. Here the filling product is fed to the<br />

flow divider by a VF 800 vacuum filler. The<br />

servo-driven flow divider ensures precise<br />

rotor speed in the flow divider. The result<br />

is a continuous product flow without<br />

pressure fluctuations, and thus accurate<br />

final weights. The flow divider ejects the<br />

filling product in multi-lane filling flows<br />

via mould components. The desired<br />

product shape is created using forming<br />

tubes positioned at the outlet. The shape<br />

can be changed easily and quickly by<br />

exchanging the forming tubes. Product<br />

separating is performed directly at the<br />

outlet, either with a wire or with a blade; it<br />

is uninterrupted and linear to the product<br />

speed. Production can be onto racks and<br />

trays as well as onto a conveyor belt. The<br />

vacuum filler’s control system allows easy<br />

visualisation of the product shape and<br />

calculation of the process parameters.<br />

Energy-saving and Reliable Drying<br />

of Cat Food<br />

An Austrian pet food manufacturer replaced their gas operated dryer with a heat pump based system. This helped to<br />

reduce their cost of operation considerably. The company is more than satisfied with the reproducible and energy-saving<br />

drying process and the excellent drying quality they can now enjoy.<br />

Rupp Food Austria GmbH is a fourthgeneration<br />

family enterprise selling dog<br />

and pet food around the world today.<br />

The business started by acquiring a mill<br />

to produce flake cereals at the beginning<br />

of the last century. Oats have been an<br />

important part of the Austrian company’s<br />

portfolio to the present day. In 1975, they<br />

started manufacturing pet food which has<br />

been their primary product ever since.<br />

Managed by Hubert and Christoph Rupp<br />

the company produces quality dog and<br />

cat food with a workforce of about 160<br />

with a focus on meeting highest quality<br />

standards throughout their business.<br />

They used a gas operated belt dryer for<br />

producing cat food. The dryer had got<br />

long in the tooth and they intended<br />

to put it out of service. It goes without<br />

saying that, today, the focus is as much on<br />

energy consumption as on good drying<br />

quality. So, Rupp studied alternative<br />

drying methods. They got in touch with<br />

Figure 1: Extruded mass of cat food before and after the drying tests. The tests were<br />

conducted to determine all parameters required to ensure successful drying.<br />

Wet cat food before drying<br />

Harter at the Powtech fair in Nuremberg<br />

in 2017. Harter is a drying system<br />

manufacturer specialized in heat pump<br />

based dryers for industry with a record<br />

of more than 30 years. "We viewed this<br />

as a great opportunity to reduce our<br />

extremely high gas consumption and<br />

the resulting cost of operation while<br />

optimising our process," reports Klaus<br />

Schiller, COO of Rupp in retrospect.<br />

The million dollar question was if this<br />

technology could meet the high quality<br />

requirements. Harter provides an answer<br />

to this question through series of tests<br />

run at their in-house pilot plant station.<br />

The German drying system manufacturer<br />

has always offered their prospective<br />

customers this option as a reasonable<br />

approach to define the exact drying<br />

parameters. Of course, products are<br />

more or less easy to be dried. This is<br />

when Harter’s typical innovation spirit<br />

comes in to find a suitable solution. The<br />

solution was found, to put it in a nutshell.<br />

Dried cat food<br />

Testing and Solution<br />

In initial tests, Harter determined the<br />

drying time, the feasibility of 70 °C as the<br />

drying temperature, and the potential<br />

bulk density. Tests of the 90 °C heat-up<br />

step revealed that the relevant portion<br />

of the conveyor belt would require<br />

a separate air recirculation system.<br />

Subsequently, Harter designed the<br />

drying system based on the parameters<br />

determined by these tests and, of<br />

course, Rupp’s specifications – 2 tons<br />

per hour maximum throughput. Another<br />

issue revealed by these tests was the<br />

formation of dust resulting from abrasion<br />

of the food. Harter first determined the<br />

quantity of material abraded per hour to<br />

be able to design the required filtering<br />

and discharge system.<br />

To meet Rupp’s requirements and the<br />

parameters obtained by testing a belt<br />

length of 19 m was required. As space<br />

was restricted, Harter’s dryer had to be<br />

designed to include five separate belts<br />

arranged one above the other. The dryer<br />

is about 5 m high and the individual belts<br />

are 5 m long each. The extruded food<br />

mass is fed into the dryer automatically.<br />

Conveyor belts connect the extruder,<br />

which is placed elsewhere, with the dryer.<br />

While being dried, the pressed mass has<br />

more and more humidity removed until<br />

the specified residual humidity of six<br />

percent on average is obtained. On its<br />

way from the topmost to the lowest belt,<br />

the mass becomes gradually drier and<br />

breaks up into the shape desired. Exiting<br />

the dryer, the cat snacks are conveyed,<br />

on a traverse belt, to the next processing<br />

station. They are finally flavored and<br />

packaged. Harter integrated a filter at the<br />

dryer exit as an anti-dusting provision.<br />

The German drying system specialist<br />

also installed additional filters inside the<br />

dryer, plus a worm and belt conveyer to<br />

discharge the material abraded.<br />

Air Routing and<br />

Dehumidification<br />

Extremely dry process air is used for drying.<br />

The airflow rate is controlled to meet the<br />

requirements of the specific product.<br />

For one thing, the product is supposed<br />

to be dried as efficiently as possible. For<br />

another thing, the snacks must remain on<br />

the belts rather than fly through the dryer.<br />

Yet, it is not only the quantity and speed of<br />

the air that matters. "Air routing is always<br />

a major factor contributing to successful<br />

drying because the air, by its very nature,<br />

invariably follows the path of least<br />

resistance," explains Michael Richter of<br />

Harter Technical Sales. It is one of Harter’s<br />

secrets of success to know how to direct<br />

the air to follow the correct path and to<br />

know the engineering tricks to achieve<br />

this. This is why there are no details<br />

disclosed here. "What counts at the end<br />

of the day is that the product is perfectly<br />

and uniformly dehumidified - and this is<br />

the goal we achieve," summarized Richter.<br />

Yet, where does the process air come from<br />

and what happens to it?<br />

Figure 2: The cat snacks are dried on five belts in vertical array to obtain the exact degree of<br />

dryness and to ensure uniform dryness. The drying process is reproducible and extremely<br />

economical owing to the heat pump technology employed.<br />

The big success of this low temperature<br />

process is its physically alternative<br />

approach. Drying is accomplished using<br />

extremely dry and thus unsaturated air<br />

passed over or through the items to be<br />

dried. It absorbs humidity excellently.<br />

Subsequently, the air is cooled – the<br />

humidity condenses to form water –<br />

reheated and returned to the drying<br />

chamber. The temperature may be varied<br />

step if required for the specific process.<br />

The drying period depends on the degree<br />

of the residual humidity desired or<br />

required. For packaged food, where the<br />

wet package needs to be dried, the drying<br />

time is often restricted to a few minutes<br />

to meet the specified process cycle time.<br />

For direct food drying, the drying time is<br />

often longer and as needed to obtain the<br />

residual humidity of the product.<br />

This process air is conditioned in a<br />

dehumidification module, which is also<br />

responsible for the condensation process.<br />

This so-called AIRGENEX®food module<br />

may be installed in various locations as<br />

required for the situation on site. With<br />

Rupp, the module is located in the same<br />

room, placed on a platform above the<br />

dryer. It is connected to the belt dryer<br />

through insulated ducting.<br />

Exhaust-Air-Free<br />

Harter’s system uses a completely closed<br />

air circuit. Exhaust air free and thus<br />

emission free drying means that Rupp<br />

is now independent of the climate and<br />

the seasons. Production areas are not<br />

affected by any humidity or exhaust air<br />

emitted by the dryer. Humans, materials,<br />

and machinery are all spared from<br />

such adverse effects. The process is<br />

reproducible and thus provides maximum<br />

reliability. Exhaust air free drying has<br />

demonstrated, in many projects, to be<br />

beneficial in terms of appearance, flavors,<br />

vitamins and other ingredients. These<br />

benefits vary, of course, with the type of<br />

product and the dryness desired. "This<br />

project was a big profit for us because<br />

using this technology we save very much<br />

money and obtain a high quality product<br />

result on top", summarizes Schiller<br />

contentedly.<br />

New Concept Revolutionizes<br />

Animal Feed Production<br />

At the heart of the production line are two automatic industrial grinders<br />

from K+G Wetter<br />

Pet food for cats and dogs is a massive<br />

growth market. Not only are the<br />

quantities of wet food, dry food and<br />

snacks produced increasing year on<br />

year – customer demand for quality and<br />

specialization is also growing.<br />

Over the past 25 years, German pet food<br />

manufacturer VetConcept has been<br />

producing pet food that is precisely<br />

tailored to the needs of our four-legged<br />

friends with health issues or special<br />

nutritional requirements. In 2019, the<br />

company built a new wet food plant<br />

in the town of Föhren near Trier. There,<br />

VetConcept’s production line relies<br />

on two K+G Wetter AW 280 automatic<br />

industrial grinders, among others.<br />

Good experience from the<br />

butchery<br />

Arthur Schäfer is VetConcept’s plant<br />

manager. The master butcher had already<br />

gained positive experience with the K+G<br />

Wetter machines at his training company.<br />

When it came to planning the new wet<br />

food plant, K+G Wetter’s automatic<br />

grinders were therefore right at the top<br />

of the pet food professional’s wish list. “At<br />

the time we enjoyed super cooperation,<br />

so it didn’t occur to me to choose any<br />

other option other than K+G Wetter as the<br />

manufacturer. The grinders are good, they<br />

work really well,” says Arthur Schäfer.<br />

“We started completely from scratch<br />

here in 2019. We were therefore able to<br />

take a clean-sheet approach to the issue<br />

of integrating such a grinder into the<br />

production line,” recalls the plant manager.<br />

“The ability to use these machines to<br />

process everything from frozen meat to<br />

fresh produce was crucial in allowing us<br />

to make our wide range of products and<br />

cope with the high tonnage per hour.”<br />

Customized modifications for<br />

line integration<br />

The K+G AW 280 automatic grinders are<br />

at the heart of production. In order to<br />

integrate them into the production<br />

line, they were correspondingly<br />

adapted to meet the customer’s<br />

requirements. For example, lifting and<br />

tilting devices for pallet boxes were<br />

added to the automatic industrial<br />

grinders, as were conveyor systems<br />

for individual block loading. Each AW<br />

280 was also fitted with a customized<br />

increased height hopper to enable<br />

block pallet loading.<br />

Another customization to ensure<br />

convenient and time-saving operation<br />

of the two large industrial machines<br />

is that the side-by-side grinders are<br />

connected via a central operating<br />

platform. This allows both grinders to<br />

be reached via a single working area.<br />

A laser level monitor checks whether<br />

the hopper is full – if so, loading stops.<br />

If the hopper is empty, the worms<br />

run briefly and then also switch off<br />

automatically – a convenient feature<br />

for optimizing production processes<br />

and protecting the cutting sets.<br />

A single machine type for<br />

two different tasks<br />

The two K+G Wetter industrial grinders<br />

fulfil two different tasks in VetConcept’s<br />

wet feed production: One of the AW 280s<br />

is only used to produce coarse material<br />

between 16 and 25 mm – i.e. what cats<br />

and dogs later find as meat pieces in their<br />

feeding bowls.<br />

The second grinder is primarily used<br />

to process products containing bones.<br />

“Wherever possible, we use bones and<br />

cartilage as a natural source of calcium<br />

in our feed. This replicates how animals<br />

would eat naturally,” reports Arthur<br />

Schäfer. “In order to mince such extremely<br />

hard material to a size of 7 to 8 millimeters,<br />

the grinder used must be sufficiently<br />

powerful and robust.” A task that the AW<br />

280 masters effortlessly before the<br />

bone mass is fed onwards into the<br />

emulsifier after grinding.<br />

Effortless processing<br />

– from frozen meat<br />

block to fresh meat<br />

Processing frozen blocks<br />

of meat presents another<br />

special challenge for the<br />

machines. Here, the K+G<br />

Wetter grinders score with<br />

a feeder worm that has a<br />

peeling edge: It already precuts<br />

the blocks as they are fed<br />

towards the meat worm, without<br />

squeezing them. The speed is infinitely<br />

adjustable, as required. The result is a<br />

clean and clear cut with no smearing and<br />

a minimal temperature increase of just<br />

1°C to a maximum of 2°C.<br />

Each of the K+G grinders is also equipped<br />

with a pre-cutter support assembly that<br />

counteracts the high pressure on the<br />

cutting set during grinding. “This makes<br />

absolute sense, because the support<br />

assembly on the pre-cutter plays a key<br />

role in minimising the pressure buildup,”<br />

says Arthur Schäfer. “On the one<br />

hand, providing support from the outside<br />

increases the service life of the cutting<br />

sets, while also noticeably reducing the<br />

number of sharpening cycles on the<br />

other. Especially important is the fact that<br />

the quality of the ground meat in terms of<br />

cutting pattern, texture and temperature<br />

is always first-class.”<br />

Perfect hygiene ensures<br />

product safety<br />

Efficiently ensuring perfect hygiene<br />

is equally as crucial in animal feed<br />

production as it is in the food industry.<br />

This is why all K+G Wetter machines<br />

are consistently optimized for hygienic<br />

design. “Of course, from a production<br />

sequence perspective, it must be possible<br />

to quickly and easily clean the machines<br />

perfectly between batches. K+G Wetter<br />

grinders are excellent in this respect,”<br />

confirms plant manager Schäfer. “Since<br />

we produce special dietary food for<br />

cats and dogs, we need to separate the<br />

batches stringently. For example, we<br />

produce mono-protein varieties such as<br />

horse, kangaroo and goat. This means<br />

that the machine must be super clean<br />

throughout when switching batches, in<br />

order to protect sensitive and allergic<br />

animals from exposure to unwanted<br />

proteins.”<br />

To make cleaning easier for the team, a<br />

clean-in-place (CIP) system is installed<br />

throughout the production hall. This<br />

allows each machine to be cleaned at<br />

any time in a single operation using hot<br />

water at 60°C, or even foam, via pipes<br />

and hoses. Thanks to the closed housing<br />

made of hand-polished stainless steel and<br />

carefully polished, smooth weld seams,<br />

the grinders themselves possess optimal<br />

cleaning characteristics and can be<br />

cleaned quickly and thoroughly right into<br />

the last corner. “Cleaning is carried out by<br />

our employees themselves,” emphasizes<br />

Arthur Schäfer. “This is important to me,<br />

because their daily experience tells them<br />

which areas need the most attention. In<br />

the evening, the machines all look like<br />

they’ve just been installed.”<br />

The CIP system can also be connected<br />

directly to the grinders; the appropriate<br />

valves have been fitted for this purpose:<br />

“We have converted the rinsing chamber<br />

so that our system’s connections fit. Foam<br />

is then introduced, followed by warm<br />

water – the system functions well,” says<br />

Arthur Schäfer. This rinsing chamber is<br />

installed as a special hygienic solution<br />

as standard in all K+G Wetter grinders.<br />

Some background: During the grinding<br />

process, the product is conveyed through<br />

the cutting set under very high pressure.<br />

Liquid product components or even small<br />

product particles can be forced through<br />

the seals into the inside of the machine<br />

against the cutting set. These particles<br />

are collected in the rinsing chamber<br />

in which sustainability plays a key role.<br />

After all, production line components are<br />

expected to function for many years while<br />

processing tens of thousands of tonnes of<br />

raw materials. “The animal feed market is<br />

growing enormously and at a rate that<br />

remains between 15 and 25 percent per<br />

annum. Of course, as a producer, you<br />

need to keep pace with this,” says Arthur<br />

Schäfer.<br />

located behind the machine, where they<br />

can be flushed out to prevent them from<br />

becoming a breeding ground for germs.<br />

Cleaning the feeder worm, which weighs<br />

over 150 kilos in the AW 280, is also<br />

accomplished in ideal fashion by means<br />

of backflushing and the CIP system: “I<br />

don’t have to lift the worm out at all, I just<br />

need to pull it out a little. Then I can rinse<br />

it completely from the outside using hot<br />

water and foam,” reports plant manager<br />

Schäfer.<br />

Sharpening service from K+G<br />

Wetter keeps knives ready for<br />

use at all times<br />

Especially in the animal feed sector, where<br />

material containing bones is processed<br />

and frozen meat is involved, it is extremely<br />

important that perfectly sharpened<br />

cutting set components are always used.<br />

For this purpose, they are replaced at<br />

intervals and sharpened accordingly. Here,<br />

VetConcept uses K+G Wetter’s sharpening<br />

service. The cutting sets are collected,<br />

sharpened and returned to VetConcept in<br />

an ongoing exchange program.<br />

Thanks to the bayonet lock nut, the<br />

cutting set can be changed in no time at<br />

all. “Of course, we plan our production<br />

schedule to avoid retooling as much as<br />

possible. But even when it’s sometimes<br />

unavoidable, retooling is quick and easy,”<br />

Arthur Schäfer reports on his experience.<br />

Future-proof investments<br />

Industrial machines such as K+G Wetter’s<br />

automatic grinders are a major investment<br />

Based on the experience gained over the<br />

past few years, VetConcept is anticipating<br />

annual growth of 20 per cent. With<br />

processing volumes of up to 8 tonnes of<br />

frozen meat blocks per hour and up to 16<br />

tonnes of pre-shredded frozen products,<br />

the AW 280 from K+G Wetter can take this<br />

in its stride – because the grinders still<br />

have plenty of excess capacity in reserve.<br />

About VetConcept<br />

VetConcept was founded in 1997. A year<br />

earlier, Torsten Herz and Anita Theis,<br />

the current managing directors, had<br />

met in the waiting room of a veterinary<br />

practice. Both had dogs with health<br />

problems. During their conversation,<br />

they quickly realized that there was no<br />

feed on the market that had a positive<br />

effect on such typical complaints. This is<br />

how the idea of VetConcept was born:<br />

Special dietetic nutrition for dogs and<br />

cats with certain health impairments<br />

that can also be adapted to age, activity<br />

and breed. The idea was quickly put<br />

into practice, with the company initially<br />

working from five garages in the Ehrang<br />

district of Trier. In 2001, VetConcept<br />

moved to the start-up center in Föhren,<br />

and in 2005, construction began on<br />

the first hall at the Dieselstrasse site<br />

in Föhren. Dry feed production is still<br />

located there today, with an output of<br />

approx. 25,000 tonnes per year. In 2019,<br />

the modern wet feed production plant<br />

was built within sight, which currently<br />

produces between 15,000 and 17,000<br />

tonnes per year. Between 12,000 and<br />

16,000 packages are shipped daily from<br />

the respective logistics halls to end<br />

customers and veterinary practices.<br />

Deadly Mycotoxins in Pet Food<br />

Cost Pet Health and Brand Trust:<br />

There is an Answer<br />

Mycotoxins, a poisonous chemical found in the corn used in pet foods, are causing animal<br />

sickness and irreparable brand damage. To solve this issue, SORTEX LumoVision, a solution<br />

developed by Swiss technology group Bühler, uses the spectral scale to kick out mold from<br />

pet food, keeping the costs of market recall down and pets safe.<br />

In 2021, the FDA (Food and Drug<br />

Administration) alerted customers of fatal<br />

levels of aflatoxin, a strand of mycotoxin<br />

that attacks the liver, found in 1,000 lots of<br />

pet food. From the bad batch, it is reported<br />

that 130 dogs died. This statistic provoked<br />

lawsuits and anger from dog owners and<br />

the wider industry. However, the damage<br />

of mycotoxin contamination does not stop<br />

there.<br />

Recalling product is expensive<br />

One of the major costs of mycotoxin<br />

contamination is market recall. Recalling<br />

a product from the market is not cheap,<br />

in fact, the Grocery Manufacturers<br />

Association (GMA) discovered that the<br />

average cost of market recall is USD10<br />

million in direct costs alone. The financial<br />

hits of recalling product include: disposing<br />

of the product, reimbursing customers,<br />

and business interruption. The GMA survey<br />

showed that 81% of respondents deemed<br />

the financial risk of market recall to be<br />

“significant to catastrophic”.<br />

Contaminated product damages<br />

brand image<br />

Financial costs and damage to health are<br />

not the only repercussions of mycotoxin<br />

contamination. Once the<br />

media are aware of the<br />

situation, brand image<br />

can take a significant hit.<br />

For consumers, it takes<br />

a lot to repair trust in a<br />

brand, and while brand<br />

damage is difficult to<br />

measure, this can further<br />

cost companies millions in<br />

lifetime value.<br />

Contaminated<br />

product can cause<br />

mass waste<br />

Before the LumoVision,<br />

contaminated grain would<br />

have been disposed of in large amounts.<br />

During testing, if the batch has a high<br />

concentration of mycotoxin, in many cases,<br />

the entire batch is destroyed. In fact, as few<br />

as 2 highly contaminated grains in 10,000<br />

can render an entire batch unsafe. The<br />

Food and Drug Association (FDA) estimate<br />

that USD932 million is lost per year to<br />

crops contaminated with mycotoxin. This<br />

removal of the contaminated material<br />

may protect the consumer, but it costs<br />

businesses and the environment a lot<br />

more.<br />

What can be done?<br />

Bühler SORTEX faced the challenge of<br />

mycotoxin contamination head-on. After<br />

discovering a breakthrough “invisible<br />

indicator” of contamination on the spectral<br />

scale, Bühler created the LumoVision,<br />

an optical sorter that can reduce the<br />

aflatoxin level by up to 90% (as indicated<br />

by industrial trials). This reduction brings<br />

many samples to regulation levels, saving<br />

companies from the costs of large-scale<br />

material waste and market recall.<br />

It works by analyzing the color each kernel<br />

fluoresces as it passes under powerful<br />

UV lighting in the sorter. It is known that<br />

contaminated kernels fluoresce a specific<br />

bright green color, a substance called kojic<br />

acid, which is produced by the Aspergillus<br />

fungus at the same time as it produces<br />

aflatoxin. LumoVision’s proprietary, highly<br />

sensitive cameras and a powerful LEDbased<br />

UV lighting system can precisely<br />

detect this color of fluorescence. Within<br />

milliseconds of detection, air nozzles<br />

deploy to blow contaminated kernels out<br />

of the product stream.<br />

When dealing with toxins, early<br />

intervention is critical. This is not only<br />

important in reducing the toxins consumed<br />

by pets, but also to lower wastage and<br />

the environmental footprint. Without<br />

proper cleaning and sorting, poisonous<br />

mycotoxins can cause large-scale wastage<br />

of materials, mass market recalls, and harm<br />

to pets.<br />

Dr Gerardo Morantes, Director of Food<br />

Safety-Americas Region at Buhler, had<br />

the following to say: “Mycotoxins are a<br />

worldwide concern. However, technology<br />

made possible by Bühler SORTEX enables<br />

a preventative solution, meaning that<br />

mycotoxins can be dealt with early,<br />

stopping the spread and removing<br />

the contamination to meet regulatory<br />

standards.”<br />

Without intervention, mycotoxin<br />

contamination can bare a large cost for<br />

businesses, including, brand reputation,<br />

market recalls and material waste. With<br />

the SORTEX LumoVision, brands can stay<br />

profitable, customers can stay happy and<br />

pets can stay safe.<br />

Sustainability in Pet Food<br />

Production? Important Steps and<br />

Solutions!<br />

by Marc Hutter, responsible for Petfood at Zeppelin Systems in Rödermark<br />

Sustainably manufacture high quality food? This is the goal of many pet food manufacturers. For this, equipment and<br />

components are required that are specially adapted to the needs and requirements of manufacturers. This ensures not<br />

only high volumes, but also the highest quality levels. They should also aim to reduce material rejects. How is this possible?<br />

With the help of plant engineering solutions from Zeppelin Systems! We Create Solutions!<br />

The demand for animal food is constantly<br />

increasing: In Germany, more than 34<br />

million pets of different species now live<br />

in 46 percent of all households. In 2007,<br />

it was 23.2 million – with most pets being<br />

cats and dogs. Their owners have very<br />

specific ideas about the appearance and<br />

composition of the food for their beloved<br />

companions: pet food should be round<br />

or square, red or brown. Apart from color<br />

and shape, one thing stands out above all:<br />

No harmful additives! For manufacturers,<br />

this product variety means frequent<br />

batch changes and high cleaning costs.<br />

As a result, large quantities of production<br />

waste is generated, which plant operators<br />

have to transport away and dispose of<br />

at great expense. This not only drives<br />

up costs, it is also unsustainable. For<br />

this reason, specialists from Zeppelin<br />

Systems developed a special procedure<br />

to reprocess discarded material and<br />

return it to the production process. A<br />

great example of a functioning circular<br />

economy in the pet food production<br />

process! We Create Solutions!<br />

An important step towards<br />

sustainability<br />

Pet food manufacturers have long been<br />

aware that sustainable technologies are<br />

worthwhile. Systems and components<br />

should therefore be designed in such a<br />

way that they can avoid waste and save<br />

resources. And this is precisely where<br />

the new process from Zeppelin Systems<br />

comes in – the same one that has<br />

already won over customers in the food<br />

industry. The rejects produced during<br />

frequent batch and product changes are<br />

first put into an aqueous solution in a<br />

separate tank with an agitator. When the<br />

suspension has reached the appropriate<br />

viscosity and correct temperature, the<br />

plant operator can return this mixture to<br />

the actual process. This saves on disposal<br />

and transport costs, uses fewer raw<br />

materials and also improves the carbon<br />

footprint.<br />

Zeppelin Systems supports pet food<br />

manufacturers in this process as well<br />

as many other processing stages. This<br />

starts with raw material intake, extends<br />

to silo filling and grinding technology,<br />

right through to formulation-specific<br />

dosing and pneumatic conveying. In<br />

addition, there are inline screening<br />

machines upstream of the mixers, as well<br />

as components that dedust and temper.<br />

Quality assurance measures and concepts<br />

for explosion protection are also part of<br />

the scope of supply of the experienced<br />

plant manufacturer.<br />

Notable developments in recent years:<br />

The customer receives their customized<br />

system with the required performance<br />

combined with the highest level of<br />

accuracy. This can only be achieved if<br />

those responsible keep an eye on the<br />

entire raw material handling process. The<br />

experts at Zeppelin Systems master all<br />

process steps and the respective process<br />

and measurement technology down to<br />

the last detail. This means that the system<br />

builders can offer perfectly coordinated<br />

complete solutions from a single source.<br />

Tailor-made solutions<br />

At first glance, the individual technologies<br />

do not appear complicated; however,<br />

the processes are still changing. Gentle<br />

pneumatic transport is now playing an<br />

increasingly important role – after all,<br />

neither animal lovers nor producers are<br />

happy with crumbs in their dry food.<br />

Dense phase conveying (Dense-Tec)<br />

achieves this feat without destroying the<br />

structure of the feed. The process is now<br />

state-of-the-art and replaces mechanical<br />

conveyor technology. It is more flexible,<br />

prevents contamination and ensures<br />

high quality results. The pet food industry<br />

mainly employs Dense-Tec continuously<br />

between the individual process steps of<br />

drying, cooling and coating.<br />

For example, when weighing and dosing<br />

small quantities, plant operators must<br />

evenly distribute small amounts of<br />

vitamin powder in mixtures of several<br />

tons. Zeppelin has developed manual and<br />

automated solutions specifically for these<br />

small components. These are customized<br />

systems for batch weighing or differential<br />

scales including control. For liquids,<br />

volumetric and gravimetric components<br />

such as liquid scales and mass flow meters<br />

are available. The focus here is on ensuring<br />

that users can dose and weigh accurately<br />

and without contamination. This is<br />

why extremely accurate measurement<br />

technology is also important.<br />

Another challenge for manufacturers is<br />

the variety of raw materials. These can<br />

also differ from region to region and, for<br />

example, have different bulk densities and<br />

properties. This has an effect on handling<br />

as well. One solution to these problems<br />

is flexible systems that can be adapted<br />

without major conversions.<br />

Safe, clean and efficient<br />

Quality requirements in the pet food<br />

sector are now based on those in the<br />

food industry. It’s about preventing<br />

cross-contamination, producing cleanly,<br />

making cleaning easier and maintaining<br />

hygiene standards. That’s why Zeppelin<br />

Systems has been relying on stainless steel<br />

as a material for a long time. To ensure<br />

that the customer can easily trace the<br />

individual batches, the plant engineers<br />

have developed a process management<br />

system. This means that every change<br />

to the recipe can be logged and the<br />

origin of all delivered raw materials can<br />

be traced. Customers are also able to<br />

archive and retrieve all production data<br />

Figure 2: Presentation of a flow chart for the sustainable production of pet food<br />

and batch reports. The advantage: If<br />

the manufacturer focuses on control,<br />

automation and documentation, they<br />

offer the consumer peace of mind.<br />

Other topics that also address the<br />

sustainability aspect are energy efficiency<br />

and effectiveness. This is especially<br />

important for large systems with higher<br />

flow rates. Zeppelin Systems replaces<br />

mechanical conveyors with pneumatic<br />

conveyors, for example. These can handle<br />

longer distances without any problems<br />

and are virtually maintenance-free.<br />

To ensure process reliability and high<br />

availability, the systems of the system<br />

builder are equipped with intelligent<br />

automation technology and extensive<br />

sensor technology. Zeppelin Systems also<br />

offers on-site service and digital services<br />

such as remote access. This is now part of<br />

everyday life in the pet food industry.<br />

by Dr. Bettina Plaumann, Kuraray Europe, Segment Team Paper & Packaging<br />

Innovative approaches for paper-based packaging with polymers<br />

Various trends and requirements are currently transforming the packaging market: renewable raw materials, reducing<br />

the amount of packaging material, cutting CO2 emissions, monolayer packaging, recyclability, repulpability and<br />

biodegradability – to name a few. The overriding and most urgent trend in packaging is sustainability. That has resulted<br />

in the development of packaging concepts centered on sustainability for various types of products. In the dry pet food<br />

market, however, conventional paper packaging is considered problematic because it uses halogenated fluoropolymers to<br />

create a barrier to fat. In this sector, applying a very thin layer of carefully selected plastics may make more sense and be<br />

more sustainable.<br />

such as fluoropolymers are highly<br />

controversial because of their potential<br />

harmful effect on the human – and<br />

animal –- organism. Moreover, pet food<br />

packaging containing fluoropolymers is<br />

extremely difficult to recycle. New, more<br />

sustainable alternatives to the common<br />

packaging types used at present need to<br />

ensure a similar barrier to aroma, odor<br />

and grease.<br />

The pet food market is booming<br />

In industrialized countries, the pet food<br />

market has grown rapidly in recent years<br />

– in parallel with the number of pets. The<br />

restrictions imposed during the pandemic<br />

doubtless contributed to the increased<br />

interest in pets, which has also led to a<br />

boom in pet food. In fact, the number of<br />

packaging units sold is growing faster for<br />

dog and cat food than for any other type<br />

of fast moving consumer goods (FMCG):<br />

the compound annual growth rate (CAGR)<br />

was around 25 percent between 2015 and<br />

2020.<br />

Paper is regarded as<br />

sustainable<br />

Consumers generally regard paper-based<br />

packaging as more sustainable. That<br />

applies to food for human consumption<br />

as well as pet food. However, it is vital<br />

to ensure that innovative packaging<br />

solutions continue to meet the full range<br />

of functional requirements for food or<br />

- in this case – pet food packaging. That<br />

is an inherent challenge for paper-based<br />

packaging because a reliable barrier to<br />

the fat content of pet food is essential.<br />

For example, cat food generally has a 10<br />

percent fat content while the fat content<br />

of dog food is typically up to 20 percent.<br />

Fluorinated hydrocarbons are<br />

problematic<br />

In conventional paper-based packaging,<br />

the essential greaseproof barrier is<br />

normally achieved with the aid of very<br />

problematic substances: fluorinated<br />

hydrocarbons. Halogenated polymers<br />

Intelligent new packaging<br />

concepts<br />

The four paper-based packaging<br />

innovations presented here meet these<br />

requirements because their barrier<br />

properties are based on Kuraray’s futureoriented<br />

polymers. These packaging<br />

solutions, some of which are already in<br />

commercial use, are ideal replacements<br />

for paper and cardboard-based<br />

packaging with greaseproof properties<br />

based on fluoropolymers. They combine<br />

sustainability with functionality.<br />

1. EXCEVAL-coated paper bags<br />

Example of a conceptual structure for<br />

such packaging:<br />

Paper / moisture barrier coating / EXCEVAL<br />

coating / heat-sealable coating<br />

This type of paper-based packaging is<br />

already in commercial use in the food<br />

sector. A thin, water-soluble EXCEVAL<br />

coating acts as an oxygen and aroma<br />

barrier. EXCEVAL is a halogen-free,<br />

hydrophobically modified polyvinyl<br />

alcohol (PVOH) from Kuraray. It has been<br />

specifically developed to ensure that it is<br />

resistant to water, oil and grease. EXCEVAL<br />

can be applied to paper using conventional<br />

coating equipment such as rotogravure<br />

coaters and rod coaters. Dispersions of<br />

polyolefin or other polymers are used as a<br />

heat-sealable coating on the inside of the<br />

packaging. The big advantage of these<br />

structures is that they can be repulped<br />

without problem in standard paper mills.<br />

Repulping is a technology approach that<br />

has been established in the paper industry<br />

for many years. However, it cannot be<br />

used for fluoropolymers because they are<br />

not soluble in water.<br />

2. Paper-based pouches with<br />

a vacuum metallized layer of<br />

EVAL and BOPP<br />

This packaging concept is based on the<br />

following conceptual structure:<br />

Paper / vacuum metallized EVAL EVOH BOPP<br />

/ laminated cast polypropylene<br />

Kuraray’s ethylene vinyl alcohol<br />

copolymers (EVOH) are marketed<br />

as EVAL. A film made from EVAL<br />

EVOH and biaxially-oriented<br />

polypropylene (BOPP) is<br />

metallized under vacuum with a<br />

thin layer of aluminum, creating<br />

a barrier to aroma, oxygen, light<br />

and moisture. A simple cast<br />

polypropylene foil is laminated<br />

onto the inside of the pouch to<br />

act as the sealing layer. A tenter<br />

frame is used for coextrusion of<br />

the BOPP and EVOH for the outer<br />

layer. This packaging concept<br />

avoids the use of a far greater<br />

amount of aluminum in the form<br />

of aluminum foil. Nevertheless,<br />

EVAL EVOH provides an<br />

excellent substrate for vapour<br />

deposition of aluminum as<br />

well as an extremely reliable<br />

oxygen and aroma barrier. The<br />

packaging therefore prevents<br />

oxidation of the fats contained<br />

in dry pet food. The vacuum metallized<br />

layer is a very good light barrier and<br />

preserves the vitamin C in the pet<br />

food. This packaging concept uses the<br />

Photo: shutterstock_2014776479<br />

smallest possible amount of plastic and<br />

also optimizes the repulpability of the<br />

paper fibers because they can easily<br />

Safety and reliability are top priorities for pet owners when it comes to their<br />

beloved animals. The increasing demand for premium quality, high flexibility<br />

and limitless reliability is constantly presenting petfood producers with new<br />

challenges!<br />

be separated from the small amount<br />

of polymers in the washing-step<br />

system. The reduction in the<br />

amount of aluminum deposited<br />

also makes the polymers used<br />

in this paper packaging<br />

recyclable.<br />

3. Paper-based<br />

pouches with a<br />

metallized film layer<br />

of EVAL and MDO-PE<br />

This packaging concept<br />

is based on the following<br />

conceptual structure:<br />

Paper / vacuum metallized EVAL EVOH<br />

MDO-PE / CPE<br />

This paper packaging is based on the<br />

same principle as the previous example.<br />

However, in this case, the ethylene<br />

vinyl alcohol copolymer (EVOH) is<br />

combined with polyethylene instead of<br />

polypropylene. The inner sealing layer is<br />

made of polyethylene and the vacuum<br />

metallized film and EVAL EVOH are<br />

deposited on machine-direction oriented<br />

polyethylene (MDO-PE). Thanks to the<br />

tremendous technological advances<br />

that machine manufacturers have made<br />

in production equipment for multilayer<br />

film in recent years, multilayer films with<br />

MDO-PE have become an attractive<br />

alternative. Using MDO technology, both<br />

cast and blown co-extruded films can<br />

be uniaxially oriented to achieve better<br />

properties. This packaging concept also<br />

prevents oxidation of fat and preserves<br />

the vitamin C in pet food. The packaging<br />

does not contain any aluminum foil or<br />

BOPET. Moreover it uses the smallest<br />

possible amount of polymer and allows<br />

problem-free repulping of paper fibers.<br />

4. Repulpable paper packaging<br />

with PLANTIC biopolymer<br />

This packaging concept is based on the<br />

following conceptual structure:<br />

to its high gas barrier properties, this<br />

biopolymer can be used in packaging that<br />

preserves aroma and effectively keeps<br />

out oxygen. In this packaging concept,<br />

an inner sealing layer - polyethylene,<br />

polybutylene succinate or polybutylene<br />

adipate terephthalate – is applied to the<br />

PLANTIC film and also acts as a moisture<br />

barrier. This production technologies used<br />

for this type of packaging are extrusion<br />

coating, lamination and extrusion<br />

lamination. The inner sealing layer and<br />

adhesive can easily be separated from the<br />

paper in the repulping process. Moreover,<br />

thanks to this biopolymer, the repulping<br />

yield is higher than e.g. a conventional PE<br />

layer because the fibers do not penetrate<br />

the PLANTIC film. Consequently, all of<br />

the paper fibers can be repulped without<br />

difficulty.<br />

Consumers and brand owners<br />

driving the trend<br />

Greater sustainability and circularity<br />

are an urgent issue for the whole of<br />

society and are being driven forward by<br />

legislators and consumers as well as brand<br />

owners and manufacturers. The objective<br />

is to find circular packaging solutions.<br />

Several major players in the food sector,<br />

from Danone and Mondelez to Nestlé<br />

and Unilever, have already published<br />

voluntary commitments or pledges. There<br />

is still plenty of scope to improve the<br />

sustainability of packaging for dry pet<br />

food. Intelligent use of modern polymers<br />

can help give popular paper-based<br />

packaging the necessary functionality –<br />

without compromising on sustainability.<br />

Weighing Technology Helps<br />

Petfood Line Efficiency<br />


An Ishida multihead weigher and<br />

checkweigher are helping to deliver<br />

effective speed, accuracy and quality<br />

control at leading Irish petfood<br />

manufacturer Irish Dog Foods. The<br />

machines are part of a complete turnkey<br />

line installation designed by Ishida’s Irish<br />

distributor SF Engineering.<br />

Irish Dog Foods, part of the Queally<br />

Group, produces premium dog treats and<br />

pet food. The company is a leading name<br />

in the pet foods market in Ireland and also<br />

exports to over 54 countries around the<br />

world in Europe, North America and Asia.<br />

The new line was required to process and<br />

pack pre-formed pet treats into doypacks.<br />

The speed and accuracy of the 14-head<br />

Ishida CCW-RVE-214W multihead weigher<br />

are helping the line to operate at 80<br />

packs per minute, exceeding the target<br />

originally set for the installation of 60<br />

ppm, and deliver an Overall Equipment<br />

Effectiveness (OEE) of 85%.<br />

Key to the CCW-RVE’s excellent weighing<br />

accuracy is its advanced combination<br />

calculation software. After the best<br />

weight combination has been calculated<br />

from the 14 weigh hoppers, it is double<br />

checked to ensure the discharge is as<br />

accurate as possible before the portion is<br />

released to the bagmaker.<br />

A customized feed system maintains<br />

a consistent feed of product to the<br />

multihead weigher. This works in<br />

conjunction with Ishida’s patented Pulse<br />

Width Modulation (PWM) technology that<br />

provides greater control of the infeed of<br />

the product both at the top of the weigher<br />

and to the weigh hoppers. The ability to<br />

automatically vary both the amplitude,<br />

time and frequency of vibration ensures<br />

a steady and consistent flow of product,<br />

maximizing speed and efficiency and<br />

eliminating the danger of overfill in the<br />

hoppers.<br />



TSCA 120/160<br />

The TSCA automatic sealing/clipping machine processes moderately<br />

priced flat roll stock film fully automatically into a clipped and filled tube.<br />

The ideal and cost-effective way to package your pet food.<br />

Automatic adjustment of clip pressure and displacer<br />

clip-pak ® benefits:<br />

In comparison to cans or trays clip-pak ® costs are<br />

30% less and packaging waste at the consumer end<br />

is reduced to a minimum.<br />

◉ Low packaging material cost<br />

◉ Low upstream transport & storage cost<br />

◉ Sustainable package due to low waste volume<br />

and minimized use of material<br />

Automatic monitoring of clip and die (RFID)<br />

After weighing, product is transferred<br />

to the pouch filling and sealing system.<br />

Packs are then passed through the<br />

Ishida DAGS-G-S015 checkweigher and<br />

metal detector combination to ensure<br />

product is the correct weight and free of<br />

metal contaminants. The checkweigher<br />

incorporates Ishida’s Anti-Floor Vibration<br />

(AFV) technology to maintain high<br />

weighing accuracy in environments<br />

susceptible to floor vibration. It also<br />

features the company’s Retail Reject<br />

Confirmation (RRC) software that checks<br />

and confirms that out-of-spec products<br />

or packs have been successfully removed<br />

from the line.<br />

“We have enjoyed a longstanding working<br />

partnership with Ishida,” commented<br />

Patricia Molloy, Marketing Manager of SF<br />

Engineering. “The company’s equipment<br />

is the best on the market, particularly<br />

in terms of its efficiency and reliability,<br />

and the CCW-RVE and DACS-G were the<br />

perfect choices to ensure we could deliver<br />

our targets for the line.”<br />

The new line has increased throughput<br />

by 75 percent. Operator requirement has<br />

been reduced by 60 percent and personnel<br />

reallocated to other manufacturing<br />

processes, thus improving overall facility<br />

productivity. These benefits have led to<br />

a reduced cost per pack, with Irish Dog<br />

Foods achieving a return on investment<br />

within 12 months of installation.<br />

“The line has been working well against<br />

agreed targets and is helping with<br />

our plans for further expansion and<br />

automation,” said Andrew Flynn, Irish Dog<br />

Foods’ Factory Manager. “The solution<br />

that SF Engineering and Ishida have<br />

delivered really is impressive.”<br />

Robotic Technology Answers<br />

Multiple Needs for PetFood<br />

a way to orient and load them was very<br />

important to the customer. With their<br />

robots, Cama was able to successfully<br />

orient the cups so they are all facing the<br />

same direction, with graphics aligned and<br />

in easy view on store shelves.<br />

The IF318 robotic loading system from<br />

Cama has been enhanced for a unique<br />

petfood packaging application with a US<br />

co-packer. Simmons Foods Inc. desired<br />

a system that offered flexibility to load<br />

varying product shapes, both cups and<br />

split cups of pet food. The cups are required<br />

to be loaded into plastic trays pre-inserted<br />

into cartons. Prior to loading the cups,<br />

Cama was challenged to align the cups<br />

to provide uniformity of cup graphics for<br />

shelf ready display. With varying flavors<br />

and product sizes, including small round<br />

(3.2 oz), regular round (4 oz) and a unique<br />

split cup design, there were a multitude of<br />

moving parts that required consolidation<br />

into one efficient solution at a rate of 600-<br />

700 cups per minute.<br />

Cama provided a solution that easily meets<br />

these needs and more. Their IF Monoblock<br />

system orients the cups, forms cases or<br />

cartons from blanks, inserts plastic trays<br />

into cases, loads cups into trays within<br />

the cases and closes the cases, all in one<br />

compact frame. As designed for Simmons,<br />

the system features four stations: case<br />

forming, tray depositing, product loading,<br />

and case closing.<br />

Unique needs of the project: the split<br />

cups are a fairly new product and finding<br />

Another unique challenge for this<br />

application was the tray handling: the<br />

plastic trays feature grooves to hold the<br />

required count of cups -- between 10 to<br />

36 cups per case -- on edge. The solution<br />

features robots to place the trays into four<br />

cases simultaneously, then place the cups<br />

into the slotted grooves in each tray.<br />

Cama Group’s IF Series Monoblock<br />

Loading Units are a unique combination<br />

of integrated packaging machines<br />

and robotic loading units that provide<br />

forming, loading and closing, or lidding,<br />

as well as added value such as reduced<br />

footprint, flexible size changes and high<br />

reliability. The system, equipped with<br />

Cama’s own, Y-shaped 2-axis robot, is<br />

designed to load various food and nonfood<br />

products into cases, trays, cartons,<br />

and other containers.<br />

Pet Food Packaged in an<br />

Efficient, Resource-saving and<br />

Eye-catching Way<br />

Heart-shaped EasyLid® Trays and Mono-PP Thermoformer Packaging for Snacks<br />

for dog snacks was created at Natural<br />

Greatness in three different formats. Two<br />

products are being sold in an attractively<br />

designed, triangular sleeve, the third<br />

is provided with a large label. All three<br />

pack formats guarantee optimal shelf life<br />

without sensory changes to the product,<br />

even after longer storage. Due to the<br />

required water vapor barrier, the flexible<br />

packs are made from mono-PP. "Thanks<br />

to the mono-PP, these single-material<br />

packs are completely recyclable after<br />

use, hence contributing to more resource<br />

conservation," explains Marcel Veenstra.<br />

Heart-shaped EasyLid® tray for cat snacks<br />

The worldwide growth in the number<br />

of pets during the pandemic years<br />

has brought higher demands to the<br />

international pet food market. Buying<br />

criteria, which we know from our own<br />

food items, now also often apply there:<br />

pet owners pay increased attention to<br />

the quality of ingredients, a high-class<br />

product presentation, and optimal shelf<br />

life. A well-known partner of the pet food<br />

industry is SEALPAC. With efficient, hightech<br />

traysealers and thermoformers, as<br />

well as the development of innovative<br />

packaging concepts, the company has<br />

firmly established itself in this segment.<br />

A significant category in pet food is snacks,<br />

such as dog or cat treats to reward the<br />

four-legged friends. In this competitive<br />

section, pet food manufacturers must be<br />

able to adapt quickly to the latest trends,<br />

so that they can always meet the current<br />

needs of their customers. Here, packaging<br />

plays a key role. This is where the highperformance<br />

machines from SEALPAC,<br />

which have been used successfully in<br />

the food industry for decades, are able<br />

to provide support. “Suppliers of pet<br />

food are increasingly relying on our<br />

machines and packaging expertise, both<br />

for tray-sealing and thermoforming. Our<br />

skills are particularly in demand in the<br />

snack portfolio, as two recent examples<br />

show," says Marcel Veenstra, Marketing &<br />

Communications Manager at SEALPAC.<br />

Flexible thermoformer: dog<br />

snacks in three packaging<br />

formats<br />

The manufacturer Natural Greatness from<br />

Valencia in Spain, which offers dog food<br />

without artificial additives, is particularly<br />

dependent on flexibility in production. It<br />

takes advantage of the use of SEALPAC’s<br />

RE20 thermoformer, which is suitable for<br />

various rigid and flexible film applications.<br />

Just like the other models within the REseries,<br />

this all-in-one thermoformer can<br />

handle multiple packaging solutions<br />

without significant effort: from flexible<br />

film vacuum, skin, shrink and MAP<br />

applications, up to modern solutions<br />

based on recyclable mono-materials or<br />

films with a high fiber content.<br />

In close cooperation with SEALPAC’s<br />

representative EMO S.A., new packaging<br />

With the SEALPAC RE20 thermoformer,<br />

the Spanish manufacturer has opted for a<br />

compact yet high-performance solution.<br />

It is equipped with the unique Rapid<br />

Air Forming system, which achieves an<br />

improved forming consistency, especially<br />

in the corners of the pack, whilst using<br />

shorter vacuum and ventilation times. This<br />

results in higher outputs, as well as the<br />

possibility to use thinner materials, but<br />

still creates stable and perfectly shaped<br />

packs. The required level of flexibility in<br />

the production of Natural Greatness is<br />

supported by the innovative quick tooling<br />

exchange system on the RE20, which<br />

enables frequent product changes with<br />

minimum downtime.<br />

Cat treats in reclosable, heartshaped<br />

tray<br />

The company Futternapf in Germany was<br />

looking for a particularly eye-catching<br />

solution for its cat snacks to meet modern<br />

packaging requirements. It turned to<br />

SEALPAC as its partner. A reclosable, heartshaped<br />

tray was developed for its socalled<br />

‘Knabberkissen’ (‘nibble pillows’),<br />

which immediately catches the eye on<br />

the crowded retail shelves due to its<br />

striking design. “Our innovative EasyLid®<br />

packaging system is used here, which we<br />

developed in cooperation with our Dutch<br />

partner Naber Plastics. It was already<br />

44<br />

Technology & Marketing


Innovative thermoforming concepts for pet food<br />

in use at various of our customers, but<br />

not yet in this unusual shape," as Marcel<br />

Veenstra explains.<br />

The EasyLid® solution combines a<br />

patented, injection-moulded tray,<br />

produced by Naber Plastics, with a unique<br />

tray-sealing technology by SEALPAC. The<br />

tray has a common sealing edge, as well<br />

as an additional ring. A peelable seal<br />

is applied to the regular sealing edge,<br />

whereas the additional ring is hermetically<br />

sealed in the same process. As such, upon<br />

opening the tray, the lid functionality is<br />

automatically activated.<br />

It means that the additional snap-on lid,<br />

common for this type of snack packaging,<br />

is no longer required. Also, there is no<br />

need to invest in a lidding system that<br />

requires extra space and more personnel<br />

in the factory.<br />

To increase awareness, Futternapf’s<br />

EasyLid® tray was given an attractive<br />

heart shape. It is available in two different<br />

heights and volumes (47mm high for<br />

70g and 87mm high for 140g). The trays<br />

are made of mono-PP, making them fully<br />

recyclable after use.<br />

Extraordinary geometry, full<br />

line control<br />

For any reliable packaging process, the<br />

trays must be able to run smoothly on the<br />

conveyor belt. In this case, we are dealing<br />

with an unusual shape that is difficult<br />

to guide, but it is not a problem on the<br />

SEALPAC traysealer. “We have developed<br />

our Walking Beam in-feed system<br />

for such cases,” says Marcel Veenstra.<br />

“Instead of a continuous conveyor belt,<br />

the well-enclosed trays are transported<br />

in fully controlled waves at a consistently<br />

high speed. It also guarantees the<br />

most accurate positioning of the trays<br />

underneath the automatic filling system,”<br />

he adds. Futternapf is using a SEALPAC A5<br />

traysealer. This model is ideal for getting<br />

started with fully automatic packaging, as<br />

it combines many of the properties of the<br />

larger SEALPAC traysealers in a particularly<br />

space-saving design.<br />

“These two examples show how eyecatching<br />

packaging solutions can be<br />

created for the pet food market, which<br />

Thermoformer packs for delicious dog treats<br />

combine efficient production with<br />

highest product quality and more<br />

resource conservation. SEALPAC and its<br />

local representatives are always happy to<br />

provide comprehensive advice on this,”<br />

emphasizes Marcel Veenstra.<br />

Young and Innovative: Interzoo<br />

2024 Encouraging Start-ups<br />

At Interzoo 2024, start-ups and innovators from the pet industry can profit from special conditions within the Start-up<br />

Area. The Fresh Ideas Stage will be the vibrant center of the Start-up Hall 3 combining product presentations, panels and<br />

the Fresh Ideas Contest.<br />

Interzoo, taking place in Nuremberg from<br />

7 to 10 May 2024, is the most important<br />

sales and communication platform for<br />

the international pet industry. Young<br />

companies and innovative ideas are a key<br />

driver for the industry and are therefore<br />

a special focus of the industry’s leading<br />

international trade fair. "New approaches<br />

to solutions in the areas of technology,<br />

sustainability, design and nutrition<br />

also play an important role in the pet<br />

industry. Accordingly, we are pleased to<br />

support start-ups and innovators in their<br />

participation in the most international<br />

trade fair for the pet industry with both<br />

attractive offers for exhibition stands and<br />

additional presentation opportunities at<br />

the Fresh Ideas Stage", says Dr Rowena<br />

Arzt, Head of Exhibitions at Interzoo<br />

organizer WZF.<br />

The Fresh Ideas Stage at Interzoo 2024 will<br />

give new business ideas in the pet sector<br />

a special presence: On all four days of the<br />

exhibition, companies can present trendsetting<br />

industry topics and products in<br />

short on-stage presentations. Based on<br />

last year's success, the Fresh Ideas Contest<br />

will also take place on the Friday of the<br />

exhibition, where innovative product<br />

ideas and services will compete for an<br />

award.<br />

Boost from the fresh ideas<br />

contest<br />

The first-placed start-ups of the premiere<br />

competition at last year’s Interzoo are<br />

already preparing their participation in<br />

Interzoo 2024. Contest winner Prombyx,<br />

specialized in the recycling of by-products<br />

of silk production, will take part with an<br />

individual stand in Start-up Hall 3. "The<br />

positive feedback during Interzoo has<br />

motivated and encouraged us. We are<br />

already looking forward to presenting our<br />

developments at the stand we won," says<br />

Managing Director Fabiola Neitzel. The<br />

second-placed start-up The Sustainable<br />

People, awarded for innovations around<br />

biodegradable dog waste bags, is<br />

enlarging its stand space by 25 percent.<br />

"This means more space to present our<br />

innovations in the field of recycling," says<br />

Sören Meissner, Marketing Manager of<br />

The Sustainable People. Both companies<br />

will be exhibiting at Interzoo 2024 in Hall<br />

3 in close proximity to the Fresh Ideas<br />

Stage.<br />

Funding for German-based<br />

start-ups<br />

Through the "Young Innovators"<br />

funding programme of the Federal<br />

Ministry of Economics and Climate<br />

Action, 25 company founders and<br />

young entrepreneurs from Germany can<br />

benefit from financial and organizational<br />

support at the upcoming Interzoo if<br />

they exhibit on the community stand<br />

"Young Innovators". Since 2018, Interzoo<br />

has been one of the exhibitions selected<br />

by this support programme, which has<br />

already shown sustainable success in the<br />

pet industry and assists companies in<br />

their international market development.<br />

"The support programme was crucial for<br />

us as a small, new company to enable<br />

us to participate in Interzoo 2022 and<br />

thus establish some interesting business<br />

relationships," says Patrick Weifels,<br />

Managing Director of PETvision GmbH,<br />

which produces multifunctional cat<br />

furniture.<br />

"The funded participation in the fair was<br />

an excellent showcase for us," explains<br />

Gema Aparicio, one of the founders of<br />

Eat Small. After two participations in the<br />

funded community stand with 12 sqm<br />

each, the pet food start-up will present<br />

its new insect-based products for the<br />

first time on its own 95 sqm stand space<br />

at Interzoo 2024 - a true Interzoo success<br />

story.<br />

Offers for international startups<br />

In order to also support newcomers with<br />

company headquarters outside Germany,<br />

Interzoo offers an attractive service<br />

package as part of the International Startup<br />

Area. This includes a specially designed<br />

presentation area on the prominently<br />

positioned community stand as well as<br />

selected marketing services that also<br />

enable smaller companies to increase<br />

their communicative reach. At the last<br />

Interzoo, 31 companies from 15 countries<br />

benefited from this offer. "Information<br />

and exchange about innovative<br />

products, new contacts and new business<br />

relationships, plus the very special startup<br />

feeling at the community stands and<br />

on the Fresh Ideas Stage: Interzoo 2024 is<br />

the perfect platform to enter the global<br />

pet industry," summarizes Dr Arzt.<br />

We Mourn the Loss of<br />

our Friend and Partner<br />

For decades Edouard has been the representative of PetFood<br />

PRO and other journals of the Dr. Harnisch publishing house<br />

in France.<br />

Born in Lille in 1937, married to Marie-Christine since 1977, he<br />

had two children, Benjamin, *1980, and Constance, *1982. In<br />

2022 he became the happy grandfather of his first grandchild.<br />

He had been taught the German language and culture by<br />

his father, a medical doctor. His first internship took him to<br />

Leica in Wetzlar, where he developed his passion for Leica and<br />

photography.<br />

Edouard Costemend<br />

For 28 years he worked for Gustav Elm, an advertising agency<br />

in Paris, which represented, among others, the magazine<br />

DER SPIEGEL in France. Since 1993 he has been working<br />

independently with his company AD PRESSE International,<br />

since 2000 exclusively for Dr. Harnisch Verlag. His son Benjamin<br />

has meanwhile succeeded him as area representative for<br />

France.<br />

In addition to his professional activities, Mr Costemend was<br />

an umpire at the French Open Tennis Championships at<br />

Roland Garros. Furthermore, he was characterized by lively<br />

cultural and political interests.<br />

Edouard Costemend was a noble, impressive man; he was<br />

trusted and held in high esteem everywhere. His integrity was<br />

a benchmark for all his colleagues. At the same time Edouard<br />

could be very funny and had a warm sense of humor. He was<br />

a wonderful host whenever we met in Paris and he loved<br />

showing the team different special places, away from the<br />

more tourist areas.<br />

We lose a valued friend and good partner and will miss him<br />

greatly.<br />

Our sympathy goes to his family, Marie-Christine, Benjamin<br />

and Constance.<br />

The Vet‘s Corner<br />

Interview with Dr. Gilch,<br />

specialist veterinary practice<br />

Dr. Constanze Gilch<br />

Dr. Constanze Gilch<br />

Dr. Constanze Gilch runs a specialist veterinary practice in Postbauer-Heng, Germany. The range of services<br />

includes ophthalmology, dermatology, surgery, internal medicine and dentistry.<br />

What is high-quality pet food in<br />

your opinion?<br />

The term "high-quality" has changed<br />

considerably in recent years. Every pet<br />

owner understands it differently. In my<br />

opinion, high-quality pet food consists<br />

of good ingredients without too many<br />

additives. Because many of these<br />

additives are not really necessary and<br />

you often don't know how many of them<br />

are actually included. What may be good<br />

for us humans is not necessarily good<br />

for an animal. High quality pet food<br />

should contain the actual ingredient<br />

in good quality. It is important that<br />

the food covers the individual needs<br />

of carbohydrates, proteins, fats and all<br />

necessary minerals and vitamins of the<br />

respective animal.<br />

Does it have to be organic?<br />

Yes, for me personally it does. After all I<br />

do not only want my pet to be well, but<br />

also that the animal I feed it had a nice<br />

life.<br />

What does "complete" nutrition<br />

mean for pets?<br />

A food is complete if it can meet an<br />

animal's entire requirement for the<br />

nutrients it needs. It is important to<br />

distinguish between complete feed<br />

and supplementary feed. Complete<br />

food offers all necessary ingredients in a<br />

balanced relation. Possibly the support<br />

of a nutritionist can be useful.<br />

What do you mean by "speciesappropriate"<br />

pet food?<br />

A pet food is species-appropriate if<br />

it provides what is similar to a food<br />

found in the wild. With a vegan diet<br />

of a pet, however, it could become<br />

difficult, because this can lead to serious<br />

deficiency symptoms. A vegan diet may<br />

be temporarily necessary as an exclusion<br />

diet for severe allergies, for example to a<br />

specific protein. However, it is important<br />

to replace the vitamin B12. If you<br />

prepare the food yourself, you should<br />

always have the ration calculated by a<br />

professional.<br />

What developments have you<br />

observed in the field of pet<br />

food in recent years?<br />

In the past 20 years, two main trends<br />

have been visible. On the one hand, a<br />

grain-free diet has become established,<br />

since grain was sometimes used as a<br />

cheap filler in pet food. However, grainfree<br />

diets can cause various diseases,<br />

such as heart disease, which are not<br />

curable. Of course, this also depends on<br />

the particular animal: a dog obviously<br />

needs grain in certain amounts, whereas<br />

a cat does not. This was not even known<br />

until a few years ago. While veterinary<br />

medicine is already further along here<br />

and has recognized the benefits of<br />

substances from the grain for dogs,<br />

this knowledge has unfortunately not<br />

yet made its way to pet owners and<br />

pet stores. On the other hand, there is<br />

a trend toward rare protein sources to<br />

give pets something special, such as<br />

horse meat, kangaroo, water buffalo or<br />

insects. Here I clearly see a tendency<br />

towards humanization. And this trend<br />

is not necessarily good for the animal,<br />

because more and more often patients<br />

come to the practice with the suspicion<br />

of a feed intolerance, which have already<br />

received all "rare protein sources" at the<br />

age of 1 or 2 years. So there is no room at<br />

all for a food change to something they<br />

are guaranteed not to react to yet. This<br />

becomes difficult at the latest when all<br />

attempts with alternative carbohydrate<br />

and protein sources have already been<br />

exhausted at the beginning of a therapy.<br />

Rare protein sources should therefore<br />

not be offered from the outset.<br />

What do you think about<br />

BARFING (to feed a natural raw<br />

diet)?<br />

There are patients who cannot tolerate<br />

maximum processed food and readymade<br />

products. If the food is actually<br />

self-prepared, it is a good thing. After<br />

all, there is a good intention behind it if<br />

you want to know what is in it. BARFING<br />

with prepared products in the form<br />

of a "ready-made sausage", however, I<br />

consider dangerous, because there are<br />

many bacteria and fecal germs in it. Here<br />

it is always important to have a good<br />

source of supply of the ingredients used.<br />

Publications<br />

What should be fed in certain<br />

intervals?<br />

In a balanced and complete diet with<br />

complete food, no other nutrients are<br />

necessary, except for dental care.<br />

What food can I use to support<br />

an animal's dental health?<br />

Dental care cannot be achieved 100 %<br />

through food alone. Chewing articles, for<br />

example from cattle scalp, can be given in<br />

between. However, these do not replace<br />

the toothbrush! It is still necessary to<br />

brush the teeth additionally. At least<br />

every 24 to 48 hours plaque should be<br />

removed.<br />

How to prevent allergies with<br />

appropriate pet food?<br />

Already during pregnancy, a high<br />

quality diet is important. The mother<br />

should get probiotics for a healthy<br />

intestinal flora, as well as the puppies<br />

in the first months, this leads to greater<br />

resistance. Thus, after 4 years, more than<br />

80 % less allergies were observed in<br />

dogs. The protective effect through the<br />

microbiome was effective throughout<br />

their entire lives. Good hygiene can<br />

prevent gastrointestinal infections and<br />

intolerances. During the first 6 to 12<br />

months, antibiotics should be given only<br />

in extreme emergencies.<br />

What would you like to see from<br />

pet food manufacturers?<br />

The ingredients should be declared<br />

more clearly and not just somewhere<br />

hidden in the small print. The declaration<br />

"With chicken" I consider misleading,<br />

because only 4 % of it has to be in the pet<br />

food, while with the designation "Pure<br />

meat" exclusively chicken is contained. I<br />

would also like to see that not as many<br />

ingredients as possible are added to<br />

pet food, such as herbs, berries, and<br />

the like, just because we consider such<br />

ingredients to be healthy. Instead, we<br />

should ask ourselves: Do we really need<br />

this? What actually needs to be in it?<br />

Thank you, Dr. Gilch, for your<br />

insights and your infectious<br />

love amd care for pets.<br />

Premiere of the Pet Food Zone at<br />

Anuga FoodTec 2024<br />

New presentation platform for the pet food industry<br />

Anuga FoodTec - the International Suppliers Fair for the Food and Beverage Industry,<br />

is expanding its exhibition space to include a special section for the pet food industry.<br />

The Pet Food Zone will celebrate its debut at the next Anuga FoodTec, which is being<br />

staged in Cologne from 19.-22.03.2024. It serves as an ideal presentation platform<br />

for all suppliers from this spectrum of offers of the trade fair and places the focus on<br />

innovative ideas and products.<br />

In this way, the trade fair is reacting to<br />

the high demand from the industry:<br />

The market for pet food is experiencing<br />

continual growth and recently recorded an<br />

annual growth rate of over three percent.<br />

With a turnover of around 30 billion Euros<br />

in the year 2022 in Europe alone this<br />

was reason enough to offer the pet food<br />

market an area of its own. "Many of the<br />

Anuga FoodTec exhibitors already offer<br />

a wide selection of solutions for the food<br />

industry that can be equally implemented<br />

for the pet food industry. On installing the<br />

Pet Food Zone we are creating a central<br />

information hub that enables the visitors<br />

to inform themselves in a fast and simple<br />

process about the solutions offered<br />

for their sector," said Matthias Schlüter,<br />

Director of Anuga FoodTec.<br />

Under focus: Innovative<br />

technologies<br />

The requirements for the production,<br />

quality, packaging, storage and transport<br />

of pet food are demanding and are on a par<br />

with the high standards of the food and<br />

beverage industry. The manufacturers of<br />

pet food are thus increasingly interested<br />

in innovative technologies that make their<br />

production even more competitive and<br />

cost-effective. Anuga FoodTec already<br />

attracted over 3,000 decision-makers from<br />

the pet food industry in the year 2022.<br />

Both established and aspiring companies<br />

have the opportunity to present their<br />

products and services at Anuga FoodTec<br />

2024: From novel pet foods through to<br />

innovative technologies and sustainable<br />

concepts such as environmentally-friendly<br />

packaging solutions.<br />

Organized by Koelnmesse, Anuga FoodTec<br />

is placing the emphasis on the key theme<br />

Responsibility. The professional and<br />

industry sponsor is the DLG, the German<br />

Agricultural Society.<br />

New exclusive media partner<br />

The trade magazine PetFood PRO is the<br />

new and exclusive media partner of the<br />

Pet Food Zone.<br />

The English-language magazine belongs<br />

to the publishing house, Dr. Harnisch<br />

Verlag, which, launched in 2019, is the<br />

international magazine for executives<br />

and specialists of the pet food industry.<br />

"The cooperation with PetFood PRO and<br />

the Dr. Harnisch publishing house as a<br />

long-standing and reliable partner of<br />

both the food and beverage industry<br />

underlines the new relevance of the pet<br />

food industry at Anuga FoodTec," is how<br />

Matthias Schlüter, Director of Anuga<br />

FoodTec, explained the cooperation.<br />

Benno Keller, publisher and President of<br />

the publishing house also emphasized<br />

the importance: "We have known<br />

Anuga FoodTec since its inception and<br />

are delighted to be part of the further<br />

development of the trade fair. Almost<br />

every family has a pet and the quality of its<br />

food is becoming increasingly important.<br />

The exhibitors of Anuga FoodTec play an<br />

essential role here."<br />
