Basic criteria for selecting a bagging system<br />
Walter Kersting Haver & Boecker<br />
To achieve an efficient packaging system, you have to harmonize<br />
the characteristics of your product with the bag<br />
type and the bagging technology. In this article, the author<br />
draws on his experience in the petrochemical industries<br />
to outline the criteria to consider when selecting a bagging<br />
system. Special attention is given to the form-fill-seal<br />
bagging method.<br />
Criterios básicos para la selección de un sistema<br />
de embolsado<br />
Para lograr un sistema de embolsado eficiente es nece-<br />
The global picture of bulk packaging is a very complex one,<br />
and industrial bagging practice varies greatly from country<br />
to country. In China, for example, 95 percent of petrochemical<br />
products are packaged in 25-kilogram bags. In the<br />
USA, only 5 percent of petrochemicals are packaged in bags<br />
that size.<br />
Using the petrochemical industry as a springboard for<br />
discussion, this article provides guidelines for deciding<br />
which technique is right for packaging your bulk solid mate-<br />
sario armonizar las características de su producto con el<br />
tipo de bolsa y la tecnología usadas. El autor de este<br />
artículo recurre a su experiencia en la industria de petroquímicos<br />
para resumir los criterios que deben tomarse en<br />
consideración al seleccionar un sistema de embolsado.<br />
Critères de base pour la sélection d’un système<br />
d’ensachage<br />
Pour obtenir un système d’emballage efficace, il faut accorder<br />
les caractéristiques du produit avec le type de sac<br />
et la technique d’ensachage. Dans cet article, l’auteur, met<br />
à profit son expérience dans l’industrie pétrochimique,<br />
pour présenter dans ses grandes lignes les critères de<br />
sélection d’un système d’ensachage.<br />
Grundlegende Kriterien für die Auswahl einer<br />
Absackanlage<br />
Die Eigenschaften Ihres Produkts müssen auf die Art der<br />
Säcke und die Absacktechnologie abgestimmt sein, um<br />
ein leistungsstarkes Verpackungssystem zu erzielen. Der<br />
Verfasser dieses Artikels beruft sich auf seine Erfahrungen<br />
in der petrochemischen Industrie, um die Kriterien<br />
zur Auswahl einer Absackanlage zu erläutern.<br />
rials. Warehousing and shipment strategies are also discussed.<br />
Even if you don’t handle petrochemicals, the information<br />
will help you establish efficient packaging operations<br />
for packaging free-flowing pellets and granules.<br />
Available packages include flexible intermediate bulk<br />
containers (FIBCs, also called bulk bags), rigid IBCs, and<br />
smaller flexible bags. The smaller flexible bags are usually<br />
the open-mouth (also called open-top) variety. Form-fill-seal<br />
(FFS) bags offer several advantages within this class of bags.
Packaging materials<br />
Operations that package products in 25-kilogram bags<br />
mostly use ready-made open-mouth polyethylene (PE) bags,<br />

Baffles make FIBCs more stable and easier<br />
to stack.<br />

woven polypropylene (PP) bags, or side-gusseted tube-stock.<br />
(The tube-stock can only be used with FFS equipment.)<br />
The criteria for selecting the correct bag are<br />
Strength. The required strength of the bag material depends<br />
on the number of times the bag must be transferred before<br />
it reaches the final destination. Woven PP bags are<br />
particularly strong.<br />
Cost. Cost usually corresponds to the value of the product.<br />
A commodity product may call for an inexpensive bag,<br />
while a high-value additive may call for a more expensive bag<br />
with good printabilty for labeling.<br />
Availability. Availability varies from region to region,<br />
usually according to local preferences.<br />
Protection. Protection refers to the ability of the bag to<br />
withstand exposure to moisture, ultraviolet (UV) radiation,<br />
temperature extremes, and contaminants.<br />
De-aeration. Locking air inside the bag can lead to burst<br />
bags. Assuming the contents of the bag are not hazardous and<br />
do not react chemically when exposed to air, the bag should<br />
be able to “breathe.”
12 SEPTEMBER 2008 | PBEI<br />
Palletizing. How easy are the bags to load on a pallet and<br />
how stable are they once palletized?<br />
Discharge. Discharging the contents of the bags quickly,<br />
easily, cleanly, and safely corresponds to bag type, but it also<br />
depends on the discharge methods your customers use.<br />
Printing. The bag must give you enough room to print<br />
all the necessary information on it.<br />
Reuse. Sometimes bags are returned for reuse and sometimes<br />
they can be recycled. Woven PP bags are best-suited for<br />
reuse.<br />
Batch inclusive capability. With the correct packaging<br />
materials, the bag and its contents can enter a process cham-<br />

ber, such as a reaction vessel, together. This eliminates packaging<br />
waste and reduces costs.<br />
FIBCs. In some applications, such as packaging engineering<br />
plastics, the use of FIBCs is increasing. They are an attractive<br />
alternative to smaller bags because they<br />
Are easy to discharge using a vacuum pneumatic conveyor<br />
Use less packaging material than smaller bags to hold a<br />
given quantity of material<br />
Remain stable when stacked<br />
Fit snuggly in standard 6- and 12-meter-long containers<br />
Can be reused<br />
See Figure 1.<br />
IBCs. Rigid IBCs are a good alternative<br />
when the contents require<br />
strong protection or a highly stable,<br />
stackable package that only a rigid<br />
container can provide.<br />
Ready-made bags. PE and woven<br />
PP bags are simple packages and easy<br />
to transport manually. You can also<br />
use the weight of the bag’s contents<br />
(typically 25 kilograms) as the dosing<br />
unit and thus eliminate the need<br />
for batch weighing. Furthermore,<br />
bag-filling operations can be highly<br />
automated to maximize capacity.<br />
FFS bags. In the petrochemical<br />
industry, FFS bags, made from tubestock,<br />
continue to gain acceptance and<br />
may now dominate. Of all the 25-kilogram<br />
bags available, FFS bags—made<br />
from 120-micron-thick, side-gusseted<br />
material—are the most economical.<br />
Typically, they are co-extruded in two<br />
layers. Usually, 80 percent is low-density<br />
polyethylene (LDPE), and 20 percent<br />
is linear low-density polyethylene<br />
(LLDPE). Some FFS bags are made<br />
with 50 percent of each material. Coextruded<br />
bags withstand temperatures<br />
to 93°C, so they are well suited to handling<br />
petrochemicals that must be<br />
packaged while they are still warm, a<br />
development that is common due to<br />
changes in production methods.<br />
FFS technology<br />
When evaluating whether an<br />
FFS bagging system is right for your<br />
operation, consider<br />
Bagging rate (number of bags per<br />
hour)
Weight accuracy<br />
Dust control<br />
Densification of the bagged product<br />
Energy consumption<br />
Product sensitivity to mechanical<br />
impact<br />
Ease of operation and maintenance<br />
Automatic adjustment when product<br />
changes<br />
Flexibility to accept changes in<br />
product characteristics<br />
Ease of cleaning<br />
In many cases, one FFS machine<br />
can meet all these criteria. Figure 2<br />
shows a typical FFS machine.<br />
In operation, FFS machines perform<br />
several functions. The first step is<br />
sealing the tube-stock to form the cor-<br />

Corner seals on gusseted bags<br />

ners of the bag. Corner seals improve<br />
your ability to stack the bags, and they<br />
are strong because the two-layer film<br />
joins into four layers at the gusset. See<br />
Figure 3. The corner seals also minimize<br />
the amount of product remaining in the<br />
bag after discharge at the end-user’s site.<br />
After sealing the corners, the machine<br />
cuts the tube-stock to the correct<br />
length. Bag length depends on the target<br />
weight of the material and on the<br />
material’s bulk density. You can adjust<br />
the bag length during operation. In the<br />
next two steps, the machine perforates<br />
the film to provide for de-aeration and<br />
welds the bag bottom shut. Then a vacuum<br />
device opens the bag top and the<br />
machine fills the bag to the correct<br />
weight. Finally, hot pinch bars weld the<br />
top shut.
14 SEPTEMBER 2008 | PBEI<br />
There are two classes of FFS machines: gross-weight and<br />
net-weight. In gross-weight systems, the bag is weighed on a<br />
live scale as it’s filled. In net-weight systems, the material<br />
passes through a weigh-hopper before entering the bag.<br />
Gross-weight machines are more compact than net-weight<br />
machines. They also handle products more gently and are<br />
commonly used to bag high-value materials, such as engineered<br />
resins, where capacity is low and a vapor barrier is required.<br />
Gross-weight machines are also well suited for<br />
applications that require frequent product changes and thus<br />
frequent cleaning. Outputs of FFS machines are 100 to 1,800<br />
bags per hour.<br />
FFS options. One option is to affix nozzles to the bagging<br />
machine to clean material contact areas automatically. Another<br />
option is an air evacuation system that removes air from the bag<br />
and shrinks the gaps between particles. There is also a gussetfolding<br />
device on the market that enables you to transform flat,<br />
tubular film into gusseted film. See Figure 4. The advantage:<br />
Rolls can hold double the amount of tube-stock compared with<br />
gusseted film. Finally, an optional embossing device reduces the<br />
tendency of bags to slip around on the pallet.<br />

Layout of the packaging operation<br />
In general, FFS bagging lines (including palletizing and<br />
loading operations) operate at 65 to 75 percent of the design<br />
capacity of the FFS machines. In operations that handle a single<br />
material, the FFS machine is stationary and material enters<br />
the packaging line directly from a nearby silo. Operations that<br />
package a large percentage of product in FIBCs or do a lot of<br />
bulk load-out to trucks, will usually select stationary bagging<br />
equipment. That is because FFS quantities are smaller and it is<br />
more practical to bring the product to the bagging machine<br />
instead of moving the bagging machine.<br />
Logistics terminals, however, handle many materials, and<br />
flexibility is key. Thus, they are better served by mobile FFS<br />
machines. See Figure 5. Instead of transporting the material to<br />
the FFS machine from a silo, workers move the FFS machines<br />
to the storage silos. In this way, the product in each silo is<br />
bagged, loaded into silo trucks, or placed in FIBCs on demand—without<br />
the complication of long-range scheduling.<br />
The two drawbacks to mobile FFS machines are higher labor<br />
costs and higher equipment costs compared with stationary<br />
machines. The higher equipment cost doesn’t fall only on the
Figure 6<br />

PBEI | SEPTEMBER 2008 15<br />
machine’s mobility. You must<br />
also factor in other equipment,<br />
such as belt conveyors<br />
mounted on casters, that link<br />
the FFS machine to a stationary<br />
palletizer.<br />
The FFS machines move<br />
with the assistance of air pads<br />
or motor-driven wheels. Machines<br />
with motor-driven<br />
wheels are more expensive<br />
than machines with air pads,<br />
but workers like the motordriven<br />
machines better because<br />
a joystick offers a simple<br />
way to control movement.<br />
Investing in a mobile system<br />
to fill FIBCs is also a good<br />
idea to serve customers who<br />
prefer these large containers.<br />
See Figure 6. FIBC loaders fill<br />
as many as 60 containers per<br />
hour, depending on the con-<br />

tainer size and the target weight. In the petrochemical industry,<br />
FIBCs typically weigh 500 to 1,500 kilograms after filling. The<br />
size of the FIBCs differs according to the product handled, and<br />
the different sizes mean that only semi-automatic operation is<br />
possible. As a result, FIBCs must be placed on the filling spout<br />
by hand. After that, operation is automatic, except final sealing<br />
of the filling spout.<br />
If you need the FIBC loader to fill 30 containers per hour<br />
or more, select a net-weight loader instead of a gross-weight<br />
loader. The net-weight unit will allow you to separate the<br />
weighing and filling operations and thus operate faster. The<br />
FIBC loader may include a vibrator to densify the contents<br />
and stabilize the container.<br />
Warehousing<br />
The highest labor costs of the entire operation are found<br />
in the dispatch step—loading the trucks and supplying the<br />
correct paperwork. Dispatch also consumes a good amount of<br />
time. In Europe, the trends are to install shelves for storing<br />

trends without careful study, because many companies that<br />
use these approaches have not achieved the success that they<br />
expected. Both systems are expensive to install, and they are<br />
slowed by frequent maintenance.<br />
Right now, the most efficient logistic and inventory control<br />
technology is placing the palletized bags on the floor. You<br />
can stack up to three FIBCs atop one another. (You will probably<br />
need pallet supports.) Whatever storage method you select,<br />
efficient warehousing requires a computer-based<br />
inventory-tracking system and a forklift guidance system.<br />
A computer-based inventory system controls all material<br />
flow through the warehouse, including the silo loading and<br />
unloading system. See Figure 7. It also provides:<br />

Statistics<br />
The inventory system can be linked to a “vehicle site access<br />
system” to optimize vehicle flow within the plant. By controlling<br />
traffic within the plant, the system reduces waiting times<br />
when loading the trucks and preparing documents. Transponder<br />
cards ensure that the trucks are loaded with the correct product.<br />
The system also measures the weight of the truck to see<br />
whether it’s empty or full. Compared with the shelf-storage systems<br />
that have become popular in Europe, vehicle site access<br />
systems are more efficient when you calculate the transfer capacity<br />
per employee. They also reduce human error.<br />
Conclusion<br />
Although packaging systems differ from region to region<br />
and country to country, high efficiency is paramount<br />
everywhere. Each application requires its own specific solution,<br />
but efficiency depends on a good, complete analysis of<br />

CASE<br />
HISTORY<br />
EWOS produces fish feed at plants<br />
in Norway, Chile, Canada, and<br />
Scotland. It also operates several<br />
fish farms, where it raises salmon, trout,<br />
and other species. The company is<br />
known in the aquaculture industry for<br />
its Dynamic brands of fish feed. It has<br />
about 800 workers worldwide.<br />
The EWOS plant in Westfield,<br />
Scotland, makes a full range of feeds on<br />
two process lines, each following the<br />
same basic steps. A weigh-batching system<br />
meters the ingredients, then<br />
grinders reduce the particle sizes. After<br />
blending and mixing, the moist feed<br />
passes through an extruder. Next comes<br />
drying, vacuum coating with oil, and<br />
bagging.<br />
The feeds vary in size from crumbles<br />
of 0.3 millimeters to pellets of 25 millimeters.<br />
They also contain different<br />
amounts of oil, nutrients, pigments, and<br />
other ingredients to suit the fish species,<br />
its growth stage, its habitat, and other<br />
factors. As a result of these variables, the<br />
Westfield plant offers 1,000 different<br />
feeds.<br />
Flexibility is key<br />
With so many different products,<br />
“We’ve got to be very flexible,” said<br />
Mark Wright, process engineering manager.<br />
Each new production run can<br />
require stopping the process to clean<br />
and re-fit the extruder, as well as to clean<br />
the dryer and cooler. A run might be as<br />
small as 2.5 tons, Wright said. In that<br />
case, “the extruder is up for cleaning<br />
even before the product is through the<br />
dryer. But we’ve gotten pretty good at<br />
FFS bagging adds<br />
flexibility at feed plant<br />
FORM-FILL-SEAL BAGGING SYSTEM HANDLES OUTPUT FROM TWO<br />
PROCESS LINES.<br />
The net weigher, installed above the FFS bagging machine, can make 600 25-kilogram weighments per hour.<br />
it, pretty good at standardizing the routine.”<br />
Automation and an experienced<br />
staff minimize product re-work, he said.<br />
Each of the two process lines has an<br />
extruder. One can produce 9 tons per<br />
hour, and the other can produce 5 tons<br />
per hour. Together, the two process lines<br />
can make about 80,000 tons per year.<br />
Actual production fluctuates with the<br />
slow and busy periods of the fish-farm<br />
business. “If it’s stormy weather in<br />
January or February, for instance, production<br />
starts dropping off because the<br />
farmers can’t get to the fish,” Wright
Using one FFS system to handle the production of<br />
two lines made it possible to reduce the number of<br />
workers running the bagging operation. It also means<br />
EWOS can stop buying ready-made bags. The savings<br />
on bags alone will pay for the cost of installing the<br />
complete FFS system within 6 years.<br />
The FFS bagging machine makes bags from polyethylene tube stock, eliminating the need for ready-made bags.<br />
said. “We might go from 6,500 to 3,000<br />
tons in a month.”<br />
At the moment, production is about<br />
50,000 tons per year. Most of the feed<br />
goes to customers within the UK and<br />
Ireland. Some also goes to Norway, and<br />
about 25 percent of production goes to<br />
EWOS-owned fish farms.<br />
Improving packaging<br />
EWOS ships about 55 percent of its<br />
feed in 25-kilogram bags. The rest is<br />
shipped in 500-kilogram and 1,000-kilogram<br />
bulk bags. For years, each process<br />
line had its own semi-automatic packing<br />
machine to fill 25-kilogram bags using<br />
ready-made, open-mouth bags. In 2001,<br />
PBEI | SEPTEMBER 2008 21<br />
however, EWOS managers decided to<br />
replace the bagging machine dedicated<br />
to the lower-capacity line.<br />
“It was outdated, like over 15 years<br />
old,” Wright said. “It was worn out, and<br />
you couldn’t get parts.” The capacity<br />
was also limited. “The capacity was OK<br />
for the smaller extruder, but it wouldn’t<br />
have been for the other,” Wright said.<br />
“The old machine wasn’t flexible<br />
enough for two lines.”<br />
In evaluating the options, Wright<br />
found that a form-fill-seal (FFS) bagging<br />
system had enough capacity for both<br />
process lines. Using one packaging line<br />
instead of two held the potential for<br />
reducing labor costs, because workers<br />
would only need to tend one operation,<br />
not two. EWOS would keep the other,<br />
larger bagging machine as a fail-safe.<br />
An FFS bagging system could also<br />
reduce the cost of bags. Instead of buying<br />
ready-made bags, EWOS could buy<br />
large, pre-printed reels of plastic tube<br />
stock and feed it through the FFS<br />
machine. The main difficulty in using a<br />
single packaging system, Wright said,<br />
was transferring the feed from the larger<br />
process line to the new FFS system,<br />
which would be on the other side of the<br />
plant.<br />
New system<br />
After contacting three equipment<br />
suppliers about the job, Wright selected<br />
a proposal from Richard Simon Limited,<br />
a business unit of Canada-based Premier<br />
Tech Systems, located in Nottingham,<br />
UK. The proposal called for a packaging<br />
system that used the supplier’s<br />
UBM net weigher, a vertical FFS<br />
machine, a robotic palletizer, a stretchwrapper,<br />
and a pallet conveyor. The proposal<br />
also specified a dense-phase pneumatic<br />
conveyor to move fish feed from<br />
the larger process line to the FFS system.<br />
Richard Simon Limited would act as<br />
project manager.<br />
The proposal “wasn’t the cheapest,”<br />
Wright said, but it appealed to him for<br />
other reasons. “We had used some of<br />
their equipment, so we knew what we<br />
were getting. We also knew their field

to determine the properties<br />
of the solids that are being used. The<br />
key properties of the bulk solid are those<br />
which relate to how it flows in the vessel.<br />
Constraints on the vessel design are also<br />
considered. Once the material’s flow<br />
properties are known, one could calculate<br />
the type of flow pattern<br />
which would occur in a<br />
vessel having a particular<br />
geometry and size. One of<br />
two basic flow patterns would<br />
exist: funnel flow and mass flow.<br />
Based on material flow property<br />
data generated, engineers at Jenike &<br />
Johanson would develop the functional<br />
design of the purge column. The design<br />
would provide a more uniform residence<br />
time of the solids & distribution of<br />
purge gas with no adverse effects on<br />
the flowing solids, such as local<br />
fluidization, short-circuiting of the<br />
bed, or possibly rate limitations, thus<br />
improving product quality.<br />

An articulated-arm, robotic palletizer places finished bags on a pallet at rates as high as 30 tons per hour.<br />
engineer, so that had a lot to do with it.<br />
I wouldn’t give someone the job just<br />
because they’re the cheapest. When<br />
you’re talking about hundreds of thousands<br />
of pounds, it comes down to who<br />
you trust.” Startup was in August 2001.<br />
A programmable logic controller<br />
(PLC) runs the entire operation. To<br />
begin, feed flows from packing bins to<br />
the net-weigher, which includes a twospeed<br />
belt feeder, a stream-depth regulator,<br />
and a catch-gate. It uses just one<br />
load cell beneath a cantilevered weighing<br />
pan. Anti-vibration mountings<br />
secure the entire net-weighing assembly,<br />
which weighs the feed and releases it, 25<br />
kilograms at a time, to the filling tube<br />
of the FFS machine.<br />
The FFS machine uses single-web<br />
film that it forms into square-bottom<br />
bags and then places on to the filling<br />
tube. After gravity filling, the bag is<br />
heat-sealed, cut from the tube stock,<br />
and conveyed from the FFS mac7hine.<br />
All contact parts are stainless steel. The<br />
FFS machine also includes a motorized<br />
film reel and an encoder that controls<br />
bag length.<br />
Next, an articulated-arm, robotic<br />
palletizer places the bag on a pallet<br />
using its servomotor drive and plastic<br />
bag-gripper. It can accommodate two<br />
sizes of pallets and three sizes of bags.<br />
Once the robot fills the pallet, the<br />
stretch-wrapper consolidates the load,<br />
and the packaged feed moves to the<br />
shipping area. The palletizer handles as<br />
much at 30 tons per hour, equal to<br />
1,200 25-kilogram bags. That is double<br />
the capacity of the new FFS machine,<br />
and enables EWOS to use the same palletizer<br />
should the company install a second<br />
FFS machine in the future.<br />
The pneumatic conveyor was something<br />
of an innovation for EWOS. Oil in<br />
fish feed could have made the feeds difficult<br />
to convey. “That’s something we were<br />
aware of,” Wright said, “so we got our<br />
most oily feed and we did a test on it to<br />
make sure it was going to work OK.” The<br />
test results were good and are reflected in<br />
the system’s performance, Wright said.
“It’s worked out perfect. It’s nice and<br />
gentle. It doesn’t create any dust and<br />
we’ve never had a blockage or anything<br />
in the system,” he said. “No one has ever<br />
done pneumatic conveying with fish<br />
feed, so I wanted to be the first.”<br />
The conveyor operates gently enough<br />
that no sieving is required to remove<br />
fines downstream. That’s done before<br />
the feed enters the conveyor. “We go<br />
straight to the packing line,” Wright<br />
said. The maximum amount of dust<br />
allowed in the bag is 0.2 percent by<br />
weight. “If there were any problem, we<br />
would have complaints. I’ve never had a<br />
customer complaint for any material<br />
coming off that line.”<br />
Conclusion<br />
Using one FFS system to handle the<br />
production of two lines made it possible<br />
to reduce the number of workers running<br />
the bagging operation. It also<br />
means that EWOS can stop buying<br />
ready-made bags. The savings on bags<br />
alone will pay for the cost of installing<br />
the complete FFS system within 6 years,<br />
Wright said.<br />
Its reliability is another plus. “I like<br />
to buy equipment without a lot of<br />
maintenance in it,” Wright said.<br />
“Conventional packaging lines cost<br />
quite a bit of money to keep them<br />
going, but we’ve not spent any money<br />
on the new machine, so that’s good.”<br />
Mainly, the FFS machine—coupled<br />
with the pneumatic conveyor—gives<br />
EWOS operational flexibility. “It was a<br />
gamble” to install the pneumatic conveyor,<br />
Wright said. “But now, we have<br />
the option: We can send everything to<br />
that one new FFS machine or keep running<br />
stuff through the remaining packing<br />
line. It’s good to have options and<br />
flexibility. That’s the way I wanted it.”<br />

CASE<br />
HISTORY<br />
Thai Luxe Enterprises, Samutsong -<br />
khram, Thailand, began as an exporter<br />
of frozen seafood. In 1987, the<br />
company began manufacturing shrimp<br />
feed, and in 1993 it added extruded fish<br />
feed. The feeds are mostly used to raise<br />
catfish, tilapia, and carp. Over the last 5<br />
years, feed sales have increased 20 to 25<br />
percent annually.<br />
Thomas Wilson manages the fish<br />
feed factory and has helped increase sales<br />
since joining Thai Luxe in 1997 as a feed<br />
formulator. At that time, sales of fish<br />
feed had little effect on the company’s<br />
bottom line, because the shrimp-feed<br />
business was main source of income, he<br />
said. Even so, Thai Luxe managers<br />
wanted the fish-feed business to show a<br />
profit, and thus named Wilson factory<br />
manager in 1998.<br />
Factory reaches the limit<br />
Before Wilson arrived, annual sales<br />
totaled about 3 percent of the Thai market<br />
for fish feed. Then, thanks to Wilson’s<br />
reputation as a formulator, sales<br />
increased by 19 percent in 1997. The<br />
next year, with Wilson as manager, sales<br />
rose another 19 percent. “I doubled<br />
some parts of the process line, so production<br />
could continue even if we had<br />
breakdowns, and focused on product<br />
quality and consistency,” Wilson said.<br />
By 1999, sales were up almost 60 percent,<br />
and the single process line reached<br />
its limit. “We ran out of capacity in the<br />
third quarter that year,” Wilson said. It<br />
was time to upgrade the process.<br />
First, the company doubled the size<br />
of its extruder to 6 metric tons per hour.<br />
Conveyor dryers<br />
increase capacity, ensure<br />
quality at Thai Luxe<br />
FISH FEED MANUFACTURER HOOKS UP TWO NEW DRYERS.<br />
A belt conveyor transfers moist extruded feed to a chute leading to the first of two conveyor dryers.<br />
It then upgraded the other equipment<br />
to handle the increased output, adding<br />
two pulverizing systems, a higher-capacity<br />
mixing line, a new cooler, and<br />
more bin storage. As part of the extruder<br />
upgrade, Wilson added a dual-loop<br />
graphic controller. It interfaces with the<br />
metering devices and valves that Thai<br />
Luxe workers use to control the flow of<br />
steam and moisture into the pre-conditioner<br />
and the extruder. The controller<br />
reduced moisture variation in the finished<br />
feed by half, because it “simplifies<br />
the job that the dryers have to do,” Wilson<br />
said.<br />
Next came the two-pass conveyor<br />
dryer, which had been a problem for<br />
some time. “We had a Thai-made copy<br />
of an American double-deck dryer,”<br />
Wilson said. It had required “frequent<br />
maintenance after only 4 years of use,<br />
and a complete replacement of the floor<br />
and coils after only 6 years,” he said. “It<br />
was not hard to convince company executives<br />
that, while the locally made dryer<br />
had cost only half the amount of an imported<br />
dryer in 1993, it had not been a<br />
good buy.”<br />
Because of the recent overhaul,<br />
how ever, “I was loath to take it out and<br />
replace it,” Wilson said. “My decision at<br />
the time was to increase drying capacity<br />
by adding a small dryer downstream of<br />
this dryer.” He consulted three suppliers<br />
of drying equipment. One of them<br />
was the Thailand-based agent of Aero -<br />
glide, located in Raleigh, NC USA. “I<br />
had read about [their] dryers before<br />
coming to Thailand, and knew they<br />
were very good”<br />
Small dryer bridges capacity gap<br />
“I was immediately impressed by<br />
[the supplier’s] technical approach,”
Working together, the dryers handle up to 7,500<br />
kilograms of feed per hour. That equals 900 to 1,000<br />
kilograms of moisture evaporated per hour.<br />
A view of the feed entering one of the conveyor dryers. The dryers use steam heat and remove up to 1,000 kilograms of<br />
water per hour.<br />
Wilson said. “They sent their local<br />
agent to evaluate the drying capacity of<br />
my existing dryer. Then, when we met<br />
face to face with their sales team, they<br />
worked out a mass-balance equation to<br />
determine our needs. Then we looked at<br />
the existing equipment to find out what<br />
constraints were placed on the design.”<br />
The constraints included little space<br />
to the side or overhead of the existing<br />
dryer. In addition, the width of the drying<br />
bed had to match that of the existing<br />
dryer. “It took a while but we finally got<br />
a workable design,” Wilson said. He<br />
also considered using a vertical dryer,<br />
but he found it too difficult to install. “I<br />
had never comprehended the full<br />
amount of space required for a complete<br />
vertical dryer installation. I just didn’t<br />
have the room.”<br />
Instead, he selected a single-pass,<br />
horizontal conveyor dryer from Aero -<br />
glide. Installed in March 2000, the<br />
dryer increased capacity enough to meet<br />
demand through 2001. But by the third<br />
quarter of 2001 the factory again ran out<br />
of capacity because of another 60 percent<br />
jump in sales at the end of that year.<br />
By that time, the small, single-pass<br />
dryer—intended to handle half of the<br />
drying task—was in fact doing threefourths<br />
of the drying, Wilson said, because<br />
of the poor performance of the<br />
Thai-made double-deck dryer. “We realized<br />
that the original double-deck<br />
dryer was limiting our production capacity<br />
for basically two reasons,” Wilson<br />
said. “First, the two dryers were unable<br />
to dry more than 5 metric tons per hour.<br />
Second, since the old dryer was working<br />
beyond its capacity, with overloaded and<br />
uneven beds, moisture uniformity was<br />
quite poor.” That raised concerns about<br />
mold formation.<br />
“The risk of molding is very high in<br />
our tropical climate,” Wilson said. “But<br />
PBEI | SEPTEMBER 2008 27<br />
by managing the process and using<br />
mold inhibitors, our difficulties were<br />
largely invisible to our customers.” But<br />
those measures didn’t provide a longterm<br />
answer to the capacity shortage<br />
and quality concerns. “We realized that<br />
if the extruder was to be utilized to its<br />
full capacity, the inefficient dryer would<br />
have to be replaced,” Wilson said. In<br />
mid-2001, Thai Luxe again contacted<br />
the US-based supplier and asked about<br />
buying a second dryer.<br />
Time for another dryer<br />
“We saw that the first single-pass<br />
dryer worked well with few problems,”<br />
Wilson said. “We could see that the<br />
dryer, at less than half the size, was efficiently<br />
doing more than half the work.<br />
Nevertheless, we had to be convinced”<br />
that another dryer would improve the<br />
operation. Convincing the Thai Luxe<br />
managers meant evaluating the drying<br />
process and calculating the return on the<br />
investment in a new dryer. Thai Luxe<br />
paid for the evaluation, but would be reimbursed<br />
the expense if it bought a dryer.<br />
According to the performance evaluation,<br />
the single-pass dryer was using<br />
26 percent less steam per kilogram of<br />
water evaporated compared to the double-deck<br />
dryer that Thai Luxe intended<br />
to replace. A cost-benefit analysis<br />
(using average values that Wilson supplied)<br />
showed that a new dryer would<br />
pay for itself in 1.3 years. Wilson then<br />
re-calculated the analysis using new,<br />
detailed information. “It was apparent<br />
that if the dryer allowed us to increase<br />
production by 20 percent this year, the<br />
dryer would achieve payback in only 1<br />
year,” Wilson said. “This is quite fast by<br />
normal standards. I estimated that<br />
boiler fuel costs per ton of feed produced<br />
could be reduced by 7.7 percent<br />
if I took out the old dryer and replaced<br />
it with a new dryer as efficient as the<br />
one we had already installed.” The<br />
company installed the new double-pass<br />
dryer in May 2002.<br />
The fast payback was tied to the<br />
dryer’s design. “The difference between
28 SEPTEMBER 2008 | PBEI<br />
SEE US AT POWTECH BOOTH # 6-153<br />
the old ‘all-up’ airflow design<br />
and a modern design<br />
with ‘up-down’ airflow<br />
was remarkable,” Wilson<br />
said. The new dryer,<br />
which was about half the<br />
size of the old doubledeck<br />
dryer, was also more<br />
efficient. Still, the main<br />
benefit of the new dryer was removing<br />
the drying bottleneck to increase production<br />
and improving moisture uniformity,<br />
he said.<br />
The new unit has two drying zones<br />
and a drying bed 3 meters wide. The<br />
intake module was customized to fit<br />
the existing space and positioned to<br />
accommodate the existing upstream<br />
and down stream flow of product.<br />
Thus, as feed exits the double-pass<br />
dryer, it flows into a chute that is just as<br />
wide as the drying bed. The chute leads<br />
to the floor below, where the singlepass<br />
dryer moves the feed through its<br />
two drying zones. Working together,<br />
the dryers handle up to 7,500 kilograms<br />
of feed per hour. That equals 900<br />
to 1,000 kilograms of moisture evaporated<br />
per hour.<br />
Each dryer uses the same type of<br />
graphic controller as the extruder. One<br />
controller manages the temperatures in<br />
both zones of each dryer. “We set the<br />
temperature, and we can see the temperature<br />
rise and fall in real time,” Wilson<br />
said. “With automated tem perature<br />
control, the dryers can adjust internal<br />
rising or falling temperatures that are<br />
caused by differences in loading rates or<br />
changing moisture levels in the incoming<br />
product.”<br />
Company forecasts strong<br />
growth<br />
So far in 2002, fish-feed sales are<br />
up 34 percent over last year, and Thai<br />
Luxe is close to attaining a 15 percent<br />
market share in Thailand. As the company<br />
builds its reputation for making<br />
industry-leading feeds in terms of<br />
quality and performance, Wilson ex-<br />
pects sales will<br />
con tinue to rise<br />
by 20 to 25 percent<br />
annually.<br />
Thus it’s possible<br />
that within 1 or 2<br />
years, Thai Luxe<br />
will have to invest<br />
in a new production<br />
line, he said. At that time, he<br />
said, he will look for suppliers that<br />
excel in their specialties, as he did when<br />
selecting the supplier of the conveyor<br />
dryers.<br />
Some of the fish feeds produced at Thai<br />
Luxe.<br />
“I believe that the best machine for<br />
any particular job is usually going to<br />
come from a company that specializes<br />
in one product, and therefore invests in<br />
engineering excellence and research and<br />
development programs that lead to new<br />
advancements for that product,” he<br />
said. “This kind of company can help<br />
you to solve problems or develop customized<br />
products to meet your particular<br />
needs.” PBEI<br />
