Experts in Spray Technology

ENSURE FOOD SAFETY,
INCREASE PRODUCTIVITY
AND REDUCE CHEMICAL USE
SYSTEM OVERVIEW:
Meat and poultry processors all have a common goal —
to ensure the highest level of food safety possible while
minimizing production costs. AutoJet ® Antimicrobial Spray
Systems help processors achieve these goals by eliminating
slower, more expensive post-pasteurization techniques.
AutoJet Antimicrobial Spray Systems apply a predetermined
volume of antimicrobial agent onto each product or into
each package. An AutoJet spray controller monitors liquid
pressure and flow from PulsaJet ® automatic spray nozzles
to ensure the proper volume of antimicrobial is delivered to
each product.
Used successfully with several commercially-available
topical antimicrobials, the efficacy of this technology has
been established by the USDA/ARS.
The systems have a proven track record of effectively
controlling pathogens including E. coli, Salmonella and
Listeria monocytogenes while reducing operating costs
for processors. Using this technology, some customers
have eliminated the need for lactates, diacetates and other
internal antimicrobials entirely.
AutoJet Antimicrobial Spray Systems can be incorporated
into existing HACCP plans. An optional auto-refill/ratio panel
is available to continuously monitor the fluid level in the
pressure tank and trigger a refill cycle when necessary. The
auto-refill/ratio panel also dilutes concentrated antimicrobial
to the proper ratio for application.

BENEFITS:
• Closed-loop control ensures precise application of antimicrobial
for consistent performance and minimal waste
• Different shot sizes and timing intervals can be
pre-programmed for automatic batch changes
• Pressure tank is easy to assemble/disassemble and clean
• Easy integration in existing product lines
• Unattended operation – alarms notify workers if intervention
is required
• Optional auto-refill/ratio panel triggers tank refill and
maintains proper antimicrobial concentration
SYSTEM MODULES:
Application requirements determine the actual
configuration of an AutoJet ® Antimicrobial Spray System.
Key components include PulsaJet ® electric spray nozzles
with FDA-compliant finishes, an Allen-Bradley PLC and a
pressure pot.
IDEAL FOR:
• Bagged whole muscle products
• Hot dogs, links and formed products
• Fresh meats – subprimals and trim
• Packaged poultry products
• Sliced meat and poultry products

Antimicrobials are sprayed into the vacuum packages
before sealing. Vacuum-sealing of the packages
distributes the antimicrobial evenly around the product.
The efficacy of this SLIC ® (Sprayed Lethality in Container)
process has been established by the USDA/ARS.
Conveyorized meat and poultry products are sprayed
with multiple PulsaJet nozzles within an enclosed
spray station, typically located before injectors/
tenderizers or immediately prior to packaging.

SLICED PRODUCTS
Meat trim pieces inside tumblers, mixers and blenders
are sprayed with multiple PulsaJet ® nozzles to ensure
even coating of all pieces before the grinding process.
Tests have shown consistent coverage throughout
ground meat packages using the AutoJet ® Antimicrobial
Spray System.
Integrated into the most advanced slicing systems on
the market and synchronized with blade movement, high
speed PulsaJet automatic spray nozzles apply precise
antimicrobial doses to each sliced product prior to
packaging. Additional antimicrobials are added to each
package to cover all surfaces of the stack.

RESULTS EXPERIENCED BY
PROCESSORS
OLD WORLD PROVISIONS: ANNUAL SAVINGS OF $300,000
Old World Provisions, a meat processor specializing in whole
muscle products and roll stock products, decided to use the
AutoJet ® Antimicrobial Spray System to reduce the expense
of the functional ingredients used as antimicrobial agents. A
single system is being used on a roll stock line and a bagger
operating at six packages per minute.
The outcome has exceeded expectations.
• The use of an antimicrobial agent that cost $0.025 to $0.030
per pound was eliminated. Lauric arginate diluted in a clarified
liquid smoke is now used at an application cost of just
$0.015 per pound
• Typical log reductions ranging from 1.8 to 2.8 for roll stock
and whole muscle products
• Product quality and shelf life have remained stable
• Product labels are clean
• The use of lower cost antimicrobials saves the company
$300,000 each year

JOHN MORRELL & CO.: ELIMINATED USE OF
LACTATES/DIACETATES
John Morrell & Co., a subsidiary of Smithfield Foods, Inc., is
the largest vertically integrated producer of processed meat
and fresh pork in the United States. Concerned about the flavor
of certain hams containing lactates/diacetates, the company
opted to treat them externally with lauric arginate using
an AutoJet ® Antimicrobial Spray System.
The results are impressive.
• Improved product flavor
• 1 to 2 log kill against Listeria monocytogenes
• The process is even more efficacious on products that
include other antimicrobials, such as a cured product containing
nitrite
• Product labels are clean
NORTH COUNTRY SMOKEHOUSE:
40% INCREASE IN SHELF LIFE, ALT-2 STATUS
ACHIEVED
North Country Smokehouse, a family-run smokehouse, has
been using the system on a wide variety of meat products.
The results include:
• An increase in product shelf life to 70 days from 45 to 50 – a
40% increase
• Achievement of ALT-2 status at a cost of $0.015 per pound
on products using a lauric arginate and liquid smoke flavor
antimicrobial
• Typical log reductions range from 2.3 for hams to 4.0 for
kielbasa
• Clean label on products maintained – lauric arginate is a
bacteriocide that is also considered a processing aid and
does not need to be labeled at the levels being used
