PET Food Processing - June 2019 - 46

"Another key feature for production of high meat
kibble is the important ability to measure and control
process parameters such as moisture, water activity
and product density through on-line sensors."

Brisset says. "One area that has sparked innovation is
nutraceuticals that deliver nutrients, vitamins or medications in a pet-friendly format. These new products
can gain high profit margins, but require processing
that is reliable, adaptive and scalable, and protects the
integrity of sensitive ingredients in their recipes."
To support the inclusion of nutraceuticals in pet
foods and treats, Clextral's Evolum+ twin-screw
extruders include a temperature control feature that
continuously monitors and automatically adjusts production parameters, according to Brisset.
Another formulation trend includes exotic protein
sources. "Interestingly, many of the novel
ingredients that have recently been trending in
the market (such as algae, fungi and insect meals)
are able to be handled by the most recent generations of extrusion technology with a few
appropriate adjustments," Rokey explains.

The product diversion feature allows for startup
and shutdown waste to be diverted from the final die,
which keeps the die area from becoming contaminated
and protects downstream processes and product integrity, which has become increasingly crucial in the age
of FSMA. Startup temperatures are monitored by an
integrated probe system. The BPV also features a shutdown die relief setting, which reduces extruder pressure built up behind the die for operator safety, Tramp
explains.
A similar development is the Energy Management
Valve (EMV) from Extru-Tech. "The Energy Management Valve (EMV) is one of the newest offerings
from Extru-Tech that completes food safety requirements," Henry says. "The EMV system prohibits under-processed product from entering the die and will
automatically divert in the event of CCP violations."
Extru-Tech's EMV also eliminates the dead zone where
residual product can harbor pathogens.

Food safety
One of the main reasons for processors to replace
an extrusion system entirely is to meet the evolving pet food safety standards set by the Food Safety
Modernization Act (FSMA) in 2011. Sanitary designs
and screw innovation in extrusion technology have allowed processors to stay on top of market trends while
adhering to FSMA standards.
"Today's extruders are equipped with state-ofthe-art controls and many have self-learning systems that monitor production and adjust to changes
automatically to ensure product quality and consistency," Brisset says. "They have hygienic designs
and features to simplify maintenance and cleaning,
which translates into reduced downtime and
lower costs for the processor."
A key development in food safety for extrusion is
the addition of a valve to divert product at a CCP that
has not reached the appropriate temperature or quality
standards.
Wenger's Back Pressure Valve (BPV) controls the
restriction on the discharge of the extruder and allows for product diversion. By changing the restriction
at the discharge of the extruder during operation, the
product density can be varied by up to 25% without
changing the screw configuration or the final die.

Careful consideration
Processors looking to add capabilities for complex formulas should consider throughput, consistency and
process control, says Rokey. Although extrusion equipment has the capacity to produce an ever-broadening
range of products, it may not be in a processor's best
interest to take on all these formats.
"Often times, we would not suggest that one extrusion system does all three categories though. This is
due to capacity restrictions that commonly occur in
the packaging area when producing long goods and the
fact that optimum ROIs for the other two categories are
often better realized at throughputs above those used
for long good production," Tramp says.
When considering new equipment or formulations,
extrusion technology experts can be a processor's best
friend. "By relying on the expertise of their suppliers
when developing high protein products, pet food processors can learn and understand how to manage different ingredients, so they do not become a production
challenge," Brisset concludes.
As processors look to develop into niche areas of
pet foods and treats, durable extrusion systems, cutting-edge technology and knowledgable suppliers are
prepared to overcome any formulation challenge. PFP
