of nutraceuticals in
pet food has also
fostered extrusion
technology innovation because the
process must protect
the integrity of sensitive ingredients and
perform reliably.

innovation for food
safety is a valve used
to divert extrudate
that has not reached
appropriate parameters before it enters
the die plate.

Reliability and consistency are two crucial hallmarks
of the extrusion process. "The ability to retain and
slow cook (relatively speaking) the product in a gentle
manner is a key to making repeatable quality highmeat kibble," Tramp says. "And consistency of items
such as recipe homogenization, barrel pressures, barrel fill levels and incoming product temps can greatly
affect the consistency and quality of the final product."
Preconditioners play a vital role in achieving
product homogeny before extrudate enters the
extruder. "Preconditioners are used to 'pre-process'
the extrudate by mixing ingredients with the
addition of heat and moisture. They initiate
starch gelatinization before the product enters the
extruder which allows the process inside the
extruder barrel to perform more complex processing
tasks," Brisset explains. Preconditioning offers many
benefits, including increased consistency and quality
of the product throughout the entire process, energy
savings, and greater flexibility and control over
operating parameters regardless of formulation.
Specifically, for high-meat formulations, Brisset says
the fresh meat is mainly injected in the preconditioner
as it contains a high level of water (up to 70%) and
therefore needs longer residence time for mixing with
dry ingredients and steam injection to bring it to the

proper temperature. Preconditioning allows extra
processing time (3 to 4 minutes) compared to the typical residence time in the extruder (10 to 20 seconds)
where the cooking is completed.
Clextral's Preconditioner+ includes Advanced Filling
Control (AFC), a screw device inside the mixing chamber that intensifies processes, and a new steam injection design that facilitates better product absorption. It
also includes a reversible conveyance screw, allowing it
to be completely emptied for cleaning.
Similarly, Extru-Tech's Aseptic Dual Preconditioner
(ADP) allows operators to incorporate low steam pressure and adjust product retention time, resulting in
starch gelatinization levels up to 60% formula dependent, temperatures over 90 C (194 F), high meat addition and low energy consumption, Henry explains. The
stainless-steel preconditioner also has a sanitary design.
Henry says Extru-Tech's ADP is one key advancement,
along with energy management features, higher extruder
shaft speeds and more horsepower, that has allowed singlescrew processes to deliver on complicated formulas, such
as high-meat.
High-meat inclusions aren't the only trend driving
innovation in extrusion equipment. "Demand is focusing on premium, high-quality products that combine
ideal nutrition with other health-oriented properties,"
