hydration and heating are the more consistent of a result
can be planned for and achieved," Martinez-Kawas says.
"Without a preconditioner, the attainable rates would be
as much as 15 to 20% lower and thus margins would be
much less."
Beyond the process benefits on product quality, the
material going into the extruder from a preconditioner
is already moist and therefore less abrasive, reducing
wear on the extruder parts, Lavocat says. "Variablespeed devices make it possible to adjust the residence
time as required and thus adapt the equipment to different types of recipes," Lovacat adds. "The efficient precooking enables a reduction of the shear and the torque
used in the extruder, which also is beneficial in reducing
the wear of the screws and barrels."
Realizing the full benefit of a preconditioner for the

wide variety of formulas required in today's pet food
market can take some fine tuning. The target temperature for the product leaving the preconditioner and the
desired moisture content depends heavily on each recipe
and the type of kibble being produced.
"The best way to evaluate [a preconditioner] is to
test it associated with an extruder in real conditions,"
Lavocat says. "To operate a preconditioner at maximum
efficiency, the right balance between mixing/agitation,
residence time, filling ratio and thermal energy has to
be found." Lavocat reiterates that preconditioners are an
important piece of equipment for the pet food extrusion
process. "A fine and efficient optimization of the preconditioning operating conditions requires some time and
effort but is well worth the benefits it can bring to the
process and product quality," he says.

The first criteria a preconditioner must meet
is the ability to maximize
mixing, heating and
hydration uniformly.
