Preconditioning
What is preconditioning?
It may seem a simple question, but when
put to the test, many process managers are
unable to truly define preconditioning.
Here’s a definition that covers most of the bases:
Preconditioning is the formation of a
homogenous final product from a mixture
of two or more dissimilar raw materials, then
hydrating to particular moisture and precooking
for ease of extrusion processing, to provide a
uniform and consistent flow to the extruder.
