array of viscosities. "A piece of equipment designed to
be versatile, like a Vemag extruder, will have the ability
to swap pumping elements or front-end attachments to
allow for new products," Reiser's McIsaac says.
The Vemag extruder, offered by Reiser, features a
powerful positive displacement double-screw pump that
provides high portioning accuracy while transporting
product gently without degradation. There are a number
of double-screw configurations offered which allows pet
food processors to produce a variety of products with
one machine. "A Vemag using a double-screw to produce a high volume of dense product can also be used to



produce a highly accurate stream of liquid product with
a simple change of the double-screw pumping element,"

Maintained for the long haul
A thorough and routine sanitation and maintenance
program can keep an extruder running efficiently for
