【Process flow】

The vacuum freeze-drying process of general pet food is as follows: fresh pet food raw materials - pretreatment (raw material selection - cleaning - draining - cutting) - pre-freezing - quick freezing - vacuum freeze drying - packaging.

Freeze dryer in new pet food freeze-drying processing method:

1. Prepare raw materials, meat pieces and grains and by-products including cornmeal, wheat flour, wheat bran and rice, etc.;
