Do you know about dog food extruders?

Extruders are widely used in feed, food, and industry due to their diverse functions. Based on extruders (dry, wet, single screw or twin screw), we introduce one or a group of functions in the extrusion process. These functions are:
Coagulation: During the extrusion process, food or feed raw materials can be tightly combined and condensed into discrete small pieces.
Degassing: Bubbles will be removed from food or feed raw materials containing bubbles during the extrusion process.
Dehydration: During the extrusion process of general food or feed, the water content will lose 4%-7% on the original basis.

Expansion: The operating conditions and configuration of the extruder can control the density (such as sinking or floating) of pet feed and aquatic feed.
Gelation: Extrusion cooking can gelatinize starch (from various sources, such as tubers or grains) during the processing of food or pet feed.
Grinding: During the processing of food or feed, the raw materials can be ground to a certain extent in the extruder.
Homogenization: The homogenization of the extruder changes the structure of unattractive raw materials into a more acceptable form.
Mixing: During the extrusion process, various extruders have a variety of screws to choose from, which can make the extruder produce the desired mixing amount.
Pasteurization and sterilization: During the extrusion process of food or feed, the raw materials can be pasteurized or sterilized using extrusion technology.
