Do you know about dog food extruders?

The diverse functions of extruders make them widely used in feed, food and industry. 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 coagulated into discrete small pieces.
Degassing: Bubbles are 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.

Gelatinization: Extrusion cooking can gelatinize starch (from various sources, such as tubers or grains) during the processing of food or pet feed.
Grinding: The raw materials can be ground to a certain extent in the extruder during the processing of food or feed.

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.
Feed extruder is a single-screw extruder. It is mainly used for food extrusion, livestock and poultry feed or for extruding a single raw material. It can also be used as a pre-treatment of raw materials in the production of vegetable oils and drinking wine. Twin-screw extruders are mainly used for the production and processing of high-grade aquatic feed and pet feed, especially for the processing of highly viscous materials.
