Functions Of The Extruder

The variety of functions of the extruder makes it widely used in the fields of feed, food and industry. Based on the extruder (dry method, wet method, single screw or twin screw), we introduce one or a group of functions in the extrusion process. , these functions are:

Agglomeration: In the process of puffing, food or feed ingredients can be tightly combined and agglomerated into discrete pieces.
Degassing: Food or feed ingredients that contain air bubbles will be degassed during the expansion process.
Dehydration: During the expansion of general food or feed, the water content will lose 4 percent -7 percent on the original basis.
Expansion: The operating conditions and configuration of the extruder can control the density (such as sinking or floating) of pet food and aquatic feed.
Gelatinization: Expansion cooking can gelatinize starches (from various sources, such as tubers or grains) during the processing of food or pet feed.
Grinding: Raw materials can be ground to a certain extent in an extruder during the processing of food or feed.
Homogenization: The homogenization of the extruder changes the structure of an unattractive material into a more acceptable form.
Mixing action: During the extruding process, various extruders have a variety of screws to choose from, which can make the extruder produce the desired mixing amount.
Pasteur sterilization and sterilization: In the process of food or feed extrusion, the raw materials can be pasteurized or sterilized by extrusion technology.
