Basic Functions Of Extruder

The wide range of functions of the extruder makes it widely used in feed, food and industrial fields. Based on the extruder (dry method, wet method, single screw or twin screw), we introduce one or a group of functions in the process of expansion , These functions are:

Cohesion: In the process of puffing, food or feed ingredients can be tightly combined to condense into discrete small pieces.

Degassing effect: The food or feed material containing bubbles will be removed during the puffing process.

Dehydration: In the expansion 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 of pet feed and aquatic feed (such as sinkability or floatability).

Gelation: Puffed cooking can gelatinize starch (from various sources, such as tubers or grains) during the processing of food or pet feed.

Grinding effect: During the processing of food or feed, the raw materials can be ground to a certain degree in the extruder.

Homogenization: The homogenization of the extruder changes the structure of unattractive raw materials and makes it a more acceptable form.

Mixing effect: In the process of puffing treatment, various extruders have a variety of screws to choose from, which can make the extruder produce the desired mixing amount.

Pasteurized sterilization and sterilization: In the process of puffing food or feed, raw materials can be pasteurized or sterilized using puffing technology.
