Mechanical energy is converted into heat energy

- Apr 08, 2018 -

     It belongs to a device for processing expanded foods, such as rice, corn, soybeans, and wheat in daily life. Its main working principle is that the mechanical energy is converted into heat energy, and the food is squeezed and cooked by the heat generated when the machine rotates. The most obvious feature of the puffed food is its large size.

     Extruders are versatile and widely used in feed, food, and industrial applications. They are based on extruders (dry, wet, single or twin screw). Here we describe one or a group of functions during the bulking process. These features are:

     Cohesion: During the expansion process, food or feed ingredients can be tightly combined and condense into discrete pieces.

     Degassing: Bubbled foods or feed ingredients are degassed during the bulking process.

     Dehydration: In the general food or feed puffing process, the water content will lose 4%-7% on the original basis.

     Expansion: Extruder operating conditions and configuration can control the density (eg, sinking or buoyancy) of pet feeds and aquafeeds.

     Gelation: Puffing can gelatinize starch (from a variety of sources, such as tubers or grains) during the processing of food or pet feed.

     Grinding: Raw materials can be ground to a certain degree in the extruder during the processing of food or feed.

    Homogenization: The homogenization of the extruder changes the structure of the unattractive raw material to make it a more acceptable form.

     Mixing: During the expansion process, a variety of extruders are available for a wide variety of extruders, which allows the extruder to produce the desired amount of mixing.

     Pasteurized Sterilization and Sterilization: Raw materials can be pasteurized or sterilized with bulking technology during the food or feed expansion process.
