Rubber Machine/Pin-Barrel Cold Feed Rubber Extruder

Basic Info:

   The cat/dog food produced by this production line is characterized by high protein content, complete nutrition . And microelements can be added to promote rapid growth of pet.Different pet food can be made by changing the ancillary machines by moulds. The production line can also be used in manufacturing other pet food ,such as bird food ,fish food.

Working Principle:
The extruder has a pair of screws and sleeves that have the function of mixing and twisting. After the raw material enters the expansion chamber, the material is squeezed, rubbed, sheared, etc. between the screw sleeves, and the internal pressure is continuously increased, up to 4Mpa, and the temperature is continuously rising, up to 140 degrees Celsius. During the period of 3-7s, the temperature and pressure increase sharply, and the structure of the material changes, which further gelatinizes the starch, denatures the protein, destroys the crude fiber, and kills harmful bacteria such as Salmonella. The high temperature and high pressure materials come out from the discharge port, and the pressure is suddenly released in an instant, and the water is partially flashed. After cooling, the material is loose and porous, and the expanded material is in the form of agglomerates, flocs or coarse chips.
