How is pet food prepared in an extruder?
Extruder is common in the production of pet food and pellets and fish feed pellets, single screw and double screw extruder. Its function is that the material enters the extruder and moves in the form of an axial flow under the screw pressure.
At the same time, due to the mechanical friction between the screw and the material, the material particles are severely compressed, crushed and cut.
