Twin screw extruder is more advantageous than single screw extruder

Twin screw extruder is more advantageous than single screw extruder.

Compare with single screw extruder, twin screw extruder could add fat twice as single screw in pet food material. So the grease could reach more than 20%. So this not only improves the quality of the formula, but also slows down the wear and tear of the spare parts and reduces the production cost. Single screw extruder  can't do it. Fat content is restricted in single screw extruder, because if the fat content is too high, will cause the extrusion machine fluctuate violently, and thus lead to the instability of product quality. Once the fat content in material is too high, it will cause the material to stick and the machine cannot run. .In addition, the twin screw extruder can complete the change of raw material in 30 s, which can be used for color recognition and the product that allows multi-color mixture to be processed directly in the extruder.
