Shearing and homogenizing screw extrusion device suitable for edible mushroom cultivation base material and application of shearing and homogenizing screw extrusion device

The shearing and homogenizing screw extrusion device comprises a feeding machine and a screw extruder, a discharging opening of the feeding machine is communicated with a feeding opening of the screw extruder, and the screw extruder comprises a main motor, an extrusion screw, a sleeve and a heating temperature control system. The device further comprises a plurality of shearing cylinders, stirring blocks and homogenizing rings, wherein the shearing cylinders are mounted on the extrusion screw rod and rotate along with the extrusion screw rod; and the shearing cylinder, the stirring block and the homogenizing ring replace part of the spiral to form a set of composite extrusion screw rod. The screw extruder solves the technical problems of slow temperature rise and non-uniform temperature rise when a common screw extruder is used for processing an edible fungus cultivation base material, realizes rapid and uniform temperature rise of the material, improves the uniform state of the extruded material, and realize
