The feed pellet machine is based on the principle of circular motion. The template and the pressure roller are treated with alloy steel. The main shaft and the flat die drive the pressure roller to rotate under the action of friction. The material is gelatinized at high temperature between the pressure roller and the template, and the protein is solidified and denatured. It is discharged from the mold hole under the pressure roller extrusion, and the particles are sent out of the machine through the material throwing tray, models that improve economic efficiency.
