The machine is divided into several models, and there are two functions. One is that there is no kneading function, the other is a kneading function, but the difference between material and size is larger, and the output is also a little more. The difference between the ordinary model and the upgraded stainless steel model is that the normal pressure roller and the face cutter of the pressure roller and the face cutter are made of carbon steel, while the upgraded stainless steel is made of stainless steel.
