Product introduction

When the screw press is running, the treated oil enters the press chamber from the hopper. The material embryo is pushed in continuously by the screw to press. Because the embryo is in motion in the chamber of the oil press, under the condition of high pressure in the chamber, there is a great friction resistance between the embryo and the screw, and between the embryo and the chamber, which can cause friction between the embryo and the micro material, resulting in relative motion. 

On the other hand, because the root diameter of the screw press is gradually increased and the pitch is gradually reduced, when the screw press rotates, the hard material embryo of the screw press can be pushed forward and turned outward. At the same time, the material layer near the surface of the screw press also rotates with the screw press shaft. In this way, each embryo particle in the pressing chamber does not move in the same direction at the same speed, but there is relative motion between the particles. 

Screw oil press machine

The heat generated by friction meets the necessary heat for the operation of the oil press, which helps to promote the thermal denaturation of the protein in the material embryo, destroy the colloid, increase the plasticity, and reduce the viscosity. Some oil is easy to be separated out, so the oil yield of the oil press is improved, and the oil in the material is pressed out by oil pressure, and flows out from the circular and strip gaps.
