Peanut oil press 
    There are screw oil presses and hydraulic oil presses for peanut oil presses. Screw oil presses are one of the advanced oil press products. Spiral peanut oil press is mainly divided into two parts: hydraulic and squeeze cavity. It works by squeezing out the oil from the peanuts under high pressure. Then filtered through vacuum negative pressure. It will be cleaner after the oil comes out. The screw press uses mechanical pressure to extrude the oil part of the oil under high pressure. So as to achieve the purpose of squeezing oil.
    The working principle of peanut oil press. When the oil press is running, the processed oil enters the press chamber from the hopper. By pressing the screw, the material embryo is continuously pushed inward for pressing.        Because the material embryo is carried out in a moving state in the press chamber of the oil press, under the condition of high pressure in the press chamber, a large frictional resistance is generated between the material embryo and the snail, the material embryo and the press chamber Can cause friction between material and micro-materials, causing relative movement
The diameter of the root orchard of the peanut press is gradually thickened, and the pitch is gradually reduced. Therefore, when the screw is rotated, the thread can be pushed forward and turned outward, and it is close to the surface of the screw. The material layer also rotates with the press shaft. In this way, each preform particle in the press chamber does not move at the same speed and in the same direction, but there is relative movement between the particles. The heat generated by the friction also meets the necessary heat for the operation of the oil pressing process, which helps to promote the thermal denaturation of the protein in the material embryo, destroys the colloid, increases the plasticity, and also reduces the viscosity and easy to precipitate oil. The oil output rate of the oil press is improved, so that the oil in the material is squeezed out and flows out from the gap between the row and the row.
