The advantages of the screw press are: advanced design, reliable performance, simple operation and easy maintenance: its main characteristic is high oil yield. Compared with the old equipment, the normal oil yield can be increased by 2-3 percentage points. The average output of 100 kilograms of peanuts per kilogram can be more than 2-6 kilograms, and the annual economic benefit can be seen.
Screw oil press manufacturer: when the screw oil press is running, the treated oil enters the press chamber from the hopper. Through the spiral rotation, the material embryo is continuously pushed inward for pressing. Because the material embryo is in motion in the press chamber of the oil press, in the case of high-pressure press chamber, there will be great friction resistance between the material embryo and the press screw, and between the material embryo and the press chamber, resulting in friction between the material embryo and micro materials and relative motion.
On the other hand, as the root diameter of the screw gradually increases and the pitch gradually decreases, when the screw rotates, the screw can move forward and turn outward, and the material layer close to the surface of the screw also rotates with the shaft. In this way, each embryo particle in the press chamber does not move at the same speed, but in the same direction, and there is also relative movement between the particles. The heat generated by friction meets the heat required for the operation of the oil pressing process, helps to promote the thermal denaturation of proteins in embryos, destroy colloids, increase plasticity, reduce part of viscosity, and is easy to precipitate oil, so as to improve the oil yield of the oil press, extrude the oil in the material, and flow out of the garden discharge gap and strip gap.
