Stupid soybean oil press
The working principle of the soybean oil press is to use mechanical external force to increase the temperature, activate oil molecules, and squeeze the oil out of the oil. The specific process is as follows:
1. The processed oil enters the pressing chamber from the hopper, and the pressing screw rotates to continuously push the material embryo inward for squeezing.
2. Since the material embryo is in motion in the pressing chamber of the oil press, under the condition of high pressure in the pressing chamber, great frictional resistance is generated between the material embryo and the pressing snail, and between the material embryo and the pressing chamber. This will cause friction between the embryo particles and cause relative motion.
3. Since the diameter of the root of the snail gradually increases and the pitch gradually decreases, when the snail rotates, the thread force material embryo can be pushed forward and turned outward, and at the same time it is close to the thread surface of the snail. The material layer also rotates with the pressing shaft. In this way, each embryo particle in the pressing chamber does not move at the same speed and in the same direction, but there is relative motion between the particles.
4. The heat generated by friction meets the necessary heat for the operation of the oil extraction process, which helps to promote thermal denaturation of the protein in the embryo, destroys the colloid, increases the plasticity, and also reduces the viscosity of some oils that are easy to separate out. , thus increasing the oil yield of the oil press, causing the oil in the oil to be pressed out and flow out from the gaps in the garden rows and strips.
