Oil press knowledge and working principle
The oil press of Henan VIC Machine is a kind of oil processing machine, and is a machine for extracting vegetable oil by pressing the pretreated oil blank. The screw press used as a pre-presser pre-presses the oil at a relatively high pressure, and then puts the pre-pressed cake into an oil press to continue pressing or extracting oil by leaching. Therefore, the volume of the pressing and pressing at the inlet and outlet ends is large, and the production capacity is also large. The oil press can work continuously, the labor intensity is small, and the slag cake after oiling is thin and small, which is convenient for comprehensive utilization.
Working principle:
When the oil press is running, the processed embryo enters the pressing chamber from the hopper. Pushing in from the spiral of the squeeze chamber and pressing. Because the embryo is carried out in the pressing chamber of the oil press, under the condition of high pressure of the pressing chamber, a large frictional resistance is generated between the embryo and the pressing screw and the pressing chamber. This will cause friction between the micro-materials and cause relative motion. On the other hand, the root diameter of the snail is gradually thickened. When the screw is rotated, the thread can push the embryo forward and flip it outward, and the layer near the surface of the screw thread rotates along with the shaft, so that each of the embryo particles in the chamber is Instead of waiting for speed, moving in the same direction, there is also relative motion between the particles. The heat generated by the friction satisfies the heat required for the operation of the oil pressing process, helps to promote the thermal denaturation of the protein in the embryo, destroys the colloid, increases the plasticity, and also reduces the viscosity of the oil, which is easy to precipitate oil. Therefore, the oil yield of the oil press is improved.
