Screw press

Screw press is mainly used for processing of individual home press. The product is a fully automatic hydraulic press, the production of small, but simple and convenient. Now the main products are screw press. Cold-pressed also has screw press, the price is relatively low, but the oil rate is not high. Is flourishing is automatic screw press, which is ten years ago in South Korea to introduce domestic technology, using vacuum filtration, automatic temperature control function. Well out of the product oil quality. Fragrant taste, the oil rate is still high. Now mainly used in rural areas to do the processing. Or do live processing in urban areas, so it looks to produce more transparent and give customers more confidence. Carry on the business of a great advantage. Many areas are now operating according to this model, profits are quite lucrative.

Almost all oil crops can be squeezed through the screw press. Including peanut, soybean, sunflower, rapeseed, walnut, cottonseed, and so on. Especially peanut oil and sesame oil, this because the price is more expensive. Often false and oil extraction on the market, bad for your health, so the comparison site processing business methods to meet the needs of users of genuine importance. Now the way is mainly used in urban areas.
When the press operation, treated good extra virgin oil from the hopper into the breech. By pressing the spiral turn make the material to keep the embryos in advance, be pressed. Since the material in the press is pressing embryo bore is carried out at the state of motion, pressing bore under high pressure conditions, resulting in a great deal of friction between the material and the pressing screw embryos, embryos and virgin material breech, so friction can cause relative movement between the micro-material parison. On the other hand, due to the pressing screw root diameter is gradually thickening Park pitch is gradually reduced, so that when the pressing screw rotates, the threaded hard material embryos that can move forward, but also outward and upward while pressing screw thread close as the surface of the material layer is also pressed shaft. This bore in the virgin material of each embryo particle velocity is not the same direction, but also exist between the relative movement of the particles. The heat generated by the friction and the oil extraction process operation to meet the necessary amount of heat to help promote the parison thermal denaturation of proteins, destruction of the gel, to increase the ductility, while also reducing some of the oil to the viscosity tends to be precipitated, and thus improved oil yield screw press, so that there is an oil feed squeeze out and drain discharge gap and the gap flow from the garden bar.
