Screw oil press

Almost all oil crops can be pressed by the fully automatic screw press. Including peanuts, soybeans, oil sunflower, rapeseed, sesame, walnut, cottonseed and so on. Especially peanut oil and sesame sesame oil, because the price is more expensive. There are often counterfeit and leaching oils in the market, which are bad for health. Therefore, the on-site processing method meets the needs of users who value genuine products at a reasonable price. It is now the main way of use in urban areas.

Fully automatic screw oil press, which is a domestic technology introduced in Korea more than ten years ago, with vacuum filtration and automatic temperature control functions. The product oil is of good quality. The taste is fragrant and the oil yield is still high. Now it is mainly used for processing in rural areas. Or it is used for on-site processing in urban areas, so that it seems that the production is more transparent and makes customers more assured. It is of great benefit to the development of business. Many regions now operate according to this model, and the profits are quite substantial.

The oil press is a new generation of high-efficiency and energy-saving oil press equipment introduced from South Korea and developed with the grain, oil and Food Research Institute of China Academy of agricultural mechanization. It meets the technical conditions and standard requirements of agricultural screw oil press of the Ministry of agriculture. The processed oil is original and pure, which is the best choice to create a "modern oil mill".

The oil press equipment is mainly composed of electrical control, automatic heating, adjustment, transmission, and vacuum oil filtering. The pressing screw is made of alloy steel by carburizing treatment to enhance the surface hardness and wear resistance; the pressing row is ground by a surface grinder to ensure the accuracy of the oil line and increase the oil yield; the standard components such as power distribution, vacuum and automatic heating are selected from well-known domestic Brand, optimize the machine configuration; the surface of the machine is treated with stainless steel and chromium plating, which meets food hygiene standards.

Working principle of screw oil press:

When the oil press is running, the processed oil enters the press chamber from the hopper. The raw material is continuously pushed inward by the squeezing screw for squeezing. Because the material embryo is in motion in the press chamber of the oil press, under the condition of high pressure in the press chamber, a great frictional resistance is generated between the material embryo and the snail, and the material embryo and the press chamber. It can cause friction between the micro-materials of the embryonic material and cause relative movement.

On the other hand, because the diameter of the root circle of the snail is gradually increased and the pitch is gradually reduced, when the snail is rotated, the thread-strengthened blank can be pushed forward and turned outward, and it is close to the screw thread at the same time. The surface material layer also rotates with the press shaft. In this way, each embryo particle in the press chamber does not move at the same speed and in the same direction, but there is also relative movement between the embryo particle.

The heat generated by friction meets the heat necessary for the operation of the oil extraction process, which helps to promote the thermal denaturation of the protein in the raw material, destroys the colloid, increases the plasticity, and reduces the viscosity of some oils, which is easy to precipitate. The oil output rate of the oil press is increased, so that the oil in the material is squeezed out and flows out from the gaps in the circular row and the gap in the row.
