Screw Oil ExtractorIntroduction:

HelicalOil Press MachineComprehensive specifications and reasonable pricing, suitable for consumers of various levels. SpiralOil Press EquipmentPrimarily used for individual household oil pressing. The spiral oil press features a dual cold and hot system, offering a variety of pressing functions. It's meticulously crafted, comes in multiple types, boasts high oil yield, and offers a wide selection.

Almost all oil crops can be pressed using a screw oil press, including peanuts, soybeans, sunflower seeds, rapeseed, sesame, walnuts, cotton seeds, and more. Particularly peanut oil and sesame oil, which are more expensive. There's often counterfeiting and solvent-extracted oil in the market, which is harmful to health. Therefore, the on-site processing method is more in line with the needs of customers who value authenticity. It's the primary method of use in urban areas now.

Screw oil press machine, a technology imported from South Korea over a decade ago domestically, featuring vacuum filtration and automatic temperature control. The oil produced has high quality, a pleasant aroma, and high extraction rate. It is primarily used for processing in rural areas. Alternatively, it's used for on-site processing in urban areas, which enhances production transparency and instills greater confidence in customers. This is highly beneficial for business development. Many regions are now operating on this model, yielding substantial profits.

Oil Press Machine, a product developed through the integration of South Korean technology with the China Academy of Agricultural Mechanization's Oil and Food Research Institute, meets the technical conditions and standards of the Ministry of Agriculture's spiral oil press machines. The oil processed is pure and retains its original flavor, making it the ideal choice for establishing a "modern oil mill."

The oil press equipment is primarily composed of electrical control, automatic heating, adjustment, transmission, and vacuum oil filtering components. The squeezing screw is made of alloy steel with carburization treatment to enhance surface hardness and wear resistance; the squeezing plate is ground on a flat grinding machine to ensure oil line accuracy and increase oil yield; standard components such as power distribution, vacuum, and automatic heating are selected from renowned domestic brands to optimize the machine configuration; the machine surface is made of stainless steel and chrome-plated to meet food hygiene standards.

Spiral oil press working principle:

As the screw oil press operates, processed oil material enters the press chamber from the hopper. The rotating press screw continuously pushes the material inward for pressing. Due to the movement of the material inside the press chamber under high pressure, significant frictional resistance is generated between the material and the screw, as well as between the material and the chamber walls, causing relative motion between the particles. Additionally, as the root diameter of the screw gradually thickens and the pitch decreases, the screw's rotation not only pushes the material forward but also flips it outward, while the material layers near the screw threads rotate with the shaft. This results in each particle within the material moving at different speeds and directions, creating relative motion between particles. The heat generated by friction also meets the heat requirements of the oil pressing process, promoting protein denaturation in the material, destroying colloids, enhancing plasticity, and reducing viscosity, which facilitates easier oil extraction. Consequently, the oil press's yield is increased, allowing oil to be squeezed out of the material and flow out through the circular and strip gaps.
