The working principle of screw oil press

oil press machine is composed of strips and round rows, its advantages are high pressure, high oil yield and thin cake. It is wear-resistant, the pressed material is relatively clean, the efficiency is high, and the process is simple and easy to operate. Our machine separates the oil from the raw material by means of purely physical screw extrusion. screw oil press machine can press any oily material whose moisture content is less than 10%, such as coconut, peanuts, soybeans, sunflower, rapeseed, walnut, cottonseed, palm kernel, palm fruit, etc. The spare parts are in stock and there is a detailed list of spare parts to ensure the after-sales service without delaying the customer's production time.

The pressing method has a long history, and its technological process is relatively simple. From the pretreatment of the raw materials to be pressed, there are cold pressing and hot pressing methods, which are also called cooked pressing methods. Cold pressing means that the raw materials are directly put into the oil press to squeeze out the oil without being roasted or steamed. This method is relatively lighter in color and brighter in color, but the oil yield is low, and the oil tastes not strong and mellow. . The hot press must dry the oil crops before squeezing. The purpose is to reduce the moisture of the raw materials, increase the activity and fluidity of the oil molecules, thereby increasing the oil yield and ensuring the fragrance of the oil. But it also destroys the chemical composition of the oil, resulting in a darker and darker color of the oil.
