Corn oil press is suitable for small and medium-sized oil processing plants and individual professional households. It can also be used in the pre pressing process of oil mills or as a small oil pressing equipment for household use. The corn oil extracted by corn oil press has rich nutritional value and broad application prospects. A household oil press is a healthy, economical, and practical kitchen appliance that allows users to easily produce fresh, additive free cooking oil at home. When selecting and using, attention should be paid to safety, maintenance, and the selection and storage methods of fuel.

The working principle of a corn oil press mainly involves the physical pressing process. After the processed corn enters the press chamber of the oil press, the rotation of the press screw continuously pushes the corn embryo inward for pressing. Under high pressure conditions in the squeezing chamber, significant frictional resistance is generated between the embryo and the squeezing screw, as well as between the embryo and the squeezing chamber, resulting in friction and relative motion between the embryo particles. The heat generated by this friction helps to promote the thermal denaturation of proteins in the embryo, destroy colloids, increase plasticity, reduce viscosity, and thus make it easier to precipitate oil. At the same time, due to the special design of the snail press (the root diameter gradually increases and the pitch gradually decreases), the corn embryo can be flipped outward while advancing forward, improving the efficiency of oil pressing.
