Our company can supply you with the best corn oil extraction machine,the corn germ pretreatment and oil pressing machine uses latest technology and corrison-resistant materials, you can get high quality corn germ oil with low energy consumption and high efficiency by using our corn germ pretreatment and oil pressing machine. The following is corn oil production process

Corn germ pre-pressing process

Generally use screw oil press. To ensure higher oil yield, in addition to meet the above conditions, the pressure of corn oil press shall be above 69 MPa. After pressing, residual oil in the cake is controlled at 6% to 7%, and the moisture content of the cake is 3% ~ 4%. For safety reasons, the moisture content of the cake shall be adjusted to 12%.

Corn oil solvent extraction

The moisture content of the corn germ must be controlled in a proper range to meet later pre-pressing and solvent extraction process moisture requirements. At the same time, proper moisture content is also conducive to the corn germ flakes do not stick to the rolling stock, easy to make maize embryos pressed into uniform slices, and create favorable conditions to reduce residual oil in flakes. The suitable water content of the dried flakes is 10% ~ 11%. To prevent the powder of the flakes, the thickness should be controlled at 0.35 ~ 0.45mm. Steaming, pre-pressing and cooling can further change the internal and external structure of the germ particles, so that the protein can be frozen and modified to reduce the resistance of the oil molecules spread outward, at the same time adjust the moisture and temperature of the material. For the corn germ in pre-pressing &solvent extraction technology, the water requirement of the material shall be controlled at 4% ~ 6%. For 6# solvent oil, the temperature of the feeding corn germ flakes is better controlled at 50 ~ 55℃. The operation of the corn germ solvent extraction, purification, evaporation and solvent recovery is conducted as normal solvent extraction process.

Aqueous enzymatic corn oil making

The aqueous enzymatic solvent extraction technology is a process that extracts oil from plants with a mixed liquid of water and enzyme. It’s a new type oil making technology.
