The production process of corn germ oil involves several steps:
Corn Germ Extraction: This is one of the important steps for oil extraction. Based on the different crushing resistance of corn embryo and endosperm, the endosperm is first crushed with rolling equipment and then the corn embryo is screened out with screening equipment.
Impurity Removal: The corn germs are thoroughly cleaned before pressing by removing impurities like slag and powder in the germ. They are purified with a vibrating screen to improve the purity of the germ.
Drying: The water content of the newly extracted corn germ is high. To prepare it for pressing, it is needed to reduce the water content to less than 9%.
Pressing: The corn germ is gently warmed to the press temperature and then fed into a screw press. The resulting products, corn oil and corn press cakes, are then immediately further processed.
Oil Extraction: A combination of mechanical and solvent processes extracts the oil from the germ. The oil is then refined and filtered into finished corn oil.
It's worth noting that the corn germ production usually occurs during the production of starch. Also, the quality of corn germ only accounts for 10% – 15% of the grain, but the crude fat content of corn germ is particularly high, accounting for 33% – 56% of the weight of the whole germ. Corn germ oil is rich in vitamin E and unsaturated fatty acids, such as linoleic acid and oleic acid, which have a protective effect on cardiovascular and cerebrovascular.
The investment cost of the corn germ oil extraction production line is high, and the quality of the corn germ oil equipment and the production site requirements are extremely important. Therefore, the strength, technology and experience of the equipment manufacturer are very important. The Henan Huatai Cereals and Oils Machinery Co., Ltd. covers an area of 170 acres and has its own R&D and design team. It is familiar with the characteristics of various types of oils and provides equipment for edible oil plants according to demand.
