Corn germ oil is also called as corn oil, which not only is a healthy oil, but also has obvious curative effect and preventive effect on heart disease, thrombophlebitis, reproductive dysfunction, muscular dystrophy and nutritional encephalomalacia.

Besides, in terms of nutrition, the fat content of corn germ is between 17% and 45%, accounting for about 80% of the total fat content of corn. The biggest feature of fatty acid in corn oil is that its unsaturated fatty acids content is up to 80% ~ 85%.

Many consumers don't know what is corn germ. You can see the picture below.

The structure of corn

As the picture shows, the small part of each corn kernel is corn germ. Only the corn germ contains oil, and other part is corn starch. If you want to produce corn germ oil, you must have raw material-corn germ, not corn. Because 100 tons corn just get 8 tons corn germ. So generally, corn germ, as a byproduct, can be got from corn starch processing plant.

DOING - Henan Glory Corn Germ Oil Processing Machine

To buy corn germ oil processing machine, you had better choose suitable based on yourself requirement. DOING - Henan Glory can provide different kinds of corn germ oil processing machine, which can be customized with different process, different capacities, etc.

The oil content of corn germ is 30%-48%. It can use pressing method, or solvent extraction method to produce oil. According to the processing capacity, we can provide you three scale corn germ oil processing machine.

1. Small Scale Corn Germ Oil Processing Machine

Below 10 tons corn germ per day, you can choose small scale corn germ oil processing machine, which includes roaster, oil presser, filter and conveyor.

Two kinds of small scale corn germ oil processing machine

Roaster is used to fry the corn germ, which can increase the oil yield and improve the flavor of the corn germ oil.

Oil presser uses physical squeezing principle to extract oil out of corn germ.

Filter can remove the impurities from crude corn germ oil, and improve the quality of corn germ oil.

Conveyor is used to transport the corn germ in the whole corn germ oil processing process.

2. Medium Scale Corn Germ Oil Processing Machine

10-30 tons per day, you can use pressing method to extract corn germ oil. Because of the larger processing capacity, so the corn germ need pretreatment, which can remove the impurities in corn germ and process the corn germ into best condition for pressing, in order to improve the oil yield.

Medium scale corn germ oil processing machine

After pretreatment, the processed corn germ will be sent into oil presser, and the pressed corn germ oil will be sent into filter to remove the impurities. In the end, you can get pure pressed corn germ oil and corn germ pressed cakes.

3. Large Scale Corn Germ Oil Processing Machine

More than 30 tons per day, you can choose two methods to extract corn germ oil. The machines needed contain corn germ oil pretreatment machine, oil presser machine, oil solvent extraction machine and crude oil refinery machine.

Large scale corn germ oil processing machine

Corn germ oil pretreatment machine and oil presser machine is in corn germ oil pretreatment and pressing workshop. Their aim is to process corn germ and press it to get part of oil. Then the corn germ pressed cakes will be sent into corn germ oil solvent extraction workshop. Here, more oil will be extracted from the corn germ pressed cakes and the oil residual rate will be less than 1%. The crude oil refinery workshop is to refine crude corn germ oil and remove impurities from oil. After refining, the corn germ oil will be reach grade 1 level, which can be sold in the supermarket.

Why does Corn Germ Oil Need Refining?

First reason is that oil got from solvent extraction plant must be refined, so as to reach the national standards.

The second reason is that corn oil contains free fatty acid, phospholipid-bound protein, mucous and other non-glycerol vinegar impurities, which exist in corn oil in the form of colloid. Besides, there are also wax content in the corn germ oil. These substances will affect the flavor and quality of corn oil.

So crude corn germ oil need five steps refining processes: De-gumming, de-acidification, de-colorization, de-odorization and de-waxing.
