Corn germ is the raw material for the production of corn oil, which accounts for about 10% of the grain weight and has an oil content of about 35-50%. If you need to produce corn oil, you need to separate the corn germ from the corn first. Corn oil contains many saturated fatty acids. It is also rich in protein, amino acids, and vitamin E (tocopherol). Therefore, corn oil is used more frequently, and many edible oil manufacturers start to produce corn oil.

Corn oil production is divided into large, medium and small according to the output. Small-scale corn oil production is generally 1-10 tons/day. Zhongxing's engineers suggested using a steamer and oil press to produce corn oil. Such equipment is economical and cost-effective, and the quality of the corn oil obtained is also good, which is very suitable for small-scale corn oil production. If the corn oil output is more than 10 tons/day, then the corn oil production line is your good choice. It can greatly reduce your oil loss. At the same time, the quality of corn oil also meets the national standards and can be sold on the market.

The corn oil production line includes corn germ pretreatment and pre-pressing, corn oil extraction and corn oil refining.

1. Corn germ pretreatment and pre-pressing

The pretreatment of corn germ is an important step in corn oil production. The pretreatment of corn germ usually includes cleaning, softening, rolling and steaming. The purpose of pretreatment is to remove impurities in corn germ and change the structural characteristics of corn germ, thereby speeding up the efficiency of oil production and improving the quality of oil and by-products.

The pre-treated corn germ will produce crude oil and cake after being processed by the pre-press. Crude oil can be sold directly to refineries or transported to refineries for further processing, while cakes can be transported to the leaching workshop to obtain crude oil.

2. Corn oil leaching

Corn oil extraction usually includes four systems: corn oil extraction system, wet meal desolventization system, mixed oil treatment system and solvent recovery system. Corn oil leaching is mainly to obtain corn oil from the cake. After leaching, the residual oil content in the meal is less than 1%, thereby reducing oil loss.

3. Corn oil refining

The process of refining corn oil includes degumming, deacidification, decolorization and deodorization. The purpose of refining is to remove harmful impurities in crude oil that affect consumption, storage and industrial production, and to retain useful substances. After refining, you can get corn oil that meets national standards. Refined corn oil is good for human health, promotes absorption by the human body, and meets consumer demand.

The above is a brief introduction of the corn oil production line. As long as you tell us the raw materials and needs, our engineers can design a production plan for you to obtain high-quality corn oil. Looking forward to your call.
