Corn oil processing is one of the most popular seed processing in the entire oil mill plants. Seed processing plant including corn oil plant,peanut oil plant, sunflower oil plant etc.
Corn oil and corn meal are both obtained from corn. With the help of right oil extraction machinery, corn can be extracted into useful products such as corn oil and corn meals.
Corn oil processing
The corn oil processing generally includes the steps of cracking corn grain having a total oil content of from about 3% by weight to about 30% by weight and extracting a corn oil from the cracked corn grain.
The corn oil is useful for making nutritionally enhanced edible oil or cooking oil, lubricants,biodiesel, fuel, cosmetics and oil-based or oil-containing chemical products. The extracted corn meal is useful for making enhanced animal feed rations, snack food, blended food products, cosmetics, and fermentation broth additive.
Corn Oil Plant
Corn oil plant is one of the most popular Oil plants all over the world. with certain procetures, qualified corn oil can be obtained.
Corn oil processing
Crude corn oil is filtered and then degummed. In steam degumming, steam is introduced at a volume of not more than 3 percent of the oil and is absorbed by lecithin or other gums, making them heavy enough to be removed by centrifugation.
In alkali degumming, a heated sodium hydroxide solution is used to absorb the gums and also neutralize any free fatty acids, followed by “washing” the oil with hot water to remove any soap formed in the process. By-products of the alkali process are sold as soap stock.
Corn oil is “bleached” with clay that has been “activated” with acid wash to remove any metals native to the clay. As a result, the clay absorbs color pigments, residual soap products and metal ions from the corn oil.
The clay is then removed from the oil by filtration. If a partially hydrogenated product, such as margarine or shortening, is being produced at this point in the process, the heated oil is exposed to hydrogen gas under pressure.
The oil is refrigerated to crystallize any waxes, which are then removed by filtration. A continuous stream steam treatment deodorizes the oil in a distillation tower, carrying any remaining impurities out the top of the tower with the rising steam as the finished oil is removed from the bottom.
Corn Oil Production
Corn oil is a commonly used oil that is commonly used across the world for their cooking needs. As a result, corn oil production is becoming more and more popular around the world.
With years’ experience in the corn oil production field, we gained a lot of experience. If you are interested in corn oil production or any other oil seed production, this is the right place to sart.
Corn oil production process is a complicated process, the entire production process also needs a series of corn oil processing equipment. Corn oil production starts with corn seed pretreatment, almost all corn oil is expeller pressed, then solvent extracted using hexane or isohexane.
The solvent is evaporated from the corn oil, recovered, and re-used. After extraction, the corn oil is then refined by degumming or alkali treatment, both of which remove phosphatides. Alkali treatment also neutralizes free fatty acids and removes color (bleaching). Final steps in refining include winterization (the removal of waxes), and deodorization by steam distillation of the oil at 232 – 260C (450 – 500F) under a high vacuum.
Some specialty oil producers manufacture unrefined, 100% expeller pressed corn oil. This is a more expensive product since it has a much lower yield than the combination expeller and solvent process, as well as smaller market share.
