Mini crude oil refinery, 3T corn oil small oil refinery mini crude oil refinery. Corn oil is vegetable oils obtained from corn embryos, mainly composed of unsaturated fatty acids. Linoleic acid is an essential fatty acid, is an integral part of the constitution of human cells in the human body can be combined with cholesterol, showing mobility and normal metabolism, prevention and treatment of atherosclerosis and other cardiovascular ailments. The steroids in corn oil have cholesterol-lowering effect, rich in vitamin E, antioxidant, can prevent dry eye, night blindness, dermatitis, bronchiectasis and other functions, and have some anti-cancer effect.

Because of the characteristics of corn oil, and also because of its high nutritional value, good taste, non-perishable, so welcome by the people. In the United States and Europe, corn oil is used as an advanced and widely consumed edible oil, enjoy the reputation of "healthy oil", "rest assured oil" and "longevity oil".

Corn oil is obtained by the process of phospholipid removing, deacidification, degumming, bleaching, deodorization and dewaxing. Corn oil is clear and transparent, fragrant, high smoking point, it is suitable for fast fried and fried foods.

Hydration

1, hydration principle: hydration is by adding water to heat phospholipids, proteins, mucus and other impurities in oil and separate. The phospholipids will be expanded after absorbing water, making volume increases, and, the relative density of the protein, mucus and other impurities that is combined with phospholipids increases and sink precipitated.

2, hydration equipment and  process operations: hydration equipment is mainly hydration tank  and Water  removal  tank. Both structures are similar, both with a cylindrical conical bottom of the tank. Upper part of water injection tube and oil injection tube, intermediate with a stirring blade. There is head shaking pipe inside tank, and the bottom has outlet to release impurities.

Bleaching:

It adopts the way of bleaching earth and activated carbon for corn oil bleaching, the bleaching effect is better than individual bleaching earth. After the second activated carbon bleaching, the residual smell fades of bleaching earth in bleaching process becomes less.  Besides, Use a combination of both, which can save money.

Deodorizing process:

Deodorization principle: The vacuum deodorizer is commonly used type now, it means making steam through the corn germ oil, then remove the low boiling point impurities of oil(such as aldehydes, ketones and free fatty acids, etc.) and solvent smell of leaching by vacuum pump. Since the extracted gas contains water vapor, so even after the gas-liquid separator, atmospheric condenser separates the water droplets, making air and non-condensable gas discharged, so as to achieve the purpose of removing the peculiar odor.

    Before deodorizing take hydration or alkali refining process, it is better to remove the gum and impurities in oil, a deodorizer to and create favorable conditions for the next step of deodorization process, conducive to remove residual solvent and other odor.
