soybean oil production plant, soybean oil press,

The soybean oil is rich of linoleic acid, α-linolenic acid, fatty asic , Vitamin E, Vitamin A, Vitamin D and some others nutriment . In nowadays, the soybean oil is already the main important edible oil. Soybean is the main oil seeds of the world.

The soybeans are first cleaned, dried and dehulled to oil extraction. The soybeans are also heated to about 75°C to coagulate the soy proteins to make the oil extraction easier.

Extraction of soybean oil, first the soybeans are cut in flakes which are put in a percolation extractors and immerged with a solvent, normally hexane. Counterflow is used as extraction system. After removing the hexane, the extracted flakes only contain about 1% of soybean oil and is used as livestock meal or to produce food products such as soy protein. The hexane is separated from the soybean oil in evaporators. The evaporated hexane is recovered and returned to the extraction process.

Purification of soybean oil
The crude soybean oil still contains many oil-insoluble and oil-soluble impurities that needs to be removed. The oil-insoluble material are removed with filtration and the soluble materials is removed with different processes including degumming (removing of phosphatides), alkali refining (washing with alkaline solution to remove free fatty acids, colorants, insoluble matter and gums) and bleaching (with activated earth or activated carbon to remove color and other impurities.
