soybean oil processing machine

Soya bean oil is a kind of frequently-using cooking oil which is commonly sais soybean salad oil. Soybean oil is extracted from the seeds of the soybean seeds through cold pressing or hot pressing. about cold pressing oil, it has light color and light soybean flavor.
Soya bean oil iprocess begins with the cleaning of soybeans to remove impurities. The beans are then heated to adjust for moisture content and to loosen the hull for improved dehulling. They are then cracked by passing through rollermills and the hulls are removed.

The dehulled/cracked soybeans are heated to high temperature to soften and condition them, after which they are rolled into flakes. The flakes are then subjected to an extraction process in which hexane, a petroleum distillate solvent, is used to remove soybean oil from the flakes. From this process, miscella (the mixture of hexane and oil) and wet meal are obtained.

After the Soya bean oil i is removed, the wet meal goes through a desolventiser-toaster to remove hexane and inactivate enzyme inhibitors to improve nutritional value and digestibility of the meal. The flakes are then dried, cooled and ground to produce soybean meal. The level of protein and fibre is then adjusted by adding soybean hulls.

Removal of part of the carbohydrates (sugars) from defatted flakes will produce soy protein concentrate. Soy protein concentrate is about 70% soy protein and is basically soybean without the water soluble carbohydrates.
