Why should refining the soybean oil?

Soybean oil refining is very important process in the soybean oil extraction plant, it refers to remove the harmful impurity from the crude soybean oil,such as FFA( Free Fatty Acid), but not only the FFA, it also removes the unwanted impurities, color and odor which may have a negative impact on the taste, odor, and appearance of the oil. The soybean oil after soybean oil refining process is thinner without FFA, colorless and odorless, and also, it is good for human health and easy to storage.

Soybean oil refining process flow chart:

Crude soybean oil--degumming--deacidification(Alkali refining)--decoloration--deodorization--refined soybean oil

Brief introduction of soybean oil refining machine :

A. Refining pot: also named Dephosphorization and deacidification tank, under 60-70℃, it occurs acid-base neutralization reaction with sodium hydroxide. After stirring by reduction box,it can decrease the acid value in oil and separate the impurity, phospholipid which will enter into soap stock. The oil can be refined further.

B. Bleaching pot (decoloring pot): Also named bleaching and dewatering pot, it removes water from oil by vacuum. The bleaching earth is breathed into bleaching pot, after stirring,filtrated by filter and change the color of the oil.

C. Vertical blade filter machine: Equipped with vertical leaf filter to remove used bentonite from the oil, operating conveniently and continuously, low laboring tense, keeps environment well, keeps oil residence in deposable bleaching earth in low level.

D. Deodorization pot：It uses USU 304 stainless steel plate, under the vacuum condition of vacuum and high temperature (220-240℃), The deodorization system can remove fatty acid and other  rare delicacy high efficiently .make Meanwhile, the pot has the advantage of lowering steam consuming and avoid of the hydrolyzation of oil.

This soybean oil refining machines is applicable for refining of soybean oil, rapeseed oil, cottonseed oil, sunflower oil, peanut oil, rice bran oil, safflower oil, corn germ oil, camellia seed etc.
