3.Introduction of Degumming&Deacidification process of crude rice bran oil refinery plants:

Degumming:

The purpose of degumming is to remove the phospholipid, sugar, protein, trace mental, 

and some other impurities, which have bad effect on the stability of the oil. 

Deacidification:

Add some certain quantity of alkali to neutralize the free fatty acids. During this 

process, some soapstock will be produced.The soapstock will be separated from the 

oil after using the centrifugal machine.

3.Introduction of Decoloration process of crude rice bran oil refinery plants:

Mix the oil with activated clay in the oil soil mixing tank, and 1 ton oil needs 5kg 

clay. Then stir it 10 minutes at 10°C. Next, pump the mixed oil into the 

decolorization tower. It use steam to heat the mixed oil at 100°C, and the process 

lasts 30-40 minutes.
