Rice bran oil extraction process introduction:

1. Separating screen

To separate rice bran and remove the stone, straw and other inpurities inside rice bran and increase oil yield.

2. Conditioner

To change rice bran physical properties,easier for granulation or expansion.

3. Expanding or granulating machine

To make rice bran into granule and increase penetrability good for oil extraction.

4. Rice bran oil extraction machine:

Can use rotocel extractor, loop type extractor for oil extraction according to production capacity.

5. Meal desolventizer

After extractor , using desolventizer to dry meal.

6.Muti-effective Evaporators

After solvent extractor ,the mixed oil need multi-effective evaporator to evaporate solvent in order to separate solvent and rice bran oil.

7.Solvent recovery

Evaporated solvent will be transformed into liquid solvent and be recovered and reused again.

8. Crude rice bran oil refinery process:

A: Hydrated degumming

For physical refining of rice bran oil ,degumming is basic step in rice bran oil refinery process. Degumming process can remove gum in crude rice bran oil.

B: Vacuum drying

To dry hydrated oil


To dewax before physical deacidification which helps deacidification.

D: Decoloration

To remove colorant from oil.

E: Deacidification and deodorization

Using physical deacidification tower to remove free fatty acid and odor.


Rice bran oil contains wax and fat which need to be removed.
