This project includes 50TPD rice bran pre-treatment line, 50TPD solvent extraction line, 10TPD rice bran oil refining line and 10TPD rice bran oil dewaxing line.
Rice bran oil manufacturing process
1. Separating screen
To separate small rice rags in order to reduce starch inside rice bran and increase oil yield.
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. Oil extraction
Can use rotocel extractor, loop type extractor for oil extraction according to production capacity.
5. Meal desolventizer
After extractor , using desolventizer to dry meal.
After solvent extractor ,the mixed oil need multi-effective evaporator to evaporate solvent in order to separate solvent and rice bran oil.
Evaporated solvent will be transformed into liquid solvent and be recovered and reused again.
8.Crude rice bran oil refining
♦ Hydrated degumming
For physical refining , degumming should be complete. Acid value of rice bran is very high , so it’s better adopt physical refining. Degumming is basic step for good physical refining ,thus gum should be removed completely.
♦ Vacuum drying
To dry hydrated oil
To dewax before physical deacidification which helps deacidification.
To remove colorant from oil.
♦ 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.
