Rice Bran Oil Production Line

Complete rice bran oil processing plant includes rice bran oil granulation or expansion, rice bran oil extraction and rice bran oil refinery. A professional manufacturer for rice bran oil processing plant , we provides turnkey project including design rice bran oil processing plant , manufacturing machines for complete rice bran oil production line , installing and commissioning rice bran oil processing plant until start-up. Here we will introduce you advanced technology of rice bran oil manufacturing process.

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.

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. 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.

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 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

♦ Dewaxing

  To dewax before physical deacidification which helps deacidification.

♦ Decoloration

  To remove colorant from oil.

♦ Deacidification and deodorization

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

♦ Defatting

Rice bran oil contains wax and fat which need to be removed.
Pre-pressing Process of Rice Bran Oil Extraction Line

For larger capacities, the oil mill is used for pre-pressing where the initial oil is extracted mechanically. Then pre-pressed cake is sent to the solvent extraction plant. Pre-pressing is a traditional method to process high oil-content oilseeds. The advantages of pre-pressing technology are as follows:
1. Versatile in processing many oilseeds, such as rapeseed, cottonseed, sunflower seed and safflower seed, peanuts and sesame seeds.
2. According to customers’ request, the complete explosion-puffing process is available which saves energy and obtains high quality oil.
3. Multi-stage filtration to the pre-pressed oil.
4. Less stringent requirements as to oilseed quality.

Rice bran oil manufacturing process is one of most difficult process among vegetable oil processing because of high acid value of rice bran , you can contact us directly for more details We will design rice bran oil processing plant as your requirement, choose for you best combination of rice bran oil production line.
