Rice bran oil factory equipment is the main machine to produce rice bran oil. The full set of rice bran oil factory equipment mainly includes: rice bran oil pretreatment machine, rice bran oil extraction machine and rice bran oil refinery machine. The oil residue in cake after prepressing will be about 15%, oil residue in meal after solvent extraction plant will be less than 1%.Rice bran oil refinery machine is mainly to refine the crude oil comes from prepressing machine and solvent extraction machine, after refining, the oil can meet with first grade GB standard.
Introduction of complete set of rice bran oil pretreatment and prepressing machine:
Pretreatment and prepressing section is the basic parts for a rice bran oil mill plant. This section includes: cleaning, puffing process to adjust the peanut seed into the best condition for oil pressing, easy to press oil out and easy for next production section.
Process flow chart of rice bran oil pretreatment and pressing machine:
Raw material (rice bran) → Cleaning →Conditioning → Puffing(extrusion machine) → solvent extraction plant
Introduction of complete set rice bran oil solvent extraction machine:
Solvent extraction section is the second part of rice bran oil mill plant. This solvent extraction section includes: extraction system, D.T.D.C system, miscella stripping system, cooling and recycle system. After this process you can get most oil out from rice bran cake.

Introduction of complete set rice bran oil refinery machine:
After oil pressing process or oil solvent extraction process, we get crude rice bran oil. However, the crude rice bran oil can’t eat and sell to the market. The crude rice bran oil must be processed with rice bran oil refinery plant. Rice bran Oil Refinery Plant can remove unhealthy impurities such as phosphatides, free fatty acids (FFA), pigments, off-flavor, etc. After refining, the flavor, color and smell of rice bran oil is improved, the stability is improved which is good for long time storage, the smoke point of oil is increased.
What’s more, rice bran oil refinery can refine almost all types of oils, such as corn oil, soybean oil, peanut oil, cottonseed oil, rapeseed oil, sunflower oil, palm oil, palm kernel oil, and so on.
Refinery section is one of the most important process of Rice Bran Oil Mill Plant. This section mainly includes: Degumming, Deacidification, Decolorization and Dodorization etc. This process can remove the hazardous substances and useless dross, to get the GB standard oil.
Process flow chart of rice bran oil refinery machine:
Degumming and Deacidification Section: Rice bran oil degumming and deacidification section uses washing method to separate soap residual from mixing oil, providing preparation for next step rice bran oil refinery process.
Decolorizing Section: Rice bran oil decolorizing section is mainly used to remove oil pigment, residual soap and metal ions during rice bran oil milling process.
Deodorization Section: Rice bran oil deodorization section composes of part of crude rice bran oil mill processing equipment. It plays important part in improving oil quality after crude rice bran oil process.
Dewaxing Section: Because there is some wax in the sunflower oil, corn oil, rice bran oil, etc., if you want to get the first grade cooking oil , de-waxing machine is required. It depends on the customer.
After above steps, the final product is refined edible oil ,which can reach the level of consumption! Of course, we can produce and supply rice bran oil refinery plant with various kinds of capacity and oilseeds.
