Pretreatment process: rice bran → magnetic separation → bran and rice separation → softening and tempering → rice bran puffing → drying and cooling → sending to the extraction workshop → puffed rice bran → oil extraction → mixed oil treatment → crude oil

Exctraction equipment: exctraction system, wet meal steaming system, evaporation system and condensation system.

Process flow of rice bran oil refining:

Rice bran crude oil → phosphoric acid degumming → washing and drying → dewaxing → decolorization → physical deacidification and deodorization → degreasing → refined oil
