Rice Bran Pretreatment process: 

Rice Bran → Cleaning → Magnetic Separation → Separation of Rice Bran and Fine Broken Rice → Contioning → Expanding→ Drying→ Solvent extraction→ Crude Rice Bran Oil

Rice Bran Oil Solvent Exctraction: 

Solvent Extraction

Conditioned flakes are immersed in solvent (hexane) within a sealed extractor. Solvent dissolves oil from solids, producing miscella (oil+solvent) and solvent-wet meal.

Meal Desolventizing D.T.D.C

Wet meal enters DTDC where direct and indirect steam strip residual solvent. Steam vaporizes solvent while drying and cooling meal for safe storage.

Evaporation System

Miscella passes through evaporators where indirect heating vaporizes solvent. Rising film evaporators concentrate miscella, removing most solvent from crude oil.

Solvent Recovery

Solvent vapor from all stages is condensed, cooled, and recovered. Recovered solvent returns to extraction while non-condensable gases pass through mineral oil scrubber for final recovery.

Rice Bran Oil Refining:

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