What is rice bran oil processing steps in plant?

Rice bran oil is a type of oil extracted from the outer layer of rice, which has many health benefits and a high smoke point. The processing steps of rice bran oil in a plant are as follows:


  1. Rice Bran Cleaning: The rice bran is screened to remove impurities and dust.
  2. Rice Bran and Broken Rice Separation: The rice bran is separated from broken rice and whole rice by a separator machine.
  3. Rice Bran Conditioning: The rice bran is heated and moistened to improve its oil extraction efficiency.
  4. Rice Bran Expanding: The rice bran is puffed or extruded by a machine to increase its surface area and porosity.
  5. Drying and Cooling: The expanded rice bran is dried and cooled to reduce its moisture content and prevent spoilage.
  6. Solvent Extraction: The dried rice bran is soaked in a solvent (usually hexane) to dissolve the oil, leaving behind a defatted rice bran meal.
  7. Refining: The crude rice bran oil is refined by degumming, water washing, vacuum drying, bleaching, de-waxing, and deodorizing to remove impurities, color, wax, and odor.
  8. Storage: The refined rice bran oil is stored in tanks or bottles for further use or sale.
