Rice Bran Oil Extraction: You can extract the crude rice bran oil using a solvent in a chemical method or in a mechanical way with oil presses. After proper processing, the bran is fully stable enough for the extraction process where the oil is extracted, giving two products, a high-quality crude rice bran oil, and defatted rice bran.
What is rice bran?
Rice bran is a byproduct of the rice milling industry obtained from milling of brown rice to produce white rice. It contains 15%?20% of oil. Apart from oil, rice bran is a promising source for proteins, carbohydrates, dietary fiber, vitamins, tocopherol, γ-oryzanol, and phospholipids ( Tao, 1989; Houston, 1972; Saunders, 1986 ).
How is rice bran oil processed?
Rice Bran Oil Refining: Crude rice bran oil is again processed in a process called refining, which separates the majority of free fatty acids and prepares an oil that is appropriate for a variety of animal or agricultural uses.
What is the output rate of rice bran oil mill machinery?
The output rate of rice bran oil mill machinery is between 8-11% and the capacity is from 5t to 100t per day. In order to obtain high quality refined rice bran oil, the refining process begins by reducing excess free fatty acid and then decreasing the color with activated clay.
