For rice bran oil production, there must rely on rice bran oil processing machine. Generally, rice bran oil machine serves for rice bran pretreatment, rice bran oil pressing or extraction, rice bran oil refinery. To produce high qualilty rice bran oil, a series of rice bran oil production process should be involved.
How is rice bran extracted?
2.2. Oil Extraction and Solvent Screening First, 5 g of rice bran was put into a conical flask and then extracted using different solvents with a certain solid?liquid ratio at different temperatures in a water bath oscillator (THZ-83A, Jiangxing, Shanghai, China).
How is rice bran oil refined?
After the extraction, the crude rice bran oil is often refined in order to improve its quality and commercial value. The fundamental steps of the refining process include dewaxing, degumming, neutralization of the free fatty acids, bleaching, and steam deodorization.
How much oil can be extracted from rice bran?
Their results show that it is possible to obtain a maximum oil yield of 20.05 g/100 g rice bran in a three-hour extraction in ethanol with 6% of water at 82.5 °C, with a 4:1 w/w solvent-to-bran ratio and a stirring speed of 137.5 rpm. The – oryzanol content varies between 1527 and 4164 mg/kg of fresh rice bran.
