A short review of green extraction technologies for rice bran oil
Rice is one of the most important crops throughout the world, as it contributes toward satisfying the food demand of much of the global population. It is well known that rice production generates a considerable number of by-products, among which rice bran deserves particular attention. This by-product is exceptionally rich in nutrients, since it contains a wide spectrum of macronutrients
Oil Extraction: Rice Bran Oil is first extracted from the bran and germ. Oil Refining: The oil is then refined. Separation: The refined oil is separated into a clear liquid and hard fraction. In a more detailed process, the stages include transportation of the raw rice bran to the factory, crude oil extraction, oil refining, and oil storage.
Rice Bran Oil Refining Machine
1) Firstly, to pump crude rice bran oil into oil refining tank with heat conduction oil, and the temperature will reach about 70°C-80°C in one hour, then add acid or alkali to separate rice bran oil according to the acid value. After one hour’s processing and 4-6 hours deposit, then to convey soap stock to storage tank;
In this technology, the cell tissue of rice bran is hydrolyzed with protease and then oil is released to achieve the purpose of oil extraction (Hanmoungjai et al. 2001 ). In a previous study, Chen ( 2014) used alkaline protease to extract oil from rice bran and determined the optimal process parameters.
Physical refining of rice bran oil in relation to degumming
Physical refining of rice bran oil (RBO) with acidity between 4.0 and 12.4% has been investigated in relation to degumming and dewaxing pretretments. It appears that physical refining after combined low-temperature (10°C) degumming-dewaxing produces good-quality RBO with respect to color, free fatty acid, oryzanol, and tocopherol content.
Taking rice bran wax, a by-product of rice bran oil processing, as raw material, the product with a purity of 96.4% and chromaticity of 16.8 was obtained through phosphoric acid hydration and degumming, ethyl acetate extraction and oil removal and two-step decolorization treatment, which provided a better raw material for the further use of
Rice Bran Oil Making Machine
Rice Bran Pre-pressing Machine: Pre-processing generally includes the processes of screening and heating, set for making the rice bran well prepared for oil extraction, just like extraction of other oilseeds. The purpose of heating is stabilize the rice bran materials. There are two methods of stabilization, chemicals or using heat.

Rice bran oil refinery plant
Rice bran oil refinery plant is an indispensable part in the process of making rice bran oil. The rice bran oil obtained after the rice bran is pressed or leached is called crude rice bran oil, which contains more substances harmful to human, and influence the time of storage and the quality of the product.
Extraction at 60°C for ten minutes with 3:1 solvent to bran ratio using hexane solvent yielded about 3.6% more oil, while extraction with isopropanol produces 6.4% more oil than at 40°C. The yield of liquid propane was created to yield about 22.4% of oil in kg of rice bran at 0.76 MPa and ambient temperature.
