Rice bran oil equipment

Rice bran oil equipment manufacturers pointed out that the more commonly used method is the silica gel decolorization method, rice bran oil obtained by solvent extraction, its color is dark brown, dark green brown or green yellow, which mainly depends on the degree of deterioration in the storage of rice bran, oil production method and processing conditions. In general, the dark color of rice bran oil can not be completely removed, so it is difficult to produce clear and light color rice bran oil. The decolorization of rice bran oil was studied by silica gel. The decolorization of rice bran oil was studied by silica gel column filtration and by silica gel mixed with mixed oil. The disadvantage is that the velocity of mixed oil is slow when it passes through the silica column (especially when it is extracted by solvent). Silica gel decolorization can be improved into silica gel column - filtration treatment - degumming - dewaxing - refining - decolorization and deodorization.
