Rice bran oil content is 16% to 22%, which contains 60% to 70% unsaturated fatty acid. Rice bran oil after oil refining plant processing contains high nutrient, which is able to provide healthy component for human body health. Rice bran oil can be eaten directly, added in foods or other fields, which is a very helpful and wide applicable edible oil.
Even though there is especially mature rice bran oil refining process technology, however, there are still lots of key points should be taken into consideration. During rice bran oil refining plant, there are very strict requirement of crude rice bran oil. For instance, the required moisture and volatile matter of crude rice bran oil should be no more than 0.25%. Impurity contained in crude oil is less than 0.2%, and crude oil acid value is no more than 7mgKOH/g.
In addition, rice bran oil also has very strict quality indictor. The transparency of rice bran oil should be clear and transparent. There is no strange smell after physical oil refining process. The continuous rice bran oil refinery can greatly shorten connection time between rice bran and solvent oil. In addition, the new type physical rice bran oil refining adopts new type continuous deacidification and deodorization craft, which ensures high efficiency processing of vegetable oil.
