Rice bran is the by-product of rice mill. Usually 100tons rice can produce around 6-7 tons rice bran. And the oil content rate of rice bran is a little low, around 13%-20%. But because of its rich nutrient substance, rice bran oil is very popular among consumers. Many investors are interested in rice bran oil production business. Here, Doing Company would explain how to extract oil from rice bran by modern methods?
Rice bran oil
Since the oil content rate of rice bran is not too high, so usually we don't suggest customers to start small scale rice bran oil processing plant like 1-20 tons per day, because if adopting pressing method, the residual oil rate is about 6-7%, which will lead to waste a lot. As for input capacity above 20 tons per day, you can adopt pretreatment then solvent extraction method, which includes cleaning, puffing, cooking and drying processes, then using N-hexane to extract oil from rice bran. And the most important is that the final oil residue is lower than 1%.
