The invention discloses a method for refining rice bran oil by using short distance distillation. The method is implemented by putting crude rice bran oil in a buffer pot directly, transferring into a primary film evaporator by a pump for dehydration and desaeration, performing primary dehydration and desaeration under conditions of temperature being 60-120 DEG C and pressure being negative 0.8MPa to negative 0.95MPa; pumping the dehydrated and desaerated rice bran oil into a secondary short distance evaporator for deacidification with temperature controlled at 100-200 DEG C and pressure at 100-0.1Pa to obtain oleic acid with high acid value and rice bran oil with low acid value. The invention avoids heavy pollution processes of alkali refining and neutralizing chemical process for obtaining soda soap and process discharging waste water of washing when processing rice bran oil, the procedure is simple, high value oleic acid and low acid value rice bran oil can be distilled and separated, and the separation process is a physical process, the rice bran oil has no loss and the yield is very high.

The invention discloses a processing method of high-oryzanol rice bran oil. The rice bran oil is prepared from the processes of impurity removal, cleaning, drying, milling, puffing treatment, leaching, hydration degumming, vacuum dehydration, freezing dewaxing, decolorization and deacidification; water vapor needed for rice bran expansion treatment is supply by vacuum dewatering, so that the water vapor can be recycled, the energy loss is reduced, and the active ingredient (oryzanol) in rice bran is somewhat protected; the cost is reduced, the loss of energy is reduced by using physical deacidification, the effect of deacidification is improved, microwave-assisted leaching is used, the extraction speed of the rice bran is accelerated, and the oil yield of the rice bran is improved, and the production efficiency is improved. According to the processing method of high-oryzanol rice bran oil, the color and pH of the rice bran oil can be effectively guaranteed, the energy loss is reduced, the cost is reduced, the oil yield of the rice bran is increased, the quality of the rice bran oil is improved, and the production efficiency is improved.

The invention discloses enriched rice capable of blackening hair and nourishing blood and a preparation method of the enriched rice. The enriched rice is prepared from the following raw materials: millets, sweet buckwheat, sweet potato starch, longan, pumpkin seeds, barley grass powder, linseed oil, rice bran oil, Zornia gibbosa, spina date seeds, chestnut shells, Codonopsis pilosula and the like. The enriched rice has the efficacies of tonifying essence and blood, nourishing blood and yin and blackening hair and nourishing blood after long-term use.
