The invention relates to a refining method of rice bran oil, which adopts crude rice bran oil as raw oil. The rice bran oil is obtained through the procedures such as degumming, oil-foot separation, dewaxing, decoloration, high-temperature deacidification and deodorization, freezing and degreasing. The weaknesses of the traditional refining method that during the degumming, the neutral oil loss is large, partial neutral oil is neutralized by NaOH during the deacidification process and free-fatty acid process yield of the oil grease is reduced are overcame. A combination-type deacidification is adopted during the high-temperature deacidification process, and the acid value can be reduced to 3 through one-time physical deacidification. The utilization rate of the raw material and the product yield are improved, and the environmental pollution caused by the chemical refining can be greatly reduced. The deacidification process is free from the chemical reaction, so the loss of the oil grease is reduced, and the refining rate of the oil grease is improved. The consumption of the auxiliary raw materials and the labor can be reduced, and the price of the distilled fatty acid is better than that of the acidification oil; therefore, not only the production cost is reduced, but also the economic benefit is improved.

The invention relates to a process for extracting high-grade rice bran oil by a physical method, which utilizes the partial pressure of water vapor to reduce the partial pressure of free fatty acids in the oil and also reduce the boiling point temperature of the free fatty acids under high vacuum conditions, so that the free fatty acids can also be gasified at a lower temperature (240 DEG C) lower and further be separated from the oil. The chemical refining aims to further reduce the acid value, and ensure the oil color; while the process adopts the three-time bleaching and deodorization combining method to achieve the purpose. The three-time bleaching is that a mixing bleaching agent is used to remove 'blue' and other pigments produced in the deacidification process, and the deodorization is that the water vapor distillation principle is utilized to further remove the free fatty acids in the oil, so that the acid value and the like meet the requirements of product quality standards. Compared with the existing refining process, the process has high yield increasing by about 2-3% under the same conditions, and large micronutrient retention capacity, greatly retains nutrients, and significantly reduces the discharge amount of sewage.
