Processing process of rice bran oil

Abstract

The invention discloses a processing process of rice bran oil. The processing process comprises the following steps of sequentially feeding rice bran to a feeding auger, a 1# lifter and a bran and tip separating sieve, and then entering into a 2# lifter; then, entering the rice bran processed by the above steps into a softening pot for being softened, passing through an expanding machine by a 3# lifter, conveying to a drying box for being dried by a belt conveyor, entering into a horizontal scrapper by a 1# buried scraper lifter and then entering into a material storage box, and then feeding to a rotocel extractor by a 2# buried scraper lifter; and finally, passing the rice bran through a desolvation dryer by a 3# buried scraper lifter, entering into a rice dreg outlet horizontal scraper by a 4# buried scraper lifter and then entering into the material storage box, wherein the material enters the rotocel extractor which is further connected with a mixed oil filter tank, a mixed oil temporary storage tank and a salting-out tank, and the rice bran is finally processed into crude bran oil by a 1# evaporator, a 2# evaporator, and a laminated stripping tower. The processing process disclosed by the invention overcomes defects in the prior art, is low in production process energy consumption and high in oil extraction rate; moreover, the processing method of the rice bran oil is good in discoloring effect.

Description

technical field [0001] The invention relates to the technical field of food production, in particular to a processing technology of rice bran oil. Background technique [0002] Rice bran is a by-product of rice processing, with an oil content of 15-22%, and rice bran oil is a high-quality edible oil containing glycolipids, glycoproteins, fatty acids and other lipids, which can promote human growth; , Anti-thermal oxidation and other advantages, known as "healthy oil", "nutritious oil", has a very good market prospect. There are three main production processes for rice bran oil, one is mechanical pressing, the other is solvent leaching, and the third is supercritical extraction. Among them, the oil yield of solvent leaching is higher than the other two, and it is easy to produce on a large scale, so , strong applicability. However, in the prior art, the rice bran oil produced by the solvent extraction method has the characteristics of darker color, and the production proces...
