Rice bran oil two-phase extraction deacidification refining method

Abstract

The invention discloses a rice bran oil two-phase extraction deacidification refining method which is applied to a rice bran oil two-phase extraction deacidification refining system. The refining system comprises a base, a first filter cloth bag is arranged in a filter box, a circulating pump is mounted at the top of the base on one side of the filter box, and a material collecting tank is arranged in the base; and a mounting plate is mounted at the top of the base on the other side of the filter box through a supporting rod, a hydraulic cylinder is mounted at the top of the mounting plate, afixing plate is mounted at the output end of the hydraulic cylinder, a barrel body is mounted at the top of the base under the mounting plate through a discharging cavity, and a filter screen plate isarranged in the discharging cavity. According to the rice bran oil two-phase extraction deacidification refining method, by arranging the circulating filtration function and the squeezing function, the rice bran crude oil filtration effect is effectively improved, degumming and deacidification of subsequent procedures are facilitated, and meanwhile, the utilization rate of resources is increased,and resource losses are reduced.

Description

technical field [0001] The invention relates to the technical field of food processing, in particular to a two-phase extraction deacidification refining method for rice bran oil. Background technique [0002] Rice bran, a by-product obtained during rice processing, is a kind of rice oil obtained by pressing or leaching. Currently, it is NY / T122-1989 (current domestic) standard "rice bran" (about 18% oil, composed of rice husk, dust The GB19112-2003 standard prepared from , microorganisms and secretions, pericarp, seed coat, exosperm, aleurone layer, embryo, etc.) can be used for edible "Rice Bran Oil", because this standard rice bran oil is rarely used for food, and it is often used Used in the manufacture of feed, soap, hardened oil, glycerin, stearic acid, oleic acid, paint resin and other industrial raw materials. [0003] At present, crude rice bran oil is usually prepared by pressing or leaching, and contains impurities such as phospholipids, free fatty acids, pigments...

Problems solved by technology

[0004] Aiming at the deficiencies of the prior art, the present invention provides a two-phase extraction and deacidification refining method for rice bran oil, which has the advantages of circulation filtering function and pressing function, and solves the need to filter rice bran crude oil before actual use in the existing refining system , but the existing filter mechanism cannot filter efficiently, resulting in a large amount of small impurities mixed in the rice bran crude oil, which affects the subsequent process. At the same time, a large amount of rice bran crude oil will remain in the filtered residue, while the existing filter Institutions are unable to collect this crude oil, resulting in resource loss
