Abstract

The invention discloses a method for filtering and removing rubber from rubber seed oil by utilizing a high-efficiency membrane. The method comprises the following steps: heating rubber seed crude oil, applying pressure, enabling the heated rubber seed crude oil to pass through a ceramic filtration membrane with the aperture of 80-200 nm, heating the filtered rubber seed crude oil, applying the pressure, and enabling the heated rubber seed crude oil to pass through a ceramic filtration membrane with the aperture of 5-30 nm to obtain the filtered rubber seed oil which removes polyisoprene. According to the method for filtering and removing the rubber from the rubber seed oil by utilizing the high-efficiency membrane, a membrane filtering method for removing trace polyisoprene molecules in the rubber seed oil is pioneering and is a pure physical method which is completely different from the existing chemical method; two-stage filtering is utilized, so that the membrane efficiency is largely improved. The conventional idea that membrane filtration is hard to be applied to vegetable oil from the skilled persons in the art is broken; besides, by limiting two special apertures, the purposes of completely removing the polyisoprene and obtaining high filter efficiency are achieved, and the problems that chemical agents are necessarily imported and other beneficial trace elements are easy to remove in the prior art are solved.

Description

technical field [0001] The invention relates to a method for removing rubber by high-efficiency membrane filtration of rubber seed oil, and belongs to the technical field of vegetable oil removal and refining. Background technique [0002] Rubber seed oil is a vegetable oil extracted from the seeds of the rubber tree, which belongs to the precious tropical tree nut oil. Rubber seed oil does not contain any toxic ingredients, and its fatty acid composition is common fatty acids, mainly palmitic acid, stearic acid, oleic acid, linoleic acid and linolenic acid, accounting for more than 99.5% of its fatty acid composition, without any Special inedible fatty acids. The unsaturation (total unsaturated fatty acids) of rubber seed oil is as high as 83%, and it is especially rich in linolenic acid (omega-3 fatty acid), which is scarce in the diet of Chinese residents, with a content as high as 20%. Studies by many research institutions at home and abroad have shown that rubber seed...
