Main features: The rice bran oil refining machine adopts the physical refining process. It does not need to deacidify by alkali refining, avoiding the loss of neutral oil and greatly reducing the production cost. Rice bran oil refining equipment manufacturers arrange the dewaxing process prior to decolorization. Due to the high content of fatty acids in the oil, and the higher melting point of the fatty acids and the lower temperature, some fatty acids can be solidified first, resulting in a sharp rise in the viscosity of the oil. The acid value is 30 (KOH)/(mg/g) of oyster sauce, and the temperature drops to 20 . It has become very viscous at C, causing difficulty in dewaxing filtration. Therefore, the acid value of rice bran oil is dewaxed, and the filtering temperature should not be lower than 20. C.
The process used for dewaxing is as follows: The vacuum-dehydrated eucalyptus oil is poured into a crystallization tank and cooled under slow stirring to make the oil temperature about 24 hours from 70. C slowly and evenly dropped to 25. C, continue to stir slowly, and maintain the oil temperature unchanged, the growing of crystals, the growing time of more than 48h, after the end of crystal growth with a leaf filter pre-coated silicon bath soil for filtration. The oil quality should be kept at 25 during the filtration process. C does not change. Increased filter temperature can speed up the filtration efficiency and reduce the oil content of the wax paste. However, the wax content in the dewaxed oil will increase, the cloud point will increase, and the transparency will become worse. When the filtration temperature decreases, the amount of wax in the oil can be reduced. , Lower cloud point, increase transparency, but will significantly reduce the rate of oil filtration, and increase the wax paste oil content. When practicing the table: The dewaxing temperature of rice bran oil with an acid value of 20-30 (KOH)/(mg/g) is controlled at 20-25. C, the overall effect is better
