Rice bran oil dewaxing production line, dewaxed crude bran oil and vegetable oils such as general relatively rapeseed oil, soybean oil, peanut oil, etc., not only the acid prices, color depth, but also contains 2% to 7% wax. Rice bran wax called "bran wax." It waxes and mineral composition is different, which is a long-chain n-alkanes, and the main ingredient is rice bran oil plant （http://www.ricebranoilplant.com）bran wax esters of higher fatty acids in the form of higher fatty alcohol.
At higher temperatures, bran wax molecules dissolved in oil dispersion state. Because of its high melting point, when the temperature decreases, the oil phase will be crystallized, the oil was opaque and affect the appearance of the grease. At the same time, high wax content of rice bran to eat paste mouth, affecting appetite, can not be absorbed into the human body for the body to digest, it is necessary to be removed. Also need "dewaxed" oil production when corn salad. Removal of wax in the oil process referred to as "dewaxing."Defatted rice bran oil dewaxing method of now, there are three: a filter press method, bag hanging filtration and centrifugation. The so-called lifting bag filtration, deodorized oil is to be pumped into a condensate tank cooling crystallization crystallize, and then cooling the good oil into the bag, the bag hanging suspended, by gravity, oil flows from the bag bore, wax stay in the bag, so as to achieve oil wax separation. The resulting quality of refined oil this law is good, but labor-intensive, floor space is also large, refined oil was low, so the use of this method is now running out.
