Rice bran oil refining process main includes: degumming – dewaxing – deacidification – deodorization – degrease.
Today, mainly introduced rice bran oil deacidification, deodorization, degreasing process.
Due to contain more free fatty acid in rice bran oil, in order to ensure the deacidification and the deodorization effect, in order to avoid a lot of neutral oil saponification loss, adopting under the condition of high temperature and high vacuum, water vapor stripping methods to deodorization and removing acid at the same time, the physical refining deacidification process.Dewaxed oil come into the analysis degasser, removal sir in the oil,by the pump into oil–oil heat exchanger, heating rice bran oil.High temperature rice bran oil into the filler flash column to stripping deacidfication for the first time, and then enter the decelerator high temperature to decomposition pigment.Stay after a period of time, heating rice bran oil, into the packing flash clumn for second deacidification, deodorization, to remove free fatty acid in rice bran oil more thoroughly removal.
Rice bran oil is different from other oil, which contains both wax, low temperature will has more solid fat, in the production of qualified first level rice bran oil, solid fat effective separation is the key process.rice bran oil after deacidification and the deodorization and the first level of rice bran oil from oil tank by pump, through the plate heat exchanger heat exchange, after cooling oil into the cooling crystallizer, controlled cooling crystallization.Then enter thehot write type filter press filter, in order to reduce oil viscosity, easy to filter, can be appropriately raise the temperature, filtered clear liquid oil is the first level of rice bran oil, rice bran solid fat is goog raw material for margarine and shortening processing.
