In refining workshop, the extracted crude rice bran oil become product rice bran oil by special processing to get rid of impurities, wax, gums, FFA, pigment and odors. Refinery usually includes degumming, deacidification, neutralizing,bleaching, deodorizing, dewaxing, fractionation and other sections.The refining method of rice bran oil refinery plant:Chemical refinery,Physical refinery,Chemical &physical combination refinery.Working process of rice bran oil refinery plant:1.Pump crude edible oil into refining tank and heat with conduction oil, and the temperature will reach about 70°C-80°C after one hour. Add acid or alkali to separate according to the acid value. After one hour’s processing and 4-6hours deposit, then convey soap stock to storage tank. 2.Pump refined oil into decoloring tank. When it is up to 90-110°C after one hour’s heating, add clay into tank for 20min’s processing. Then separate clay and oil with filter.(3Put decolorizing oil into deodorization tank with vacuum pump. Heat and process with steam for odor removal. After filtering, you will get final oil product. The main process of rice bran oil refinery plant:Crude oil,Degumming,Deacidification,Bleaching,Frame filter,Deodorization,Dewaxing,Leaf filter. Rice bran oil refinery plant Main parts:
