In refining workshop, the extracted crude rice bran oil become 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 in one hour. Add acid or alkali to separate according to the acid value. After one hour’s processing and 4-6 hours deposit, then to 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 to separate clay and oil with filter.
3. Put 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:
(1) Refining section: to P-acid de-gumming, alkali refining de-acid and water rinsing.
(2) Decoloring section: to remove off pigments, bleaching oils and grease dehydrate.
(3) Deodorizing section: to remove off the odor components in oil.
(4) Dewax: to remove off the wax in the oil, in order to get the high quality oil.
(5) Heat-transfer oil stove: to supply each device needing heat energy, temperature to reach above 280°C.
(6) Steam generator: to produce the needing steam for de-odoring and distillation.
(7) Vacuum pump: to supply needing vacuum for dehydrate, de-color, de-odor. Vacuum degree can reach above 755mm Hg.
(8) Press filter: to filter clay and get clear oil.
(9) Air compressor: blow dry bleached clay, blow empty the leftover oil in the press filter.
