The feature of rice bran oil decides that the wastage of the traditional alkali refining is big and refining cost is high. So physical refining technology and equipment are utilized, which include 12 processes. The acid value for the first grade rice bran oil is less than 0.2mgKOH/g, color is less than Y20, R2. Refrigeration test meet the market demand, acid value of mixed fatty acid is150-190mgKOH/g.
Our combined deacidifying-deodorizing tower and rice bran oil physical refining technology can reduce the consumption of sodium hydroxide and active carbon; it also can effectively bring down oxidation value, and avoid color and acid returning during deodorization in high temperature, the production cost is low, acid value of fatty acid is high and trapping effect is good.
Crude Oil — Degumming — Drying — Discoloring — Filtering — De-acidifying — Deodorizing — Dewaxing — Degreasing — Final edible rice bran oil
● Physical technology is adopted, advanced degumming technology is employed together with rich dewaxing and degreasing experiences, which can produce first grade rice bran oil with low cost and achieve the fatty acid with higher purity.
