Functions of each step of rice bran oil refining process:

1. Crude rice bran oil degumming:

In this step gums in crude rice bran oil are removed by hydration with the help of phosphoric acid.

2. Deacidification (neutralization):

In this step free fatty acids are neutralized by using sodium hydroxide and convert them into soap. Additional impurities are also removed by adsorption on soap.

3. Decolorization:

During decolorization, unwanted pigments are adsorbed physically and oil will become much clearer.

4. Deodorization:

Deodorization is used to remove unacceptable odors by steam distillation, the odoriferous compound are stripped off with the help of live injected steam into heated oil under high vacuum pressure.

5. Dewaxing (necessary for rice bran oil):

Rice bran oil dewaxing plant reduce wax content in rice bran oil, which help increase edibility of rice bran oil.

Advantages of rice bran oil refinery plant:

1. The impurity of oil must be less than 0.2% after refining;

2. Recycling system save power and money;

3. Lower oil waste.
