In order to obtain high quality refined rice bran oil, the refining process begins by reducing excess free fatty acid and then decreasing the color with activated clay. After decreasing color, the oil is forwarded to the crystallization process before filtering the wax through a filter press machine.
What is rice bran?
Rice bran is a byproduct of the rice milling industry obtained from milling of brown rice to produce white rice. It contains 15%?20% of oil. Apart from oil, rice bran is a promising source for proteins, carbohydrates, dietary fiber, vitamins, tocopherol, γ-oryzanol, and phospholipids ( Tao, 1989; Houston, 1972; Saunders, 1986 ).
What is the output rate of rice bran oil mill machinery?
The output rate of rice bran oil mill machinery is between 8-11% and the capacity is from 5t to 100t per day. In order to obtain high quality refined rice bran oil, the refining process begins by reducing excess free fatty acid and then decreasing the color with activated clay.
What is rice bran wax used for?
Some industrial manufacturers also used it for oil recovery. However, the recovered oil was utilized for nonedible applications. In addition, a few researchers ( Prasad et al., 2008, Prasad et al., 2009) developed a process for the upgradation and bleaching of crude rice bran wax.
