Rice Bran Oil Production Line

Clean out the sand, broken rice, straw ropes, plant straw, and other debris contained in the rice bran to avoid damaging or clogging the extraction equipment and affecting the oil yield. At the same time, the rice bran must be preheated in advance to adjust the moisture and temperature of the rice bran to achieve a suitable state for oil production.

Feed the pretreated rice bran into the puffing machine. The powdered rice bran undergoes high pressure, friction, expansion, etc. to change the shape of the rice bran and polymerize it into a porous and air-permeable columnar shape. structure. After expanding, the cell tissue of rice bran is destroyed and the internal pores are larger, which is conducive to solvent extraction. Adopting expansion technology in the rice bran oil production line can increase extraction efficiency, reduce residual oil rate in the meal, increase the capacity of the oil extractor, reduce power consumption, and improve the quality of the extracted rice bran oil.

The expanding rice bran particles enter the extractor and are extracted with organic solvents to obtain mixed oil. The solvent is evaporated through evaporation and stripping to obtain crude rice bran oil. After rice bran oil is extracted by the solvent, rice bran becomes bran meal, which is evaporated by the solvent and becomes the finished meal.

Huatai rice bran refining process uses physical refining, including hydration degumming, washing, drying, decolorization, filtration, deacidification, deodorization, dewaxing, and other processes. The rice bran refining device developed and produced by Huatai Oil Machine can reduce the refining amount of caustic soda and activated carbon, and can also reasonably reduce the peroxide value to avoid oil discoloration and acid return in the process of high-temperature deodorization.
