How to produce rice bran oil?
1. Rice bran oil pretreatment machines
Rice bran oil pretreatment machines are used to process the rice bran into best conditions for achieving better effect of solvent extraction. the Rice bran oil pretreatment machines includes chaff rotary sifter, conditioner, puffing machine and plate dryer.
a. Chaff rotary sifter: to separate the rice bran and broken rice.
b. Conditioner: to adjust the moisture and temperature of rice bran.
c. Puffing machine: to change the inner structure of rice bran, make it softer and more easily to extract oil by solvent.
d. Plate dryer: to cool and dry the rice bran, make it store for long time, avoid becoming rancidity quickly.
2. Rice bran oil solvent extraction machines
Rice bran oil solvent extraction machines have four systems: Solvent extraction system, D.T.D.C system, mixed oil evaporation and stripping system and solvent cooling and recycling system.
The advantage of solvent extraction method is that it can make the residual oil rate less than 1%, and make the benefit maximum. Though the machine cost is higher than oil pressing plant, the production cost is much lower than that. So solvent extraction method is the most suitable method to produce rice bran oil.
3. Rice bran oil refining machines
Rice bran oil refining machines is used to refine the crude rice bran oil into refined product oil. It has three type: batch type, semi-continuous and full-continuous type.
The rice bran oil refining process generally consists of five processes: degumming, deacidification, decolorization, deodorization and dewaxing. The function of the rice bran oil refining process is to remove the different kinds of impurities and retain the nutritional ingredient and make the final product oil reach Grade 1 Level.
From rice bran pretreatment to crude rice bran oil refining process, it is a complete production line. If you want to produce crude rice bran oil and want to sell it to other oil refinery plant, you needn’t buy the rice bran oil refining machines. Or if you already have a crude rice bran oil processing plant and want to further process the crude rice bran oil into refined oil, also welcome you contact Henan Huatai Oil Machinery. Our engineers can give you suitable suggestions based on your requirement.
