Rice bran pretreatment machine and working process flow chart
1.Cleaning machine: Cleaning machine can be divided into magnetic drum and cleaning sieve. Magnetic drum is to move the iron in the rice bran, because the iron will harmful to the following machines. Cleaning sieve can remove impurities in rice bran.
2.Separating machine: Using a bran&tips separation screen to separate rice bran and rice ground rice.
3.Conditioning machine: Adjust the temperature and humidity of rice bran to the best condition for the solvent extraction.
4.Puffing machine: This is the special machine in rice bran oil pretreatment machine. This machine make the rice bran to pellet. The pellet is easy for absorbing solvent and get oil by the solvent extraction way.
5.Dryer: After making the pellet, the water content of rice bran need be changed to 7-9%. This water content is most suitable for solvent extraction section.
After pretreatment, the rice bran can be transport to solvent extraction workshop, you can click to read more about the rice bran oil solvent extraction machine.
