Pretreatment Plant Introduction
Rice bran extrusion flowchart:
Rice bran→Magnetic separation→Rice bran and fine broken rice separation →Extrusion Puffing→flat plate drying →to extraction plant
Main process description:
Adopt the magnetic separator to remove metal impurities, ensure the machines’ long service life and fine products. And use rice bran and fine broken rice separation sieve (Chaff rotary sifter)to remove broken rice, fine broken rice etc.
Adopting the bulking machine can both improve the yield of rice bran oil and reduce the consumption. The extrusion puffing, on the one hand, can make solution lipase in the rice bran passivated under high temperature and high pressure condition,then prevent the rice bran oil rancidity; On the other hand, the extrusion puffing can make rice bran be porous material grain, and increases the materials bulk density, then improve the permeability and leaching rate which solvent reacts to the material.
