Rice bran extrusion


Adopting the bulking machine can both improve the yield of rice bran oil and reduce the consumption. The extrusion puffing, on 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.
