Rice Bran Pretreatment
Introduction of rice pretreatment:
Adopt the magnetic separation removing iron miscellaneous and vibration sieve removing broken clear, rice Xi, 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 mateial grain, and increases the materials bulk density, then improve the permeability and leaching rate which solvent reacts to the material.
The puffed rice bran contains about 12% water, and the best moisture for leaching process is 7-9%, therefore, there must be effective drying means to achieve the best leaching moisture.Adopting counter-current dryer can make water and temperature meet with follow-up process requirements, and improve the oil yield, as well as oil quality.
Features of pre-treatment workshop:
1.Different combinations of process can process various oil plants in one workshop.
2.Use special intensified pretreatment technology for aroma peanut oil to make it more aroma.
3.Adopt advanced and reliable shelling technology to meet higher requirements for protein content in meal.
4.Extrusion treatment is used for raw materials with hard extraction, large-sized powder, and large capacity, which can reduce residual oil and solvent consumption, and increase the capacity by 50-80%.
