Rice Bran Oil Processing Line


Rice Bran Oil Machine Introduction:
 
Rice bran→Magnetic separation→Cleaning →Extrusion Puffing →Counter-current
 
Main process description of Rice Oil Mill Machinery:
Cleaning process:
Adopt the magnetic separation removing iron miscellaneous and vibration sieve removing broken clear, rice Xi, etc.
 
Expanding process:
Adopting the expander 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.
Drying process:
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.
 
Process feature:
1.Different combinations of process can process various oil plants in one workshop.
2. 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%.

Automatic Control System of  Rice Bran Oil Machine  
 
Our company has applied the automatic control system with advancedness, security, reliability into the pretreatment, extraction, refining and fractionation in large oil plants. For its application in automatic control system, it can control the production in the entire workshop and monitor the operational status of each device by controlling the computer terminals in the room. One person only can operate the entire workshop, with efficient production management. It has reduced the production cost greatly and improved the management efficiency.
