This patent production line of rice bran pretreatment and expansion machines adopts reasonable designs. It can make high efficient expansion for rice bran. This rice bran oil expansion pretreatment is featured by high quality rice bran expansion, low human and production cost, small footprint, low power consumption etc.
Process flow of Rice Bran Oil pretreatment & Expansion introduction:
1. Rice bran was unloaded into workshop manually through artificial screw feeder and then be sent to elevator.
2. The uploaded rice bran goes through rice bran separating screen in order to remove large complexes of rice bran.
3. Clearly cleaned rice bran is sent into quenching pot through elevator conveyor. The quenched rice bran goes into feeding auger after expansion and fall into extruder.
4. After extruding, rice bran expansion materials fall on flat dryer for drying. The dry extruding rice bran is sent to extraction plant by conveyor.
Process Flow Chart of Rice Bran Oil Expansion & Pretreatment:
Working Principle of rice bran oil pretreatment and Expansion:
Rice bran oil expansion pretreatment will change the shape and structure of rice bran through press and promotion of non-isometric and nonstandard screw system of extruder. The gas among rice bran gap is squeezed out and quickly filled with materials, which causes rice bran sheared back and increased pressure inside the chamber. Rice bran hybrid is fully mixed, squeezed, heated, glued and pasted with increasing friction between screw and chamber, which changes rice bran structure and destroys rice bran fat layer structure.
At the same time, mechanical energy converts into heat, and machine chamber quickly rises to 125 degrees, which causes effective passivation of various enzyme activities of rice bran, and destruction of fat layer structure. The starch and protein turn into viscous state while rice bran is extruded to the exit, and high pressure changes into atmospheric pressure instantaneously. Moisture is evaporated from rice bran organizational structure quickly, forming into numerous pore structure inner rice bran. The rice bran oil expansion pretreatment is completed after cooling.
