Type: Rice Bran Oil Pretreatment & Extrusion Processing Plant
Productive Capacity: 30-3000 Tons per day
Processing Material: Rice Bran
Major Equipment: Vibrating Screen, Magnetic Separator, Softening Machine(Conditioner), Extrusion Machine, etc.
Application: High efficiency rice bran extrusion process, Granulation for preparation of Rice Bran Oil Extraction Process.
The pretreatment process mainly consists of cleaning section, rice bran and tips separation machine, rice bran softening and conditioner and rice bran extrusion machine. This patented production line of rice bran pretreatment and extrusion machinery adopt the reasonable designs. It can make high efficient extrusion for rice bran. The rice bran oil extrusion pretreatment line is featured by high quality rice bran extrusion effect, lower manpower and production cost, small floor space, low power consumption, etc. Process flow chat of Rice Bran Oil Pretreatment & Extrusion Processing introduce as follows: Rice bran cleaning →softening →extrusion →drying →to extraction workshop
Cleaning Process: Adopting the magnetic separator to remove iron impurities, rice bran and fine broken rice, separation sieve to separate rice bran and fine broken rice.
ExtruTFsion Process: Adopting the Extrusion Machine can both improve the yield of rice bran oil and reduce the consumption. The extrusion puffing, on the one hand, can make the lipase in rice bran to be passivated under the high temperature and pressure condition, then to prevent the rice bran oil from rancidity; On the other hand, the extrusion puffing can make rice bran to be porous grain to increase the materials bulk density, and improve the permeability and extraction rate that the solvent reacts to the material.
Drying Process: The puffed rice bran contains about 12% water, but the best moisture for Rice Bran Oil Extraction Plant is 7%-9%. Therefore, there must be effective drying ways to achieve the best extracting moisture. The counter-current dryer can make water and temperature to meet with the following processing requirements quickly, meanwhile to improve the oil yield as well as oil quality.
1) To create a good production environment;
2) To minimize the total fat loss, increase oil yield and output and improve the quality of oil and cake meal;
3) Comprehensively to utilize impurities and offal;
4) Perfectly to match extraction production line, design different production processes according to different materials.
