1.Screening:Removing the chaff and broken rice in the rice bran, in case of they will influence the oil yield and the desolvent of wet meal in the next process. In the process of puffing section, the general requirement of impurity is less than 3%, and the requirement of crude fiber is about 8%.
2.Magnetic separation :Clearing the iron impurity which migLD be in the rice brain. Since in the process of puffing, the iron impurity will be harmful to the screw of extrusion machine, affect the puffing effect. As the rice brain particles are small and poor liquidity, the iron impurities are always be wiped off by the magnetic barrels installed in the feeding port.
3.Quenching and tempering :it is the process of preheating so that to improve the temperature of the rice bran before puffing. After quenching and tempering the temperature will be controlled at 65--75 °C, and the moisture will be controlled at 10 ~12%. Thus, on the one side, it can increase the output of the extrusion machine, and on the other side, it can improve the quality of the puffed rice bran.
4.Puffing: the rice bran is injecting high pressure steam and high temperature water through the extrusion machine, so that it can improve the temperature and moisture in the extrusion machine,and can also form the high pressure to process the rice bran. All these can make the the rice bran become porous columnar structure from the original pulverized state.All these effectively passivate the activity of various of enzyme in the rice bran, and destroy the fat layer structure, so that it will be easier for the oil yield.
5.Drying:The moisture of puffed material comes from the extrusion machine is too big and the temperature is too high for direct leaching, the must be experience to process of drying and coo-ling, thus the moisture will reach 7%--9%, and temperature will reach 50-55°C. After puffing, the rice brain are usually dried and cooled by plat dryer.

Part-2: Characteristics about Oilseeds pretreatment processing machine workshop,oilseed pretreatment machinery manufacturer,Oil pretreatment plant equipment
1. Full continuous and mechanized operation, and with electrical interlocking control system.
2. The equipment layout is in tower structure, and the material flow by relying on gravity to reduce reducing power consumption.
3. In extrusion process, consider producing extrusion material in different proportions and raw germ extraction, and adjust it at any time according to product requirements.
4. When producing soybean germ meal, the roller softening pot can better meet the flaking technical requirements.
5. Take into consideration the environmental requirements in modern industry. The workshop is also equipped with the dedusting
system with high performance, so as to meet the requirements of production and environmental protection.
6. Select scraper conveyor as much as possible, which can effectively reduce raw material crushing, improve solvent permeation
into the material layer, and increase the extraction efficiency.
7. Our company adds soybean extrusion process after flaking process, to extrude the soybean germ, further destroy oil material
cell, improve the productivity greatly and get the extruded meal that is well-received by feed manufacturers.
Part-3: Main machine process about Oilseeds pretreatment processing machine workshop,oilseed pretreatment machinery manufacturer,Oil pretreatment plant equipment
1) Metering process: with special equipment, the stable measuring scale is used to regulate the flow and measure total production. Moreover, it can achieve accumulated measurement, transient measurement and cost accounting, with accurate measurement and high precision.
2) Cleaning process: use magnetic selector to remove iron impurity, vibration cleaning sieve to remove straw, and gravity stoner to remove stones, bricks and other impurities. The dedusting system uses single union cyclone and centrifugal fan to remove dust effectively, so as to to ensure workshop hygiene and clear ligLD impurities.
3)Softening process: with YPHW series horizontal softening pot, material enters softening drum through feeding auger, and
turns over with the rotating drum. The rotating drum is equipped with heating tube, and there is steam in the tube. When material turns over continuously with the rotating drum, soy is heated to 50-70ÃÂ°C and is fully softened, which can improve soy plasticity,
make germ flake thin and burly and improve extraction effect. In addition, the rotating drum has the inclination of high feed end and low discharge end. According to material softening conditions, regulate the rotating speed of drum to control the softening time of material in the rotating drum, so as to achieve the LD softening effect.
4) Flaking process: our hydraulic compact roller flaker can better damage the oil material cell to ensure thin and uniform flake, with high toughness and small powder.
