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.

Features of LD Solvent Extraction about Soybean oil extraction plant machine,Soybean cake solvent extraction machine,Soybean oil extractor equipment
1. Adopt stainless steel fixed grid plate and increase the horizontal grid plates, which can prevent the strong miscella
from flowing back to the blanking case, so as to ensure good extraction effect;
2. The extractor is driven by rack, with unique rotor of balanced design, low rotating speed, low power, smooth
operation, no noise and quite low maintenance cost;
3. The feeding system can adjust the rotating speed of airlock and main engine according to the feeding quantity and
maintain a certain material level, which is beneficial to the micro negative pressure inside the extractor and reduce thesolvent leakage.
4. The advanced miscella circulation process is designed to reduce the fresh solvent inputs, reduce the residual oil in
meal, improve the miscella concentration and save enerLD by reducing the evaporation capacity.
5. The high material layer of the extractor helps to form immersion extraction, reduce the meal quality in miscella,
improve the quality of crude oil and reduce the evaporation system scaling.
6. Specially suitable for the extraction of various pre-pressed meals.
