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.

Introduction of New technoloLD conttenseed oil fractionation project equipment, fractionation worshop equipment,Oil fractionation machine plant
1) Cottonseed oil fractionation
Cottonseed oil is one of the largest oil types, whose fatty acid is composed of 20%~22% palmitic acid, 30%~35% oleic acid, 40%~45% linoleic acid. The melting point of cottonseed oil is 10~15.6 ÃÂ°C. As the high-grade edible oil, cottonseed oil is not widely used in winter because of its easy turbidity caused by higher melting point, so its price is also low. By fractionation, liquid and solid oil can be obtained, which can increase oil' added value and edibility.
2) Separation of mixed fatty acids
According to the carbon chain length of fatty acids, separate short carbon chain (C12), medium carbon chain (C14) and long carbon chain (C16, C18) by vacuum distillation, and then separate the saturated fatty acid from the unsaturated fatty acid. Owing to the little boiling point differences between them, they can't be fully separated and also will has high production cost. Our company uses dry fractionation to separate the mixed fatty acids into various fatty acids of different melting point and application.
