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 Rice bran oil making machine plant,Rice bran oil refinery machine workshop,rice bran oil refining equipment

1) The main function of decoloring process is to remove oil pigment, residual soap grain and metal ions.
2) Under negative pressure, the mechanical mixing method combined with steam mixing

will improve the decoloring effect.
3) The degummed oil firstly enters into the heater to be heated to the appropriate temperature (110°C), and then goes to the bleaching earth mixing tank.
4) The bleaching earth is delivered from the low bleaching box to the temporary tank by wind.
5) The bleaching earth is added by automatic metering and is interlockingly controlled with the oil.
6) The oil mixed with the bleaching earth overflows into the continuous decolorizer, which is stirred by non-powered steam.
7) The decolored oil enters into the two alternate leaf filters to be filtered.
8) Then the filtered oil enters the decolored oil storage tank through the security filter.
9) The decolored oil storage tank is designed as the vacuum tank with the nozzle inside, so as to prevent the

decolored oil contacting with the air and influencing its peroxide value and color reversion.
