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.

plam oil mill machinery introduction:
plam oil mill machinery main parts:
Pretreatment and oil press:
a. Palm fruit reception:Transport FFB to reception station, flow to the scraper conveyer, conveyed to sterilizing station.
b. Sterilizaiton: FFB transported by scraper conveyer fall into sterilizing tank, make FFB soft,get more oil yield. sterilizing time 90~120mins, temperature 130~145ÃÂ°C
c.Threshing: After sterilizing, fruit bunch transported to thresh machine, separate palm fruit and empty fruit bunch.
d:Digesting: Before press palm fruit, should be crushed separated pulp and kernel
e.Oil press: After crushing and digesting, the maxture of palm fruit and kernel fall into special palm oil presser
f.Clarification:Filter the oil and use centrifuge to separate oil and impurities.
g. Kernel recovery:After press, the kernel and cake will be transported to kernel recovery station. Separating nut and shell, then go to kernel oil press.
h.Palm kernel oil filteration: Use vibrating filter to filter the oil to remove impurities in it.
