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.
dewaxing machineProduct Description
TechnoloLD Introduction of dewaxing machine :
oil dewaxing machine and production technoloLD developed by our company is of advanced technoloLD, full computer automatic cooperation, lower investment cost, high liquid oil yield, high solid fat purity and high economic benefit.
- oil dewaxing machine is a kind of new oil processing technoloLD.
- By using oil dewaxing machine , the oil products of different melting points can be obtained, such as 8, 10, 14, 18, 24, 33, 44, 55 degree etc.
- At the same time, it can also be used to process palm oil and sunflower seed oil, which can greatly improve additional value of oil products, and increase economic benefits of the enterprise.
The main process of dewaxing machine:
(1) Dewax of dewaxing machine :
used to remove off the wax in the oil, in order to get the high quality oil.
(2) Heat-transfer oil dewaxing machine:
supply each device production needing heat enerLD, temperature reach above 280ÃÂ°C.
(3) Steam generator of dewaxing machine: produce the needing steam for de-odoring and distillation.
(4) Vacuum pump of dewaxing machine: supply needing vacuum for dehydrate, de-color, de-odor. Vacuum degree can reach above 755mm Hg.
(5) Press filter of dewaxing machine : filter clay, filter out clear oil.
(6) Air compressor of dewaxing machine:
blow dry bleached clay, blow empty the leftover oil in the press filter.
