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.

1. Cleaning process : Use vibration cleaning sieve and magnetic selector to get better cleaning effect.
And This step is mainly to clean the big impurities ,lLD the stone , big dust , iron etc .
2. Crushing Process: This Process is mainly to crush the peanut , as the peanut is big ,it is not easy to press .
We must crush the peanut to 6-8 pieces . Then we need to peel . The rate of peel is about 90% .
3. Flaking Process : After crush and peel ,we need to flake the crushed peanut , which make the cell wall of
peanut broken . And we flake the peanut to 0.55 mm thickness . Then it is useful for the oil extracting .
4. Cooking Process: After the flaker,we need to cook the flaked peanut , control the moisture at 5-7% ,
the temperature is 110-115degree .
5. Pre-pressing : After all the pretreatment , pre- press the peanut , the oil can be extracted about 76% .
2.Solvent extraction section of edible oil production machinery line,edible oil equipment production line,edible oil extraction machine production line
After pre-pressing process , the requirement of peanut cake : moisture is about 8%, the residual oil :18-22% .
Use solvent organic solvent through soaking or spraying contact methods to extract oil from the cake. There is only
less 1% oil content in meal after oil extraction machine .
Remark: The extraction workshop must be in a separate yard . This yard should be have at least 1.5 m
high brick wall all around ,the walls is 12 meters far from extraction workshop. Fire district : at least 30 meters
far from residential area, keep from fire .
3.Oil Refining Machine of edible oil production machinery line,edible oil equipment production line,edible oil extraction machine production line
Oil refining is according to the different usage and requirements, utilizing the physical methods and chemical
processes to get rid of the harmful impurities and needless substance in the crude oil, getting standard oil.
The crude vegetable oil from above mentioned two ways of extracting, oil pressing and/or solvent extraction,
will be pumped into oil refinery units to produce cooking oil at various grades.
These processes include neutralization (removing free fatty acid), degumming, decolorization (bleaching),
deodorization.Then you can get first grade groundnut/peanut oil .
