What is the oil extraction ?
Extraction is a chemistry way to extract oil from soybean . It makes use of Solvent Extraction Principles ,which makes Number 6 solvent oil come into soybean cake .Then oils and fats is dissolved from Mixed oil.
Principle of oil extraction
make use of solvent that it can dissolve in the oil and fat ,extacting oil from oil cake ,by moist and penetration,molecule spread and convection work .
How to extact oil from the cake ?

Solvent recovery
The process of oil extraction
1. The oil pre-pressed will be put in the leaching plant .Then we add NO.6 solvent oil .
let oil commbined with solvent .The temperature of solvent should be 55-60degree . Then by heating ,through the frist steam pipe ,second steam pipe ,then stripping tower .the solvent will come out from the cake with oil .We heat them , the solvent will change to gas to go ,lefting the oil .
2. As the solvent with some oil and water ,in order to recycle solvent ,we must make it cooling .So we need the condenser .The condenser change solvent to liquid . we seprate the solvent ,oil ,water .And we can recycle solvent .
Factors of affecting extracting oil
Performance of Pre-pressed cake structure and moisture of oil cake
extraction temperature Less than about 5 degrees of initial boilingpoint
Extraction time 90-120 minutes
Height of bed of material try to elevate it
ratio of solvent and Mixed oil concentration 0.8-1:1 , 18-25%
Drain time and wet meal with the amount of solvent 15-25min 25-30%
Process of mixed oil evaporation and stripping
mixed oil filter - mixed oil store - first Evaporator - second Evaporator - stripping tower - leaching oil
Raw material
sesame ,soybean , peanut , rapeseed ,cottonseed , plam kernel ,olive ,Jatropha , rice bran ,sunflower seed etc
