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 .
Process of mixed oil evaporation and stripping
Mixed oil filter - mixed oil store - first Evaporator - second Evaporator - stripping tower - leaching oil
