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.
The process of groundnut 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
Principle of leaching method
Make use of a kind of solvent which can dissolve in the oil ,make oil extracted from the flake ,by moist and penetration ,molecule convection ,spread.
Process of this craft
Mixed oil filter - mixed oil stored - first evaporimeter - second evaporimeter - stripping tower - crude oil
Main raw material
Soybean ,peanut ,sesame ,rapeseed ,cottonseed ,palm kernel ,oilve ,corn , rice bran ,Jatropha etc
