What is the oil extraction ?

Extraction is a chemistry way to extract oil from Rapeseed cake . It makes use of Solvent Extraction Principles ,which makes Number 6 solvent oil come into rapeseed cake .Then oils and fats is dissolved from Mixed oil.

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 boiling point

Extraction time 90-120 miunts

Height of bed of material try to elevate it

ratio of solvent and Mixed oil concentration 0.8-1:1 , 18-25%

Drain timeandwetmeal with the amount ofsolvent 15-25min 25-30%
