What is the oil extraction ?
Extraction is a chemistry way to extract oil from cotton . It makes use of Solvent Extraction Principles ,which makes Number 6 solvent oil come in cotton 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 .

The process of cotton oil extraction
The prepared material enters the solvent extractor through the rotary air seal.
The solvent extractor consists mainly of a very slow moving articulated band conveyor inside a totally enclosed chamber.
The band is lined with perforated sheets and porous stainless steel cloth. The mass of the material moving on this band forms a slow moving bed.
During the movement of the bed through solvent extractor it is washed continuously at various points with miscella of decreasing concentrations
and finally with a fresh solvent in a counter current manner by means of sprayers kept in a line over the meal bed.
The miscella percolates through the perforated bottom and collects in various hoppers kept below the bed. The miscella from the last hopper,
which is concentrated, is taken off for distillation.
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 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
