1. Formal oil pressing can adopt one time or twice pressing of oil seeds. It is applicable for low capacity required oil processing oil plant. 
2. High capacity oil seeds pretreatment and oil pressing equipped with oil extraction treatment, is used in high capacity and large-scale oil pressing plant, or high oil content oilseeds processing plant (/index.php?u=show-1449.html). 
3. Oil prepressing can get up 70% oil fat of embryo, and residual oil inside pre-pressed cake can be extracted by organic solvent.

Crude oil → degumming and deacidification→ decolorization →deodorization → refined oil

1. Degumming and deacidification: The gumming is moved by phosphoric acid and hot water. There are two ways to move the acid in the crude cottonseed oil. 

2. Decolorization: This step is used to adjust the color of the oil. You can control the color of the cottonseed oil according to the requirement of your market.

3. Deodorization: The function of this step is to move the special smell in the oil.This is an important standard for refined cottonseed oil.
