How to make cottonseed oil in cottonseed oil processing factory? The whole set of cottonseed oil processing plant can be divided into three workshops: cottonseed pretreatment and oil pre-pressing workshop, cottonseed oil solvent extraction workshop and crude cottonseed oil refinery workshop.
1.Cottonseed pretreatment and oil pre-pressing workshop
In the manufacturing process of cottonseed oil, cottonseed pretreatment is the first step. Cottonseed should be cleaned, processed by some machines to reach the most suitable conditions for pre-pressing.
The whole cottonseed pretreatment and oil pre-pressing manufacturing process includes cleaning, shelling, kernel and hell separating, flaking, cooking and pre-pressing.
2.Cottonseed oil solvent extraction workshop
After pre-pressing, the cakes of cottonseed has more residual oil. So using cottonseed oil solvent extraction process can extract more oil from the cakes of cottonseed, which can make the residual oil rate less than 1%.
The whole cottonseed oil solvent extraction manufacturing process contains four sections: oil solvent extraction, wet meal desolventizing and drying, miscella oil evaporation and stripping, and solvent condensing and recycling.
3.Crude cottonseed oil refinery workshop
According to different capacities and refining technology, the crude cottonseed oil refinery machine has three types: batch type, semi-continuous and full-continuous type.
The crude cottonseed oil refinery manufacturing process is made of four steps: degumming, deacidification, decolorization and deodorization.
