Cotton is grown in many parts of the world, but is mainly produced in China, Uzbekistan, the United States, India, Egypt and Turkey, and is one of the common oil crops. Cottonseeds with hulls contain 17-20% oil and cotton seeds without hulls contain 33-40% oil. So how to get cottonseed oil from cottonseed? What machines are needed in cottonseed oil extraction process?
In general, there are two methods for producing cottonseed oil. The first method is direct press and the second one is pre-press & solvent extraction. The second method is suitable for large scale cotton seed oil mill plant, because it can make sure the residual oil rate less than 1%。
First, direct press
Direct press includes cleaning, husking, crushing, softening, flaking, cooking, pressing, etc. process to adjust the cottonseed into the best condition for oil pressing and easy to press oil out. The complete set of equipment for cottonseed oil using direct pressing involves cleaning machine, husking machine, kernel and shell separating machine, flaking machine, cooking machine, pressing machine and filter machine to obtain crude cottonseed oil.

Second, pre-press & solvent extraction
Pre-press & solvent extraction refers to that after pretreatment, the cottonseed is pressed by the oil pressing machine, then send the press cake to solvent extraction plant to further process. Generally, by using the extraction way, the oil residue will be lower than 1%. Solvent extraction equipment includes solvent extraction system, D.T.D.C system, condenser system and recovery system. Besides, the crude cottonseed oil obtained either from direct press or pre-press & solvent extraction plant contains some harmful impurities, so we also offer cottonseed oil refinery plant to get rid of the impurities. It aims at improving the flavor and color of oil and get standard quality edible oil. Cottonseed oil refining process includes degumming, deacidification, decolorization and deodorization.
