Cottonseed oil is a widely used edible oil in the world. It is produced as a byproduct of the cotton planting industry. The oil content of the shelled cottonseed kernel is close to 40%, which contains a large amount of essential fatty acids for the human body. The most suitable way to eat it is to mix it with animal fat. Cottonseed oil has a high content of linoleic acid, which can effectively inhibit the rise of cholesterol in the blood and maintain human health. The absorption rate of cottonseed oil by the human body is 98%.(Related Post: Cottonseed Oil Press Machine In Uzbekistan Price >>)
The processing steps of cottonseed oil processing plant from pre-pressing, extraction to refining:
1. Cottonseed oil pre-press:
Nude cottonseeds → screw conveyor →magnetic separator → vibrating screen →destoner→ husking →cooking → pre-pressing→ cake for extraction and crude oil directly for refinery
B. Points for cottonseed oil prepress plant :
♦ If your raw material is not nude cottonseeds , then you need add delinting machine.
♦ Magnetic separator, vibrating screen ,destoner are used to remove different impurities inside cottonseeds depending on different specific gravity.
♦ Cooking is preparing for pre-press, normally is about 30minutes, 105-110℃.
♦ Pre-pressing only part of cottonseed oil, which will save energy consumption.

Pre-pressed oil cake → Extraction →wet meal → desolventizer →Cooling → dry meal for animal feed
Mixed oil →filter → evaporation →Crude oil
B. Key points of cottonseed oil extraction plant
♦ Oil pressing is to extract oil from oil cake using solvent, and the oil cake is carried out in the oil press. There are many types of oil presses: ring oil press, rotary oil press, drag chain oil press, etc.
♦ Smoking is prohibited in the oil pressing area, and all machines, especially motors, are explosion-proof.
♦ The wet meal is dried and separated from the solvent in the desolventizer, and the dried meal is packaged and sold.
♦ The mixed oil and solvent are separated by multi-effect evaporation, which has normal pressure evaporation and negative pressure evaporation. Negative pressure evaporation is more energy-efficient.
♦ We provide dephenolized cottonseed protein deep processing technology. Please contact us for more information.
3.Cottonseed oil Refinery Plant :
A.Flow chart:
Degumming →Deacidification →Decoloration → Deodorization →edible oil
B. Points for cottonseed oil refining plant
♦ Cottonseed oil refinery can be divided into batch refining (<20t/d), semi-continuous refining (20-50 t/d) and continuous refining (>50 t/d) depending on capacity. For 30-50 t/d , you also can choose continuous refining as your own requirement.
♦ For new harvest cottonseed , the acid value of crude oil is lower and the color is lighter , which is easier for oil refinery. If raw cottonseed is not in good quality after long storage, the acid value will be much higher and color is deeper, then maybe need twice alkali refining.
♦ Winterisation is optional depending on your requirement.
We have extensive practical experience in cottonseed oil processing, both in the fields of oil extraction and oil refining. We have established many cottonseed oil manufacturing plants in many countries, including India, Afghanistan, Pakistan, etc. If you want to start a cottonseed oil production business, please contact us immediately and tell us your requirements and capacity. We believe you can get more than expected benefits.
