 As we know, cottonseed contains gossypol, which is bad for human especially for men. So we cannot eat cottonseed oil just pressed unless cottonseed oil is refined. Complete cottonseed oil plant is very important. There are two ways of cottonseed oil production process : 1. cottonseed oil press→ cottonseed oil refinery,  2. cottonseed oil pre-press→ cottonseed oil extraction→cottonseed oil refinery. Normally for input capacity more than 20 tons per day, it's better with second cottonseed oil production process with better cost performance. Here we will introduce you the second one.

Cottonseed oil production process of cottonseed oil plant:

1. Cottonseed oil pre-press:
A. Flow Chart: 
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.  

2.Cottonseed oil extraction:
A. Flow chart 
Pre-pressed oil cake → Extraction →wet meal → desolventizer →Cooling → dry meal for animal feed
                                                  Mixed oil →filter → evaporation →Crude oil
B. Points for cottonseed oil extraction plant
♦ Oil extraction is using solvent to extract oil from oil cake inside oil extractor, which has many different types: loop type oil extractor, rotocel oil extractor, towline oil    extractor etc.
♦ Oil extraction is no smoking area, all the machines especially motors are anti-explosion.
♦ Wet meal will be dried and separated with solvent inside desolventizer , the dried meal will be packaged for sale. 
♦  Mixed oil is separated with solvent by multi-effective evaporation, which has normal evapoaration and negative pressure evaporation , negative pressure evaporation is saving more energy.
♦  We offer deep processing technology of degossypolized cottonseed protein, please contact us for more information.

3.Cottonseed oil Refinery :
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.
