Large cottonseed oil production line:
Cottonseed oil pre-pressing line→ cottonseed oil cake extraction line→cottonseed crude oil refinery line→cottonseed refined oil dewaxing line
1. Cottonseed oil pre-press line：
A. Flow Chart:
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 line:
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 line:
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
4.Cottonseed oil dewaxing line:
Dewaxing is optional depending on your requirement.
The new technical of fractionation invented by our company adopt full automatic control,our product has high advance technical ,stable quality.
Compare with the traditional dewaxing technical of adding filter aid,the new one has characters as follows:
(1)Don’t need to add any filter aid agent, the products are natural and green
(2)Easy to filter,the product oil has high yield
(3)Pure by-product edible wax,not contain filter aid agent and can use the edible wax production directly,no pollution
(4)High automaticity and can suit to large-scale commercial run
