Cottonseed oil solvent extraction plant is the second step in cooking oil making machine .Product (cake from cooking oil press section) is carried into solvent extraction palnt.There are still much oil in cake.Cottonseed oil solvent extraction plant is the machine to extract oil from oil cake which can ensure the residual oil rate is less than 1%.
Cottonseed oil extraction process
Main equipment of cottonseed oil solvent extraction plant: 1. Solvent oil extractor
Oil extractor is most important equipment used in rapeseed oil plant . It can be divided into batch oil extractor and continuous oil extractor. Batch oil extractor is used for small capacity sunflower oil extraction. Common used continuous oil extractor is rotocel oil extractor, loop type oil extractor, towline oil extractor etc. 2. Wet meal desolventizer
Discharged from oil extractor, wet meal contains 25-35% solvent, in order to reuse this solvent and get good quality of meal, using desolventizer to steam evaporate solvent.Desolventizer normally is high layers steam desolventizer. 3. MIxed oil evaporators
Using multi-effective evaporators to separate solvent with oil because of different boiling point. Multi-effective evaporators includes first evaporator, second evaporator and stripping tower. After first and second evaporators , most solvent is transformed into gas by high temperature steam. And then stripping mixed oil to remove residual solvent in order to get low solvent residual crude oil. 4. Solvent condensing and cooling
Solvent gas from first and second evaporator doesn't contain water, can be recycling directly after cooling by condensers. Solvent gas from stripping tower and desolventizer is mixed with steam, which need to separate with water by water distributor after condensers.
Common condenser is tube nest condenser.
For big capacity more than 100 t/d, cottonseed oil solvent extraction plant can adopt negative pressure oil extraction.

Craft features of cottonseed oil solvent extraction plant:
1,Adopting negative pressure evaporation can ensure excellent oil quality;
2,extraction system is highly adaptable,and can adapt to different oilseeds;
3,unique exhaust gas absorption systems ensure good absorption effect;
4,full energy-saving design utilize heat energy for many times and saves steam consumption.
The consumption standard of cottonseed oil solvent extraction projest:
1.1ton oilseed can consume steam less than 380g.
2. 1ton oilseed can consume electricity less than 15 kw
3.1ton oilseed can consume recycling cooling water less than 20 ton.
4.1ton oilseed can consume solvent less than 2kg
