1.  Crude Cotton seed oil refining plant:

Dephosphorization → dealkalizing → dewaxing → descoloring → deodorization → refined oil
Crude Cotton seed oil refining section:

•   The oil refining process is quite identical. There are two routes are taken to process crude oil into refined oil; which are chemical (basic) refining and physical refining.
•   The methods differ basically in the way the fatty acids are removed from the oil. Physical refining, which eliminates the need for an effluent plant for the soap stock, involves subjecting the oil to steam distillation under higher temperature and vacuum for removal of the free fatty acids. The physical refining is used to remove the free fatty acids.
•   The refining of physical plant is practiced to subject the oil to steam 

2.  Working Principle: 

(1)Pump crude oil into refining tank and heat with conduction oil, and the temperature will reach about 70°C -80C after one hour. Add acid or alkali to separate according to the acid value. After one hour's processing and 4-6 hours deposit, then convey soap stock to storage tank.

(2)Pump refined oil into decoloring tank. When it is up to 90-110°c after one hour's heating, add clay into tank for 20min's processing. Then separate clay and oil with filter.

(3Put discolored oil into deodorization tank with vacuum pump. Heat and process with steam for odor removal.After filtering, you will get final oil product.

Detail processing line:

►  The neutralizing tank is used for acid for acid,alkali refining or rinse
►  The decoloring tank is for bleaching grease
►  The deodorizing tank is sued for deodotization tank
►  The conducting oil furnance provide the heating for production
►  The vacuum pump provide vacumm for bleaching , deodorization which is can reach 755mmkg
►  The air compressor can dry the bleached clay
►  The air press is for filter clay
►  The stream gererator can gererate stream distillation
►   The quality of refined oil reached to the standards for edible oil and santitation by neutralization using phosphoric acid, water washing

3. Crude Cotton seed oil refining effect:

•   After refining the impurity of oil must be less than 0.2% ; 
•   Recycling system save power and money; 
•   Lower oil waste.
