Firstly ,the sunflower seeds need to be processed by sunflower seeds oil pretreatment  machine for high oil yield.

Process flow chart of sunflower seeds oil pretreatment  machine :

Sunflower seeds→  cleaning →crushing →softening→flaking → oil pressing → oil filtration→ extraction plant.

Cleaning machine: It removes inorganic impurities, organic impurities and oil impurities inside soybeans.

Crushing machine: Mechanical method can broke sunflower seeds into small particles for convenience of soybean flaking process.

Softening machine: It can regulate moisture and temperature of sunflower seeds, which can increase ductility of sunflower seeds.

Flaking machine: The purpose of sunflower seeds flaking is destroy sunflower tissue, create condition for steaming and roasting, make easily oil separation in sunflower oil solvent extraction.

Pressing machine:Pressing/prepressing is to press oil from oil seeds or cakes

Then the pressed cake need to be sent to sunflower seeds cake solvent extraction plant to extract sunflower oil .

Process flow chart of sunflower seeds solvent extraction plant:

Solvent extraction system→D.T.D.C system→Condenser system→Recovery system

Functions of main parts:

Extracting:To extract the oil in the cake by solvent, the general solvent is 6# extraction solvent oil or commercial hexane.

Desolventising:To remove and recover the solvent in the meal; Dry and cool down the meal at the same time.

Evaporating and stripping: Heating the the  miscella by indirect steam, so that can vaporize the solvent and concentrate the miscella.

Solvent recycling: This process is to recover the solvent, decrease solvent consumption, keep safety production and improve product quality.

Finally,the crude oil needs to be refined to get refining sunflower seeds oil, after degumming, deacidification, decoloration, dewaxing, deodorization.

Process flow chart of sunflower oil refining machine:

Crude sunflower oil → degumming ,deacidification→ decolorization →deodorization → refined sunflower oil.

(1) Purpose :Oil refining is according to the different usage and requirements , utilizing the physical methods and chemical processes to get rid of the harmful impurities and needless substance in the crude oil , getting some standard oil . Our oil refining machine is suitable for refining various crude vegetable oil, such as sunflower seed oil, tea seed oil, groundnut oil, cottonseed oil, palm oil, rice bran oil, soybean oil, corn oil and palm oil, etc.

(2)main parts: refining pot , decolorization pot ,deodorization pot , oil pumps and other parts

(3) Advantages of sunflower oil refining machine:

a.After refining the impurity of oil must be less than 0.2% ;

b.Recycling system save power and money ;

c.Lower oil waste.
