Sunflower seed pretreatment: magnetic separator, cleaning sieve, stone removing machine, peeling and kernel separation equipment, embryo rolling machine, steaming and frying pan

Sunflower seed press: After pretreatment, sunflower seeds will be transported into a sunflower oil press for squeezing to obtain sunflower oil.

Sunflower seed oil solvent extraction:

1.sunflower seeds cake → Solvent Extraction → Wet meal desolventizing → Cooling → Product meal packing

2.Solvent Extraction → Miscella → Filter → Negative pressure evaporation → Crude oil Solvent

3.Negative pressure evaporation → recovery

Sunflower oil refining:

1. Degumming-using hydration degumming to remove peptic impurities;

2. Deacidification-use chemical or physical methods to remove free fatty acids;

3. Decolorization-use the adsorption of white clay to remove the pigment in the oil and improve the color of the oil;

4. Deodorization-use the difference in the volatility of oil and odor substances to remove odor substances;

5. Dewaxing-It mainly adopts freezing, crystallization or winterization crystallization to remove wax fat in oil by fractional distillation.
