Sunflower oil is golden with refreshing texture. It contains vitamin A, B, D and E, and rich in unsaturated fatty acids. The basic processes are: pretreatment--pre press--extracting -- refining.
The pretreatment process:
 
Sunflower seed—cleaning—shelling-- shell and kernel separation—flaking—cooking-- pre pressing—crude oil--cake

 Extracting process:
                                           solvent                solvent recovery
                                                 ↓                               ↓
Sunflower seed cake→ extractor→ mixed oil treatment→ crude oil
                                                 ↓
Recovery of solvent← evaporation of wet meal → finished meal

Refining process:
 
Sunflower seed crude oil→phosphoric acid degumming→washing and drying→dewaxing→decoloring→ physical deacidification and deodorization→dewaxing→ refined oil

When the sunflower seeds are filtered through the vibrating screen and wind sorting box, they would be sent into the sheller to separate the shell and kernel. After softening, the moisture should be adjusted to 8-9% for flaking. After steaming and frying, sunflower seeds would be sent into the pre pressing process. The oil produced through pre pressing would be refined after filtering and pre pressing cakes are into the extractor to get the sunflower seed meal and crude oil. Then, the crude oil would be sent into refining equipment.
