Sunflower Oil Making Machine Supplier and Manufacturer

Two Main Methods for Making Sunflower Oil

Sunflower oil production mainly involves two methods: physical pressing and solvent extraction. Each method has distinct principles and applications.
Physical Pressing Method
The physical pressing method uses mechanical force to squeeze oil directly from processed sunflower seed material. This method offers simple technology, requires fewer supporting equipment, adapts well to various oil varieties, and is flexible for production. The extracted sunflower oil has pure flavor, light color, and high quality. However, the cake residue retains more oil, has lower oil extraction efficiency, and higher energy consumption. 
Physical pressing divides into hot pressing and cold pressing:
Hot Pressing: Sunflower seeds go through steaming and roasting. High temperature destroys the oil cell structure, increases oil yield, and makes oil separation easier. The resulting crude oil has a darker color and requires further refining.
Hot pressing production process: Sunflower seeds → Shelling machine removes shells → Shell-kernel separation → Steaming cooker seeds → Oil press extraction → Filtration → Hot-pressed crude oil → Refining.
Cold Pressing: Sunflower seeds skip high-temperature treatment before pressing. This method better preserves natural flavor and nutritional components of sunflower oil and maintains lower oil extraction temperatures, but the oil yield is typically lower than hot pressing.


Cold pressing production process: Sunflower seeds → Shelling → Shell-kernel separation → Oil press extraction → Filtration → Cold-pressed oil → Refining.

Solvent Extraction Method

The solvent extraction method uses hexane to dissolve and extract oil from oils, based on solid-liquid extraction principles. This method achieves very high oil yields, minimal residual oil in cake meal, low processing costs, and suits large-scale industrial production.
Solvent extraction requires significant initial investment. The solvents typically include flammable, explosive, and toxic substances, and stringent high production safety standards. The crude oil contains more non-fat components and dark color, requiring refining processes before eat.
The solvent extraction process generally includes pretreatment, pre-pressing, mixed oil evaporation and stripping, and solvent recovery.
