In the competitive edible oil industry, the choice of extraction method directly impacts product quality, market appeal and profitability. As a leading manufacturer of oil processing equipment, we help producers make informed decisions by understanding the the difference between pressing and solvent extraction of sunflower oil. Learn how the right technology can unlock premium oil production and meet evolving consumer demands. There are some differences between pressing and solvent extraction of sunflower oil.

1. Different processing technology:

Pressing method is the first choice of most people. Pressing method also named mechanical pressing. According to the customer's choose, there are kinds of sunflower oil pressing equipment can be used. Pressing is using mechanical pressing to get sunflower oil out, while solvent extraction is using N-hexane to extract the crude oil out, which belongs to chemical method. Large-scale edible oil solvent extraction method is another method for extracting sunflower oil, which have some impact on the environment, so environmental protection issues need to be considered. Therefore, when using the edible oil solvent extraction method, it is necessary to choose environmentally friendly and safe chemical solvents, strictly control the amount used and emissions, and reduce the impact on the environment.

2. Residual Oil Rate:

Pressing: This method typically results in a higher residual oil rate, generally about 6%-7%.

Solvent extraction: This method can achieve less than 1% residual oil content, making it the preferred method for maximizing sunflower oil extraction efficiency.

3. Oil Quality:

Pressing: Produces a more natural sunflower oilwith better flavor and fewer chemical residues. This method is often favored for premium products.

Solvent extraction: While it yields more sunflower oil, it may result in sunflower oil with trace solvents and lower sensory qualities. Additional refining steps are usually necessary.

4. Cost Considerations:

This is probably one of the most important difference between pressing and solvent extraction of sunflower oil for customers.

Pressing: Generally involves lower initial investment and operational costs, making it suitable for small to medium-scale operations.

Solvent extraction: Requires a higher initial investment in sunflower oil extraction equipment and ongoing solvent costs, making it more viable for large-scale operations where high volume is necessary. In this regard, the sunflower oil extraction machine engineer of Henan Glory Company recommends that you can choose the solvent extraction method for extracting sunflower oil when your production capacity is above 30tpd. In other words, if your production capacity is small, it is not cost-effective to buy sunflower oil extraction equipment.

In conclusion, understanding difference between pressing and solvent extraction of sunflower oil is essential for making an informed decision in sunflower oil extraction. By considering factors such as oil yield, quality, cost and environmental impact, etc, clients can choose the right extraction method that aligns best with their sunflower oil extraction goals.
