This is a mechanical method (An oil press machine) used for extracting oil, suitable for both large-scale and small-scale production of sunflower oil. It can be used for the initial processing of sunflower seeds to extract oil and leave behind oil cake. Sunflower oil can be pressed using either cold-pressed or hot-pressed methods.
What are the two methods of sunflower oil extraction?
Common sunflower seed oil extraction processes can be categorized into two methods: expeller pressed sunflower oil and solvent extraction. Next, we will briefly introduce these two methods of sunflower oil production. Sunflower Oil Press & Extraction Machinery for Sale What is expeller pressed sunflower oil?
How is sunflower oil pressed?
Sunflower oil can be pressed using either cold-pressed or hot-pressed methods. Cold pressing sunflower oil involves oil extraction through physical mechanical means without heating, or at low temperatures (<40°C). This entire process occurs at a low temperature, resulting in a lower oil yield but preserving the authentic taste of the seeds.
What is a solvent extraction machine for sunflower oil?
Expeller pressed sunflower oil and solvent extraction methods are two common production processing for sunflower oil. Using the pressing method typically results in an oil residue rate of around 7%, whereas solvent extraction can reduce the oil residue rate to about 1%. It’s worth noting that solvent extraction machine is costlier.
