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.
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 extracted?
The seed is mechanically pressed (pre-pressed) to extract approximately half to three-quarters of the obtainable oil so that the solvent extraction can be run more efficiently. This is typical for seeds having more than 20% oil. The solvent extraction procedure uses hexane or other solvents to wash the sunflower oil from the prepared flakes.
Is expeller-pressed sunflower oil better than solvent extraction?
While the solvent extraction method has a lower residual oil rate, it might entail a significant solvent consumption, resulting in elevated production costs for sunflower oil processing plants. Consequently, many oil production plants are inclined to opt for the method of expeller-pressed sunflower oil, achieving the desired production outcomes.
