How to achieve maximum oil from sunflower seeds oil processing?

In sunflower seeds oil processing process, to achieve maximum oil from sunflower seeds, you can choose high oil yield rate oil extraction process, or improve the machines in sunflower seeds oil pressing line to obtain better effect.

The different oil extraction process has different oil yield rate. Generally, the residual oil rate of pressing process is about 6-8%, and the residual oil rate of solvent extraction process is less than 1%. But the solvent extraction machines are suitable for large scale capacity. So if your daily processing capacity is more than 20 tons sunflower seeds, choosing solvent extraction process can help you to achieve maximum oil from sunflower seeds oil processing.

If you choose pressing process to processing sunflower seeds oil, there also are some methods to help you to achieve maximum oil from sunflower seeds oil processing.

1. You had better shell the sunflower seeds.

The shells of sunflower seeds will absorb some oil when pressing, so removing the shells of the sunflower seeds will decrease the residual oil rate and increase the oil yield rate.

2. Cooking machine and flaking machine are necessary

Except for the shelling machine, cooking machine and flaking machine can also help you to achieve maximum oil from sunflower seeds. Cooking is adjusting the temperature and moisture to make the the sunflower seeds to reach the best conditions for extracting oil. And flaking is making the sunflower seeds into small pieces, which will break down the inner structure of the sunflower seeds, and make it easier to extract oil.

3. You can use several small oil presser to replace a large oil presser

Oil presser will also influence the oil yield rate. The residual oil rate of big capacity oil presser is a little higher than the smaller capacity oil presser. So if it is OK, you can choose to use several small oil presser to replace a large oil presser.
