How to improve the oil yield of sunflower seeds?

Generally, the oil content of sunflower seeds is about 38%～45%, and the oil residual rate of pressing method is about 6%~7%. So the oil yield of sunflower seeds is about 31%~39%, using pressing method. If you want to improve the oil yield of sunflower seeds, there are some methods from the following aspects.

1.‌ Adopt pre-pressing leaching technology

Adopting pre-pressing leaching technology can effectively improve the oil yield of sunflower seeds, and the residual oil rate of the cake after leaching can reach less than 1%.

Sunflower seeds are pre-pressed first, about 80% of the oil is extracted, and then the sunflower seeds cake is broken and then leached in solvent extraction plant. Among them, the pre-treatment process directly affects the efficiency of oil extraction. Proper cleaning, drying and crushing can effectively destroy the cell structure of sunflower seeds and release more oil.

2. Use advanced oil pressing technology

Using screw pressing, hydraulic pressing or other advanced oil pressing technology, can be adjusted according to the characteristics of sunflower seeds and oil content, improve the oil yield.

3. Regularly maintain and upgrade the equipment

Choose the sunflower seeds oil press with stable performance and advanced technology, and regularly maintain and upgrade the oil press equipment to ensure that the oil press is in the best working condition.

4. Improve the quality of raw materials

It should be chosen the appropriate planting and management methods, the quality of raw materials also greatly affects the oil yield of sunflower seeds.

5. Rationally use the recovery system in the refining process

In the sunflower oil refining process, some oil and gas and light components will be produced, through a reasonable recovery system, can recover the oil in these substances, and further improve the oil yield.

Except for the above methods, you can also optimize site management, improve operation level, strengthen staff training, and ensure that each production link is in the best state, which can effectively improve the oil yield of sunflower seeds, and the quality and yield of oil can be guaranteed.
