How much oil is extracted from 1ton of sunflower seeds?

The oil content of sunflower seeds is about 40%-50%, and the residual oil rate of sunflower oil extracted by pressing method is about 6-8%, so oil extracted from 1 ton of sunflower seeds is 320-440 kg. What factors affect the oil yield of sunflower seeds? Is there any way to increase the yield of sunflower oil when pressing it? In this regard, Henan Glory introduces the amount of oil extracted from sunflower seed oil is affected by many aspects such as sunflower seed variety, sunflower seed impurity content, extraction method and oil press performance and so on.

1. Sunflower seed varieties

Sunflower seeds are widely cultivated in the world, and there are many varieties cultivated. Different varieties of sunflower seeds have different fat content and oil content, so the difference of sunflower seed varieties will directly affect the actual oil output of sunflower seed oil extraction from the source.

2. Sunflower seeds contain impurities

The amount of impurities in sunflower seed material will also directly affect the actual oil output during sunflower seed oil processing. During the process of harvesting, transportation and storage, sunflower seeds will contain some impurities, such as sediment, stones, metal substances, etc. These impurities mixed in sunflower seeds will affect the operation of the equipment, thus affecting the oil efficiency and actual oil output of sunflower seeds. Large cooking oil processing plants are generally equipped with pretreatment equipment to remove these impurities, while small oil mills do not have the ability to purchase a whole sunflower oil processing line, often not carefully cleaned, but choose direct pressing, and the oil yield will be reduced accordingly.

3. Extraction method and oil press performance

Physical direct pressing method refers to the use of sunflower oil press equipment for mechanical pressing. If your daily processing capacity is less than 10 tons a day, you may only need a sunflower oil press machine. The final residual oil rate is around 6%, the oil content of sunflower seeds is 50%, then the oil yield is 44%. Through this calculation method, it can be calculated that oil extracted from 1 ton of sunflower seeds is 440 kg. If your daily processing capacity is more than 30 tons a day, Henan Glory Company suggests you purchase the complete set of sunflower oil pressing equipment, including sunflower seeds pretratment equipment and sunflower oil pressing equipment. If so, the final residual oil rate is less 6%. If the pre-pressing solvent extraction method is used, it generally means that the production scale of the sunflower oil production workshop is relatively large. Through the process of solvent extraction workshop, the residual oil rate in meal is less than 1%, if the oil content is 50%, the oil yield is 49%, oil extracted from 1 ton of sunflower seeds is 490 kg.

The above is the oil extracted from 1 ton of sunflower seeds and the factors affecting the oil yield of sunflower seeds. In addition to adequate pretreatment of raw materials, selection of appropriate extraction method and processing equipment, and other factors will also affect the oil yield of sunflower oil.
