Sunflower seeds shelling in sunflower oil production line

Sunflower seeds need to be shelled during the sunflower oil production process for several reasons

The shell of sunflower will harmful to the oil presser. The life of screw of oil presser will be reduced by the shell.There are much wax in the sunflower seed. When the shell is not moved, the wax will keep in the oil. The quality of final oil will not good as the oil from sunflower without shell. The consumption of the refinery is increased, because the quality of final oil is bad.

Oil Quality: The shells of sunflower seeds contain a high amount of fiber and other non-oil components. If the shells are not removed, they can negatively affect the quality of the oil, making it darker and more bitter. Removing the shells helps produce a clearer, lighter, and more refined sunflower oil.
Oil Yield: The shells themselves do not contain oil, so leaving them on would reduce the overall oil yield per unit of seeds processed. By removing the shells, the sunflower oil extraction process becomes more efficient, as it focuses on the part of the seed (the kernel) that contains the oil.
Processing Efficiency: Shells can interfere with the sunflower oil extraction machine. They can clog funflower oil machinery, reduce the efficiency of sunflower oil pressing, and increase wear and tear on equipment. Removing the shells beforehand helps streamline the sunflower oil extraction process.

Byproduct Utilization

The separated shells can be used for other purposes, such as animal feed, fuel, or as a raw material in other industries. This adds value to the overall sunflower oil production process and reduces waste.
Taste and Texture: The shells can impart an undesirable taste and texture to the sunflower oil. Removing them ensures that the final product has a smoother texture and a more neutral flavor, which is preferred for cooking and other uses.
In summary, shelling sunflower seeds is a crucial step in the sunflower oil production process to ensure high-quality oil, maximize oil yield, improve sunflower oil processing efficiency, and create valuable byproducts.
