Which oil crops is the screw press suitable for

Screw oil press (usually also known as spiral oil press) is a mechanical equipment widely used in the processing of plant oil. It is suitable for pressing various oil crops, including but not limited to the following:

Common oil crops:

• Peanuts: Peanut kernels are one of the common pressing materials in screw oil presses. Before pressing, peanut kernels usually need to be treated to a certain extent, such as soaking and frying to an appropriate degree, to maintain their softness and moisture content, thereby increasing oil yield.
• Soybeans: Soybeans are also commonly used as pressing materials in screw oil presses. Soybeans need to be stir fried before pressing, until they burst and are edible, in order to improve the pressing effect.
• Rapeseed: including various types of rapeseed, such as rapeseed, etc. Due to the different moisture content of raw materials in the north and south, it may be necessary to adjust the moisture content before pressing and stir fry the rapeseed to achieve a suitable pressing state.
• Cottonseed: Cottonseed kernels are another important pressing material that also needs to be stir fried before pressing.

Other oil crops

• Oil sunflower: Oil sunflower seeds are suitable raw materials for screw oil presses due to their high oil content.
• Nut oil crops such as walnuts, almonds, and peach kernels: These oil crops are rich in oil, which can be effectively pressed and extracted through a screw press.
• Flax seeds, safflower seeds, seabuckthorn seeds, neem seeds, rubber seeds, Sichuan pepper seeds, tomato seeds, watermelon seeds, grape seeds, evening primrose seeds, chili seeds, castor seeds, perilla seeds and other special oil crops: Although these oil crops are not common, they can still be pressed by a screw press to extract high-quality oil.

The screw oil press has the characteristics of simple operation, high oil yield, and multi-purpose use. It can adapt to the pressing needs of different oil crops by adjusting the pressing parameters and process flow. In addition, the screw press can also achieve low-temperature pressing, which helps to retain the nutrients and natural flavor in the oil, and improve the quality of the oil.

It should be noted that the pressing effect of different oil crops is influenced by various factors, such as the quality of raw materials, moisture content, frying degree, and pressing process. Therefore, when using a screw press for pressing, it is necessary to make appropriate adjustments and optimizations according to the specific situation to achieve the best pressing effect.
