Several pressing ways of screw oil press

The screw oil press has complete specifications and reasonable prices, suitable for different levels of consumer groups. There are several pressing methods for screw oil presses, each suited for different types of oilseeds and extraction requirements.

Here are some common ways of using a screw oil press:

1, Cold Pressing: In cold pressing, the oilseeds are pressed at low temperatures (usually below 60°C) without any preheating or cooking. This method helps to retain the natural flavors, colors, and nutritional qualities of the oil. Cold-pressed oils are typically used for culinary purposes or in cosmetic products.

2, Hot Pressing: Hot pressing involves heating the oilseeds before they are pressed in the screw oil press. The seeds are usually steamed or cooked to increase the oil yield. Hot pressing can be more efficient in terms of oil extraction, but it may degrade some heat-sensitive compounds in the oil.

3, Pre-pressing: Pre-pressing is commonly used for oilseeds with high oil content, such as soybeans and sunflower seeds. In this method, the oilseeds are first mechanically pressed at a relatively low pressure to remove a portion of the oil. The resulting cake is then subjected to further extraction using solvent to extract the remaining oil.

Screw oil press machine is advanced oil press machine, characterized by the simple design, easy to use, wide suitability and continuous operation, high production capacity and high oil output rate. Almost all oil crops can be pressed by a screw press. Including peanuts, soybeans, oil sunflower, rapeseed, sesame, walnut, cottonseed and so on.
