What is a Screw Oil Press?
Screw oil press, also known as an oil expeller, is a machine that uses a screw to press oil seeds and extract the oil. The screw rotates at a high speed, pushing the oilseeds through the barrel and crushing them to release the oil. The oil is then expelled through the small openings on the barrel walls and collected in a container.
Screw oil presses are one of the most common types of oil presses used for the extraction of vegetable oils. They are widely used in both small-scale and large-scale oil production processes due to their versatility, high oil yield, and ease of operation. Screw oil press has the features of high yield, strong adaptability and continuous operation, etc. It is widely used for crushing various kinds of vegetable seeds, such as peanut, rapeseed, soybean, sunflower seed, cottonseed, palm seeds, etc.
Small Screw Oil Press
Small oil press is mainly used in small and medium oil mill. It has the advantages of simple structure, convenient operation and high production. High carbon steel and heat treatment improve the service life of small oil press and make it suitable for continuous operation of high temperature and high pressure. The small oil press can be used for decades.

Automatic combined oil press with vacuum filter
Fully automatic oil press is the latest oil equipment developed on the basis of screw oil press. The vacuum filter oil press is equipped with automatic temperature control system and vacuum filtering system, which not only improves the oil yield, but solves the problem of oil purification with more simple operation and higher production efficiency.

Large Screw Oil Press
Large screw oil press, also called pre-press machine, is suitable for pre pressing or twice pressing process in large oil plant. It can be used alone as the oil press or as the pre-press machine of oil plant. According to the market demand, we developed a new generation of cold pressed oil machine, specifically designed for cold pressed oil plants. The cold pressed oil machine is suitable for crushing organic plants and high value-added crops. In the pressing process, the oil temperature is lower with high oil yield and low residual oil. Oil produced by the cold pressed oil machine has relatively shallow color, good quality and rich nutrition and able to reach the standard of oil in the international market.
