Screw oil press can be divided into single screw oil press and double screw oil press. Double-screw oil press is a screw oil press with two screws running in opposite directions in the agreed press cage, which is suitable for pressing various oils. Compared with the traditional oil press, the advantages of double screw oil press are mainly reflected in the following aspects:

1. Higher squeezing efficiency: The double-screw oil press has two screw shafts, which rotate in opposite directions and the screw directions are opposite, so that the oil is squeezed and sheared more evenly in the squeezing chamber, and the oil can be squeezed out more fully, which shortens the squeezing time and improves the production efficiency.

2. Higher oil yield: The double helix structure can form a more reasonable pressure gradient in the press chamber, so that the oil can be fully squeezed out. Compared with the traditional oil press, it can improve the oil yield and increase the oil yield.

3. Good oil quality: The double-screw oil press can control the temperature well during the pressing process, especially suitable for the cold pressing process, which can avoid the oxidation and deterioration of oil caused by high temperature, retain the nutrients and flavor substances in oil and improve the quality of oil.

4. Better adaptability: By adjusting the parameters such as the rotating speed of the screw shaft, the pressure and temperature of the press chamber, the double-screw oil press can adapt to the pressing of various oils, whether it is oils with high oil content, such as peanuts and sesame seeds, or oils with low oil content, such as soybeans and cottonseed, etc., it can achieve better pressing effect.

5. High degree of automation: The equipped automatic control system can realize the automatic operation of feeding, squeezing, oil discharging and cake discharging, reducing manual intervention and labor intensity, and improving the stability and consistency of production.

Double-screw oil press is often used in the production of cold pressed oil, which can increase the oil yield and better retain the nutritional flavor of oil, and has the advantages of high oil yield, high production efficiency, good oil quality, strong adaptability and convenient maintenance.

The quality of equipment has a great influence on the oil quality and oil yield when purchasing a double-screw oil press. Therefore, for the purchase of oil press equipment, we should compare and inspect the material, technology, brand reputation, manufacturer’s strength and other aspects, and choose a reliable manufacturer to cooperate. It is recommended to consult and inspect Henan Huatai Grain and Oil Machinery Factory.
