Different types of screw oil press work on the same principle
Screw oil press is a commonly used oil press equipment. Its advantages are that it can deal with a variety of common oils, fast production efficiency, high oil yield, and contribute to the production of oil plants. There are many screw oil presses, and different types of screw oil presses have similar structural forms and the same working principle.
There are many types of screw oil press, and different types of screw oil press have similar structural forms and the same working principle. From the structural form, the screw oil press is generally composed of transmission mechanism, feeding mechanism, pressing mechanism, adjusting cake mechanism and so on. The press is composed of the press and screw shaft.
From the point of view of working principle, the oil is constantly moving forward with the spiral axis due to the propulsive force within the rotating spiral axis. Due to the continuous rotation of the spiral shaft, the pitch shortens, the diameter of the root circle gradually increases, the diameter of the extrusion chamber decreases correspondingly, the volume of the extrusion chamber decreases continuously, and the oil is squeezed.
In this process, due to the strong extrusion action, the oil flows out of the cage gap, the oil is squeezed into the cake, and with the rotation of the spiral axis, the cake oil can basically be separated. The disadvantage of the screw oil press is that the residual oil rate is high. The relevant practitioners are also constantly improving the existing equipment and trying to solve this problem.
The manufacturers of grain and oil machinery constantly introduce new technologies and develop new hydraulic machinery. Some oil plants adopt parallel and different double helix structure to overcome the shortcomings of single helix structure pressure system such as feed and weak thrust. The application of twin screw system can improve the axial thrust and conveying capacity, which has the advantages of high pressure, high oil rate and low residual oil rate.
