How does the screw oil press press oil?
Screw oil press is mainly used for individual family processing. This product belongs to hydraulic automatic oil press, small output, but convenient.
The working principle of the screw oil press is due to the conversion of the screw shaft in the extrusion chamber to promote the rate of operation, so that the extrusion connection is pushed forward. Generally speaking, due to the increase of the middle decoration of the spiral pitch on the spiral shaft and the diameter of the root circle, as well as the decrease of the diameter of the extrusion chamber, the volume connection of the extrusion space is reduced and the blasting efficiency of the extrusion material is reduced.
After the extrusion material is tightened, the grease is extruded from the cracks of the extrusion cage, and the simultaneous extrusion material is pressed into a cake block, which is eliminated from the extrusion outcome.
The screw oil press is used for sesame seeds. Rapeseed. Peanut. Cottonseed. Pressed oil of soybean, tea seed, corn embryo and other oil crops.
Screw oil press is mainly composed of press, feed hopper, screw assembly, school cake mechanism, gear box, motor and so on. For the screw press, the press is the main working part of the equipment. It consists of a spiral shaft and a cylindrical cage and can be divided into two forms: single stage press and double stage press. Single stage press has only one horizontal press, double stage press is on the basis of single stage press plus a direct press for yi stage press. When we use a screw oil press to process oil, we mainly push forward the billet continuously through the screw oil press, and extract the gross oil under the action of dynamic pressing.
The spiral shaft of the oil press is composed of several spirals and distance rings on the shaft. Each spiral has a certain pitch and depth, and the pitch of each spiral is gradually shortened from the inlet to the outlet, and the screw depth is gradually shallower, thus gradually reducing the compressed volume of the inlet and outlet. When the blank into the compression chamber, along the compression thread into the outlet, compression thread bottom diameter gradually decreases; The compression thread pushes the material embryo into the compression chamber, the compressed material embryo and the extruded oil.
