The double-screw press is used for solid-liquid separation of macroscopic materials containing a certain amount of fiber or viscosity, such as fermented grape skin residue, ginger, spinach, rubber, Chinese herbal medicine, winter dates, fresh pears, apples and other fruits for squeezing juice.
Working Principle and Structure of Double Screw Press
The working process of this double screw press is that the conveying screw pushes the material entering the material box to the pressing screw. The pitch of the pressing screw decreases and the shaft diameter increases. Under the action of the resistance of the screen wall and the cone, the liquid contained in the material is squeezed out. The squeezed liquid flows out from the screen hole and is concentrated in the juice receiving hopper. The pressed pomace passes between the end of the screen cylinder and the cone. A spring is installed at the rear of the outer conical body of the discharge machine. By adjusting the pre-tightening force and position of the spring, the discharge resistance and the size of the slag outlet can be changed to adjust the dryness and wetness of the press. The press is a double screw with opposite rotation directions. The squeezing force of the material is large and uniform. The cone of the slag outlet is controlled by a hydraulic cylinder. Adjusting the oil pressure can change the pressure on the material and adjust the juice yield. This machine can also be used for solid-liquid separation of other materials. The effect varies depending on the quality of the material. difference. The feed box, screen drum and spiral of this machine are all made of high-quality acid and alkali-resistant stainless steel materials.
