The crushing press and the middle part of the machine are equipped with a feed hopper. The material to be dehydrated is fed into the hopper, and the juice squeezed out by the spiral flows through the screen cylinder into the juice collection tray, then discharged through the juice outlet pipe. The dehydrated residue cake is discharged from the outlet at the end of the screen cylinder.
The working process of this twin-screw press is as follows: the conveying screw pushes the material entering the feed hopper toward the pressing screw. Through the reduction of the screw pitch and the increase in shaft diameter of the pressing screw, and under the resistance of the screen wall and the conical body, the liquid content (juice) in the material is squeezed out. The squeezed liquid flows out from the screen holes and collects in the juice collection hopper. The pressed residue is discharged from between the end of the screen cylinder and the conical body. The rear part of the conical body is equipped with a spring. By adjusting the preload force and position of the spring, the discharge resistance and the size of the residue outlet can be changed to adjust the dryness of the pressed material. The 5, 10, and 20-ton/hour presses are equipped with twin screws rotating in opposite directions, providing large and uniform pressing force on the material. The residue outlet conical body is controlled by a hydraulic cylinder. Adjusting the oil pressure can change the pressing effect on the material and adjust the juice yield. This machine can also be used for solid-liquid separation of other materials, with varying effects depending on the material quality. The feed hopper, screen cylinder, and screw of this machine are made of acid and alkali-resistant 304 stainless steel.

★Product Description:
1. Juice extraction from various pomace, sea buckthorn berries, crushed ginger, bamboo shoots, and other fruits and vegetables;
2. Dehydration of fermented rice bran distillers' grains, fermented cassava residue; dehydration of Gynostemma pentaphyllum, stevia, cabbage, sedge grass, celery, residue, chrysanthemum, etc.; and dehydration of wood, wheat straw, rice straw, reed, etc.;
3. Pressing and dehydration of garbage from vegetable markets, domestic waste, and other environmental protection industries;
★Equipment Composition:
This equipment mainly consists of a frame, feeding part, pressing part, transmission part, and electrical control part. The twin screws include a conveying screw and a pressing screw rotating in opposite directions; the single-screw press, in addition to having a powerful feeding device and a non-return device, has its screw divided into three parts: the feeding screw, pressing screw, and extrusion screw.

★Equipment Advantages:
It features high strength, high load-bearing capacity, no deformation, resistance to clogging, corrosion resistance, wear resistance, no slippage, easy maintenance, and long service life. This equipment can be used as a single unit or in multiple units connected in series for better results. The residue outlet can adjust the pressing effect on the material by adjusting the spring pressure or oil pressure, thereby adjusting the dryness of the discharged residue. The pressing effect may vary depending on the material.
Compared to horizontal screw centrifuges, plate and frame filter presses, and vacuum suction filters, this equipment offers high cost-effectiveness and excellent results. It is widely used in the fruit wine and juice industry for juice extraction, as well as in other industries such as brewing, chemical, biological, and environmental protection for solid-liquid separation. The moisture content of the material after dehydration by this machine is about 60% (varies depending on the material).
