  Screw dehydrators can be widely used for the dehydration process of high-moisture materials, such as vinasse, wood powder, pomace, medical residue, cassava dregs, beer spent grain, food waste,etc. This kind of dehydrator could take off 20% to 25% moisture of the wet materials, lower the energy cost and reduce the duty of BSG dryers, which can significantly increase the output. The output can be directly delivered into the dry equipment, greatly lower the energy consumption for the following process. 


  The screw dehydrator is a new type of high efficiency continuous operation solid-liquid separation equipment, Compared with the traditional centrifugal filtration, vacuum filtration, filter press dewatering method, This kind of screw dehydrator has the advantages of large processing capacity, low energy consumption, small occupation area, low labor intensity, simple operation, convenient maintenance, less wearing parts, etc. It can be used in a single machine, and can also be used in series and parallel connection with multiple machines, According to material corrosion and customer requirements, the machine can be made of carbon steel or stainless steel.

Product Working Principle

  The screw dehydrator is consist of feeding box, conical screw, water filter, filter cage, frame, adjustable-speed motor, rate reducer, gearbox and other parts. It has the characterization of high strength, high bearing pressure, non-deformation, non-jam, corrosion resistance, wear resistance, non-skid, easy maintenance and long service life. At working state, wet materials are dropped into feeding box at steady rate and then pushed to discharge end by screw rotor blades dewatering. Under the strong extrusion force of screw and dumper regulator, wet materials complete the process of mechanical dehydration. Moisture is taken away when going through the screening mesh and exhausted at the gas discharge outlet. The dry materials are collected at product discharge outlet. For the best balance of drying effect and output, it is applicable for customers to change the operation parameters according to the property of materials and  required output.
