Screw Dehydrator

The GCP series screw dehydrator is a national patented equipment that utilizes physical extrusion for dehydration and solid-liquid separation (patent number: ZL 2020 2 1195053.0). The equipment has the characteristics of high strength, high load-bearing pressure, non-clogging, corrosion and wear resistance, convenient maintenance, long service life, etc., successfully solving the problem of dehydration of high capacity and viscosity materials.

Overview

The screw dehydrator is composed of the feeding hopper, extrusion screw, extrusion chamber, water collection tank, drainage outlet, slag discharge outlet, and driving device. By extruding to remove moisture and reduce the volume of waste, it can be used for dehydration of food waste, fruit and vegetable waste, traditional Chinese medicine extracts, pulp, organic matter, and biogas slurry residue.

Its working principle is that the material entering through the feeding hopper is pushed forward through the screen by the screw. By reducing the pitch or the depth of the screw, the volume of the material gradually decreases in the screen. Under the extrusion of the screw and screen, the extruded liquid is collected into the water collection tank through the filter screen of the extrusion chamber, and then discharged through the drainage port. The extruded material is discharged through the slag discharge port.
