Single screw extrusion drier is suitably used for dehydration of wet materrial with the high moisture in the starch and fodder ndustries etc. Lts structure is a conical shell with the built-in taper screw pitch and height formed during the rotation. The dewetted material is ejected from the discharging end, the extruded water flows through the sieve pores in shell.

It is characterized by abig compression ratio, good dewetting effect, low moisture of output material and smooth operation without vibration. It is suitable for the continuous production.
