Single screw extrusion drier is suitably used for dehydration of wet material with the high moisture in the starch and fodder industries etc. machine structure is a conical shell with the built-in taper screw belt of varying screw pitch. The
compression take place due to two factors of screw pitch and height formed during rotation. The dewatered material is ejected from the discharging end, the extruded water flows through the sieve pores in shell. It is characterized by a big compression ratio, good dewatering effect, low moisture of output material and smooth operation without vibration. It is suitable for continuous production.
