The present invention provides a pre-treatment device of a screw press. The pre-treatment device is arranged before throwing material into the screw press to dehydrate preparatively. The material (S) supplied from a supply opening (15) is smoothed by axial diffusion from a diffusion plate (16) to a rolling drum, and is transported onto surface of the drum (12). Moisture of the material (S) is dehydrated with multiple dehydration holes (11) arranged on the drum (12) dependent on self weight at same time of dropping into the drum (12), simultaneously the material (S), at same time of dehydrating, is thrown into the opening of the screw press through material supply openings (17) in turn by rotation of the drum (12). Further the moisture dehydrated from the material (S) is discharged from water discharge openings (20). |
