Abstract: There is disclosed a garbage disposer which pulverizes kitchen garbage, drys it and discharges only the yield water into a sewage system. This apparatus includes a garbage pulverizing segment and a garbage drying segment, both of which are driven by a common motor. The garbage drying segment includes a screw with a helical blade and a cylindrical screen disposed around the screw. In this garbage drying segment the garbage is compressed and dried as it is pressure-fed by the screw within the screen. The water thus produced flows past the screen and is discharged from the garbage drying segment into the sewage system, while the dried garbage is collected in a bag.
