Abstract: A waste disposer comprises a shredder section for shredding waste material and a water remover section coupled integrally with the shredder section for removing water from the waste material, in which the shredded waste material is carried upward throughout a cylindrical screen member mounted in the water remover section by the rotation of a screw while its containing water being removed and drained through apertures of the screen member. A plurality of vertically extending rib portions are arranged at equal intervals on the inner wall of the screen member so that screw blade comes in direct contact with the rib portions during its rotation. A plurality of pins are provided at equal intervals on the outer edge of the screw blade, each pin having a length sufficient to run directly on the inner wall of the screen member as the screw rotates.
