Abstract
A food waste disposal apparatus having an improved effluent recirculating structure for facilitating dislodging of waste material which may become lodged in the comminuting portion of the disposer. The recirculating structure includes a tubular wall member having a plurality of openings to the grinding chamber above the cutter-impeller structure. The tubular wall member is spaced inwardly of the housing to define therebetween an annular flow space for conducting a portion of the effluent delivered from the cutter-impeller outwardly to and inwardly through the wall member openings to provide the desired waste dislodging recirculation of the effluent.
