ABSTRACT:
Various mechanisms for reducing food waste in a food waste disposer are disclosed. In each of the reduction mechanisms, structures are provided for shearing food waste as it passes through or past a rotating shredder plate of the disposer. Each of the reduction mechanism has a rotatable plate having a plurality of lugs positioned for rotation relative to an inner wall of a stationary ring. In one embodiment, the reduction mechanism includes a horizontal toothed ledge positioned above the stationary ring is used to enhance grinding the food waste. In another embodiment, the reduction mechanism includes a vertical rasping surface positioned above the stationary ring. In yet another embodiment, the reduction mechanism includes serrated edges added to the vertical leading edges of the teeth on the stationary ring.
