Fecha de publicación: 17/04/2003 Fuente: WIPO "royal booby" A food waste disposer (100) having devices to reduce noise is disclosed. The disposer has a food conveying section (112), a motor section (114), and a grinding section (116). To reduce the emitted noise that may result when food waste impacts the various components of the grinding section, in one embodiment, the present invention uses sound reduction layers (160) attached to the external surfaces of the food conveying section, the motor section, and/or the central grinding section. The sound reduction layers may be made of materials that absorb, block, or dampen the emitted noise. The rotating shredder plate (134) may have a first metallic layer, a second damping layer, and a third metallic layer. The stationary shredder (130) ring may be made of a high-mass material or have a high-mass ring in connection with a stationary shredder ring. These devices may be combined with various disposer inlet baffles.
