Types : Disposers with rotor-fixed cutting teeth are the most common varieties, although some may be equipped with swivel cutting teeth or a hammer-mill-type grinder. In all instances, a cutter rotates at a high speed inside a stationary shredder ring. As centrifugal force moves foods through a shredder, waste washes into the lower area of a unit and down a drain or into a compactor.
Waste compactors are available in a variety of styles. A new type of pulper is an organic-waste disposal system. The completely self-contained system decomposes food waste into liquid by applying heat, water and motion to organic waste held in a central drum. Disposal of the resulting liquid occurs through existing sewage treatment facilities. The liquid's nutrient-rich nature allows operators to add it asa supplement to irrigation andplant-watering systems. Such a system practically eliminates on-site food waste, reducing the risks posed by cross-contamination, pests and other health threats.
Capacities/Footprints : Disposer motors range from ½ hp up to 10 hp. Smaller horsepower units can attach to sinks with no support necessary. More powerful disposers require a leg that reaches the floor for support. Horsepower determines shredding capability, as well as their capacity for continuous operation. Light-duty disposers are intended for use in delis and convenience stores. Heavy-duty, small-, medium- and large-capacity disposers are designed to meet the needs of larger operations. The body size of a disposer determines its waste-handling capacity. Compactors are used in conjunction with disposers. Compactors are available in 1, 2, 3 and 5 hp,...
