Waterless dishwasher

Abstract

A dishwashing system for cleaning soiled kitchenware, dishware and utensils is provided. The dishwashing system uses a combination of compressed air and blasting media to thoroughly remove grease and loose as well as hardened food particles from soiled surfaces, without hand tool scrubbing, manual rinsing, or use of soap, detergent, surfactants or other chemicals, whether in pre-soaking or cleaning. This heavy-duty dishwashing system accomplishes this thorough cleaning using no or a minuscule quantity of water. The overall energy requirements are low compared to existing systems due to elimination of water, reduction of the heating load and possible use of the heat of incineration. The dishwashing system may include a system for reclaiming used blasting media by separation from food residues. The dishwashing system is most appropriate for locations where freshwater is unavailable or costly, such as arid zones and aboard ships, and where disposal of gray water is impermissible.
