Patent ID: 8468841

Claim:
A portable system for cooling perishable items, comprising: a housing adapted to rest on a surface that comprises: first and second horizontal surfaces for supporting perishable items, the first and second horizontal surfaces open at the front and sides thereof to provide free access to the perishable items from the front and sides, wherein each horizontal surface is laterally separated from the other horizontal surface, and defines flow passages at an end thereof; a vertical structure positioned between and extending upwardly from the horizontal surfaces that defines an internal vertical passage, a first set of horizontal passages extending from the internal vertical passage in a first direction toward the first horizontal surface, and a second set of horizontal passages extending from the internal vertical passage in a second direction toward the second horizontal surface; and a plurality of spaced apart supports coupled to and extending downwardly from the horizontal surfaces for supporting the housing on the surface, wherein the supports define a flow passage therebetween; a first air circulation path comprising the flow passage defined in the end of the first horizontal surface, the internal vertical passage of the vertical structure, the first set of horizontal passages extending from the internal vertical passage in a first direction toward the first horizontal surface, and the flow passage defined between the supports; a second air circulation path comprising the flow passage defined in the end of the second horizontal surface, the internal vertical passage of the vertical structure, the second set of horizontal passages extending from the internal vertical passage in a second direction toward the second horizontal surface, and the flow passage defined between the supports; a refrigeration system coupled to the housing for cooling the first and second air circulation paths; and one or more disinfectant systems coupled to the housing for disinfecting the first and second air circulation paths; and wherein each of the first and second air circulation paths comprise laminar flow portions adapted to flow over perishable items positioned on the first and second horizontal surfaces.
