Refrigerated point-of-use holding cabinet with downloadable software

摘要

A refrigerated point-of-use food holding cabinet keeps food products cold in compartments having cross sections that are substantially U-shaped. Food products are kept refrigerated using heat-absorbing, heat-exchangers thermally coupled to the U-shaped compartment. Refrigeration is provided by either a conventional reversed-Brayton cycle, one or more Peltier devices or a chilled, re-circulating liquid that does not change phase as it circulates but which is chilled by another refrigeration system, such as a conventional refrigeration system. An optional cover helps prevent food flavor transfers between compartments. Semiconductor temperature sensors and a computer effectuate temperature control.
