Patent 10034575 was granted and assigned to Prince Castle on July, 2018 by the United States Patent and Trademark Office.
A point-of-use food holding cabinet keeps food products hot and cold in different compartments, which are heated and refrigerated respectively. Solid state heat pumps such as Peltier devices absorb heat on one side and emit heat on the other. By configuring the solid state heat sinks appropriately, one compartment or shelf of a holding cabinet can be refrigerated while an adjacent compartment can be kept warm.
