US Patent 8931293 Food serving bar

A temperature controlled food serving having at least one channel of thermally conductive material for receiving at least one food-holding pan. The at least one channel defines an elongate pan receiving cavity for placement of the at least one food-holding pan at any desired location along the cavity. A temperature control system comprises at least one heating element for heating the at least one channel to maintain food products held in the food-holding pans at a food holding temperature. The at least one channel has at least two different temperature zones along a length of the channel so that food products in different temperature zones can be held at different food holding temperatures.
