Abstract
A food warming device having a bin for holding food products. The bin has an air delivery port and an air intake port located at first and second end walls that are disposed at first and second opposite edges of the bottom portion. The regions above the bottom portion and along the third and fourth opposite edges between the first and second walls are substantially open whereby the food products are clearly visible to customers. The bottom portion has a heated surface for receiving food products to be warmed. An air circulating means forms a stream of circulating heated air that moves from the air delivery port over the heated surface to the air intake port. The food products are warmed by heat emanating from the heated surface and by warm air from the stream of circulating heated air. A balancing system maintains the circulating air in balance by diverting a portion of the return air to ambient atmosphere through a bleed exhaust port.
