Abstract
A rethermalization oven for heating food is disclosed, characterized by uniform distribution of heat and air through a heating chamber. The oven includes a housing and partitions for defining an outer U-shaped air plenum, a rectangular heating chamber, and a burner chamber. The side panels of the partition contain a plurality of spaced horizontal slots and the rear panel of the partition contains a plurality of spaced openings and horizontal slots of progressively increasing thickness in the directions toward the top and bottom of the housing. A heating element is arranged in the burner chamber for heating the air arranged therein. A plurality of cup baffles are connected with the housing side wall and extend across the rear leg portions of the air plenum adjacent each of the side panel slots to direct a portion of air from the air plenum chamber into the rear portion of the heating chamber through the rear portion of the slots, with the remaining portion of the heated air being uniformly distributed throughout the heating chamber via the slots. A blower including a single inlet/double outlet scroll circulates heated air from the burner chamber under pressure into the air plenum into the heating chamber via the slots, and back to the burner chamber.
