A food preparation oven comprising a plurality of radiant panel ducts which include apertures for directing streams of heated air toward a food product within the heating chamber. The radiant panels are made of highly thermal conductive aluminum and the outer surfaces thereof facing the food product are of a black color so as to radiate infrared energy toward the food product.

Oven with radiant panel

A food preparation apparatus including a cooking chamber having a pair of openings in two opposite facing walls thereof. A conveyor extends through the side wall openings in the chamber for conveying a food product through the chamber. First and second pairs of impingement finger ducts are provided for forming a plurality of columnated air jets and for impinging the jets against discreet points of a food product supported on the conveyor. A first one of each of said pairs of finger ducts is disposed above the conveyor and a second one of each of said pairs of finger ducts is disposed below the conveyor. First and second plenums, each of which has a fan respectively associated therewith, supply air to the finger ducts. A single burner is associated with the plenums for simultaneously supplying thermal energy to both plenums. The burner includes a first adjustable baffle for apportioning the thermal energy between the two plenums. The burner includes a second baffle located in the return air stream forwardly of the burner flame to generate a negative pressure zone and draw the flame forwardly, away from the back wall of the burner.

Burner for low profile inpingement oven

An oven for preparing food products such as pizza including three chambers which are serially connected and through which a conveyor carries a food product which may be received in an open-topped pan or which may be placed directly on the conveyor. The center chamber includes steam impingement structure for impinging jets of hot steam onto the top surface of the food product. The center chamber also includes a hot air impingement structure for impinging jets of hot gas onto the bottom surface of the container of the food product. The first and last chambers in the oven include hot air impingement structure for impinging hot jets of air onto both the top surface of the food product and the bottom surface of the pan.

Impingement and steam oven apparatus for preparing food products

A heat duct support assembly for an impingement oven having a plurality of horizontally oriented heat ducts therein, which are connected to a plenum to direct hot air from the plenum against food being conveyed through the oven. The assembly comprises two studs projecting from each of the oven opposite sides and an elongated bracket horizontally positioned between the oven opposite sides for supporting the remote ends of the heat ducts. The bracket is supported by a pair of bracket supports connected to its ends and which are adjacent to the opposite sides of the oven. The bracket supports have slots in their bottom and top edges that engage the studs in order to support the bracket between the oven opposite sides. The opposite ends of the heat ducts are supported by flanges peripherally disposed about openings in the plenum and over which the heat ducts are fitted. The method comprises providing the studs and bracket with the bracket supports, positioning the bracket in the oven and guiding the slots in the bracket supports in alignment with the studs, and then rotating the bracket to engage the slots with the studs. Thereafter, the heat ducts are fitted over the flanges and the remote ends rested on the bracket.
