Abstract: Various representative commercial cooking devices are disclosed wherein a recirculating flow of heated air, at a food cooking temperature, is created within a housing in which a horizontally disposed food support and cooking member, such as a perforated metal plate, a solid griddle plate or a metal broiling grate, is positioned. A plenum structure is utilized to convert a portion of the continuously recirculated air into a spaced series of relatively high velocity heated air impingement jets which are caused to laterally diffuse and at least slightly overlap prior to striking at least one side surface of the food support structure. In this manner, each food support structure side surface subjected to such diffused jet impingement is evenly blanketed with heating air to thereby very uniformly transfer heat from the air to the food support structure, and thus to the food supported thereby, at an accelerated rate.

Abstract: A commerical, dual tier pizza cooking oven is formed from substantially similar but relatively inverted lower and upper modules. The lower module has a housing, with a cooking chamber therein, which is floor supported in an elevated position by suitable depending support legs and has a downwardly projecting fan and heating section used to create a recirculating flow of air, heated to a suitable food cooking temperature, through the housing. The upper module housing is stacked on top of the lower module housing, and its fan and heating section projects upwardly therefrom and also operates to create a recirculating flow of heated air through its cooking chamber. Perforated metal food support plates are horizontally disposed in each of the two cooking chambers for support the pizzas to be cooked. Plenum structures on opposite sides of the support plates in each of the two cooking chambers operate to receive portions of the heated air recirculated therethrough and convert them to series of heated air cooking jets which evenly blanket the opposite sides of the support plates in a manner transferring heat thereto at an accelerated rate to thereby rapidly and evenly cook the pizzas or other food items supported on the plates.

Abstract: Cooking oil contained in a fuel-fired deep fat frypot is heated utilizing a recirculating flow of combustion gas produced by an induced flow fuel-air burner. A squirrel cage type centrifugal fan draws a fuel-air mixture inwardly through the burner into an inlet chamber in which the combustion gas is formed. The hot combustion gas is discharged from the fan into a supply chamber, flowed from the supply chamber into and through external heating passages extending rearwardly along the opposite exterior side surfaces of the frypot, and then enters an external heating passage extending along the rear frypot wall. From this rear passage the combustion gas is drawn forwardly through generally triangularly shaped heating tubes extending horizontally through the frypot cooking zone, into and through a return plenum, into the fan where it is mixed with a fresh supply of combustion gas from the inlet chamber, and is then discharged into the supply chamber. During burner operation excess combustion gas is discharged to atmosphere through an appropriate vent stack. A motorized inlet damper is mounted on the inlet plenum and is operable to admit ambient air thereinto to rapidly lower the recirculating gas temperature to prevent oil temperature overshoot. Rigid insulation material is positioned in lower interior portions of the heating tubes to increase the gas flow velocity therethrough and to shield the lower "cold zone" of the frypot from tube heat. In an alternate embodiment of the frypot the fuel-air burner is replaced with electric heating elements operatively disposed within the supply chamber.
