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. |

DETAILED DESCRIPTION In carrying out principles of the present invention, in accordance with a preferred embodiment thereof, a stacked, dual module commercial hot air impingement pizza cooking oven is provided in which a recirculated flow of air, heated to an appropriate food cooking temperature, is utilized to very rapidly and evenly cook the top and bottom sides of pizzas operatively supported within the oven.
The lower oven module comprises a housing having a cooking chamber therein which is accessible through a swing-down door mounted on the front side of the housing.
Suitable support legs secured to the housing support it in an elevated position relative to the floor.
Depending from the lower side of the housing, generally between the support legs, is a fan and heating section utilized to create a recirculating flow of air, heated to an appropriate food cooking temperature, through the housing.
Horizontally supported within the cooking chamber is a large area, relatively thin food support plate which is uniformly perforated to provide the plate with a relatively large "open" area.
Plenum means are vertically spaced apart from the upper and lower side surfaces of the perforated food support plate and function to convert portions of the heated recirculating air into spaced series of relatively high velocity, vertically directed heated air jets which impinge upon the opposite upper and lower side surfaces of the perforated food support plate.
The jets are caused to laterally diffuse and at least slightly overlap prior to striking their associated food support plate side surface, thereby evenly blanketing such side surface with heated impingement air.
In this manner, heat from the recirculating air is very evenly transferred to the food support plate, and to the pizzas or other food items (such as bread, pastries or the like) supported thereby, at an accelerated rate to very uniformly and rapidly cook the pizzas regardless of their positions on the food support plate, and without the necessity of moving the pizzas during the cooking process
