Abstract: A method and apparatus for cooking food products such as flat sheets of dough is described. The apparatus includes a plurality of mating pocketed cooking irons mounted upon endless conveyors, electric or gas burners for heating the irons and a drive motor for the conveyor. Each mating pair of irons includes an upper iron provided with upwardly extending, downwardly opening recesses or pockets to engage the top of the food product being cooked and a lower iron with downwardly extending pockets. The food products expand into these pockets to form, in many cases, hollow blisters therein as the food product expands. Briefly, the method employed is to place a sheet of dough between the hot irons, close the irons by bringing their edges into contact and heat the dough therein until it expands into the pockets and is cooked sufficiently to set the crumb structure. The cooked or baked dough pieces, which can be used as pizza shells, are then topped, frozen and packaged for shipment.

Abstract: A frying apparatus for food products is described which includes a fat holding tank, a transfer conveyor within the tank extending from one end to the other for transporting food products through the tank and a drive motor for the conveyor. The conveyor is preferably provided with upwardly extending, downwardly opening recesses to engage the top of the food products within the fat. The food products extend up into these recesses so that the engagement of the food products with the recesses is adapted to prevent slippage between the food and the conveyor. The invention also includes a provision for elevating and advancing incoming products within the fat to thereby transport them toward the outlet until securely engaged by the conveyor.

Abstract: A delamination resistant fried dough product such as a pizza shell having a unique structure is described. It is composed of a flat at least partially fried body of soft porous dough and crispable outer crust with a plurality of blisters having generally hemispherical upwardly extending domed upper surfaces. The blisters usually contain one or more cavities substantially larger in size than the pores of the dough. The blisters are spaced apart from one another laterally and ligaments of dough are located between the blisters to connect the upper and lower surfaces of the crust for the purpose of unifying the crust and preventing the top portion of the crust from becoming delaminated from the lower portion during the frying process. After the crust has cooled, a topping, such as a pizza topping, sugar or glaze, fruit, cheese, egg, custard, etc. is applied to the top surface of the crust which is then usually frozen.
