An oven includes upper and lower assemblies, a fire box and a heat absorbing and emanating device. The upper assembly forms a cooking chamber and has a front side with an open entry to the cooking chamber. The lower assembly is located below the upper assembly and has an internal cavity. The fire box is located within the internal cavity and includes a heat source. The device is located between the upper and lower assemblies and absorbs heat from the heat source and emanates heat into the cooking chamber of the upper assembly. The upper assembly includes inner and outer dome assemblies. The inner dome is located within the outer dome and forms first and second airflow pathways.

A once-through baking oven has a plurality of oven modules which together form a once-through baking space. A heat-exchange heating device for indirect heating of the once-through baking space has a heating medium outward-flow pipe arrangement, a heating medium return-flow pipe arrangement and at least one intermediate radiator pipe arrangement having a plurality of heat exchanger pipes The heating medium flows in two adjacent heat exchanger pipes in opposite flow directions to each other. In an alternative embodiment of the radiator pipe arrangement, it runs in a spiral or meander shape in such a way that the heating medium flows in two adjacent pipe sections in opposite flow directions to each other. This results in a once-through baking oven that can be operated efficiently and adapted to different throughput requirements.

An outdoor cooking appliance in combination with an air frying apparatus that has a frying burner, a blower, a heat exchanger, and a cooking chamber. The frying burner is adapted to combust fuel to create heat and other products of combustion. The blower is adapted to circulate a cooking airstream. The heat exchanger is adapted to allow passage of the heat from the combusted fuel while preventing passage of the other products of combustion into the cooking air stream. The blower is further adapted to supply the heated cooking airstream through the heat exchanger to the cooking chamber to cook foodstuff disposed therein while the other products of combustion are not supplied to the cooking chamber.

A conveyor baking oven for continuous baking operation has at least two conveyor baking spaces. A plurality of oven modules of the baking oven have baking spaces, which combine to form the conveyor baking spaces between a respective initial oven module arranged in a leading manner when seen in the bakery product conveying direction, and a respective final oven module, which is the last in row when seen in the bakery product conveying direction. The oven modules have a multi-level arrangement such as to define the at least two conveyor baking spaces. A bakery product conveyor device is used to continuously convey bakery products through the conveyor baking spaces. A thermal oil heating device having at least one thermal oil heat exchanger is used to heat the conveyor baking spaces by radiant heat. The resulting conveyor baking oven is operable efficiently and adaptable to various throughput requirements.
