ABSTRACT:
A baking oven heated by circulation of hot-air comprising a baking compartment with a turntable at the bottom thereof adapted for receiving a multiple rack cart which carries the material to be baked and which is rotated around a vertical axis. The turntable is provided with a drive gear therebelow coupled to a chain which in turn is coupled to a pinion on a vertical shaft extending outside the baking compartment and driven by a drive motor. A chain box surrounds the chain and includes a portion extending outside the baking compartment which is air-tight to prevent escape of vapor thereat from the baking compartment. The vertical shaft extends into the air-tight portion of the chain box via a seal.
