Abstract

A baking oven comprises a feeding portion having a feeding aperture for introducing dough pieces, a baking chamber and a discharge portion having a discharge aperture for removing dough pieces. In addition, a circulating air unit is provided which comprises a circulating air source generating a circulating air flow, a circulating air heating means and a circulating air guiding channel a part of which is formed by the baking chamber. A plurality of receptacles for dough pieces are mounted in the baking chamber to be freely rotatable or pivotable around a horizontal rotation or pivot axis. The rotation or pivot axes of the receptacles are located higher than the centre of gravity of the receptacles even if the receptacles are filled with dough pieces. As a result, a baking oven is provided in which the dough pieces can be distributed as evenly as possible and moved along during the baking process.
