Abstract

A baking oven comprises a charging section with an inlet for dough pieces to be loaded; a baking chamber; and a discharging section with an outlet for baked dough pieces to be unloaded. Provision is made for a circulating-air arrangement with a source that generates a flow of circulating air, a circulating-air heating device, and a circulating-air guiding channel, sections of which are formed by the baking chamber. An outer wall of the baking chamber is rotationally symmetrical about a vertical axis of rotation, expanding steadily upwards in particular in the shape of a funnel. A baking oven results, in which the dough pieces can be moved and distributed as regularly as possible during baking.
