Abstract
An oven comprises a housing and at least one heater and a conveyor belt which runs through the housing and on which food products to be heated can be accommodated. The belt runs in two helical paths about spaced parallel vertical axes, the direction of movement of the belt along one helical path, as seen from above, being opposite the direction of movement of the belt about the other helical path. The housing comprises two chambers separated by a partition, one of the helical paths of the conveyor being disposed in one chamber and the other helical path being disposed in the other chamber. The partition has an opening through which the belt runs between the chambers. In this way, different temperature levels can be maintained in the two chambers.
