Abstract
A roasting oven includes an enclosure coupled to a source of microwave RF energy, an operable door for sealing the enclosure for RF, the operable door having a viewing aperture which prevents the escape of RF from inside the chamber. A rotating support has an axis which is perpendicular to the viewing aperture such that the progress of roasting may be viewed through the viewing aperture and into a food container placed in the rotating support. The applied power of the microwave RF source and the rotational velocity of the rotating support are selected to provide uniform or wide spectrum roasting of the food item. A roasting profile may include a roasting interval during which the microwave RF source and rotating support are both energized, and subsequently a cool-down interval where the microwave RF source is disabled and the rotating support continues to rotate.
