- a cooking chamber defined by an enclosure having at least one inlet and at least one outlet formed therein, said cooking chamber being divided into high pressure and low pressure regions,
- a pervious conveyor arranged in said cooking chamber providing a substantially helically extending path on which said food products will travel in said cooking chamber from said inlet to said outlet,
- means to provide a heated gaseous cooking medium within said cooking chamber,
- fan means for circulating said heated gaseous cooking medium from said high pressure region to said low pressure region in said cooking chamber, wherein said conveyor is constructed such that said gaseous cooking medium can circulate through said conveyor and around said food products positioned on the conveyor in a continuous manner for efficient heat transfer from said heated gaseous cooking medium to said food products.
- 2. An oven in accordance with claim 1, wherein,
- said means to provide said heated gaseous cooking medium into said cooking chamber comprises at least heater means for heating a gaseous cooking medium within said cooking chamber.
- 3. An oven in accordance with claim 2, wherein,

- 5. An oven in accordance with claim 2, wherein,
- said heater means comprises a remote heat exchanger which is adapted to direct heated air into said cooking chamber.
- 6. An oven in accordance with claim 2, wherein,
- said heater means comprises a thermal fluid heating means disposed within said cooking chamber adapted to heat the gaseous cooking medium within said cooking chamber.
- 7. An oven in accordance with claim 2, wherein,
- said heater means comprises an electric heating means disposed within said cooking chamber adapted to heat the gaseous cooking medium within said cooking chamber.
- 8. A cooking oven in accordance with claim 1, wherein,
- said conveyor is a self-supporting pervious belt which may be formed in superimposed tiers forming a pervious annulus.
- 9. A cooking oven in accordance with claim 8, wherein,
- said sides of said annulus formed by the superimposed tiers of said conveying means include small apertures therein which allow an amount of heated gaseous cooking medium to flow transversely to said annulus to equalize temperatures across said conveying means and within said annulus.
