Abstract
An improved oven is aimed at optimizing heat transfer and delivering an optimal cooking efficiency in comparison to conventional high-speed cooking ovens. The oven includes a support for supporting a food product in a cooking chamber of the oven, which utilizes impingement of hot air and microwave energy. The support includes a metal plate having a surface for receiving a food product thereon and at least one aperture located at an outer periphery of the metal plate adjacent the surface. The aperture permits heated air to flow therethrough as the heated air flows in a return path from the cooking chamber. The aperture also limits the reflection of microwave energy within the cooking chamber.
Claims27
An oven for cooking a food product, comprising:
- a cooking chamber comprising a top, a bottom, a side wall, and a cooking plate receiving a food product, the food product having a cooking surface;
- a conduit in fluid communication with the cooking chamber;
- one or more blowers communicating a gas flowing through the conduit to the cooking chamber;
- a thermal energy source heating the gas;
- a tube or a nozzle generating an airflow of the heated gas from the conduit and introducing it into the cooking chamber;
- wherein the cooking plate promotes movement of the airflow along the cooking surface toward the side wall of the cooking chamber,
- wherein the airflow flows toward a return air opening,
- wherein the cooking plate includes at least one aperture located near the return air opening so that the airflow reaches the return air opening through the cooking plate.
An oven for cooking a food product, comprising:
- a cooking chamber comprising a top, a bottom, and a side wall;
- a conduit and one or more blowers for providing a gas into the cooking chamber;
- a thermal energy source for heating the gas disposed in the conduit;
- a tube for generating a plume array of the heated gas from the conduit and introducing it into the cooking chamber;
- and
- a metal cooking plate disposed in the cooking chamber for receiving the food product, wherein the metal cooking plate absorbs heat from the plume array of heated gas and transfers the heat to the food product.
