  • Patent number: 8455797
    Abstract: The present invention is directed to improving the conventional high-speed cooking oven based on a combination of hot air impingement and microwave heating by providing a time-dependent spatial variation in the net air impingement and/or net microwave energy applied to the food product in the oven. This is aimed at optimizing heat transfer and microwave efficiencies in a high-speed cooking oven, thereby enabling the oven to deliver an optimal cooking efficiency in comparison to the conventional high-speed cooking oven. In addition, under the embodiments of the present invention, the cooking efficiency may be further optimized by providing a plenum between each wall of the cooking chamber and the housing of the oven.

  • Publication number: 20120175090
    Abstract: An improved heating apparatus is aimed at optimizing heat transfer and delivering an optimal heating efficiency in comparison to conventional heating apparatus. The improved heating apparatus includes tubes that generate plume arrays of a fluid (e.g., a gas, such as air) that is heated in a conduit. The tubes introduce the heated fluid into a chamber of the heating apparatus. The fluid is returned to the conduit through a return opening in the chamber. The path that the fluid travels in the chamber, from the tubes to the return air opening, is provided such that optimized heat transfer and optimal heating efficiency are facilitated.

  • Publication number: 20120138045
    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.

  • Patent number: 8026463
    Abstract: The present invention is directed to improving the conventional high-speed cooking oven based on a combination of hot air impingement and microwave heating by providing a time-dependent spatial variation in the net air impingement and/or net microwave energy applied to the food product in the oven. This is aimed at optimizing heat transfer and microwave efficiencies in a high-speed cooking oven, thereby enabling the oven to deliver an optimal cooking efficiency in comparison to the conventional high-speed cooking oven. In addition, under the present invention, the cooking efficiency may be further optimized by dimensioning the nozzles for hot air impingement to tighten impingement plumes, subject to the space constraint of the oven's cooking chamber, and dimensioning the cooking chamber of the oven in integer multiples of the wavelength of the microwave energy to match the microwave load.

  • Patent number: 8022341
    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 tubes that generate plume arrays of a heated gas and introduce them into a cooking chamber of the oven. The tubes may be removably located at the bottom of the cooking chamber of the oven. The tubes are dimensioned for hot air impingement to tighten impingement plume arrays, subject to the space constraints of the oven's cooking chamber. With the optimized cooking efficiency provided by the present invention, high-speed cooking technology may now be extended to ovens operating on a power supply based on a voltage less than 220 volts, preferably between 110 and 125 volts, with more productive results, so that the high-speed cooking technology may find wider applicability and a broader customer base.
