  • Oven with automatic open/closed system mode control
    Patent number: 10119708
    Abstract: A commercial oven, such as a combination oven providing steam and convection heating, may provide for motorized dampers allowing the oven to move automatically between a closed-state high humidity operating mode and an open-state low humidity operating mode according to user input reflecting a desired cooking process. The dampers operate with a conventional steam trap and may provide integrated bypass valves preventing over or under pressure of the cooking volume.
    Type: Grant
    Filed: April 23, 2013
    Date of Patent: November 6, 2018
    Assignee: Alto-Shaam, Inc.
    Inventors: Janus Bartelick, J. K. Raghavan, Steve Maahs
  • Combination oven with peak power control
    Patent number: 9841261
    Abstract: A commercial oven, such as a combination oven providing steam and convection heating, may provide for two different peak power modes and for steam cooking. A temperature sensor sampling temperature from a region of the oven may be used to detect a complete filling of the oven with steam. The temperature of the temperature sensor is compared against different temperature thresholds depending on the selected peak power so that temperature may be used to discriminate steam filling for different peak power levels.
