  • High speed oven
    Patent number: 5954986
    Abstract: A heating apparatus includes a central support axle positioned within a heating chamber of the heating apparatus. The heating apparatus provides both hot-air heating and micro-wave heating. A turntable has a central portion supported by the central support axle so that the turntable is rotated around the central support axle. A driving source is positioned at an upper side of the heating chamber for generating a rotating torque, and a connecting shaft for transmitting the rotating torque generated by the driving source to the turntable is provided in the heating chamber. The turntable has an entirely flat shaped section including a plane on which food products to be heated are mounted. A central portion of the flat shaped section is defined at a concave which is downwardly recessed into the plane and arranged to be fixed to and supported by the central support axis.
