PURPOSE:To obtain the titled device which can increase heating speed and carry out heating efficiently, by setting a rotary tray which places a corn storing bag on a metallic piece having antenna parts of a specific length at both the ends. CONSTITUTION:A metallic piece 4 is attached to a supporting shaft 3 connected to a rotary driving part 2 and both the ends of the metallic part are provided with antenna parts having electric length approximately corresponding to lambda/2 fundamental wavelength of microwave. A rotary tray 6 is placed on the metallic piece and a corn storing bag 8 is laid on the tray. A magnetron device 10 is fixed to the upper part of the side wall of a heating tank 1 and the inside of the heating tank 1 is irradiated with microwave from a microwave output terminal 11. |
