To provide a microwave drying apparatus capable of quickly and uniformly heating and drying an object to be heated.SOLUTION: A microwave drying apparatus includes a belt conveyor 3 that conveys powder Pw along a predetermined path, a drying furnace 7 that is arranged so as to intersect a belt conveyor 3 on the predetermined path and heats powder Pw by microwave R, a microwave oscillator 23 that is arranged on one end side of the drying furnace 7 and performs irradiation with microwave R from one end side to the other end side of the drying furnace 7, a non-reflective termination device 21 disposed on the other end side of the drying furnace 7, and a recovery device 9 that collects the powder Pw that has passed through the drying furnace 7, and the drying furnace 7 includes a waveguide 19 configured to transmit the TE10 mode microwave R from one end side to the other end side.SELECTED DRAWING: Figure 2 【課題】被加熱物を迅速かつ均一に加熱乾燥することができるマイクロ波乾燥装置を提供する。【解決手段】粉体Ｐｗを所定経路に沿って搬送させるベルトコンベア３と、当該所定経路上においてベルトコンベア３と交差するように配設されており、粉体Ｐｗをマイクロ波Ｒによって加熱させる乾燥炉７と、乾燥炉７の一端側に配設されており、乾燥炉７の一端側から他端側へマイクロ波Ｒを照射するマイクロ波発振器２３と、乾燥炉７の他端側に配設される無反射終端器２１と、乾燥炉７を通過した粉体Ｐｗを回収する回収器９と、を備え、乾燥炉７は、ＴＥ１０モードのマイクロ波Ｒを一端側から他端側へ伝送するように構成された導波管１９を備える。【選択図】図２
