PROBLEM TO BE SOLVED: To provide a microwave-based heating device capable of uniformly heating an object being processed, by a method other than disposing a rotating impeller in a heating chamber.SOLUTION: A heating device 10 comprises: a rotation drum 30 disposed such that a rotation shaft 34b is tilted diagonally upward so that an opening part 32 of an interior space in a closed-end cylinder shape housing an object being processed is located diagonally upward and a lid part 20 having a microwave emission unit 22 to emit microwaves from the opening part 32 to the interior space, the lid part covering the opening part 32 when the microwaves are emitted. The rotation drum 30 comprises: an inner circumferential surface 33 defining the internal space a bottom surface 34 closing an end part of the inner circumferential surface 33 located opposite the opening part 32 a projecting part 36 located at the center of the bottom surface 34 and projecting toward the opening part 32 from the bottom surface 34 and a plurality of blades disposed in the circumferential direction of the inner circumferential surface 33 and extending from the inner circumferential surface 33 toward the projecting part 36, the plurality of blades guiding the object being processed to the projecting part 36.SELECTED DRAWING: Figure 3COPYRIGHT: (C)2019,JPO&INPIT【課題】加熱室内に回転する攪拌羽根を設ける以外の方法で、被処理物をムラなく加熱できるマイクロ波を用いた加熱装置を提供する。【解決手段】本発明の加熱装置10は、被処理物を収容する有底円筒状の内部空間の開口部32が斜め上方に位置するように、回転軸34bが斜め上方に傾くように配置された回転ドラム30と、開口部32から内部空間に向けてマイクロ波を照射するマイクロ波照射部22を有し、マイクロ波照射時に開口部32を覆う蓋部20と、を備え、回転ドラム30は、内部空間を規定する内周面33と、開口部32の反対側に位置する内周面33の端部を塞ぐ底面34と、底面34の中央に位置し、底面34側から開口部32側に突出する突出部36と、内周面33の周方向に複数設けられ、内周面33から突出部36側に延在して被処理物を突出部36に誘導する羽根と、を備えている。【選択図】図3
