PROCESSING UNIT

Provided is a processing device that can efficiently carry out microwave irradiation. A processing device is provided with: a vessel 101 that is constituted of a material having microwave reflectivity, has a first end part 1015a and an irradiation opening 1013 that is an outgoing part for microwaves irradiating inside; a first filter 105 that is disposed so as to divide the vessel 101 and separates out solids that are a target of separation from the contents within the vessel 101; and a first reflective member 106 for reflecting microwaves that is disposed so as to divide the vessel 101 more to the first end part 1015a side than the outgoing part and is capable of transmitting at least the contents passing through the first filter 105. 本发明的课题是提供一种可有效率地进行微波照射的处理装置。本发明的解决手段是具备：容器101，其通过具有微波反射性的材料构成，并具有第一端部1015a及照射开口部1013，所述照射开口部1013是照射至内部的微波的出射部；第一过滤器105，其以分隔容器101的方式配置，并由容器101内的内容物中分离出成为分离对象的固形物；以及第一反射构件106，其在较出射部靠第一端部1015a侧以分隔容器101的方式配置，且可供通过至少第一过滤器105的内容物通过，并反射微波。
