CIRCULATION TUBE AND MICROWAVE DEVICE HAVING THE SAME

摘要

PROBLEM TO BE SOLVED: To provide a microwave device capable of obtaining an adequate yield even with an increased throughput, and a circulation tube of the microwave device.SOLUTION: In a microwave device 100 which arranges a circulation tube 60 within a cavity resonator 30 for resonating a microwave and performs heat treatment on a liquid flowing in the circulation tube 60, the circulation tube 60 comprises: a tube part for heating 61 which heats the temperature of the liquid to a first temperature; and a tube part for temperature maintenance 62 which maintains the temperature of the liquid passing through the tube part for heating 61 within a scope between the first temperature and a second temperature that is higher than the first temperature.
