When drying of garbage is started, the opening and closing valve 61 is opened, and at the same time the processing tank 21 is heated by the heater 31. Due to the foregoing, temperatures in the processing tank 21 and the heating chamber 30 are raised and water contained in garbage in the processing tank 21 starts evaporating. At a point of time when the heating chamber 30 and the condensing chamber 40 are filled with this steam, the opening and closing valve 61 is closed, and the fan 50 is operated, so that steam in the condensing chamber 40 is cooled and condensed. Therefore, steam generated in the heating chamber 30 flows into the condensing chamber 40, and pressure in the heating chamber 30 becomes negative and the boiling point is lowered. Accordingly, it is possible to evaporate water at a low temperature. Almost all of the offensive smell components generated from garbage are dissolved in condensed water and discharged into the drainage pipe 1 in the middle of the drying process or after the completion of the drying process. <IMAGE> |
