いう不都合点がある。The steam heating has problems of wastewater generation and the regulation of pressure vessels. Heating by a band heater or the like causes local overheating and poor heat transfer. In addition, in the heating by the circulation of hot air, heat transfer is poor by mere spraying, and there is a possibility of local overheating. Further, in the high frequency heating, there is a problem that local overheating occurs depending on the material after water evaporation. In addition, Japanese Patent Laid-Open No. 1-1
In the case of processing a material composed of a plurality of plastics having different melting points, such as a hemodialyzer, using the processing method and apparatus described in Japanese Patent No. 76486, many materials that do not melt depending on the processing temperature remain. Therefore, volume reduction (molding) is insufficient. In addition, due to heating by an electric heater and a far-infrared heater, in the case of a large waste such as a hemodialyzer, local overheating is likely to occur, and harmful gases such as hydrogen chloride gas may be generated from polyvinyl chloride. Further, in the crushing method using the crusher in the waste heating / sterilizing apparatus described in Japanese Utility Model Application Laid-Open No. 1-144040, the effect of volume reduction is not necessarily great, and furthermore, maintenance of the cutter of the crusher is necessary, In addition, there are inconveniences such as high noise and vibration, and need for many power sources. Further, in the apparatus for treating plastic waste described in Japanese Patent Publication No. 51-25470, sterilization is not intended at all, and since only the surface is coated with a melt, the stability of the molded product is reduced. There is a disadvantage that the sex is bad.

う問題もある。In the apparatus described in Japanese Patent Application Laid-Open No. 1-315383, a large processed material such as a used hemodialyzer and containing water therein can be easily lifted only by hot air circulation. Not warm, not enough sterilized,
In addition, there are many problems such as a long processing time. further,
Since the hemodialyzer is composed of a plurality of plastics, depending on the processing temperature, some that melt and some that do not melt coexist, and the volume cannot be reduced sufficiently.
Further, in the apparatus described in the above-mentioned Japanese Patent Application Laid-Open No. 1-263410, when treating a processed product composed of a plurality of plastics such as used hemodialyzers and tubes, a large amount of harmful substances such as hydrogen chloride are treated. Since gas is generated,
In addition to measures for the material of the device, a large-capacity exhaust gas treatment device is required for the treatment of exhaust gas, which makes the device complicated and large. Further, the method of reducing the volume by incineration with microwaves requires a lot of electric power, and the device itself becomes high temperature, which is not suitable for installation in a hospital or a clinic. Further, in a conventional processing apparatus using microwaves, since microwaves are applied to the entire heating chamber, a large amount of microwaves are wasted and the efficiency of heating, sterilizing, and reducing the volume of the processed material is not good. In addition to the above harmful effects, there is also a problem that the structure of the heating chamber door becomes complicated in order to prevent microwave leakage from the apparatus and maintain airtightness.

Then, the container 18 and the medical waste are heated by microwaves and circulating hot air. At this time, the circulating hot air is forced to flow only into the container 18, and at the same time, the microwave is irradiated only into the container 18. As a result, the processed material is efficiently heated, sterilized, melted or softened, and the volume of the processed material is easily reduced by the wind pressure of hot air without being pressed. After heating the medical waste, the hot air in the processing object container 18 flows out of the hot air passage hole 20 and is heated and circulated again.

収縮・減容化が促進される。As described above, the present invention has the following effects. (1) The circulating hot air is forced to flow only into the processing container, and the microwave is irradiated only into the processing container.
The heat transfer efficiency is higher than when microwave irradiation is performed on the entire heating chamber , and the heat treatment time is shortened. In addition, since local overheating can be prevented at the same time and uniform heating can be performed, it is not necessary to raise the hot air temperature so much. Further, when performing a waste treatment including polyvinyl chloride, generation of harmful gases such as hydrogen chloride gas due to local overheating can be suppressed. (2) The microwave is irradiated only into the processing container and does not leak into the heating chamber .
It is not necessary to install a mechanism for the heating chamber at the door of the heating chamber , and the heating chamber door only needs to consider maintenance of airtightness, and the structure is simplified. (3) Shrinkage and volume reduction of the processed material are promoted by the wind pressure of the hot air that flows in forcibly.
