In the above configuration, the waste 4 input from the waste input port 1 is stored in a waste storage bag 5 in the waste processing chamber 3.
Is stored in. When the microwave heating device 6 is operated after closing the waste inlet 1, the microwave starts heating the waste 4 in the waste storage bag 5. In particular, the microwaves are selectively absorbed by the moisture in the waste 4 and the water vapor 15
With the generation of the waste, the waste 4 dries. The generated water vapor 15 fills the waste treatment chamber 3 because the waste inlet 1 is sealed, and contacts the inner wall of the waste treatment chamber 3 to form dew, forming condensed water 16 and treating the waste. The water is discharged to the outside from a drain port 7 provided at the bottom of the chamber 3. Most of the water vapor 15 is condensed and is discharged from the drain port 7, but part of the water vapor 15 is discharged from the drain port 7 in the state of the water vapor 15.

As described above, the drying of the waste 4 can be promoted by performing the microwave heating without accumulating the water vapor 15 and the condensed water 16 in the waste treatment chamber 3. Further, the air 9 sent from the blower 10 to the heat recovery chamber 8 is subjected to heat exchange on the wall surface of the waste processing chamber 3, recovers the exhaust heat of the microwave heating, raises the temperature, and forms the hot air 13 to warm The air is sent from the wind inlet 14 to the waste treatment chamber 3. Then, the waste 4 is heated and dried by the warm air 13 together with the microwave. The waste 4 can be uniformly dried by heating the waste 4 from the inside with the microwave and heating the waste 4 from the outside with the warm air 13.

As described above, the heat efficiency can be improved by recovering the exhaust heat by the microwave heating and heating it with the warm air 13.

Further, in heating and drying using only microwaves,
The tar-like substance comes to adhere to the surface of the waste 4, but by using the microwave and the hot air 13 together, the generation of the tar-like substance can be suppressed.

After the treatment is completed, the entire waste storage bag 5 containing the waste 4 can be taken out, so that the waste 4 can be taken out without touching the hand, which is sanitary. Waste 4
Is heated in the waste storage bag 5, so that no dirt adheres to the inner wall of the waste treatment chamber 3.

Further, by forming the waste storage bag 5 from paper, the air permeability can be enhanced, so that the water vapor 15 generated from the waste 4 can be efficiently disposed without being blocked by the waste storage bag 5. It is discharged to the material processing chamber 3. further,
The use of paper makes it easier to handle the waste storage bag 5 after the processing.

Further, by coating the inner wall of the waste treatment chamber 3 with ceramic or fluorine, the waste water can be effectively treated without causing the condensed water 16 condensed on the inner wall of the waste treatment chamber 3 to adhere to the inner wall. The water can flow down to a drain port 7 provided at the bottom of the chamber 3. Further, by coating with ceramics or fluorine, even if dirt such as tar leaks from the waste storage bag 5, it can be prevented from adhering to the inner wall of the waste treatment chamber 3.

As described above, since the waste is heated by the hot air 13 from which the exhaust heat generated by the microwave heating is recovered, the thermal efficiency of the apparatus can be improved. Further, since the processed waste 4 is taken out together with the waste storage bag 5, the waste can be sanitarily treated.

In the above configuration, the operation of heating and drying the waste 4 by microwaves is the same as that shown in the first embodiment.

The air 9 sent from the blower 10 to the heat recovery chamber 8 recovers the exhaust heat of the microwave heating, raises the temperature, and generates hot air 13.
And is introduced into the warm air chamber 17 and sent to the waste treatment chamber 3 located below the warm air chamber 17.

As a result, the waste 4 is separated from the warm air 1 from above.
3, the heat transfer characteristics to the waste 4 can be improved. In addition, by sending the warm air 13 from above to below, the steam 15 generated from the waste 4 can be effectively sent to the drain 7 located at the lower part of the waste treatment chamber 3, and the steam 15 Of the condensed water 16 can be promoted, and the drainage performance of the condensed water 16 can be enhanced. Then, by directly using the microwave heating and the hot air 13 in combination, the waste 4 can be dried more uniformly with higher thermal efficiency.
