The stirring is performed by the stirring plate 18 and the stirring blade 19. It is needless to say that it is not necessary to provide both the stirring plate 18 and the stirring blade 19, and at least one of them may be provided. Further, heaters 20 serving as heating means are disposed outside the rotary drum 6. These heaters 20 are heated by a deodorizing means described later, that is, after being heated by the catalyst heater 25, the heaters 20 are disposed inside the rotary drum 6. When the air returning to the garbage is not high in temperature, the garbage 4 is additionally heated and dried. The heater 20 only needs to be provided at at least one of the external position of the rotary drum 6 or the rotary drum 6 itself. As such a heater 20, an electric heater, a far infrared heater, or the like is generally used. is there.

A filter 27 for removing foreign matter is interposed between the unified drum-side outlet end 22a and the container-side outlet end 22b and the suction side of the blower blower 23. Then, the return end portion 22c of the closed circulation pipe line 22 is drawn from near the top surface on the side surface of the first hermetic chamber 7, and then, through a rotary joint 26 called a rotary joint or the like, and with the hollow structure of the rotary drum 6. The air blown into the rotary shaft 15 from the return end portion 22 c is heated to the kitchen waste 4 by blowing it out inside the kitchen waste 4 stored in the rotary drum 6. It is supposed to dry.

In the configuration of FIG. 1, the drum-side lead-out end 22a of the closed circulation pipe 22 is drawn out from near the bottom of the side surface of the first hermetic chamber 7. However, the configuration is not limited to such a configuration. Therefore, it is also possible to adopt a modified structure as shown in FIG. That is, in this modified example, the drum-side lead-out end 22a and the return end 22c of the closed circulation pipe 22 have a double-pipe structure, and the drum-side lead-out end is an outer passage having a double-pipe structure. The portion 22a is opened on the top side in the first hermetic chamber 7 and is unified with the container-side outlet end portion 22b, while the return end portion 22c, which is an inner passage of the double pipe structure, is As in the case of 1, it is connected to the rotating shaft 15 of the rotating drum 6 via a rotating joint 26. When the drum-side lead-out end 22a and the return end 23b of the closed circulation pipe line 22 have a double-pipe structure, the hermetic sealing portion is concentrated, resulting in hermetic sealing. Reliability is improved.

The refrigerator 24 further includes a compressor 28 for compressing the vaporized refrigerant, a radiating pipe 29 through which the compressed refrigerant flows, a condenser 30 for liquefying the compressed refrigerant, and a condenser 30 for liquefying the compressed refrigerant. A cooling pipe 31 for removing moisture in the air flowing through the closed circulation pipe line 22 as the gas evaporates, and the cooling pipe 31 is provided with a water separating section 32 provided on the discharge side of the blower blower 23. The heat radiating pipe 29 is wound around the outer periphery of the closed circulation pipe 22 through which the air from which moisture has been removed flows. That is, it is not necessary to wind the heat radiating pipe 29 around the closed circulation pipe line 22, but with such a configuration, moisture before flowing into the catalyst heater 25 and heated is removed. The advantage that the heated air can be preheated by the radiating pipe 29 is secured.

The air from which moisture has been removed by the moisture separating section 32 is heated by the heater 36, and at the same time, the odor component is removed by the catalyst 37. By the way, in this case, the heat generated by the oxidation reaction of the catalyst 37 is also taken in by the air, and when the catalyst 37 constituting the catalyst heater 25 removes the odor component by the oxidation reaction. Since the oxygen in the air flowing through the closed circulation pipe line 22 is consumed by the oxidation reaction at the time of deodorization, the garbage 4 stored and dried in the rotary drum 6 is heated to a temperature higher than the ignition point. Even if it is heated to the maximum, the advantage that there is no risk of fire occurring is ensured.

Further, the high-temperature air heated and deodorized by the catalyst heater 25 flows through the closed circulation pipe 22 and is supplied to the rotating drum 6 disposed in the first hermetic chamber 7. The air is blown out from the return end 22c of the closed circulation pipe 22 connected to the rotary shaft 15 into the rotary drum 6, and the kitchen waste 4 stored in the rotary drum 6 is heated with high-temperature air. And dried as it is heated. If the heating of the air by the catalyst heater 25 is insufficient, the air may be heated after another heater is installed in an appropriate place in the closed circulation pipe 22. .

In this case, a bypass pipe 38, which is connected to and bypasses the catalyst heater 25, is provided in the closed circulation pipe 22. The bypass pipe 38 and the catalyst heater are connected to each other. The catalyst heater 25 and the bypass pipe 3
The shut-off valves 39 and 40 used to allow air to flow after selecting one of the valves 8 are provided. That is, during normal kitchen waste treatment, air heating and deodorization are performed using the catalyst heater 25, but it is necessary to rapidly cool the entire closed circulation pipeline 22 after kitchen waste treatment. In this case, the closing valve 39 is closed and the closing valve 40 is opened, and air is circulated while flowing not in the catalyst heater 25 but in the bypass pipe 38. Although not shown, a three-way valve may be used instead of the closing valves 39 and 40. Although not shown, various sensors such as a temperature sensor, a humidity sensor, and a flow rate sensor are arranged in the closed circulation line 22, and the sensors are used effectively during operation of the kitchen waste treatment apparatus. Is to be controlled.

Next, a description will be given of a garbage disposal method executed by using the garbage disposal apparatus having the above-described structure.

The moist air containing the odor component and the moisture generated from the air is led out of the first airtight chamber 7, and the moisture in the led out air is removed by the moisture separating part 32 of the closed circulation pipe 22. . Then, the air from which the moisture has been removed is preheated by the radiating pipe 29 of the refrigerator 24 and then the catalyst heater 2 is heated.
5 and is heated to a temperature of about 120 to 130 ° C. by the catalyst heater 25, deodorized, and then flows through the closed circulation pipe 22 and returns to the rotary drum 6. Then, the kitchen waste 4 is heated and dried. In the garbage processing apparatus according to the present embodiment, almost complete airtightness and airtightness are achieved, and the air flowing through the rotary drum 6 and the closed circulation pipe 22 is heated.
