At 4, the magnetron driving unit 10 is detected according to the detected temperature.
0, the motor drive unit 120, the exhaust fan drive unit 130, the cooling fan drive unit 140, and the heater drive unit 150 are controlled. The magnetron drive unit 110 drives the magnetron 32 that generates a predetermined electromagnetic wave, and the motor drive unit 120 drives the motor 26 of the mixing unit. The exhaust fan driving unit 130 and the cooling fan driving unit 140 respectively drive the exhaust fan 43 of the purifying unit and the cooling fan 47 for cooling the magnetron 32.

Next, the operation of the apparatus of the present invention having the above configuration will be described. In FIG. 4, as in step S1,
After opening the lid of the charging port 12 and charging the organic waste into the fermenter 10, the waste disposal apparatus is driven as in step S 2. When the microprocessor 100 of the control means controls the magnetron driving unit 110 and the motor driving unit 120. , The exhaust fan, the cooling fan drive units 130 and 140, and the heater drive unit 150 are controlled, and the magnetron 32, the motor 26,

To heat the organic waste. The motor 26 rotates the shaft 22, and a mixing fan 24 formed on the shaft 22.
Agitates the organic waste put into the fermenter 10.

The temperature of the wind generated from the cooling fan 47 rises while cooling the magnetron 32, and flows into the combustion chamber 45 through the duct 48. On the other hand, when the organic waste is heated at an ultra-high frequency while being stirred as described above, a harmful gas containing ammonia and carbon dioxide is generated, and the moisture evaporates. It is forcibly exhausted. This harmful gas is supplied to catalysts 42 a and 42 b provided above and below the flue 40 and the heater 4.
The combustion and deodorization by 6 allows purified air to be released.

As described above, the organic waste is dried, and FIG.

Means that the moisture content of the waste as detected by the humidity sensor 52 is suitable for fermentation (typically 50
６０60%, and 50% in the present invention). As a result, if the water content of the exhaust gas does not reach the humidity suitable for fermentation, the magnetron 32 is continuously driven through the magnetron driving unit 110, and if the water content of the waste reaches the humidity suitable for fermentation, FIG. As in step S4, the microprocessor 100 controls the magnetron driving unit 100 to stop the operation of the magnetron 32. After this stoppage, the user may be notified that the water content of the organic waste is suitable for fermentation by a sound or a lighting lamp.

After that, since the temperature in the fermenter 10 is high, the operation of the magnetron 32 is stopped for a predetermined time, and the organic waste is cooled. afterwards,
As shown in step S5 in FIG. 4, the temperature suitable for fermentation detected by the temperature sensor 54 (differing depending on the strain, usually 5
When the temperature reaches 0 to 60 ° C. and the temperature is 55 ° C. in the present invention), a predetermined amount (usually 0.4% of the amount of organic waste treated) of the strain is introduced into the inlet 12 as in step S6. .

Here, the above-mentioned strain can be administered automatically by providing another strain administration means, and the user can manually input the strain by displaying the administration time of the strain by means of a buzzer sound or a lighting lamp.

After the administration of the strain into the fermenter 10, the microprocessor 100 senses the temperature in the fermenter 10 through the temperature sensor 54. If the temperature in the fermenter 10 is equal to or lower than the temperature suitable for fermentation (50 ° C. in the present invention) as in step S7, the microprocessor 100 proceeds to step S8.
As described above, the magnetron driving unit 100 is controlled to operate the magnetron 32. If the temperature is higher than the temperature suitable for fermentation (60 ° C. in the present invention) as in step S9, the magnetron driving unit 110 is controlled as in step S10. To keep the operation of the magnetron 32 stopped.

At this time, the air required for fermentation is supplied to the air inlet 1
7 inflow.

Thus, during the fermentation process, the fermenter 1
The output of the magnetron 32 is adjusted so that the internal temperature of 0 is maintained at 50 to 60 ° C. which is the optimum condition for fermentation. During the course of the fermentation process, the harmful gas generated in the fermenter 10 is forcibly exhausted through the exhaust hole 41 by the exhaust fan 43 in the flue 40. During the process of passing through the flue 40, the harmful gas is burned and deodorized by the heater 46 and the catalysts 42a and 42b, and then discharged to the outside. This fermentation process is continued until the moisture content detected by the humidity sensor 52 reaches a predetermined value (20% in the present invention) at which the fermentation is interrupted, as in step S11.

When the water content reaches a predetermined value through the fermentation process as described above, the microprocessor 100, as in step S11, sets the magnetron driving unit 110 and the motor driving unit 120, the exhaust fan and cooling fan driving units 130,
The operation of the heater 140, the heater driving unit 150, and the like is stopped.
At this time, it is also possible to display that the processing of the organic waste has been completed through a buzzer or a lighting lamp.

The organic waste fermented through the above process is taken out through the outlet 15 and can be reused as livestock feed or fertilizer. This fermentation process may take a little time depending on the type of organic waste,
It will be finished after about 40 hours.
