る。However, in the above-mentioned conventional example, when the food waste is decomposed by the microorganisms in the food waste treating material, water is generated, and when the water content of the food waste treating material is too high, There was a problem that the processing efficiency of food waste was reduced. Further, the temperature of the food waste processing material in the processing tank is easily affected by the outside air temperature of the food waste processing device. That is,
When the outside air temperature is low, the temperature in the treatment tank is also low, and when the temperature of the food waste treatment material is low in this way, the microorganisms in the food waste treatment material are less likely to act, which reduces the food waste treatment efficiency. There is a problem. Therefore, conventionally, for example, in Japanese Examined Patent Publication No. 2-10398, the temperature inside the processing tank is controlled by a temperature detecting device provided at the upper part of the processing tank, and the heater attached to the food waste processing apparatus is controlled by the detected temperature. The temperature inside the processing tank is controlled by turning on electricity. However, in such a method, since the temperature of the food waste treatment material is not directly controlled, even if the temperature in the air in the treatment tank can be controlled, the temperature of the food waste treatment material may be low, and A reduction in processing efficiency is inevitable.

The lid 7 of the food waste processing apparatus A is opened, the food waste is put into the processing tank 3 filled with the food waste processing material, the stirring blade 4 is intermittently operated at regular intervals, and the air supply fan 9 and the exhaust fan are also provided. 12 is operated intermittently at regular intervals to stir and mix the food waste processing material in which the microorganisms inhabit and the food waste, and bring them into contact with air to decompose the food waste by the microorganisms inhabiting the food waste processing material. At this time, the temperature inside the processing tank 3 is detected by the temperature sensor 13c. Next, the water content detection sensor 13 applies a voltage to the heating resistor 13b to raise the temperature of the water content detection sensor 13. On the other hand, in the treatment tank 3, raw garbage is decomposed by microorganisms in the raw garbage treating material to generate water, and the raw garbage treating material absorbs this water, and when the water content becomes high, the raw garbage containing much water The water content detection sensor 13 comes into contact with the waste treatment material, and the heating resistor 13
Since the heat radiation from b increases, the temperature rise of the sensor decreases as the water content increases (see FIG. 4). This temperature rise is detected by the temperature sensor 13c and input to the controller 6. The controller 6 obtains the water content of the food waste treating material from the current temperature of the food waste treating material and the temperature rise of the temperature sensor 13c. Then, when the obtained water content is out of the predetermined range set in advance, the control unit 6
Is included in the food waste treatment material by turning on the warm air heater 10 in the air passage 8 and turning on the air blowing fan 9 to supply hot air from the air passage 8 to heat the treatment tank 3. The water content is evaporated to a desired water content, and when the desired water content is reached, the control unit 6 switches off the warm air heater 10. Therefore, it becomes possible to automatically adjust the water content of the food waste treatment material to a predetermined water content.

The temperature T (° C.) of the raw garbage processing material in the processing tank 3 is detected by the temperature sensor 13c of the water content detection sensor 13 and input to the control unit 6. In the control unit 6, when the temperature T (° C.) of the food waste processing material is higher than the temperature T 0 (for example, 10 ° C.) necessary for efficiently processing the food waste (T> T 0 ).
Is kept as it is, but when the temperature is low (T <T 0 ), the controller 6 sends a heater-on signal to the warm air heater 10 provided in the air passage 8, whereby the warm air heater 10 is turned on. It turns on, and the air supply fan 9 turns on,
The inside of the processing tank 3 is continuously heated until T ≧ T 0 . After that, if T ≧ T 0 , it is detected by the temperature sensor 13c,
The control unit 6 transmits a heater-off signal to the warm air heater 10 to turn off the warm air heater 10. In this way, the temperature of the food waste treatment material is always T ≧ T 0 (eg 10
It is controlled so that the temperature becomes ℃ or higher).

という利点がある。That is, the water content of the food waste treatment material is 40% to 70%, which is the most effective in treating food waste by microorganisms.
If the water content is too high, air cannot be taken in, aerobic treatment cannot be performed, and it will rot. Further, the temperature condition where the microorganisms are easily activated is about 10 ° C. or higher, and when the temperature is 10 ° C. or lower, it becomes difficult for the microorganisms in the food waste treatment material to act, and the food waste treatment efficiency decreases,
As described above, not only can the water content detection sensor 13 control the water content of the food waste processing material to an appropriate state, but also by directly controlling the temperature of the food waste processing material,
The microorganisms can be placed in an environment where they can be more easily activated, and the temperature can be adjusted to the most effective temperature condition for the decomposition treatment of food waste by microorganisms, so that it is possible to prevent the garbage disposal efficiency from decreasing. There is an advantage that the odor of can be suppressed.

い。In this embodiment, when the temperature of the food waste processing material becomes equal to or lower than a certain temperature based on the detection signal from the temperature sensor 13c, the control unit 6 displays the food waste as shown in FIG. 3 (b). The heater part C of the processing device A (including both the warm air heater 10 and the planar heater 20 of the air passage 8) is operated at the same time to control the temperature of the food waste processing material to a certain temperature or higher, By heating the heater C, the temperature of the food waste processing material can be adjusted within an appropriate range. Further, as shown in FIG. 3C, the temperature inside the processing tank 3 may be adjusted by turning on and off the surface heater 20.

なうのが好ましい。Especially in cold regions or in regions other than cold regions, the temperature of the food waste treatment material may drop too much in the winter, and even if the water content of the food waste treatment material is appropriate, the temperature decreases. If you do too much, it becomes difficult for microorganisms to act,
Since the processing efficiency of food waste is deteriorated, in order to cope with this, the controller 6 controls the hot air heater 10 to be turned on / off and the surface heater 20 based on the signal of the water content value detected by the water content detection sensor 13. It is preferable to perform appropriate control according to the water content of the food waste treatment material by turning on / off the above, adjusting the air volume of the air supply fan 9 and the exhaust fan 12, and adjusting the stirring frequency of the stirring blade 4.

The temperature may be displayed by a visual display means or an audible display means, and based on this, the warm air heater 10 and the planar heater 20 may be turned on or water may be sprayed. In addition, the warm air heater 10 and the planar heater 20
