Although not shown, the processing tank 1 is provided with a garbage processing material such as a woody strip in which microorganisms have inhabited. As the garbage disposal material, conventionally known woody flakes (for example, Japanese Patent Publication No. 2-10398, and Japanese Patent Publication No. 2-3076)
No. 0, Japanese Utility Model Publication No. 3-22385) can be used.

As shown in FIG. 1, a processing tank 1 is provided in the processing tank 1.
A moisture content detection sensor 3 for detecting the moisture content of the garbage processing material in the inside is provided. In the present embodiment, the moisture content detection sensor 3 detects a temperature increase due to the moisture content of the garbage processing material when the heat is generated by the heat generating resistor 3b and the heat generating resistor 3b. Temperature sensor 3c. That is, FIG.
As shown in FIG. 3, a heat generating resistor 3b and a temperature sensor 3c such as a thermistor are provided on the back side of a casing 20 formed of a good heat conductive material such as stainless steel, copper, or aluminum.
The moisture content detection sensor 3 is formed by molding this with a molding material 21 such as an epoxy resin, and the casing 20 is fixedly attached to the side or lower surface of the processing tank 1 with screws 22. . As the heating resistor 3b used here, various types such as a carbon resistor, a nichrome wire, and a Kanthal wire can be used. The heating resistor 3b is turned on and off by a signal from the control unit 8, and temperature information detected by the temperature sensor 3c is input to the control unit 8. In addition, in the detection of the water content by the water content detection sensor 3, the stirring means 2 is controlled by a signal from the control means 8 so that the stirring means 2 is stirred for a certain time immediately before the detection.

FIG. 4 is a block circuit diagram of the present invention. A is a water content adjusting means, which is controlled by a control means 8. Thus, the garbage processing apparatus having the above configuration opens the lid 15 and puts the garbage into the processing tank 1 filled with the garbage processing material, and operates the stirring blade 2 intermittently at regular intervals. In addition, the air supply fan 5 and the exhaust fan 12
Is operated intermittently at regular time intervals, and the garbage disposal material in which microorganisms inhabit and the garbage are stirred and mixed and brought into contact with air to decompose the garbage by the microorganisms living in the garbage disposal material. .

When detecting the water content of the garbage processing material including garbage in the processing tank 1, the heating resistor 3b is turned on by a signal from the control means 8, and the heating resistor 3b generates heat. The change in the thermal conductivity due to the water content of the garbage disposal material at the time of the heating is a change in the temperature rise. Therefore, the temperature rise is detected by the temperature sensor 3c to detect the water content. Prior to this, the stirring means 2 is first turned on by a signal from the control means 8 to stir the inside of the processing tank 1. As a result, the components in the processing tank 1 are uniformly mixed, and the water content in each component varies. After the inside of the processing tank 1 is uniformly stirred by the stirring means 2 as described above, the moisture content detection sensor 3 is turned on by a signal from the control means 8 to detect the moisture content. That is, the heating resistor 3b is turned on, and the heating resistor 3b is turned on.
The temperature sensor 3c detects a temperature rise due to the moisture content of the garbage processing material when the material is heated by the temperature sensor 3c.
The temperature information detected in step c is input to the control means 8. Then, the water content of the garbage processing material is determined from the temperature of the garbage processing material and the temperature rise of the temperature sensor 3c. In this way, the water content of the garbage disposal material is obtained based on the temperature information from the temperature sensor 3c. When the water content is out of the set range, the water content adjusting means A The water content is adjusted automatically or manually to a predetermined moisture content. That is, when it is determined that the water content of the garbage processing material is too high, the heater 10 as the water content adjusting means A is turned on by the signal from the control means 8 and the air supply fan 5 is turned on to generate hot air. The water contained in the refuse treatment material is evaporated until the target water content is reached.

In this way, the garbage disposal material is adjusted to the water content most effective for the garbage disposal by microorganisms. The most effective moisture content of the garbage disposal material for treating garbage with microorganisms is 40% to 70%. If the water content is too high, air cannot be taken in, aerobic treatment cannot be performed, and rot will occur. In addition, in normal use, since the garbage is dumped and used every day, as a general tendency, the water content of the garbage disposal material will not be too low,
As the water content adjusting means A, it is only necessary to provide a heater 10 for lowering the water content of the garbage disposal material. In another embodiment, a water supply device (not shown) may be provided as the water content adjusting means A in addition to the heater 10. That is, when the detected water content is equal to or less than the predetermined value, the control means 8 supplies water from the water supply device to the garbage processing material in the processing tank 1. Here, in the above embodiment, an example is shown in which the water content adjusting means A is turned on and off by a signal from the control means 8 to automatically adjust the water content, but a water content detection sensor is used. The signal detected by 3 is input to the control means 8 and the water content is displayed by a display means (not shown), or when the water content is higher than a certain value or lower than the certain value, it is visualized. The information may be displayed by a display means or an auditory display means, and the heater may be turned on manually or water may be sprinkled based on the display.

In the present invention, as described above, the stirring means 2 is used immediately before the measurement by the moisture content detection sensor 3.
In addition to controlling to perform the stirring by the above, the stirring means 2 is turned on by a signal from the control means 8 after a predetermined time has elapsed from the measurement of the moisture content by the moisture content detection sensor 3, and the inside of the treatment tank 1 is kept for a certain time. You may make it stir for a fixed time. That is, unless stirring is performed after the moisture content measurement, the dried garbage processing material is solidified by the heating resistor 3b of the moisture content detection sensor 3 so as to cover the moisture content sensor 3, and the next moisture content detection is performed. Although the measurement error in measuring the moisture content by the sensor 3 increases,
As in the present embodiment, after the water content is measured by the water content detection sensor 3, stirring is performed by the stirring means 2 for a certain period of time.
The dry garbage can be moved before it hardens,
The garbage disposal material can be prevented from hardening on the outer surface of the moisture content detection sensor 3.

Further, as another embodiment, in addition to controlling to perform stirring by the stirring means immediately before the measurement by the moisture content detection sensor 3, when the moisture content is measured by the moisture content detection sensor 3, At the same time, the control means 8 may control the stirring by the stirring means 2. Also in this case, it is possible to prevent the dried garbage processing material from hardening in a form that covers the moisture content detection sensor 3.
