The stirring blade 12 is fixed by penetrating the stirring shaft 11 and attaching a fixing member (not shown) such as an E ring to the penetrating portion so that the stirring blade 12 can be easily replaced by removing the fixing member. ing.

Reference numeral 13 denotes a moisture detection sensor mounted on the stirring shaft 11, which has a heating element and a temperature detection sensor built therein, and detects the temperature reached by the carrier 2 and the organic substance within a predetermined time when the heating element is energized. Then, the water content contained in the carrier 2 and the organic substance is detected. The moisture detection sensor 13 is arranged on the rotation locus of the stirring blade 12 on the rear side in the rotation direction of the stirring blade 12. Reference numerals 14 and 15 denote first and second sliding terminals of the moisture detection sensor 13 provided at the end of the stirring shaft 11, and 16 denotes a fixed terminal portion provided on the side surface of the treatment tank 1.

Reference numeral 24 denotes a charging opening formed on the upper surface of the upper case 23, the opening edge of which extends into the processing tank 1. Reference numeral 25 denotes a lid body which is swingably supported on the upper surface of the upper case 23, and which closes the opening 24 so as to be openable and closable.

Then, the lid 25 is opened, and an organic substance such as garbage is put into the processing tank 1 through the feeding opening 24 to close the lid 25. The detection means (not shown) detects the closure of the lid 25, and the control circuit energizes the electric motor 7, the planar heater 3 and the fan 6 based on the output thereof.

When the electric motor 7 and the sheet heater 3 are energized, the agitator 10 is rotated to mix the carrier 2 and the organic matter, and the temperature in the treatment tank 1 is set to an optimum range for activating aerobic microorganisms and the like. The organic matter is maintained and decomposed into a compost by aerobic microorganisms or the like cultured on the carrier 2.

Further, by energizing the fan 6, the air in the treatment tank 1 is circulated through a circulation path to evaporate the water generated by the decomposition of organic matter, and the water content of the carrier 2 is optimal for the activation of aerobic microorganisms. And maintain the oxygen content within the above range and supply oxygen necessary for activation of aerobic microorganisms. Part of the air that circulates in the processing tank 1 is exhausted to the outside of the main body case through the exhaust passage 5, and the air in the processing tank 1 is prevented from becoming over-humidified, and the moisture in the processing tank 1 is removed. Along with improving efficiency, it also aims to activate aerobic microorganisms and improve the ability to treat organic substances.

As the air in the processing tank 1 is exhausted to the outside, the outside air is taken into the main body case from the intake port formed in the lower case 22, and the processing tank is supplied from the suction port formed on the side surface of the processing tank 1. The air that is supplied into the main body case 1 is heated by the planar heater 3 and is mixed with the air that circulates in the treatment tank 1. Therefore, even when the outside air is low, such as in winter. It is possible to prevent a decrease in the organic substance processing capacity without significantly lowering the temperature in the processing tank 1.

Next, the control by the moisture detection sensor 13 will be described. The higher the moisture content of the carrier 2 or the organic substance, the higher the thermal conductivity, and the temperature of the carrier 2 or the organic substance is less likely to rise. The lower it is, the lower the thermal conductivity is,
The temperature of the carrier 2 and the organic substance easily rises. Utilizing this principle, the water content of the carrier 2 and organic matter is controlled to be maintained within the optimum range for activating the microorganisms.

That is, at the start point, the stirring member 10
The number of stirrings, the set temperature of the planar heater 3, and the air flow rate of the fan 6 are set in a normal state.
Then, a predetermined time has passed since the previous detection, that is, 2 in the present embodiment.
It is determined whether or not 4 hours have elapsed, and when a predetermined time has elapsed, the heating element of the moisture detection sensor 13 is energized to
13 temperature sensors are used for a predetermined time, 10 in this embodiment.
Detect the temperature reached in minutes.

When the temperature detected by the moisture detection sensor 13 is within a preset range, it is judged that the water content of the carrier 2 and the organic substance is in a good state, and the stirring number of the stirrer 10 and the planar heater 3 are determined. The operation in the normal state in which the set temperature and the air flow rate of the fan 6 are preset is continued.

When the temperature detected by the water content detection sensor 13 is lower than the preset range, it is determined that the water content of the carrier 2 and the organic matter is high, and the agitation number of the agitator 10
By operating the set temperature of the sheet heater 3 and the air flow rate of the fan 6 higher than the normal state, the evaporation amount of water in the carrier 2 and the organic substance is increased, and the water content of the carrier 2 and the organic substance is lowered.

When the temperature detected by the water content detection sensor 13 is higher than the preset range, it is determined that the water content of the carrier 2 and organic matter is low, and the agitation number of the agitator 10 and the planar heater 3 are determined. The set temperature and the number of rotations of the fan 6 are lower than in the normal state to reduce the evaporation amount of water in the carrier 2 and the organic matter and increase the water content of the carrier 2 and the organic matter.

The moisture detection sensor 13 is a stirring shaft of the stirring body 10.
Since it is attached to 11, the carrier 2 and organic substances are less likely to receive a large force when the stirring body 10 rotates, and the moisture detection sensor 13 is not damaged. Also, the moisture sensor 13
Is located on the rear side in the rotation direction on the rotation locus of the stirring blade 11 of the stirring body 10, so that the pressure of the carrier 2 and the organic substance is not applied to the moisture detection sensor 13 when the stirring body 10 rotates,
The moisture detection sensor 13 can be more reliably prevented from being damaged.

The carrier 2 is attached to the stirring blade 11 on the front side in the rotation direction of the stirring blade 12, and is fixed to the front side in the rotation direction of the stirring blade 12 due to the pressure received as the stirring body 10 rotates.
Since the moisture detection sensor 13 is disposed on the rear side in the rotation direction of the stirring blade 12 in the rotation direction, the carrier 2 does not stick to the moisture detection sensor 13 and the moisture content of the actual carrier 2 and the organic substance can be more reliably achieved. The rate can be detected.

In the above embodiment, the moisture detection sensor 13
Is disposed on the rear side in the rotation direction on the rotation locus of the stirring blade 12, but may be disposed at a substantially intermediate position between the adjacent stirring blades 12 as shown in FIGS. 4 and 5. As shown by the broken lines in FIGS. 4 and 5, the carrier 2 is fixed to the stirring blade 12 on the front side in the rotation direction of the stirring blade 12, and the fixed carrier 2 becomes gradually larger with long-term use. However, the moisture detection sensor 13
Is disposed at a substantially intermediate position between the adjacent stirring blades 12,
The moisture detection sensor 13 is arranged at the position farthest from the stirring blade 12, and the moisture detection sensor 13 is attached to the carrier 2
Is less likely to stick, and the actual water content of the carrier 2 and the organic substance can be reliably detected.

Further, the moisture detection sensor 13 may be arranged in a direction substantially perpendicular to the axial direction of the stirring blade 12 located in the vicinity as in the embodiment shown in FIGS. 6 and 7. In the above-described embodiment, the stirring blade 12 is configured to be easily exchanged by penetrating the stirring shaft 11 and attaching a fixing means such as an E ring to the penetrating portion. Therefore, as shown by broken lines in FIGS. 6 and 7, the carrier 2 is fixed to both ends of the stirring shaft 11 with respect to the stirring blade 12, but the moisture detection sensor 13
Are arranged in a direction substantially perpendicular to the axial direction of the adjoining stirring blades 12, so that the moisture detection sensor 13 is disposed at a position farthest from the stirring blades 12, and the moisture detection sensor
The carrier 2 is less likely to stick to the carrier 13, and the actual moisture content of the carrier 2 and the organic substance can be reliably detected.

In the present embodiment, the carrier 2 is used in all cases, but the carrier 2 may be omitted and organic substances and microorganisms may be put into the processing tank 1.
