The exhaust pipe 13 is exhausted through the space between the intake pipe 12 and the exhaust pipe 13. Since the exhaust pipe 13 is divided into front and rear by the rear wall of the processing tank 1, the air sucked from the intake pipe 12 passes through the circulation path. While circulating in the processing tank 1, a part of this air is exhausted from the rear portion of the exhaust tube 13 through the exhaust passage 14 to the outside through the exhaust port 15.

Then, the lid 28 is opened, and an organic substance such as garbage is put into the processing tank 1 through the feeding opening 27 to close the lid 28. The detection means (not shown) detects the closing of the lid 28, and the control circuit energizes the electric motor 20, the planar heater 3 and the fan 18 based on the output thereof.

When the electric motor 20 and the planar heater 3 are energized, the agitator 22 rotates 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 carbon dioxide and water by aerobic microorganisms cultured on the carrier 2 and composted.

The air taken into the main body case is heated by the planar heater 3 and is mixed with the air circulating in the processing tank 1, so that the outside air temperature in winter or the like is low. Even at this time, it is possible to prevent a decrease in the organic substance processing capacity without significantly lowering the temperature in the processing tank 1.

The temperature of the treatment tank 1 depends on the place where the carrier 2 is present,
A clear difference occurs from the place where the carrier 2 does not exist, and the place where the carrier 2 exists becomes higher.

Utilizing this principle, the bulk of the carrier 2 is determined based on the temperatures detected by the first thermistor 4, the second thermistor 5, the third thermistor 6, and the fourth thermistor 7, which detect the temperature of the processing tank 1. Guess and display the results,
Operate according to the bulk. The control will be described based on the flowchart shown in FIG.

The lid 28 is opened, and an organic substance such as garbage is put into the processing tank 1 in which a predetermined amount of the carrier 2 is stored from the charging opening 27.
The lid 28 is closed. The detection means (not shown) detects the closure of the lid body 28, and the control circuit energizes the electric motor 20, the planar heater 3 and the fan 18 based on the output, and sets the number of times the stirring body 22 is agitated and the planar heater 3 is set. The operation is performed in a normal state in which the temperature and the rotation speed of the fan 18 are preset.

Then, in step S1, it is judged whether or not a predetermined time has passed since the previous detection, that is, 24 hours in the present embodiment, and when the predetermined time has passed, the fourth thermistor 7 is operated in the processing tank 1 in step S2. Air temperature T _O
Is detected. Since the temperature of the carrier 2 in the processing tank 1 is affected by the temperature of the air in the processing tank 1, T detected in step S2
Let _{O be} the reference temperature for determining the bulk of the carrier 2. In step 3, the temperature T ₁ of the processing tank ₁ is detected by the first thermistor 4. Then, in step S4, T ₁ detected in step S3 is compared with the reference temperature T ₀ detected in step S2.

If T ₁ -T ₀ is larger than the predetermined value in step S4, it is judged that the bulk of the carrier 2 is equal to or higher than the lower limit level, and the temperature T ₂ of the processing tank 1 is detected by the second thermistor 5 in step S5. To do. Then, step S6
In, the T ₂ detected in step S5 is compared with the reference temperature T ₀ .

If T ₂ -T ₀ is larger than the predetermined value in step S6, it is determined that the bulk of the carrier 2 is equal to or higher than the standard level, and in step S7, the temperature T ₃ in the processing tank 1 is controlled by the third thermistor 6. To detect. And step S
8, the T ₃ detected in step S7 and the reference temperature T ₀

In step S1, the LED 31 that indicates that the carrier amount on the display unit 29 is standard is turned on, and normal operation is continued.
Move to

If T ₃ -T ₀ is larger than the predetermined value in step S8, it is judged that the bulk of the carrier 2 is equal to or higher than the upper limit level, and in step S10 the LED 32 indicating that the carrier amount of the display unit 29 is large. Is turned on, and in step S11, the number of times of stirring of the stirring body 22 is increased, the set temperature of the planar heater 3 is raised, and the operation of the fan 18 is strengthened. Then, in step S12, 1 is added to N whose initial value is 0, and it is determined in step S13 whether N has become 3. When N is not 3, the process proceeds to step S1, and when N is 3, that is, when the level of the carrier 2 is equal to or higher than the upper limit level for 3 days, the organic substance is put into the display unit 29 in step S14. The LED 33 for prohibiting is turned on and an alarm is issued to inform the user of the replacement time of the carrier 2.

Before using the organic substance treating apparatus, when the amount of the carrier 2 supplied to the treating tank 1 in advance is extremely small, T ₁ is almost the same as T ₀ in step S4 and T ₁ -T ₀ is within a predetermined range. Therefore, the control unit determines that the bulk of the carrier 2 is below the lower limit level and the supply amount of the carrier 2 is insufficient.

Then, in step S15, the LED 34 for indicating carrier replenishment of the display unit 29 is turned on, an alarm such as a buzzer is issued, and in step S16, the number of times of stirring of the stirring body 22 is decreased to set the temperature of the planar heater 3. And the operation of the fan 18 is stopped to prevent the carrier 2 from drying, and the process proceeds to step S2.

By shifting to step S2, the alarm is continued and the carrier 2 is replenished until the carrier 2 is replenished.
When the carrier 2 is replenished with a predetermined amount, the alarm is immediately released and the process proceeds to the next step.

If the amount of the carrier 2 to be supplied to the processing tank 1 is small before using the organic substance processing apparatus, in step S6, T ₂ is almost the same as T ₀ and T ₂ -T ₀ is predetermined. Since it falls within the range, the control unit determines that the bulk of the carrier 2 is between the lower limit level and the standard level. And step S

Calculate ΔI ₃ . Then, in step S8 ′, ΔI ₃ calculated in step S7 ′ is compared with the reference current change value ΔI ₀ .

In step S8 ', if ΔI ₃ is substantially equal to ΔI ₀ and ΔI ₃ −ΔI ₀ is within the predetermined range, it is determined that the bulk of the carrier 2 is between the standard level and the upper limit level, and the step is performed. In S9 ', the LED 31 indicating that the carrier amount on the display unit 29 is standard is turned on, and the normal operation is continued to shift to step S1'.

If ΔI ₃ −ΔI ₀ is larger than the predetermined value in step S8 ′, it is determined that the bulk of the carrier 2 is above the upper limit level, and in step S10 ′ it is displayed on the display unit 29 that the carrier amount is large. The LED 32 is turned on, and in step S11 ′, the number of times the stirring body 22 is stirred is increased, the set temperature of the planar heater 3 is raised, and the operation of the fan 18 is strengthened.

Then, in step S12 ', 1 is added to N whose initial value is 0, and in step S13' N is 3
