1aの通電制御の自動化が可能となる。Here, the temperature of the garbage processing material in the processing tank 3 is easily affected by the outside air temperature of the garbage processing apparatus 1. That is,
When the outside air temperature is low, the temperature in the processing tank 3 also decreases,
When the temperature of the garbage disposal material is lowered as described above, microorganisms in the garbage disposal material are less likely to be active, and thus there is a problem that the garbage disposal efficiency is reduced. Therefore, processing tank 3
The temperature inside the processing tank 3 is controlled by energizing the surface heater 21a attached to the outer wall surface 3a of the garbage processing. First, the outside air temperature detection sensor 13 detects the outside air temperature of the garbage processing apparatus 1. Then, the detected temperature information is input to the control means 6. The control means 6 controls the energization of the surface heater 21a at a duty ratio (see Table 1) corresponding to the outside air temperature. In this manner, by driving the surface heater 21a at a duty ratio corresponding to the outside air temperature, overheating of the surface heater 21a can be effectively prevented, and the frequency of ON / OFF of the bimetal 23 for opening and closing the contact of the surface heater 21a can be reduced. It can be kept as low as possible. Further, by controlling the energization of the surface heater 21a at a duty ratio corresponding to the outside air temperature, even if the structure is such that the surface heater 21a is covered with a heat insulating material 22 for a cold region, or even if the outside air temperature becomes high, The overheating of the surface heater 21a can be effectively prevented, and the bimetal 2
3, the contact life of the bimetal 23 can be secured by reducing the ON / OFF frequency of the surface heater 21.
The reliability of the contact opening / closing a can be maintained for a long period of time. Moreover, by detecting the outside air temperature by the outside air temperature detection sensor 13 and inputting the temperature information to the control means 6, the surface heater 2 at a duty ratio corresponding to the outside air temperature is detected.
It is possible to automate the energization control of 1a.
