The agitation shaft 4 is provided with the agitation shaft 4 provided upright, and the agitation shaft 4 communicates with the front and rear walls of the treatment tank 1 and is connected to an agitation motor 19 provided on the back surface of the treatment tank 1. It is connected. Further, the stirring rods 3a, 3b, 3c are erected at equal angles (every 120 ° C.) around the stirring shaft, and are equidistant (3a is the back side of the processing tank 1, 3c is the processing tank 1 The front side 3b is arranged at the center of 3a and 3c. The lower part of the processing tank 1 is formed in an arc shape in accordance with the rotation activation of the stirring rods 3a, 3b, 3c, and a tank heater for heating the carrier in the processing tank on the outer wall of the arc-shaped part (Second heating element) 5 and a tank heater temperature sensor 6 are provided to control the temperature of the tank heater 5. The tank heater 5 and the tank heater temperature sensor 6 are covered with a tank heater heat insulating material 7. It has been broken.

  In addition, an air intake passage 8 that communicates with the rear surface of the airframe and an exhaust air passage 9 that communicates with the lower surface of the airframe are provided from the upper rear side of the processing tank 1. A ventilation fan motor 10 is provided downstream of the air exhaust passage 9. The processing tank 1 is ventilated from the intake passage 8 through the exhaust passage 9 by driving the ventilation fan motor 10. In addition, a drying heater (second heating element) 11 and a drying fan motor 12 for sending warm air into the processing tank 1 are attached upstream of the intake passage 8 and are put into the processing tank 1. The garbage is dried by applying warm air to the organic matter such as the garbage. In addition, an outside air temperature sensor 13 for detecting the outside air temperature is attached in the vicinity of the drying fan motor 12.

  A humidity sensor 14 is attached to the right side of the lower rear outer wall of the processing tank 1. As shown in the enlarged view of FIG. 2, the humidity sensor 14 includes a U-shaped humidity measurement heater 15, a humidity measurement temperature sensor 16 provided at the center of the lower half circle of the humidity measurement heater 15, and An aluminum foil 17 that covers the humidity measuring heater 15 and has a hole in a position where the humidity measuring temperature sensor 16 is provided so as not to touch the humidity measuring temperature sensor 16; The heat insulating material 18 that covers the temperature sensor 16 is used. The aluminum foil 17 is for efficiently transferring the heat generated from the humidity measuring heater 15 to the treatment tank 1, and the heat insulating material 18 is used for measuring the outside air temperature to the humidity measuring temperature sensor 16. This is to block the influence. A control unit 20 performs each load control and sensor input processing, and a control board thereof is provided on the right side of the stirring motor 19 at the rear of the processing tank 1 so as to cover the humidity sensor 14.

  In the above configuration, when the apparatus is used, a certain amount of microbial carrier (wood chips such as sawdust) is put in the processing tank 1 in advance. And when processing organic substances, such as garbage, the said cover body 2 is opened, an organic substance is thrown into the said processing tank 1, and the said cover body 2 is closed. At this time, the detection means 21 detects the opening / closing of the lid 2 and starts controlling the tank heater 5, the ventilation fan motor 10, the stirring motor 19, the drying heater 11, the drying fan motor 12, and the like. When it is detected that the lid 2 is closed, the drying heater and the drying fan are also driven for a certain period of time to dry the thrown-in garbage. At the same time, the air blowing display in the display means is performed. The agitating motor 19 is intermittently driven to mix the microorganism carrier with the organic matter such as the garbage, and to give the microorganism an appropriate oxygen to activate it. The tank heater 5 is controlled by the control substrate 20 so that the tank heater temperature sensor 6 is about 40 ° C., and the temperature of the microorganism carrier in the processing tank 1 is always a temperature suitable for activating microorganisms. I am doing so. The ventilation fan motor 10 always rotates while the lid 2 is closed, and continues to send fresh oxygen into the treatment tank 1 and evaporates from organic matter such as garbage in the treatment tank 1. Steam is released outside the aircraft. In addition, after a certain period of time has elapsed since the start of operation, a process for measuring the humidity in the processing tank 1 is performed.

  Energization of the humidity measuring heater 15 is started after a lapse of a certain time from the start of operation, and the temperature of the humidity measuring temperature sensor 16 at this time is stored as the energization starting temperature of the humidity measuring heater 15. Next, when the temperature of the humidity measuring temperature sensor 16 reaches + 10 ° C. from the energization start temperature of the humidity measuring heater 15, the energization ending temperature of the humidity measuring heater 15 is set. When the energization of the humidity measuring heater 15 is finished, and the temperature of the temperature / humidity measuring temperature sensor 16 falls to the energization start temperature of the humidity measuring heater 15, the energization of the humidity measuring heater 15 is started again, and from the energization start temperature. When the temperature reaches + 10 ° C., the energization is terminated. The two energization times to the humidity measuring heater 15 are measured, and (first heater on-time ÷ second heater on-time) is stored as the current measured value. The humidity in the treatment tank 1 is judged according to this measured value, and the control of the pitch of the stirring shaft 4 is performed. Further, when the lid 2 is closed, the detection means 21 detects that the lid 2 is closed, energization of the drying heater 11 is started, and the drying fan motor 12 is driven. At this time, the time for driving the drying heater 11 and the drying fan motor 12 is set to a time stored as a predetermined value in the control board 20.

  FIG. 3 shows the display means 22 for displaying the operating state of the garbage processing machine. Among them, there are an operation display means 23, a blower display 24 and a setting means 25.

  The operation and action of the garbage processing machine configured as described above will be described below.

  When the garbage is put into the treatment tank 1, the lid 2 is opened and the garbage is put in, then the lid 2 is closed, and the detection means 21 detects that the lid 2 is closed. After the lid 2 is closed, the driving of the drying heater 11 and the drying fan 12 is started. The time for driving the drying heater 11 and the drying fan 12 is driven for about 5 hours (this time varies depending on the state) in which the input garbage is dried to some extent by the heat of the drying heater 11. Like that. Regarding the setting of this driving time, when the garbage is in a state containing a lot of moisture and mixed with the carrier in the treatment tank 1 as it is, the moisture content (humidity) of the carrier rises and in the worst case it is in the carrier. It is conceivable that the microorganisms die and cannot be processed. In order to prevent such a state, before the carrier and garbage in the treatment tank 1 are agitated, water contained in the garbage is evaporated to some extent to keep the carrier in a good state.

  Moreover, if the time during which hot air is continuously fed into the treatment tank 1 becomes long, not only the input garbage but also the carrier will be dried. If the carrier is too dry, the carrier itself becomes light and the carrier flies into the exhaust passage 9 in the treatment tank 1 to block the exhaust passage 9, so that gas generated when garbage is treated in the treatment tank 1 is generated. It is conceivable that a strange odor is generated when the lid 2 is opened. For these reasons, the drying heater 11 and the drying fan motor 12 are driven for about 5 hours. The state in which the drying heater 11 and the drying fan motor 12 are driven after the lid 2 is closed is referred to as preliminary drying, and the air blowing display means 24 in the display means 22 is turned on to display the display. To do. The set time for the preliminary drying is set according to the outside air temperature and the humidity of the carrier. The set time is as shown in FIG.

  When the lid 2 is opened during the preliminary drying state and the garbage is additionally charged into the treatment tank 1, the case where the garbage is additionally charged approximately 5 hours after the previous garbage charging is considered. The pre-drying state lasts for 5 hours, and the pre-drying state continues for about 10 hours together with the previous pre-drying time. During that time, the air blowing display means 24 is kept lit. In this state, the user may be distrusted and the state of the carrier may be inferior.

  Therefore, when the lid is opened and closed during preliminary drying, the time from the previous closing of the lid 2 to the opening of the lid 2 is measured by the timing means mounted on the control board 20, and the remaining time of preliminary drying Thus, control is performed so as to set a time for preliminary drying performed after the lid 2 is closed.

  First, if the remaining time of the previous preliminary drying is equal to or longer than the new preliminary drying set time, the previous preliminary drying remaining time is set as the new preliminary drying set time.

  For example, when the preliminary drying that was performed immediately before is set to 11 hours, the lid 2 is opened and closed after 3 hours, and a new preliminary drying starts from there, and when the new preliminary drying time is set to 5 hours, The remaining time for preliminary drying is 8 hours, which is longer than the newly set preliminary drying time of 5 hours. Since the remaining time is longer than the set time, the newly set preliminary drying time is 8 hours.

  Next, if the remaining time of the previous preliminary drying is equal to or shorter than the new preliminary drying set time, an average value of the previous preliminary drying remaining time and the new preliminary drying set time is set as the new preliminary drying set time.

  For example, when the preliminary drying that was performed immediately before is set to 11 hours and the lid 2 is opened and closed after 8 hours, the preliminary drying starts anew and the new preliminary drying time is set to 5 hours. The remaining time for the preliminary drying is 3 hours, which is shorter than the newly set preliminary drying time of 5 hours. Since the remaining time is longer than the set time, the newly set preliminary drying time is the average of the previous preliminary drying remaining time of 3 hours and the new preliminary drying set time of 5 hours, that is, 3 hours and 5 hours. 4 hours obtained by dividing the added 8 hours by the average value of 2 times by “2” is set as a new preliminary drying set time.

  By setting the preliminary drying time as described above, the garbage put into the treatment tank 1 can be dried and the carrier can be prevented from being dried too much.

(Embodiment 2)
Next, control of the garbage processing machine in the 2nd Embodiment of this invention is demonstrated. The same components as those in the first embodiment are denoted by the same reference numerals, and the description thereof is omitted.

  The temperature of the carrier in the treatment tank 1 is measured by a humidity measuring heater, and a preset time for preliminary drying is performed according to the temperature of the carrier. For example, when the preliminary drying time is set as shown in FIG. 5, a setting similar to the preliminary drying setting time based on the outside air temperature and humidity shown in the first embodiment can be performed.

  In addition, immediately after the garbage is put into the processing tank 1 and the lid 2 is closed, the stirring motor is driven so that the thrown garbage is stirred for a certain period of time so as to come near the humidity sensor 14. Thus, the humidity sensor 14 determines the humidity. Thereby, since the moisture content (humidity) of the thrown-in garbage can be approximately measured, the state of the thrown-in garbage can be detected. Control is performed so as to determine the pre-drying time based on the detected water content. For example, when the setting is performed as shown in FIG. 6, a setting similar to the preliminary drying setting time based on the outside air temperature and the moisture content shown in the first embodiment can be performed.

  In addition, according to the temperature in the processing tank 1 and the state of the input garbage, the rotation speed (air flow) of the drying fan motor 12 is controlled as shown in FIG. A setting similar to the pre-drying setting time based on the outside air temperature and moisture content shown in Form 1 can be performed.

  Further, by allowing the user to set the preliminary drying time according to the type of garbage thrown in by the setting means 25, it is similar to the preliminary drying setting time by the outside air temperature and humidity shown in the first embodiment. Such settings can be made.

  Further, during the preliminary drying, the stirring motor 19 is driven for less time and the number of times is reduced so that the thrown-in garbage is not submerged and mixed in the carrier, and the drying heater 11 is energized before the drying. The fan motor 12 is driven so that warm air is always sent into the processing tank 1 during preliminary drying. As a result, since warm air is reliably applied to the garbage put into the treatment tank 1, a pre-drying state for drying the thrown-in garbage is effectively performed.

  Further, after the preliminary drying is completed, the agitation motor 19 is operated for a long time so that the garbage and the carrier are sufficiently mixed. By mixing the dried garbage and the carrier, the activity of microorganisms in the carrier is activated and the subsequent processing can be performed reliably.

  As described above, the garbage processing machine according to the present invention enables full-scale operation in which a pre-drying process is performed for a certain period of time after the garbage is thrown in, and then the microorganism carrier is stirred and the process is performed while maintaining an appropriate state. Since the time required for the drying process is changed to the one that suits the user's feeling depending on the opening / closing state of the lid body, the equipment that needs to change the processing time depending on the use state, for example, the dry garbage disposal It can also be used for machines, heat-utilizing equipment and devices.
