Description

  The present invention relates to an extinguishable garbage processing machine that decomposes garbage generated in a kitchen of a home or a restaurant into water and carbon dioxide by the action of microorganisms and eliminates them.

  There are various types of conventional extinguishable garbage processing machines, but those exceeding a certain level are heated in a garbage processing tank placed in the main body case to keep the inside at an appropriate temperature. Or a deodorizing means for preventing the release of a strange odor to the outside environment, and further comprising an agitating means for agitating and mixing the raw garbage put into the inside and the substrate described later. ing.

  The agitating means is configured to rotationally drive various types of agitating blades or agitating rods by an electric motor, and many of them are rotationally driven when raw garbage is introduced and at appropriate time intervals. If the rotation is obstructed by obstacles such as foreign matter that may be thrown into the garbage processing tank together with the garbage, the increase in load caused by that is mechanically detected and used for driving. The power switch of the electric motor is turned off to ensure safety.

  Such an extinguishable garbage processing machine uses a base material configured by mixing microorganisms in a porous wood chip in advance in its garbage processing tank. When the garbage is put into the garbage treatment tank, as described above, the stirring means normally operates at each time and at a predetermined time interval to mix the garbage and the substrate well, and into them. Introduce air. And, as described above, the garbage is decomposed into water and carbon dioxide to disappear by the action of microorganisms in the substrate.

  At this time, as described above, when a heating means or the like for holding the inside of the garbage processing tank at an appropriate temperature is configured, since these act and the inside is held at a temperature suitable for the activity of the microorganism, The decomposition activity is efficiently performed. In the case where the deodorizing means is provided, the bad odor component is removed from the gaseous component exhausted from the garbage processing tank by the action, so that an advantage of not deteriorating the surrounding environment can be obtained.

  Further, when foreign matter is put into the garbage processing tank together with the garbage and this impedes the rotation operation of the stirring means, as described above, this is detected by the mechanical detection means, and the power switch is turned off. Rotation will be stopped. Thus, damage to the stirring blade (stirring bar) and the driving electric motor can be avoided. In addition, the foreign matter that has become an obstacle can be removed while stopping.

  However, when the detection means when the electric motor for driving the stirring means is overloaded is configured as a mechanical detection means as described above, there is a problem that it is not easy to configure at a low cost, and In the case of an overload, there is a problem that it may not be easy to remove foreign matter or the like that is the cause of the overload just by stopping the driving electric motor.

As an extinguishable garbage processing machine that has solved such problems, it is “an extinguishable garbage processing machine that decomposes input garbage into water and carbon dioxide, In an extinguishable garbage processing machine equipped with stirring means for rotating and stirring the input garbage,

If the detected current value of the current detecting means exceeds a reference value, it is determined that the stirring means is stopped by an obstacle during the rotating operation and the electric motor is overloaded. Controlling the power switch for supplying / stopping electric power to the electric motor and switching the forward / reverse direction of rotation, immediately stopping the electric power supply to the electric motor, and maintaining the stopped state for a certain short time. After the passage of time, the agitation means is switched to reversely rotate as much as necessary to remove possible obstacles, and then the electric power is supplied after the necessary reverse rotation operation is performed, and then the electric power supply is stopped again. There is a proposal of “an extinguishable garbage processing machine equipped with such control means” (Patent Document 1).

  The technique of Patent Document 1 can detect an overload applied to the drive electric motor with a relatively simple configuration, and is recognized to be excellent, but it is more convenient if it can be detected more simply and accurately. It is.

JP 2001-54780 A

  The present invention solves the problems in the prior art as described above, and is extinguished with detection means that can detect the electric motor that drives the stirring means when it is overloaded more easily and accurately. The problem to be solved is to provide a type garbage disposal machine.

1 of the present invention is an extinguishable garbage processing machine that decomposes input garbage into water and carbon dioxide, and includes a rotating stirring means for rotating and stirring the input garbage into a garbage processing tank. In an extinguishable garbage processing machine,
The tachometer generator that rotates in conjunction with the rotation of the rotation shaft of the rotating stirring means is attached, and the output voltage of the tachometer generator is a reference while the rotating stirring means is driven to rotate by an electric motor that rotates the rotating stirring means. When the value is lower than the value, the rotation stirring means is restricted in its rotation by the obstacle during the rotation operation, and it is determined that the electric motor is overloaded, and the electric power is supplied to the electric motor.・ Control the power switch that performs forward and reverse switching of the stop and rotation direction, immediately stop the supply of power to the electric motor, and after a certain short period of time in the stop state, possible obstacles A control means for switching the rotational stirring means to reversely rotate as much as necessary for removing the electric power, supplying the electric power, performing the reverse rotational operation as much as necessary, and then stopping the electric power supply again. Is an example was annihilation type garbage processing machine.

  In the present invention No. 2, in the extinguishable garbage processing machine of the present invention No. 1, a warning light for turning on when the electric motor is determined to be overloaded is added as a notification means. It is a thing.

  According to the extinguishable garbage processing machine 1 of the present invention, for example, a foreign object such as a special hard and large piece of wood different from normal garbage is put into a garbage processing tank, and this collides with the stirring means. Alternatively, when the stirring means is sandwiched between the bottom of the garbage disposal tank and the rotation of the stirring means is impeded, the stirring means is rotated at a predetermined rotational speed. If it is detected that the output voltage of the tacho-generator is reduced and this value falls below a reference value, the control means The electric motor that drives the agitating means is temporarily stopped by the control means, and after a predetermined short time has passed, it is controlled to rotate slightly backward and then stop again. The agitating means and the electric motor Etc. Those that would be. In addition, this can be reliably realized with a simple configuration.

  According to the extinguishable garbage disposal machine 2 of the present invention, the notification means reliably notifies the user and other related parties that the above-described overload state of the electric motor has occurred.

  The extinguishable garbage processing machine of the present invention basically has a garbage processing tank for decomposing the input garbage into water and carbon dioxide, and the garbage in the garbage processing tank. Rotating agitating means for rotating and agitating, an electric motor for rotating the rotating agitating means, a power switch for supplying / stopping electric power to the electric motor and switching the rotation direction between forward and reverse, and rotation of the rotating agitating means When the output voltage of the tachometer generator that rotates in conjunction with the rotation of the shaft and the tachometer generator falls below the reference voltage during the stirring operation of the rotating stirring means, the power switch is controlled to Immediately stop the supply of power, and after a certain short period of time in the stopped state, supply power by switching the rotating stirring means to reversely rotate as much as necessary to remove possible obstacles. As many reverse turns After the operation, and control means so as to stop the supply of the electric power again, in those configured.

  Basically, the garbage processing tank is not required to have a specific configuration as long as it is a container capable of processing the input garbage. Of course, because of the relationship with the rotary stirring means, it is necessary to satisfactorily stir the garbage thrown in by the rotation, so that the lower half is a downward half as viewed from the direction perpendicular to the rotation axis of the rotary stirring means. It is preferably configured in an arc shape. In addition, it is appropriate to arrange a heating means on the outer periphery of the bottom of the garbage processing tank in order to keep the introduced garbage at an appropriate temperature.

  The garbage disposal tank preferably includes an intake / exhaust means for introducing and exhausting air into the interior. This garbage disposal tank is used for oxidative decomposition of garbage, which is an organic waste, by aerobic microorganisms. For this purpose, it is important that air is introduced satisfactorily. Further, when exhausting by such an intake / exhaust means, an odor adsorbing means is preferably arranged at the exhaust port. An off-flavor may be generated during the processing of raw garbage, and it is preferable to adsorb it and prevent it from being discharged to the outside.

  The rotating stirring means is not limited to a specific one as long as it can stir the garbage in the garbage processing tank well and uniformly introduce air while crushing coarse garbage. For example, it can be composed of a rotating shaft and a stirring bar attached in a state orthogonal to the rotating shaft. If necessary, the stirrer can be provided with a blade near the tip. The peeled fruits and the like tend to be prevented from being decomposed by microorganisms due to the skin, but the purpose is to facilitate the decomposition by scratching even slightly.

  The electric motor is not limited to a specific configuration as long as it can drive the rotary stirring means and can perform the predetermined control by the control means via the power switch. . It is also possible to adopt a free transmission means for the rotational force from the electric motor to the rotary stirring means.

  The tacho generator is arranged to rotate in conjunction with the rotation of the rotation shaft of the rotary stirring means, and detects the rotational speed of the rotary stirring means at that time based on the output voltage. By detecting whether or not the output voltage is lower than the reference value, it is determined whether or not the rotation stirring means is restricted in its rotation by some obstacle during the rotation stirring operation, and the electric motor is overloaded. It is something to be judged. Therefore, the tachometer generator that can achieve such an object is not limited to that of a specific configuration, and an appropriate one can be freely adopted. Since the purpose is to perform accurate detection at a relatively low speed rotation, it is preferable to satisfy such a purpose.

  The tacho generator is used for the purpose as described above, and is directly connected to either the electric motor, the rotation stirring means, or the rotation transmission means interposed between the two, and the rotation speed thereof is set. Should be arranged to detect. The reference value should be appropriately set depending on where it is arranged.

  As the power switch, one having a function as described above can be freely adopted.

  The control means can freely adopt at least the function as described above. For example, this can be easily configured by a microcomputer and software.

  Note that such an extinguishable garbage processing machine can be provided with a warning light for turning on when it is determined that the electric motor is overloaded as a notification means.

  Therefore, according to the extinguishable garbage processing machine of the present invention, the garbage thrown into the garbage processing tank is divided into the base material that has been put in advance by the rotating stirring means that rotates and the raw food that has been put so far. Because it is agitated and mixed with garbage and at the same time, air is appropriately introduced between garbage debris, etc., the activity of microorganisms becomes active, and the activity gradually decomposes into water and carbon dioxide. Become. The rotary agitating means can perform a rotating agitating operation for a set time at set time intervals by giving such a function to the control means. Stirring and mixing and air introduction are performed.

  At this time, as described above, if the garbage processing tank is equipped with a heating means and an intake / exhaust means, the temperature condition in the garbage treatment tank is also improved, and the garbage decomposition activity is further improved. Will be done. At this time, if the odor adsorbing means is arranged in the garbage disposal tank, the malodorous component contained in the exhaust gas discharged to the outside is removed and the malodor is released to the surrounding environment. In other words, the user is not bothered by the bad odor when the lid of the garbage disposal machine is opened for the introduction of garbage.

  In the garbage processing tank, for example, when a foreign object such as a special hard and large piece of wood that is different from ordinary garbage is put in, and thereby the rotation stirring operation of the rotating stirring means is hindered, Along with this, the output voltage of the tacho-generator operating in conjunction with the rotation of the rotary stirring means will suddenly drop, and if this output voltage falls below the reference value, that is the fact that the control The power switch is controlled to operate the electric motor as will be described later.

  That is, the power switch is controlled by the control means, the supply of power is immediately stopped, the rotation of the electric motor is stopped, and after a lapse of a short time maintaining the stopped state, the electric motor is The electric power is supplied after switching the supply method, and the reverse rotation is performed as before, and the rotary stirring means is rotated in the reverse direction by an angle necessary for removing the foreign matter, and then the electric power is supplied again. Is stopped and its rotation is stopped. Thereafter, power is not supplied to the electric motor until the obstacle is removed and the control means is reset.

  In addition, if a warning light is added to the extinguishable garbage processing machine as described above, when the output voltage of the tachometer generator falls below a reference value, control is performed to turn on the warning light at the same time. Then, the blinking lighting or continuous lighting operation informs the user and other related parties that a foreign matter has interfered with the rotating stirring operation of the rotating stirring means. When the foreign substance is removed by the user or the like who has recognized the situation in this manner and reset together with the control means, the operation of the warning light is stopped and the normal operation state by the control means is restored.

  Thus, according to the extinguishable garbage processing machine of the present invention, the decomposition processing of the input garbage is performed satisfactorily in the normal processing process, and the rotation of the rotating stirring means is hindered in the garbage processing tank. Even when such foreign matter is thrown in, the abnormal reduction in the rotation speed of the rotating stirring means is easily and accurately detected by the output voltage of the tachometer being lower than the reference value, and the warning light is equipped. If this is the case, this is operated to notify the user and other related parties, and the rotation of the electric motor is stopped. Subsequently, after a short period of time has elapsed, the electric motor is reversed. It can be rotated to facilitate removal of foreign matter, and this can be realized quickly and accurately with a simple configuration.

  As shown in FIGS. 1 to 3, the extinguishable garbage processing machine of this embodiment includes a main body case 1, a garbage processing tank 2 housed in the main body case 1, and a rotating stirring means configured in the garbage processing tank 2. 3, an intake / exhaust means comprising an exhaust cylinder 4 and an intake port 5 coupled to the garbage processing tank 2, a heating means 6 disposed on the outer surface of the bottom of the garbage treatment tank 2, and the rotating stirring means 3.

  The body case 1 is a rectangular parallelepiped box-shaped member having an upper opening, and a lid 1b is arranged in the upper opening so as to be opened and closed freely through a hinge 1a as shown in FIGS. is there. In addition, a slit (not shown) for introducing air is opened at the lower part of the main body case 1.

  As shown in FIG. 1, the garbage processing tank 2 has a semicircular lower part when viewed from the front, and a side plate extending upward from both upper and front and rear end surfaces. The upper part is entirely open and opens toward the upper opening of the main body case 1.

  As shown in FIGS. 1 and 2, the rotating stirring means 3 includes a rotating shaft 3 b that is rotatably disposed on bearings 3 a and 3 a that are disposed on the front and rear side plates of the garbage disposal tank 2, and a direction perpendicular thereto. The three stirring rods 3c, 3c, and 3c arranged on the electric motor 3e are coupled to the electric motor 3e through a rotation transmission mechanism.

  When the three stirring rods 3c, 3c, 3c are arranged on the rotary shaft 3b and rotated, the tips of the three stirring rods 3c, 3c, 3c do not come into contact with the bottom surface of the garbage disposal tank 2, but move immediately before them. It shall be of the order.

  The rotation transmission mechanism is fixed to a large-diameter sprocket 3d fixed to one end of the rotating shaft 3b, the electric motor 3e disposed on the bottom of the main body case 1, and an output shaft of the electric motor 3e. A small-diameter sprocket 3f and a chain 3g spanned between the small-diameter sprocket 3f and the large-diameter sprocket 3d.

  The intake / exhaust means comprises the exhaust cylinder 4 and the intake port 5 as described above. As shown in FIGS. 1 and 2, the exhaust pipe 4 has an upper end opened to one side of the upper part of the garbage processing tank 2 and the other end opened to the bottom of the main body case 1. Further, a filter 4a, an exhaust means 4b, and an odor adsorbing portion 4c are arranged on the exhaust cylinder 4, respectively. On the other hand, the intake port 5 is configured to open into the gap space between the garbage processing tank 2 and the main body case 1 on the upper side of the garbage processing tank 2.

  Specifically, as shown in FIG. 2, the exhaust cylinder 4 has one end opened to a horizontal rectangular opening at the upper end of the garbage processing tank 2 and the other end via the exhaust means 4b. 1 is opened below the bottom. As shown in FIG. 1, the filter 4 a is disposed in an opening that opens to the upper side of the garbage disposal tank 2, and the odor adsorbing portion 4 c is disposed close to the filter 4 a and on the exhaust side thereof.

  The exhaust means 4 b is disposed on the bottom of the main body case 1 and is located on the outer end side of the exhaust cylinder 4. In this example, the filter 4a employs a member that mainly removes solid components such as dust, and in this example, the odor adsorbing portion 4c is an adsorption chamber and a bowl-like box that is freely inserted and removed. In this example, the exhaust means 4b is composed of a blower and an electric motor for driving the blower. It is composed of

  As shown in FIG. 1, the intake port 5 faces the opening of the exhaust pipe 4 to the garbage processing tank 2, opens to the upper part of the garbage processing tank 2, and A filter 5a similar to the filter 4a disposed on the exhaust tube 4 is disposed. When opening in the upper part of the garbage disposal tank 2 in this way, due to the arrangement relationship of the garbage disposal tank 2, this necessarily opens to the gap space between the garbage disposal tank 2 and the main body case 1. Become.

  In this example, the heating means 6 employs a sheet-like heater, which is attached to the lower surface of the garbage processing tank 2 in a joined state.

  The tacho generator 11 employs a direct current tacho generator in this example, and is attached with the rotating shaft coupled to the rotating shaft of the electric motor 3e, as shown in FIGS. The purpose is to obtain an output voltage according to the rotational speed of the electric motor 3e. Therefore, the output unit of the tachometer generator 11 is connected to the voltage detection unit 8 so that the output voltage is input to the voltage detection unit 8.

  As shown in FIGS. 1 and 2, the voltage detection unit 8 is attached to the electric motor 3e in the vicinity of the tachometer generator 11, and its circuit is shown in FIG. A smoothing circuit 8a that smoothes the direct current output of the tachometer 11 that detects the rotation of the rotating shaft of the motor 3e, and receives the voltage from the smoothing circuit 8a and divides the voltage by the resistance load circuit including the first resistor R1 and the second resistor R2. The voltage divided between the resistors R1 and R2 is input to the comparator 8b. On the other hand, the reference voltage generated by the reference voltage generator 8c is simultaneously input to the comparator 8b, and the voltage divided by the comparator 8b is input. Is compared with the reference voltage and the comparison result is output, the inverter 8d for inverting the output of the comparison unit 18a, and the inverted output of the inverter 8d are transmitted to the control means 7 at the next stage. Whether Luke, which is constituted by the output adjusting section 18b consisting of an AND gate 8e for on-off control at the other input.

  As shown in FIG. 3, the abnormality notification lamp circuit 9 outputs an output indicating that the reference voltage from the output adjustment unit 18b of the voltage detection unit 8 has fallen below (the rotation speed of the electric motor 3e has decreased to a predetermined value or less). (In this embodiment, when an H level one-pulse output) occurs, if this is input to the set input terminal of the reset set flip-flop 9a, its Q output becomes H level, and this is applied to one input terminal of the NAND gate 9b. The oscillation signal output of the oscillator 9c input and connected to the other input terminal of the NAND gate 9b appears at the output terminal of the NAND gate 9b, and the light emitting diode 9d connected to the output terminal of the NAND gate 9b flashes. It is configured to light up. The resistor R3 connected in series to the light emitting diode 9d is a current limiting resistor connected to the power source.

  The power switch 10 is composed of a relay group inserted in the middle of a power supply circuit that supplies power to the electric motor 3e. As shown in FIG. 4, X1 rotates the electric motor 3e forward. The electromagnetic relay X2 is an electromagnetic relay for reverse rotation, and is controlled by the control unit 7. TH is a thermal relay that opens a contact when a load current of a certain level or more continues for a required time.

  As described above, the control unit 7 includes the electric motor 3e that drives the rotary stirring unit 3, the normal operation of the exhaust unit 4b and the heating unit 6 of the exhaust cylinder 4, and the voltage detection unit 8 has a voltage drop. The operation at the time of abnormality of the electric motor 3e that drives the agitation means 3 at the time of detecting the above is controlled. More specifically, it is as follows.

  First, with regard to the rotary stirring means 3, normally, in this embodiment, the electric motor 3e is rotated 180 seconds forward, 10 seconds stopped, 180 seconds reverse, 10 seconds stopped, 180 seconds forward, 180 seconds stopped, 10 seconds reverse. The cycle of 180 seconds and stop 300 seconds is repeated, that is, the electromagnetic relay X1 is closed for 180 seconds, both the electromagnetic relays X1 and X2 are opened for 10 seconds, the electromagnetic relay X2 is closed for 180 seconds, the electromagnetic relay X1 And X2 for 10 seconds, electromagnetic relay X1 for 180 seconds, both electromagnetic relays X1 and X2 for 10 seconds, electromagnetic relay X2 for 180 seconds, both electromagnetic relays X1 and X2 for 300 seconds In this way, the rotation shaft 3b provided with the stirring rods 3c, 3c, and 3c is caused to repeat the same rotation and stop cycles. (Not disadvantageous in other rotation or stop of the cycle).

  It should be noted that when the lid 1b is opened for the input of garbage, etc., and the electric motor 3e is driven to rotate at that time, that is, either the electromagnetic relay X1 or X2 is closed. If so, the electromagnetic relay X1 or X2 is immediately opened, and the rotation operation of the electric motor 3e is stopped so as to ensure safety. The opening and closing of the lid 1b is detected by a sensor (not shown), and the result is input to the control unit 7.

  In addition, an overload is applied to the electric motor 3e that drives the rotary stirring means 3, and the output voltage drop of the tachometer generator 11 due to the reduction in the rotation speed is detected by the voltage detector 8, and an output to that effect is output. In this case, immediately, the electromagnetic relay X1 or X2 that was closed at that time is opened, and control is performed to stop the rotation of the electric motor 3e. Then, after the open state of both electromagnetic relays X1 and X2 is continued for about 10 seconds, the other electromagnetic relay is used to rotate the electric motor 3e in the opposite direction to the rotation direction immediately before the stop for about 10 seconds. Control to close X1 or X2. In this embodiment, the closing of the other electromagnetic relay X1 or X2 is continued for about 4 seconds, and the rotary stirring means 3 is controlled to rotate in the reverse direction by about 1/8 rotation. In this way, it is intended to facilitate removal of foreign matters that may be caught between the rotary stirring means 3 and the garbage processing tank 2 or the like.

  Further, the exhaust means 4b of the exhaust cylinder 4 operates its electric motor in principle in conjunction with the electric motor 3e of the rotary stirring means 3, and performs an exhaust operation in conjunction with the stirring operation of the rotary stirring means 3. To control. However, the electric motor of the exhaust means 4b is always operated when the lid 1b is opened, and is controlled so that the exhaust operation is always performed while the lid 1b is opened. The odor is prevented from rising from the upper opening of the treatment tank 2.

  The heating means 6 is controlled so as to keep the inside of the garbage processing tank 2 at around 50 ° C. The reason why the control temperature is set to about 50 ° C. is that if the inside of the garbage treatment tank 2 is heated to around the above temperature, various germs, roundworm eggs, and worms contained in the garbage It is known that insect eggs, cocoon eggs, and the like can be killed or inactivated, and it is possible to previously remove various harmful effects caused by rot of raw garbage caused by these germs and adult roundworms. Therefore, it goes without saying that the microorganisms used for the decomposition of the garbage here should be those that do not die or become inactivated at such temperatures.

  Therefore, according to the extinguishable garbage processing machine of this embodiment, a failure such as the rotation stops due to foreign matter caught between the rotating stirring means 3 and the bottom of the garbage processing tank 2 or the like. When this occurs, the rotational speed of the tacho generator 11 decreases in conjunction with this, and the output voltage decreases. This decrease in output voltage is detected by the voltage detector 8 and is as described above. In addition, after the stop of the supply of driving power for the electric motor 3e and the elapse of the predetermined stop time, power is supplied for rotation at a predetermined rotation angle in the reverse direction, thereby removing the foreign matter. It can be easily removed, and can be accurately implemented with a simple configuration.

  The occurrence of such an abnormal situation is notified by the blinking lighting operation of the light emitting diode 9d of the abnormality notification lamp circuit 9, and this situation is notified to the user and other related parties. Thus, the user or the like can easily know such a situation, and can open the lid 1b and inspect the inside to remove the foreign matter. Thereafter, when the control unit 7 and the abnormality notification lamp circuit 9 are reset by operating a predetermined reset switch, the light emitting diode 9d is turned off, and the normal operation control state by the control unit 7 is recovered.

  During the operation of the extinguishable garbage processing machine of this embodiment, when a piece of wood (5 cm × 10 cm × 30 cm) was put into the garbage processing tank 2, the light emitting diode 9d flashed immediately, It was informed that the piece of wood became an obstacle to the rotation of the rotary stirring means 3. When the lid 1b is opened after waiting for about 20 seconds and the inside of the garbage disposal tank 2 is looked into, the wood piece is located at the bottom, but the stirring bar 3c of the rotary stirring means 3 has already been in contact with the wood piece. There was a slight gap between them. This is because it is detected that the piece of wood is sandwiched between the bottom of the garbage disposal tank 2 and prevents the rotation stirring means 3 from rotating, and after the rotation is temporarily stopped, the rotation stirring is performed as described above. This is probably because a slight reverse rotation of the means 3 was performed, and as a result, there was a slight gap between the means 3 and the stirring bar 3c. Therefore, the piece of wood could be easily taken out from the bottom of the garbage disposal tank 2. Thereafter, when the lid 1b was closed and the reset switch was operated, the light emitting diode 9d was extinguished, and the extinguishable garbage processing machine resumed normal operation.

Further, according to the extinguishable garbage processing machine of this example, not only the above-described excellent recovery processing of the abnormal state but also the normal processing was performed as follows.
The raw garbage treatment tank 2 is loaded with a base material composed of porous wood chips mixed with microorganisms in advance. Then, a main switch (not shown) is turned on to control the controller 7, that is, an electric motor 3 e that drives the rotary stirring means 3, an exhaust means 4 b of the exhaust cylinder 4 in the intake and exhaust means, and The control operation or the like for the heating means 6 is started.

  Then, the garbage thrown into the garbage treatment tank 2 is well mixed with the base material by the rotating stirring means 3 that repeats forward rotation and reverse rotation at predetermined time intervals as described above. At the same time, the gas phase conditions are improved, and the internal temperature conditions are also maintained well by the heating means 6, so that the activity of microorganisms becomes active, and the input raw garbage Is satisfactorily oxidatively decomposed. Further, the water and carbon dioxide thus decomposed and generated are exhausted through the exhaust cylinder 4, and at this time, solid components such as dust are removed by the filter 4a, and the off-flavor components that may be generated are It is removed by the odor adsorbing portion 4c, and does not cause a problem that dust or a strange odor is scattered in the surrounding environment.
