It is characterized in that the processing operation is stopped when a predetermined time elapses without exceeding the humidity.

  In the garbage processing apparatus according to claim 1, while the garbage (organic waste) in the treatment tank is agitated and mixed with the ore-based decomposition catalyst by the stirrer, hot air is sequentially supplied into the treatment tank and discharged sequentially. Is done. As a result, the garbage reacts with the decomposition catalyst to be reduced in volume, and the moisture is converted into steam by the hot air and is discharged by the exhaust means. The degree of volume reduction in the treatment tank can be estimated from the degree of decrease when the humidity in the treatment tank once increases and decreases. According to the first aspect of the present invention, when the humidity in the processing tank is detected by the humidity sensor and the detected humidity becomes equal to or lower than the set humidity, it is possible to appropriately detect the completion of the processing. And since a control means alert | reports the meaning of a process driving | operation completion to a notification device, a process completion notification can be performed immediately after completion | finish of a process driving | operation.

  In the garbage processing apparatus according to claim 3, the control means further keeps the humidity detected by the humidity sensor from becoming higher than another set humidity from the time when the humidity detected by the humidity sensor becomes lower than the set humidity. Since the processing operation is stopped when the predetermined time has elapsed, it is possible to prevent the processing operation from being continued without starting to throw in garbage or passing the operation stop. That is, when the processing completion notification is given, the worker usually recognizes this and throws in the next garbage, or when there is no garbage, the power switch is turned off to stop the processing operation. When the notification is not noticed, there is a concern that the processing operation continues. However, according to the third aspect, it is possible to prevent the processing operation from being continued without starting to throw in the garbage or without stopping the operation.

In the garbage processing apparatus of Claim 4, since the said hot air supply means supplies a hot air along the rotation direction of the said stirring body, the contact time of a hot air with respect to the accommodation currently stirred in the processing tank Becomes longer, and the volume reduction processing speed becomes faster.
In the garbage processing apparatus according to claim 5, the hot air emitted from the hot air discharge port of the hot air supply means is against a portion where the agitator lifts and drops the contents of the treatment tank, that is, a portion where the contents are scattered. Since it is supplied in the falling direction, the contents and hot air are mixed well, and the volume reduction processing speed is further increased.

  In the garbage processing apparatus according to claim 6, the rotating shaft of the stirring body is provided so as to be shifted in a direction away from the hot air discharge port with respect to the arc center of the arc-shaped bottom portion. In this case, the dispersion of the contents in the container is moderately dispersed, the permeability of the hot air is improved, and the volume reduction processing speed is further increased.

  In the garbage processing system according to claim 7, when the humidity detected by the humidity sensor is equal to or lower than a set humidity, the fixed amount supply means causes the garbage processing device to supply a certain amount of garbage. When the processing is completed, the garbage can be automatically loaded, and the garbage can be automatically loaded and processed sequentially.

  In the garbage processing system according to claim 8, when the humidity detected by the humidity sensor in the garbage processing apparatus becomes equal to or lower than a set humidity, the contents in the processing tank are moved to the sorting means by the contents unloading means. Since the stored material is separated by the separating means and the sorted stored material having a particle size less than a predetermined particle size is transported to the treatment tank by the transporting means, foreign substances are automatically removed from the used decomposition catalyst. Can be automatically reused. That is, the powder cracking catalyst is separated as a container having a particle size smaller than a predetermined particle size, and the container other than the powder cracking catalyst (a green plastic sheet for cracking, slicing or sashimi, a small plastic container containing soy sauce or sauce) Since it becomes a predetermined particle size or more, it is automatically sorted as foreign matter by the sorting means. And since the decomposition catalyst which removed the stored material, ie, a foreign material, less than the said predetermined particle size automatically is carried in to a processing tank, a foreign material can be automatically processed from the used decomposition catalyst, and can be automatically reused.

  In the garbage processing system according to claim 9, the control means further determines the humidity detected by the humidity sensor from the time when the humidity detected by the humidity sensor becomes equal to or lower than a set humidity, while the humidity detected by the humidity sensor does not become higher than another set humidity.

The garbage disposal apparatus 1 includes a processing tank 3, a hot air supply device 4 as a hot air supply unit, a stirring motor 5, and the like in an outer casing 2, and an operation unit 6 and a display unit as a notification unit outside the outer casing 2. 7 is provided.

  The processing tank 3 has a rectangular planar shape, and the bottom plate portion 3a has an arcuate surface with the virtual horizontal axis P as the center. Further, the rear vertical plate portion 3b connected to the rear portion of the bottom plate portion 3a and the vertical rear surface plate portion 3c are shifted forward and backward, and a horizontally long hot air discharge port 8 is formed between the two. A charging duct 9 having a substantially square planar shape is formed on the upper portion of the processing tank 3. A lid 10 that is opened and closed by the user is rotatably provided at the upper opening of the charging duct 9 by a hinge 10a, and the closed state is locked by a lock member 10b.

Note that the size of the treatment tank 3 may be changed according to the amount of garbage processed.
Inside the processing tank 3, a rotating shaft 12 of the stirring body 11 is rotatably provided by bearings 13 and 14 around a virtual horizontal axis Q that is spaced forward by a predetermined distance A with respect to the virtual horizontal axis P. . That is, the rotating shaft 12 of the stirrer 11 is provided so as to be shifted in a direction away from the hot air outlet with respect to the arc center P of the arc-shaped bottom plate portion 3a.

  The stirring body 11 is configured by attaching five pairs of blades 15 in the axial direction to the rotating shaft 12 in a set. The rotation trajectory of the outermost end of the blade 15 is indicated by reference numeral 15k. In these five sets of blades 15, the blade attachment angles of the adjacent blades 15 in the axial direction are shifted by a half pitch (90 degrees).

  The stirring motor 5 is disposed at the rear part of the processing tank 3 and rotates the stirring body 11 via a transmission mechanism 16. The belt transmission mechanism 16 includes a sprocket 16a attached to the rotating shaft of the agitating motor 5, a sprocket 16b attached to a protruding portion of the rotating shaft 12 protruding from the processing tank 3, and both sprockets 16a. , 16b and a chain 16c erected on 16b. The agitator 11 is rotated in the direction of arrow B.

  The hot air supply device 4 includes a hot air generator 17, a supply duct 18, and a hot air expansion duct 19 disposed at the rear part of the processing tank 3. The hot air generator 17 includes a blower (having a blower motor and a blower fan) (not shown) and a heater in the outer case 17a, and the hot air generated here is the supply duct 18 and the hot air expansion duct. 19 is supplied downward from the hot air outlet 8 into the processing tank 3.

  Exhaust ducts 20 and 21 are connected to the left and right side plate portions of the input duct 9 of the treatment tank 3 as exhaust means, and these exhaust ducts 20 and 21 are also connected to a common exhaust duct 22 as exhaust means. Connected and communicates with the outside. A deodorizing filter 23 is attached to the discharge end of the common exhaust duct 22.

Further, a humidity sensor 24 is attached inside the common exhaust duct 22.
The operation unit 6 includes a power switch 6a, a stirring motor on / off switch 6b, a blower motor on / off switch 6c of the hot air supply device 4, and a heater on / off switch 6d of the device 4. In this case, the agitation motor 5 is driven to rotate when the agitation motor on / off switch 6b is turned on after the power switch 6a is turned on. In conjunction with turning on the stirring motor on / off switch 6b, the blower motor on / off switch 6c of the hot air supply device 4 and the heater on / off switch 6d of the device 4 are also turned on. The switches 6a to 6d can be manually turned off.

  Further, the display unit 7 is provided with a green indicator lamp 25 and a red indicator lamp 26 as notification means, and the green indicator lamp 25 is a green light emitter (notifier) for notifying that processing is complete and garbage can be put in. For example, the red indicator lamp 26 is composed of a red light emitter for notifying that garbage cannot be thrown in and that the processing is being executed.

  Further, a control device 27 as a control means is provided on the inner surface of the back plate 2a of the outer casing 2. The control device 27 controls the entire operation of the garbage disposal device 1, and includes the agitation motor 5, a blower motor (not shown), and a relay switch for a heater.

  The control device 27 operates as follows. When a proper amount of the decomposition catalyst 28 is accommodated in the treatment tank 3, garbage (organic waste) is put in, the power switch 6a is turned on, and then the stirring motor on / off switch 6b is turned on. The switch energizes the agitation motor 5 and the blower motor to rotate it, and the heater is also energized. Further, the green indicator lamp 25 is turned on. This first green lighting indicates that additional garbage can be thrown in.

The cracking catalyst 28 is made of ore-based powder containing feldspar and phosphorus ore, and has a particle size of less than 5 mm, for example.
The stirring body 11 is rotated by the rotation of the stirring motor 5, and the hot air supply device 4 generates hot air (above 40 ° C. to 150 ° C. or less) and supplies it into the treatment tank 3. Since the hot air is supplied from the hot air discharge port 8 along the rotation direction of the agitator 11 (see arrow C in FIG. 5), the hot air is heated against the contents stirred in the treatment tank 3. The contact time becomes longer and the volume reduction processing speed becomes faster. In addition, since the hot air is supplied in the direction in which the agitator 11 lifts and drops the contents of the treatment tank 3, that is, the portion where the contents are separated, the contents and the hot air are mixed well. Furthermore, the volume reduction processing speed becomes faster.

  At this time, the rotating shaft 12 of the stirrer 11 is provided so as to be shifted in the direction away from the hot air outlet 8 with respect to the arc center P of the arc-shaped bottom (bottom plate portion 3a). The dispersion of the contents in the 8 parts is moderately dispersed, the permeability of hot air is improved, and the volume reduction processing speed is further increased.

  By the rotation of the agitator 11, the garbage (organic waste) in the treatment tank 3 is agitated and mixed together with the ore-based decomposition catalyst 28, hot air is sequentially supplied into the treatment tank 3 by the hot air supply device 4, and exhausted sequentially. It is discharged from the ducts 20-22.

As a result, the garbage reacts actively with the ore-based decomposition catalyst 28 and gradually reduces to water in 5 to 15 minutes, and the moisture becomes steam by the hot air and is exhausted.
The control device 27 monitors the humidity in the processing tank 3 and performs processing even after a predetermined time (for example, 10 minutes, which can be changed) has elapsed after the first power switch 6a is turned on and after the processing is completed. When the humidity in the tank 3 (the humidity detected by the humidity sensor 24) does not reach the first set humidity k1 (another set humidity), the power switch 6a is turned off (the power is turned off, that is, the processing operation is stopped). Yes. In other words, since there is no increase in humidity in the treatment tank 3 when there is no input of garbage, this is detected as a so-called color operation, and the treatment operation is stopped.

  If the detected humidity becomes equal to or higher than the first humidity k1 before the predetermined time elapses (when garbage is thrown in and processing proceeds), the green indicator lamp 25 is turned off and the red indicator lamp 26 is turned on. Turns on and displays (notifies) the meaning that garbage cannot be added.

And it agitates, mixing with the thing (catalyst and garbage) and hot air of the processing tank 3 by continuous supply of stirring and a hot air, and a volume reduction process advances.
Thereafter, the detected humidity further increases, but the control device 27 determines whether or not the detected humidity is equal to or lower than the second set humidity k2 (set humidity), and the second set humidity k2 When it becomes below, it will detect that the inside of the processing tank 3 was in a dry state (process completion state), and the red display lamp 26 is turned off and the green display lamp 25 is turned on. When the green indicator lamp 25 is turned on, it is displayed that the volume reduction processing is completed and the garbage can be put in. In the treatment tank 3, most of the garbage is treated and the decomposition catalyst 28 remains, so that it can be reprocessed.

  When the operator recognizes the completion of the processing by this notification (lighting of the green display lamp 25) and then newly throws in garbage, the volume reduction processing is performed again. The lighting state of the green indicator lamp 25 continues (in this period, garbage can be thrown in). At this time, if the predetermined time elapses before the first set humidity k1 is not exceeded, the processing operation is stopped as described above. If the first set humidity k1 or more is reached before the predetermined time elapses, the green indicator lamp 25 is turned off and the red indicator lamp 26 is turned on as described above to indicate that garbage cannot be added. (Notify).

By repeating such volume reduction processing, garbage is sequentially added and volume reduction processing is performed.
According to the present embodiment, hot air is sequentially supplied into the processing tank 3 while the garbage (organic waste) in the processing tank 3 is stirred and mixed with the ore-based decomposition catalyst 28 by the stirring body 11. Therefore, the garbage reacts actively with the decomposition catalyst 28 to become water, and the moisture is discharged as steam by the hot air, thereby promoting the volume reduction treatment. Such volume reduction treatment can significantly shorten the treatment time compared to volume reduction treatment using bacteria.

Incidentally, the volume reduction treatment using bacteria has the following problems.
Basically, this is a phenomenon in which the processing objects are gradually reduced by the bacteria eating the processing objects, and therefore a certain amount of time is required. It is impossible to significantly reduce the processing time artificially.

Bacteria are organisms, so they are vulnerable to low and high temperatures. The optimum temperature is about 30 ° C. to 40 ° C., and all of them die if they exceed the low and high temperature limit points.
Furthermore, if the same kind of treatment object is continuously added, the bacteria get tired of eating, so that a rejection reaction is caused for the treatment object and a long processing time is required. It is necessary to give food (process target) in a well-balanced manner, which is very troublesome.
Moreover, when discharged from the reaction tank, even if it is a safe bacterium, it remains a bacterium, so anxiety cannot be wiped out.
Furthermore, it is difficult to manage bacteria that are invisible creatures.

Moreover, since it is a fermentation process, a rotting odor is always generated.
On the other hand, when the ore-based decomposition catalyst 28 is used as in this embodiment, the processing time can be extremely shortened according to experiments. That is, according to the experiment of the present inventor, when garbage is treated using bacteria, it takes about 24 hours to complete the treatment, but using the ore-based decomposition catalyst 28 as in this embodiment. Processing takes about 10 minutes.

  Furthermore, in this embodiment, hot air is introduced into the treatment tank 3 and dried in order to efficiently perform the treatment. However, in the treatment using bacteria, since the bacteria are killed by the hot air, high temperature hot air cannot be introduced.

Furthermore, according to this embodiment, the same kind of processing object can be processed continuously for a long period of time.
Also, since no bacteria are used, temperature control is not necessary and it is safe. By the way, as a result of conducting a dissolution test and a component inclusion test, both conform to safety standards (see FIG. 6). Moreover, since it is not a fermentation process, no rot odor occurs.

  Furthermore, according to the present embodiment, the humidity in the treatment tank 3 is detected by the humidity sensor 24, and when the detected humidity is equal to or lower than the second set humidity k2, it is possible to properly detect the completion of the treatment. it can. Since the green indicator lamp 25 is notified of the purpose of completion of the processing operation, the processing completion notification can be performed immediately after the completion of the processing operation. As a result, it is possible to quickly start the next garbage disposal, and hence the next garbage disposal.

  Further, according to the present embodiment, from the time when the humidity detected by the humidity sensor 24 becomes equal to or lower than the second set humidity k2, the humidity detected by the humidity sensor 24 is equal to or higher than the first set humidity k1, which is another set humidity. Since the processing operation is stopped when a predetermined time elapses without becoming, the following effect can be obtained.

  That is, even if the worker is busy with other work and the green indicator lamp 25 is lit (processing is completed), even if the garbage cannot be thrown into the garbage processing apparatus 1, the processing is performed after a predetermined time. Since the operation is stopped, useless operation and use of electricity can be saved. Further, even when the worker goes to another site while operating the present garbage disposal apparatus 1, or when the worker returns home without turning off the power switch 6a, the operation can be automatically stopped. However, if the garbage is input, this processing operation does not stop.

Further, if the treatment operation is continued without throwing in the garbage, the catalyst exceeds the limit due to hot air and is dried too much, so that the catalyst powder flies into the treatment tank 3 and rides on the hot air to the exhaust duct 20. Although there exists a possibility of passing through ~ 22 and going outside, in this embodiment, this can also be prevented.
Moreover, according to this embodiment, since hot air is supplied along the rotation direction of the stirring body 11, the contact time of hot air with respect to the agitated thing in the processing tank 3 becomes long, and volume reduction processing is carried out. Increases speed.

  Furthermore, according to the present embodiment, the hot air is supplied in a direction in which the agitator 11 lifts and drops the contents of the treatment tank 3, that is, the part where the contents are separated. Are mixed well, and the volume reduction processing speed is further increased.

  Furthermore, according to the present embodiment, the rotating shaft 12 of the stirrer 11 is provided so as to be shifted in the direction away from the hot air discharge port 8 with respect to the arc center of the arc-shaped bottom plate portion 3a. Dispersion of the contents at the outlet 8 portion is moderately dispersed, the permeability of hot air is improved, and the volume reduction processing speed is further increased.

  7 and 8 show a second embodiment of the present invention, and the garbage processing system 30 of this embodiment is configured so that the garbage can be automatically input. The garbage processing system 30 has a configuration in which a fixed amount supply device 31 is provided as a fixed amount supply means for supplying a fixed amount of garbage to the garbage processing device 1. A different part from the said 1st Embodiment is demonstrated. The fixed amount supply device 31 includes a fixed amount hopper 32, a fixed amount delivery device 35, a belt conveyor 37, and a garbage storage hopper 38.

  And the processing tank 3 does not have the lid | cover 10, The said fixed quantity hopper 32 is provided in the said processing tank 3 upper part. The fixed hopper 32 includes a duct-like hopper main body 32a whose upper and lower surfaces are open, and a damper 32b that is opened and closed by a driving source (not shown). The metering hopper 32 communicates with the processing tank 3 via a bellows 34. The fixed quantity hopper 32 is supported by the outer casing 2 of the garbage processing apparatus 1 by a spring 36. In the fixed quantity hopper 32, the input amount of the garbage reaches a predetermined weight by a weight measuring means (not shown). When the quantity is detected, the delivery operation of the constant quantity delivery device 35 and the belt conveyor 37 is stopped (the garbage supply to the quantity hopper 32 itself is stopped), and the dumper 32b is rotated downward to process the garbage. It can be automatically charged into the tank 3.

  A fixed amount of garbage is supplied from the fixed amount delivery device 35 via the belt conveyor 37 to the upper surface inlet of the fixed amount hopper 32 in a unit time. The fixed amount delivery device 35 carries the garbage in the garbage storage hopper 38 onto the belt conveyor 36 in a fixed amount per unit time. In this way, the garbage processing apparatus 1 is continuously operated continuously, and a certain amount of garbage is input every time the processing is completed.

  In the second embodiment, the control device 27 controls as follows. The control device 27 monitors the weight detection result by the weight measuring means, and when the garbage processing device 1 is in a processing operation, a fixed amount (predetermined weight) of garbage is accommodated in the fixed quantity hopper 32, The weight measuring means detects the predetermined weight, stops the delivery operation of the fixed quantity delivery device 35, rotates the damper 32b downward, and automatically throws the garbage into the processing tank 3, thereby making the garbage Is automatically put into the processing tank 3, and the damper 32b is returned to the original position after a set time (for example, after 10 seconds, this can be changed). After the damper 32b is returned to the original position, the delivery operation of the quantitative supply device 35 is activated to supply the garbage into the quantitative hopper 32. In this way, volume reduction processing is performed in the garbage processing apparatus 1. When the humidity sensor 24 detects the first set humidity k1, the green display lamp 25 is turned off and the red display lamp 26 is turned on.

  When the volume reduction process proceeds and the humidity in the processing tank 3 is equal to or higher than the second set humidity k2, the red indicator lamp 26 is turned off and the green indicator lamp 25 is turned on, and again in the fixed quantity hopper 32. The fixed amount of garbage that has been carried in is automatically carried into the garbage disposal apparatus 1. This process is repeated to sequentially perform garbage disposal. In this case as well, the processing operation is stopped when a predetermined time elapses without detecting the first set humidity k1.

According to the second embodiment, when the humidity detected by the humidity sensor 24 becomes equal to or lower than the second set humidity k2, the fixed amount supply device 31 allows the fixed amount supply device 31 to supply a fixed amount of food waste. Each time the processing is completed in the garbage processing apparatus 1, the garbage can be automatically charged, and the automatic garbage charging and automatic processing can be sequentially performed.
In this embodiment, the quantitative hopper 32 may not have a weight measurement function, and may be a simple hopper. In this case, a fixed amount of garbage may be sent out by the fixed amount sending device 35 and supplied to the hopper via the belt conveyor 37.

  9 to 11 show a third embodiment of the present invention. The garbage processing system 50 according to the third embodiment is configured to remove foreign substances from the stored items after the garbage processing is completed. That is, with respect to the garbage processing system 30 of the second embodiment, a sieve device 51 (sorting means) having a predetermined particle size and a container for carrying the contents in the processing tank 3 to the sieve apparatus 51. Carrying-out device 52 (contained material carrying-out means), carrying-in device 53 (carrying-in means) for carrying stored materials of less than a predetermined particle size separated from the sieving device 51 into the treatment tank 3, foreign matter disposal conveyor 54, foreign matter And a storage tank 55.

Further, the bottom plate portion 3a of the processing tank 3 is configured to be openable and closable and is opened and closed by a driving means (not shown).
The sieve device 51 is for separating the contents of the processing tank 3 into less than 5 mm and more than 5 mm, and includes a 5 mm sieve that can be vibrated by a drive source (not shown). In addition, the stored item carrying-out device 52 is constituted by a conveyor, and is arranged so as to reach the sieving device 51 from a lower part of the processing tank 3.

The carry-in device 53 for carrying in is made up of a screw conveyor, receives the contents separated as less than 5 mm, and throws them into the fixed amount hopper 32 of the processing tank 3.
Further, the foreign matter disposal conveyor 54 receives the contents separated by 5 mm or more and puts them in the foreign matter storage tank 55.

  In this embodiment, when the control device 27 detects that the humidity detected by the humidity sensor 24 is equal to or lower than the second set humidity k2 (when processing completion is detected), the sieving device 51 and the contents carrying-out device 52 are used. Then, the carry-in device 53 and the foreign matter disposal conveyor 54 are activated, and the bottom plate portion 3a is automatically opened, and the contents in the processing tank 3 are dropped onto the contents-delivery device 52. Then, after the set time (for example, after 10 seconds), the bottom plate portion 3a is closed. Here, the container is usually the decomposition catalyst 28 after the garbage treatment is completed, but a foreign material (green plastic sheet, soy sauce and sauce that is broken, sashimi or sashimi) is put together with the garbage. If a small plastic container is put in by mistake, these foreign substances also remain. This foreign material is 5 mm or more. Note that the sieve eyes can be changed to other than 5 mm in consideration of the size of the foreign matter. The upper limit of the hot air temperature is set to 150 ° C. so that the plastic foreign matter does not melt.

  This stored material is conveyed to the sieve device 51 by the stored material unloading device 52, and is separated into less than 5 mm (that is, the decomposition catalyst 28) and 5 mm or more (foreign material) by this sieve device 51, that is, the stored material of less than 5 mm, that is, The cracking catalyst 28 is put into the quantitative hopper 32 of the processing tank 3 by the carry-in device 53. After that, the fixed quantity hopper 32 is supplied with fixed quantity of garbage from the fixed quantity delivery device 35 through the belt conveyor 37 on the decomposition catalyst 28 in a unit time. When the fixed hopper 32 reaches a set weight (in this case, the weight including the cracking catalyst 28 and garbage), the belt conveyor 37 and the fixed amount supply device 52 are stopped, the damper 32b is opened, and the cracking catalyst 28 and the raw garbage are released. Garbage is put into the treatment tank 3.

  In this case, since the cracking catalyst 28 is located on the upper surface of the damper 32b and the garbage is located thereon, even if the garbage is viscous, the garbage adheres to the damper 32b when the damper 32b is opened. Therefore, the garbage can be thrown into the treatment tank 3 without any trouble.

Further, in this case, since the decomposition catalyst 28 is first introduced into the treatment tank 3, the garbage does not adhere to the inner surface of the treatment tank 3, and the stirring operation can be performed smoothly.
Alternatively, the decomposition catalyst 28 may be put into the treatment tank 3 first, and then the garbage is weighed and a fixed amount may be put in. The set weight can be changed depending on the model.

  The stored items (foreign matter) separated by 5 mm or more are stored in the foreign matter storage tank 55 by the foreign matter disposal conveyor 54. The foreign matter in the foreign matter storage tank 55 can be recycled by being separated into plastic, wood, metal, paper, and the like. In this way, while the garbage disposal apparatus 1 is continuously operating continuously, the decomposition catalyst 28 and the foreign matter in the treatment tank 3 are separated each time the treatment is completed, and the decomposition catalyst 28 from which the foreign matter has been removed is returned to the treatment tank 3, and , Repeat that a certain amount of garbage is thrown in.

  According to such 3rd Embodiment, when the humidity detected by the humidity sensor 24 in the garbage processing apparatus 1 becomes equal to or lower than the second set humidity k2, the contents in the processing tank 3 are transferred to the contents carrying out apparatus. It is used because it is carried out to the sieving device 51 by 52, and the contents are separated from the sieving device 51, and the sorted less than predetermined particle size is carried into the processing tank 3 by the carrying-in device 53. Foreign substances can be automatically removed from the cracking catalyst 28 and automatically reused. That is, the powder cracking catalyst 28 is separated as a container having a particle size smaller than a predetermined particle size, and the container other than the powder cracking catalyst 28 (a green plastic sheet for cracking, filling or sashimi, a small plastic container containing soy sauce or sauce, etc. ) Is equal to or greater than a predetermined particle size, and is automatically sorted as foreign matter by the sieving device 51. Then, since the decomposition catalyst 28 from which the contained particles, that is, foreign matters are removed automatically is carried into the treatment tank 3, foreign matters can be automatically processed from the used decomposition catalyst 28 and automatically reused.

  FIG. 12 shows a fourth embodiment of the present invention. The garbage processing device 61 of the fourth embodiment differs from the garbage processing device 1 of the first embodiment in the following points. That is, a hopper 62 that can automatically put garbage into the treatment tank 3 is provided. The hopper 62 includes a main body 62 whose upper and lower surfaces are open, and a damper 62b that opens and closes a lower opening of the main body 62a by a driving source (not shown). The capacity of the hopper 62 is preferably a capacity capable of storing garbage with a processing capacity of one time. Then, when the humidity detected by the humidity sensor 24 becomes equal to or lower than the second set humidity k2, the control device 27 operates the damper 62b of the hopper 62 to put garbage into the treatment tank 3, and then When a predetermined time (for example, 10 seconds) elapses, the original position is restored.

  In this embodiment, when the humidity in the processing tank 3 is detected by the humidity sensor 24 and the detected humidity becomes equal to or lower than the second set humidity k2, it is possible to properly detect the completion of the processing. . Since the control device 27 operates the damper 62b of the hopper 62 when the humidity detected by the humidity sensor 24 is equal to or lower than the second set humidity k2, the garbage is put into the processing tank 3 in advance. If the garbage is put in the hopper 62, the garbage can be put in immediately and automatically after the processing is completed, and the convenience is improved. That is, it is convenient for the operator to watch the time and put the garbage into the hopper 62. In the case of this embodiment, the indicator lights 25 and 26 may be provided as necessary.
