At this time, when the garbage is to be introduced for the first time, auxiliary materials (for example, sawdust, zeolite, and perlite) to which aerobic bacteria are attached as seeds are introduced together with the garbage to remove the garbage. The fermentation is promoted, and the garbage to be crushed and stirred is prevented from being crushed and liquefied, and is made as porous as possible.

Thereafter, the fermented product partially staying in the fermentation tank 32 serves as a fermentation promoting function instead of the auxiliary material, and the garbage is produced for a certain period of time, for example, one month. The garbage is accumulated in the garbage treatment tank 32, fermented, and then aged to be collected as a final residue.

Then, as shown in FIG. 17, the first processing object processed in the first processing tank 32 causes each of the stirring claws 41, 42, 43, and 44 to move clockwise in a side view by a stirring driving motor 50. The first processing object B, which is scooped up by the second stirring claw 42, can be caused to overflow into the second processing tank 33 through the first overflow window 34.

At this time, a first processing object B which overflows is recovered through the second overflow window 35 by providing a height difference of a fixed height H between the first overflow window 34 and the second overflow window 35. The short path collected by the section 3 can be prevented.

The first processed material transferred into the second processing tank 33 is further fermented and aged while being stirred by the fourth stirring claws 44. Therefore, fibrous plants that are not easily fermented in the second processing tank 33 can be fermented and matured without fail.

At this time, in the second processing tank 33, the second processed material is transferred to the second overflow window by the fourth stirring claw 44 rotating forward.
Through 35, it is possible to overflow into the collecting section 3.

The deodorizing unit case 67 is formed of a case main body 67a formed in a horizontally long box shape with a rear opening, and a lid 67b detachably attached to the rear end surface of the case main body 67.

In the case body 67a, a catalyst housing case 67c is arranged at the center, and the catalyst 69 is installed in the catalyst housing case 67c.
The catalyst 69 is partitioned to form a deodorizing space 70 and an exhaust space 71, and an ozone generator as a deodorizer 65 is mounted above the side wall 67d on the deodorizing space 70 side. Near the bottom of the case body 67a.
Standing up to the vicinity of the ceiling wall 67g, the channel forming wall 67d
An outside air intake hole 72 is formed in the lower part of the front wall of the case body 67a located between the outside air intake hole 72, the case body 67a, and the flow path forming wall 67e. Further, a dust collecting portion 67h is formed by the flow path forming wall 67e, the catalyst housing case 67c, and the bottom portion 67f.

An exhaust fan 66 driven by an exhaust fan driving motor 81 is arranged in the exhaust space 71, and an exhaust port 67j is formed in a lid 67b facing the exhaust fan 66.

The odor guide duct 68 has a base end 68a communicating with an exhaust window 73 opened on the rear wall 30d of the garbage disposal tank 30, extending the tip 68b directly downward, and disconnecting it. The area is gradually reduced, and a tip 68b is connected to the ceiling wall 67g of the deodorizing section case 67 so as to communicate with it.
And the communication. Reference numeral 73a denotes a net extending over the exhaust window 73.

Further, the cross-sectional area of the deodorizing space 70 is formed to be larger than the cross-sectional area of the front end 68b of the odor guide duct 68, and the dust pool 67h is disposed immediately below the front end 68b.

The catalyst 69 is one that reduces ozone to oxygen and removes remaining odorous substances.

As described above, by rotating the exhaust fan 66 to discharge the air in the deodorizing unit case 67, the odor generated in the garbage disposal tank 30 is removed from the exhaust window 73 → the odor guide duct 68 → Guide to the deodorizing space 70.

At this time, the odor flowing down in the odor guide duct 68 gradually increases the flow velocity, and the flow velocity is reduced as soon as it flows into the deodorizing chamber 70, while the external air inflow passage 72 a Outside air that has flowed into the deodorizing space 70 while taking in the ozone generated by the ozone generator on the way, and the odor and the outside air that has taken in the ozone are diffused and diluted in the deodorizing space 70 At the same time, the odor is deodorized by ozone, is further sucked into the exhaust space 71 through the catalyst 69, and is discharged outside through the exhaust space 71 → the exhaust port 67j → the exhaust hole 25.

The exhaust gas is exhausted from the deodorizing space 70 to the exhaust space.
Since the ozone is reduced into oxygen and flows into the exhaust space 71 through the catalyst 69 that removes the remaining odorous substances, the ozone does not flow into the exhaust space 71 and the ozone is discharged to the outside. It can be reliably prevented.

The dust that has flowed into the deodorizing space 70 together with the odor from the odor guiding duct 68 gently falls naturally in the deodorizing space 70 due to the slowing down and diffusion of the odor, and forms on the bottom 67f of the case body 67a. Dust accumulates in the accumulated dust part 67h.

Therefore, it is possible to reliably prevent the dust from being discharged to the outside together with the exhaust gas.

A proximity switch as a rear cover detection switch 99 is mounted below the side wall 67k on the exhaust space 71 side of the case body 67a, while a rear wall 10c as a rear cover facing the rear cover detection switch 99 is mounted. When the magnet 100 is attached to the lower part and the magnet 100 is close to the rear cover detection switch 99, the switch 99 keeps the switch OFF state,
When the switch 99 is turned on, the operation of the deodorizer 65 is stopped via the control unit 80.

Thus, for example, the deodorizing section case 67
When performing maintenance or the like of the catalyst 69 disposed therein, if the rear wall 10c as the rear cover is removed, the rear cover detection switch 99 is turned on and the operation of the deodorizer 65 can be stopped.

Therefore, by the time the lid 67b of the deodorizing section case 67 is removed, the ozone in the deodorizing space 70 is reduced, and it is possible to prevent the worker from inadvertently sucking ozone.

As shown in FIG. 18, the control unit 80 includes, on the input side, a closing lid open / close detection switch 15, a tray storage detection switch 16, a motor rotation sensor 75, a temperature sensor 76, a humidity sensor 77, While the discharge timing detection sensor 96b, the rear cover detection switch 99, the mode changeover switch 101, and the power switch 102 are connected, the heater 37, the stirring claw driving motor 50, the deodorizer 65, An exhaust fan drive motor 81, a power-on indicator lamp 82, a standard mode indicator lamp 83, a power-up mode indicator lamp 84, an exhaust indicator lamp 85, and an abnormality indicator lamp 86 are connected,

FIG. 25 shows a garbage disposal apparatus A as another embodiment. The garbage disposal apparatus A has the same basic structure as that of the garbage disposal apparatus A. A suction hole 110 is formed in the upper part of the front wall 30c of the processing tank 30, and a discharge hole 111 is formed in the rear wall 30d so as to face the suction hole 110. The lower end of the discharge guide duct 112 is bifurcated, and the lower end of the exhaust part 112a is bifurcated to form an exhaust part 112a and a circulation part 112b. The exhaust portion 112a is projected outward below the bottom portion 10d of the casing body 10, while the circulation portion 112b is bent forward along the bottom portion 10d to form an intake hole 113 at the front of the bottom portion 10d. Different.

In addition, an exhaust fan 114 is provided below the exhaust guide duct 112, and the circulating portion is larger than the cross-sectional area of the exhaust portion 112a.
The cross-sectional area of 112b is approximately twice as large.

When the exhaust fan 114 is operated in this way, the odor in the garbage disposal tank 30 is discharged from the exhaust hole 111 → the exhaust guide duct 112 → the exhaust section 112a → the flow path 115 for discharging to the outside.
And a circulation passage 116 for circulating in the exhaust hole 111 → the exhaust guide duct 112 → the circulation portion 112 b → the inside of the casing body 10 → the suction hole 110 → the garbage treatment tank 30. Air coming in from 113 merges.

At this time, since the cross-sectional area of the circulating portion 112b is approximately twice as large as that of the exhaust portion 112a, the amount of air circulated while taking in outside air is smaller than the amount of odor discharged to the outside. There are many.

As described above, by discharging the odor little by little, it is not necessary to deodorize or it is possible to deodorize with a small-scale deodorizer.

Furthermore, by taking in outside air during the circulation, oxygen required for the fermentation treatment can be taken in. By circulating the air heated in the garbage treatment tank 30, the temperature of the treated material can be prevented from lowering. it can.
