At the time of transferring the processed material from the first tank 11a to the second tank 11b, the processed material D is rotationally driven in a direction of scraping the processed material D toward the transfer port 12a by the stirring blades 70a to 70d as shown in FIGS. ), At the time of discharging the processed material and during the above-mentioned normal operation, as shown in FIGS. 15 and 16, in the second tank 11b, the stirring blade 70e is used to scrape the processed material D toward the discharge port 13a, and In the tank 11a, the stirring blades 70a to 70d rotationally drive the processed product D in a direction away from the transfer port 12a (normal rotation).

Generally, stirring blades of this kind are provided on the stirring shaft at equal intervals, but in this embodiment,
In order to improve the transfer efficiency of the processed material in the first tank 11a to the second tank 11b, the step intervals are narrowed toward the transfer port 12a (in FIG. 15, A>B> C).
Will be).

The stirring blades 70a to 70a of the first tank 11a are also included.
0d is erected on the stirring shaft 71 in a spiral shape. This twist direction is the same as the workpiece D during normal operation and during normal rotation during discharge.
Moves to the opposite side (back side) from the transfer port 12a, and the first tank 1
It is in such a direction that the processed material D moves to the transfer port 12a side at the time of reverse rotation of transferring from 1a to the second tank 11b.

Now, in the above configuration, a fixed amount of the microbial carrier is previously charged into the first tank 11a of the processing tank 11 at the start of use of the present apparatus. When processing garbage, the upper lid 15 is opened and the processing tank 11 is opened from the input port 14.

By controlling the energization of the agitating motor 75, the agitating shaft 71 on which a plurality of agitating blades 70a to 70e are erected is intermittently rotated forward to agitate the carrier and food waste put in the first tank 11a. Mix. At the time of this normal rotation, as described above, the stirring blades 70a to 70d rotate in the direction (clockwise direction) shown by the arrow in FIG. 16, so that the treated product D in the first tank 11a in which the carrier and the garbage are stirred and mixed. Is in a direction away from the transfer port 12a as shown in FIG. 15 and FIG. 15, the unprocessed processed material D is not transferred to the second tank 11b.

Further, by controlling the energization of the exhaust fan 60, air (exhaust gas) containing water vapor and malodor in the processing tank 11 is passed through the exhaust port 17 and the double bottom portion 11d of the processing tank 11 to form a flexible duct 19. , Deodorizing mechanism 40, processing tank 1

Fresh outside air is taken in through the flexible duct 44 passing through the double bottom 11d of No. 1 to supply the oxygen necessary for activating the microorganisms into the treatment tank 11.

Further, by controlling the energization of the heater 20 of the deodorizing mechanism 40, the exhaust gas discharged from the exhaust port 17 as described above is heated to a catalytic reaction temperature of about 300 ° C. or higher and supplied to the catalyst 30. The high-temperature exhaust gas supplied into the catalyst 30 heats the catalyst 30 to the same temperature, and is deodorized by the oxidative decomposition reaction of the malodor promoted by the catalyst action, and while passing through the catalyst 30, Completely deodorized. The odorless high-temperature exhaust gas is introduced into the double bottom portion 11d of the processing tank 11 while maintaining the temperature around 250 ° C., and the flexible duct 44 that allows the outside air supplied to the processing tank 11 to pass therethrough.
The flexible duct 19 for passing the exhaust gas supplied to the deodorizing mechanism 40 is heated, and then discharged to the outside via the fan 60 provided on the upper rear side of the main body case 10.

As described above, since the flexible duct 44 for passing the outside air supplied to the processing tank 11 is passed through the double bottom portion 11d of the processing tank 11, the deodorizing mechanism heated by controlling the energization of the heater 20 described above. The high temperature exhaust gas from 40 and the outside air exchange heat (primary preheat), and the outside air warmed to about 60 ° C. is supplied into the processing tank 11. Further, since the flexible duct 19 for passing the exhaust gas supplied to the deodorizing mechanism 40 is also passed through the double bottom portion 11d of the processing tank 11, the high temperature exhaust gas from the deodorizing mechanism 40 heated by the energization control of the heater 20 is performed. The gas and the exhaust gas exchange heat (secondary preheating), and the exhaust gas warmed to about 150 ° C. is supplied into the deodorizing mechanism 40.

As described above, since the air entering the heater 20 of the deodorizing mechanism 40 is preheated in two stages, the temperature rise by the heater 20 is designed to be about 300 ° C. to about 150 ° C.
= Can be suppressed to about 150 ° C, the conventional level of about 300 ° C
Since about 90 ° C. is less than about 60 ° C. = about 240 ° C., the energization rate of the heater 20 can be reduced correspondingly, the electricity bill can be reduced, and the running cost can be kept low.

By controlling as described above, the temperature in the entire treatment tank 11 is in the optimum range (about 6) for activating the microorganisms.
Fermentation is carried out while maintaining the temperature at around 0 ° C., and the garbage is decomposed into carbon dioxide and water by the microorganisms cultivated on the carrier to be composted.

When the above-mentioned processing is performed for, for example, 18 hours or more and the composting of the processed material D is almost completed, the control section drives the stirring motor 75 in the reverse rotation. At the time of this reverse rotation, as described above, the stirring blades 70a to 70d in the first tank 11a rotate in the direction (counterclockwise direction) shown by the arrow in FIG. 19, so that the processed material D composted in the first tank 11a is processed. Is scraped up toward the transfer port 12a as shown in FIG.

During this normal rotation, the stirring blades 70a to 70e rotate as shown in FIG. 16 as in the above-described normal operation, so that the processed material D transferred to the second tank 11b is discharged from the discharge port 13a.
And is efficiently taken out to the outside from the discharge port 13a. The treated product D taken out can be effectively used as an organic fertilizer. Since the processed product D in the first tank 11a at the time of discharge is away from the transfer port 12a as shown in FIG. 15 as in the above-described normal operation, the unprocessed processed product D is in the second tank. It is not transferred to 11b.
