Next, the trolley 53 is traversed to move the empty container 1 on the trolley 53 to the garbage receiving position 41a, and the garbage inlet 5 with the lid 4 opened is a chute 52. Located just below the lower end of the. In such a state, garbage is thrown from the garbage truck 61 into the upper end side of the chute 52 projecting out of the warehouse, and the garbage is put into the container body 2 of the empty container 1 set in the garbage loading section 41. Supply within. In addition, at an appropriate time before or during the supply of the garbage, the soil, charcoal, and rice hulls are stored from the inoculum material storage 55 in accordance with the properties of the garbage to be supplied (type of material, moisture, etc.). The selected one type or several types are fed out by a required amount, and are fed into the chute 52 by the transport means 56 to supply the inoculum material into the container 1. When the garbage or the like is supplied, each of the stirring rotators 10a to 11b of the garbage stirring means 9 may be rotated by a motor 18 in a predetermined direction. Further, depending on the nature of the raw garbage supplied, water may be supplied.

In the situation where the container 1 is set in the garbage loading section 41 as described above, the container carrier 6
When the next empty container 1 is carried in by 0, the empty container 1 is moved over the ceiling to a position adjacent to the empty container carrying-in / out section 42 of the fermentation zone 43 as shown by a virtual line in FIG. It is also possible to temporarily put it temporarily using the crane 49.

The container 1 to which the raw garbage and the inoculum material are supplied in a predetermined amount in the raw garbage input section 41 is closed and then transferred to the fermentation zone 43 after the lid 4 of the raw garbage input port 5 is closed. That is, after the container 1 at the garbage receiving position 41a is moved to the temporary storage position 41b by the laterally moving cart 53 of the traverser 54, the container lifting action of the overhead traveling crane 49, traveling of the overhead traveling crane 49 to the fermentation zone 43,

After the transfer to the aging zone 44, the air supply unit 22 of the container 1 is stopped and the damper of the ventilation port 23 is closed to prevent abnormal drying in the refrigerator.

When a predetermined number of days (about two months) have passed within the aging zone 44 and the garbage in the container is ready for use as compost, the garbage is carried out of the container storage 40 together with the container 1. That is, the aging zone 4 is placed on the container carrier 62 that has entered the completed compost delivery vehicle entrance 46.
In this case, the completed compost storage container 1 in the overhead traveling crane 4 is transferred.
9, the lifting operation of the overhead traveling crane 49 on the container carrier 62 and the overhead traveling crane 4
9 is performed by the container unloading operation.

When the raw garbage in the container body 2 is completely fermented and aged to become compost, the amount of the compost is reduced by almost half. Therefore, the container 1 is temporarily transferred to the completed compost reloading zone 45 by the overhead traveling crane 49, and the next completed container 1 is moved to a position immediately above the container 1 with the lid 4 of the garbage input port 5 of the container 1 opened. The compost storage container 1 is transported from the aging zone 44 by the overhead traveling crane 49, and the container 1 suspended by the overhead traveling crane 49
The lid 7 of the completed compost take-out port 6 is opened, and the completed compost in the container main body 2 is transferred to the container 1 temporarily placed in the completed compost reloading zone 45, and the container 1 filled with the completed compost is transferred to the container 1 described above. Can be transferred onto the container carrier 62 as shown in FIG. The container 1 in which the completed compost remains remains can be dropped down to the completed compost reloading zone 45 as it is, and the completed compost can be received from the next container 1. The empty container 1 is a container truck 6
2 allows the compost to be carried out from the vehicle entrance / exit portion 46 for carrying out the compost.
