The lower edge of the discharge port is located at an angle of 30 degrees or more in a direction along the bottom cross-section arc from just below the rotation axis as a center, and repeats the forward / reverse rotation of the rotating means during the drying process of the garbage, When discharging the processed dust, the rotating means is rotated only in a direction in which the dust is moved to the discharge port side.

According to the above configuration, the garbage put into the garbage container is promoted to be dried by the hot air generating and stirring means on the upper side while being scraped up by the stirring blades. The scrapped garbage falls naturally when lifted above the rotating means, and is stirred and dried while effectively using the entire space in the container. Water vapor generated from the garbage is discharged from the exhaust port together with new air taken in from the intake port. The dried garbage remains in the garbage container, but its bulk has been greatly reduced, and since it has dried and its water activity has decreased, it will rot even if it is placed in the garbage container as it is. No garbage or mold is generated, and thus, the garbage can be successively put on the dried garbage and dried until the garbage storage container is full.
In addition, the dried garbage is gradually swept toward one of the side walls by rotating the stirring blades attached in an inclined direction in only one direction, and automatically discharged from a discharge port provided at least 30 degrees above the side wall. It can be discharged.

When the steam in the garbage storage container 1 is exhausted and drying is nearing the end, the temperature of the upper space, that is, the temperature detected by the upper temperature detecting means 16 is 100 ° C. while water vapor is present.
Although the temperature is kept before and after, when the steam disappears, it is detected that the internal temperature of the storage container 1 sharply rises, and the detected temperature of the lower temperature detecting means 8 starts to increase with the temperature increase inside the container. According to this information, the drying is completed and all the processes are completed.

Further, when heating is performed at full power after the start of operation, the lower temperature detecting means 8 is controlled by the amount of dust introduced.
Because the initial rise speed of the garbage is different, based on this information, the boil is maintained so that if the amount of garbage is large, large power is used, and if the amount of garbage is small, the appropriate amount of small power is used. The required power can be appropriately controlled, and uniform drying of the finish can be achieved.
