[0012]

In the food waste disposer of the present invention, first, the food waste is stored in the processing tank and covered with the lid. At this time, since the lid is opened and closed by using a part of the communication pipe as a rotation support shaft, the work of attaching and detaching the communication pipe is unnecessary, and the flexible member may not be used.
Next, stirring and heating are performed. When the exhaust means is driven,
The air containing the steam generated in the processing tank is collected by the lid and guided to the exhaust means via the communication pipe. If the communication pipe is arranged so that the water droplet guide portion including the rotation support shaft portion inclines downward from the central portion of the processing tank toward the outer peripheral side, the water droplets condensed on the communication pipe can be easily discharged to the exhaust means. As a result, the water droplets formed by aggregation in the processing tank and the communication pipe do not return to the processing tank.
