[0003]

However, even in the case of a household of 6 people or a household of 4 people, in which a large amount of garbage is produced, the amount of raw garbage remains in the vicinity of the upper limit in the process of disposal.
There is a small margin in the capacity, and the capacity for processing contents may be insufficient. That is, when the garbage is added to the vicinity of the upper limit, the contact area with the air is reduced, oxygen cannot be sufficiently supplied, and the fermentation cannot be performed smoothly. Therefore, the present invention, by increasing the capacity of the fermenter, the ability to process the contents is increased, oxygen is sufficiently supplied to the fermenter,
An object of the present invention is to provide a domestic food waste disposer capable of ensuring a good fermentation state of contents.

[0004]

The object of the present invention is as described above, and has the following structure in order to achieve the object. That is, in the present invention, the fermentation tank 2 is rotated, the microorganisms and the organic wastes in the fermentation tank 2 are stirred, and the fermentation waste is treated in a household garbage disposal machine, and the fermentation tank 2 has a substantially spherical shape. , The ratio of the length A, width B, and height C of the substantially spherical outer shape is set to about 1: 1: 1, and the capacity of the fermentor is set to 20.
It is about 0 liter.

[0005]

Next, the operation will be described. In the domestic garbage processing machine, the capacity of the fermenter 2 was set to about 200 liters, so that the contact area with the air was increased and the processing capacity was increased to allow a margin. Since the fermentation tank can be treated and the shape of the fermentation tank is substantially spherical, the fermentation can be carried out efficiently in every corner.
