In addition, the drainboard 58 is arranged so as to form a space between the conical bottom surface of the fermented material sealed container 50,
The extract is collected in the space between the drainboard 58 and the drainboard 58.

[0028]

The breather attached to the fermented material hermetic container of the present invention has a water repellent treatment applied to a porous filter having a function of passing gas but not liquid, so that unnecessary water is fermented. It is possible to prevent the intrusion into the airtight container. Then, since the outside air is appropriately circulated, it is possible to optimally reproduce the bio-bacteria. Furthermore, if gas is generated in the fermented material sealed container, it is gradually discharged while being filtered by a filter, so that a bad odor can be eliminated.

Furthermore, since the breather of the present invention promotes fermentation, the capacity can be improved even if the fermented material sealed container is made small. For this reason, it is possible to expect an effect that the installation place becomes smaller and the size is reduced to lower the cost and make the purchase easier.
