The stirring shaft 120 has a plurality of stirring blades 121 and is eccentrically positioned downward one side from the center (O) of the fermentation vessel 100 is installed to drive rotation. That is, the stirring shaft 120 is rotated by being located at a distance X, Y distance from the center (O) of the fermentation vessel (100).

This means that when the fermentation vessel 100 is rotated in one direction, food waste crushes are mainly gathered in one eccentric direction that rotates below the center O of the fermentation vessel 100, thus further crushing the food waste pulverization in the eccentric position. This is to cause the agitation to take place in a compound dilution.

The stirring blade 121 has a structure in which the forward feed vanes 121A and the reverse feed vanes 121B are alternately disposed on the rotational axis to mutually reverse the conveying direction of the pulverized product with respect to the longitudinal direction of the fermentation vessel 100. .
