Kind Code:
A1
Abstract:
[PROBLEMS] To provide a fermentation tank of the aeration/agitation type by
which aeration/agitation can be stably conducted even in a small liquid amount
and the fermentation efficiency can be elevated. [MEANS FOR SOLVING PROBLEMS]
A fermentation tank of the aeration/agitation type (10) wherein a fermentation
liquor (S) is filled in a tank (11) having a cylindrical body (12), a cover (13)
and a bottom (15) provided respectively above and below the body (12), and then
the fermentation liquor (S) is aerated/agitated by rotating self-suction agitation
blades (18) provided at the center of the bottom (15) of the tank (11). In this fermentation
tank, an inverted cone-shaped slope (14) is continuously formed between the
lower opening (12b) of the body (12) and the outer periphery (15b) of the bottom
