2. The air outlet of an air distribution device generally adopted by the existing fermentation tank is positioned within the working radius of the stirring paddle, so that the air is usually gathered within the radius of the stirring paddle along with the rotation of the stirring paddle and moves upwards, and sometimes an air mass is formed at the lower part of a stirring paddle blade, so that the dissolved oxygen of the fermentation liquor close to the wall part of the tank is insufficient. Also, the air ejected from the air distribution device generally rises along the shortest path, resulting in low air utilization.

3. The existing fermentation tank usually forms mixed flow in the vertical direction and the radial direction in the interior, and effective circulation cannot be formed, and the fermentation liquor heat exchanger is arranged close to the side of the tank wall, so that the temperature difference caused by uneven heat exchange exists.
