In addition to the fact that the agitating chambers are concentrically continuous around the rotation axis, a strong support structure such as the conventional tank is not required, thereby providing an advantage that the entire tank can be provided at low cost. In addition, in the stirring, since the stirring chambers arranged concentrically communicate with each other by sequentially changing the flow direction by 180 degrees, sufficient stirring and mixing can be achieved for the entire stock solution. Its use value is extremely high.
