There is provided a stirring device including a stirring tank including an inner peripheral wall which is circular in cross section, at least one circulating impeller and at least one dispersion blade which are located inside the stirring tank and rotatable around a vertical axis independently of each other, and a guide ring disposed radially outward near the dispersion blade. The circulating impeller is disposed along the inner peripheral wall of the stirring tank, and rotates around the vertical axis to form at least a downward flow in a stirring object existing inside the stirring tank. The dispersion blade rotates to apply a shear force to the stirring object, and is disposed at a radially inner position of the stirring tank from the circulating impeller, and at a position in contact with a flow of the stirring object, which is formed by the circulating impeller.

Planetary gear mechanisms require internal toothed gears in housings. A drive rotor and driven rotors are accommodated in a mixing space in a housing, and chemical inflow paths to the mixing space are formed in an upper portion of the housing. A mixture outflow path is formed in a lower portion of the housing. The mixing space is formed to allow the drive rotor and the driven rotors to rotate and to regulate the positions of the drive rotor and the driven rotors. Meshing the drive rotor with the driven rotors allows the driven rotors to rotate opposite to the rotating direction of the drive rotor accompanying the rotation of the drive rotor while the lower ends of the driven rotors are located above a bottom portion of the mixing space and the upper ends of the driven rotors are located below the lower surface of the lid body.
