PURPOSE:To sufficiently stir a solution generating change in state between a gel state and a sol state, by arranging a cylindrical draft tube in a container and respectively mounting the first and second stirring members to the inside space and lower side space in the draft tube. CONSTITUTION:A suction 2 to be stirred is received in a stirring container 1, and the first screw blade-shaped stirring member 8 and the second turbine blade-shaped stirring member 11 are rotated. Hereupon, the downward flow C of the solution 2 to be stirred is formed in the inside space of a draft tube 3 by the first stirring member 8. Subsequently, the solution 2 is transferred to the lower side space of the draft tube 3 and further transferred as outward flow D by the second stirring member 11. Thereafter, the solution forms upward flow E in the outside space of the draft tube 3. Furthermore, the inward flow of the solution 2 to be stirred is formed in the upper side space of the draft tube 3. By this method, when the solution 2 to be stirred generates change in state between a sol state and a gel state during stirring, sufficient stirring can be achieved. |
