PURPOSE:To enhance recirculation function and to uniformize shearing speed distibution, by providing a spiral strip shaped stirring blade connected to the rotary shaft concentric to a container main body between the outer peripheral surface of the container main body. CONSTITUTION:When a rotary shaft is rotated to the direction shown by the arrow, the liquid held between a draft tube 8 and a main body container 1 is pushed up to the upper part by a spiral strip blade 10 and further flowed down through the draft tube 8 from the upper part thereof toward the lower part thereof to be again returned to the outside of the draft tube 8. By this recirculation, the liquid is locally mixed at first while receiving shearing action by the spiral strip blade 10 and subsequently also receives shearing action by guide plates 11, 12 in the draft tube 8 and is advancing while receiving local mixing and changes in its mutual position by the twist of said guide plates 11, 12. |
