PURPOSE:To make it possible to attain an available stirring state, by a method wherein plural stirring blades are provided to the inner peripheral surface of a cylindrical main body so as to be protruded therefrom in a spiral pattern and plural spiral stirring blades having a twist reverse in the direction relative to the above mentioned stirring blade are further provided to the upper half part of the outer peripheral surface thereof in a protruded state. CONSTITUTION:Plural stirring blades 4 having a shape formed by spirally twisting a strip like plate are provided to the inner peripheral surface of a cylindrical main body 1 opened at the top and the bottom surfaces thereof in a protruded state and plural stirring blades 3 comprising a spiral strip like plate and having a twist reverse in the direction relative to that of the stirring blade 4 are provided to the upper half part of the outer peripheral surface thereof in a protruded state. By rotating this main body, convection recirculative flowing is forcibly generated to a stirred liquid while natural vortex flow is partially generated during this procedure and a good stirring state is attained in a wide range from a low viscosity liquid to a high viscosity liquid. |
