In particular, it refers to a mixing, stirring, and diffusion device or mixing device suitable for liquids, etc. in a limited space. The stirring blades for such double-cylinder tanks during the process of enlarging and so on are known as the stem (b) of the rotating center hub (b0ss) a along the half-square diagram, as shown in the figure. The front end of the rod b extends vertically downward ^. For example, if the flat plate is fixed in the front end of the rod b extending vertically downward, and the conventional stirring blades in the tank are not well up and down, especially due to the limitation of the blade width, the yield is reduced: Performance The object of the present invention is to provide a dispensing device, which is a problem. == Lower The stirring blade can be manufactured in the upper and lower circulation especially in the limited efficiency like the double cylindrical groove.
