However, when trying to stir a high viscosity liquid north of several hundred Pa-5 (several thousand poise) with a conventional stirring device, the first
As shown in FIG. 1, there was a problem in that the liquid to be treated 21 near the center of the inner spiral blade 7 rotated with the rotation of the inner spiral blade 7, resulting in poor stirring and mixing.

The device described above has a plurality of helical blades having different outer diameters and a screw attached to a single rotating shaft, and a fixed cylinder that partitions between the respective helical blades and the screw. In this device, the liquid to be treated 21 near the center of the inner spiral blade 7 as shown in FIG. 11 can be moved by the screw in the fixed cylinder, but as the liquid viscosity becomes higher, There were problems in that the attached liquid rotated together and a dead space was created at the upper and lower ends of the fixed cylinder.
