PURPOSE:To enable efficient agitation by separately fitting agitating blades to inner and outer rotating shafts which rotate around the same central axis in the opposite directions. CONSTITUTION:A double shaft composed of an outer shaft 1 and an inner shaft 2 is used as the rotating shaft of an agitator to which agitating blades 3, 4 are fitted. The shafts 1, 2 are held so that the outer shaft 1 rotates around the inner shaft 2, the shaft 2 is protruded from the lower end of the shaft 1 and the blades 3, 4 are separately fitted to the shafts 1, 2. Efficient agitation is enabled by rotating the shafts 1, 2 in the opposite directions. |
