<p>PROBLEM TO BE SOLVED: To provide a paddle agitator which lessens the fluctuation of a splashing state and the loss due to vibration and load fluctuation and is used for a paddle fermenter operative stably by small driving powder. SOLUTION: Front end shapes 3 of agitator blades 2 of the paddle agitator radially having the plural agitator blades 2 are configured to flat planar shapes toward a revolving shaft 5. The agitator blades are preferably constituted by disposing flat planar spur tooth segments only at the front ends, providing the segments not disposed with the spur tooth segments with projections 6 of arbitrary shapes and disposing these projections so as to draw concentric circles at each of the plural agitator blades by shifting their configuration positions. The agitator blades are recommended to be installed with reinforcing ribs 4 on the front and back in the rotating direction of the agitator blades.</p> |
