The speed reducer output shaft has a disconnectable connection with an agitator shaft that extends transversely within the sifter tube, such that when the motor is energized the agitator is rotated to pulverize flour particles located on a sifter screen in the sifter tube. Flour particles gravitate through screen openings into a collection receptacle placed below the sifter tube. The sifter unit can be removed from the stand for cleaning or storage.
