ABSTRACT:
A flour sifter has an upright cylinder within the interior of which a screen is disposed generally transversely to cooperate with an agitator movable over the screen to effect the sifting of flour therethrough. Affixed across the lower end of the cylinder is a first plate which includes a circumferentially-spaced first series of openings successively separated by respectively interposed first panels. A second plate, juxtaposed with the first plate, is movable about an axis extending centrally of the cylinder and includes a circumferentially-spaced second series of openings again successively separated by respectively interposed second panels. Those second openings are alignable with the first openings upon movement of the second plate to one position and are alignable with the first panels upon movement of the second plate to another position. Included on each of the panels of the uppermost one of the plates is a smooth surface that slants upwardly from one opening in that one plate to a peak from which the surface then slants back downwardly toward the next opening.
