A flour recycling system includes a compressed air and vacuum head placed over a bakery product conveyor line. Flour is removed from the product units and is conveyed through a vacuum hose to the inlet of a remotely located dual stage separator in which the flour with entrained dough particles is subjected to a two-stage vacuum induced centrifugal separating process. Cleansed flour is drawn by vacuum through two fine mesh sifter screens into two reclaimed flour tanks each containing a vortex eliminator and each having an air release bag. Reclaimed flour is delivered to storage receptacles beneath the tanks through elongated flexible chutes which can be tied off and closed at desired elevations. The tanks, their air release bags and flexible chutes can be individually vacuum cleaned without shutting down the system merely by stopping the operation of one blower while continuing to operate the other blower of the dual blower system, one for each tank.
