Abstract:
A vacuum hood for removing flour, dust, and other small particles from bakery products (dough pieces), including baffling which provides desired airflow paths adjacent leading and trailing edges of the hood. The hood overlies bakery products as the products are carried in pans on a conveyor belt moving in a path prior to baking. The hood has conduits for directing jets of air under pressure through orifices against the bakery products tending to lift the products at the same time that a vacuum is drawing particles of material inwardly under the edges of the hood to insure that excess flour, and other light particulate materials are drawn up into the hood efficiently without creating regions where the flour and particles may fall back onto the pans that are holding the bakery products. The air jets from above tends to circulate around the pockets in the bakery pans for the product causing currents that tend to lift the bakery products, so that crumbs, baking residues, and flour and any other dust particles are removed.
