Abstract
A filling nozzle for use in filling a valve bag eliminates sifting of product during and after the filling operation. A body member, adapted for insertion into the valve sleeve, has a material passage therethrough adapted to direct a stream of product emerging therefrom through the valve. A vent is provided, connected to a first conduit, for continuously drawing a low vacuum between the nozzle and the sleeve, both during and after the filling operation, to remove any product particles there present. A second conduit is provided for introducing a high pressure blast of air into the material passage to remove any product remaining therein after a bag has been filled. Finally, a third conduit is provided for drawing a high vacuum in the material passage to remove any particles remaining therein after the filling operation has been completed. The body member is tapered, with a configuration like a duck bill, so as to provide an effective seal between the nozzle and the valve sleeve and to fully occupy the sleeve so as to eliminate voids wherein product could become entrapped.
