Abstract (en)

A powdered material flow control device for filling a bag (100) comprising a first screw conveyor (2) for transporting the material. The device (1) also comprises a second screw conveyor (4) adjacent the first screw conveyor (2). Both screw conveyors (2, 4) are vertically arranged, and, inside a housing (6) defining an inlet port (8), a outlet port (10) for the material and a common inner chamber (12), The screw conveyors (2, 4) have dimensions such that the housing (6) is externally snugly adapted to the cross section of the bag (100), said first and second screw conveyors (2, 4) rotating at a synchronized speed. The invention also proposes a machine including the device, as well as a filling process that uses the device.
