These machines are suitable for filling valve bags. Product feeding is carried out with a impeller system or air system. Electronic weighing is performed via coarse and fine feeding.

The device checks the previous bag and slows or accelerates the filling speed accordingly. The empty bag is placed in the first station automatically or manually by the operator. Fast or slow filling is carried out through 360° rotation of the machine body. Upon arriving at the bag release station, the bag is left on the belt and the filling procedure is completed.
