The disclosure relates to a filling device and to a filling system for volumetric metering of powder in a metering container. The filling device includes a retaining device permeable to air but impermeable to the powder. The retaining device in the course of the metering process covers a filling aperture of the metering container and a rim of the metering container encircling the filling aperture, a filling pipe which has been passed through the retaining device into the metering container, and first underpressure generator for generating an underpressure or partial vacuum on the retaining device on the side thereof facing away from the metering container. The filling pipe exhibits a blocking portion, the blocking portion being at least partially permeable to air but impermeable to the powder. The filling device includes a second underpressure generator for generating an underpressure on the blocking portion on the outside thereof.

Filling device and filling system for volumetric metering of powder

The disclosure relates to a metering apparatus for free-flowing material and to a method for operating such a metering apparatus. The metering apparatus has a metering duct having a closed cross section and further has a rotary drive (M). The metering duct is wound in the form of a screw with a vertical longitudinal axis. The free-flowing material is fed to the metering duct. The metering duct is set via the rotary drive (M) in an oscillating rotary motion about its longitudinal axis with individual rotary strokes, wherein, with each rotary stroke, a partial quantity of the free-flowing material falls out of a lower discharge opening of the metering duct.
