MG2 Dosator Method

This method uses a hollow metal tube with a spring-loaded adjustable piston which is volumetrically adjusted to capture the desired powder quantity.

Harro Höfliger Drum Filling

In the drum filling equipment, powder is metered by boring a dosage in a ‘product dedicated’ vacuum drum, which rotates at the base of the powder bed. The powder dose is retained in the bore by vacuum until it is discharged into the capsule body.

Main benefits and characteristics:

  • High flexibility and adaptability to different dosages thanks to the variable geometry of the dosing chamber
  • 100% net fill weight by Multi-NETT system (capacitive sensor)

Main benefits and characteristics:

  • Extremely precise dosage thanks to the product specific design of each drum
  • Low powder compaction, resulting in improved aerodynamic performance
  • 100% net fill weight check by the Advances Mass Verification system.
