Packing Head Systems

Hosokawa offers a range of inflatable packing heads designed to deliver dust free loading and discharge of powders which may pose a threat to health and safety of operatives and or loss of product into the surrounding pack-off or process area.

The integration within internal extraction and purge facilities delivers a high level of primary containment by providing a sealed connection between the filling device and container and is suitable for use with drums, bags, boxes and IBCs. Vented and extraction type sealing heads available for use when container pressure must be avoided. Displaced air escapes to atmosphere or can be extracted through an appropriate filter system for total plant hygiene and operator safety. Packing Head Systems can be incorporation within secondary containment systems including downflow booths, laminar flow booths and glovebox/isolators.

How it Works

The packing head is aligned with the receiving container — whether a bag, drum, or bin — and forms a tight seal via liner clamping, an inflatable collar, or docking interface. Product is then discharged from the upstream process equipment into the container. Built-in dust extraction and optional HEPA filters ensure the environment remains clean, while integrated weighing systems manage fill accuracy. Once filling is complete, the head disengages and the sealed container is safely removed, ready for further handling or transport.
