Contamination-free supply of raw materials for sensitive products
When processing sensitive materials – such as bone cement used in orthopaedic surgery – a safe, dust-free and gentle feed of raw materials plays a crucial role.
HECHT Technologie offers specialised big bag unloading stations with containment liner systems for this purpose, which enable contamination-free transfer of the material.
In doing so, the highest material quality (stainless steel with Ra
The weighed raw materials are fed into the subsequent process in precisely measured doses – an important step in ensuring product quality.
Hygienic conveying and mixing process with ProClean technology
The specially developed ProClean Conveyor (PCC) is used for closed-system transport to the mixer; it features a hygienic design, compact filtration technology and an energy-efficient plug-conveyor mechanism.
This technology minimises air consumption, reduces the risk of cross-contamination and meets all cGMP and FDA requirements.
The conveying process takes place under vacuum to ensure a closed product flow.
Following transport, the mixing process begins with a plough-blade mixer, which ensures homogeneous and reproducible mixing of the components.
Ease of use and hygiene are always the primary focus, even during the mixing and cleaning of the systems.
Efficient and safe filling with the LBK-EC filling head
Following the mixing process, the finished product is transported via a vacuum conveyor to two filling stations, where it is filled into big bags.
For this sensitive process, HECHT developed the patented LBK-EC (‘Easy Connect’) filling head for containment applications, which enables simple, safe and rapid filling without the need for auxiliary materials or consumables.
The connection is made via a pneumatic inflation seal and a mechanical lever-clamping device, which ensures that the liner is reliably sealed and secured.
This prevents particles from escaping or the product from becoming contaminated.
Thanks to its ergonomic operation, high occupational safety standards and OEB 5 compliance, the LBK-EC sets new standards in dust-free and user-friendly filling technology – a key factor in meeting the high containment requirements of the medical technology sector.
