Contamination-free raw material supply for sensitive products
When processing sensitive substances – for example for the production of bone cement used in orthopaedic surgery – a safe, dust-free and product-friendly raw material supply plays a crucial role.
For this, HECHT Technologie offers special big bag emptying stations with containment liner systems that enable contamination-free transfer of the material.
The highest material quality is ensured (stainless steel with a low surface roughness Ra).

Hygienic conveying and blending process with ProClean technology
For closed transport to the mixer, the specially developed ProClean Conveyor (PCC) is used, which features a hygienic design, compact filter technology and an energy-efficient plug conveying mechanism.
This technology minimises air consumption, reduces the risk of cross-contamination and meets all cGMP and FDA requirements.
Conveying takes place under vacuum to guarantee a closed product flow.
After conveying, the mixing process starts in a ploughshare mixer, which ensures homogeneous and reproducible mixing of the components.
Ease of use and hygiene are always central to mixing and to cleaning the systems.

Efficient and safe filling with the LBK-EC filling head
After mixing, the end product is conveyed by 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 allows simple, safe and fast filling without auxiliary materials or consumables.
The connection is made with a pneumatic inflatable seal and a mechanical lever clamp, which ensures reliable sealing and fixing of the liner.
This prevents particles from escaping and the product from being contaminated.
With its ergonomic operation, high operational safety and OEB 5 suitability, the LBK-EC sets new standards in dust-free, user-friendly filling technology – an essential factor in meeting high containment requirements in medical technology.
