Evaluating powder characterisation techniques to optimise a dry granulation process

An experimental study was done to determine the correlations between the dynamic, shear and bulk properties of granules and the roller compaction process variables applied to make them.

Dry granulation by roller compaction is a routinely applied continuous process to convert fine, difficult to handle powders into uniform granular products that flow freely and perform efficiently in subsequent manufacturing steps.

The advantages of roller compaction include relatively modest capital investment, low running and maintenance costs, and high energy efficiency. Particularly suitable for moisture- or heat-sensitive materials and those that require ultra-high containment, dry granulation is an important step in the production of many pharmaceuticals, foods and chemicals[...].

Gerteis Maschinen + Processengineering (Jona, Switzerland) is a market leader in the design and supply of premium roller compaction equipment. In this article, results from a collaborative study between Gerteis and Freeman Technology are presented, to identify powder properties that characterise dry granulates in a commercially relevant way and support the optimisation of roller compaction processes. The study assessed the potential of dynamic, shear and bulk powder properties within this context.

Successful start at the Interpack 2017

Successful start at the Interpack 2017 We enjoy very good response for our latest roller compaction technology at the Interpack. The new production roller compactor with containment and WIP cleaning functionality gained the most attention as companies require more capacities in oncology and hormone production. We are looking forward to more interesting discussion and exiting projects during the next days.


Interpack 2017

We are taking part in the Interpack trade fair in Duesseldorf for the third time to present our most recent innovations in roller compaction. We will display the following machines.

PACTOR® Line of Products
The PACTOR®-technology developed by GERTEIS® facilitates the processing of sensitive and problematic pharmaceutical formulations. One of its most noteworthy qualities is the process orientated machine design, which results in minimal temperature being applied onto the product and the possibility to process formulations with a density below 0.1 g/ml. The combination of an adjustable press roller design, roller gap control and the arrangement of the feeding system is unique on the market and permits consistent and reproducible process parameters. The streamlined machine concept allows for easy scale-up and site transfer. Ultimately, the Pactor® dry granulation system offers you the highest flexibility available on the market.

Macro-Pactor® Type C
The Macro-Pactor® is a production machine with a capacity of up to 400kg/h and a minimum quantity of 500 g for laboratory trials. Due to its contained machine design, the displayed Macro-Pactor makes it possible to keep OEL values down to 1 µg/m3.

The Mini-Pactor® is ideal for R&D and small-scale production since it can process a minimum quantity of 10g in trials but allows for a scale-up of up to 100kg/h.
