Research Topic


One concept within the chemical and pharmaceutical industry is process intensification. This approach should lead to more efficient processes.

In the process step “direct compression” tablets were produced by compressing dry powder without any pretreatment strep. In this work specific subareas of this simple method to manufacture tablets, namely “die filling”, “blending” and “lubrication”, should be investigated.



A tablet is a solid single unit dosage form made by compressing dry powder blends or granules[1]. As they offer a number of advantages, for example high patient compliance and the simplicity in production, they are the most common drug delivery system today. Difficulties can occur due to poor powder flowability and segregation of powder blends. In addition, lubrication is a critical step as it could influence the final product properties.[2] 

The aim of this work is increasing the productivity of direct compression on a tablet rotary press. Therefore the description of the powder flow into the dies, the integration of a continuous mixing step and modifying external lubrication are core issues.
