Continuous granulation and drying for the pharmaceutical industry

QbCon® 1 – R&D

All developments start in a lab. Continuous processes also require lab-size equipment with small footprints that can handle even very small throughputs.
Continuous wet granulation and drying have been subject to discussion for some time in pharmaceutical research and development (R&D) of oral pharmaceutical solids.

Continuous granulation and drying with QbCon® 1 by L.B. Bohle

Granulation and granule drying also play a major role in continuous manufacturing. QbCon® 1 is the only system for research and development world-wide that meets the quality demands of pharmaceutical manufacture.

First of all, a short residence time of the granules in the dryer with a narrow residence time distribution is essential to be able to remove defective products in a targeted manner without having to discard a large portion of the batch.

Furthermore, narrow residence time distributions simplify the traceability of material in the continuous process, making it easier and less complex to trace finished tablets back to the basic products or to subsequently trace them from the basic products to the finished tablet.

Further important quality requirements for a dryer are

  1. Even, reproducible drying of all granules – especially of different
    sizes – over the entire process duration
  2. A small process chamber to keep the volume in the drying process as low as possible
  3. And, in particular, a long service life of the exhaust air filters without having to interrupt the drying process or even replace

Thanks to the small footprint, the QbCon® 1 is perfect for the smallest throughputs (nominal throughput: 0.5–2.5 kg/h).
