Because process times can be many hours long, it is seldom practical to manually observe the drying process. That being said, process abnormalities that last for just seconds or minutes can cause so-called “pharmaceutical elegance” up to and including collapse of the product, resulting in the loss of a batch.
This is where Martin Christ turns to LyoCam: a high-quality, full HD industrial camera continuously photographs the product, at intervals varying from seconds to minutes, depending on the process stage. Event-controlled high-frequency recording is also possible e.g. for freezing with the LyoCoN (Controlled Nucleation) technology. The behavior of the ice condenser (build-up) can also be documented.
For futher information:
The key feature, however, is coupling images using the LPCplus SCADA system on the freeze dryer. In plain terms, a slider in the graphic interface for the process can be used to view the images in precise synchronization with the recorded data. The same applies to process stages in the event list. A perfect tool for process optimization and quality control.
