Measuring moisture in hard gelatin capsules and powder for tablets

The properties of hard gelatine capsules depend on moisture to a very high degree. Prior to automatic filling, the capsules need to be conditioned to attain a specific moisture level to ensure their physical properties are optimized.
Moisture content can be measured online in the dryer in order to verify whether the capsule moisture is met for further processing. Automatic sampling is carried out in a bypass system to monitor the hard gelatine capsules. The moisture in the pressed powder could also be measured prior to insertion in the tablet pressing machine.

Hundred percent inspection of tablets and capsules

As the production of pharmaceuticals has a tendency to increase continuous production control and documentation, there is a constant growing demand for 100% monitoring of all the weight in tablets produced and filled capsules.
The weights cannot be monitored 100% by using balances at the speed of modern production lines.

Moisture and mass measurement of tablet and capsules

The TEWS Elektronik MW 3011 microwave instrument returns 10,000 moisture and mass readings every second, therefore making it the perfect tool for the high-speed separate measurement of rapidly passing tablets and capsules. The number of objects measured per unit of time is limited solely by the speed at
which the objects are passed through the sensor - not by the measuring frequency. Microwave resonance sensors can be installed directly into the production machine or can operate in separate inspection equipment.
