A moisture sensor for direct installation in fluid bed dryers and granulators? This sensor uses an energy-efficient microwave field that penetrates the grains and detects the water molecules both in the core and on the surface. Continuous measurements are taken during the drying process. The measured values are independent of varying bulk density, varying particle size, distribution and color.
How does an in-line moisture analysis work in a fluid bed dryer?
1. The moisture of the granules can be checked during the drying process – without taking samples and without waiting for results.
2. During the granulation and drying process, part of the fluidized granulate constantly runs down the front surface of the sensor.
3. A low energy microwave field is generated on the front surface of the sensor and penetrates the grains. The instrument measures and analyzes the interaction of the field with the water molecules.
4. The instrument continuously calculates and displays the current moisture values. Measurements can be followed online via a connected PC and are also available, for example, for a PLC.
5. The moisture of the granules can be checked during the drying process – without taking samples and without waiting for results
Monitor your drying process; advantages of moisture measurement in a fluid bed drying process
- Real-time monitoring of moisture
- Measurement directly in the grains
- No manual sampling
- No interruption, restart of the process
- Avoid over dried batches
- Better workability of granular material
- Longer shelf life of the end product
- Savings in processing time
- Energy saving
Advantages of TEWS in-line moisture measurement for fluidized bed dryers
- Continuous automatic measurement of moisture ensures close monitoring and control of drying processes.
- Terminating the process at the right time reduces overdrying and the chance of a product spoiling.
- The built-in moisture sensor does not require time-consuming interruption and restart of the drying process to take samples.
