This moveable device is designed for the creation, observation and research of fluid bed drying processes. It supports continous and batch processing in open system and closed cycle system with optional bypass operation. It is designed for educational purposes and provides versatile studies in thermical, mechanical process engineering, measuring and control technique.

Measuring systems :

The measuring devices are digitally connected to the internal controller, sending serial data to the comprised portable PC. Stand control and data acquisition is performed by Windows-software. Measured quantities are:

• 3 x dry bulb temperature 0-120°C
• 3 x relative humidity, humidity ratio
• 2 x Quantity and mass flows
• Pressures up to 100 mbar

• PID-Controller for temperature (3- stage on/off control with feedback). The controller parameters can be set by the software. The proportional, integral and derivative actions of the output value can be extra recorded.
• Speed controlled side channel compressor
• Fresh air- / recirculating air control flaps
• Glass cyclone for bypass operation
• In-, back-, outlet, cell wheel sluices
• Regenerative bag filters
• Seeve-vibrator
• Manipulator
