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.
