Demonstration Capabilities
– Demonstration of drying rate regimes
– Heat and Mass Transfer
– Drying tests on solids for industrial use
– Effect of temperature and air velocity on drying rates
– Use of psychrometric charts.
Comprehensive instrumentation is included and the measured values recorded on the computer:
• Weight of trays plus contents (with Tare function)
• Temperature (dry bulb) and relative humidity of the heated air before the trays
• Temperature and relative humidity of the air after passing over the trays
• Air Velocity
From each pair of temperature and RH readings the full thermodynamic properties of the air can be determined using a psychrometric chart, i.e. the wet bulb temperature, the moisture content and the entropy. This allows for a more in-depth analysis for project or research work, for example comparing the change in moisture content of the air with the rate of moisture loss from the trays.
