The main goal of the wind tunnel is to simulate the realistic conditions of a typical contact dryer.
Psychrometric properties of the air: 70 C and 60%
Air speed: 18 m/s
The main parts of the wind tunnel sitting on the stage of a fluorescent microscope.
A Part of the measurement system and humidity and temperature control systems.
Example of the time variation of the measured variables at the reference set-point. The dashed lines show the set points of each variable. Moisture content (MC) shows the mean moisture content in the sample.
Moisture content map measured in a typical drying experiment.
The effect of the fabric pattern can be seen during the drying.
