Abstract

In this work z-directional moisture and temperature profile of fine paper was studied. Paper samples had different drying boundary conditions. Goal was to find out differences arising from drying conditions that can be used in papermaking. Paper temperature and moisture during drying was changed using different impingement drying parameters to the paper on a small scale drying device. A near-infrared spectroscopic method and measurement system for moisture depth profiling was used to measure moisture and thermocouples were used to measure temperatures in the thickness direction. Results measured were also supported by simulations using simulation software developed earlier. This study shows that during paper drying there exists great differences in z-directional moisture profiles that are up to 25-35% in moisture content, depending on the drying conditions. This difference is seen in measurements and also simulations.
