Abstract

The convective drying of glass-bead-packed beds containing sucrose/NaCl aqueous solution was examined at a wide range of steam partial pressures using room air to superheated steam at 160 °C. The sucrose distribution in the sample materials after drying was affected by the humidity of the drying media and the glass bead diameter. This indicated that the density gradient affected convection flow. The drying time of the sample material with NaCl aqueous solution at a steam partial pressure of 16 kPa (high-humidity air) was shorter than that under other conditions.
