Abstract
Abstract Maintaining a constant drying rate during the drying process is difficult in organic solvents with high evaporation rates. The liquid supply method was adopted in this study to evaluate the drying characteristics during a constant drying rate period. Accordingly, the effect of the absolute humidity of water vapor on the drying characteristics was examined. With an aqueous ethanol solution, the water vapor in the drying gas dissolves in the liquid phase on the material surface, and the gas-liquid equilibrium governs the drying characteristics. With n-hexane, the water vapor in the drying gas condenses on the surface of the drying material. Although water does not dissolve in the liquid phase, it affects the drying characteristics.
