- Adsorption Characteristics of Thin Silica-Gal Layer and Simulation in the Fixed Layer.
説明
The purpose of this paper is to design dehumidifier for drying at ordinary temperatures.<br>The adsorption characteristics of thin silica-gel layer were measured and analyzed as follows:<br>(1) The adsorption process of silica-gel was in the first falling rate period. (2) The relation between equilibrium moisture content and the relative humidity was expressed well by the formula of Chen-Clayton obtained by the method of least squares. (3) The latent heat of vaporization of water in silica-gel was calculated precisely from the Clausius-Clapeyron's equation. (4) The relation between the equilibrium moisture content and the absolute humidity in the same temperatures could be adequately approximated by linear formula.<br>From the results of above (1) to (4), unsteady state equations for heat and mass transfer in silica-gel particles and air were formulated. Using these equations the simulation of temperature and humidity of air through the fixed thick layer, and moisture adsorption and temperature in silica-gel particles, for the adsorption process was performed. The feasibility of the silica-gel dehumidifier for cereal grain dryer at ordinary temperatures was confirmed by the simulation.
