Constant layer moisture at the hot surface is found to exist during the constant‐rate period of drying of sand on a hot surface in still air. It accounts not only for the constantrate period of drying itself but also largely for the length of the period. Temperature of the air‐surface interface usually has minor effects on the rate of vaporization because equilibrium between vapor and the bed is not established during periods of rapid vaporization. Numerical relationships have not been established.
