✦ Synopsis

Local temperature variations were determined in sand beds during drying. Two different particle sizes of 200 ~tm and 550 lam's were used in the experiments Drying was conducted at 80°C and 150 ° C. Highest temperature were observed at the bottom of the bed due to capillary lift during drying at 80 ° C Rapid evaporation at 150°C ambient temperature caused heat to be transferred from both the surface and bottom of the bed, so the coolest section was at the center Isothermal conditions were approached as the capillary size increased as in 5501am particle beds.
