Drying characteristics of Mulberry (M. alba) including sorption isotherms and drying kinetics were investigated. Adsorption and desorption isotherms at 10, 20 and 30 °C and isosteric heats of sorption were determined. At higher water activities, as the temperature was increased, a crossing of the isotherm curves was detected. Some hysteresis effect decreasing with higher temperature was observed. Mulberry was dried in a pilot plant tray drier with a constant air velocity of 1.2 m s−1 at 60, 70 and 80 °C. Only falling rate drying periods (three falling rate periods) were observed in the mulberry drying experiments. The diffusivity values changed from 2.32 × 10−10 to 2.76 × 10−9 m2s−1 within the given temperature range. Effect of temperature on the diffusivity was expressed by an Arrhenius relation with an activation energy value of 21.2 kJ mol−1.
