In this study, drying characteristics of Syzygium cumini was experimentally investigated under the temperatures of 50 degrees C, 60 degrees C and 70 degrees C and the mathematical models were used to fit the drying of Syzygium cumini. Moisture transfered from Syzygium cumini was described by applying the Fick's diffusion model and the effective moisture diffusivity was calculated. The temperature dependence of the effective moisture diffusivity for the drying of Syzygium cumini samples was described by an Arrhenius-type relationship with activation energy. Drying data were fitted to seven drying models, namely Lewis, Henderson and Pabis, Logarithmic, Twoterm, Page, Wang and Singh and modified Henderson and Pabis. The Logarithmic model was found as the best fitted model in describing the drying behavior of Syzygium cumini.
