Drying characteristics of water chestnut kernels were evaluated at different air temperatures (50, 60 and 70 °C) in commercially available hot air tray dryer and sun drying. Drying rate of water chestnut kernels 1.1880, 1.6181, 2.6688 and 0.7249 g water/ g dry matter-min were found at drying temperatures of 50, 60, 70 ºC and sun drying (38 ± 5 ºC), respectively at 15 min time interval. The Midilli-Kucuk model fitted better on the basis of higher R 2 value (0.99978) and lower values of X 2 and RSME values as 0.0000162 and 0.004028784 at 60 °C.
