This study investigated the thin layer drying characteristics of bamboo slices in a convective tray dryer with three different temperatures viz., 55, 65 and 75 0 C and fit the experimental data to four drying models to identify the best fit model and drying temperature. The drying rate curves of slices typically demonstrate a smooth diffusion controlled drying behaviour. The drying rate at the beginning of the process was generally lower at 55 0 C with a marked difference between it and the other tem - peratures. The difference between moisture ratios increased gradually at the commencement of drying and the time required for reaching equilibrium moisture content decreased with increasing temperature. The average value of coefficient of determination (r 2 ) and RMSE revealed values varied between 0.94- 0.99 and 0.014- 0.073 respectively. Page and logarithmic models obtained the highest r 2 and least RMSE at all temperatures and better reflected the drying mechanism of bamboo slices than exponential model. Rehydration ratio elevated when salt solution used for rehydration and the weight gain was more irrespective of tempera - ture. Superior rehydration was noticed when the slices were dried at 65 0 C and it was relatively poor at 75 0 C and 55 0 C. Products dried at 65 0 C recorded highest scores for visual appearance and colour at the end of drying.
