The aim of this research is to evaluate the kinetics study of hot air drying with aloe vera (Aloe barbadensis Miller) as a specimen and also to find the influence of temperature in various kinetic models proposed. In hot air drying different temperatures ranging from 30–50˚C with an air velocity of 2.0 m/s is used. In this experiment the proposed mathematical models are studied they are Newton, Henderson-Pabis, Page, modified Page and Logarithmic model. Using the linear regression coefficient (R2), sum square error (SSE), root mean square error (RMSE) and Chi-square statistic (w2) the best fit quality is found. As the temperature range is increased the effective moisture diffusivity is also increased from 4.78 × 10 10 m2/sec to 13.45 × 10−10 m2/sec. From the mathematical models evaluated in this research the modified Page model gives the best result and fits into the experimental and predicted drying data.
