ABSTRACT

The dehydration kinetics of curry leaves were investigated. Convective oven dry method was employed at four different temperature such as 70, 80, 90 and 100°C the resulting experimental values were input into three thin layer model such as Henderson-Pabis, Page and Lewis Model. Henderson-Pabis model ranges from 0.9992-0.999, 1.657x10^-5 – 7.1 x10^-5 and 0.000832437- 0.003683804 for R² , X² and RMSE respectively. Investigation indicates that drying process falls under the falling rate period like other biological materials. Amongst the three different model evaluated Henderson-Pabis model gives perfect description for predicting the curry leaves closely related to the Lewis model after subjected to mathematical analysis of the drying sample and within the temperature studied in this research, the dependent effective moisture diffusivity ranges from 6.99x10^-8 - 3.93 x10^-7m/s. The related activation energy value obtained was 42.49-kJ/mol.
