✦ Synopsis

This paper describes the experiments used to determine the kinetics of tea drying. New thin layer drying apparatus was designed and built to measure the very high rates of drying found at the start of drying, and the results show that the Lewis equation satis"es. The drying rate constant proved to be a linear function of temperature and air#ow rate, indicating that tea drying is not only di!usion limited but also a function of convection. The results were validated on independent experiments.
