Thin Layer Drying of Peeled Longan (Dimocarpus longan Lour.)

In this paper, thin layer drying of peeled longan is presented. Thin layer drying of peeled longan was conducted under controlled conditions of temperature and relative humidity. Drying air temperature has great influence on the drying rates of peeled longan and drying time decreases with the increase in drying air temperature. Eight different thin layer drying models were fitted to the experimental data of peeled longan. The drying parameters of peeled longan were function of air temperature and relative humidity. Page model was found to be the best and Two-term model was found to be next to the best. The agreement between the predicted and experimental values for Page model is excellent. The predictions of Page model, Two-term model and…
