| Betel leaf or “Paan” is contemplated as “a neglected green gold of India” due to its nutritional, financial, medicinal, social and cultural values. However, surplus production of the leaves during the glut season and lack of adequate storage facilities compel the betel leaf growers to sell it at a through away price. Therefore, the current study was taken up to enhance the shelf life of the leaves by four different drying methods like shed drying, hot air oven drying, vacuum drying and freeze drying. Eight different thin layer drying models were studied and compared based on coefficient of determination (R2), root mean square error (RMSE) and chi square. The results showed that Page model was the best fitted model for hot air oven drying and vacuum drying... |

| Abstract: Studies on modeling of thin layer drying kinetics of grape juice concentrate were conducted using pilot scale convective dryer. Experiments were conducted in temperature range of 55-750C and drying bed thickness of 3-7 mm, to attain desired moisture content (14±1% db). Different thin layer drying models like newton, page, logarithmic, two term, two term exponential and midilli models were fitted to the experimental data of convective dehydration and their adequacy of fit was investigated. All the samples witnessed falling rate period drying irrespective of the selected temperature and thickness. The effective moisture diffusivity and activation energy were found in range of 7.18-2.56 m2/sec and 26.07-21.59 kJ/mole respectively for 3-7 mm... |
