Özet:

In this study, in the infrared heater drying oven designed and manufactured, the optimum drying temperature was determined by drying the nane plant at different temperatures. Nane leaves subject to the drying process in the drying oven are dry at temperatures of 50oC, 60oC, 70oC, 80oC and 90oC. Dry periods specific energy consumption, age and dry base moisture amounts are revealed. The drying processes of the nane leaves have been found that the initial moisture rate is 8.12 g of water/g of dry substance while this rate has fallen to 0.094545 g of water/g of dry substance. The individual energy consumption was between 21,10 MJ/kg and 52,08 MJ/kg. The quality of the dry product obtained in all experiments varies, while the optimal drying temperature is 70oC when the color, aroma, smell and energy consumption are assessed as a whole. In the drying processes under this temperature, the aroma and smell are increasing, but the energy consumption is also increasing. When drying processes are studied at temperatures above 70oC, the smell and smell are reduced, while energy consumption is reduced.
