Abstract

In the present study combined infrared and hot air dryer to dry a thin layer of pomegranate seeds. Three different levels of infrared power, namely: 200, 250 and 300 W and three different exposure distance "the distance between infrared heater and samples" of dying are 20, 15 and 10 cm with air temperature 40 oC and air velocity 1.5 m/s were studied. Drying time as affected by infrared power and exposure distance, compatibility of experimental data to some drying models, effective diffusivity "Deff", rehydration and cost analysis were also studied. The results show that the drying time decreased with increasing infrared power and decreasing exposure distance. Midilli et al model showed the best fitness to experimental data with average R2 0.9972. The maximum values of Deff were recorded at highest infrared power 300 W. The rehydration ratios ranged between 0.55 to 1.16 under various drying conditions.
