 Abstract:

The specific energy consumption involved in the two drying processes was estimated from the energy supplied to the various components of the dryer during the drying period. The specific energy consumption was computed by dividing the total energy supplied by amount of water removed during the drying process. Tomato slices were dried from an initial moisture content of 15.9 to 0.17 gwater/gdry solids by involving infrared radiation and convection-infrared combination drying, respectively. Specific energy consumption for the tomato slices were compared at these different drying conditions. In particular, the experiments were carried out at three different infrared intensity levels 0.15, 0.2 and 0.3 W/cm2 and air velocity levels 0.5, 0.7 and 1 m/s under infrared drying. For combination of infrared and hot-air convection drying there were three air temperature levels of 40, 50 and 60oC and three air velocity levels 0.5, 0.7 and 1 m/s while the infrared intensity was set at 0.15, 0.2 and 0.3 W/cm2. Results of data analysis showed that the lowest and highest energy consumption levels in drying tomato slices were associated with the hot air convection-infrared combination and infrared dryers, respectively. In infrared drying, it was observed that increasing the air velocity increases the drying time and consequently the amount of energy consumed. However, a reduction in energy consumption was noted with increasing infrared intensities under combination drying relative to infrared drying alone.
