translucent dryer has the area of solar collector equal to 4.08 2 m and two set of 800 watt of electric heater. This
dryer capacity has about 50 kg. This research was experimented with striped snake-head fish and batrachian
walking catfish, under hot air drying condition of 40, 50 and 60 Ñ C, respectively. The results of drying process for
striped snake-head fish at 60 Ñ C was 42.57 2 evap MJ kg H O of specific energy consumption and 5.54 % of dryer
efficiency and 6 hours of drying time. For the drying process of batrachians walking catfish at 50Ñ C was 80.02
2 evap MJ kg H O of specific energy consumption and 2.98 % of dryer efficiency and 8 hours of drying time.
Keyword : electric heater, specific energy consumption, dryer efficiency
