Abstract

A greenhouse solar dryer with heat exchanger was tested for salted catfish in Perlis, Malaysia at average solar radiation of 626 W/m2. The dryer consists of the heat pipe evacuated tube collector, electric heaters, blower, pumps, water tank, and green-house drying chamber. The average temperature of the drying chamber is 44°C. The drying time is 18 h (8h day time and 10h night time). The total energy required used is 294.98 kWh and the solar energy contribution is 60 % of the total energy. The electric heaters, and blower-pump power used is 29 % and 11 %, respectively. The moisture extraction rate (MER) and specific moisture extraction rate (SMER) obtained of 6.3 kg/h and of 0.385 kg/kWh, respectively. The values for exergy efficiency varied between 29 % and 82 % with an average of 46 %. Economic analysis showed that system is a payback period about 1 year.
