Abstract
The possible sources of the energy losses in the drying systems can occur in the drying chamber and solar collector. The energy from these parts were not properly utilized so it is evident to further search for improvements. Energy and exergy analyses were being used to identify the possible source of inefficiencies quantitatively and qualitatively in the drying system and aid in recommendation for its improvement. This study aimed to evaluate the performance of an onshore drying system for seaweeds by conducting energy and exergy analyses. It has shown that the dryer efficiency was 33.58% and its solar collector efficiency was 68%. The exergy efficiency was obtained as 41.38% relates to an exergy improvement potential of 256.30 W. It is recommended to perform partial to full exhaust air recirculation and provide thermal storage may boost the exergy efficiency hence minimizing energy losses in the drying system.
