Design and analysis of energy and exergy performance of an LPG-powered fish drying machine

A detailed design and analysis of the energy and exergy performance of a Liquefied Petroleum Gas (LPG)-powered fish drying machine are presented in this paper. The system designed is a modification to the conventional fish dryer which uses charcoal, electric or solar energy as sources of heat. The m...
