Abstract

The importance of thermodynamic analysis of various energy consuming and energy producing processes as essential tool for system design and optimization of thermal systems in order to achieve design technology and optimum tool performance cannot be underestimated. Hence, this research work examines the energy utilization and energy utilization ratio of drying process of onion fruit (Allium cepa) at different drying temperatures of 65OC, 75 OC, 85 OC and 95 OC and thickness of 0.50cm,1.00cm and 1.50cm in a cabinet dryer with automatic temperature control system. Preliminary results show that energy utilization and energy utilization ratio increased with an increase in drying air temperature but decreases with an increase in particle thickness. The maximum value of energy utilization was 61.3787 ������ and it was obtained at mass flow rate of 6.068 x 10-2kg/s, drying air temperature of 95OC and thickness of 0.50 cm. While the minimum value of energy utilization was 1.0439 ������ and it was obtained at mass flow rate of 2.69x10-1 kg/s, drying air temperature of 65OC and thickness of 1.50cm. The highest value of Energy utilization ratio was 0.6914 which occurred at a temperature of 95oC, thickness of 0.50 cm and mass flow rate of 6.068 x 10-2 kg/s while the lowest value of 0.01818 was obtained at drying temperature of 65oC, thickness of 1.50 cm and mass flow rate of 2.690 x 10-1 kg/s.
