Thermodynamic and environmental analyses for paddy drying in a semi-industrial dryer

In the present work, the first and second laws of thermodynamics were used to perform energy and exergy analyses for deep bed drying of paddy in a convective dryer. Also, the equivalent specific CO2 emission was assessed. Drying experiments were carried out at drying air temperatures of 40, 50 and 60 °C, and air flow rates of 0.008, 0.012 and 0.017 m3 s−1. Energy utilization, energy utilization ratio and energy efficiency were obtained to be in...
