Energy and Exergy Analyses in Combined Microwave and Vacuum Drying Process of Porous Packed Bed
This paper is concerned with the energy and exergy analyses combined microwave and vacuum drying process of porous packed bed were investigated. Drying experiments were conducted to find the effects of porous particle size and thermodynamics conditions on energy and exergy profiles. An energy analyses was performed to estimate the energy utilization by applying the first law of thermodynamics. An exergy analyses was performed to determine the exergy inlet, exergy outlet, exergy losses during the drying process by applying the second law of thermodynamics. The results show that energy utilization ratio (EUR) and exergy efficiency depend on the particle size as well as hydrodynamic properties, considering the interference between capillary flow and vapor diffusion in the porous packed bed.
