Off-Design Exergy Analysis of Convective Drying Using a Two-Phase Multispecies Model

The design of a convective drying cycle could be challenging because its thermodynamic performance depends on wide range operating parameters. Further, the initial product properties and environmental conditions fluctuate during production, affecting final quality, impact, energy usage. An off-design analysis distinguishes effects different parameters defining setup with best more stable performance. This study analyzes reference scenario configured as an existing system three upgrades to recover supplied avoid heat air dumping in atmosphere. We calculate their for seasons, moisture, input/output rate, two products. comprises 16 simulation cases, solutions two-phase multispecies Euler–Euler model that simulates equilibrium all components. Results discuss combination maximizes evaporation rate produces highest benefits global up doubling levels. advantages recovery vary by amount wasted energy, increasing exergy efficiency maximum 17%. Energy needs recirculation cut at least 50%. Concluding remarks present technical guidelines reduce use optimize production.
