Modeling Ultrasonically Assisted Convective Drying of Eggplant

摘要: Modeling constitutes a fundamental tool with which to analyze the influence of ultrasound on mass transfer phenomena during drying. In this work, study effect power application drying kinetics eggplant was addressed by using different models based theoretical (diffusion) or empirical approaches. Drying cylinders (height 20 mm and diameter 24 mm) were carried at 40°C 1 m/s applying ultrasonic powers: 0, 6, 12, 19, 25, 31, 37 kW/m3. The experiments out least three times each power. Shrinkage sorption isotherms also in order attain an optimal description Applying sped up kinetics. identified as having significant (p < 0.05) both effective moisture diffusivity coefficient, well explained linear relationships. most complex model, considered both...
