Potato thin layer convective dehydration model and energy efficiency estimation

The dehydration parameters (temperature, thickness, and mass load) statistically significantly (p<0.05) affect the thin-layer convective of potato slices. slices with thicknesses 3, 5, 8 mm were dehydrated as monolayers at different temperatures (30, 50, 70 °C) load (1.00, 0.63, 0.38 kg m-2). results showed that shortest time (183 minutes), smallest energy consumption (0.176 kWh), emission carbon dioxide (0.17 kg) had model a 3 m-2 load, on temperature °C. Dehydration slice thickness °C, highest resistance to transfer (the maximum effective moisture diffusivity 2.3761 × 10-7 ± 4.45646 10-9 m2 s−1) minimum activation (27.02 kJ mol-1). Data obtained from these mathematical models could predict optimize thin layer slices, dominant influence variables.
