Potato slices with thicknesses of 3, 6, and 9 mm were dehydrated as monolayers at different mass loads (1.00, 0.63, and 0.38 kg m-2) and microwave power levels (80, 240 W). The optimal model of potato slices with a 3 mm thickness, 0.38 kg m-2 mass load, dehydrated on 240 W, had the shortest dehydration time (15 minutes), the most negligible energy consumption (0.064 kWh), and the most insignificant emission of carbon dioxide (0.063 kg). The model of potato slices of 9 mm slice thickness dehydrated on 240 W, with 0.38 kg m-2 mass load, showed the highest resistance to mass transfer (the maximum effective moisture diffusivity 1.1847 × 10-7 ± 2.6080 × 10-9 m2 s-1). The average activation energy for all models was determined to be 11.635 W g-1. The thinner potato slices showed better results in dehydration time and energy consumption and good moisture diffusivity.conferenceObject10.1051/e3sconf/2021279010182-s2.0-85144731364
