Comparison of distillation kinetics
The kinetics of ethanol distillation using OAHD was compared
with that of HD (Fig. 3). Distillation with OAHD started much
earlier than HD methods: about half an hour for OAHD and
almost 1h for HD. This is due to the more efficient heating
in the ohmic system. Unlike the classical conductive heating
methods, ohmic heating can heat the entire sample almost
simultaneously and at a higher rate, therefore it is able to generate
heat inside products rapidly
