Analysis of moisture profiles, mass biot number and driving forces during drying of potato slabs

The drying of shrinking bodies is analysed by numerically solving a drying model in order to obtain a deeper insight into the drying process, calculating moisture profiles and various forms of Biot number. Moisture profiles shows great differences when different units of concentration are used. Calc...
