Abstract:

Dielectric heating was incorporated into the existing continuous single-zone convective dryer model. The energy balance equation for a control volume around the drying product was nondimensionalized, and the resulting dimensionless parameters were used to generate a unique characteristic drying curve and to define drying regimes for dielectrically enhanced drying. Numerical models were developed to represent the heat generation inside the wet product and the position of the evaporative front as a function of moisture content. The governing equations were modified to account for the thermal influence of vapor flux in the dry region. The enhanced computer code is capable of predicting the drying rate and temperature history for the product, and calculating the required dryer length, and the drying time for dielectrically enhanced drying.
