MICROWAVE DRYING KINETICS OF A CLAY-PLATE

This study presents the development of an exponential model for the de scription of kinetics in the drying process of a porous material under the condition of dielectric heating. The model describes the changes in moisture content and in the rate of drying related to the duration of the process, as well as the moisture content in the material to be dried with the power of microwave drying as parameter. The item define d is the functional dependence of the model coefficients on the power of the microwave drying. An expression to compute the drying time as a function of the moisture content in the sample and the power of the m icrowave drying is suggested. The results of the experiment and those obtained from the application of the model based on the computed ratio between the moisture content and dry matter correspond to an extraord inarily high degree.
