Sažetak
The mass and heat transfer properties of clay plate subjected to convection drying were investigated in laboratory scale at different drying potential of humid air. Dimensionless moisture and temperature distributions of samples were obtained at constant air velocity and used for determination of moisture and heat process parameters (lag factor and drying coefficient) by using the simple exponential equation. The thermal diffusivity, heat transfer coefficient, moisture diffusivity and moisture transfer coefficient for clay plate were assessed from evaluated process parameters according to analytical technique that proposed by Dincer for determination of transfer parameter for wooden slabs subjected to drying. The used Dincer analytical method can be employed for assessing the transfer properties and drying kinetics in easy and effective manner. The assessed values of Biot number (0.1 < Bi < 100) were suggested the presences of certain internal and external resistances to heat and mass transfer during clay drying at experimental conditions. The drying potential of humid air influences the moisture and heat transfer parameters.
