“…The exponential model successfully describes the drying kinetics of some porous materials, such as clay (Skansi & Tomas, 1995;Tomas, Skansi, & Sokele, 1994), Al-Ni catalyst (Sander, Tomas, & Skansi, 1998) and food materials (Tomas & Skansi, 1996). The authors also used this model to describe the changes of moisture content and drying rates.…”

“…Taking the best mass diffusivities values inside the brick (Table 2) for each drying-air condition obtained and applying the Arrhenius equation (Equation ( 14)), a linear regression was performed. Figure 12 shows the Neperian logarithm of the mass diffusivity for each air predicted by the simulations and Equation (16). From the analysis of this figure, we can see a linear behavior of this variable, and an excellent concordance between the results, with the coefficient of determination equal to 0.998.…”

“…It only considers moisture diffusion inside the material in the liquid phase, and the effects such as moisture evaporation and vapor transport are disregarded. This theory has been applied with success on the drying of clay [13,14], ceramic tile [15] and ceramic bricks [4,[16][17][18].…”

In the manufacturing process of ceramic brick, the step of drying needs the control of process variables to uniformly dry the porous material, producing a good end-product. The majority of numerical simulations involving drying of ceramic materials is performed considering only the solid domain, resulting in a very simplified and limited study. This way, the objective of this work is the analysis of the drying process with hot air of an industrial hollow clay brick inside the oven at different temperatures by using computational fluid dynamic (CFD). The results of the temperature and water mass distribution inside the brick and of air in the oven at different times of the drying process are shown, analyzed and checked with experimental data, and it was obtained in a concordance with the data. An equation to calculate the brick water mass diffusivity depending on the drying air temperature was proposed.

Drying of particles (pieces) in a fluidized bed affords better quality of end products, especially for better product structure and its shorter reconstitution time. Fluid-bed drying of different fruit particles has been investigated. Starting water content varies from grape berries 81•5% and peach 87•7% to apricot 86•9%. The temperature of fluidization varies from 70 • C to 100 • C at air velocities from 0•98 ms −1 to 5•2 ms −1. The product should be dried fruit with 10% to 14% of water content with good rehydration quality that varies from 8 to 20. Experimental data have been measured, relevant values have been calculated and a mathematical model introduced. The results have shown that drying of fruit in a fluidized bed produces dry fruit particles of improved quality in a much shorter time, with improved rehydration times and qualities, than in continuous belt-driers that are generally used.
