Resumo: | The drying stage is the most relevant procedure in the industrial production of ceramic bricks, since the final quality of the product is directly related to the success of this operation. Knowledge of the material's thermal and mass diffusivity facilitates mathematical modeling, which brings us a greater domain of the process. With this purpose, the drying of solid ceramic bricks with different percentages of diatomite tailings was experimentally carried out in an oven with forced air circulation. The experiments were performed based on a 2k experimental design with three factors: the drying temperatures (333 and 383 K), the homogenization time of the mixture (30 and 60 min), and the percentage of tailings (10 and 30%). From the results matrix, we applied the Levenberg-Marquardt algorithm to minimize the difference between the theoretical and the experimental drying and heating curves, thus obtaining the thermal and mass diffusivities. Still in possession of the results matrix, we applied a regression model in order to obtain an equation to estimate the diffusivity values. The drying and heating curves that were built from the estimated diffusivities showed good agreement with the experimental data, and were validated within a 99% confidence interval. |

El conocimiento de la difusividad térmica y másica del material facilita el modelado matemático, lo que nos aporta un mayor dominio del proceso. Con este propósito, se realizó experimentalmente el secado de ladrillos cerámicos macizos con diferentes porcentajes de relaves de diatomeas en un horno con circulación de aire forzado. Los experimentos se realizaron en base a un diseño experimental 2k con tres factores: las temperaturas de secado (333 y 383 K), el tiempo de homogeneización de la mezcla (30 y 60 min), y el porcentaje de relaves (10 y 30%). A partir de la matriz de resultados, se aplicó el algoritmo de Levenberg-Marquardt para minimizar la diferencia entre las curvas de secado y calentamiento teóricas y experimentales, obteniendo así las difusividades térmica y másica. Todavía en posesión de la matriz de resultados, aplicamos un modelo de regresión para obtener una ecuación para estimar los valores de difusividad. Las curvas de secado y calentamiento que se construyeron a partir de las difusividades estimadas mostraron una buena concordancia con los datos experimentales y se validaron dentro de un intervalo de confianza del 99 %.A etapa de secagem é o procedimento mais relevante na produção industrial de tijolos cerâmicos, pois a qualidade final do produto está diretamente relacionada ao sucesso desta operação.

Para tanto, foi realizada experimentalmente a secagem de tijolos cerâmicos maciços com diferentes porcentagens de rejeitos de diatomita em estufa com circulação forçada de ar. Os experimentos foram realizados com base em um delineamento experimental de 2k com três fatores: as temperaturas de secagem (333 e 383 K), o tempo de homogeneização da mistura (30 e 60 min) e a porcentagem de rejeitos (10 e 30%).
