Resumen: In order to optimize the drying process at low temperature, the influence of geometric factors and operating conditions on drying time of wet coarse particle of sludge in a conical spouted bed dryer has been analyzed by means of a factorial experimental design. The effect of the geometric factors and operating conditions on drying time has been determined by a statistical analysis. Operation regimes of beds consisting of wet coarse particles in a conical spouted bed dryer have been determined by pressure drop fluctuations at inlet gas temperatures from room temperature up to 120 ºC. Results of drying modelling for beds of coarse particle wastes at different regimes have been verified through some experimental drying time of sludge.
