Resumen: The influence of the contactor angle, gas inlet diameter, particle diameter, length of the draft tube and height of the entrainment zone on the average cycle time in a novel conical spouted bed dryer with a draft tube has been analyzed by a two-level factorial experimental design to optimize the drying process at low temperature. The effect of these factors has been determined by a statistical analysis. An empirical correlation to calculate average cycle time in a novel conical spouted bed dryer with a draft tube has been proposed.
