• Resumen

  • A rigorous model based on hydrodynamic considerations and mass and energy balances has been proposed for batch drying of fine sand in a fountain confined conical spouted bed. The results show that the proposed model predicts acceptably the evolution with time of moisture content in the solid and the final moisture content for the different operating conditions, with the mass transfer coefficient being the only adjustable parameter.
