Drying of coal in steam offers, besides reduction of ยฎre and explosion hazards, improved thermal efยฎciency. In addition, steam-dried coals appear to be less prone to spontaneous combustion. In a previous paper, a mathematical model was developed for the drying of a single porous particle in steam. I

The results of drying tests in a fluidized bed and a tray dryer are reported for typical tablet granulations. The data are analyzed to give estimates of total drying times, rates of dryin and overall heat transfer coefficients in each unit. It is concluded that fluidized f e d drying of tablet granu
