    Improving Indirect Heat Transfer To Solids By Better Mixing

    A high ratio of heat transfer surface to process volume. Also as the size increased, the ratio did not decay as rapidly as with other dryers available then. Horzella (9) provides a plot of the effect on agitation on the rate of heat transfer. He also found that the type of material processed does have an effect on the rate of heat transfer (Figure 4).

    Zusammenfassung. To avoid heat transfers from the granular material to the wall of the dryer and to the air over the bed sur- face, hot water was circulated in the jacket and hot air was passed over the bed surface. Heaters kept the tem- peratures of both the water and air equal to that of the granular material.
