The Effect of Inlet Temperature on the Wall Temperature Behavior of Salt Powders Produced by Spray-Drying

This research is concerned with the experimental study of the wall temperature behavior of salt powders in the spray-drying process under various inlet temperatures. The results are presented and discussed in terms of the temperature profiles within two sections of the drying chamber that consists of cylindrical and conical sections. Firstly, the temperature profiles of cylindrical section have shown that the behavior from the steps of spraying air, water, and solution before has lead to a steady state process. Finally, the wall temperature distribution at each elevation has shown a statistically significant difference. In our future work, the wall temperature behavior will be compared with the wall deposition flux in order to determine a prediction equation that can be applied to manage the deposition problem in the spray-drying process stage.
