Apr 01, 2005 The drying air flow rate, v da, determines both of the rate of enthalpy throughput (kcal/h) of the spray-dryer and the droplet/particle residence time within the spray-dryer. Table 4 shows that reducing v da produces a linear decrease in the powder yield. There was a corresponding visual increase in deposit on the inside wall of the drying chamber.
