Effects of process variables on the powder yield of spray ...

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.

Advantages and challenges of the spray-drying technology ...

Generally, the yield% of spray-drying at laboratory scale with conventional spray-dryers is not optimal (20-70%) due to the loss of product in the walls of the drying chamber and the low capacity of the cyclone to separate fine particles (2 μm). Aiming to overcome this crucial drawback in early development stages, new devices that enable the ...

Freeze Drying vs Spray Drying: is it essentially quality ...

It is widely accepted the costs associated with spray drying are less than those of of freeze drying, which has made the technique one of interest for certain markets; and, being more open to larger throughput potentials, spray drying can be deemed a ‘continuous process’, unlike the batch format associated with freeze drying.
