1. A spray drying disposable device, having a spray drying head and a drying chamber, for use in a spray drying system having a drying gas source providing a drying gas that, when in use, communicates with the drying chamber, a liquid source providing a liquid, and a pressurized aerosol gas source providing a pressurized aerosol gas, the spray drying disposable device comprising:
A) the spray drying head comprising:
i) a spray dry nozzle assembly, wherein, when in use, is in fluid communication with the liquid source and the pressurized aerosol gas source, wherein, when in use the pressurized aerosol gas flows in a vortex pattern and atomizes the liquid entering the drying chamber to obtain atomized liquid droplets;
ii) a plenum having a drying gas inlet in communication with the drying gas source, wherein, when in use, the drying gas resides in the plenum with uniform air pressure;
iii) a baffle plate forming a floor of the plenum having one or more drying gas jets, wherein the one or more drying gas jets provide the drying gas to the drying chamber, wherein the plenum further comprises a baffle filter, through which the drying gas flows; wherein the nozzle assembly is at the baffle plate;
B) the drying chamber, attached to the baffle plate, wherein, when in use, the atomized liquid droplets evaporate when contacting the drying gas emitted from the one or more drying gas jets to thereby obtain dried particles and humid air, wherein the dried particles are captured and the humid air is allowed to pass.
