1. A method for spray drying plasma from an amount of donor plasma using 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, a plasma source providing a plasma and a pressurized aerosol gas source providing a pressurized aerosol gas, the method comprises:
drying the amount of donor plasma in a time period, said drying step is performed with the spray drying disposable device comprising:
A) the spray drying head comprising:
i) a spray dry nozzle assembly in fluid communication with the plasma source and the pressurized aerosol gas source, wherein, when in use, the pressurized aerosol gas flows in a vortex pattern, wherein, when in use, the pressurized aerosol gas atomizes the plasma entering the drying chamber to obtain atomized plasma droplets;
ii) a drying gas inlet in communication with the drying gas source;

B) the drying chamber, attached to the spray drying head, wherein, when in use, atomized plasma droplets evaporate when contacting the drying gas emitted from the spray drying head to thereby obtain dried plasma particles and humid air;
C) a capture filter, residing in the drying chamber, wherein, when in use, the capture filter captures the dried plasma particles and allows the humid air to pass; and
D) a gas outlet, wherein said gas outlet is attached to an exhaust port of the spray drying system during operation, wherein, when in use, the humid air flows through the gas outlet wherein the time period for drying the donor plasma ranges from about 20 minutes to about 60 minutes.
