1. A method of controlling the moisture content of a spray dried plasma, the method comprising:
a) providing: i) plasma, and ii) a spray drying apparatus, comprising, a mechanism for aerosolizing the plasma, a mechanism to deliver drying gas at a controlled rate, a drying chamber, a collection chamber and a sensor for measuring exhaust gas temperature as it emerges from the drying process; b) operating the spray drying apparatus to produce a moisture controlled spray dried plasma, said operation comprising controlling the moisture content of the spray dried plasma collected in the collection chamber by measuring the exhaust gas temperature with the sensor for measuring exhaust gas temperature and adjusting the flow of the drying gas based on the exhaust gas temperature wherein the flow of the drying gas is increased to increase the exhaust gas temperature and decrease the moisture content of the spray dried plasma; and the drying gas flow is decreased to decrease the exhaust gas temperature and increase the moisture content of the spray dried plasma, thereby producing a moisture controlled spray dried plasma, wherein the moisture content of the moisture controlled spray dried plasma is approximately 4 w/w % to approximately 10 w/w %. |
