Abstract
Described herein are devices and techniques for spray drying a fluid to produce a dried powder. Assemblies include a spray drying head attachable to a gas supplier and a liquid sample, such as a standard unit of blood product. The spray drying head can be adapted to provide an aerosolized flow of liquid sample exposed to a drying gas. The assembly also includes a drying chamber adapted to separate the aerosolized flow of liquid sample into a dried powder and humid air. The assembly can be disposable, provided in a sterilized kit and having simplified attachments allowing quick connect and disconnect from the gas and liquid sample. Separation of the powder from the humid air exiting the drying chamber occurs within a filtered collection bag. In some embodiments, one or more of the drying chamber and collection bag are formed form a thin-walled, collapsible material.
