Abstract
A spray drying process and apparatus for drying a spray dryable liquid composition to a spray dried powder is described, in which the spray dryable liquid composition contains no carrier. The spray dryable liquid composition is processed at a solids concentration not exceeding 80% by weight, based on total weight of the spray dryable liquid composition, being atomized to generate an atomized spray of liquid particles of the spray dryable liquid composition into a spray drying chamber, in which the atomized spray is contacted with a stream of drying fluid flowed at temperature not exceeding 100° C. into the spray drying chamber, to form the spray dried powder.
