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.

Abstract: The disclosure relates to ultrahigh efficiency spray drying systems and processes, utilizing induction of localized turbulence in a drying fluid flow stream to produce spray dried product, having particular utility for low temperature spray drying operations. In a specific implementation, a method of processing a spray dryable liquid composition to form a spray dried product includes the steps of: generating a spray of the spray dryable liquid composition; contacting the spray of spray dryable liquid composition in a spray drying contact zone with a stream of primary drying fluid; injecting pressurized secondary drying fluid into the stream of primary drying fluid in the spray drying contact zone at multiple loci thereof to provide localized turbulence at said multiple loci; and recovering the spray dried product from the spray drying contact zone.
