Low temperature spray drying of carrier-free compositions

A spray drying process for drying a spray dryable liquid composition to a spray dried powder, wherein the spray dryable liquid composition contains no carrier, the process comprising:

• providing the spray dryable liquid composition at a solids concentration of at least 45% by weight but not exceeding 80% by weight, based on total weight of the spray dryable liquid composition;
• atomizing the spray dryable liquid composition to generate an atomized spray of liquid particles of the spray dryable liquid composition into a spray drying chamber;
• flowing a stream of drying fluid at a temperature not exceeding 100° C. into the spray drying chamber for flow through the spray drying chamber, to contact the spray of liquid particles therein for drying of the liquid particles to form the spray dried powder;
• and
• discharging from the spray drying chamber effluent drying fluid and the spray dried powder dried by contact with the drying fluid in the spray drying chamber,
• wherein said atomizing is carried out so that the atomized spray of liquid particles of the spray dryable liquid composition comprise droplets of the spray dryable liquid composition having a droplet size in a range of from 10 to 300 μm.
