A survey is presented of various processes and spray drying installations for obtaining skimmed milk powders with desired qualities. The spray dryers discussed are: spray dryer with pneumatic conveying system, two‐stage drying system, spray dryer with cooling bed, and spray dryer with straight‐through instantizer. The rewet agglomeration process is also described. The second part deals with the most important final product properties (moisture, bulk density, and solubility index) and with the parameters controlling them. In the third part the possibilities are discussed of saving energy and reducing stockloss. Two types of heat recuperators (air‐to‐air and air‐to‐liquid‐to‐air) and wet scrubber are described.
