<p>Hygroscopic powders, especially fat-containing milk products, are cooled by being fluidized in cooling air. Dehumidification of the drying air is omitted and overdrying prior to cooling to compensate powder rehumidification during cooling is avoided by using a closed cycle cooling in which the spent cooling air after efficient dust removal and re-cooling is used as cooling and fluidizing air.</p> |
