Beschreibung
Zusammenfassung:	A method is provided for spray-drying large volumes of a detergent slurry in a spray-drying tower which comprises spraying at least a portion of the slurry, cocurrently with air having a specified temperature and velocity range, through uniformly spaced atomizing nozzles into a cylindrically shaped drying zone. Any remaining balance of the slurry is sprayed countercurrently into the drying zone at higher levels in the spray tower. Apparatus is provided for practicing this process. Granular detergent compositions having improved physical properties are also disclosed.
