Beschreibung
Zusammenfassung:	The present invention is to a process for preparing a spray- dried detergent powder comprising: (a) forming an aqueous detergent slurry in a mixer; (b) transferring the aqueous detergent slurry from the mixer to a pipe leading through a first pump and then through a second pump to a spray nozzle; (c) contacting a liquid detergent ingredient having a viscosity of less than 2 Pa.s to the aqueous detergent slurry in the pipe after the first pump and before the second pump to form a mixture; (d) spraying the mixture through the spray nozzle into a spray -drying tower; and (e) spray- drying the mixture to form a spray -dried powder , wherein a nitrogen -rich gas is introduced between the first and second pumps.
