Process for manufacture of detergent powder |
摘要 |
A process for manufacturing detergent powder containing heat-sensitive components is disclosed. The process involves preparation of two separate crutcher slurries, one containing the relatively heat-stable components which is sprayed in a conventional manner and a second containing heat-sensitive components which is sprayed into the spray-drying tower at a level lower than the level at which the drying air is injected. Desirably the second slurry is sprayed in a direction which includes an upward component, so as to lengthen the pathway of the sprayed droplets.
