    摘要: A free-flowing washing powder of low specific gravity (powder density 300 to 500 g/l) and containing large quantities of nonionic surfactants is produced by spray-drying an aqueous suspension containing on the spray-dried basis (A) from 15 to 30% by weight of nonionic tensides, (B) from 8 to 18% by weight of sodium silicate, (C) from 25 to 55% by weight of finely crystalline zeolite, (D) from 0 to 25% by weight of sodium tripolyphosphate, (E) no more than 3% by weight of soap and synthetic anionic tensides, and from 35 to 50% by weight of water. The suspension, which has a temperature of from 75.degree. C. to 90.degree. C., is sprayed through nozzles into a drying zone under a pressure of from 35 to 100 bar. The drying gas flowing in countercurrent has an entry temperature of from 160.degree. C. to 240.degree. C. and an exit temperature of from 80.degree. C. to 95.degree. C. The spray-dried product contains from 9 to 16% by weight of water which is removable at a drying temperature of 130.degree. C.

    摘要: A spray-dried, high-sudsing detergent granulate is disclosed having a bulk density of not more than 450 gm/l and a high content of anionic tensides, which is characterized by a granule structure resistant to mechanical and climatic influences. The detergent granulate contains a tenside component of alkylbenzene sulfonates and, possibly, fatty alcohol sulfates, a builder component of sodium tripolyphosphate, finely crystalline sodium aluminosilicate (zeolite NaA) and sodium silicate. For the preparation, an aqueous slurry is sprayed in spray-drying equipment. The obtained spray-dried product has a porous granule structure with a mean granule size of 0.4 to 0.8 mm. The bulk density is preferably in the range from 250 to 400 gm/l.
