Abstract (en)
[origin: US5516447A] PCT No. PCT/EP92/01831 Sec. 371 Date Feb. 22, 1994 Sec. 102(e) Date Feb. 22, 1994 PCT Filed Aug. 11, 1992 PCT Pub. No. WO93/04162 PCT Pub. Date Mar. 4, 1993.A process for the production of washing- and cleaning-active surfactant granules containing 60 to 70% by weight of surfactant and having an apparent density above 500 g/l, wherein a formulation containing a non-surface-active liquid component and having a liquid to paste-like form under normal pressure at temperatures of 20 DEG to 40 DEG C. is introduced to a fluidized bed and granulated and, at the same time, totally or partially freed from the non-surface-active liquid compound, optionally with addition of an inorganic or organic solid, and wherein the granules are discharged from the fluidized bed via a grading step by a countercurrent air-stream which is adjusted so that only particles above a predetermined size are removed from the granules.
