Abstract

A process for the production of pourable and free flowing granules of materials or mixtures thereof which are suitable for use as wetting agents, detergents or cleaning products wherein an aqueous solution or suspension of the wetting agents, detergents or cleaning products is dried using a hot gas stream of superheated steam. Drying is terminated before the granules are damaged by heat, and the hot gas stream is freed from entrained particles of the materials by means of filters.
