Abstract (en)

[origin: WO0155284A2] The invention relates to a method for producing surfactant granulates. According to the invention, a pourer plate subjects a stream of an aqueous surfactant preparation to vibrations which induce it to drip, and the drops are guided against a gaseous desiccant which vaporizes the water portions thus drying the granulates.
