Verfahren zur kontinuierlichen Herstellung eines granularen Wasch und/oder Reinigungsmittels

摘要

Non-dusting, non-greasing granulated washing and cleaning agents which do not tend to get stuck or glued together, which have a high apparent density and which contain substantial amounts of anionic and non ionic surfactant should be produced. For that purpose, a two-stage granulation is carried out in two successively arranged mixers/granulators. In a first low-speed mixer/granulator 40 to 100 % by weight, in relation to the total amount of the solid and liquid components used, of the solid and liquid components are pregranulated and in a second, high-speed mixer/granulator, the pre-granulate from the first step of the process is if required mixed with the remaining solid and/or liquid components and converted into a granulate. The proportion of grains having more than 2 mm diameter is lower than 25 % by weight. Granulates having a relatively low proportion of coarse grains are thus produced and the apparent density of the granulates can be appropriately adjusted.
