| Abstract: | Detergent Production in Air Vortex Mixer A method for the production of washing and cleansing materials by spraying of detergents on sodium tripolyphosphate and other carriers is described. It is found that in an air vortex mixer sodium tripolyphosphate with a high phase-I content is best suited for the purpose. Because of the high phase-I content, the removal of water from the aqueous detergent takes place so fast that the heat of hydration is liberated in the air vortex mixer and the continuous stream of the cold air through the mixer is immediately carried off. The method allows the production of detergents with bleaching agents in one step. The guiding formulations for the production of detergents are given. |
