Low spray drying method in order the detergent powder which density and spraying of the builder and flood solubility is dried low to produce

摘要

As for this invention, as for the spray drying detergent powder, the anionic characteristic detergent surface active agent and 0 weight % - 10 weight % the zeolite builder and, and 0 weight % - 10 weight % including the phosphorus acid builder either, as for this method, (a) 30 weight % - 60 weight % the water and, and 40 weight % - 70 weight % including the non water substance and the mineral element and the organic component to produce the water slurry which is suited for the spray drying which becomes in regard to the spray drying method for producing the spray drying detergent powder which possesses the bulk density below 426g/L, as for the non water substance, including or, inorganic for the organic componentWeight ratio of the component is inside the range of the 0.3:1 - the 5:1, (b) slurry spraying is done in the spray drying tower, including each process, it is something which becomes, the occasion where it introduces to the spray drying tower, temperature of slurry is inside the range of the 65 - the 140 , at the same time exhaust gas temperature of the spray drying tower is inside the range of the 70 - the 120 , it regards method.
