    Abstract: A non-tower process for continuously preparing granular detergent composition having a low density, preferably about 300 g/l to about 600 g/l is provided. The process comprises the steps of (a) (i) dispersing an aqueous or non-aqueous surfactant, and (ii) coating the surfactant with fine powders having a diameter from 0.1 to 500 microns, in the mixer which is operated under certain conditions to obtain irregular shape granules and excessive fine powders and, (b) spraying on finely atomized liquid to the irregular shape granules and excessive fine powders from step (a), in a mixer which is operated under certain conditions to bind the excessive fine powders onto the irregular-shaped granules.

  • Patent number: 6150323
    Abstract: A non-tower process for continuously preparing granular detergent composition having a density of at least about 600 g/l is provided. The process comprises the steps of (a) dispersing a surfactant, and coating the surfactant with fine powder in a mixer, wherein first agglomerates are formed, (b) thoroughly mixing the first agglomerates in a mixer, wherein second agglomerates are formed, and (c) granulating the second agglomerates in one or more fluidizing apparatus. The process can also comprise further step (b'), i.e., spraying finely atomized liquid onto the second agglomerates in a mixer, between step (b) and step (c).

  • Patent number: 6140302
    Abstract: A process for the production of anionic surfactant granules comprising the steps of:A) Neutralizing an acidic anionic surfactant with a base in a horizontal thin-layer evaporator or thin-layer dryer; andB) Drying the resulting neutralized anionic surfactant in the evaporator or dryer to form surfactant granules; wherein the acidic anionic surfactant and the base taken together have a solids content such that the total quantity of water in the evaporator or dryer at no time exceeds about 15 % by weight and wherein the neutralization and drying are carried out in countercurrent flow with air or an alkaline gas stream at a temperature in the range of from about 120 to about 130.degree.

  • Patent number: 6136777
    Abstract: A non-tower process for continuously preparing granular detergent composition having a density of at least about 600 g/l is provided. The process comprises the overall steps of: (a) dispersing a surfactant, and coating the surfactant with fine powder in a mixer, wherein first agglomerates are formed; (b) spraying finely atomized liquid onto the first agglomerates in a mixer, wherein second agglomerates are formed; and (c) granulating the third agglomerates in one or more fluidizing apparatus. The process is improved by further step (b'), by thoroughly mixing the second agglomerates in a mixer, between step (b) and step (c), wherein, in step (b'), choppers are used to reduce the amount of oversized agglomerates.
