Patent number: 6156719Abstract: 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.Type: GrantFiled: April 1, 1999Date of Patent: December 5, 2000Assignee: The Procter & Gamble CompanyInventors: Angela Gloria Del Greco, Manivanan Kandasamy

Patent number: 6150323Abstract: 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).Type: GrantFiled: April 1, 1999Date of Patent: November 21, 2000Assignee: The Procter & Gamble CompanyInventors: Angela Gloria Del Greco, Wayne Edward Beimesch, Manivannan Kandasamy

Patent number: 6143711Abstract: 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 having a diameter from 0.1 to 500 microns in a mixer fitted with choppers, and (b) granulating the agglomerates in one or more fluidizing apparatus, wherein finely atomized liquid is sprayed onto the first agglomerates in a mixer between step (a) and (b).Type: GrantFiled: April 1, 1999Date of Patent: November 7, 2000Assignee: The Procter & Gamble CompanyInventors: Angela Gloria Del Greco, Wayne Edward Beimesch

Patent number: 6136772Abstract: The present invention relates to enzyme-containing granules comprising (a) an enzyme and (b) a core which intrinsically is capable of absorbing at least 5% w/w (based on the weight of the core) of water and to processes for the production of such granules comprises (a) contacting absorbent cores, capable of absorbing at least 5% w/w (based on the weight of the core) of water, with a liquid medium, such as an aqueous medium, containing an enzyme in dissolved and/or dispersed form, the amount of the liquid medium employed being such that substantially no attendant agglomeration of the resulting product occurs; and (b) at least partially removing volatile components of the liquid medium from the resulting product.Type: GrantFiled: May 14, 1997Date of Patent: October 24, 2000Assignees: Novo Nordisk A/S, Novo Nordisk Bio IndustrialInventors: Joao F.
