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 an aqueous or non-aqueous surfactant, and coating the surfactant with fine powders having a diameter from 0.1 to 500 microns, in the mixer to obtain irregular shape granules and excessive fine powders, and (b) granulating the agglomerates in one or more fluidizing apparatus. The process can also comprise further step (a'), i.e., spraying finely atomized liquid onto the first agglomerates in a mixer, between step (a) and step (b).
Description
Invention field
The present invention relates generally to produce the non-tower method of granular detergent composition.More particularly, the present invention relates to a kind of continuous production method, in the production process of this method, produce detergent agglomerate by adding tensio-active agent and coated material in a series of mixing tanks.Method of the present invention can be produced free-pouring detergent composition, and its density can be regulated in the wide region of consumer wants, and described product can carry out market sale.
Background of invention
In recent years, the product that receives much concern in the laundry detergent industry is the concentrated type product that has than low dosage volume.For facility is produced these so-called low dosage washing composition, people have carried out multiple trial to produce the higher washing composition of volume density, and for example, density is 600g/l or higher.Because this low dosage washing composition can be saved resource and small packages form that can more convenient human consumer is sold, thereby its demand increased day by day.Yet in fact, modern Betengent product should " concentrating " to which kind of degree be still uncertain on earth.In fact, many human consumers', particularly developing country human consumer still more is ready to adopt the high dosage washing composition in its each laundry operations.
In general, the method for preparing washing agent particle or powder comprises two kinds of main types.First method relates in spray-drying tower carries out spraying drying to the aqueous detergent slurries, produces porous detergent particles (for example, be used for low density detergent composition the tower step arranged).In the second method, various detergent components do are mixed, after this, use tackiness agent to make its agglomeration, produce the high density detergent composition agglomeration technique of high density detergent composition (as be used for) such as nonionogenic tenside or anion surfactant.In above-mentioned two kinds of methods, the important factor of controlling formed detergent particle granule density is described coating of particles, porosity and size distribution, the density of various raw materials, the shape of various raw materials and they chemical constitution separately.
Attempt to provide the method that can increase detergent particles or powder density in this area always.Particularly make spray-dired particle densification by back tower treating processes.For example, one of means relate to carries out batch production, wherein, and at Marumerizer
In will comprise the spraying drying of tripoly phosphate sodium STPP and sodium sulfate or granulation detergent powder carry out densification and balling-up is handled.Substantially horizontal, the coarse and rotatable worktable of described equipment bag meeting, this worktable is positioned at the circular cylindrical shell of perpendicular and inner wall smooth and is its substrate.Yet,, be not suitable for the scale operation detergent powder because this process mainly is a kind of periodical operation process.At last, people also attempt to provide the density of the detergent particles of a kind of continuation method to increase " product behind the tower " or spraying drying and cross.Usually, these class methods need be pulverized or grind particulate first device and increase second of pulverizing back pellet density by agglomeration and install.Although these methods are by handling or densification " product behind the tower " or spray-dried granules have reached the increase of needed density,, when the application step that is provided with subsequently, be restricted aspect the raising ability of surfactivity degree.In addition, by " tower aftertreatment " method handle or densification from considering economically and uneconomical (cost is very high), and production process complexity.And then all aforesaid methods all relate generally to and carry out densification or carry out spray-dried granules.At present, a large number of and equal material of type is subject to spray-drying process in the washing composition production process.For example, in the detergent composition that forms, will be difficult to realize the tensio-active agent high-content, and also be difficult to produce washing composition in more effective mode expediently.Therefore, still wish to find a kind of method that is not subjected to the production detergent composition of conventional spray drying technology restriction.
For this reason, also proposed in this area variously must carry out agglomerant method to detergent composition.For example, by being mixed in mixing tank, zeolite and/or layered silicate make the detergent builders agglomeration to form free-pouring agglomerate.The explanation of this trial hint, aforesaid method can be used for producing detergent agglomerate; But they can not provide a kind of mechanism, adopt described mechanism can make pasty state, liquid and dry-matter shape detergent raw material agglomerate into easily crisp, free flowing detergent agglomerate effectively.
Thereby, still needing to seek a kind of agglomeration method (non-tower method) that is used for direct by detergent raw material continuous production high density detergent composition in this area, preferred density can realize by regulating processing conditions.Equally, still wish to find a kind of more effective, have more adaptability and more economical method, so that the scale operation washing composition, can (1) make the final densities of finished product detergent composition should have more the more poly-handiness of adding that handiness and (2) make the especially aqueous detergent component of various detergent component.
Following reference relates to the process that makes spray-dired particle densification: Appel etc., and US 5,133,924 (Lever); Bortolotti etc., US 5,160,657 (Lever); Johnson etc., GB 1,517,713 (Unilever); And Curtis, EP 451,894.
Following reference relates to by agglomeration produces washing composition: Beujean etc., WO93/23,523 (Henkel); People such as Lutz, US4,992,079 (FMC Corp.); People such as Porasik, US4,427,417 (Korex); Beerse etc., US 5,108,646 (Procter ﹠amp; Gamble); Capeci etc., US 5,366,652 (Procter ﹠amp; Gamble); Hollingsworth etc., EP 351,937 (Unilever); Swatling etc., US5,205,958; People such as Dhalewadikar, the open WO96/04359 (Unilever) of international application.
For example, WO93/23,523 (Henkel) disclose a kind of method, this method comprises by low speed mixer carries out pre-agglomeration, used the further agglomeration of high-speed mixer again, and obtained high density detergent composition, the particle grain size that said composition is lower than 25wt% surpasses 2mm.US4 has described among 427,417 (Korex) and has been used for agglomerant continuation method, and this method can reduce caking and cross the agglomeration phenomenon.
