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 having a diameter from 0.1 to 500 microns, in a mixer, wherein first agglomerates are formed, (b) thoroughly mixing the first agglomerates in a mixer, wherein second agglomerates are formed, and (c) spraying finely atomized liquid onto the second agglomerates in a mixer.
Description
Invention field
The present invention relates generally to produce the non-tower process of shot detergent composition.More particularly, The present invention be directed to a kind of continuation method of producing detergent agglomerate by material in a kind of tensio-active agent of adding in a series of mixing tanks and the coating.This method is produced a kind of detergent composition of good fluidity, and the density of said composition can be according to human consumer's needs and in very large range regulated, and this detergent composition can be sold on market.
Background of invention
Recently detergent industry is for " closely knit ", thereby the cloth-washing detergent of low consumption has sizable interest.For the production of the washing composition that promotes these so-called low consumptions, the positive now many-sided washing composition of producing high bulk density by every means of people, for example production density is 600 grams per liters or higher washing composition.Low consumption washing composition sells well at present very much, because they are saved resource and can sell with more convenient human consumer's small packages., modern Betengent product is needing " compacting " which kind of degree to be still uncertain in nature.In fact, many human consumers', particularly many developing countries human consumer still has a preference for a kind of washing composition of higher dosage in their laundry operations separately.
Preparing washing agent particle or powder method that two kinds of main types are generally arranged.First type method comprises carries out spraying drying with the aqueous detergent slurry in spray-drying tower, with the detergent particles of producing high porosity (for example, low density detergent composition have tower process).In second type method, various washing composition batchings are done and are mixed, detergent component carries out agglomeration with for example non-ionic or anionic tensio-active agent of binding agent then, to produce high density detergent composition (for example agglomeration process of high density detergent composition).In two kinds of above-mentioned methods, the important factor of controlling final resulting detergent particle granule density is described coating of particles, porosity and size-grade distribution, various raw-material density, various raw-material shapes and starting material chemical constitution separately.
In the method that the density that can increase detergent particles or powder is provided, this area had been carried out many trials.Pay special attention to utilize the back tower to handle and make spray-dired particle densification.For example, a kind of trial has comprised a kind of discontinuous method, with this method, contains detergent powder densification and spheroidization in a Marumerizer of the spray-dired or granulation of tripoly phosphate sodium STPP and sodium sulfate.This equipment is included in and is positioned at perpendicular, in the cylinder of smooth-walled and bottom substantially horizontal, shaggy rotating disk.This method comes down to a discontinuous method, therefore is unsuitable for the scale operation detergent powder.People have carried out other trial recently, so that the successive method to be provided, are used for increasing " back tower " or spray-dried detergent particulate density.In typical case, such method needs primary equipment and second set, and primary equipment makes particle pulverize or grind, and second set utilizes nodulizing to increase the density of pulverized particles.Though these methods are by to the processing of " back tower " or spray-dried granules or the needed increase of densification realization density, these methods are being restricted aspect the ability that further improves the surfactant activity component concentration without subsequently encapsulation steps.In addition, from the complicacy of economic angle (high capital cost) and operation, back tower is handled or densification is not favourable.Moreover the target of above-mentioned method mainly all is at the particle densification that spraying drying is crossed or the processing treatment of carrying out other.In the process of producing detergent particles, the relative populations and the type that participate in the raw material of spray-drying process all are restricted recently.For example, in final resulting detergent composition, be difficult to obtain the high surface agent content, this characteristics are impelled in a kind of more effective mode and are produced washing composition.Therefore, need a kind of method, can not be subjected to the added restriction of conventionally spray-dried technology to produce detergent composition.
This area discloses many methods with the detergent composition agglomeration process for this reason.For example, attempt in a mixing tank, zeolite and/or layered silicate being mixed, make the detergent component agglomeration, to form free-pouring agglomerate.Although it is so trial proposes to produce detergent agglomerate in this way, does not but propose a kind ofly pasty state, detergent raw material liquid and the dry material shape effectively to be gathered into mechanism crisp, free-pouring detergent agglomerate.
Therefore, this area still need a kind of can continuous production agglomeration (non-tower) technology of detergent composition, this washing composition has the high-density that can directly obtain with the washing composition original ingredient, and can preferably obtain this density by regulating processing condition.Still need so a kind of more effective, more flexible and more economical method in addition, produce washing composition on a large scale in several washing composition batching (particularly liquid dispensing) introducing processes to impel under the situation that can have handiness and (2) that handiness is arranged in the limiting density of (1) final composition.
Following reference is about making the spray-dried granules densification: people's such as Appel United States Patent (USP) 5,133,924 (Lever); People's such as Bortolotti United States Patent (USP) 5,160,6571 (Lever); People's such as John-Son English Patent 1,517,713 (Unilever); European patent application 451,894 with Curlis.
Following document is about produce washing composition by nodulizing: people such as Beujean openly apply for WO 93/23,123 (Henkel), people's such as Lutg United States Patent (USP) 4,992,079 (FMC Corp.); People's such as Porasik United States Patent (USP) 4,427,417 (Kokex); People's such as Beerse United States Patent (USP) 5,108,646 (Procter﹠amp; Gamble); People's such as Capeci United States Patent (USP) 5,366,652 (Procter﹠amp; Gamble); People's such as Hollingsworth european patent application 351,937 (Unilever); People's such as Swatling United States Patent (USP) 5,205,958; People such as Dhalewcadikar openly apply for WO 96/04359 (Unilever).
For example, the method that disclosed WO 93/23,523 (Henkel) is introduced comprises: utilize the pre-nodulizing and the further agglomeration step of utilizing super mixer of slow-speed mixer less than 25% highdensity detergent composition in order to obtain the particle weight of particle diameter above 2 millimeters.United States Patent (USP) 4,427,417 (Korex) have described the successive agglomeration method, and this method can reduce caking and oversize agglomerate.
Not having in the prior art a kind ofly can provide whole advantage of the present invention and strong point.
