Description

Make the method for cleaning composition with non-tower process
Invention field
The present invention relates generally to produce the non-tower method of granular detergent compositions.More specifically, The present invention be directed to a kind of successive method, this method comprises and adds tensio-active agent and coat upward material production detergent agglomerate in a series of mixing tank.This method is produced the free-pouring cleaning composition of a kind of energy, and its density can be adjusted in the needed wide range of human consumer, and said composition can be sold on market.
Background of invention
Quite interested in detergent for washing clothes " densification ", that the use volume is little in detergent industry recently.In order to promote the production of these so-called low consumption washing composition, to produce high bulk density for example density be that washing composition more than the 600g/l has carried out many explorations.Because low consumption washing composition is saved resource, and can with to the human consumer more easily small packages sell, so at present it is in great demand.Yet the compactness extent that modern Betengent product need reach does not in fact also solve.In fact, many human consumers', particularly developing country human consumer still likes bigger consumption in their laundry processes separately.
The method of preparing washing agent particle or powder generally has two big classes.First kind method is included in the aqueous washing composition slurry of spraying drying in the spray-drying tower, produces very loose detergent particles (tower process of for example production low density cleaning composition).In second class methods, with various detergent ingredients dry blending, adopt binding agent then, tensio-active agent for example non-ionic type or anionic earlier, make their agglomeration, produce highdensity detergent composition (for example producing the agglomeration method of high density detergent).In above two kinds of methods, the important factor of the detergent particle granule density that control is produced is described coating of particles, porosity and size-grade distribution, the density of various raw materials, the shape of various raw materials and chemical constitution separately thereof.
For the method that improves detergent particles or powder density is provided, many trials in this area, have been carried out.Especially notice and adopt (post tower) behind the tower to handle compaction spray-dried granules.For example, a kind of process of attempting using an interruption is arranged, in this process, make the detergent powder densification of the spray-dired or granulation that contains tripoly phosphate sodium STPP and sodium sulfate, and make its nodularization in a Marumerizer .In this equipment, comprise that one is level, coarse rotating disk basically, it is positioned at one is the bottom of slick cylinder on vertical, the wall basically.Yet this method is the method for an interruption basically, thereby is not suitable for producing on a large scale detergent powder.Recently, for forming the continuation method that improves " behind the tower " drying or spray-dried detergent pellet density, other trials have been carried out.These methods need be pulverized or grind the particulate primary equipment usually and improve by the second set of pulverized particles density by nodulizing.Though these methods are handled " behind the tower " drying or spray-dired particle or made its densification, have reached the requirement that improves density, do not have encapsulation steps subsequently, the ability that makes their improve tensio-active agent effective content is restricted.In addition, from the viewpoint of economics (investment cost height) and complicated operation degree, it is disadvantageous adopting " behind the tower " processing or densification.And all above-mentioned methods are mainly at densification, or in other words, are at handling spray-dired particle.In the production of granulated detergent, the relative populations and the kind of the material of process spray drying treatment are restricted at present.For example in the cleaning composition of producing, obtain high-load tensio-active agent and be difficult to, this is the principal element that promotes to produce with more efficient methods washing composition.Therefore, need a kind of method that can not be subjected to the production cleaning composition of restriction that conventional spray drying technology adds.
Also there are many open source informations that carry out the method for cleaning composition agglomeration process for this purpose this area.For example mixed zeolite and/or lamellated silicate in mixing tank carry out the agglomerant trial of scrubbed component, so that make free-pouring agglomerate.Though these trials show, their method can be applied to produce detergent agglomerate, but they do not propose and can effectively pasty state, liquid be agglomerated into mechanism crisp, the free-pouring detergent agglomerate of energy with the exsiccant detergent raw material.
Therefore, this area also needs a kind of method (non-tower method) of continuous production high density detergent composition agglomerate, and its high-density is directly produced by the washing composition original composition, can preferably reach this density by regulating working condition.Yet needing a kind of (1) can adapt to the final densities of final product composition having and (2) and can adapt to several dissimilar detergent ingredients (particularly Ye Tai composition) in the adition process, more effective, more flexible and more economical method is so that produce washing composition on a large scale.
