Abstract
A process for manufacturing a group of detergent granules which includes a step of granulating powdery raw materials for a detergent in a rotating mixer, wherein the granulation of the powdery raw materials is conducted with a foamed anionic surfactant composition sprayed in the rotating mixer through a multi-fluid nozzle. By this process, a group of detergent granules having a medium or low bulk density can be obtained in a high yield. The group of detergent granules thus obtained exhibits high solubility.
Description
Technical field
The present invention relates to use the detergent particles group's of container rotary mixing machine, the foam of anionic surfactant compositions, many fluid tips manufacture method.
Background technology
Now in commercially available washing composition, rough classification has high volume density type washing composition (being greater than 690g/L), middle volume density type washing composition (400～690g/L), low volume density type washing composition (250g/L above and be less than 400g/L), liquid washing agent etc.For example in Japan, use high volume density type washing composition, but in areas such as asia and ocenia or Europe, the demand of the low volume density type of centering washing composition is also many more.
From the viewpoint of economy, environmental response, as not using spray-dired manufacture method, disclose the manufacture method of using the detergent composition of aniorfic surfactant by non-spray-drying process.In patent documentation 1, disclose by surfactant paste and for dried detergent materials high-speed mixer/middling speed mixing machine/drying machine manufacture continuously the method for detergent composition.In patent documentation 2, while disclose, in high-speed mixer/middling speed mixing machine/setting device, make particulate recirculation manufacture continuously the method for detergent composition surfactant paste and dried detergent raw material.
Yet, in the method for making of patent documentation 1, be difficult to regulate granularity, in addition, in the method for making of patent documentation 2, in order to carry out the adjusting of granularity, use the method for making of particulate recirculation, from but the low manufacture method of productivity.Therefore, seek the method for making that yield more simply obtains the detergent particles group of necessary granularity well.Further, these patent documentations are all to provide the method for the volume density that increases detergent particles group, the detergent particles group's of low volume density manufacture method in being not suitable as.
In addition, in patent documentation 3, as reducing spray-dired use or not using spray-dired manufacture method, disclose by the foam of tensio-active agent being imported to the manufacture method of the surfactant granules in mixing machine.
Yet, in the manufacture method of patent documentation 3, be not enough to as obtain detergent particles group's method for making with good yield.

Summary of the invention
The present invention relates to a kind of detergent particles group's manufacture method, described detergent particles group's manufacture method has the container of use rotary mixing machine by the operation of detergent use powder raw material granulation, and described detergent particles group's manufacture method for carrying out by multithread body nozzle spray the foam of anionic surfactant compositions the granulation of this detergent use powder raw material in this container rotary mixing machine.
Embodiment
The present invention relates to provide with do not use spray-dired method with good yield manufacture contain anion surfactant in detergent particles group's the method for low volume density.
By detergent particles group's of the present invention manufacture method, can produce the effect of the detergent particles group of low volume density in can obtaining with good yield.In obtaining like this, the detergent particles group of low volume density also has the high deliquescent effect of demonstration.
One of the present invention is characterised in that, uses container rotary mixing machine to carry out the granulation of detergent use powder raw material.
In general, while using container rotary mixing machine to carry out granulation, can make powder flow equably, in addition, due to the mixed organization that takes up and cause landing to fall due to deadweight with cause particle due to rotation, thereby suppressed to put on the shearing force on powder.Therefore, can say and use the prilling process that the prilling process of described mixing machine is non-densification.In addition, if just can not carry out granulation by force owing to adding anionic surfactant compositions in the described mixing machine tackiness when contacting with powder to, therefore, need to when contacting with powder, show tackiness.If such anionic surfactant compositions is used as to single fluid nozzle or the pipe arrangement of common supply method, be supplied to container rotary mixing machine, can find to be difficult to make in mixing machine the liquid component of supplying with to disperse equably, due to the large liquid piece of part generation, easily form the tendency of thick particle.
At this, many fluid tips of use two-fluid spray nozzle etc., the foam that shows adhesive anionic surfactant compositions by spraying when contact with powder is supplied in container rotary mixing machine, is surprised to find that the also granulation equably of formation that can suppress big particle.This is considered to due to by using many fluid tips to make in advance the foam of such anionic surfactant compositions become fine drop, even if thereby in container rotary mixing machine, also can reach the high dispersive of the foam of anionic surfactant compositions, can not produce the large liquid piece that forms big particle.Therefore, by using many fluid tips to adding the foam that shows adhesive anionic surfactant compositions while contacting with powder in container rotary mixing machine, can be with good yield manufacture detergent particles group.
Further, one of feature of the present invention is for being used the foam of multithread body nozzle spray anionic surfactant compositions.
Anionic surfactant compositions, by producing foamed body, not only shows tackiness when contacting with powder, and proportion also reduces.If use the such foam of multithread body nozzle spray, can generate the fine drop that proportion reduces, its number also increases.Its result, with the granulation of detergent use powder raw material in, anionic surfactant compositions shared volume in each detergent particles increases, and because this anionic surfactant compositions becomes foam, proportion reduces, therefore, with the situation of this anionic surfactant compositions producing foamed body is not compared, because the density of every 1 detergent particles reduces, therefore, the detergent particles group of low volume density in accessing.
Like this, in the present invention, by combination, adopt container rotary mixing machine and many fluid tips, further use the foam of anionic surfactant compositions, thereby can play in the situation that using separately respectively the detergent particles group's of low volume density effect in unforeseeable can obtaining with good yield.
Embodiment as the granulation in manufacture method of the present invention, so long as use container rotary mixing machine agitator treating agent powder raw material, and use many fluid tips by the foam of anionic surfactant compositions be sprayed to embodiment in this detergent use powder raw material just without particular limitation of.Below, the embodiment for an example as manufacture method of the present invention illustrates in greater detail.
