Summary of the invention
The present invention relates to the manufacture method of a kind of detergent particles group, the manufacture method of described detergent particles group has use container rotating type mixing machine by the operation of detergent use powder raw material granulation, and the manufacture method of described detergent particles group is that the foam multi fluid nozzle of anionic surfactant compositions is sparged the granulation carrying out this detergent use powder raw material in this container rotating type mixing machine.
Embodiment
The present invention relates to and provide with not using spray-dired method to contain the method for the detergent particles group of low volume density in anion surfactant with good yield manufacture.
By the manufacture method of detergent particles group of the present invention, the effect of the detergent particles group of low volume density in can obtaining with good yield can be produced.In obtaining like this, the detergent particles group of low volume density also has the high deliquescent effect of display.
One of the present invention is characterised in that, uses container rotating type mixing machine to carry out the granulation of detergent use powder raw material.
In general, when using container rotating type mixing machine to carry out granulation, powder can be made to flow equably, in addition, owing to taking up and causing due to deadweight with what cause particle due to rotation the mixed organization that landing falls, thus inhibit the shearing force put on powder.Therefore, can say that the prilling process of the mixing machine described in use is the prilling process of non-densification.In addition, if just can not granulation be carried out by force due to the tackiness of anionic surfactant compositions when contacting with powder of adding in described mixing machine, therefore, need to show tackiness when contacting with powder.If the single fluid nozzle or the pipe arrangement that such anionic surfactant compositions are used as common supply method are supplied to container rotating type mixing machine, can find to be difficult in mixing machine, make the liquid component of supply disperse equably, easily form the tendency of thick particle due to the large liquid block of local generation.
At this, use the multi fluid nozzle of two-fluid spray nozzle etc., by spraying, the foam showing adhesive anionic surfactant compositions when contacting with powder is supplied in container rotating type mixing machine, is surprised to find that the formation that can suppress big particle also can granulation equably.This is considered to due to the drop by using multi fluid nozzle to make the foam of such anionic surfactant compositions become fine in advance, even if thus in container rotating type mixing machine, also can reach the high dispersive of the foam of anionic surfactant compositions, can not produce and form the large liquid block of big particle.Therefore, show the foam of adhesive anionic surfactant compositions when adding by using multi fluid nozzle and contact with powder in container rotating type mixing machine, detergent particles group can be manufactured with good yield.
Further, one of feature of the present invention is the foam using multi fluid nozzle spraying anionic surfactant compositions.
Anionic surfactant compositions is by producing foamed body, and not only show tackiness when contacting with powder, proportion also reduces.Such foam if use multi fluid nozzle is sprayed, can generate the fine drop that proportion reduces, its number also increases.Its result, with the granulation of detergent use powder raw material, the volume increase that anionic surfactant compositions is shared in each detergent particles, and becoming foam due to this anionic surfactant compositions, proportion reduces, therefore, with not by compared with the situation of this anionic surfactant compositions producing foamed body, because the density of every 1 detergent particles reduces, therefore, it is possible to the detergent particles group of low volume density in obtaining.
Like this, in the present invention, container rotating type mixing machine and multi fluid nozzle is adopted by combination, the foam of further use anionic surfactant compositions, thus can play when individually using unforeseeable can obtain with good yield in the effect of detergent particles group of low volume density.
As the embodiment of the granulation in manufacture method of the present invention, as long as use container rotating type mixing machine agitator treating agent powder raw material, and use multi fluid nozzle the foam of anionic surfactant compositions is 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.

The volume density of the detergent particles group obtained in embodiment 1 ~ 9 is 444 ~ 682g/L.In addition, granulation yield is more than 96%, can yield obtain well in the detergent particles group of low volume density.Further, even if the many composition of the sodium sulfate falling into heavy kind in detergent use powder raw material also can obtain the detergent particles group of low volume density by yield well.
On the other hand, for comparative example 1,2 and 4, become the detergent particles group than embodiment high volume density (more than 715g/L).This is considered to the foam owing to not using anionic surfactant compositions, can not give the effect of the foam being made up of particle low-gravity anionic surfactant compositions.
For comparative example 3, reduce (60.6%) than embodiment granulation yield.Although this thinks the foam owing to employing anionic surfactant compositions; but micronize gas is 0L/min; namely actually by single fluid nozzle spraying foam; the high dispersive of foam can not be reached thus, the tackiness had due to foam and the formation of big particle occurs.Further, for comparative example 3, become the detergent particles group than embodiment high volume density (743g/L).This is considered to supply because the foam of anionic surfactant compositions becomes large liquid block, its result is with the contact of detergent use powder raw material, the hydration of detergent use powder raw material or time increase compared with the situation of fine droplets of dissolving institute's time spent and being cooled by detergent use powder raw material, foam is difficult to solidification, more easily causes the lather collapse of foam in granulation.
Further, if compare the identical embodiment 1 of composition and comparative example 1, then 60 seconds dissolution rates improve, and granular sensation extinction time also shortens.This also can judge volume density step-down compared with comparative example 1 from embodiment 1, be considered to owing to passing through to use foam, thus intragranular space is increased, and easily dissolves.Further, as shown in the value of coarse grain rate and micro mist rate, size distribution becomes sharp-pointed, and mobility also improves.
The possibility that industry utilizes
By the present invention, the detergent particles group of low volume density in manufacturing with good yield with not using spray-dired method.Such detergent particles group as the detergent composition of the various uses such as dress material use, or preferably can use as a kind of composition of such detergent composition.
