Embodiment 1

[0165] Example 1 (Preparation of Detergent Granules)

[0166] 100 parts by mass of 60°C sodium alkylsulfate and 135 parts by mass of 60°C sodium dodecylbenzenesulfonate were mixed to prepare an anionic surfactant composition. The prepared anionic surfactant composition was a surfactant paste containing 52.8 parts by mass of water relative to 100 parts by mass of the anionic surfactant. In addition, the viscosity of this paste at 60° C. was 1.7 Pa·s.

[0167] 1.81 kg of light ash and 3.42 kg of pulverized sodium sulfate were added to a drum mixer as detergent powder materials, and stirred for 30 seconds at a Froude number of 0.2. Stirring was continued afterwards, and 1.55 kg of the foam of the anionic surfactant composition modulated by the above-mentioned MDFO was added in 17 minutes, and the micronization gas was 80 L / min (the volume flow rate of the foam / the flow rate of the micronization gas) 5.3cm 3 / L) under the spray condition of two-fluid nozzle to add, stir for 1 m...

Embodiment 2

[0170] Sodium alkyl sulfate was adjusted to 60°C as an anionic surfactant composition. The prepared anionic surfactant composition was a surfactant paste containing 51.52 parts by mass of water with respect to 100 parts by mass of the anionic surfactant. In addition, the viscosity of this paste at 60° C. was 1.4 Pa·s.

[0171] 4.20 kg of pulverized sodium sulfate was added to a drum mixer as a detergent powder raw material, and stirred for 30 seconds at a Froude number of 0.2. Afterwards, continue to stir, and the foam of the anionic surfactant composition of 2.80kg modulation is 33 minutes in addition time, and the micronization gas is 80L / min (the volume flow rate of foam / micronization gas flow is 5.3cm 3 / L) under spray conditions, add with a two-fluid nozzle, and stir for 1 minute after adding. That is, 66.7 mass parts of this foam was sprayed at 60 degreeC with respect to 100 mass parts of powder raw materials for detergents. Thereafter, stirring was stopped, and the ...

Embodiment 3

[0174] Except that the flow rate of gas for micronization is 42 L / min (volume flow rate of foam / flow rate of gas for micronization is 10.0 cm 3 / L), granulation was performed under the same conditions as in Example 2. The specific gravity of the foam of the anionic surfactant composition sprayed through the two-fluid nozzle was 0.68. Table 1 shows the composition and physical properties of the obtained detergent particle group.

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 [0001] This invention relates to the manufacturing method of the detergent particle group which used the container rotation type mixer, the foam of an anionic surfactant composition, and a multi-fluid nozzle. Background technique [0002] Among the currently commercially available detergents, there are roughly classified high-volume-density detergents (greater than 690g / L), medium-volume-density detergents (400-690g / L), low-volume-density detergents (above 250g / L and less than 400g / L), liquid detergent, etc. For example, high-volume-density detergents are often used in Japan, but in Asia, Oceania, or Europe, there is also a large demand for medium- and low-volume-density detergents. [0003] From the viewpoint of economical efficiency and environmental response, as a manufacturing method not using spray drying, a manufacturing method of a detergent composition using an anionic surfactant by a non-spray drying method is disclosed. Patent Document 1 discloses...
