In this state, the processing products A and B stored in the hoppers 24 and 25 are supplied to the inside of the outer tank 1 from the supply nozzles 20 and 21 by the metering pumps 22 and 23.

Then, the processed products A and B supplied from the two supply nozzles 20 and 21 to the inside of the outer tank 1 by the metering pumps 22 and 23 reach the inside of the inner tank 2, and further the guide blades 11 of the inner tank 2. To the axial blade 12.

The processed materials A and B supplied to the inside of the disperser by the axial flow blade 12 become a large amount of circulating flow, and the processed materials A and B are further circulated by the rotor 15 and the stator 1.
6, a strong shearing force and a repetitive pressure fluctuation are applied to the treatments A and B during this passage, so that the treatments A and B
B is strongly dispersed and emulsified.

The circulating flow inside the dispersing machine is several tens to several hundreds times as large as the supply pumps 22 and 23, and the processed products A and B are tens to several tens while being retained inside the dispersing machine. Since it is subjected to the dispersing action 100 times, it is possible to obtain a very uniform and high-quality dispersion and emulsion together with the dispersing action with the dispersing member 14 thereafter.

The dispersed and emulsified products can be taken out through the discharge holes 10 provided in the dispersion plate 8 and further through the product discharge nozzle 28 to the outside.

Since the outer tank 1 and the inner tank 2 are both formed of double walls, cooling water is supplied to cooling water supply nozzles 26 and 27 connected to the respective tanks 1 and 2 so that the cooling water is supplied. If the water is discharged from the water discharge nozzles 29 and 30, the heat generated during dispersion and emulsification can be cooled, and the efficiency of dispersion and emulsification can be increased.

The case where the treated materials A and B in 4, 25 are continuously supplied to obtain the dispersion and the emulsion continuously is described. However, the present invention is not limited to this, and the treated materials A and B in the hoppers 24 and 25 are not limited thereto.
Alternatively, B may be supplied in a batch, and a batch process may be performed to obtain a dispersion and an emulsion in a batch.

[0027]

According to the present invention, as described above, the processed material supplied from the supply nozzle by the rotation of the axial flow blade becomes a large circulating flow, and further, a strong shear force generated between the rotor and the stator. And the repeated pressure fluctuations cause the processed product to be strongly dispersed and emulsified.

Further, since the inner and outer tanks are formed of double walls, by supplying cooling water between the two walls, the heat generated during dispersion and emulsification can be suppressed, and the efficiency of dispersion and emulsification can be increased. Things.
