In this rotor 1, the disk 11 is divided into a central portion where the inner blade group 13 is attached and an outer peripheral portion where the outer blade group 12 is attached (see a circle from the center indicated by a virtual line in the figure). It may be manufactured as a two-piece type, or may be a one-piece type manufactured without division.

The outer blade group 12 is composed of a plurality of plate-like blades 15 having a substantially triangular cross-section.
The disk 11 is disposed on the outer periphery of the disk 11 so as to be located on the same circumference with a predetermined distance therebetween, and is inclined in the rotation direction (arrow Y in the drawing) from the tangent X of the disk 11 toward the center. Attached. Here, the size and the number of the plate-like blades 15 are not particularly limited. For example, among the conventional high-speed stirrers, the outer blade group of the rotor of the same type as the high-speed stirrer of the present invention is used. It can be the same as the plate-shaped blade to be configured.

On the other hand, the inner blade group 13 is inclined in a helical arc in the rotational direction (arrow Y in the drawing) toward the center direction.
It consists of four attached curved blades 16, and each curved blade 16 is formed such that its cross-sectional shape is tapered at the center. These curved blades 16 have the same interval near the center of the disk 11 so as to have a gap between the mounting position of the outer blade group 12 and the fixing pin 17 (see FIG. 2) of the stator 2. It is arranged in. In addition, the number of the curved blades 16 is not particularly limited, and can be appropriately selected depending on the size of the disk and the like. Usually, about 3 to 8 sheets are suitable.

The stator 2 shown in FIG. 2 is provided with an opening 18 at the center, and is directed toward the opening 18 on the upper surface side (the rear surface side in FIG. 2) so that fluid can easily flow through the opening 18. It has an inclined surface 19 (see FIG. 4), and is located on the lower surface of a disk 21 provided with four screw holes 20 for fixing to the gantry 3 (see FIG. 3).

And the centrifugal force generated by the high-speed rotation of the rotor 1 causes the fluid flowing into the high-shear mixing section to flow between the plate-like blades 15 of the outer blade group 12 and the gantry 3. And can be extruded from the high shear mixing section.

Next, an example of the structure of the stirring apparatus of the present invention will be described with reference to FIG. 5. In the stirring apparatus B shown in FIG. 5, a recess 27 for accommodating a high-speed stirrer is provided at the bottom of the tank body 26. A stirring tank 28 and a pipe 29 connecting the upper part of the tank main body 26 and the concave portion 27 are provided.
The motor 30 is connected to the motor 30 via a (bearing portion 31), and these are lifted and lowered by a lifter 32 (hydraulic cylinder) so that the high-speed stirrer A can move between the tank main body 26 and the concave portion 27. is there.

In the stirring device B, when the high-speed stirrer A is located in the tank main body 26 of the stirring tank 28, the discharge flow of the high-speed stirrer A forms a circulating flow in the stirring tank 28. on the other hand,
When the high-speed stirrer A is located in the concave portion 27 of the stirring tank 28,
As shown by an arrow in FIG. 5, the discharge flow of the high-speed stirrer A is connected to a pipe 29 returning to the upper part of the stirring tank 28, and forms an external circulation flow. This external circulation flow has the effect of increasing the vertical mixing in the stirring tank 28, and is particularly effective at the time of defoaming under reduced pressure.

Therefore, as the stirring tank of the stirring device B,
If a vacuum stirrer is used, the required raw materials are charged into the stirrer in an appropriate order, and mixed, sheared, and defoamed under reduced pressure, so that various compositions with excellent quality such as uniformity can be obtained in a short time. Product, and such a production method is particularly useful as a method for producing a high-viscosity material of the present invention. As the high-viscosity material, more specifically, for example, a high-viscosity emulsion, suspension, or the like is used. Various compositions can be mentioned, and among them, for example, it is particularly effective as a method for producing toothpaste or the like.

In the case of producing a high-viscosity material according to the present invention, as the raw material components, usually-blended components can be blended in a usual dose. For example, in the case of toothpaste, wetting agents, abrasives, fragrances and the like are used. , A binder, a foaming agent, water and the like can be mentioned as raw material components.

As the low-speed stirring blade of the vacuum stirring device, for example, a planetary agitator or an anchor-type agitator that rotates and revolves, a turbine, or the like can be used.

When the high-speed stirrer is operated, the shearing conditions can be appropriately selected.
0 to 3,000 rpm, especially 1,000 to 1,500 r
pm is preferable.

During the operation of the high-speed stirrer, it is preferable that the low-speed rotation type stirring blade is also operated at, for example, about 10 to 50 rpm to stir the whole inside of the tank.

In the case of the above-mentioned production method, the

Things. In this case, the degree of vacuum is appropriately selected,
1.33 × 10^FourPa (100 Torr) or less, especially
1.33 × 10^Three~ 6.65 × 10 ^ThreePa (10 to 50T
degassing under reduced pressure of about (or)
It is preferable from the viewpoint of defoaming.

In the above-mentioned production method, a suitable number of passes for the high-speed stirrer is set as the number of passes defined by the following equation in accordance with the composition and type of the high-viscosity material to be prepared in advance. This setting pass number is, for example, if the high-viscosity material is toothpaste,
Usually, it is preferably 1 to 10 times, particularly preferably 1 to 6 times.

That is, the relationship between the number of passes and the properties of the obtained high-viscosity material is such that, for example, when a toothpaste is produced as a high-viscosity material, the more the number of passes, the better the texture of the paste (micro-dispersion of the abrasive). The shape retention tends to be worse (the viscosity decreases due to cutting of the binder) as the number of passes increases. Therefore, by performing the above-mentioned number of passes, it is possible to satisfy all the properties of the obtained high-viscosity material, and if the number of passes is not one or more than ten, with uniform dough, In some cases, toothpastes (high-viscosity products) having good shape retention cannot be produced.

When a high-viscosity material is manufactured by the above-described manufacturing method by setting the number of passes in this way, for example, a flow meter is interposed in the above-mentioned pipe so that the flow rate of the pipe due to external circulation by the high-speed stirrer can be measured. It is set so that the high-speed stirrer is automatically stopped when the integrated capacity of the pipe flow rate after starting the external circulation reaches the product of the content capacity and the set number of passes. Is more preferable.

Here, as the flow meter, for example, a capacity type flow meter, a mass flow meter, an electromagnetic flow meter, etc. can be used.
An electromagnetic flowmeter is preferable for measuring a highly viscous fluid with high accuracy.

In the present invention, the number of passes is defined by the following equation. Number of passes = (Integrated volume that passed through the flow meter since the start of external circulation) / (Content volume)

Here, in the above equation, the accumulated volume that has passed through the flow meter after the start of external circulation is calculated using the instantaneous volume flow rate measured by the flow meter after the external circulation by the high-speed stirrer is started. The integrated capacity after the start of circulation can be obtained by online calculation. In addition, the content volume, if the high-viscosity material is, for example, toothpaste, wetting agents, abrasives, fragrances, binders, foaming agents, the specific gravity of the mixture and the specific gravity of the mixture of the raw material components of the toothpaste, such as water. Can be calculated from
