An object of the present invention is to provide a swirl-type melting method and a swirl-type melting apparatus capable of performing high-precision melting even for highly viscous materials to be dissolved.

The swirl-type dissolution method of the present invention includes a fluid-like material introducing step of introducing a fluid-like material from the introducing portion into a cylindrical container having an introducing portion and a discharging portion, and the fluid state introduced in the fluid-like material introducing step. A swirl generating step for swirling an object inside the cylindrical container, a dissolved substance supplying step for supplying a fine substance-like dissolved substance to the cylindrical container, and the dissolution target in the vicinity of the inner wall of the cylindrical container To-be-dissolved substance supply control step for allowing or preventing the supply of an object to the inside of the cylindrical container, and swirl flow for causing the fluid-like substance and the object to be dissolved to flow downstream while swirling inside the cylindrical container And a swirl discharge step of discharging from the discharge section while swirling the dissolved material in which at least a part of the fluid and the material to be dissolved is swirled, The axial center of the cylindrical container and the material to be dissolved The supplied in sheet process, characterized in that respectively coincide with the supply axis of the lysate.

The swirl-type dissolving apparatus of the present invention is a swirl-type dissolving apparatus for producing a melt by dissolving at least a part while swirling a fluid-like substance and a fine substance-like substance to be melted. A cylindrical container having an introduction part to be discharged and a discharge part from which the dissolved substance is discharged to the outside, a fluid-like substance introduction part for introducing the fluid substance from the introduction part into the cylindrical container, and A swirl generator that swirls the fluid-like material introduced from the introduction portion inside the cylindrical container, and a material to be dissolved that is disposed in the vicinity of the inner wall of the cylindrical container and supplies the material to be dissolved to the cylindrical container A supply unit, and a dissolved material supply control unit that allows or prevents supply of the material to be dissolved into the cylindrical container, and the fluid and the material to be dissolved are inside the cylindrical container. The swirling axis inside the cylindrical container The axis of the serial tubular container, characterized by matching each of the said in the feed axis of the lysate supplied in the melt feeding step.
In the present invention, fine substances having high viscosity such as carboxymethyl cellulose (CMC), pectin, and wheat flour can be exemplified as the substance to be dissolved, and water for dissolving the substance to be dissolved can be exemplified as the fluid substance.

In the present invention, the fluid-like material introducing step is performed by the fluid-like material introducing portion, and the swirl generating step is performed by the swirl generating portion. When the fluid-like material is continuously introduced from the introduction portion into the cylindrical container by the fluid-like material introducing step, and when the fluid-like material is swirled inside the cylindrical container by the swirl generation step, A swirl flow process is performed inside, and the fluid-like material flows toward the discharge portion on the downstream side while swirling inside the cylindrical container.
In a state where the fluid substance spirally flows along the inner surface of the cylindrical container, the dissolved substance supply control unit performs the dissolved substance supply control process, and introduces the dissolved substance into the cylindrical container. Is acceptable. Then, a swirl flow process will be implemented and a fluid-like substance and a to-be-dissolved substance will flow toward the discharge part in the downstream, swirling inside a cylindrical container.
Here, when the specific gravity of the material to be dissolved is smaller than that of the fluid material, a large centrifugal force acts on the fluid material having a large specific gravity, and the material to be dissolved having a specific gravity smaller than that of the fluid material follows the inner surface of the cylindrical container. It becomes easy to flow to the discharge part side. Immediately after being introduced into the cylindrical container from the introduction part, the material to be dissolved is confined in the axial core of the cylindrical container by the large centrifugal force of the fluid, so there is no mixing with the fluid, As it approaches the discharge side, the fluid is turbulent, and the material to be dissolved and the fluid are mixed and dissolution occurs.
Then, the swirling discharge process is performed, and the dissolved material in which at least a part of the fluid-like material and the material to be dissolved is dissolved is discharged from the discharging portion while swirling the inside of the cylindrical container. Here, the lysate discharged from the discharge part includes a completely lysed product completely dissolved and a semi-lysed product partially dissolved. If the material to be dissolved is easy to dissolve and the tube container is long enough to carry out the swirl flow process, it can be completely dissolved.

When a predetermined amount of the material to be dissolved is sent into the cylindrical container, the material supply control unit prevents the material to be dissolved from being supplied into the cylindrical container. Even if the supply of the material to be melted to the inside of the cylindrical container is prevented, the fluid-like substance flows toward the discharge portion on the downstream side while swirling inside the cylindrical container.
In general, control of introduction of a material to be dissolved into a cylindrical container is often performed by a valve, but contact between the material to be dissolved and a fluid material occurs on the downstream side of this valve, and the inner wall of the cylindrical container Adhesion of the material to be dissolved becomes a problem. However, in the present invention, the melted material supply control unit is installed in the vicinity of the inner wall of the cylindrical container, and when the melted material supply control unit prevents the melted material from being supplied to the inside of the cylindrical container. Since the fluid matter swirls inside the cylindrical container, the swirling flow of the fluid matter comes into contact with the downstream side of the melt supply control unit and has an effect of removing the adherent melt material. That is, due to the swirling flow of the fluid-like material, a cleaning effect is exerted on the downstream side of the dissolved material supply control unit, and adhesion of the dissolved material to the dissolved material supply control unit is prevented.
In the present invention, the melt supply control unit can intermittently introduce the melt into the cylindrical container, and the flow rate of the melt during the melting operation can be easily adjusted.

Furthermore, in the present invention, since the pivot axis inside the cylindrical container coincides with the axial center of the cylindrical container and the supply axis of the dissolved material supplied by the dissolved material supply unit, Due to the centrifugal force generated by the swirling flow, a coating layer made of a fluid substance is formed on the inner wall of the cylindrical container, and the material to be dissolved can be prevented from coming into direct contact with the inner surface of the cylindrical container. . In general, when the non-dissolved material is a fine material such as a powder or a small solid material, since it contains a large amount of air, the bulk density is small, so that it can be used favorably for dissolving most of the fine materials.
From the above, even a highly viscous material to be dissolved can be dissolved with high accuracy without clogging the material to be dissolved.

In the swirl type melting method of the present invention, the melt supply control step controls the supply amount of the melt to be supplied to the cylindrical container by the melt supply valve, and the swirl flow step includes the melt dissolution step. It is good also as a structure where the downstream side of the said to-be-dissolved material supply valve contacts the swirling flow of the said fluid-like material or the said melted material when a material supply valve is closed.
In the swirl type melting device of the present invention, the melt supply control unit may include a melt supply valve that controls a supply amount of the melt to be introduced into the cylindrical container.
In the above configuration, since the supply amount of the melted material into the cylindrical container can be accurately controlled by the melted material supply valve, a necessary amount of the melted material is introduced into the cylindrical container. By doing so, dissolution of the material to be dissolved can be performed with high accuracy.
In addition, since the melt supply valve is installed near the inner surface of the cylindrical container, when the melt supply valve is closed, the swirl flow of the fluid contacts the downstream side of the valve and adheres to it. The dissolved object is removed, and adhesion of the dissolved object is prevented.

In the swirl-type melting method of the present invention, the fluid-like material introducing step and the swirl generating step include the fluid-like material from the tangential direction of the inner periphery of the cylindrical container in a plane orthogonal to the swivel axis. It is good also as a structure implemented by injecting inside a cylindrical container.
In the swirl-type dissolving device of the present invention, the fluid-like material introducing portion and the swirl generating portion are arranged such that the fluid-like material is introduced from the tangential direction of the inner periphery of the cylindrical container in a plane orthogonal to the swivel axis. It is good also as a structure provided with the injection part injected to the inside of a cylindrical container.
In these configurations, a so-called cyclone system is adopted, and the fluid to be dissolved can be reliably swirled to dissolve the material to be dissolved with high accuracy. In addition, since the fluid-like material introduction part and the swirl generation part are constituted by the injection part, the number of parts can be reduced and the manufacturing cost can be reduced.

In the swirl type melting method of the present invention, the melt supply step may be configured to depressurize the inside of the cylindrical container.
In the swirl type melting device of the present invention, the melt supply unit may include a decompression unit that decompresses the inside of the cylindrical container.
In these configurations, by reducing the pressure inside the cylindrical container, the material to be dissolved is smoothly introduced into the cylindrical container. Therefore, the material to be dissolved is reliably dissolved and the dissolution accuracy is improved.

In the swirl type melting method of the present invention, the melt supply step may be configured to pressurize the melt and press-fit into the cylindrical container.
In the swirl type melting device of the present invention, the melted material supply unit may include a press-fitting unit that pressurizes the melted material and press-fits the melted material into the cylindrical container.
In this configuration, the press-fitting portion is operated to pressurize the material to be dissolved and press-fit into the cylindrical container. Accordingly, since the material to be dissolved is smoothly introduced into the cylindrical container, the material to be dissolved is reliably dissolved and the dissolution accuracy is improved.

In the swirl type dissolution method of the present invention, the swirl discharge step discharges the semi-dissolved material in which the fluid-like material and the material to be dissolved are partially dissolved from the discharge portion to a sealed container, and the semi-dissolved material is sealed. It is good also as a structure provided with the stirring process which stirs inside a container and melt | dissolves completely.
In the swirl type dissolution apparatus of the present invention, a sealed container for storing the fluid-like material discharged from the discharge part and a semi-dissolved material in which the material to be dissolved is partially dissolved, and the semi-dissolved material provided in the sealed container It is good also as a structure provided with the stirring part which stirs inside the said airtight container and melt | dissolves completely.
In these configurations, even if the substance to be dissolved is not sufficiently dissolved inside the cylindrical container and is discharged from the discharge part as a semi-dissolved substance, the semi-dissolved substance is sent from the discharge part to the inside of the sealed container. Since the lysate is stirred by the stirring part, a complete lysate can be obtained.
In the above-described configuration, when the semi-dissolved material is discharged into the sealed container, there are a method of supplying the liquid on the liquid level in the sealed container and a method of supplying the liquid under the liquid surface, and the present invention is not limited thereto. However, the latter has great practical advantages.
In particular, in the case of a highly soluble and poorly soluble material to be dissolved, the material to be dissolved supplied on the liquid surface is liable to infiltrate partly while floating on the liquid surface. When the material to be dissolved is supplied directly below the liquid level in the sealed container, the material to be dissolved is completely dissolved by eliminating the waste by immediately stirring in the stirring unit. Further, this configuration has an advantage that foaming at the liquid level can be prevented.

In the swirl-type dissolution method of the present invention, the discharge port of the discharge part is located below the liquid level of the semi-dissolved material inside the sealed container, and the dissolution object supplying step is performed between the inside and the outside of the sealed container. It is good also as a structure which suck | inhales and introduces the said to-be-dissolved material into the inside of the said cylindrical container by the differential pressure | voltage with this.

It is good also as a structure provided with the pressure reduction pump which attracts | sucks and introduces the said to-be-dissolved substance into the inside of the said cylindrical container by the differential pressure | voltage with this.
In these structures, the to-be-dissolved substance supply process is implemented by operating the vacuum pump. The melted substance supply step generates a differential pressure between the inside and the outside of the sealed container, and this differential pressure creates a negative pressure inside the cylindrical container, and the melted substance is sucked and introduced into the cylindrical container. Therefore, since it is not necessary to provide the cylindrical container with a decompression device for decompressing the inside of the cylindrical container, the structure of the cylindrical container can be simplified.

(Swivel melting method)
Next, the swirl type melting method of the first embodiment will be described.
The fluid-like material introducing unit 3 performs a fluid-like material introducing step to introduce the fluid-like material into the cylindrical container 1 through the introducing unit 12, and the swirl generating unit 4 performs the swirling flow step. Then, the fluid is swirled inside the cylindrical container 1. Then, the fluid-like substance swirls along the inner peripheral surface of the cylindrical container 1 and, depending on the weight of the fluid-like substance and the direction of the fluid-like substance sent by the swirl generator 4, the discharge part 13 is located downstream. Turn towards.

Then, the to-be-dissolved substance supply control part 5 is controlled, supply of the to-be-dissolved substance to the cylindrical container 1 is permitted, and a to-be-dissolved substance supply process is implemented.
Then, the swirl flow process is performed inside the cylindrical container 1, and the fluid and the substance to be dissolved flow downstream while swirling inside the cylindrical container 1. Here, when the material to be dissolved has a specific gravity smaller than that of the fluid material, a large centrifugal force acts on the fluid material having a large specific gravity, and the material to be dissolved having a specific gravity smaller than that of the fluid material is the axis of the cylindrical container 1. It becomes easy to flow to the discharge part 13 side along. Immediately after being introduced into the cylindrical container from the introduction part, the substance to be dissolved is confined in the axial core of the cylindrical container 1 by the large centrifugal force of the fluid, so it is difficult to dissolve with the fluid, As it approaches the discharge unit 13 side, the fluid-like material turbulently flows and the material to be dissolved is easily dissolved.
The material to be dissolved is gradually dissolved in the fluid. In the first embodiment, inside the container main body 11, the object to be dissolved is not completely dissolved in the fluid-like material, and the discharge part is a semi-dissolved material in which a part of the object to be dissolved is dissolved in the fluid-like part. The swivel discharge process carried out from 13 to the sealed container 6 is performed. When the axial length of the container body 11 is increased or a material to be dissolved having a low viscosity is used, the material to be dissolved is completely dissolved in the fluid-like material in the sealed container 6. To the sealed container 6 is completely dissolved.

The semi-dissolved material continues to be sent to the sealed container 6 through the discharge portion 13, and the liquid level of the semi-dissolved material and the complete dissolved material is positioned above the discharge port 13 A of the discharge portion 13.
Then, the decompression pump 23 is operated to carry out the melt supply process. That is, when the pressure difference between the inside and the outside of the sealed container 6 is generated by the decompression pump 23, the material to be dissolved is sucked into the inside of the cylindrical container 1.
And the stirring part 7 is operated and a stirring process is implemented. In the stirring step, the semi-dissolved material stored in the sealed container 6 is stirred to become a complete dissolved material. The complete lysate is sent to the next step by the discharge mechanism 61.
When a predetermined amount of the material to be dissolved is sent into the cylindrical container 1, the material supply control unit 5 prevents the material to be dissolved from being supplied into the cylindrical container.
Even if the supply of the material to be melted to the inside of the cylindrical container 1 is prevented, the fluid-like substance flows toward the discharge portion on the downstream side while turning inside the cylindrical container. Here, since the fluid-like substance is swirling inside the cylindrical container 1, the swirling flow of the fluid-like substance contacts the downstream side of the substance-to-be-dissolved supply control unit 5, and the adhered substance to be dissolved is removed.

(Effect of 1st Embodiment)
(1) A fluid-like material introduction unit 3 performs a fluid-like material introduction step, a swirl generation unit 4 performs a swirl generation step, and a to-be-dissolved material supply control unit 5 performs a to-be-dissolved material supply control step. When supply of the material to be dissolved into the cylindrical container 1 is allowed, a swirl flow process in which the fluid and the material to be dissolved flow toward the discharge unit 13 on the downstream side while swirling inside the cylindrical container 1. As a result, a swivel discharge process is performed in which a semi-dissolved material in which at least a part of the material to be dissolved is dissolved in the fluid is discharged from the discharge unit 13 to the outside of the sealed container 6. In the present embodiment, the swivel axis P1 inside the cylindrical container 1 coincides with the axis P2 of the cylindrical container 1 and the supply axis P3 of the material to be dissolved supplied by the material supply unit 2. A coating layer made of a fluid-like material is formed on the inner wall of the cylindrical container 1 by the centrifugal force generated by the swirling flow of the fluid-like material, and the material to be dissolved comes into direct contact with the inner surface of the cylindrical container 1. Can be prevented. Therefore, even a highly viscous material to be dissolved can be dissolved with high accuracy without clogging the material to be dissolved.

(2) In the melt supply control step, the supply amount of the melt to be supplied to the cylindrical container 1 is controlled by the melt supply valve constituting the melt supply control unit 5. It is possible to accurately control the supply amount of the substance to be dissolved into the interior of the container, and to dissolve the substance to be dissolved with high precision.
In addition, since the melted material supply valve is installed in the vicinity of the inner surface of the top plate 110 of the cylindrical container 1, when the melted material supply valve is closed, the swirling flow of the fluid is downstream in the valve. And the adhered material to be dissolved is removed to prevent the material to be dissolved from adhering.

(3) If the fluid-like material introducing portion 3 and the swirl generating portion 4 are constituted by the injection portion 4A that injects the fluid-like material into the inside of the cylindrical container 1 from the tangential direction of the inner periphery of the cylindrical container 1, the fluid In addition to being able to accurately dissolve the object to be melted by swirling the solid object, the injection unit 4A serves as both the fluid material introducing unit 3 and the swirl generating unit 4, thereby reducing the number of parts and reducing the manufacturing cost. be able to.

(4) Dissolved material in which at least a part is dissolved by the swirling discharge process is discharged from the discharge unit 13 to the sealed container 6 and is stirred and completely dissolved by the stirring unit 7 inside the sealed container 6 by the stirring process. Therefore, even if the melt discharged from the discharge unit 13 is a semi-dissolved product, the melt can be stirred by the stirring unit 7 to obtain a complete melt.

(5) The discharge port 13A of the discharge unit 13 is located below the level of the semi-dissolved material inside the sealed container 6, and the dissolved material supply step is performed between the inside and the outside of the sealed container 6 by the decompression pump 23. Since the object to be dissolved is sucked and introduced into the cylindrical container 1 by the differential pressure, it is not necessary to provide the cylindrical container 1 with a decompression device for decompressing the inside of the cylindrical container 1. The structure can be simplified.

(Swivel melting method)
The swirl type melting method of the second embodiment will be described.
First, the fluid-like material introducing step and the turning step are performed simultaneously. That is, the fluidized material is ejected in the direction orthogonal to the radial direction within the plane orthogonal to the axial center of the introduction port 101 by operating the injection unit 4A. Then, the fluid is swung along the inner surface of the cylindrical container 1 around the axis of the inlet 101 and flows toward the discharge unit 13 due to the weight of the fluid and the like. The fluid-like material flows in a spiral shape (vortex) toward the discharge portion 13 inside the cylindrical container 1 (see arrow Q1).

And from the discharge part 13, the melt | dissolution thing by which the to-be-dissolved substance was completely melt | dissolved in the fluid body is discharged | emitted outside.
When the above steps are completed, the valve main body 51 of the melt supply control unit 5 is closed so that the melt is not supplied into the cylindrical container 1 through the inlet 101. In this state, since the fluid matter swirls inside the cylindrical container 1, the swirl flow of the fluid matter contacts and adheres to the vicinity of the opening of the communication pipe 22 on the downstream side of the valve body 512.
