Description

The present invention relates to a frozen body manufacturing apparatus for producing a granular or droplet-shaped frozen body by spraying or dropping a liquid raw material toward a freezing low-temperature fluid stored in a bottomed tubular freezing fluid tank.

The frozen body produced by such a frozen body manufacturing apparatus is generally freeze-vacuum dried in a vacuum dryer, and fine powder is produced by the freeze-vacuum drying. That is, such a frozen body manufacturing apparatus will manufacture a frozen body for producing fine powder by freeze vacuum drying.

As a conventional example of such a frozen body manufacturing apparatus, a liquid raw material (suspension) is sprayed from a sprayer toward a freezing low-temperature fluid (n-hexane at −30 ° C.) stored in a freezing fluid tank (container). There is one that prepares a frozen body (ice droplet) (see, for example, Patent Document 1).

Although detailed description is omitted in Patent Document 1, when the prepared frozen body (ice droplets) is transferred to a vacuum dryer, the frozen body (ice droplets) precipitated in a low-temperature freezing fluid is used. ) Is transferred to a stainless steel pad. Then, a pad on which a frozen body (ice droplet) is placed is placed inside a vacuum dryer and freeze-vacuum dried to produce fine powder.

Japanese Unexamined Patent Publication No. 2-43443

In Patent Document 1, a frozen body (ice droplets) precipitated in a low-temperature fluid for freezing is transferred to a pad, and the pad on which the frozen body (ice droplets) is placed is loaded into a vacuum dryer. The frozen body (ice droplets) inside will be transferred to the vacuum dryer.
However, in order to take out the frozen body (ice droplets) precipitated in the freezing low-temperature fluid and transfer it to the pad, for example, the frozen body (ice droplets) precipitated in the freezing low-temperature fluid is used. The work of removing the frozen body (ice droplets) precipitated in the freezing low-temperature fluid from the freezing low-temperature fluid, such as scooping it with a net-like body and transferring it to a pad, is a troublesome and complicated work.

Therefore, the frozen body (ice droplets) in the freezing low-temperature fluid is cumbersome and complicated to take out from the freezing low-temperature fluid. The work of transferring the ice cubes to the vacuum dryer is a troublesome and complicated work, and improvement is desired.

The present invention has been made in view of the above circumstances, and an object of the present invention is to facilitate the work of transferring a frozen body in a low-temperature fluid for freezing to a vacuum dryer, and further, freezing. The point is to provide a frozen body manufacturing apparatus capable of producing a good body.

The frozen body manufacturing apparatus of the present invention prepares a granular or drop-shaped frozen body by spraying or dropping a liquid raw material toward a low-temperature freezing fluid stored in a bottomed tubular freezing fluid tank. And its characteristic composition is
A bottomed tubular shape having a bottom wall portion that cannot pass through the frozen body and that can pass through the low-temperature fluid for freezing, and a side wall portion that is non-porous and has a smooth inner surface. The frozen body accommodating body is provided in a state where the bottom wall side portion is immersed in the freezing low-temperature fluid so as to be freely attached to the freezing fluid tank and detachably above the freezing fluid tank.
The bottom wall portion of the frozen body accommodating body is configured to be openable and closable for taking out the frozen body.

That is, since the bottomed tubular frozen body storage body is attached to the freezing fluid tank in a state where the bottom wall side portion is immersed in the freezing low-temperature fluid, the freezing fluid stored in the freezing fluid tank is used for freezing. The frozen body produced by spraying or dropping the liquid raw material toward the low-temperature fluid is stored inside the frozen body storage body.

Since the frozen body storage body can be separated from the upper part of the freezing fluid tank, the frozen body storage body is frozen when the prepared frozen body is taken out from the freezing low temperature fluid of the freezing fluid tank. The prepared frozen body can be easily taken out from the freezing low-temperature fluid simply by separating it above the fluid tank.
When the frozen body is separated from the freezing fluid tank, the freezing low-temperature fluid inside the frozen body is discharged to the outside through the bottom wall of the frozen body. ..

In addition, since the bottom wall of the frozen body storage body is configured to be openable and closable for taking out the frozen body, when the frozen body stored in the frozen body storage body is loaded into the vacuum dryer, By opening the bottom wall of the frozen body storage body, the frozen body stored in the frozen body storage body can be taken out from the bottom wall part of the frozen body storage body and loaded into the vacuum dryer. The frozen body stored in the body storage body can be easily loaded into the vacuum dryer.

By the way, for example, when the frozen body stored in the frozen body storage body is loaded into the vacuum dryer, the frozen body storage body is turned upside down and the frozen body is taken out from the upper opening of the frozen body storage body while vacuuming. It is conceivable to load the frozen body into a dryer, but in this case, the work of turning the frozen body storage body upside down becomes complicated, and the frozen body melts and adheres to the upper portion of the side wall portion of the frozen body storage body. There is a risk of causing trouble.

In this way, the prepared frozen body can be easily taken out from the freezing low-temperature fluid in the freezing fluid tank, and the frozen body stored in the frozen body storage body can be easily loaded into the vacuum dryer. Therefore, it is possible to facilitate the work of transferring the frozen body in the low-temperature fluid for freezing to the vacuum dryer.

Moreover, since the side wall portion of the frozen body storage body is formed in a form having a non-porous and smooth inner surface, the liquid raw material is sprayed or sprayed on the freezing low-temperature fluid stored in the freezing fluid tank. When the frozen body is prepared by dropping, even if the frozen body is scattered toward the inner surface of the portion located above the low-temperature fluid for freezing in the side wall portion, the scattered frozen body is smooth on the side wall portion. Since it is possible to avoid adhering to the inner surface of the side wall portion and thawing, such as sliding down along the inner surface, a frozen body can be satisfactorily prepared.

In short, according to the characteristic configuration of the frozen body manufacturing apparatus of the present invention, it is possible to facilitate the work of transferring the frozen body in the low-temperature fluid for freezing to the vacuum dryer, and moreover, the frozen body can be satisfactorily prepared. it can.

A further characteristic configuration of the frozen body manufacturing apparatus of the present invention is that the frozen body accommodating body has a bag-shaped body formed by weaving a fiber material and the side wall portion is arranged inside the bag-shaped body. It is configured to include a tubular body to be formed, and to form the bottom wall portion at a bottom side portion of the bag-shaped body located below the tubular body.
An opening for taking out the frozen body is formed in the bottom side portion of the bag-shaped body, and a fastener is provided which is detachably attached to the bag-shaped body in a state where the opening for taking out the frozen body is closed. At the point.

That is, the frozen body accommodating body includes a bag-shaped body formed by weaving a fiber material and a tubular body arranged inside the bag-shaped body to form a side wall portion, and the tubular body in the bag-shaped body. Since it is configured to form a bottom wall portion at the bottom side portion located below the above, that is, a frozen body storage body is formed by combining a bag-shaped body and a tubular body that can be formed separately. Therefore, it is possible to facilitate the production of the frozen body storage body.

Since the bag-shaped body is formed by woven the fibrous material so as to be porous, the size of the hole through which the low-temperature freezing fluid formed in the bag-shaped body passes is determined. Since it can be made small enough, a frozen body of sufficiently small size can be prepared.

Further, since the tubular body formed as a separate body from the bag-shaped body can be formed in a state where the surface is sufficiently smooth with a metal material such as stainless steel, it is stored in the freezing fluid tank. When a liquid raw material is sprayed or dropped toward a low-temperature fluid for freezing to prepare a frozen body, even if the frozen body scatters toward the inner surface of a cylinder that functions as a side wall of the frozen body storage body, the frozen body scatters. It becomes easy to appropriately prevent the frozen body from adhering to the inner surface and thawing.

In addition, an opening for taking out the frozen body is formed in the bottom side portion of the bag-shaped body, and a fastener is provided which is detachably attached to the bag-shaped body in a state where the opening for taking out the frozen body is closed. Therefore, when the frozen body stored in the bag-shaped body is taken out for loading into the vacuum dryer, it is stored in the bag-shaped body by removing the fastener and opening the freezing body taking-out opening. Since the frozen body can be discharged through the freezing body taking-out opening, the frozen body stored in the bag-shaped body can be taken out satisfactorily.

In short, according to the further characteristic configuration of the frozen body manufacturing apparatus of the present invention, it is possible to facilitate the production of the frozen body storage body, and it is possible to prepare a frozen body having a sufficiently small size. Moreover, it is possible to appropriately prevent the frozen body from adhering to the inner surface of the side wall portion and thawing, and further, it is possible to satisfactorily take out the frozen body stored in the frozen body storage body.

A further characteristic configuration of the frozen body manufacturing apparatus of the present invention is that the lower end of the tubular body is positioned so as to press the bottom side portion of the bag-shaped body so as not to be lifted.

That is, the bottom side portion of the bag-shaped body may be lifted when immersed in the low-temperature fluid for freezing, but the lower end of the cylinder presses the bottom side portion of the bag-shaped body so as not to lift the bag. Since the lifting of the bottom side portion of the shape is prevented, the bottom side portion of the bag shape can be maintained in an appropriate state by being immersed in the low temperature fluid for freezing.

In this way, since the bottom side portion of the bag-shaped body can be appropriately maintained in a state of being immersed in the freezing low-temperature fluid, the bottom side portion of the bag-shaped body immersed in the freezing low-temperature fluid is used. It is possible to better produce the frozen body while appropriately storing the frozen body.

In short, according to the further characteristic configuration of the frozen body manufacturing apparatus of the present invention, the frozen body can be produced more satisfactorily.

A further characteristic configuration of the frozen body manufacturing apparatus of the present invention is that the bottom side portion of the bag-shaped body is formed in an inclined shape that becomes thinner toward the opening for taking out the frozen body.

That is, since the bottom side portion of the bag-shaped body is formed in a tapered shape that becomes thinner as it approaches the frozen body taking-out opening, the frozen body stored in the bag-shaped body is discharged through the frozen body taking-out opening. At that time, the frozen body stored in the bag-shaped body is stored in the bag-shaped body because it can be discharged through the frozen body taking-out opening while being gathered at the forming portion of the frozen body taking-out opening. The frozen body can be taken out more satisfactorily.

In short, according to the further characteristic configuration of the frozen body manufacturing apparatus of the present invention, the frozen body stored in the bag-shaped body can be taken out more satisfactorily.

A further characteristic configuration of the frozen body manufacturing apparatus of the present invention is that the frozen body storage body includes a bottomed tubular protective body that detachably stores the bag-shaped body and is formed porously. It is in.

That is, the bag-shaped body formed by woven the fiber material penetrates into the weight of the created frozen body and the inside of the bag-shaped body when it is separated (taken out) upward from the freezing fluid tank. The weight of the low-temperature fluid for freezing may cause damage such as tearing, but by storing the bag-shaped body inside the porously formed bottomed tubular protective body, the bag-shaped body is outwardly formed. Damage to the bag-like body can be suppressed by receiving it with a protective body so as to prevent it from spreading.

Therefore, if the protective body is configured to have sufficient strength with a metal material such as stainless steel, the frozen body can suppress damage to the bag-shaped body without having to provide a large strength to the bag-shaped body. Can be created well.

In short, according to the further characteristic configuration of the frozen body manufacturing apparatus of the present invention, it is possible to satisfactorily prepare the frozen body while suppressing damage to the bag-shaped body.

A further characteristic configuration of the frozen body manufacturing apparatus of the present invention is that a transport trolley on which the freezing fluid tank is mounted so as to be able to move up and down is provided.
The lid of the freezing fluid tank is fixedly arranged so as to be mounted on the freezing fluid tank as the freezing fluid tank is raised from a position below the lid.
A raw material supply unit for spraying or dropping the liquid raw material is attached to the lid.

That is, when creating the frozen body, the freezing fluid tank mounted on the transport trolley is moved to the lower part of the fixedly arranged lid while the transport trolley is running, and then the freezing fluid tank is moved. Is lifted by the lifting operation by the transport trolley so that the lid is attached to the upper part of the freezing fluid tank.

In this way, with the lid mounted on the upper part of the freezing fluid tank, the liquid raw material is sprayed or dropped from the raw material supply unit mounted on the lid to prepare a frozen body.

When the prepared frozen body is transferred to the vacuum dryer, the freezing fluid tank is lowered by a lowering operation by a transport trolley so that the lid is removed from the upper part of the freezing fluid tank.
Next, the freezing fluid tank mounted on the transport trolley is moved to a place where the frozen body is loaded into the vacuum dryer while the transport trolley is running, and then the frozen body storage body is moved above the freezing fluid tank. The frozen body stored in the frozen body storage body is taken out from the bottom wall of the frozen body storage body and loaded into the vacuum dryer.

In this way, since the freezing fluid tank can be moved while being placed on the carrier to the place where the frozen body is to be prepared and the place where the frozen body is loaded into the vacuum dryer, the frozen body is prepared and prepared. The work of transferring the frozen body to the vacuum dryer can be facilitated.

Moreover, when the created frozen body is transferred to the vacuum dryer, the frozen body storage body for storing the frozen body is attached to the freezing fluid tank until just before the frozen body is loaded into the vacuum dryer. In other words, since the frozen body containing the frozen body can be maintained in a state of being immersed in the low temperature fluid for freezing, the frozen body is thawed when the prepared frozen body is transferred to the vacuum dryer. It is possible to satisfactorily transfer the prepared frozen body to a vacuum dryer while avoiding the occurrence of troubles such as damage.

In short, according to the further characteristic configuration of the frozen body manufacturing apparatus of the present invention, it is possible to facilitate the work of preparing the frozen body and transferring the prepared frozen body to the vacuum dryer, and moreover, it is produced. The frozen product can be satisfactorily transferred to a vacuum dryer.

An opening for taking out the frozen body is formed in the bottom side portion of the bag-shaped body, and a fastener is provided which is detachably attached to the bag-shaped body in a state where the opening for taking out the frozen body is closed. At the point.

Further , the frozen body accommodating body includes a bag-shaped body formed by weaving a fiber material and a tubular body arranged inside the bag-shaped body to form a side wall portion, and the tubular body in the bag-shaped body. Since it is configured to form a bottom wall portion at the bottom side portion located below the above, that is, a frozen body storage body is formed by combining a bag-shaped body and a tubular body that can be formed separately. Therefore, it is possible to facilitate the production of the frozen body storage body.

The frozen body manufacturing apparatus of the present invention prepares a granular or drop-shaped frozen body by spraying or dropping a liquid raw material toward a low-temperature freezing fluid stored in a bottomed tubular freezing fluid tank. And its characteristic composition is
A bottomed tubular shape having a bottom wall portion that cannot pass through the frozen body and that can pass through the low-temperature fluid for freezing, and a side wall portion that is non-porous and has a smooth inner surface. The frozen body accommodating body is provided in a state where the bottom wall side portion is immersed in the freezing low-temperature fluid so as to be freely attached to the freezing fluid tank and detachably above the freezing fluid tank.
The bottom wall portion of the frozen body storage body is configured to be openable and closable for taking out the frozen body.
A transport trolley on which the freezing fluid tank can be freely lifted and lowered is provided.
The lid of the freezing fluid tank is fixedly arranged so as to be mounted on the freezing fluid tank as the freezing fluid tank is raised from a position below the lid.
A raw material supply unit for spraying or dropping the liquid raw material is attached to the lid.

That is, since the bottomed tubular frozen body storage body is attached to the freezing fluid tank in a state where the bottom wall side portion is immersed in the freezing low-temperature fluid, the freezing fluid stored in the freezing fluid tank is used for freezing. The frozen body produced by spraying or dropping the liquid raw material toward the low-temperature fluid is stored inside the frozen body storage body.
Since the frozen body storage body can be separated from the upper part of the freezing fluid tank, the frozen body storage body is frozen when the prepared frozen body is taken out from the freezing low temperature fluid of the freezing fluid tank. The prepared frozen body can be easily taken out from the freezing low-temperature fluid simply by separating it above the fluid tank.
When the frozen body is separated from the freezing fluid tank, the freezing low-temperature fluid inside the frozen body is discharged to the outside through the bottom wall of the frozen body. ..
In addition, since the bottom wall of the frozen body storage body is configured to be openable and closable for taking out the frozen body, when the frozen body stored in the frozen body storage body is loaded into the vacuum dryer, By opening the bottom wall of the frozen body storage body, the frozen body stored in the frozen body storage body can be taken out from the bottom wall part of the frozen body storage body and loaded into the vacuum dryer. The frozen body stored in the body storage body can be easily loaded into the vacuum dryer.
By the way, for example, when the frozen body stored in the frozen body storage body is loaded into the vacuum dryer, the frozen body storage body is turned upside down and the frozen body is taken out from the upper opening of the frozen body storage body while vacuuming. It is conceivable to load the frozen body into a dryer, but in this case, the work of turning the frozen body storage body upside down becomes complicated, and the frozen body melts and adheres to the upper portion of the side wall portion of the frozen body storage body. There is a risk of causing trouble.
In this way, the prepared frozen body can be easily taken out from the freezing low-temperature fluid in the freezing fluid tank, and the frozen body stored in the frozen body storage body can be easily loaded into the vacuum dryer. Therefore, it is possible to facilitate the work of transferring the frozen body in the low-temperature fluid for freezing to the vacuum dryer.
Moreover, since the side wall portion of the frozen body storage body is formed in a form having a non-porous and smooth inner surface, the liquid raw material is sprayed or sprayed on the freezing low-temperature fluid stored in the freezing fluid tank. When the frozen body is prepared by dropping, even if the frozen body is scattered toward the inner surface of the portion located above the low-temperature fluid for freezing in the side wall portion, the scattered frozen body is smooth on the side wall portion. Since it is possible to avoid adhering to the inner surface of the side wall portion and thawing, such as sliding down along the inner surface, a frozen body can be satisfactorily prepared.
In short, according to the characteristic configuration of the frozen body manufacturing apparatus of the present invention, it is possible to facilitate the work of transferring the frozen body in the low-temperature fluid for freezing to the vacuum dryer, and moreover, the frozen body can be satisfactorily prepared. it can.
In addition , when creating a frozen body, the freezing fluid tank mounted on the transport trolley is moved to the lower part of the fixedly arranged lid while the transport trolley is running, and then the freezing fluid tank is moved. Is lifted by the lifting operation by the transport trolley so that the lid is attached to the upper part of the freezing fluid tank.
