Description

  TECHNICAL FIELD The present invention relates to a frozen body manufacturing apparatus that sprays or drops a liquid raw material toward a freezing cryogenic fluid stored in a bottomed tubular freezing fluid tank to create a granular or droplet-shaped frozen body.

  A frozen body produced by such a frozen body manufacturing apparatus is generally freeze-dried by a vacuum dryer, and fine powder is produced by the freeze-vacuum drying. That is, the frozen body manufacturing apparatus manufactures a frozen body for producing a 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 low temperature freezing fluid (n-hexane at −30 ° C.) stored in a freezing fluid tank (container). There is a method in which a frozen body (ice droplet) is created (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 the vacuum dryer, the frozen body (ice droplets) precipitated in the cryogenic fluid for freezing (ice droplets) is transferred. ) Is transferred to a stainless steel pad. Then, the pad on which the frozen body (ice droplets) is placed is placed inside a vacuum dryer and freeze-dried to produce fine powder.

Japanese Patent Laid-Open No. 2-43943

In Patent Document 1, the frozen body (ice droplets) precipitated in the cryogenic fluid for freezing is transferred to a pad, and the pad on which the frozen body (ice droplets) is placed is loaded in a vacuum dryer. The frozen body (ice drops) inside will be transferred to a vacuum dryer.
However, in order to remove the frozen body (ice droplets) precipitated in the freezing cryogenic fluid and transfer it to the pad, for example, It is troublesome and complicated to remove frozen bodies (ice droplets) precipitated in the cryogenic freezing fluid from the cryogenic freezing fluid by, for example, transferring them to a pad while scooping them with a net-like body.

  Therefore, the frozen body (ice droplets) in the cryogenic fluid for freezing is caused due to the troublesome and complicated work of taking out the frozen body (ice droplets) precipitated in the cryogenic fluid for freezing from the cryogenic fluid for freezing. Since the work of transferring C. to a vacuum dryer is a troublesome and complicated work, improvement has been desired.

  The present invention has been made in view of the above circumstances, and an object thereof is to facilitate the work of transferring a frozen body in a cryogenic cryogenic fluid to a vacuum dryer, and to freeze the frozen body. The point is to provide a frozen body manufacturing apparatus capable of producing a body satisfactorily.

The frozen body manufacturing apparatus of the present invention sprays or drops a liquid raw material toward a cryogenic low temperature fluid stored in a bottomed cylindrical freezing fluid tank to create a granular or drop-shaped frozen body. And its characteristic structure is
A bottomed tubular shape in which the bottom wall portion is formed into a porous shape that cannot pass through the frozen body and can pass the freezing cryogenic fluid, and the side wall portion is formed into a shape having a non-porous and smooth inner surface. The frozen body container is detachably mounted on the freezing fluid tank in a state where the bottom wall portion side portion is immersed in the freezing low temperature fluid, and is detachably provided above the freezing fluid tank,
The bottom wall portion of the frozen body container is configured to be openable and closable for taking out the frozen body ,
The frozen body container includes a bag-shaped body formed by textile-processing a fibrous material, and a tubular body disposed inside the bag-shaped body to form the side wall portion. At the bottom side portion located below the tubular body, the bottom wall portion is formed.
A frozen body take-out opening is formed in the bottom portion of the bag-like body, and a fastener that is detachably attached to the bag-like body in a state in which the frozen body take-out opening is closed is provided. In point.

  That is, since the bottomed tubular frozen body container is attached to the freezing fluid tank in a state in which the bottom wall side portion is immersed in the freezing low temperature fluid, the frozen body stored in the freezing fluid tank is frozen. The frozen body created 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 container can be detached above the freezing fluid tank, the frozen body container should be frozen when removing the created frozen body from the freezing cryogenic fluid in the freezing fluid tank. The frozen body thus prepared can be easily taken out from the cryogenic fluid for freezing only by removing the frozen body above the working fluid tank.
When the frozen body container is detached above the freezing fluid tank, the freezing low temperature fluid inside the frozen body container passes through the bottom wall of the frozen body container and is discharged to the outside. .

  In addition, since the bottom wall of the frozen body container is configured to be openable and closable for taking out the frozen body, when loading the frozen body stored in the frozen body container into the vacuum dryer, By opening the bottom wall of the frozen body container, the frozen body stored in the frozen body container can be taken out from the bottom wall of the frozen body container 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 loading the frozen body stored in the frozen body storage body 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 may be possible to load it in a dryer, but in this case, the work of vertically inverting the frozen body container becomes complicated, and moreover, the frozen body melts and adheres to the upper side portion of the side wall portion of the frozen body container. There is a risk of causing trouble.

  In this way, it is possible to easily take out the created frozen body from the freezing cryogenic fluid in the freezing fluid tank and to load the frozen body stored in the frozen body storage body into the vacuum dryer. Therefore, it is possible to facilitate the work of transferring the frozen body in the cryogenic fluid for freezing to the vacuum dryer.

  Moreover, since the side wall portion of the frozen body container is formed to have a non-porous and smooth inner surface, the liquid raw material is sprayed or sprayed toward the freezing cryogenic fluid stored in the freezing fluid tank. When creating a frozen body by dripping, even if the frozen body scatters toward the inner surface of the portion located above the freezing cryogenic fluid in the side wall, the scattered frozen body has a smooth side wall. Since it is possible to prevent the inner surface of the side wall portion from being melted by adhering to the inner surface such as sliding down along the inner surface, the frozen body can be satisfactorily prepared.

  In short, according to the characteristic constitution of the frozen body manufacturing apparatus of the present invention, it is possible to facilitate the work of transferring the frozen body in the cryogenic fluid for freezing to the vacuum dryer, and furthermore, to prepare the frozen body satisfactorily. it can.

Further , the frozen body storage body includes a bag-shaped body formed by textile-processing a fibrous material, and a tubular body that is disposed inside the bag-shaped body and forms a side wall portion. Since the bottom side portion located below the bottom wall portion is configured to form the bottom wall portion, that is, the frozen body container is formed by combining the separately formed bag-like body and the tubular body. Therefore, it is possible to facilitate the production of the frozen body container.

  And since the bag-shaped body is formed by processing the textile material into a porous material, the size of the hole for passing the cryogenic fluid for freezing formed in the bag-shaped body, Since the size can be made sufficiently small, a frozen body having a sufficiently small size can be created.

  Further, the tubular body formed as a separate body from the bag-shaped body can be formed with a metal material such as stainless steel so that the surface is sufficiently smooth, and thus is stored in the freezing fluid tank. When creating a frozen body by spraying or dropping liquid raw material toward the cryogenic freezing fluid, even if the frozen body scatters toward the inner surface of the cylinder that functions as the side wall of the frozen body container It becomes easy to appropriately avoid that the frozen body adheres to the inner surface and melts.

  In addition, a frozen body take-out opening is formed in the bottom side portion of the bag-like body, and a fastener that is detachably attached to the bag-like body in a state where the frozen body take-out opening is closed is provided. When the frozen body stored in the bag is taken out for loading into the vacuum dryer, the fastener is removed and the frozen body take-out opening is opened to store it in the bag. Since the frozen body thus stored can be discharged through the frozen body taking-out opening, the frozen body stored in the bag-like body can be taken out well.

  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 create a frozen body of a sufficiently small size, Moreover, it is possible to appropriately avoid the frozen body from adhering to the inner surface of the side wall portion and melting, and it is possible to favorably 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-like body in a non-floating manner.

  That is, the bottom side portion of the bag-shaped body may float when immersed in the cryogenic cryogenic fluid, but the lower end of the tubular body presses the bottom-side portion of the bag-shaped body in a non-floating manner, Since the bottom side portion of the bag-shaped body is prevented from rising, the bottom-side portion of the bag-shaped body can be maintained in an appropriate state immersed in the cryogenic cryogenic fluid.

  In this way, since it is possible to appropriately maintain the bottom side portion of the bag-shaped body immersed in the freezing cryogenic fluid, the bottom side portion of the bag-shaped body immersed in the freezing cryogenic fluid is created. The frozen body can be more favorably prepared 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 favorably.

  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 frozen body removal opening.

  That is, since the bottom side portion of the bag-like body is formed in a tapered shape that becomes thinner toward the frozen body taking-out opening, the frozen body stored in the bag-like body is discharged through the frozen body taking-out opening. At this time, the frozen bodies stored in the bag-shaped body are stored in the bag-shaped body because the frozen bodies can be discharged through the frozen-body removal opening while being gathered together in the formation portion of the frozen body removal opening. The frozen body can be taken out even better.

  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 favorably.

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

  That is, the bag-shaped body formed by weaving a fibrous material penetrates into the weight of the frozen body and the inside of the bag-shaped body when it is removed (taken out) upward from the freezing fluid tank. The weight of the cryogenic freezing fluid may cause damage such as tearing, but the bag-shaped body is housed inside a tubular protective body with a bottom that is formed into a porous shape to allow the bag-shaped body to move outward. The bag-like body can be prevented from being damaged by the protective body so that the bag-shaped body is prevented from spreading.

  Therefore, if the protective body is made of a metal material such as stainless steel so as to have sufficient strength, the frozen body can be suppressed while suppressing damage to the bag-shaped body even if the bag-shaped body is not provided with high strength. Can be satisfactorily created.

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

The frozen body manufacturing apparatus of the present invention sprays or drops a liquid raw material toward a cryogenic low temperature fluid stored in a bottomed cylindrical freezing fluid tank to create a granular or drop-shaped frozen body. And its characteristic structure is
A bottomed tubular shape in which the bottom wall portion is formed into a porous shape that cannot pass through the frozen body and can pass the freezing cryogenic fluid, and the side wall portion is formed into a shape having a non-porous and smooth inner surface.

The frozen body created 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 container can be detached above the freezing fluid tank, the frozen body container should be frozen when removing the created frozen body from the freezing cryogenic fluid in the freezing fluid tank. The frozen body thus prepared can be easily taken out from the cryogenic fluid for freezing only by removing the frozen body above the working fluid tank.
When the frozen body container is detached above the freezing fluid tank, the freezing low temperature fluid inside the frozen body container passes through the bottom wall of the frozen body container and is discharged to the outside. .
In addition, since the bottom wall of the frozen body container is configured to be openable and closable for taking out the frozen body, when loading the frozen body stored in the frozen body container into the vacuum dryer, By opening the bottom wall of the frozen body container, the frozen body stored in the frozen body container can be taken out from the bottom wall of the frozen body container 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 loading the frozen body stored in the frozen body storage body into the vacuum dryer, the frozen body storage body is turned upside down, and while the frozen body is taken out from the upper opening of the frozen body storage body, the vacuum It may be possible to load it in a dryer, but in this case, the work of vertically inverting the frozen body container becomes complicated, and moreover, the frozen body melts and adheres to the upper side portion of the side wall portion of the frozen body container. There is a risk of causing trouble.
In this way, it is possible to easily take out the created frozen body from the freezing cryogenic fluid in the freezing fluid tank and to load the frozen body stored in the frozen body storage body into the vacuum dryer. Therefore, it is possible to facilitate the work of transferring the frozen body in the cryogenic fluid for freezing to the vacuum dryer.
Moreover, since the side wall of the frozen body container is formed to have a non-porous and smooth inner surface, the liquid raw material is sprayed or sprayed toward the cryogenic low temperature fluid stored in the freezing fluid tank. When creating a frozen body by dripping, even if the frozen body scatters toward the inner surface of the portion located above the freezing cryogenic fluid in the side wall, the scattered frozen body has a smooth side wall.
