Description

  The present invention relates to a storage for storing sorbet-like ice having fluidity obtained from seawater, and particularly to a storage for storing sorbet-like ice having a solid ice content of 70% or less.

In recent years, sherbet-like ice obtained from seawater has been used in order to maintain the freshness of fish. Patent Document 1 discloses a method for producing sherbet-like ice from seawater.
However, there is no suitable means for storing such sherbet-like ice.
FIG. 10 is an example of a conventional solid ice storage without fluidity.
Since sherbet-like ice produced from seawater has different properties from non-fluid lump-like ice, various inconveniences have been caused by conventional ice storage means.
In the case of lumpy ice having no fluidity, a large number of small pieces of ice are stored in the storage. In the storage, ice composed of small chunks may consolidate, but a means of destroying the consolidation and returning to small chunks of ice with an agitator (A) as shown in FIG. 10 is preferable. It is used for.
However, the sherbet-like ice is naturally integrated with moisture and fine ice pieces, and is not agglomerated when supplied to the storage. Furthermore, when sherbet-like ice made of seawater is left stationary for a long time, the ice components and water components easily separate, and the fine ice pieces solidify and consolidate, resulting in large ice pieces. Form. Therefore, it is not possible to adopt a means for returning to small ice again using the agitator (A).
Thus, when large ice is formed in the storage chamber, the ice is not suitably discharged from the storage.

Here, a case where sherbet-shaped ice is stored using a conventional solid ice storage will be described.
In the storage shown in FIG. 10, an agitator (A) that is rotatably installed inside the storage chamber (R) is disposed. The essential role of the agitator (A) is that when the agitator (A) rotates, the agitator rod (A1) extending from the central axis of the agitator (A) collides with ice in the storage chamber (R). This is to prevent the ice pieces from consolidating.
When a storage room having such an agitator (A) is applied to sherbet-like ice, the sherbet-like ice consolidates in the storage chamber to form a large lump of ice. Here, when the agitator (A) is rotated, since the ice forms a large mass so as to cover the agitator (A), the ice rotates with the agitator (A). Therefore, the ice is not reduced by the rotation of the agitator (A) and cannot be taken out from the discharge port.
Furthermore, since sherbet-shaped ice made of seawater is easily separated into water and ice components, if the discharge operation is performed while large ice cubes are formed, only the water components are discharged first, and the ice components are removed. It will be left in the storage room.
Therefore, what is removed from the storage chamber no longer has a sherbet-like ice body.

Hereinafter, embodiments of a sherbet-shaped ice storage according to the present invention will be described with reference to the drawings. Fig.1 (a) is the schematic of the storage of this invention. FIG.1 (b) is the figure which looked at the inside of the store | warehouse | chamber of this invention from the upper direction.
The storage (1) of the present invention has a substantially cylindrical storage chamber (11). The bottom surface portion (12) of the storage chamber (11) has a tapered shape that narrows downward. A lid (13) is disposed on the upper surface of the storage chamber (11). Between the bottom surface portion (12) and the lid portion (13), there is a cylindrical body portion (14).
The storage chamber (11) is connected to the motor (35) and is provided with a rotating shaft (31) that rotates about the center of the storage chamber (11). The storage chamber (11) extends in the radial direction. A baffle rod (33) extends from the inner wall of the storage chamber (11) so as to sandwich the surface defined by the rotation of the crushing rod (32) up and down.
The rotation shaft (31) may be rotated at least when the ice block is charged into the storage chamber (11) and when sherbet-shaped ice is discharged. Similarly, the supply pipeline (50) and the circulation pipeline (51) described below may be operated when the ice block is charged into the storage chamber (11) and when sherbet-shaped ice is discharged.

Outside the storage (1), sherbet-shaped ice supply / circulation means comprising a supply pipeline (50) and a circulation pipeline (51) is provided.
The supply pipeline (50) is connected to the input port (24), the input port (24), and is provided immediately below the input port (24). The supply pump (501), It consists of a supply pipe (503) that connects and connects to the upper surface of the storage chamber (11).
The sherbet-shaped ice charged from the charging port (24) is supplied into the storage (1) by the supply pump (501) via the supply pipe (503). By constructing the supply-dedicated pipeline (50) in this way, the output of the pump can be increased as necessary, and a system suitable for supply can be easily made.
In addition, since the bent pipe part, branch pipe part, or pipe line connection part in the supply pipeline (50) is easily consolidated, heaters are provided on the inlet side and the outlet side of the supply pump (501) to prevent this. Means are provided for preventing the sherbet-like ice from consolidating in the supply pipeline (50). Moreover, a heater may be provided in the required location in the supply pipeline (50) as needed. For example, a heater is arranged in a curved pipe part, a branch pipe part, or a pipe line connection part.
The supply pump (501) is provided with a water drain part (512) so that the water in the supply pump can be drained as appropriate.

The circulation pipeline (51) includes a circulation discharge pump (510) and a circulation pipe (511). The circulation pipe (511) is connected to the upper side surface of the storage (1) from the circulation discharge pump (510). In addition, a valve (512) is provided in the middle of the circulation pipe (511), and a branch portion that branches in the lateral direction is provided below the valve (512), and a discharge port (513) extends from the branch portion. Has been established. A valve (514) is further provided between the branch portion and the discharge port (513). By operating these valves (512, 514), the discharge from the circulation path and the circulation in the storage system are appropriately switched. Further, a valve is disposed between the pipe connecting the bottom of the storage (1) and the circulation discharge pump (510), and the valve is closed except during the circulation operation.
During circulation, the sherbet-like ice discharged from the bottom surface (12) of the storage (1) is returned again into the storage (1) through the circulation pipe (511) by the circulation discharge pump (510). When discharging, sherbet-like ice is discharged from the discharge port (513).
As shown in FIG. 1, the circulation discharge pump (510) is disposed immediately below the storage (1) so as to minimize the path from the storage (1) to the circulation discharge pump (510). This minimizes the pressure loss due to the conduit between the storage (1) and the circulation discharge pump (510), and maximizes the suction of the circulation discharge pump (510) to the ice discharge from the storage (1). This is to make it available to the limit. Thus, since the circulation pipeline (51) is constructed separately from the sherbet-shaped ice supply path, it is possible to appropriately set the arrangement and the like of the pump necessary for circulation. As the best mode, a mode in which the flow resistance is reduced as much as possible without using a curved pipe or the like between the circulation discharge pump (510) and the storage (1) is preferable. For example, the storage (1) is connected to the circulation discharge pipe (510) through only a straight pipe.
Similarly to the supply pipeline (50), a heater may be provided at a necessary portion of the circulation pipeline (51) to prevent the ice in the circulation path from consolidating. For example, by providing the circulation discharge pump (510) with a heater, it is possible to prevent the sherbet-like ice from consolidating in the curved pipe part, branch pipe part or pipe connection part in the middle of the circulation pipeline (51). It becomes possible. Or you may heat a curved pipe part, a branch pipe part, a pipe line connection part, etc. with a heater directly.
In addition, a drainage part (512) is provided below the storage (1) on the side facing the circulation discharge pump so that the water component of the sherbet-like ice can be appropriately discharged from the storage (1).
In the example shown in FIG. 1, the supply pipeline (50) and the circulation pipeline (51) are constructed using separate pipes (503, 512). It is good also as piping. For example, a supply pipe (503) extending from the supply pump (501) is connected to a circulation pipe (511). Thus, the space saving of the storage (1) can be achieved by conveying the supplied sherbet-like ice or circulating sherbet-like ice to the upper part of the storage (1) with one pipe. In this case, it is preferable that a valve is provided between the supply pump (501) and the connection portion so that the supply and circulation operations can be switched.

FIG. 2 shows another embodiment of the supply pipeline (50).
2 supplies a hopper (504) capable of temporarily storing a predetermined amount of sherbet-like ice produced by an ice making machine, and conveys the sherbet-like ice in the hopper (504) upward. It consists of a screw conveyor (505) and a motor (506) that rotates a screw (507) in the screw conveyor (505).
The screw conveyor (505) includes a shaft portion (508) and a screw (507) spirally formed along the shaft portion (508) in the pipe, and the shaft portion (508) includes a motor (506) and a gear. It is connected through.
The screw conveyor (505) branches in the middle, and the branch (509) communicates with the upper surface of the storage (1). In addition, the branch part (509) is located above the storage (1) upper surface.
The sherbet-shaped ice stored in the hopper (504) is conveyed upward by the rotation of the screw (507) of the screw conveyor (505). The sherbet-like ice that has reached the branch portion of the screw conveyor (505) naturally falls through the branch portion (509) and is supplied into the storage (1).
According to such a supply pipeline (50), it is not supplied by the pressure difference of the fluid created by the pump, but is transported physically and mechanically by a screw, so a high IPF (Ice Packing Factor), Particularly, it is suitable for supplying ice having a low fluidity of IPF of about 45% or more. Here, IPF (Ice Packing Factor) is an index indicating the characteristics of the sherbet-like ice, and indicates the ratio of solid ice components in the sherbet-like ice. When the IPF reaches 100%, the liquid component is included. No, it becomes powdery ice. Also, the higher the IPF, the lower the fluidity of the sherbet ice.
In the storage of the present invention, sherbet-like ice having an IPF of 70% or less is preferably used. This is because if the IPF is 70% or less, sufficient fluidity can be secured in the storage of this embodiment.

FIG. 3 shows another embodiment of the circulation pipeline (51). FIG. 3A is a front view of the circulation pipeline (51) and the storage (1), and FIG. 3 (b) is a plan view.
The circulation pipeline (51) is branched into four paths immediately before reaching the storage (1), and the four connections between the storage (1) and the branch path are substantially parallel in one storage (1) horizontal section. They are evenly arranged to draw a square. Each path enters the storage (1) toward the side of the square, and sherbet-like ice from each path flows along the wall surface of the storage chamber (11).
Furthermore, each path is provided with a valve so that the flow rate of the sherbet-like ice flowing through each path can be appropriately adjusted.
When the circulation pipeline (51) is constructed in this way, a rotating flow can be generated by the flow of the sherbet-like ice flowing from the circulation pipeline (51) inside the storage (1). Thereby, the fluidity of the ice inside the storage (1) can be reliably ensured during the circulation operation. Further, by adjusting the valve, the flow form of the rotating flow can be changed, and an optimum rotating flow can be realized.
In the example shown in the figure, the embodiment is divided into four. However, the number is not limited, and may be one or more connection points. For example, five or six can be appropriately designed. . In addition, in the form of 1 or 2 connection points, it is preferable to arrange the branch pipe so that the sherbet-like ice flowing from the branch pipe flows along the inner wall surface of the storage chamber (11). This is because a rotational flow parallel to the horizontal cross section of the storage room can be obtained over the entire storage room.
In addition, it is preferable that the heat insulating material is stretched over the outer peripheral surface of the said storage (1), a supply pipeline (50), and a circulation pipeline (51). Thereby, the heat retention of the sherbet-like ice of the present invention is appropriately performed.

A crushing / stirring mechanism is provided inside the storage chamber (11). The crushing / stirring mechanism includes a rotating shaft (31) disposed on the central axis of the storage chamber (11), a crushing rod (32) extending from the rotating shaft (31), and an inner wall of the storage chamber (11). A rotating shaft (31) for rotating a baffle bar or baffle plate (33) extending toward the center, a stirring blade (34) disposed at the lower end of the rotating shaft (31), and the rotating shaft (31). It consists of a motor part (35) connected to the upper end and installed on the upper surface of the lid part (13).
Here, the baffle rod means a rod body having a circular cross section, and the baffle plate means a rod body having a rectangular cross section. Hereinafter, these are collectively referred to as a baffle stick.

In this embodiment, six crushing bars (32) extend from the rotation shaft (31). The crushing rods (32) are alternately arranged on the left and right along the rotation axis (31). That is, the angle is 180 ° in a plan view formed by adjacent crushing bars (32) (see FIG. 1B). In this way, by arranging the crushing bars (32) symmetrically and alternately in the axial direction, the crushing action can be brought about on the sherbet-like ice in the storage chamber (11) as a whole.
In addition, it is preferable that the length of the crushing rod (32) is formed so that the tip of the crushing rod (32) extends to the vicinity of the inner wall of the storage chamber (11). In this way, the sherbet-like ice in the vicinity of the wall surface of the storage chamber (11) can be crushed.

  In this embodiment, 20 baffle bars (33) extend from the body (14) of the storage chamber (11). The baffle rod (33) is divided into four groups, and each group is arranged so as to be divided at a central angle of 90 ° in a plan view of the cross section of the storage chamber (11) (see FIG. 1B). The baffles (33) of each group are aligned in a line in the axial direction of the storage chamber (11). Further, the baffle rods (33) of each group arranged in the axial direction are arranged at the same height in the axial direction of the storage chamber (11).

The sherbet-shaped ice is consolidated in the storage chamber (11) to form a large lump of ice. At this time, the crushing rod (32) and the baffle rod (33) are stuck into the ice block.
By the rotational force of the rotating shaft (31), the crushing rod (32) generates a force in the ice block in the rotating direction of the rotating shaft (31). On the other hand, the baffle rod (33) generates a reaction force against the rotational force. Accordingly, a shearing force is generated inside the ice block, cracks (fine cracks) are generated inside the ice block from the crushing rod (32) and the baffle rod (33), and the ice block is broken into fine ice pieces. As a result, the solidified ice turns into sherbet-like ice again.
The baffle rod (33) is preferably formed so that its tip reaches the vicinity of the rotation shaft (31). In this way, the ice near the rotating shaft (31) can be reliably crushed.
Moreover, the shape of the crushing rod (32) and the baffle rod (33) is not particularly limited, and may be a circular cross section or a rectangular cross section. If the crushing bar (32) and the baffle bar (33) have a circular cross section, the crushing bar (32) and the baffle bar (33) are structurally strong against the bending force generated by the crushing operation of ice. The risk that the crushing bar (32) and the baffle bar (33) break or bend can be reduced. If the crushing rod (32) and the baffle rod (33) having a rectangular cross section are used and the corners of the cross section are directed in the rotation direction, cracks are easily generated in the ice block.

FIG. 4 shows another embodiment of the crushing rod (32).
As shown in FIG. 4, the wing part (6) formed in an S shape in front view along the length of approximately half of the crushing bar (32) from the root part of the crushing bar (32) and having curved surfaces up and down. It may be formed. By forming the wings (6) in this way, the flow in the upward or downward direction in the direction of the central axis of the storage (1) is accompanied by the rotation by the motor (35) disposed on the upper surface of the storage (1). Can be formed. Further, the direction of flow can be changed by changing the rotation direction of the motor (35).
Therefore, in the embodiment shown in FIG. 4, a rotating flow parallel to the vertical section of the storage (1) can be formed. In addition, by combining the embodiment shown in FIG. 3, it is possible to combine rotational flows parallel to the vertical section and horizontal section of the storage (1), and to form a complicated flow inside the storage (1), Since the flow can reach the inside of the storage (1), a more suitable circulation action can be obtained.

The stirring blade portion (34) is disposed at an axially intermediate position of the conical space formed by the bottom surface portion (12) of the storage chamber (11). The stirring blade portion (34) is a flat plate, and the lower surface thereof is inclined toward the rotation direction and disposed at the lower end of the rotation shaft (31). The stirring blade part (34) rotates with the rotation of the rotating shaft (31), and pushes out sherbet-like ice below the stirring blade part (34). The pushed sherbet-shaped ice is sent out from the taper end of the bottom surface portion (12) of the storage chamber (11) to the pipeline (21).
As the stirring blade part (34) rotates, the sherbet-like ice is sent downward, so that the sherbet ice can be sent out from the storage chamber (11) well, and the circulation action of the sherbet-like ice is also good. Can be encouraged.

  A temperature measuring means (4) may be provided on the inner wall of the storage chamber (11). In this embodiment, a resistance temperature detector is used. The rotational speed of the motor unit (35) may be increased or decreased according to the output signal of the temperature measuring means (4). For example, it is preferable to increase the rotational speed of the motor unit (35) when the temperature falls below a reference value, and to force the sherbet-like ice to flow in accordance with the rise in the IPF of the sherbet-like ice. . In this way, the crushing rod (32) can be rotated at an optimum number of rotations according to the temperature or viscosity of the sherbet-like ice, and the discharge of good sherbet-like ice can be promoted.

Next, the usage form of the storage having the structure shown in FIG. 1 will be described below.
The sherbet-shaped ice is introduced from the inlet (24). Thereafter, the sherbet-shaped ice charged into the charging port (24) is conveyed to the feeding pump (502) by the supply pump (501). Thereafter, the sherbet-shaped ice is conveyed upward by the feed pump (502), and is supplied into the storage chamber (11) from the lid (13) on the upper surface of the storage chamber (11).
In the storage chamber (11), the rotating shaft (31) is normally stopped while sherbet-shaped ice is stored. When the ice is discharged from the storage chamber (11), the motor (35) operates to rotate the rotating shaft (31) and the portion connected thereto. Thus, the IPF is prevented from being lowered by operating the motor (35) only at the time of discharging.
In this state, the sherbet-like ice is in a stationary state, and the sherbet-like ice changes into large ice in the storage chamber (11).
When the motor (35) is operated, the ice block is crushed by the crushing rod (32) and the baffle rod (33) as described above to form a large number of fine ice pieces. Thereafter, the fine ice pieces and the water component are stirred and mixed by the rotation of the crushing rod (32) to form sherbet-like ice.
The sherbet-like ice is formed below the storage chamber (11) by the tapered shape of the bottom surface portion (12) of the storage chamber (11), the weight of the ice, the suction action of the stirring blade (34) and the circulation discharge pump (510). And is discharged from the storage room (11).
The sherbet-like ice discharged from the storage chamber (11) is returned again into the storage chamber (11) through the circulation pipe (511) by the circulation discharge pump (510).
In addition, it is possible to take out the sherbet-like ice in circulation from the discharge port of the circulation pipeline by operating the valve of the circulation pipeline (51).
Here, if the supply pipeline (50) shown in FIG. 2 is used, high IPF sherbet-like ice can be supplied to the storage (1), and the form of the circulation pipeline (51) shown in FIG. 3 can be used. For example, a rotating flow of sherbet-like ice parallel to the horizontal section in the storage chamber (11) can be generated, and if the crushing rod (32) shown in FIG. A rotating flow of parallel sherbet-like ice can be generated. Furthermore, by combining the embodiments of FIG. 3 and FIG. 4, a more complicated flow form can be generated in the storage chamber (11), and the flow form of the sherbet-like ice during the circulation operation is further increased. Make it suitable.

Next, a modified example of the above structure is shown in FIG. In the embodiment shown in FIG. 5, a flat bar is used instead of the columnar or cylindrical crushing rod (32) of the storage shown in FIG. The structure of the other parts is the same as that shown in FIG.
The crushing rod (321) shown in FIG. 5 has an inclination with the lower surface of the flat plate facing the rotation direction, similarly to the stirring blade portion (34). Moreover, from each crushing rod (321) attachment part on a rotating shaft (31), a pair of crushing rods (321) are extended right and left, and this pair of crushing rods (321) are rotating shafts (31). Are lined up in a row.
In the storage (1) having such a structure, after crushing the ice block, each crushing bar (321) stirs the sherbet-shaped ice and causes the sherbet-shaped ice to flow downward. Therefore, the circulation and discharge of the sherbet-like ice can be performed better.

FIG. 8 shows an example of means for more effectively discharging sherbet-like ice.
When sherbet ice made of seawater is stored in a stationary state in the storage chamber (11), it is separated into an ice component and a water component. For this reason, if it is going to discharge | emit, only a water component will be discharged | emitted from a storage chamber (11) previously. In such a case, the IPF of ice remaining in the storage chamber (11) becomes relatively high, and the discharge from the storage chamber (11) is not suitably performed.
In the embodiment shown in FIGS. 8 and 9, the water component discharged first from the storage chamber (11) is returned to the storage chamber (11) again, and the water component causes the water component at the bottom of the storage chamber (11) to be discharged. Means for improving the fluidity of the sherbet-like ice and obtaining a suitable discharging action are provided.
In the embodiment shown in FIG. 8, the branch pipeline (25) branched from the pipeline (21) extending from the bottom surface portion (12) of the storage chamber (11) is below the trunk portion (14) of the storage chamber (11).

When the sherbet-like ice in the storage chamber (11) is reduced, the discharge effect due to its own weight is reduced. In order to compensate for this, sherbet-like ice or water stored in the auxiliary storage chamber (27) is sprayed from the branch pipeline (25) toward the bottom surface (12) of the storage chamber (11). In this way, the fluidity of the sherbet-shaped ice deposited on the bottom surface portion (12) of the storage chamber (11) is increased by the jetted sherbet-shaped ice or water, and the stirring blade portion (34), the bottom surface portion The discharge of the sherbet-like ice is promoted by the tapered shape of (12) and the sherbet-like ice or water flow pressure ejected from the branch pipeline (25).
A plurality of branch pipelines (25) are preferably provided.

As a modification of the embodiment shown in FIG. 8, instead of circulating the sherbet-like ice in the branch pipeline (25), seawater or water may be introduced from the outside.
As described above, the sherbet-like ice is easily separated into the water component and the ice component, and if a large amount of the ice component collects at the discharge port of the storage chamber (11), the discharge may not be performed smoothly. In such a case, a smooth discharge action can be obtained by supplying water components from the outside, reducing the IPF of the sherbet-like ice in the taper space, and improving the fluidity.
Further, in this embodiment, a variable current is used so as to rotate the motor (35) at a constant speed, a means for measuring the current value of the motor (35) is provided, a load applied to the motor (35) is measured, An automatic control means for calculating the IPF of the sherbet-like ice from the load and appropriately controlling the flow rate of the water component from the outside so as to appropriately reduce the IPF may be provided.

FIG. 9 shows another embodiment using a branch pipeline (25). FIG. 9 (a) shows an embodiment for increasing the fluidity of sherbet-like ice around the stirring blade (34), and FIG. 9 (b) shows a modification of the embodiment of FIG. 9 (a). .
In the embodiment shown in FIG. 9, the difference from the embodiment shown in FIG. 5 is the position and orientation of the nozzle connected to the branch pipeline (25), and the other configurations are the same as those shown in FIG. .
In the embodiment of FIG. 9 (a), the nozzle is disposed directly below the rotating shaft (31). The nozzle is also facing upward.
Immediately below the rotating shaft (31), since the action provided by the stirring blade (34) is small, sherbet-like ice is likely to accumulate. In order to complement the action of the agitating blade (34), in the embodiment shown in FIG. 9 (a), a sherbet-like ice or water ejected from the branch pipeline (25) is used to directly below the rotating shaft (31). The sherbet-like ice is flowed and a good discharging action is obtained.
In this embodiment, the nozzle may be directed in the lateral direction. In this case, the fluidity of the whole ice in the bottom surface portion (12) of the storage chamber (11) is increased, and good discharge is performed.
9B, in addition to the embodiment shown in FIG. 9A, a substantially hemispherical dish (36) is disposed at the lower end of the rotating shaft (31) with its inner wall face downward. ing.
The dish portion (36) collides with the sherbet-like ice ejected from the branch pipeline (25), and the dish portion (36) bounces the sherbet-like ice downward toward the stirring blade portion (34). Make it. Accordingly, the sherbet-like ice convects and flows below the stirring blade part (34), and the circulation and fluidity of the sherbet-like ice near the discharge port below the storage chamber (11) are enhanced.
Note that by combining the embodiment shown in FIG. 9 and the embodiment shown in FIG. 8, the fluidity of the sherbet-like ice below the storage chamber (11) can be further enhanced.
Further, in the embodiment shown in FIG. 9, the branch pipeline (25) may be connected to an external water component supply source instead of branching from the pipeline (21) extending from the discharge port. If it does in this way, the IPF of the sherbet-like ice under the storage room (11) can be reduced suitably, and smooth discharge can be promoted.

As described above, various embodiments of the configuration of the present invention have been described, but it is needless to say that these can be combined as appropriate to achieve the present invention.
The example of the usage form of the storage of this invention which employ | adopted the structure of various embodiment shown above is shown.

During the circulation, the rotating shaft (31) is rotated to discharge ice from the storage chamber (11) while crushing the sherbet-like ice consolidated in the storage chamber (11). Based on the form shown in FIG. 8 or FIG. 9, the water component of the sherbet-like ice discharged from the storage chamber (11) first is removed by the branch pipeline (25) to the sherbet-like ice at the bottom of the storage chamber (11). It is preferable to enhance fluidity and promote smooth discharge. If the fluidity of the ice at the bottom of the storage chamber (11) is enhanced and the solidified ice component floats above the storage chamber, the circulation pump (510) is operated, and sherbet-like ice with high fluidity is stored in the storage chamber. (11) While returning to the upper side, the frozen ice component having low fluidity is brought to the lower side of the storage chamber (11), and further, the frozen ice component is flowed by the embodiment shown in FIG. 8 or FIG. Can be increased. By repeating this sequentially, the entire ice in the storage (1) becomes sherbet-like ice having uniform fluidity. Thus, after the fluidity of the sherbet-like ice becomes uniform, the homogeneous sherbet-like ice can be taken out from the discharge port (513) provided in the circulation path.
The above use examples are illustrative, and it is needless to say that any of the examples shown in the present specification may be adopted.
