- the ice making apparatus 1 shown in FIG. 1 is an apparatus for producing flaky ice (hereinafter referred to as “flake ice 91”) by freezing brine B to form ice 9 and scraping the ice 9 thinly.
- the ice making device 1 includes an ice making plate 2, a cooling unit 3 for cooling the ice making plate 2, a brine supply unit 4 for supplying the brine B to the ice making plate 2, and a scraping unit for scraping the ice 9 formed on the ice making plate 2. It has a drive unit 6 for moving the brine supply unit 4 and the scraping unit 5 in the X-axis direction indicated by an arrow, and a collection unit 7 for collecting the flake ice 91 scraped by the scraping unit 5.
- the brine B is a liquid that is a raw material for the flake ice 91, and any brine B may be used according to the purpose of use of the flake ice 91.
- Examples of the brine B include water such as tap water, pure water, and mineral water, salt water such as saline solution and seawater, and a solution obtained by mixing functional chemicals such as germs and additives with water.
- the use of the flake ice 91 produced by the ice making device 1 is not particularly limited, but for example, fish such as hydrangea, mackerel, yellowtail, and tuna, shellfish such as abalone, mackerel, and clams, and shellfish such as crab and shrimp. Can be suitably used for cooling and preserving seafood (cooled matter). Since the flake ice 91 has a large specific surface area, it is possible to quickly cool the object to be cooled. Therefore, it is possible to keep the cold object to be cooled for a long time while maintaining the freshness of the cold object.
- the ice making plate 2 has a plate shape and is made of, for example, stainless steel. Further, the lower surface of the ice making plate 2 is the ice making surface 21, and the ice 9 is formed on the ice making surface 21 by freezing the brine B supplied to the ice making surface 21.
- the ice making surface 21 is composed of a flat surface and is arranged horizontally. In addition to the case where the "horizontal" is the same as the horizontal, for example, when there is a slight deviation from the horizontal that may occur in manufacturing or installation, the term “horizontal" is technically common sense. It means to include things that can be equated.
- the ice making plate 2 is formed with a plurality of through holes 22 penetrating the side surfaces 2a and 2b facing each other.
- the plurality of through holes 22 each have a linear shape extending in the same direction (X-axis direction), and are arranged at equal pitches in a direction orthogonal to the extending direction (Y-axis direction). By making each through hole 22 linear, the through hole 22 can be easily formed by a drill or the like.
- the refrigerant C supplied from the cooling unit 3 circulates in each through hole 22, and the ice making surface 21 is cooled by the refrigerant C.
- a plurality of connecting pipes 23 for connecting the ends of adjacent through holes 22 are mounted, and the plurality of through holes 22 are connected in a bellows shape by these connecting pipes 23. Therefore, one refrigerant flow path 20 is formed by the plurality of through holes 22 and the plurality of connecting pipes 23, and the refrigerant C is circulated in the refrigerant flow path 20 to uniformly cool the entire ice making surface 21. Can be done.
- the refrigerant C is not particularly limited, and for example, an antifreeze solution such as ethylene glycol or LNG (liquefied natural gas) can be used.
- a temperature sensor may be provided in the ice making plate 2 and the driving of the cooling unit 3 may be controlled based on the output from the temperature sensor to control the temperature of the ice making surface 21.
- the connecting pipe 23 is removable from the ice making plate 2, and the mounting location can be freely selected. Therefore, the refrigerant flow path 20 can be freely formed, and for example, as shown in FIG. 3, two refrigerant flow paths 201 and 202 can be formed. According to this configuration, by changing the type and flow rate of the refrigerant C between the refrigerant flow path 201 and the refrigerant flow path 202, the cooling temperatures can be made different from each other, and the ice making surface 21 can be given a temperature distribution. .. That is, the cooling unit 3 can independently cool the region T1 that overlaps the refrigerant flow path 201 and the region T2 that overlaps the refrigerant flow path 202 on the ice making surface 21. Therefore, it is possible to simultaneously produce ice 9 having different degrees of freezing in the regions T1 and T2.
- the through hole 22 and the connecting pipe 23 are not limited to the illustrated configuration.
- the number of through holes 22 may be one to seven, or nine or more, in addition to the eight shown in the figure.
- each through hole 22 may extend in the Y-axis direction orthogonal to the X-axis direction, which is the moving direction of the cutting portion 5, and is oblique with respect to the X-axis and the Y-axis. It may extend in the direction.
- at least one through hole 22 among the plurality of through holes 22 may extend in different directions with respect to the other through holes 22, or may be curved or bent in the middle thereof.
- the through hole 22 may be omitted and the ice making surface 21 may be cooled by another means.
- the connecting pipe 23 may be configured to connect three or more through holes 22 to each other, or may be configured to connect two not adjacent through holes 22 to each other.
- the ice making surface 21 is divided into two regions T1 and T2, but the number of regions is not particularly limited and may be three or more. Further, when the ice making surface 21 is divided into a plurality of regions, the arrangement thereof is not particularly limited, and the ice making surface 21 may be arranged in a line in the X-axis direction or the Y-axis direction, or may be arranged in a row in the X-axis direction and the Y-axis direction. They may be arranged in a matrix in the direction.
- a brine supply portion 4 for supplying the brine B to the ice making surface 21 and a cutting portion 5 for scraping the ice 9 formed on the ice making surface 21 are arranged. ing.
- the brine supply unit 4 has a nozzle 41 that allows the brine B to flow out.
- the nozzle 41 can move in the X-axis direction with respect to the ice making surface 21.
- the nozzle 41 has a plurality of outlets 411 arranged in a line in the Y-axis direction orthogonal to the X-axis direction which is the moving direction. Each outlet 411 faces upward in the vertical direction and faces the ice making surface 21.
- the configuration of the nozzle 41 is not limited to the configuration shown in the drawing, and may be, for example, a configuration having one line-shaped outlet 411 extending in the Y-axis direction.
- a gap G1 is provided between the outlet 411 and the ice making surface 21.
- a small amount of brine B flows out from the outflow port 411, and the outflowing brine B is held on the outflow port 411 by its own surface tension and comes into contact with the ice making surface 21, and is cooled by the ice making surface 21 to become ice 9.
- the planar ice 9 is produced on the ice making surface 21 by moving the nozzle 41 in the X-axis direction while flowing out the brine B from each outlet 411. At this time, even if the brine B is not forcibly discharged from the outlet 411 by using a pump or the like, the brine B continues to flow out from the outlet 411 due to the surface tension of the brine B.
- the brine B since the brine B is held on the outlet 411 by surface tension, the brine B is less likely to drip from the nozzle 41 and the ice making surface 21, and waste of the brine B can be prevented. Further, since the brine B is hard to hang down, it is not necessary to provide a mechanism for collecting the dripping brine B, and the collected brine B is not reused, so that it is not necessary to take measures against contamination of the brine B at the time of recovery. .. Therefore, the device can be simplified, downsized, and the cost can be reduced, and the ice 9 having high safety can be formed.
- the brine B is more homogeneous on the ice making surface 21 than when it is attached to the ice making surface 21 by jetting (spraying). It is possible to form ice 9 having a large thickness and having few surface irregularities. Therefore, by scraping off the ice 9 on the ice making surface 21, a homogeneous and high-quality flake ice 91 can be produced.
- the ice making surface 21 is a horizontal plane, it is possible to prevent the brine B supplied to the ice making surface 21 from moving on the ice making surface 21 due to its own weight.
- the thickness of the ice 9 on the ice making surface 21 is unlikely to vary, and flake ice 91 having a more uniform thickness can be manufactured. Further, since the outlet 411 faces upward in the vertical direction, more brine B can be held on the outlet 411. Therefore, ice 9 having a sufficient thickness can be formed on the ice making surface 21.
- the configuration of the brine supply unit 4 is not particularly limited as long as the brine B can be supplied to the ice making surface 21, and the brine B is forcibly discharged from the outlet 411 using, for example, a pump, a valve, or the like. May be good. Further, the brine B may be jetted and supplied to the ice making surface 21.
- the scraping section 5 has a blade 51 that scrapes the ice 9 formed on the ice making surface 21.
- the blade 51 is movable in the X-axis direction with respect to the ice making surface 21. Further, the blade 51 extends in the Y-axis direction orthogonal to the X-axis direction, which is the moving direction thereof, and its upper end 511 faces the ice making surface 21 and is in contact with the ice making surface 21 in the illustrated configuration.
- the upper end 511 may be separated from the ice making surface 21, and in this case, the gap between the upper end 511 and the ice making surface 21 is set to be smaller than the thickness of the ice 9 on the ice making surface 21.
- the ice 9 on the ice making surface 21 is scraped off by the blade 51, and the scraped ice 9 becomes flake-shaped flake ice 91 and falls.
- the scraped flake ice 91 freely falls, so that the flake ice 91 can be prevented from staying on the ice making surface 21. Therefore, the productivity of the flake ice 91 is increased. Further, the flake ice 91 remaining on the ice making surface 21 can hinder the supply of the brine B to the ice making surface 21 next time, and prevent the formation of inhomogeneous ice 9 on the ice making surface 21.
- the collection unit 7 has a box-shaped container 71 for storing and collecting flake ice 91 that has freely fallen from the ice making surface 21.
- the container 71 is located below the ice making surface 21 in the vertical direction, and the scraped flake ice 91 is collected in the container 71.
- a uniform amount of flake ice 91 is scraped from the entire area of the ice making surface 21, so that the flake ice 91 is uniformly accumulated over the entire area of the container 71. In other words, a part of it does not protrude like a mountain. Therefore, a large amount of flake ice 91 can be recovered by the container 71. Therefore, the productivity of the flake ice 91 is improved.
- the ice making device 1 has a stage 10 on which a nozzle 41 and a blade 51 are placed. Then, by moving the stage 10 in the X-axis direction, the nozzle 41 and the blade 51 move in the X-axis direction while maintaining a constant positional relationship with each other.
- the stage 10 is moved to the + side in the X-axis direction so that the nozzle 41 is located forward in the moving direction with respect to the blade 51.
- the brine B flows out from the nozzle 41 to form the ice 9 on the ice making surface 21, and the ice 9 formed on the ice making surface 21 can be scraped off by the blade 51 located behind the ice 9. Therefore, the ice 9 on the ice making surface 21 can be quickly scraped off by the blade 51, and the production capacity of the flake ice 91 is improved.
- the positional relationship between the nozzle and the blade 51 is constant during the movement of the stage 10, if the stage 10 is moved at a constant speed, the blade 51 is supplied with the brine B from the nozzle 41 to the ice making surface 21.
- the time T until it is scraped off can be kept constant. Therefore, a homogeneous flake ice 91 can be produced. Further, for example, by changing the moving speed of the stage 10 to control the time T, the water content of the ice 9 can be controlled, and the desired flake ice 91 can be produced.
- the configuration of the drive unit 9 is not limited to the configuration shown in the figure, and for example, the blade 51 and the nozzle 41 may be independently moved in the X-axis direction. As a result, the blade 51 and the nozzle 41 can be driven separately, and for example, the time T described above can be easily changed, and the characteristics of the flake ice 91 can be easily changed. Further, for example, the blade 51 and the nozzle 41 may be fixed and the ice making plate 2 may be moved in the X-axis direction, or the blade 51 and the nozzle 41 may be moved while moving the ice making plate 2 to one side in the X-axis direction. It may be moved to the other side in the X-axis direction. That is, any configuration may be used as long as the blade 51, the nozzle 41, and the ice making plate 2 can be relatively moved in the direction parallel to the ice making surface 21.
- the drive unit 6 moves the stage 10 in the X-axis direction.
- the drive unit 6 has a guide 61 that supports and guides the stage 10, and a drive source 62 that moves the stage 10 along the guide 61.
- the guide 61 has an oval shape and is located below the outward path 611 and the outward path 611 that guides the stage 10 to move in the X-axis direction + side, and guides the stage 10 to move in the X-axis direction ⁇ side. It has a return route 612.
- the stage 10 is guided by the guide 61 to move clockwise, and when the stage 10 is guided by the outward route 611 and moves to the + side in the X-axis direction, flake ice 91 is manufactured and guided to the return route 612.
- the production of the flake ice 91 is temporarily stopped. According to this configuration, by guiding the stage 10 with the guide 61 and looping the stage 10, the flake ice 91 can be repeatedly manufactured, and the productivity of the flake ice 91 is improved.
- the blade 51 does not come into contact with the ice making surface 21 while moving on the return path 612, and the ice making surface 21 and the blade 51 Damage can be prevented. Further, when moving on the return path 612, it is preferable to stop the outflow of the brine B so that the brine B does not hang down from the outlet 411.
- the guide 61 is arranged so as not to be located below the ice making surface 21. Specifically, when the region Q in which the ice making surface 21 is extended in the Z-axis direction is set, the guide 61 is located outside the region Q. As a result, it is possible to prevent the flake ice 91 scraped from the ice making surface 21 from adhering to the guide 61, and it is possible to suppress a decrease in the recovery rate of the flake ice 91.
- the ice making device 1 has a gap adjusting unit 8 for adjusting the gap G1 between the nozzle 41 and the ice making surface 21.

図1に示す製氷装置1は、ブラインBを凍られて氷9を形成し、氷9を薄く削り取ることで薄片状の氷(以下「フレーク氷91」と言う)を製造する装置である。製氷装置1は、製氷プレート2と、製氷プレート2を冷却する冷却部3と、製氷プレート2にブラインBを供給するブライン供給部4と、製氷プレート2に形成された氷9を削り取る削取部5と、ブライン供給部4と削取部5を矢印で示すX軸方向に移動させる駆動部6と、削取部5で削り取ったフレーク氷91を回収する回収部7と、を有する。ブラインBは、フレーク氷91の原料となる液体であり、フレーク氷91の使用目的に合わせて如何なるものを用いてもよい。ブラインBとしては、例えば、水道水、純水、ミネラルウォーター等の水や、食塩水、海水等の塩水や、水に雑菌剤等の機能性薬剤、添加物等を混ぜた溶液が挙げられる。 <First Embodiment>
Theice making apparatus 1 shown in FIG. 1 is an apparatus for producing flaky ice (hereinafter referred to as “flake ice 91”) by freezing brine B to form ice 9 and scraping the ice 9 thinly. The ice making device 1 includes an ice making plate 2, a cooling unit 3 for cooling the ice making plate 2, a brine supply unit 4 for supplying the brine B to the ice making plate 2, and a scraping unit for scraping the ice 9 formed on the ice making plate 2. It has a drive unit 6 for moving the brine supply unit 4 and the scraping unit 5 in the X-axis direction indicated by an arrow, and a collection unit 7 for collecting the flake ice 91 scraped by the scraping unit 5. The brine B is a liquid that is a raw material for the flake ice 91, and any brine B may be used according to the purpose of use of the flake ice 91. Examples of the brine B include water such as tap water, pure water, and mineral water, salt water such as saline solution and seawater, and a solution obtained by mixing functional chemicals such as germs and additives with water.
図1に示す製氷装置1は、ブラインBを凍られて氷9を形成し、氷9を薄く削り取ることで薄片状の氷(以下「フレーク氷91」と言う)を製造する装置である。製氷装置1は、製氷プレート2と、製氷プレート2を冷却する冷却部3と、製氷プレート2にブラインBを供給するブライン供給部4と、製氷プレート2に形成された氷9を削り取る削取部5と、ブライン供給部4と削取部5を矢印で示すX軸方向に移動させる駆動部6と、削取部5で削り取ったフレーク氷91を回収する回収部7と、を有する。ブラインBは、フレーク氷91の原料となる液体であり、フレーク氷91の使用目的に合わせて如何なるものを用いてもよい。ブラインBとしては、例えば、水道水、純水、ミネラルウォーター等の水や、食塩水、海水等の塩水や、水に雑菌剤等の機能性薬剤、添加物等を混ぜた溶液が挙げられる。 <First Embodiment>
The
製氷装置1で製造されるフレーク氷91の用途としては、特に限定されないが、例えば、あじ、さば、ぶり、マグロ等の魚類、あわび、さざえ、ハマグリ等の貝類、カニ、エビ等の甲殻類等の魚介類(被保冷物)を冷却保存するのに好適に用いることができる。フレーク氷91は、比表面積が大きいため、被保冷物を素早く冷却することができる。そのため、被保冷物の鮮度を保ちつつ、長時間にわたって被保冷物を保冷することができる。
The use of the flake ice 91 produced by the ice making device 1 is not particularly limited, but for example, fish such as hydrangea, mackerel, yellowtail, and tuna, shellfish such as abalone, mackerel, and clams, and shellfish such as crab and shrimp. Can be suitably used for cooling and preserving seafood (cooled matter). Since the flake ice 91 has a large specific surface area, it is possible to quickly cool the object to be cooled. Therefore, it is possible to keep the cold object to be cooled for a long time while maintaining the freshness of the cold object.
製氷プレート2は、板状をなし、例えば、ステンレス鋼で構成されている。また、製氷プレート2の下面が製氷面21となっており、製氷面21に供給されたブラインBが凍ることで製氷面21に氷9が形成される。製氷面21は、平坦面で構成され、水平に配置されている。なお、前記「水平」とは、水平と一致している場合の他にも、例えば、水平に対して製造上、設置上生じ得るわずかなずれが生じている場合等、技術常識的に水平と同視できるものを含む意味である。
The ice making plate 2 has a plate shape and is made of, for example, stainless steel. Further, the lower surface of the ice making plate 2 is the ice making surface 21, and the ice 9 is formed on the ice making surface 21 by freezing the brine B supplied to the ice making surface 21. The ice making surface 21 is composed of a flat surface and is arranged horizontally. In addition to the case where the "horizontal" is the same as the horizontal, for example, when there is a slight deviation from the horizontal that may occur in manufacturing or installation, the term "horizontal" is technically common sense. It means to include things that can be equated.
また、図2に示すように、製氷プレート2には、互いに対向する側面2a、2bを貫通する複数の貫通孔22が形成されている。複数の貫通孔22は、それぞれ、同じ方向(X軸方向)に延びる直線状をなし、延在方向に直交する方向(Y軸方向)に等ピッチに並んでいる。各貫通孔22を直線状とすることで、ドリル等により容易に貫通孔22を形成することができる。
Further, as shown in FIG. 2, the ice making plate 2 is formed with a plurality of through holes 22 penetrating the side surfaces 2a and 2b facing each other. The plurality of through holes 22 each have a linear shape extending in the same direction (X-axis direction), and are arranged at equal pitches in a direction orthogonal to the extending direction (Y-axis direction). By making each through hole 22 linear, the through hole 22 can be easily formed by a drill or the like.
各貫通孔22には冷却部3から供給される冷媒Cが循環し、この冷媒Cにより製氷面21が冷却される。図示の構成では、隣り合う貫通孔22の端部同士を連結する複数の連結パイプ23が装着されており、これら連結パイプ23によって複数の貫通孔22が蛇腹状に接続されている。そのため、複数の貫通孔22と複数の連結パイプ23で1本の冷媒流路20が形成され、この冷媒流路20に冷媒Cを循環させることで、製氷面21の全域を均一に冷却することができる。冷媒Cとしては、特に限定されず、例えば、エチレングリコール等の不凍液や、LNG(液化天然ガス)を用いることができる。
The refrigerant C supplied from the cooling unit 3 circulates in each through hole 22, and the ice making surface 21 is cooled by the refrigerant C. In the illustrated configuration, a plurality of connecting pipes 23 for connecting the ends of adjacent through holes 22 are mounted, and the plurality of through holes 22 are connected in a bellows shape by these connecting pipes 23. Therefore, one refrigerant flow path 20 is formed by the plurality of through holes 22 and the plurality of connecting pipes 23, and the refrigerant C is circulated in the refrigerant flow path 20 to uniformly cool the entire ice making surface 21. Can be done. The refrigerant C is not particularly limited, and for example, an antifreeze solution such as ethylene glycol or LNG (liquefied natural gas) can be used.
なお、例えば、製氷プレート2内に温度センサーを設け、この温度センサーからの出力に基づいて冷却部3の駆動を制御することにより、製氷面21の温度管理を行う構成となっていてもよい。
Note that, for example, a temperature sensor may be provided in the ice making plate 2 and the driving of the cooling unit 3 may be controlled based on the output from the temperature sensor to control the temperature of the ice making surface 21.
連結パイプ23は、製氷プレート2に着脱自在であり、装着場所を自由に選択することができる。そのため、冷媒流路20を自在に形成することができ、例えば、図3のように、2本の冷媒流路201、202を形成することもできる。この構成によれば、冷媒流路201と冷媒流路202とで冷媒Cの種類や流量を変えることにより、互いの冷却温度を異ならせることができ、製氷面21に温度分布を与えることができる。つまり、冷却部3は、製氷面21の冷媒流路201と重なる領域T1と冷媒流路202と重なる領域T2とをそれぞれ独立して冷却することができる。そのため、領域T1、T2で凍結度合いの異なる氷9を同時に製造することが可能となる。
The connecting pipe 23 is removable from the ice making plate 2, and the mounting location can be freely selected. Therefore, the refrigerant flow path 20 can be freely formed, and for example, as shown in FIG. 3, two refrigerant flow paths 201 and 202 can be formed. According to this configuration, by changing the type and flow rate of the refrigerant C between the refrigerant flow path 201 and the refrigerant flow path 202, the cooling temperatures can be made different from each other, and the ice making surface 21 can be given a temperature distribution. .. That is, the cooling unit 3 can independently cool the region T1 that overlaps the refrigerant flow path 201 and the region T2 that overlaps the refrigerant flow path 202 on the ice making surface 21. Therefore, it is possible to simultaneously produce ice 9 having different degrees of freezing in the regions T1 and T2.
なお、貫通孔22および連結パイプ23は、図示の構成に限定されない。例えば、貫通孔22は、図示の8本の他、1本~7本であってもよく、9本以上であってもよい。また、各貫通孔22は、削取部5の移動方向であるX軸方向ではなく、これと直交するY軸方向に延在していてもよく、X軸およびY軸に対して傾斜した斜め方向に延在していてもよい。また、複数の貫通孔22のうちの少なくとも1つの貫通孔22が他の貫通孔22に対して異なる方向に延在していてもよいし、その途中で湾曲または屈曲していてもよい。また、貫通孔22を省略し、別の手段で製氷面21を冷却してもよい。また、連結パイプ23は、3本以上の貫通孔22同士を連結する構成であってもよいし、隣り合わない2本の貫通孔22同士を連結する構成であってもよい。
The through hole 22 and the connecting pipe 23 are not limited to the illustrated configuration. For example, the number of through holes 22 may be one to seven, or nine or more, in addition to the eight shown in the figure. Further, each through hole 22 may extend in the Y-axis direction orthogonal to the X-axis direction, which is the moving direction of the cutting portion 5, and is oblique with respect to the X-axis and the Y-axis. It may extend in the direction. Further, at least one through hole 22 among the plurality of through holes 22 may extend in different directions with respect to the other through holes 22, or may be curved or bent in the middle thereof. Further, the through hole 22 may be omitted and the ice making surface 21 may be cooled by another means. Further, the connecting pipe 23 may be configured to connect three or more through holes 22 to each other, or may be configured to connect two not adjacent through holes 22 to each other.
また、図3の構成では、製氷面21が2つの領域T1、T2に分割されているが、領域の数は、特に限定されず、3つ以上であってもよい。また、製氷面21を複数の領域に分割する場合には、その配置も特に限定されず、X軸方向またはY軸方向に一列に並んで配置されていてもよいし、X軸方向およびY軸方向に行列状に配置されていてもよい。
Further, in the configuration of FIG. 3, the ice making surface 21 is divided into two regions T1 and T2, but the number of regions is not particularly limited and may be three or more. Further, when the ice making surface 21 is divided into a plurality of regions, the arrangement thereof is not particularly limited, and the ice making surface 21 may be arranged in a line in the X-axis direction or the Y-axis direction, or may be arranged in a row in the X-axis direction and the Y-axis direction. They may be arranged in a matrix in the direction.
図1に示すように、製氷プレート2の鉛直方向下側には、製氷面21にブラインBを供給するブライン供給部4と製氷面21に形成された氷9を削り取る削取部5が配置されている。
As shown in FIG. 1, on the lower side in the vertical direction of the ice making plate 2, a brine supply portion 4 for supplying the brine B to the ice making surface 21 and a cutting portion 5 for scraping the ice 9 formed on the ice making surface 21 are arranged. ing.
図4に示すように、ブライン供給部4は、ブラインBを流出させるノズル41を有する。ノズル41は、製氷面21に対してX軸方向に移動可能である。また、ノズル41は、移動方向であるX軸方向に直交するY軸方向に並んで一列に配置された複数の流出口411を有する。各流出口411は、鉛直方向上側を向き、製氷面21と向かい合っている。なお、ノズル41の構成は、図示の構成に限定されず、例えば、Y軸方向に延在するライン状の1つの流出口411を有する構成であってもよい。
As shown in FIG. 4, the brine supply unit 4 has a nozzle 41 that allows the brine B to flow out. The nozzle 41 can move in the X-axis direction with respect to the ice making surface 21. Further, the nozzle 41 has a plurality of outlets 411 arranged in a line in the Y-axis direction orthogonal to the X-axis direction which is the moving direction. Each outlet 411 faces upward in the vertical direction and faces the ice making surface 21. The configuration of the nozzle 41 is not limited to the configuration shown in the drawing, and may be, for example, a configuration having one line-shaped outlet 411 extending in the Y-axis direction.
また、流出口411と製氷面21との間にはギャップG1が設けられている。流出口411からは少量のブラインBが流出し、流出したブラインBは、自らの表面張力によって流出口411上に保持されると共に製氷面21と接触し、製氷面21で冷却されて氷9となる。そのため、各流出口411からブラインBを流出させつつ、ノズル41をX軸方向に移動することで、製氷面21上に面状の氷9が製造される。この際、ポンプ等を用いてブラインBを流出口411から強制的に流出させなくても、ブラインBの表面張力によって流出口411からブラインBが流出し続ける。
Further, a gap G1 is provided between the outlet 411 and the ice making surface 21. A small amount of brine B flows out from the outflow port 411, and the outflowing brine B is held on the outflow port 411 by its own surface tension and comes into contact with the ice making surface 21, and is cooled by the ice making surface 21 to become ice 9. Become. Therefore, the planar ice 9 is produced on the ice making surface 21 by moving the nozzle 41 in the X-axis direction while flowing out the brine B from each outlet 411. At this time, even if the brine B is not forcibly discharged from the outlet 411 by using a pump or the like, the brine B continues to flow out from the outlet 411 due to the surface tension of the brine B.
この方法によれば、ブラインBを表面張力により流出口411上に保持するため、ノズル41や製氷面21からブラインBが垂れ難くなり、ブラインBの無駄を防止できる。また、ブラインBが垂れ難いため、垂れたブラインBを回収する機構を設ける必要がなく、回収したブラインBを再使用することもないため、回収時のブラインBの汚染について対策を施す必要もない。したがって、装置の簡素化、小型化、低コスト化を図ることができ、かつ、安全性の高い氷9を形成することができる。
According to this method, since the brine B is held on the outlet 411 by surface tension, the brine B is less likely to drip from the nozzle 41 and the ice making surface 21, and waste of the brine B can be prevented. Further, since the brine B is hard to hang down, it is not necessary to provide a mechanism for collecting the dripping brine B, and the collected brine B is not reused, so that it is not necessary to take measures against contamination of the brine B at the time of recovery. .. Therefore, the device can be simplified, downsized, and the cost can be reduced, and the ice 9 having high safety can be formed.
また、表面張力を利用してブラインBを製氷面21に付着させて濡れ広げることにより、例えば、ブラインBを噴射(噴霧)により製氷面21に付着させる場合と比べて、製氷面21上に均質な厚さで、かつ、表面の凹凸も少ない氷9を形成することができる。そのため、製氷面21上の氷9を削り取ることで、均質で上質なフレーク氷91を製造することができる。特に、前述したように、製氷面21が水平面であるため、製氷面21に供給されたブラインBが自重によって製氷面21上を移動するのを抑制できる。そのため、製氷面21上の氷9に厚さばらつきが生じ難く、より均一な厚さのフレーク氷91を製造することができる。また、流出口411が鉛直方向上側を向くため、より多くのブラインBを流出口411上に保持することができる。そのため、製氷面21上に十分な厚さの氷9を形成することができる。
Further, by using the surface tension to attach the brine B to the ice making surface 21 to wet and spread it, for example, the brine B is more homogeneous on the ice making surface 21 than when it is attached to the ice making surface 21 by jetting (spraying). It is possible to form ice 9 having a large thickness and having few surface irregularities. Therefore, by scraping off the ice 9 on the ice making surface 21, a homogeneous and high-quality flake ice 91 can be produced. In particular, as described above, since the ice making surface 21 is a horizontal plane, it is possible to prevent the brine B supplied to the ice making surface 21 from moving on the ice making surface 21 due to its own weight. Therefore, the thickness of the ice 9 on the ice making surface 21 is unlikely to vary, and flake ice 91 having a more uniform thickness can be manufactured. Further, since the outlet 411 faces upward in the vertical direction, more brine B can be held on the outlet 411. Therefore, ice 9 having a sufficient thickness can be formed on the ice making surface 21.
ただし、ブライン供給部4の構成は、製氷面21にブラインBを供給することができれば、特に限定されず、例えば、ポンプ、バルブ等を用いて流出口411からブラインBを強制的に流出させてもよい。また、ブラインBを噴射して製氷面21に供給する構成であってもよい。
However, the configuration of the brine supply unit 4 is not particularly limited as long as the brine B can be supplied to the ice making surface 21, and the brine B is forcibly discharged from the outlet 411 using, for example, a pump, a valve, or the like. May be good. Further, the brine B may be jetted and supplied to the ice making surface 21.
削取部5は、製氷面21に形成された氷9を削り取るブレード51を有する。ブレード51は、製氷面21に対してX軸方向に移動可能である。また、ブレード51は、その移動方向であるX軸方向に直交するY軸方向に延在し、その上端511が製氷面21と対向し、図示の構成では接触している。なお、これに限定されず、上端511が製氷面21と離間していてもよく、この場合、上端511と製氷面21とのギャップは、製氷面21上の氷9の厚さよりも小さく設定される。
The scraping section 5 has a blade 51 that scrapes the ice 9 formed on the ice making surface 21. The blade 51 is movable in the X-axis direction with respect to the ice making surface 21. Further, the blade 51 extends in the Y-axis direction orthogonal to the X-axis direction, which is the moving direction thereof, and its upper end 511 faces the ice making surface 21 and is in contact with the ice making surface 21 in the illustrated configuration. Not limited to this, the upper end 511 may be separated from the ice making surface 21, and in this case, the gap between the upper end 511 and the ice making surface 21 is set to be smaller than the thickness of the ice 9 on the ice making surface 21. To.
ブレード51をX軸方向に移動させると、製氷面21上の氷9がブレード51によって削り取られ、削り取られた氷9は、フレーク状のフレーク氷91となって落下する。製氷面21を鉛直方向下側に向けることで、削り取られたフレーク氷91が自由落下するため、フレーク氷91が製氷面21に留まるのを防止することができる。そのため、フレーク氷91の生産性が高まる。また、製氷面21上に残存したフレーク氷91によって、次回の製氷面21へのブラインBの供給が阻害され、製氷面21に不均質な氷9が形成されるのを防止することもできる。また、氷9は、ブレード51で削り取られるとフレーク氷91となって速やかに落下するため、削り取られた後にブレード51に巻き込まれることがない。したがって、フレーク氷91の破壊を防止することができ、上質なフレーク氷91を生産することができる。
When the blade 51 is moved in the X-axis direction, the ice 9 on the ice making surface 21 is scraped off by the blade 51, and the scraped ice 9 becomes flake-shaped flake ice 91 and falls. By directing the ice making surface 21 downward in the vertical direction, the scraped flake ice 91 freely falls, so that the flake ice 91 can be prevented from staying on the ice making surface 21. Therefore, the productivity of the flake ice 91 is increased. Further, the flake ice 91 remaining on the ice making surface 21 can hinder the supply of the brine B to the ice making surface 21 next time, and prevent the formation of inhomogeneous ice 9 on the ice making surface 21. Further, when the ice 9 is scraped off by the blade 51, it becomes flake ice 91 and quickly falls, so that the ice 9 is not caught in the blade 51 after being scraped off. Therefore, it is possible to prevent the flake ice 91 from being destroyed and to produce high-quality flake ice 91.
図1に示すように、回収部7は、製氷面21から自由落下したフレーク氷91を貯留し回収する箱状の容器71を有する。容器71は、製氷面21の鉛直方向下側に位置しており、削り取られたフレーク氷91は、この容器71に回収される。なお、上述の方法によれば、製氷面21の全域から均一な量のフレーク氷91が削り取られることから、フレーク氷91が容器71の全域に均一に積もる。つまり、一部が山のように突出した状態とならない。したがって、容器71により多量のフレーク氷91を回収することができる。そのため、フレーク氷91の生産性が向上する。
As shown in FIG. 1, the collection unit 7 has a box-shaped container 71 for storing and collecting flake ice 91 that has freely fallen from the ice making surface 21. The container 71 is located below the ice making surface 21 in the vertical direction, and the scraped flake ice 91 is collected in the container 71. According to the above method, a uniform amount of flake ice 91 is scraped from the entire area of the ice making surface 21, so that the flake ice 91 is uniformly accumulated over the entire area of the container 71. In other words, a part of it does not protrude like a mountain. Therefore, a large amount of flake ice 91 can be recovered by the container 71. Therefore, the productivity of the flake ice 91 is improved.
図1に示すように、製氷装置1は、ノズル41およびブレード51を載置したステージ10を有する。そして、このステージ10をX軸方向に移動させることで、ノズル41とブレード51とが互いの位置関係を一定に保ったままX軸方向に移動する。なお、フレーク氷91を製造する際は、図6に示すように、ノズル41がブレード51に対して移動方向前方に位置するように、ステージ10をX軸方向+側に移動させる。これにより、ノズル41からブラインBを流出して製氷面21上に氷9を形成しつつ、その後方に位置するブレード51によって製氷面21に形成された氷9を削り取ることができる。そのため、製氷面21上の氷9を速やかにブレード51で削り取ることができ、フレーク氷91の生産能力が向上する。
As shown in FIG. 1, the ice making device 1 has a stage 10 on which a nozzle 41 and a blade 51 are placed. Then, by moving the stage 10 in the X-axis direction, the nozzle 41 and the blade 51 move in the X-axis direction while maintaining a constant positional relationship with each other. When manufacturing the flake ice 91, as shown in FIG. 6, the stage 10 is moved to the + side in the X-axis direction so that the nozzle 41 is located forward in the moving direction with respect to the blade 51. As a result, the brine B flows out from the nozzle 41 to form the ice 9 on the ice making surface 21, and the ice 9 formed on the ice making surface 21 can be scraped off by the blade 51 located behind the ice 9. Therefore, the ice 9 on the ice making surface 21 can be quickly scraped off by the blade 51, and the production capacity of the flake ice 91 is improved.
また、ステージ10の移動中は、ノズルとブレード51との位置関係が一定であるため、ステージ10を一定速度で移動させれば、ノズル41から製氷面21にブラインBが供給されてからブレード51に削り取られるまでの時間Tを一定に保てる。そのため、均質なフレーク氷91を製造することができる。また、例えば、ステージ10の移動速度を変更して時間Tを制御することで、氷9の水分含有率を制御でき、所望のフレーク氷91を製造することができる。
Further, since the positional relationship between the nozzle and the blade 51 is constant during the movement of the stage 10, if the stage 10 is moved at a constant speed, the blade 51 is supplied with the brine B from the nozzle 41 to the ice making surface 21. The time T until it is scraped off can be kept constant. Therefore, a homogeneous flake ice 91 can be produced. Further, for example, by changing the moving speed of the stage 10 to control the time T, the water content of the ice 9 can be controlled, and the desired flake ice 91 can be produced.
以上、駆動部9について説明したが、駆動部9の構成は、図示の構成に限定されず、例えば、ブレード51とノズル41とをそれぞれ独立してX軸方向に移動させてもよい。これにより、ブレード51とノズル41とを別々に駆動でき、例えば、前述した時間Tを変更し易くなり、フレーク氷91の特性を変化させ易い。また、例えば、ブレード51およびノズル41を固定して、製氷プレート2をX軸方向に移動させてもよいし、製氷プレート2をX軸方向の一方側に移動させつつ、ブレード51およびノズル41をX軸方向の他方側に移動させてもよい。つまり、ブレード51およびノズル41と製氷プレート2とを製氷面21と平行な方向に相対的に移動させることができれば、いかなる構成となっていてもよい。
Although the drive unit 9 has been described above, the configuration of the drive unit 9 is not limited to the configuration shown in the figure, and for example, the blade 51 and the nozzle 41 may be independently moved in the X-axis direction. As a result, the blade 51 and the nozzle 41 can be driven separately, and for example, the time T described above can be easily changed, and the characteristics of the flake ice 91 can be easily changed. Further, for example, the blade 51 and the nozzle 41 may be fixed and the ice making plate 2 may be moved in the X-axis direction, or the blade 51 and the nozzle 41 may be moved while moving the ice making plate 2 to one side in the X-axis direction. It may be moved to the other side in the X-axis direction. That is, any configuration may be used as long as the blade 51, the nozzle 41, and the ice making plate 2 can be relatively moved in the direction parallel to the ice making surface 21.
駆動部6は、ステージ10をX軸方向に移動させる。駆動部6は、ステージ10を支持すると共に案内するガイド61と、ガイド61に沿ってステージ10を移動させる駆動源62を有する。ガイド61は、オーバル状であり、ステージ10がX軸方向+側に移動するのを案内する往路611と、往路611の下方に位置し、ステージ10がX軸方向-側に移動するのを案内する復路612を有する。図示の構成では、ステージ10をガイド61に案内させて時計回りに移動させ、往路611に案内されてステージ10がX軸方向+側に移動する際にフレーク氷91を製造し、復路612に案内されてX軸方向-側に位置する際にはフレーク氷91の製造を一旦停止する。この構成によれば、ステージ10をガイド61で案内してループさせることで、フレーク氷91の製造を繰り返し行うことができ、フレーク氷91の生産性が向上する。
The drive unit 6 moves the stage 10 in the X-axis direction. The drive unit 6 has a guide 61 that supports and guides the stage 10, and a drive source 62 that moves the stage 10 along the guide 61. The guide 61 has an oval shape and is located below the outward path 611 and the outward path 611 that guides the stage 10 to move in the X-axis direction + side, and guides the stage 10 to move in the X-axis direction − side. It has a return route 612. In the illustrated configuration, the stage 10 is guided by the guide 61 to move clockwise, and when the stage 10 is guided by the outward route 611 and moves to the + side in the X-axis direction, flake ice 91 is manufactured and guided to the return route 612. When it is located on the-side in the X-axis direction, the production of the flake ice 91 is temporarily stopped. According to this configuration, by guiding the stage 10 with the guide 61 and looping the stage 10, the flake ice 91 can be repeatedly manufactured, and the productivity of the flake ice 91 is improved.
なお、往路611に対して、フレーク氷91の製造を行わない復路612を下方に配置することで、復路612を移動中にブレード51が製氷面21と接触しなくなり、製氷面21やブレード51の損傷を防止することができる。また、復路612を移動中のときは、流出口411からブラインBが垂れてしまわないように、ブラインBの流出を停止することが好ましい。
By arranging the return path 612, which does not manufacture the flake ice 91, below the outward path 611, the blade 51 does not come into contact with the ice making surface 21 while moving on the return path 612, and the ice making surface 21 and the blade 51 Damage can be prevented. Further, when moving on the return path 612, it is preferable to stop the outflow of the brine B so that the brine B does not hang down from the outlet 411.
また、図7に示すように、ガイド61は、製氷面21の下方に位置しないように配置されている。具体的には、製氷面21をZ軸方向に延長した領域Qを設定したとき、ガイド61は、領域Qの外側に位置している。これにより、製氷面21から削り取られたフレーク氷91がガイド61に付着してしまうのを抑制でき、フレーク氷91の回収率の低下を抑制することができる。
Further, as shown in FIG. 7, the guide 61 is arranged so as not to be located below the ice making surface 21. Specifically, when the region Q in which the ice making surface 21 is extended in the Z-axis direction is set, the guide 61 is located outside the region Q. As a result, it is possible to prevent the flake ice 91 scraped from the ice making surface 21 from adhering to the guide 61, and it is possible to suppress a decrease in the recovery rate of the flake ice 91.
また、製氷装置1は、ノズル41と製氷面21とのギャップG1を調整するギャップ調整部8を有する。ギャップ調整部8は、ノズル41を鉛直方向に上下させてギャップG1を調整する。ギャップ調整部8は、図7に示すように、ステージ10に固定されたベース81と、ベース81に対して鉛直方向に移動可能なスライダー82と、を有する。そして、スライダー82にノズル41が固定されている。スライダー82は、手動で移動させてもよいし、モーター等の動力を用いて移動させてもよい。ギャップG1を調整することで、製氷面21に供給するブラインBの量を調整でき、製氷面21に形成される氷9の厚さを制御することができる。そのため、所望の厚さのフレーク氷91を製造することができる。
Further, the ice making device 1 has a gap adjusting unit 8 for adjusting the gap G1 between the nozzle 41 and the ice making surface 21. The gap adjusting unit 8 adjusts the gap G1 by moving the nozzle 41 up and down in the vertical direction. As shown in FIG. 7, the gap adjusting unit 8 has a base 81 fixed to the stage 10 and a slider 82 that can move in the vertical direction with respect to the base 81. The nozzle 41 is fixed to the slider 82. The slider 82 may be moved manually or may be moved by using power such as a motor. By adjusting the gap G1, the amount of brine B supplied to the ice making surface 21 can be adjusted, and the thickness of the ice 9 formed on the ice making surface 21 can be controlled. Therefore, flake ice 91 having a desired thickness can be produced.
以上のように、製氷装置1は、平坦面で構成された製氷面21を有する製氷プレート2と、製氷面21を冷却する冷却部3と、製氷面21にブラインBを供給するブライン供給部4と、製氷面21に供給されたブラインBが冷却されてなる氷9を削り取る削取部5と、削取部5よび製氷プレート2を製氷面21と平行な方向であるX軸方向に相対的に移動させる駆動部6と、を有する。このような製氷装置1によれば、製氷面21が平坦面であるため、前述した従来技術のような円筒状のものと比べて、製氷プレート2の製造が容易となる。また、削取部5と製氷面21とのギャップの管理も容易となり、製氷面21の全域において、削取部5を均等に接触させることが容易となる。そのため、厚さの均一なフレーク氷91を製造することができ、かつ、装置の製造コストを削減することのできる製氷装置1となる。
As described above, the ice making device 1 includes an ice making plate 2 having an ice making surface 21 composed of a flat surface, a cooling unit 3 for cooling the ice making surface 21, and a brine supply unit 4 for supplying brine B to the ice making surface 21. The cutting section 5 that scrapes the ice 9 formed by cooling the brine B supplied to the ice making surface 21 and the cutting section 5 and the ice making plate 2 are relative to the X-axis direction, which is a direction parallel to the ice making surface 21. It has a drive unit 6 and a drive unit 6 for moving to. According to such an ice making device 1, since the ice making surface 21 is a flat surface, the ice making plate 2 can be easily manufactured as compared with the cylindrical one as in the above-mentioned conventional technique. Further, it becomes easy to manage the gap between the cutting portion 5 and the ice making surface 21, and it becomes easy to evenly contact the cutting portion 5 over the entire area of the ice making surface 21. Therefore, the ice making device 1 can manufacture flake ice 91 having a uniform thickness and can reduce the manufacturing cost of the device.
また、製氷面21を平坦面とすることにより、製氷面21の温度が管理し易くなり、冷却部3の能力を無駄なく使うことができる。また、製氷面21の温度管理を精度よく行うことができ、氷9の温度管理も容易となる。
Further, by making the ice making surface 21 a flat surface, the temperature of the ice making surface 21 can be easily controlled, and the capacity of the cooling unit 3 can be used without waste. In addition, the temperature of the ice making surface 21 can be controlled accurately, and the temperature of the ice 9 can be easily controlled.
<第2実施形態>
図8に示すように、本実施形態に係る製氷装置1では、ブライン供給部4が2つのノズル41A、41Bを有する。なお、ノズル41A、41Bは、それぞれ、前述した第1実施形態のノズル41と同様の構成である。また、ノズル41A、41Bは、ブレード51を間に挟んで配置されており、ブレード51のX軸方向+側にノズル41Aが位置し、X軸方向-側にノズル41Bが位置している。 <Second Embodiment>
As shown in FIG. 8, in theice making apparatus 1 according to the present embodiment, the brine supply unit 4 has two nozzles 41A and 41B. The nozzles 41A and 41B have the same configuration as the nozzle 41 of the first embodiment described above, respectively. Further, the nozzles 41A and 41B are arranged so as to sandwich the blade 51 in between, the nozzle 41A is located on the X-axis direction + side of the blade 51, and the nozzle 41B is located on the X-axis direction − side.
図8に示すように、本実施形態に係る製氷装置1では、ブライン供給部4が2つのノズル41A、41Bを有する。なお、ノズル41A、41Bは、それぞれ、前述した第1実施形態のノズル41と同様の構成である。また、ノズル41A、41Bは、ブレード51を間に挟んで配置されており、ブレード51のX軸方向+側にノズル41Aが位置し、X軸方向-側にノズル41Bが位置している。 <Second Embodiment>
As shown in FIG. 8, in the
また、駆動部6が有するガイド61は、オーバル状ではなく、直線状に延びている。そして、図9および図10に示すように、ステージ10をX軸方向+側に移動させる往路では、移動方向前方側に位置するノズル41AからブラインBを流出させてフレーク氷91を製造する。反対に、ステージ10をX軸方向-側に移動させる復路では、移動方向前方側に位置するノズル41BからブラインBを流出させてフレーク氷91を製造する。これにより、往路および復路の両方でフレーク氷91を製造することができるため、フレーク氷91の生産性が向上する。
Further, the guide 61 included in the drive unit 6 extends linearly instead of in an oval shape. Then, as shown in FIGS. 9 and 10, in the outward route for moving the stage 10 to the + side in the X-axis direction, the brine B is discharged from the nozzle 41A located on the front side in the moving direction to manufacture the flake ice 91. On the contrary, in the return route in which the stage 10 is moved in the X-axis direction − side, the brine B is discharged from the nozzle 41B located on the front side in the moving direction to manufacture the flake ice 91. As a result, the flake ice 91 can be produced on both the outward route and the return route, so that the productivity of the flake ice 91 is improved.
<第3実施形態>
図11に示すように、本実施形態に係る製氷装置1は、2つの製氷プレート2A、2Bを有する。なお、製氷プレート2A、2Bは、それぞれ、前述した第1実施形態の製氷プレート2と同様の構成である。 <Third Embodiment>
As shown in FIG. 11, theice making device 1 according to the present embodiment has two ice making plates 2A and 2B. The ice-making plates 2A and 2B have the same configurations as the ice-making plate 2 of the first embodiment described above, respectively.
図11に示すように、本実施形態に係る製氷装置1は、2つの製氷プレート2A、2Bを有する。なお、製氷プレート2A、2Bは、それぞれ、前述した第1実施形態の製氷プレート2と同様の構成である。 <Third Embodiment>
As shown in FIG. 11, the
製氷プレート2A、2Bは、それぞれ、製氷面21が鉛直面となるように立てて配置され、互いの製氷面21が向かい合うように平行に並べられている。また、これら製氷プレート2A、2Bの間には、製氷プレート2Aの製氷面21にブラインBを供給するノズル41Aと、ノズル41Aの鉛直方向上側に位置し、製氷プレート2Aに形成された氷9を削り取るブレード51Aと、製氷プレート2Bの製氷面21にブラインBを供給するノズル41Bと、ノズル41Bの鉛直方向上側に位置し、製氷プレート2Bに形成された氷9を削り取るブレード51Bと、が設けられている。そして、これらノズル41A、41Bおよびブレード51A、51Bは、それぞれ、ステージ10に固定されている。
The ice making plates 2A and 2B are arranged upright so that the ice making surfaces 21 face each other vertically, and are arranged in parallel so that the ice making surfaces 21 face each other. Further, between the ice making plates 2A and 2B, a nozzle 41A for supplying the brine B to the ice making surface 21 of the ice making plate 2A and an ice 9 located on the upper side of the nozzle 41A in the vertical direction and formed on the ice making plate 2A are placed. A blade 51A for scraping, a nozzle 41B for supplying brine B to the ice making surface 21 of the ice making plate 2B, and a blade 51B for scraping the ice 9 formed on the ice making plate 2B located on the upper side of the nozzle 41B in the vertical direction are provided. ing. The nozzles 41A and 41B and the blades 51A and 51B are fixed to the stage 10, respectively.
ステージ10は、鉛直方向(Z軸方向)に移動可能である。ステージ10をZ軸方向-側に移動させる際に、ノズル41Aから製氷プレート2Aの製氷面21にブラインBを流出させつつ、当該製氷面21に形成された氷9をブレード51Aで削り取ると共に、ノズル41Bから製氷プレート2Bの製氷面21にブラインBを流出させつつ、当該製氷面21に形成された氷9をブレード51Bで削り取ることでフレーク氷91を製造することができる。このような構成によれば、一度に2枚の製氷プレート2A、2Bでフレーク氷91を製造することができるため、フレーク氷91の生産性が向上する。また、ノズル41A、41Bの鉛直方向上側にブレード51A、51Bが位置しているため、削り取ったフレーク氷91がブレード51A、51Bに堆積することなく容器71に回収される。
The stage 10 can move in the vertical direction (Z-axis direction). When moving the stage 10 in the Z-axis direction-side, while flowing out the brine B from the nozzle 41A to the ice making surface 21 of the ice making plate 2A, the ice 9 formed on the ice making surface 21 is scraped off by the blade 51A and the nozzle. The flake ice 91 can be manufactured by scraping the ice 9 formed on the ice making surface 21 with the blade 51B while flowing the brine B from 41B to the ice making surface 21 of the ice making plate 2B. According to such a configuration, the flake ice 91 can be produced by two ice making plates 2A and 2B at a time, so that the productivity of the flake ice 91 is improved. Further, since the blades 51A and 51B are located above the nozzles 41A and 41B in the vertical direction, the scraped flake ice 91 is collected in the container 71 without accumulating on the blades 51A and 51B.
<第4実施形態>
図12および図13に示すように、本実施形態に係る製氷装置1では、製氷プレート2の上面24に複数の凹条25が形成されており、この凹条25に蛇行した冷却管26が設けられている。そして、冷却管26に冷媒Cを循環させることで、製氷面21を冷却することができる。また、冷却管26は、熱伝達部材27で覆われている。これにより、効率的に製氷プレート2との間で熱交換を行うことができる。熱伝達部材27としては、特に限定されないが、例えば、各種金属材料、金属フィラーが混入された樹脂材料等を用いることができる。 <Fourth Embodiment>

Has been done. Then, the ice making surface 21 can be cooled by circulating the refrigerant C in the cooling pipe 26. Further, the cooling pipe 26 is covered with a heat transfer member 27. As a result, heat exchange with the ice making plate 2 can be efficiently performed. The heat transfer member 27 is not particularly limited, but for example, various metal materials, resin materials mixed with metal fillers, and the like can be used.

以上、本発明の製氷装置について図示の実施形態に基づいて説明したが、本発明はこれに限定されるものではない。例えば、製氷装置の各部の構成は、同様の機能を発揮する任意の構成のものに置換することができ、また、任意の構成を付加することもできる。また、前述した実施形態を適宜組み合わせてもよい。
Although the ice making apparatus of the present invention has been described above based on the illustrated embodiment, the present invention is not limited to this. For example, the configuration of each part of the ice making device can be replaced with an arbitrary configuration that exhibits the same function, or an arbitrary configuration can be added. In addition, the above-described embodiments may be combined as appropriate.
以上のように、本発明に係る製氷装置1は、平坦面で構成された製氷面21を有する製氷プレート2と、製氷面21を冷却する冷却部3と、製氷面21にブラインBを供給するブライン供給部4と、製氷面21に供給されたブラインBが冷却されてなる氷9を削り取る削取部5と、削取部5よび製氷プレート2を製氷面21と平行な方向であるX軸方向に相対的に移動させる駆動部6と、を有する。このような製氷装置1によれば、製氷面21が平坦面であるため、前述した従来技術のような円筒状のものと比べて、製氷プレート2の製造が容易となる。また、削取部5と製氷面21とのギャップの管理も容易となり、製氷面21の全域において、削取部5を均等に接触させることが容易となる。そのため、厚さの均一なフレーク氷91を製造することができ、かつ、装置の製造コストを削減することのできる製氷装置1となる。したがって、その産業上の利用可能性は大きい。
As described above, the ice making device 1 according to the present invention supplies the ice making plate 2 having the ice making surface 21 formed of a flat surface, the cooling unit 3 for cooling the ice making surface 21, and the brine B to the ice making surface 21. The X-axis of the brine supply section 4, the scraping section 5 from which the brine B supplied to the ice making surface 21 is cooled to scrape the ice 9, and the scraping section 5 and the ice making plate 2 in a direction parallel to the ice making surface 21. It has a drive unit 6 that moves relative to the direction. According to such an ice making device 1, since the ice making surface 21 is a flat surface, the ice making plate 2 can be easily manufactured as compared with the cylindrical one as in the above-mentioned conventional technique. Further, it becomes easy to manage the gap between the cutting portion 5 and the ice making surface 21, and it becomes easy to evenly contact the cutting portion 5 over the entire area of the ice making surface 21. Therefore, the ice making device 1 can manufacture flake ice 91 having a uniform thickness and can reduce the manufacturing cost of the device. Therefore, its industrial applicability is great.
