INDUSTRIAL APPLICATION FIELD The present invention relates to an ice making apparatus for producing ice having any hardness and shape, from shearbet ice, flake ice, to block ice, using supercooled water. PRIOR TECHNOLOGY In general, ice blocks are produced by mechanically crushing blocks of ice made in an ice cube tray, etc.; This requires a crushing operation, which makes the process complicated and time-consuming. (b) Crushed ice made by crushing large blocks has a high hardness, so when used for cold storage, there is a risk of damaging the items to be kept cold. (c) It is difficult to produce ice with uniform particle size through crushing operations. There are other problems. On the other hand, an attempt has been made to cool water to below 0° C. to produce supercooled water and use this to make ice. The most common conventional method for producing supercooled water is the standing method. This is a method of slowly cooling the water to a supercooled state while it remains stationary, but (a) the cooling efficiency is low because heat is transferred to the water only by natural convection. (b) Because the supercooled state is unstable, even the slightest stimulus such as vibration will break the supercooled state and cause it to freeze. (c) Once frozen, ice and water coexist, and even if cooling continues, ice will only grow from the heat transfer surface and the supercooling temperature will no longer be reached. There are other problems. JP-A-54-102648 discloses that a dilute aqueous solution to which a freezing point depressant has been added is filled into an ice-making container equipped with a cooling device and a stirrer, cooled to a supercooled state while stirring, and then the stirring is interrupted. A method has been proposed in which a large number of flakes of ice are generated inside an aqueous solution by using a freezing point depressant, but this method combines the action of a freezing point depressant and the stirring action to reach a supercooled state throughout the container. There is a drawback that adverse effects occur due to the contamination of depressants. Furthermore, since the area around the stirring blades freezes, there is a drawback that operation becomes intermittent and efficiency decreases. Problems to be Solved by the Invention An object of the present invention is to provide an ice making device that can continuously and inexpensively produce ice having any hardness and shape, from shearbet ice to flake ice to block ice. It is in. Means for Solving the Problems and Their Effects The above object of the present invention is to provide a supercooled water production heat exchanger comprising a first structure through which a refrigerant or brine flows and a second structure through which water flows; An ice tank, a discharge pipe that discharges supercooled water at the upper part of the ice storage tank, an opening with a nozzle and an opening without a nozzle provided in this discharge pipe, and a space between the discharge pipe and the opening with a nozzle and the opening without a nozzle. This is achieved by an ice-making device that includes a switching valve that opens and closes, a water pump, a refrigerant or brine circulation circuit, and a control unit that adjusts the temperature, flow rate, or pressure of supercooled water. With this configuration, the water supplied by the water pump is cooled to below 0°C in the heat exchanger to become supercooled water, which is transferred to the upper part of the ice storage tank and discharged through an opening with a nozzle or an opening without a nozzle. However, the supercooled water freezes due to the impact of the fall, and then begins to form ice. The state of this ice varies depending on the temperature of the supercooled water, the presence or absence of a nozzle, the particle size of the spray, etc., and the hardness and shape of the ice change. Therefore, by opening and closing the passages to the opening with a nozzle and the opening without a nozzle using a switching valve, the presence or absence of a nozzle is switched, and the temperature of the supercooled water is changed by the function of the control section, and the flow rate or pressure is changed. By changing the atomized particle size, ice of arbitrary hardness and shape can be obtained. The control section includes a temperature sensor that detects the temperature of supercooled water, and a control unit that controls the operations of the refrigerator, water pump, flow rate adjustment valve, pressure control valve, etc. Other characteristics and advantages of the invention will become apparent from the following description with reference to the embodiments of the accompanying drawings. Embodiment FIG. 1 shows an ice making apparatus according to a preferred embodiment of the present invention, and this apparatus as a whole is composed of a supercooled water production section, an ice storage section, and a control section. The supercooled water production section includes a double pipe heat exchanger 13 consisting of an outer coil 11 through which brine such as ethylene glycol cooled by the refrigerator 10 flows and an inner coil 12 through which water flows, a brine circulation pump 14, and a control valve. (Expansion valve) 15 is included. The ice storage section includes an ice storage tank 20 having a heat insulating wall, a supercooled water discharge pipe 21 that transfers supercooled water from the outlet of the heat exchanger 13 to the top of the ice storage tank and releases it, and near the bottom of the ice storage tank. It includes a return pipe 22 that transfers water from the water to the inlet of the heat exchanger, and a water circulation pump 23 and a control valve (flow rate adjustment valve or pressure control valve) 24 located in the middle of the return pipe 22. The part of the discharge pipe 21 inside the ice storage tank is connected to the branch pipe 3.
The branch pipe 31 is provided with an opening 33 with a nozzle and an electromagnetic switching valve 35.
2 is provided with a nozzleless opening 34 and an electromagnetic switching valve 36. Inside the ice storage tank 20 is a perforated plate 40
An ice removal door 41 is provided on the side of the ice storage section, and a return pipe 22 of the cooling section is partitioned into an upper and lower section.
A strainer 42 is attached to the connecting portion. The control unit includes a temperature sensor 38 installed in the middle of the discharge pipe 21 for detecting the temperature of supercooled water.
, cooler 10, pumps 14 and 23, control valve 1

It works by rotating the fluid in a spiral and atomizing it, expanding the spread of the spray. Branch pipe 32
The nozzle-less opening 34 at the tip has a structure in which the nozzle 50 of FIG. 2 is removed. The nozzle 50 is preferably made of resin or metal coated with a resin to prevent supercooled water from freezing due to fluid turbulence inside the nozzle. Based on this configuration, the ice making apparatus of the present invention is operated as follows. First, the refrigerator 10 is operated to lower the brine temperature to -6℃, and the heat exchanger 1 is
Send it within 3. On the other hand, cold water drawn from the bottom of the ice storage tank 20 is cooled with brine in a heat exchanger, turned into supercooled water below 0°C, and transferred to the top of the ice storage tank through a branch pipe to an opening 33 with a nozzle. Alternatively, the ice is ejected and dropped from the nozzleless opening 34 into the ice storage tank. The supercooled water freezes due to the impact of the fall, but
The state changes, for example, as follows depending on the temperature of the supercooled water, the presence or absence of a nozzle, and the spray particle size.

It changes into a block shape. Therefore, if the frozen ice in the ice storage tank does not have the desired hardness and shape, the control unit 39 can be operated to start or stop the refrigerator or pump, or change the control valve. All you have to do is The spray particle size when supercooled water is ejected varies depending on the shape, pressure, and flow rate of the spray nozzle, but
An example of this is shown in FIG. In the graph in Figure 4, the spray nozzle is a straight circular full-cone spray type with a pipe diameter of 1/4 inch and a blowout hole diameter of 2.6 mm, and SR-2410 resin manufactured by Toray Silicone Co., Ltd. is layered twice on the wetted part. The material used was one that was coated, dried (cured) at room temperature, and then coated with silicone. From the characteristic curve in the figure, the gauge pressure
The spray particle size is 5 mm in diameter when the flow rate is 1.5/min at 0.1Kg/ cm2 , and the flow rate is 2.2/min at a gauge pressure of 03Kg/ cm2.
It can be seen that the spray particle size is 1 mm in diameter when . As a modification of the present invention, the return pipe 22 in FIG. 1 is omitted and water is supplied from a water source other than the ice storage tank 20,
It is also possible to use a transient type device that is not an environmental type. The ice making apparatus according to the present invention is most suitable for the following applications. (a) Shaved ice making machine By changing the hardness, shape, and particle size of the ice, you can enjoy the texture that suits your personal taste.

Effects of the Invention As described above in detail, the ice making apparatus of the present invention provides the following advantages. (1) Ice of any hardness and shape can be obtained from shearbet ice/flake ice to block ice. (2) Since there is no need to crush large chunks, the process is continuous and work efficiency is improved. (3) The range of applications for objects to be refrigerated will expand, and the demand for ice will increase. (4) The cost of ice will decrease due to process automation.
