Description

  TECHNICAL FIELD The present invention relates to a production method for producing drinking water and ice containing a functional component using water containing the functional component as ice making water, and a production apparatus for carrying out the production method.

  In recent years, water containing a functional component such as electrolyzed water containing silver ions or silver colloid as a silver component has attracted attention because the functional component contained therein functions usefully. For example, a method for generating water containing a silver component such as silver ions or silver colloid as a functional component includes a method of generating water by diaphragm electrolysis or diaphragm electrolysis using a silver electrode as an anode electrode, silver There is a method in which powder or the like is directly added to water and dissolved with sufficient stirring. However, in these methods, the content of the silver component is naturally limited. For this reason, the production | generation of the water which contains a silver component in large quantities is requested | required.

  On the other hand, a normal method for generating ice is to use general water such as natural water or tap water as ice making water, and a method of making the ice making water with various types of ice making apparatuses is employed. In the ice making method, since there are almost no impurities in the ice making water, transparent ice made of clear water with almost no impurities is produced. In addition, when making ice using water that contains slightly impurities, ice is made using the freezing point effect of water, so that most of the impurities contained in the ice-making water are removed during freezing. As a result, the ice is frozen, and the resulting ice is almost free of impurities, and the ice-making water remaining in an unfrozen state contains a large amount of impurities in a concentrated state.

As for ice making water, a patent application has been filed under the name of “electrolyzed water and electrolytic ice supply device” for an ice production method and production apparatus using ice water as a unique water different from general water (Patent Document 1). See). The electrolytic ice supply device uses electrolytically generated alkaline water as ice-making water, and is intended to produce ice that freezes electrolytically generated alkaline water. However, since electrolytically generated alkaline water does not contain functional components corresponding to impurities, the supply device does not produce ice containing functional components, and has not yet been produced at the end of ice making. The ice-making water remaining in the frozen state does not contain functional components corresponding to impurities.

In addition, the ice frozen in the ice making section is collected after the ice making is completed.

  In each production method according to the present invention, ice making water containing a silver component as a functional component can be employed as the ice making water. The ice making water can be generated by electrolysis using water as the anode electrode. Further, the ice making water can be produced by diaphragm electrolysis or non-diaphragm electrolysis using electrolyzed water produced by electrolysis using a silver electrode as an anode electrode as water to be electrolyzed.

  The manufacturing apparatus according to the present invention is a manufacturing apparatus for carrying out each manufacturing method according to the present invention. The manufacturing apparatus according to the present invention includes a preparation mechanism for preparing the ice-making water and an ice-making machine that freezes the ice-making water. Basically, the ice making mechanism includes an ice making part having an ice making surface for freezing supplied ice making water, and a residual part for leaving uniced ice making water on the ice making surface.

The ice making water remaining after freezing is collected as drinking water after the ice making is completed, and the ice frozen in the ice making unit is collected after the ice making is completed.

  In each manufacturing apparatus according to the present invention, the preparation mechanism is generated by an electrolyzed water generation mechanism having a diaphragm electrolyzer having a silver electrode as an anode electrode, or by the same electrolyzer with the diaphragm electrolyzer. In addition, an electrolyzed water generation mechanism having an electrolytic cell for electrolyzing the electrolyzed water with diaphragm or non-diaphragm electrolysis can be employed.

  According to the manufacturing method according to the present invention, ice making water is made by using the freezing point depression of ice making water, so that at the time of freezing of ice making water, the ice making water is frozen in a state where most of the functional components contained therein are removed. Thus, ice with a low content of functional components is produced. On the other hand, functional components removed by freezing point depression during freezing remain in unfrozen ice-making water, and ice-making water remaining in an unfrozen state after completion of ice-making has a larger amount of functional components than in the preparation of ice-making water. It will contain.

  For this reason, if the ice making water remaining after freezing is collected after the ice making is completed, the drinking water containing the functional component in an amount larger than the amount of the functional component contained in the ice making water can be collected.

Become.

  Water and ice containing a large amount of functional components are extremely useful as functional agents, but ice containing functional components is due to the large freezing point depression of ice-making water containing functional components. It becomes hard and thick ice and is also useful as a cooling agent when transporting fresh food products. Further, when ice-making water containing a silver component as a functional component is employed, the ice is extremely useful as the above-described coolant because it has a bactericidal ability.

  In this case, since the ice making water itself has a sterilizing ability, it is effective for sterilization of the aqueous circuit of the manufacturing apparatus to be used. If ice making water containing a silver component is used, from the aspect of hygiene management of the manufacturing apparatus. Is also effective.

  TECHNICAL FIELD The present invention relates to a production method for producing drinking water and ice containing a functional component using water containing the functional component as ice making water, and a production apparatus for carrying out the production method. FIG. 1 shows a manufacturing apparatus according to a first embodiment for carrying out the manufacturing method according to the present invention. The manufacturing apparatus includes an ice making mechanism 10 that manufactures ice and a preparation mechanism 20 that prepares ice-making water and supplies it to the ice making mechanism 10. In the manufacturing apparatus, the ice-making water prepared by the preparation mechanism 20 is supplied to the ice-making mechanism 10 and frozen in the ice-making unit of the ice-making mechanism 10, and the ice-making water remaining in an uniced state at the end of ice making is used as drinking water. The ice collected and frozen in the ice making section is continuously collected during ice making.

  The ice making mechanism 10 is a drum rotation type ice making mechanism and includes an ice making drum 12 disposed in a storage tank 11 formed in a housing 10a and a cutter 13 functioning as a peeling blade. The ice making drum 12 has a cylindrical shape whose both ends are closed in a sealed state, and a cooling mechanism for cooling the ice making surface 12a which is the outer peripheral surface of the ice making drum 12 is housed therein. The ice making drum 12 is arranged in a horizontal state with its axis centered horizontally, and is supported rotatably about the axis. The ice making drum 12 is rotationally driven in the storage tank 11 by a drive mechanism (not shown) during the ice making operation.

  During the ice making operation, a predetermined amount of ice making water W is stored in the storage tank 11, and in this state, approximately 3/4 of the ice making drum 12 is submerged in the ice making water W stored in the storage tank 11. It becomes a state. In this arrangement state, the ice making drum 12 rotates in the direction of an arrow, for example. However, the cutter 13 is arranged at a portion immediately before submersion in the rotation direction in the portion where the ice making surface 12a of the ice making drum 12 is exposed from the ice making water W. It is installed. The tip edge of the cutter 13 is positioned facing the ice making surface 12a while maintaining a minute interval. In addition, the space | interval of the front-end | tip blade of the cutter 13 and the ice making surface 12a is set to the space | interval smaller than the thickness of the ice which freezes on the ice making surface 12a.

  In the ice making mechanism 10, during the ice making operation, a predetermined amount of ice making water W prepared by the preparation mechanism 20 described later is received in the storage tank 11, and the ice making surface of the ice making drum 12 as shown in FIG. Substantially 3/4 of 12a is submerged, and the ice making drum 12 is rotated in the direction of the arrow. The ice making mechanism 10 includes a water level sensor 14 that detects the water level of the ice making water W stored in the storage tank 11 while the ice making water W in the storage tank 11 is gradually consumed and reduced during the ice making operation. Thus, when the water level of the ice making water W in the storage tank 11 is reduced by a predetermined height, the preparation operation of the preparation mechanism 20 is restarted and a predetermined amount of ice making water W is supplied to the storage tank 11. ing. Thereby, the ice making water consumed during the ice making operation is appropriately supplemented.

  In the ice making operation in the ice making mechanism 10, ice is gradually formed on the ice making surface 12 a of the ice making drum 12 below the surface of the ice making water W accommodated in the storage tank 11 to form a layered ice having a predetermined thickness. And is exposed to the surface of the ice-making water W and becomes supercooled, resulting in dried layered ice containing almost no water. The layered ice is sequentially peeled off from the ice making surface 12a by the cutter 13 immediately before the ice making surface 12a of the ice making drum 12 is submerged again to form a large amount of ice pieces, and the chute formed in the housing 10a. 15 is stored in the ice storage.

  On the other hand, the preparation mechanism 20 for preparing ice-making water is an electrolysis-type preparation mechanism including two electrolytic cells 20a and 20b, and uses tap water as raw water. The tap water is supplied to the first electrolyzer 20a through a water softener and a filter.

  The first electrolytic cell 20a is a non-diaphragm electrolytic cell, and a first electrode 22a, which is a silver electrode, and a second electrode 22b, which is a stainless steel electrode, are disposed inside the cell body 21 so as to face each other. Has been. In the first electrolytic cell 20a, the first electrode 22a, which is a silver electrode, is set as an anode side electrode, and the second electrode 22b, which is a stainless steel electrode, is set as a cathode side electrode. In the first electrolyzer 20a, electrolyzed water containing silver ions is generated in the electrolysis chamber R by electrolysis. The generated silver ion-containing electrolytically generated water is supplied to the second electrolytic bath 20b as electrolyzed water. The second electrolytic cell 20b is employed by appropriately selecting a diaphragm electrolytic cell and a non-diaphragm electrolytic cell.

  As shown in FIG. 2, the diaphragm electrolytic cell 20b1, which is the second electrolytic cell 20b, includes a tank body 23, an ion-permeable diaphragm 24 that partitions the tank body 23 into a pair of electrolytic chambers, and each electrolytic cell. Each of the chambers is provided with a pair of platinum electrodes 25a and 25b that form the electrolysis chambers in an anode electrolysis chamber R1 and a cathode electrolysis chamber R2. In the diaphragm electrolyzer 20b1, the silver ion-containing electrolyzed water produced in the first electrolyzer 20a is supplied as electrolyzed water to the electrolysis chambers R1 and R2 through the supply pipes 26a and 26b. The

  Electrolytically generated acidic water is generated in the anode-side electrolysis chamber R1 supplied with silver ion-containing electrolytically generated water, and electrolytically generated alkaline water is generated in the cathode-side electrolytic chamber R2 supplied with silverion-containing electrolytically generated water. Is done. The generated electrolytically generated acidic water and electrolytically generated alkaline water are selectively supplied to the storage tank 11 of the ice making mechanism 10 as ice making water containing silver components through the outflow pipes 26c and 26d.

  As shown in FIG. 3, the non-diaphragm electrolytic cell 20 b 2, which is the second electrolytic cell 20 b, includes a tank body 27 and platinum electrodes 28 a and 28 b disposed opposite to each other in the tank body 27. Yes. In addition, a branching projection 27 a is formed at the central portion of the upper wall on the downstream side in the tank body 27. In the diaphragm electrolyzer 20b2, the silver ion-containing electrolyzed water produced in the first electrolyzer 20a is supplied as electrolyzed water to the electrolysis chamber R through the supply pipes 29a and 29b. The supplied electrolyzed water containing silver ions is electrolyzed again in the electrolysis chamber R to become electrolyzed water, but electrolyzed acidic water is distributed in the vicinity of the anode side electrode 28a, and in the vicinity of the cathode side electrode 28b. Electrolytically generated alkaline water is distributed. The electrolytically generated acidic water in the electrolysis chamber R is extracted from the outflow pipe 29c opened near the anode side electrode 28a, and is selectively supplied to the storage tank 11 of the ice making mechanism 10 as ice making water containing a silver component. The Further, the electrolytically generated alkaline water in the electrolysis chamber R is extracted from the outflow pipe 29d opened near the cathode side electrode 28b, and is selectively supplied to the storage tank 11 of the ice making mechanism 10 as ice making water containing a silver component. Supplied.

  If the manufacturing apparatus having such a configuration is used, the first manufacturing method according to the present invention can be carried out using the electrolytically generated water containing silver components as water for ice making. In the ice making operation by the manufacturing apparatus, the preparation mechanism 20 is first operated to start the preparation operation of the ice making water W, and the tap water is supplied as electrolyzed water into the electrolysis chamber R of the first electrolyzer 20a. . The tap water supplied to the electrolysis chamber R is electrolessly electrolyzed in the electrolysis chamber R, and electrolyzed water containing a silver component is generated. The electrolyzed water is supplied to the electrolysis chambers R1, R2 of the diaphragm electrolyzer 20b1 or the electrolysis chamber R of the non-diaphragm electrolyzer 20b2, and is electrolyzed again in each of the electrolysis chambers R1, R2 or the electrolysis chamber R.

  The electrolytically generated acidic water and the electrolytically generated alkaline water generated in the electrolytic chambers R1 and R2 of the diaphragm electrolyzer 20b1 are selectively supplied into the storage tank 11 of the ice making mechanism 10 through the outflow pipes 26c and 26d. Is done. As for the electrolytically generated water generated in the electrolysis chamber R of the diaphragm electrolyzer 20b2, electrolytically generated acidic water and electrolytically generated alkaline water are selectively stored in the ice making mechanism 10 through the outflow pipes 29c and 29d. It is supplied into the tank 11. In the manufacturing apparatus, when the water level sensor 14 detects that a predetermined amount of ice-making water W has been stored in the storage tank 11, a detection signal is output to a control device (not shown). The control device stops the ice making operation by the ice making mechanism 10 based on the detection signal from the water level sensor 14 and stops the supply of the ice making water W into the storage tank 11. In the ice making operation, the ice making drum 12 cooled to a predetermined temperature is rotationally driven at a predetermined low speed while being partially submerged in the ice making water W accommodated in the storage tank 11.

  In the ice making operation, ice is gradually generated on the ice making surface 12a of the ice making drum 12 below the surface of the ice making water W accommodated in the storage tank 11, and grows into layered ice, and then grows to a predetermined thickness. The ice is exposed on the surface of the ice making water W and becomes supercooled, resulting in dried layered ice containing almost no water. The layered ice is sequentially peeled off from the ice making surface 12a by the cutter 13 immediately before the ice making surface 12a of the ice making drum 12 is submerged again to form a large amount of ice pieces, and the chute formed in the housing 10a. 15 is stored in an ice storage (not shown).

  In the ice making operation, the ice making water W in the storage tank 11 is consumed and reduced over time, but the water level sensor 14 monitors the consumption of the ice making water W, and the water level of the ice making water W decreases by a predetermined height. When this occurs, this is detected and output as a detection signal to the control device. Based on the detection signal, the control device restarts the ice making water preparation operation by the preparation mechanism 20 and replenishes the storage tank 11 with a predetermined amount of ice making water W.

  In the preparation operation of the preparation mechanism 20 constituting the manufacturing apparatus according to the present invention, electrolyzed water having a silver ion concentration of 300 ppb and a pH of 7.43 (23.6 ° C.) can be obtained. When the sterilization experiment was conducted using the electrolytically generated water, the results shown in Table 1 were obtained.

  In addition, by the ice making operation of the ice making mechanism 10 constituting the manufacturing apparatus according to the present invention, electrolyzed water having a different silver ion concentration of 300 ppb and different pH is prepared, and these electrolyzed water is used as ice making water so that the silver ion concentration is constant An ice making operation using electrolytically generated water with different pH was performed, and an experiment was performed in which the silver component contained in each of the generated ice was calculated as the silver ion concentration. The obtained results are shown in the graph of FIG. However, in this experiment, each produced ice was once thawed, the amount of silver ions was measured, and the silver component residual rate as the vertical axis of the graph was calculated. The silver component residual ratio means a ratio in which the amount of the silver component contained in the water for ice making as raw water and the amount of the silver component contained in the aqueous solution obtained by thawing ice pieces are compared.

  Thus, in the ice making operation by the ice making mechanism 10, ice containing most of the silver component contained in the ice making water, in other words, ice containing the silver component can be produced. Further, in the ice making water remaining in the storage tank 11 in an unfrozen state, the silver component separated from the ice is transferred at the time of freezing, and at the end of the ice making, it contains more silver component than the raw water. . Therefore, if the ice-making water remaining in an unfrozen state is collected in the storage tank 11 after the ice making is completed, the drinking water in which the silver component is concentrated can be obtained. Since the drinking water contains a silver component, it has an immunostimulatory ability to improve immunity and can be provided as an immunostimulator.

  Further, if the ice making method is adopted, since the freezing point depression is greatly reduced because the silver component contained in the ice making water is contained, the layered ice generated on the ice making surface 12a of the ice making drum 12 has impurities. Compared with the case where tap water or the like that is not substantially contained is used as ice-making water, the thickness is considerably thicker. For this reason, the ice pieces obtained by stripping off the layered ice are considerably large and hard ice blocks.

  Since the silver component is a component suitable for food and drink, the ice piece can be effectively used as a frozen or cooled food or drink. Moreover, since a silver component has bactericidal ability, a preservation | save function, etc., it can utilize effectively also as a cooling agent when conveying various foodstuffs etc. in a cooling environment. In such a use mode, it is preferable that the ice piece is a hard and large ice block. When the ice piece is a hard and large ice block, there is little damage such as crushing of the ice piece during handling, and the ice piece. This has the advantage that the form retention time is long, and is easy to use as a coolant.

  For example, since water containing a silver component has an immunostimulatory ability to improve immunity, the ice can be provided as a cooled immunostimulant that is easy to drink. In addition, since water containing silver component has high bactericidal ability and preservation function due to this, it is extremely effective as a cooling agent when transporting fresh fish or fresh vegetables in a cooling environment, and it is a hard and large ice block. Is difficult to thaw and has the function of maintaining the cooling ability for a long time.

  If the ice making method is adopted, the ice making water containing the silver component has a sterilizing ability. Accordingly, the ice making water preparation mechanism 20, the ice making mechanism 10 water system conduit, and the ice transport path after freezing. This is extremely advantageous in terms of hygiene management of the manufacturing apparatus.

  In the manufacturing apparatus according to the first embodiment of the present invention, an example in which the drum rotation type ice making mechanism 10 is adopted as the ice making mechanism is shown. However, in this embodiment, the drum type ice making mechanism is used. Instead of 10, an auger type ice making mechanism can be adopted.

  The auger type ice making mechanism includes a standing cylindrical ice making drum and an auger disposed concentrically inside the ice making drum and facing the ice making surface which is the inner peripheral surface of the ice making drum. The ice making water contained in the ice making drum is frozen on the ice making surface to generate layered ice, and the generated layered ice is driven off by rotating the auger and sequentially peeled off by the tip blade. It is. Therefore, by adopting the auger type ice making mechanism, it is possible to configure the manufacturing apparatus according to the first embodiment of the present invention, and to implement the first embodiment of the manufacturing method according to the present invention. be able to.

  In FIG. 5, the manufacturing apparatus which concerns on 2nd Embodiment which implements the manufacturing method which concerns on this invention is shown. The manufacturing apparatus includes an ice making water preparation mechanism 20 and an ice making mechanism 30. The preparation mechanism 20 is the same preparation mechanism as the preparation mechanism 20 employed in the manufacturing apparatus of the first embodiment. The ice making mechanism 30 is different from the ice making mechanism 10 employed in the manufacturing apparatus of the first embodiment in a method of supplying ice making water to the ice making unit. The ice making mechanism 10 uses a storage and supply system, while the ice making mechanism 30 uses a circulation and supply system.

  The ice making mechanism 30 is formed by arranging a plurality of ice making plates 32 in parallel in an upright state in a housing 31, and each ice making plate 32 houses a cooling mechanism therein, and during the ice making operation, The surface of the ice making surface is cooled to a temperature at which the ice making water can be frozen. A watering tank 33 is disposed above each ice making plate 32, and a watering nozzle directed to the ice making surface of each ice making plate 32 is provided in the watering tank 33. During the ice making operation, the ice making water W stored in the storage tank 34 installed outside the housing 31 is supplied to the water spray tank 33 through the supply pipe 35. The storage tank 34 is supplied with a predetermined amount of electrolyzed water containing silver component prepared by the preparation mechanism 20 as ice making water.

  In the ice making operation of the ice making mechanism 30, the ice making water W stored in the storage tank 34 is continuously supplied to the sprinkler tank 33 through the supply pipe 35. The ice making water continuously supplied to the water sprinkling tank 33 is supplied to the upper end of the ice making surface of each ice making plate 32 through each water spray nozzle, and flows down substantially evenly over the entire width of each ice making surface. A part of the ice making water is frozen while flowing down on each ice making surface, and the ice-free water in an unfrozen state falls to the bottom of the housing 31 and enters the storage tank 34 through a slat-like portion provided on the bottom. Reflux. The ice making water W in the storage tank 34 is integrated with the ice making water that has been refluxed without being frozen, and the ice making water W in this state is continuously supplied to the watering tank 33.

  Accordingly, in the ice making mechanism 30, the ice making water is supplied to each ice making plate 32 in a circulation supply system, and the ice making water W in the storage tank 34 gradually has a ratio of the ice making water W recirculating in an uniced state. Get higher. During this time, on the ice making surface of each ice making plate 32, the ice making water flowing down gradually freezes and grows into layered ice, and becomes layered ice I having a predetermined thickness at the end of ice making. Further, at the time of completion of ice making, the ice making water W remaining in the storage tank 34 is in a state where the silver component is concentrated by the high concentration silver component brought in by the ice making water that is sequentially refluxed, and contains the silver component at a high concentration. It becomes.

  At the end of the ice making operation, the ice making surface of each ice making plate 32 is heated, and the layered ice I generated on the ice making surface of each ice making plate 32 is detached from each ice making surface and falls. The layered ice indicated by the symbol I shows a state where the ice is separated from the ice making surface and is falling. The falling layered ice I is received by the receiving member 36 disposed above the bottom of the housing 31, and descends toward the crusher 37 along the bottom of the receiving member 36. The crusher 37 sequentially crushes the descending layered ice I from the tip side, and supplies it to an ice storage tank (not shown) as an ice block of a predetermined size.

  The ice block produced by the ice making operation has a silver component compared to the ice making mechanism 10 adopting the storage and supply method because the supply method to the ice making surface of each ice making plate 32 is the circulation supply method. On the contrary, the amount of the silver component of the ice making water remaining in the storage tank 34 in an unfrozen state increases. For this reason, at the end of ice making, drinking water having a high concentration of silver component can be collected from the storage tank 34.
