Description

  The present invention relates to an ice making device.

  Conventionally, in order to maintain the freshness of seafood, the seafood has been cooled with block ice. However, in recent years, salt water (brine) has been used for massive ice because seawater fish can be damaged by massive ice due to vibrations during ocean and land transportation, and the ice can become fresh water due to melting of the massive ice. The seafood is being cooled with sherbet-like or snowy ice produced by cooling the fish.

  For example, an apparatus described in Patent Document 1 is known as an apparatus for producing a sherbet-like or snow-like ice from salt water. The ice making device of Patent Document 1 has an ice accumulation / growth layer, a seawater storage layer, and a screen that can be moved up and down arranged in the ice accumulation / growth layer. The ice produced by a special ice maker is stored on the screen in the ice accumulation / growth layer. Further, the ice stored on the screen can be taken out by raising the screen.

  However, in such an ice making device, as described above, since the ice is taken out by raising the screen, it is necessary to secure a space for taking out the ice above the ice making device. Therefore, when it is installed indoors, the ceiling height is limited, and the practicality of the apparatus is lowered.

  The 1st storage part 2 is a tank for storing the ice I produced | generated from this salt water W while storing the salt water (brine) W used as the raw material of the ice I. FIG. In addition, although it does not specifically limit as the salt water W, For example, the salt water whose salt concentration is about 1.0%-5.0% can be used, and seawater can be used suitably. By using this level of salt water, ice I having a salinity of about 1% can be produced, and ice I is suitable for cold storage of seafood SF.

  Such a 1st storage part 2 comprises frame shape, and has the upper part opening 21 opened to the upper part, and the bottom part opening 22 opened to the bottom part. Further, the bottom opening 22 is closed by the separation unit 3 and the second storage unit 4 provided on the lower side of the first storage unit 2. Thereby, the salt water W can be stored in the 1st storage part 2. FIG. In addition, a seal member (not shown) is disposed between the first storage unit 2 and the separation unit 3 or between the separation unit 3 and the second storage unit 4, and thereby the first storage unit 2 and the separation unit 3. Bleeding of the salt water W from between the separation part 3 and the second storage part 4 is prevented. In addition, although it does not specifically limit as a capacity | capacitance of the 1st storage part 2, For example, it is preferable that it is about 500 liters-1000 liters. Thereby, excessive enlargement (especially height increase) of the apparatus can be prevented, and a sufficient amount of ice I can be stored in the first storage unit 2.

  The separation unit 3 positioned below the first storage unit 2 is a member for introducing substantially only the salt water W from the first storage unit 2 into the second storage unit 4. The separation unit 3 has a plate shape and includes a main body 31 having a plurality of through holes 311 penetrating in the plate thickness direction, and a filtering member 32 disposed in the through hole 311. Thereby, the structure of the isolation | separation part 3 becomes a simple thing. The filtering member 32 is not particularly limited as long as it allows passage of the salt water W and restricts the passage of ice (ice crystals) I. For example, various porous bodies such as nonwoven fabrics, woven fabrics, knitted fabrics, sponges, etc. Can be used.

  The 2nd storage part 4 located in the lower side of such a separation part 3 is a tank which stores the salt water W filtered by the separation part 3. FIG. In addition, a feed unit 5 and a discharge unit 7 are provided at the bottom of the second storage unit 4. And the salt water W in the 2nd storage part 4 can be supplied to the cooling unit 10 via the supply part 5, and the salt water in the 2nd storage part 4 is discharged | emitted outside the apparatus via the discharge part 7. be able to. The discharge portion 7 is provided with a valve (not shown) so that the salt water W can be discharged by opening the valve. Here, the ice making device 1 has the second storage unit 4, but omits the second storage unit 4. For example, the feeding unit 5 and the discharge unit 7 are directly connected to the through-hole 311 of the separation unit 3. , You may connect.

  The salt water W in the second storage unit 4 is supplied to the cooling unit 10 via the supply unit 5. The cooling unit 10 is a unit that generates ice I by cooling the salt water W supplied from the feeding unit 5. The cooling unit 10 includes an ice generator (heat exchanger) 101 that generates ice I from the salt water W, a motor 102 that drives the ice generator 101, and a refrigerator 103 that circulates the refrigerant C through the ice generator 101.

The salt water W supplied to the ice generator 101 through the supply unit 5 is gradually cooled by heat exchange with the refrigerant C supplied from the refrigerator 103, and a part of the fine ice (ice crystals) containing salt is contained. ) I. The salt water W containing the ice I is discharged from the ice generator 101 and then injected into the first storage unit 2 through the injection unit 6. Thus, by circulating the salt water W between the first storage unit 2 and the cooling unit 10, the fine ice I generated by the cooling unit 10 is gradually stored in the first storage unit 2.

  The injection unit 6 is provided through the second storage unit 4 and the separation unit 3, and injects salt water W containing ice I from the center of the bottom of the first storage unit 2. In other words, the injection part 6 injects the salt water W containing the ice I directly into the salt water W stored in the first storage part 2. Thereby, the impact at the time of injection | pouring can be relieved. Moreover, a convection can be generated in the salt water W in the 1st storage part 2, and the coupling | bonding of ice I can be suppressed. Therefore, finer ice I can be stored. In addition, arrangement | positioning of the injection | pouring part 6 is not specifically limited, For example, the salt water W may be inject | poured through the upper opening 21 provided above the 1st storage part 2. As shown in FIG.

Can be discharged to the outside of the apparatus. Thereby, water can be extracted from the ice I stored in the first storage part 2 located above, and the water of the ice I stored in the first storage part 2 can be cut. Therefore, softer ice I with less moisture can be produced. Note that the discharge unit 7 may forcibly remove the salt water W from the first reservoir using a suction means such as a suction pump, or may naturally remove the salt water W from the first reservoir. Good.

  Here, although it returns to description of the 1st storage part 2, in order to collect | recover the ice I in the 1st storage part 2, the 1st storage part 2 intersects with the isolation | separation part 3 in a substantially horizontal direction (vertical direction). In the direction). As shown in FIG. 2, the accumulation unit 8 is located below the first storage unit 2 in a state in which the first storage unit 2 is slid with respect to the separation unit 3. Therefore, when a sufficient amount of ice I is stored in the first storage part 2 and the salt water W is discharged from the discharge part 7, the first storage part 2 is slid as shown in FIG. The ice I stored in the water drops from the bottom opening 22 and is accumulated in the accumulation unit 8. The “substantially horizontal direction” is meant to include not only the horizontal direction but also a direction slightly inclined (for example, about ± 10 °) with respect to the horizontal.

  The accumulating unit 8 includes an accumulating unit main body 81 that receives the ice I falling from the first storage unit 2, and an agitation unit 82 that agitates the ice accumulated on the accumulating unit main body 81. The stacking unit main body 81 has a tapered shape with inclined sidewalls, and has an upper opening 811 that opens upward and a lower opening 812 that opens downward. Therefore, the ice I falling from the first storage unit 2 to the stacking unit 8 falls to the stacking unit main body 81 via the upper opening 811, slides down the inclined surface, and falls downward from the lower opening 812.

  The stirring unit 82 is provided in front of (above) the lower opening 812, and the ice I stirred by the stirring unit 82 falls from the lower opening 812. Thereby, softer ice I can be dropped from the lower opening 812. The configuration of the agitating unit 82 is not particularly limited as long as the ice I can be agitated, but in the present embodiment, a plurality of rotating bodies 821 having stirring blades are arranged, and each rotating body 821 is arranged. The ice can be stirred by rotating.

  Below the lower opening 812, a transport unit 9 for transporting the ice I falling from the lower opening 812 is provided. By providing such a transport unit 9, the ice I can be transported to a predetermined position. The transport unit 9 of the present embodiment includes a first transport unit 91 that transports the ice I in the horizontal direction, and a second transport unit 92 that transports the ice I transported by the first transport unit 91 upward. Yes. As shown in FIG. 3, the first and second transport units 91 and 92 include screw-like blades 912 and 922 on the circumferential surfaces of the elongated rotors 911 and 921. The ice I is conveyed by rotating around the axis. However, the configuration of the transport unit 9 is not limited to the above configuration as long as the ice I can be transported to a predetermined position, and for example, a belt conveyor or the like may be used. Moreover, the conveyance part 9 should just be provided as needed, and may be abbreviate | omitted.

  A belt conveyor 20 is provided below the front end portion of the second transport unit 92, and the box 30 packed with the seafood SF is transported by the belt conveyor 20. Therefore, the ice I transported to the tip of the second transport unit 92 falls and fits in the box 30, whereby the seafood SF is covered with the ice I. Then, the seafood SF is packaged in a state suitable for maintaining freshness by leveling the ice I and covering the ice I.

  According to the ice making device 1 as described above, since the first storage unit 2 is configured to collect the ice I in the first storage unit 2 by moving in a substantially horizontal direction, the device is installed (operated). ) Can be kept low. For this reason, the ceiling height restriction is relaxed, and it is easy to arrange indoors.

Therefore, after a sufficient amount of ice I is stored in the first storage unit 2 and the salt water W is discharged from the discharge unit 7, the first storage unit 2 is rotated as shown in FIG. The ice I stored in 2 falls from the upper opening 21 and is accumulated in the accumulation unit 8. The term “substantially horizontal” means not only horizontal but also a direction slightly inclined (for example, about ± 10 °) with respect to the horizontal.

  Such an ice making device 1 is configured to collect the ice I in the first storage unit 2 as the first storage unit 2 rotates. Therefore, as in the first embodiment described above, the height required to install (operate) the apparatus can be kept low, the ceiling height restriction is relaxed, and it is easy to arrange indoors.
