  The present invention relates to a cold storage container used for storage, unloading, transportation, etc. of fish.

  When fish are stored in fish storage provided on fishing vessels, they are generally bulked. Sometimes it is soaked in water ice, the walls and insides of fish tanks are cooled with brine or cold air, and fish are frozen. Bulk loading of fish in fish storage can adversely affect the stability of the load and the stability of the fishing boat. In addition, since the unloading at the port is mainly manual work, a great effort is required. A long time for unloading is not preferable because it leads to a decrease in the freshness of the catch.

  There are Patent Literatures 1 and 2 as techniques for eliminating the heavy unloading work from the fish storage of a fishing boat and shortening the time and cost required for the unloading work.

  Patent Document 1 includes a cold storage container which is surrounded by a heat insulating wall in a fishing boat and in which a cold brine solution or cold air is introduced to cool the fish inside, and a fish storage container capable of being lifted in the cold storage tank is disposed. The structure of the fishing boat is described.

Fig.3 (a) is II schematic sectional drawing of FIG.2 (b), (b) is II-II schematic sectional drawing of FIG.2 (b).

  As shown in FIG. 2, the catch material cold storage container 1 has a container body 2 having a substantially rectangular parallelepiped shape in the illustrated example. The shape of the container body 2 is not limited to the illustrated example, and may be, for example, cylindrical or flat-bottomed spherical. An appropriate material is selected for the material of the harvested material cold storage container 1 according to the site, and is manufactured using, for example, stainless steel, aluminum, iron, reinforced plastic or the like. A catch inlet 3 is provided in the upper center of the container body 2. Here, the catch inlet 3 is a cylinder of a predetermined length, extends upward from the upper surface of the container body 2 and has an opening at the upper end. The shape and size of the catch 3 are designed as needed.

  A lid 6 is provided for closing the upper end opening of the catch inlet 3. The lid 6 can be opened and closed. It is opened when the catch is put in and out, but it can be closed otherwise.

  Furthermore, a suspension ring 7 is provided on the upper surface of the container body 2. The suspension ring 7 is used to lift by the working machine such as a crane when moving the catchment for cold storage container 1. In the illustrated example, two suspension rings 7 are disposed on opposite sides of the catch inlet 3. The shape, the number, and the arrangement of the hanging ring 7 are not limited to the illustrated example, and are set as needed.

  Referring to FIG. 3, the container body 2 has a storage space 2f formed therein. The storage space 2 f is surrounded by the container wall on the side, bottom and top except the catch inlet 3. The container wall has a double wall structure comprising an outer wall 2a and an inner wall 2b. A refrigerant space 2c having a predetermined thickness is formed between the outer wall 2a and the inner wall 2b.

  As an example, when the fish food cold storage container 1 in which the refrigerant space 2c is not filled is stored in a fish store, the brine liquid supply line 14a shown in FIG. 1 is connected to the refrigerant supply port 2d to make the brine liquid refrigerant space 2c. It may be filled with Preferably, the discharge line 14b is further connected to the refrigerant outlet 2e to circulate the brine liquid through the refrigerant space 2c, thereby reliably filling the brine liquid into the refrigerant space 2c and rapidly reducing the catchment cold container 1 It can be cooled.

  As another example, you may store the fishery cold storage container 1 with which the refrigerant | coolant was beforehand filled in the fish storage. The type of refrigerant is not limited to the brine liquid, and may be selected as needed.

  Thereafter, the fish storage container 1 is totally cooled by, for example, cooling the fish hold by the cooling facility shown in FIG. At the same time, the refrigerant in the refrigerant space 2 c of the fish food cold storage container 1 is also cooled. While the fishery cold storage container 1 is stored in the fish storage, the refrigerant in the refrigerant space 2c is maintained at the same temperature as the fish storage. As another example, even when fish hold is cooled with water ice, the fish food cold storage container 1 is placed in the fish hold so that it has the same temperature as water ice as a whole including the refrigerant. .

  As shown in FIG. 2 and FIG. 3, each of the refrigerant supply port 2d and the refrigerant discharge port 2e may be sealed by a suitable cover that can be attached or detached or not when the refrigerant is not supplied or discharged. it can.

After being unloaded from a fishing boat, the fish food cold storage container 1 of the present invention can be transported as it is and distributed to the market. Therefore, it is useful to display and / or store trace information on the surface of the fish catcher 1.

  In the simplest example, the trace information display unit and / or the storage unit 5 is a sheet or plate for writing the trace information. As another example, trace information is recorded as a code in a two-dimensional code, an NFC tag or the like, and read by an appropriate reader. Alternatively, as another example, trace information is stored in an IC chip and written or read by an appropriate write / read device.

  Fig.4 (a) (b) is the schematic sectional drawing which showed the use condition of the catch material 1 of this invention. FIG. 4 (a) is an example of the use condition while stored in the fish storage of the fishing boat shown in FIG. For example, in the storage space 2f, the catch is stored together with an appropriate amount of water ice. Water ice is not essential, and depending on the type of fish, appropriate methods will be taken. The refrigerant space 2c is filled with an appropriate refrigerant C supplied from the refrigerant supply port 2d. When the refrigerant C is charged, the refrigerant supply port 2d is sealed. The temperature of the refrigerant C is determined by the temperature of the fish storage in which the fish food cold storage container 1 is stored. The fish is frozen or cooled at an appropriate temperature depending on the temperature of the refrigerant C.

  Between the time it is caught and the time it is unloaded, the cold matter storage container 1 is cooled by the fish storage cooling system. Preferably, the gas supply pipe 16 is inserted into the storage space 2 f through the through hole 6 b of the lid 6, and nitrogen gas is injected into water ice from the injection nozzle 17 provided at the tip thereof. As a result, the dissolved oxygen in the water ice is degassed and replaced with nitrogen, whereby the water portion of the water ice becomes nitrogen dissolved water. Thereby, it is possible to prevent the oxidation of the catch and maintain the freshness for a long time.

  FIG. 4 (b) is an example of the use condition during and after unloading. At the time of unloading, the refrigerant space 2c is filled with the cooled refrigerant C, and the refrigerant supply port 2d, the refrigerant discharge port 2e, the lid 6 and the through hole 6b are all sealed. After the unloading, while the temperature of the refrigerant C in the refrigerant space 2c is kept low, a cold storage effect of keeping the storage space 2f at a low temperature is obtained. Therefore, even in an environment without cooling equipment, it is possible to prevent the decrease in the freshness of the catch immediately.

  In the transportation process after unloading, the refrigerant C can be cooled again by storing the fish food cold storage container 1 in an appropriate cooling facility such as a cold storage warehouse. By repeating this for every predetermined time, for example, the storage space 2f of the fish food cold storage container 1 can be kept at a low temperature for a long time. As a result, the freshness of the catch can be maintained.

  As described above, according to the present invention, since it is possible to distribute the fish while keeping the fish in the fish storage cold container 1, it is possible to keep the freshness of the fish well without damaging the fish.

  In addition, it is also possible to utilize it as a cold storage container and distribution container of the harvest in agriculture.
