Description

[Detailed Description of the Invention] [Industrial field of application] The present invention relates to a storage device for transporting and storing live fish, shrimp, crabs and other seafood as they are alive, and particularly to a storage container of a fixed volume. The present invention relates to a seafood storage device capable of storing a larger amount of seafood for a long time without degrading the quality.

[Prior Art] Conventionally, in the case of transporting and storing fish and shellfish such as Thailand, flat fish, shrimp, and crab while alive, a tank-shaped water tank having a hatch at the upper end is attached to a transportation vehicle such as a truck. A method is adopted in which normal temperature water is injected into this aquarium to store seafood in the tank, and in order to accommodate more seafood, in some cases, air is constantly supplied.

[Problems to be solved by the invention] However, in the conventional method of this kind, the number of fish and shellfish that can be stored in the aquarium is determined by the bottom area of the aquarium, and even if the aquarium is deep, There is a problem that the storage capacity of seafood cannot be increased.

That is, for example, when live fish are stored and transported or stored in an aquarium, the live fish are collected and live at the bottom of the aquarium and are not dispersed in the depth direction. For this reason, if more than the number of live fish determined by the bottom area of the aquarium is stored, it will be oxygen deficient even if air is constantly supplied, and live fish cannot be transported or stored alive. There's a problem.

On the other hand, in the case of crustaceans such as shrimp and crab, even if a slightly excessive amount is stored in the aquarium, it is less likely to die as live fish, but if the crustaceans are piled up and down, There is a problem that the merchandise is cut off by itself and the commercial value is extremely reduced.

In addition, conventionally, the method of pouring room temperature water into a water tank and transporting and storing it in a normal habitat has been adopted, so a certain amount of water is always required, and the amount of movement of seafood in the water tank increases. In addition to the fact that the water is extremely dirty and the amount of water is large, a large capacity water purification device is required,
There is also a problem that the air supply device is always required and the device becomes large. In addition, since the amount of movement of fish and shellfish in the aquarium is large, there is a problem that even if the fish and fish can be transported and stored alive, they become thin and their quality deteriorates.

The present invention has been made in view of the current situation, and it is possible to reliably transport and store a larger amount of seafood alive with a small amount of water, without degrading the quality,
It is an object of the present invention to provide a seafood storage device having a simple device configuration and capable of significantly reducing transportation and storage costs.

[Means for Solving the Problems] As a means for achieving the above-mentioned object, the present invention is arranged in a plurality of storage spaces formed in a storage cabinet so as to be drawn out, and stacks seafood in a normal habitat state. A plurality of containers that can be accommodated in a plane without the need; a water supply cooling means that supplies cooling water to each of these containers and keeps the seafood contained in the containers in an optimum low temperature range; overflow water from each of the containers Water purifying means for collecting and purifying the water, and supplying the water to the feed water cooling means;
It is formed into a rectangular box shape with a depth that allows seafood to be submerged in a normal habitat, and one of its corners has a water supply port and its diagonal corner has a drainage port, and the water supply is cooled. The means comprises a water supply generation mechanism that generates a plurality of types of water supply with different water temperatures, a supply mechanism that individually supplies each of these water supplies to an arbitrary container, and a water supply amount control mechanism that controls the water supply amount to each container. The water supply generating mechanism includes a single water cooler, and at least one heating tank that heats the water supplied from the water cooler by a heater to generate water having a water temperature different from the water supplied from the water cooler. It is characterized in that it is configured from.

[Operation] In the seafood storage device according to the present invention, the seafood is distributed in a planar manner in a plurality of containers without being piled up in a normal habitation state, and the seafood is supplied from the water supply cooling means. The cooling water supplied keeps the temperature in the optimum low temperature range.

By the way, by keeping the seafood in the optimum low temperature range according to its type, the amount of exercise becomes extremely small and becomes a nap state, and if the skin surface is in contact with water, even if it is stored in a dense state, It has been confirmed by experiments by the present inventors that it can be kept alive for a long time without deterioration of quality. Therefore, by using the container as described above, it is possible to transport and store without deteriorating the quality. In addition, each container is formed so that the seafood is submerged in a normal habitation state, and the amount of water is considered to be as small as possible, so in combination with being able to store it in a dense state, The amount of water used can be extremely reduced, and the storage efficiency per unit volume can be significantly improved. Further, since the amount of exercise of fish and fish is small and the amount of water contamination is small, the water purification means can be downsized in combination with the small amount of water used. Moreover, since the seafood is distributed and stored in each container, different types of seafood can be transported and stored at the same time.

In addition, each container is formed in a rectangular box shape, and a water supply port is provided at one corner thereof, and a drainage port is provided at a diagonal corner thereof, so that the water supply port is provided throughout the container. A water stream is formed from the head to the drain. For this reason,
Water does not settle in the container, so fresh and clean water can always be supplied to seafood. In addition, since fish have the habit of swimming toward the upstream of the water stream, and this state is the most mentally stable, the water stream is formed in the container to reduce stress on the seafood and prevent deterioration of quality. You can

Further, since the water supply cooling means has a function of generating a plurality of types of water supply having different water temperatures, it is possible to simultaneously transport and store a plurality of seafood having different optimum low temperature regions, and control the water supply amount. Since it has a function to do so, it is possible to easily obtain the optimum water supply amount according to the type of seafood.

Further, since the water supply generation mechanism of the water supply cooling means is not configured by a plurality of water coolers but is configured by a single water cooler and at least one heating tank, the device configuration is simplified. Can be miniaturized.

In FIG. 3, reference numeral 39 is a drain valve attached to the storage tank 7.

As shown in FIGS. 4 and 5, each container 11 is made of transparent plastic and has a rectangular box shape.
At the lower end of one of the corners, there is provided a supply port 40 through which the circulating water whose flow rate is adjusted by the flow rate adjusting valve 13 is supplied through a water supply hose 14, and at the upper end of the diagonal corner. An overflow port 41 to which the overflow pipe 16 is connected is provided. The supply port 40 also serves as a discharge port by disconnecting the connection with the water supply hose 14. As the water supply hose 14 and the overflow pipe 16, for example, a telescopic hose wound in a spiral shape is used so as not to hinder the withdrawal of the container 11.

The depth of each container 11 is set so that the seafood is submerged in a normal living state, for example, about 5 cm for flat seams and about 15 cm for hair crabs, and a particularly large depth. In the case of a large fish or the like requiring a size, one of the intermediate stage mounting plates 10 is removed, and the fish is arranged over two stages.

Next, the operation of this embodiment will be described.

When storing seafood, first open the door 2 of the storage box 1,
Each mounting plate 10 is pulled out to the door 2 side. Then, after placing the container 11 containing the seafood on each mounting plate 10, the water supply hose 14 is connected to the supply port 40 thereof, and the overflow pipe 16 is connected to the overflow port 41, respectively, and each mounting plate is connected. 10 is pushed into the storage case 1 and brought into the state shown in FIGS. 1 and 2.

Next, the water supply pump 19, the circulation pump 30, and the compressor 32 are started. When the circulation pump 30 is started, the circulating water in the storage tank 7 is filtered by the strainer 29, then guided to the water cooler 34 through the circulation inlet pipe 31, and cooled to a predetermined temperature. The cooled circulating water is returned to the storage tank 7 via the circulation outlet pipe 38. Thereby, the circulating water in the storage tank 7 is gradually cooled.

On the other hand, when the water supply pump 19 is started, the circulating water in the storage tank 7 is guided to the main strainer 24 or the auxiliary strainer 25 via the water supply pipe 20, and after being filtered there, the water supply header.
Sent to 12. Then, after the flow rate is adjusted by each flow rate control valve 13, it is sent to each container 11 via a water supply hose 14.
Overflow water from each container 11
It is collected in the water collecting pipe 17 via 16 and is then returned to the storage tank 7 after the dirt is removed by the filter unit 9.

The temperature of the water supplied to each container 11 is constantly detected by the temperature sensor 22 provided in the water supply pipe 20, and is maintained at an optimum low temperature according to the type of seafood.

Then, since the water cooled to the optimum low temperature is supplied to each container 11, the seafood in the container 11 enters a nap state in which the amount of exercise is extremely reduced, and is stored for a long time without deteriorating the quality. Can be kept. In addition, since it is in a nap state, it can be stored in each container 11 in a quite dense state and can be stored in multiple stages, so that a large amount of seafood can be stored in a small installation area. Also, each container
The depth of 11 is sufficient for the seafood to be submerged in normal living conditions, so the required amount of water can be significantly reduced. Therefore, the transportation cost can be significantly reduced when used for transportation of seafood.

Further, since the amount of exercise of the seafood is extremely reduced, the amount of dirt on the water is small, the filter unit 9 can be downsized, and the filter unit 9 can be replaced by pulling it out to the door 2 side, which facilitates the replacement work. .

Further, since the required amount of water is small, the water cooling means for cooling the water can be downsized, and quick and stable water temperature control can be performed.

In addition, since the seafood is distributed and stored in each container 11, different types of seafood can be stored at the same time, and moreover, each flow rate control valve 13 can easily obtain an optimum amount of water supply according to the type of seafood. You can also take out seafood
Water supply can be stopped separately. Then, stop the water supply and remove the water supply hose 14 from the supply port 40.
Since the water in 11 is completely discharged from the supply port 40, there is no obstacle when taking out the seafood. Further, since each container 11 has a structure that can be pulled out to the door 2 side together with the mounting plate 10, it is easy to take in and out seafood.

By the way, when the seafood is put into a nap state in which the amount of exercise is extremely small, the optimum low temperature depends on the type of the seafood. For example, the optimum low temperature for Omar shrimp and certain types of crab is -2 ° C, the optimum low temperature for other types of crab and shellfish is 0 ° C, the optimum low temperature for flatfish and certain lobsters is 5 ° C, and the optimum temperature for fish such as eels. The low temperature is 7 ° C. Also, some lobsters require an optimum low temperature of 13 ° C.

At the same time, the storage 1
When it is housed inside, the water temperature of the circulating water supplied to each container 11 must of course be adjusted accordingly.

FIG. 6 shows a second embodiment of the present invention in consideration of such a point, and two kinds of watering temperatures can be obtained.

That is, as shown in FIG. 6, one end of a branch pipe 52 having an on-off valve 51 is connected to the downstream side of the temperature sensor 22 of the water supply pipe 20, and the other end of the branch pipe 52 has a heater 53. It is connected to a built-in heating tank 54, and overflow water in the heating tank 54 is returned to the storage tank 7 via an overflow pipe 55.

The circulating water in the heating tank 54, as shown in FIG.
The heater 53 receives a signal from the temperature sensor 56 on the outlet side of the heating tank 54.
The circulating water is controlled to a constant temperature by a temperature display setting device 57 for controlling the above, and this circulating water is supplied to the inlet side of an arbitrary flow rate control valve 13 separated from the water supply header 12.

With such a configuration, two types of watering temperatures can be obtained, and the seafood having different optimum low temperatures can be stored in the storage case 1
Can be housed at the same time. Further, if a plurality of heating tanks 54 of this type are provided, it is possible to obtain watering temperatures of three or more types.

FIG. 7 shows a third embodiment of the present invention.
The method is different from that of the embodiment so that two kinds of watering temperatures can be obtained.

That is, as shown in FIG. 7, one end of a feed pipe 62 having a water feed pump 61 is connected to the storage tank 7,
The other end of the feed pipe 62 is connected to a heating tank 54 containing a heater 53. Further, as shown in FIG. 7, a return pipe 64 having a flow rate control valve 63 is connected to a position of the delivery pipe 62 on the delivery pump 61 outlet side, and the amount of water required for the heating tank 54 or more is equal to or larger than that required. The residual water of 1 is returned to the storage tank 7. The other points are the same as those of the second embodiment.

Even with this structure, the same effect as that of the second embodiment can be expected.

FIG. 8 shows a fourth embodiment of the present invention.
The method is different from that of the embodiment and the third embodiment so that two kinds of watering temperatures can be obtained.

That is, at the water pump 19 outlet side position of the water supply pipe 20,
As shown in the figure, one end of a branch pipe 72 having an on-off valve 71 is connected, the other end of the branch pipe 72 is connected to a heating tank 54 containing a heater 53, and overflow water in the heating tank 54 is connected. Is returned to the storage tank 7 via an overflow pipe 74 having an opening / closing valve 73.

On the other hand, as shown in FIG. 8, the circulating water heated in the heating tank 54 is fed by the feed pump 61 through the feed pipe 62 and separated from the water feed header 12. Flow control valve 13
It is designed to be supplied to the entrance side of. The other points are the same as those of the third embodiment.

Even with this structure, the same effect as that of the second embodiment can be expected.

FIG. 9 to FIG. 11 show a fifth embodiment of the present invention, which is different from the above-mentioned embodiments adopting an aquarium system in which the seafood is kept at an optimum temperature by a shower system.

That is, in the case of the present embodiment, the container 11, the flow rate control valve 15 and the overflow pipe 16 are removed from the inside of the storage case 1 of the first embodiment shown in FIGS. 1 and 2, and instead of this, On each platen 10, while placing the seafood saucer 81 that stores the seafood in a plane without stacking vertically,
A shower nozzle 82 for sprinkling water on the seafood is arranged above each seafood saucer 81, and a drain port 83a at the downstream end is provided at each water collection port 17a of the water collection pipe 17 at a position directly below each mounting plate 10. The water receiving members 83 to be connected are arranged respectively. Then, the water from each shower nozzle 82 is sprinkled on the seafood on each seafood saucer 81 to maintain the skin surface of the seafood in a wet state and to bring the seafood to an optimum low temperature according to its type. The water is held, and then collected by the water receiving member 83 and collected in the water collecting pipe 17.

As shown in FIG. 11, each seafood saucer 81 has a depth
It has a shallow rectangular container shape of about 10 cm, and has a small number of small holes 81a at its bottom, and a large number of large holes 81b at a position slightly above the lower end of the peripheral wall. ing. Then, in the state where water is sprayed from the shower nozzle 82, the water is collected up to the position shown by the chain line L in FIG.

The rest of the configuration is the same as that of the first embodiment, and the operation is also the same except for the difference between the shower system and the water tank system.

By the way, by keeping the seafood in the optimum low temperature range depending on its type, the amount of exercise becomes extremely small and it becomes a nap state.In this nap state, even if the seafood is not stored in water, the seafood is It has been confirmed by experiments conducted by the present inventors that the skin surface of a kind can be kept alive for a long period of time without deterioration in quality if the skin surface is kept moist. And at that time, it is possible to keep a part of the skin surface of the seafood constantly in contact with water, rather than simply sprinkling water, for a long time without deterioration in quality. This has been confirmed by experiments by the present inventors.

Therefore, even if the shower method as in the present embodiment is adopted, it is possible to expect substantially the same effect as in the case of the water tank method. Moreover, the required amount of water can be reduced as compared with the case of the water tank system, which is particularly suitable for use in transportation.

Further, the shower system of the present embodiment can be easily changed to a water tank system by replacing some of the components, so that half of the inside of the storage case 1 can be a shower system and half can be a water tank system. . Further, as in the case of the water tank system, the temperature of water sprinkled from each shower nozzle 82 can be set to a plurality of temperatures according to the optimum low temperature of seafood.

[Effects of the Invention] As described above, the present invention disperses and stores fish and shellfish in a plurality of containers, and cools the water supplied to each container by the water supply cooling means. Since it is kept in the optimum low temperature range according to the type,
More seafood can be stored alive for a long time with a small amount of water and without deterioration in quality.
In addition, the device configuration is simple, and transportation and storage costs can be significantly reduced.

In addition, since each container is formed in a rectangular box shape and a water supply port is provided at one corner and a drainage port is provided at the diagonal corner, water does not settle in the container and is always fresh. It is possible to supply clean water to the seafood, and to reduce the stress of the seafood due to the water flow formed in the container, and to suppress the deterioration of the quality of the seafood.

Further, since the water supply cooling means has a function of generating a plurality of types of water supply having different water temperatures, it is possible to simultaneously store a plurality of types of seafood having different optimum low temperature regions, and the seafood storage device can be supplied with high supply. It is especially effective for small-scale transportation of seafood and as a showcase.

Since the water supply cooling means also has a function of controlling the water supply amount, the optimum water supply amount according to the type of seafood can be easily obtained.

In addition, since the water supply generation mechanism of the water supply cooling means is configured by a single water cooler and at least one heating tank, the device configuration is simple as compared with the case of using a plurality of water coolers. It is possible to reduce the size of the device and reduce the manufacturing cost.
