Description

[Detailed Description of the Invention] Industrial Application Field The present invention relates to a simulated hibernation tank device for seafood,
In particular, by subjecting seafood to pseudo-hibernation at low temperatures, the freshness of the seafood can be maintained in the state of live fish, making it possible to transport extremely fresh seafood at low cost, and improving the appearance of rows at stores, pleasing the eyes of customers. However, it is easy for customers to order their favorite seafood, and the water quality and temperature of multiple aquariums can be controlled individually, allowing different types of seafood to live in one unit of aquarium equipment. The present invention relates to an innovative pseudo-hibernation tank device for seafood, which allows a large amount of seafood to be stored in a small tank at high density while maintaining extremely high freshness.

Conventional Technology Conventionally, in order to keep seafood fresh and live, they are allowed to swim leisurely in a very large aquarium in order to keep the living environment not too different from the normal living environment of seafood. method was adopted. However, this method has the following major drawbacks, and it has been impossible for ordinary people to enjoy live fish.

(1) As fish and shellfish swim leisurely around the aquarium, their physical strength is exhausted, waste products accumulate in their bodies, which makes the fish taste bad, and they also get injured, causing damage to their bodies. The appearance of the product deteriorates and its appearance deteriorates.

(2) As the amount of excrement from fish and shellfish increases, water pollution becomes severe, and unless water quality is managed very well, fish and shellfish will develop diseases or die early.

(3) In order to maintain good water quality in the aquarium, the amount of water must be increased, and to do so, the volume must be increased according to the number of fish and shellfish, so the cost of the aquarium is reduced only. Not only is the cost of transporting seafood loaded onto a ship, aircraft, or vehicle extremely high, but it also requires a large amount of space relative to the number of seafood when placed at a store. It is impossible to stock it in a small store.

(4) Because the water tank is large and the equipment is complex, it is necessary to run it dry for about a week from the time the tank is installed to the time it starts to be used.

Furthermore, Japanese Patent Application Laid-Open No. 48-80400 discloses a method and device for transporting live eels, but in this conventional example, live eels can be transported by sea, unloaded, and transported on land only within a certain period of time. Sea water is used at sea, the sea water supply is stopped at ports, and ice is placed on land to allow the animals to hibernate and be transported on land for 10 to 20 hours. . Therefore, it is not possible to keep various types of seafood alive in a pseudo-hibernation state for long periods of time, and this technology makes it possible to provide ordinary live fish to customers in aquariums at sushi restaurants and restaurants. It is unrelated to the present invention, and is a different invention whose purpose, structure, and operation and effect are completely different from the present invention.

Furthermore, Japanese Patent Application Laid-open No. 49-35197 discloses an enzyme-supplemented live seafood preservation aquarium, but in this conventional example, liquid enzymes are added to the water in the aquarium to keep the seafood alive. This system supplies enzymes to the water and cools them using the low temperature of liquid enzymes, but this method alone cannot purify water at all, so it has the disadvantage that seafood cannot be stored in a live state for a long period of time. Therefore, this cannot be used for commercial purposes, and since it is not equipped with a temperature control device, temperature control is difficult, and the invention is completely different from the present invention.

In addition, Japanese Patent Publication No. 35-13862 discloses a fish farming device, but in the conventional example, each fish farming tank is configured in a tiered manner, but water flows into each fish tank sequentially from above. Therefore, each fish tank cannot be managed independently, and it has the disadvantage that it cannot be used for different species of fish and shellfish that are suitable for different waters (freshwater, seawater, etc.). In addition, some fish do not have a cooling device and do not disclose low-temperature pseudo-hibernation at all, so it has been completely impossible to preserve live fish in a pseudo-hibernation state for a long period of time.

In addition, Japanese Utility Model Publication No. 48-40558 discloses a multi-layer cultivation device for aquatic organisms, etc., but in this conventional example, each small aquarium container is arranged in tiers, but the water in the upper tier is lowered. This method makes it impossible to manage the water quality in each aquarium container, and therefore, it is not possible to mix and store freshwater or saltwater fish in one device. There were flaws. Further, this invention does not disclose a cooling device, and therefore is unrelated to pseudo-hibernation at low temperatures, and is completely different in purpose, structure, and operation and effect from the present invention.

Purpose The present invention was made to eliminate the drawbacks of the above-mentioned prior art, and its purpose is to provide an aquarium in which living seafood is housed in pseudo-hibernation at low temperatures; A filter tank that circulates the water in the aquarium to purify and filter the water so that the fish and shellfish can inhabit it in a healthy state, and a cooling device that maintains the temperature of the water to a level that causes the fish and shellfish to undergo pseudo-hibernation. A temperature control device that controls the cooling device to maintain the temperature of water in the water tank at a predetermined temperature, and a pump that circulates water from the filtration tank to the water tank via the cooling device. This makes it possible to store live seafood at a very high density in a narrow aquarium, preventing the physical strength of the seafood from being wasted, and preserving the good appearance of the seafood by preventing damage to its body. In addition, by keeping the seafood under low temperature, sugar accumulates in the body of the seafood, increasing its sweetness.It also significantly reduces the amount of excrement, prevents deterioration of water quality, and increases the number of seafood that can be accommodated per unit volume. The purpose of this invention is to significantly increase the amount of fish and shellfish in comparison with the conventional example, and to significantly reduce the cost of live seafood. Furthermore, in such a pseudo-hibernation aquarium device for seafood, the aquarium is constructed in a plurality of tiers, each independently, and arranged in a tiered manner such that the lower tier protrudes forward and the upper tier recedes backwards. To make it easier for customers to select their favorite seafood by making it easier for customers to see the seafood in an aquarium when they line up at a store, and to make it easier for customers to take out the seafood from the aquarium. Another purpose is to configure the filtration tank as a cartridge type that can be attached and detached independently to each aquarium, so that the type of filtration medium and filtration conditions can be changed depending on the type of seafood. The object is to be able to accommodate different types of fish and shellfish within a single aquarium device, and thereby to be able to hold a large number of types of fish and shellfish. Another purpose is to install a cooling device, a temperature control device, and a pump in each aquarium to enable separate water quality and water temperature control for each aquarium, making it possible to preserve different types of seafood in each aquarium. The goal is to ensure that the fish and shellfish in each aquarium can live in the best possible environment.

A temperature control dial 22, a thermometer 23, and various power switches 24 are attached to the front of each tank 2. Furthermore, various control electronic components, drive circuits, etc. are arranged within the switchboard 5a. Furthermore, a double door 28 is attached to the back side of the machine frame 11 so that it can be opened and closed.

Further, a fluorescent lamp 25 for illumination is attached to the upper part of the machine frame 11, and an air pump (not shown) for feeding air into the water 14 is attached to each water tank 2.

Effects The present invention is configured as described above, and its effects will be explained below. When using the simulated hibernation device 1 for fish and shellfish according to the present invention, water 14 is first poured into each aquarium 2. In this case, water 14 is water tank 2
If the water is different, it is possible to fill some with seawater and some with fresh water to accommodate the seafood 8 suitable for each water. Further, as shown in FIG. 4, if there are fish and shellfish 8 that can live in the same water quality and water temperature, a partition plate 9 or a partition shelf 1 may be placed in one aquarium 2.
0 can be put in and the seafood 8 can be sorted and stored by type. This prevents different types of seafood 8 from getting mixed up, and there is no risk of making a mistake when taking them out. Furthermore, by making the partition shelf 10 have four levels, upper and lower, as shown in FIG. 4, for example, up to four flat seafoods 8, such as flounder 8A, can be efficiently stored in one partition shelf 10. . Moreover, the sea bream 8B, shellfish 8C, shrimp 8D, etc. can be partitioned off by partition plates 9 and stored separately.

In this case, the conditions for the fish and shellfish 8 to live healthily in the water 14 include water temperature, pH, ammonia concentration,
It is essential that nitrite concentration, salinity concentration, and oxygen consumption (COD) are maintained appropriately. In addition to these, aerobic bacteria,
Bacteria must be present in the water in the required amount. It is necessary to maintain the water temperature at 2 to 3 degrees Celsius in order to put the seafood 8 into pseudo-hibernation, and even within this temperature range, the water temperature must be kept at a delicate level so that the seafood 8 does not catch diseases such as colds. Management is also required.

On the other hand, an appropriate filter material 18 is placed in the filtration tank 3 depending on the type of seafood contained in the aquarium 2, and as the filtration tank material 18, for example, ceramics is used. This is to purify the excrement of the seafood 8 by generating far infrared rays. Other types of filter media 18 having similar purposes are also used. Such adjustment of the filter material 18 is performed outside the fish and shellfish pseudo-hibernation device 1, and is carried out by a pipe 20 connected to the filtration tank 3, a pipe 19 connected to the pump 6, and a screw type connector 21. By being connected in communication, the filtration tank 3 is attached to the fish and shellfish pseudo-hibernation device 1 and performs its function.

When such preparations are completed, the pump 6, the cooling device 4, the temperature control device 5, the bacterial lamp, the fluorescent light 25, the air pump, etc. are turned on. As a result, the pump 6 is activated, and as shown by arrow C in FIG. After that, the water enters the cooling device 4 through pipes 20, 19, and 16, is poured from the top of the tank 2 through the pipe 15, and is supplied to the seafood 8 as clean, low-temperature water.

In addition, the water 14 immediately after leaving the aquarium contains bacteria that should be killed as well as bacteria that are useful for the seafood 8, but at this stage it is okay to kill all the bacteria. , ozone is generated from a germicidal lamp and irradiated onto the ozonated water 14. This results in water 14
enters the filtration tank 3 as completely sterile water. Then, aerobic bacteria and bacteria living in the filter medium 18 in the filter tank 3 are fed, and the water 14 becomes mixed with living substances preferable for the seafood 8.

In the cooling device 4, the water 14 is cooled to 2 to 3° C. and poured into the aquarium 2 at an extremely low temperature, so that the seafood 8 enters a state of pseudo-hibernation. In other words, the fish and shellfish 8 do not actively swim around and stay still, so they do not waste their physical strength.
You will not lose weight, your body will not be damaged, and you will continue to look good. Furthermore, since they are not active, the amount of excrement is very small, and as a result, the amount of contamination of the water 14 is also very small. Also, because the water temperature is conveniently low, seafood 8 accumulates sugar in its body to withstand this low temperature, and the meat becomes sweeter.The appropriate cool temperature makes the meat firmer and chewier, and the marbled fat improves the flavor. will increase.

In addition, by keeping the fish and shellfish 8 in a pseudo-hibernation state in the aquarium 2 in this way, it is possible to accommodate a large number of fish and shellfish 8 in the small volume of the aquarium 2 and maintain them in a healthy state. can. That is, compared to a conventional aquarium, the volume of the aquarium 2 can be reduced to one-tenth. Moreover, for this reason, the cost of the entire device including the water tank 2 can be reduced to about one-third of that of conventional products.

Next, the aquariums 2 of the fish and shellfish pseudo-hibernation device 1 according to the present invention are sequentially arranged from the bottom to the aquariums 2A, 2B, 2C, and 2.
As shown in D, the fish and shellfish 8 in each tank 2 are very easy to see because they are formed in a tiered shape, making it easy for customers to identify them when placed at restaurants, sushi restaurants, fish shops, supermarkets, markets, etc. It is convenient to specify and order seafood 8, and the appearance is very good, which can increase customer attraction.

Also, a cooling device 4, a temperature control device 5 and a pump 6
is attached to each water tank 2, so even if one pump 6 breaks down, there is no need to stop the entire system, and the pump 6
Since only the parts need to be repaired, the operating rate hardly decreases, which is advantageous.

Furthermore, by opening the door 28 and loosening the screws of the connector 21, the pipe 19 can be removed from the filtration tank 3 and attached/detached as shown by arrows A and B in FIG. Work such as cleaning the tank 3 and refilling the filter medium can be performed, and during this time, other water tanks 2 can be kept in operation, resulting in a high operating rate.

The temperature of the water 14 in the aquarium 2 can be adjusted using the temperature control dial 2.
2 to the desired temperature, and the temperature is automatically adjusted by the temperature control device 5 including a computer (not shown), so operation is extremely easy and there is almost no variation in water temperature. , the best temperature conditions are always obtained.
