Description

[Detailed explanation of the invention] <Industrial application field> The invention is based on the ability of crustaceans such as shrimp and crabs, shellfish such as oysters, and fish such as blowfish to remain alive for a certain period of time in the atmosphere. The present invention relates to containers for transporting live seafood, etc., which can be transported, sold at stores, and kept in a living state for a long period of time until cooked.

<Prior Art> As dietary habits become more diverse, consumers' demands on the freshness of seafood are becoming more stringent than ever. Especially now that the gourmet food boom has become popular, the technology for transporting live fish is also making remarkable progress. As a means of transporting large amounts of seafood, there are live fish transport vehicles that transport while supplying oxygen to seawater. The purpose of this invention is not to transport such large quantities of seafood, but rather to transport only the amount needed for household consumption (for example, in the case of prawns, a few to several dozen prawns). Put it in
The purpose is to send the animal alive in a relatively small volume that can be sold at department stores. Conventionally, such a mode of transportation has only been carried out, for example, in the winter, when shrimp were placed in sawdust in a container and sent.

<Problems to be solved by the invention> The above-mentioned conventional transportation method cannot be carried out in the summer when the outside temperature is high, and there is If you want to put ice in it and make it durable for long-term transportation in the summer, you will need a large container such as ice, and the storage space will have to be increased accordingly, making the container larger as a whole, which is impractical. In addition, the oxygen inclusion method used for eel, dojiyo, flounder, etc.
When the water is stationary (that is, when the water is not shaking), it is deficient in oxygen and cannot be transported over long distances. In any case, the containers for transporting live seafood, etc. that have been considered in the past are not in a form that would be delivered to individual households as gifts, etc., and the containers for transporting live seafood, etc. There was nothing I could do.

<Means for solving the problem> Therefore, in the present invention, we have developed a transportation container that can transport live seafood to homes, etc. The structure is characterized in that a frozen oxygen regulating supply section 3 sealed with an oxygen-permeable packaging bag 2 is provided at the bottom of a container 1 having a heat-insulated storage space for live shrimp, etc.

The insulated container 1 referred to in the present invention is a container that can maintain the internal storage space for live seafood in a state close to hibernation at around 10°C, regardless of the outside temperature. Examples include synthetic resin foams such as styrene foams, cardboard boxes, multiple containers made of plastics, and the like.

In addition, the porous material 4 referred to here has the function of containing and holding hydrogen peroxide solution or water when frozen, and the function of gradually thawing the frozen hydrogen peroxide solution, such as a sponge board, etc. These include inorganic porous particles such as sponge chips and perlite powder. When the porous material 4 is plate-shaped or sheet-shaped, it is effective to provide a plurality of holes near the center.

The frozen oxygen regulating supply section 3 is suitable for implementing the present invention, and is composed of a porous material 4 impregnated with a frozen hydrogen peroxide solution and an oxygen generating agent powder 5 below the porous material 4. What is the oxygen generating agent powder 5? It is a compound that acts on the hydrogen peroxide solution to generate oxygen, and includes manganese dioxide. Ferric oxide salt and fluorine are added to the hydrogen peroxide solution to serve as a reaction regulator for manganese diacid. In addition to this, the frozen oxygen regulating supply section 3 of the present invention also includes a porous material 4 impregnated with water and frozen.
Sodium peroxide powder can also be used as the oxygen generating agent powder 5 at the bottom. These are placed in a tray and housed in an oxygen permeable packaging bag with the opening sealed.

The oxygen-permeable packaging bag 2 is made of a synthetic resin sheet that allows the ventilation of generated oxygen, but prevents the internal water and compounds after the reaction from leaching out.

<Function> When such a container for transporting live seafood, etc. is filled with seafood such as prawns that have been hibernated by lowering the water temperature in advance, along with a filler such as sawdust, an oxygen-permeable packaging bag is formed at the bottom. The impregnated and frozen hydrogen peroxide solution and water in 2 are gradually thawed while contributing to the refrigeration of seafood, and the thawing solution such as hydrogen peroxide solution and water that is leached as a result of thawing becomes oxygen generating powder. 5 to generate oxygen. At this time, the porous material 4 has the effect that the thawing solution does not come into immediate contact with the oxygen generating agent powder 5, but gradually leaches out and reacts with the oxygen generating agent powder 5. The generated oxygen is supplied to the live shrimp, etc. in the storage space through the micropores of the oxygen-permeable packaging bag 2, and water, etc. is retained within the bag. In this manner, the frozen oxygen regulating and supplying section 3 maintains the low temperature of the heat-insulating housing space for live shrimp and the like, and also functions to supply oxygen.

<Examples> Examples of the present invention will be described in detail below with reference to the drawings.

FIG. 1 is an exploded perspective view of a container for transporting shellfish, etc. of the present invention, and FIG. 2 is a partially cutaway perspective view showing how the container accommodates prawns. FIG. 3 is an enlarged sectional view of the central part.

The container for transporting live seafood etc. shown here has an internal volume of about ^6000cm3 , and is small enough to accommodate about 10 to 20 tiger prawns and be sent by courier. be. The container 1 is made of polystyrene foam with excellent heat insulation performance, and has a plate-shaped lid 1b on the top, and the container body 1a below the lid 1b has a rectangular box shape.

A frozen oxygen regulating supply section 3 is provided on the inner bottom surface of such a heat insulating container. A porous material 4 impregnated with frozen peroxide water and an oxygen generating agent powder 5 are housed inside a thin flat tray 6, and these are further housed in an oxygen permeable packaging bag 2. The opening is sealed. The oxygen generator powder used here was approximately 25 g of manganese dioxide. The porous material 4 is an open-cell polyethylene foam. A large number of through holes 8 are provided near the center.

In this embodiment, a flexible foam (sponge) sheet 10 is used to separate the frozen oxygen regulated supply 3 and the filling material 9.

On the foam sheet 10 in the container for transporting live seafood, etc. having the structure as described above, sawdust of the filler material 9, which has been pre-cooled to a low temperature of 5°C, is spread over the entire surface to a thickness of about 30 mm. Place the tiger prawns 11, which have been brought into a hibernating state by lowering the water temperature to around 10°C, on top of them.
Furthermore, I filled the container with sawdust on top of the prawns, covered it, and taped the gaps.

As a result of being placed under transportation conditions (30°C) in this packaging mode, oxygen began to be generated 7 to 8 hours after shipment, and oxygen was supplied for about 15 hours at an oxygen generation rate of 200 ml/h, and 30 minutes after packing. I was able to send the prawns alive for about an hour.

<Effects of the invention> With the container for transporting live seafood, etc. of the invention, it has become possible to easily deliver live tiger prawns, etc. to the hands of consumers.

It is useful in that it is compact as a whole and can provide live seafood as gift products, etc., while maintaining low temperature and oxygen supply, and has the effect of increasing the added value of seafood.
