Description

[Detailed Description of the Invention] The present invention relates to an air transportation container for fish roe, etc., and in particular is an air transportation container for raising and preserving materials sensitive to temperature differences such as fish roe for a long period of time at a constant temperature.

Although various types of containers of this type have been developed in the past, their development has been extremely slow because it has been considered impossible to transport fish eggs over long periods of time.

An essential condition for air transport of fish eggs is to maintain a constant temperature, and when transporting tuna eggs spawned in the Mediterranean Sea by air, which is the direct purpose of this invention, it is necessary to maintain the temperature at 15 degrees Celsius, and the allowable temperature difference is ± It is said to have occurred once.

If you do not strictly adhere to the range of plus or minus 1 degree, the eggs may develop abnormalities, which will hinder the process of turning them into eggs.

Moreover, for air transportation, it is necessary to maintain that temperature for at least 20R.

However, conventional shipping containers do not have the ability to maintain such delicate temperatures for long periods of time, and even the inside of the container has a critical flaw in that it varies by more than ±1 degree depending on location. there were.

In addition, it is desirable to be able to adjust the temperature control range within as narrow a range as possible;
It is difficult to believe that the quality of fish roe is being adequately controlled at just the last moment.

Not only fish eggs but also young fish and young fish that are sensitive to temperature changes, and that lack temperature tolerance or that live in cold water, require control within a narrow temperature range.

The purpose of this invention is to provide a new container for air transportation of fish eggs, etc., which eliminates the drawbacks of the conventional technology as described above. Furthermore, since the inside of the container can be uniformly cooled or heated, subtle differences in temperature can be maintained.

The present invention will be described in detail below based on embodiments shown in the drawings.

Figure 1 shows A- of the container for air transport of fish eggs, etc. related to the present invention.
It is a sectional view taken along line A, and FIG. 2 is a sectional view taken along line BB.

A container 10 for air transport of fish roe, etc. is comprised of a fish roe storage chamber 11, a cooling chamber 12, and a control box 14 equipped with a fan 13, a thermostat, and a battery.

A ventilation passage 15 for circulating cold air is provided around the fish roe storage chamber between the container and the wall surface of the container.

The cooling chamber 12 and the fish roe storage chamber 11 are partitioned by a wall, and the upper end of the wall is provided with ventilation holes 16a and 16b for blowing air.

Send. A fan 13 driven by a battery is arranged in the air hole 16a, and the cool air inside the cooling chamber 12 is sent into the ventilation path 15 through the air hole 16b by the operation of the fan 13.
15a, 15b, and 15c around the outer periphery of the roe storage chamber, it is sent to the cooling chamber through the ventilation hole 16a.

The ventilation passage 15 is a dead end wall 15d at the center of the partition wall.
is provided, and the cold air coming out from 16b is forcibly sent into the cooling chamber.

The fan 13 operates according to the temperature of the fish roe storage chamber detected by the temperature sensor of the control box, and the temperature can be set within a range of 0.5 degrees.

Dry ice 12a is stored in the cooling chamber 12 as a cooling source.

Since the bottom of the cooling chamber 12 is at an extremely low temperature,
It is also possible to maintain extremely low temperatures by continuously driving the fan 13.

In addition, the cold air coming out of the cooling chamber always surrounds the fish roe storage chamber, so the storage chamber is cooled from the entire surrounding area, resulting in homogeneous cooling as a whole, with local temperatures becoming extremely low. There is no need to worry, and since the cooling is done indirectly by the cold air cooled by the cooling source, the rate of temperature drop will not be rapid.

Cold air has a higher specific gravity than warm air, and cold air generally does not flow out from the ventilation holes in the upper part. Since there is a risk that cold air may flow into the ventilation path, it is also possible to provide a damper particularly at the mouth of the hole to prevent the cold air from flowing in and prevent the temperature from rising or falling unexpectedly.

Furthermore, it is also possible to separate the cooling chamber and install a heat source.

In this case, instead of the ventilation holes provided at the top end of the partition wall, it is necessary to provide ventilation holes at the bottom end of the partition wall.

Depending on the transportation method and route, both a heat source and a cooling source may be required, so as shown in FIG.
, 16d, and block the ventilation holes with a damper when not in use.

The container body is made of a heat insulating material 19, and a lid 20 that can maintain airtightness is provided at the upper end.

Fish roe to be transported are first placed in a plastic bag 21, about half of which is made up of sea ice (or fresh water), and the rest is supplemented with oxygen.Then, the opening is closed with a rubber band, etc., and then placed in a fish roe storage room. It will be done.

Since the present invention has the structure detailed above, it is possible to maintain fish eggs etc. at a constant temperature for a long period of time, and it is also possible to almost eliminate temperature differences inside the container, which has not been possible until now. This has the practical effect of making it possible to transport tuna roe by air from the Mediterranean Sea.
