JPH0365488A - Loading method in loading small amount in fresh fish carrier - Google Patents

Abstract

PURPOSE:To prevent fluctuation and to carry fish without damaging it by expanding an air bag having a capacity slightly smaller than a remaining load ing capacity of a fish hold in the fish hold and by pouring sea water so as to make the fish hold into the water filled state. CONSTITUTION:By filling the remaining space in a fish hold 3 with an air bag 2 is loading a small amount, the space is filled with a small amount of sea water. As a result, fluctuation of sea water can be prevented and damage on fish can be also prevented.

Description

DETAILED DESCRIPTION OF THE INVENTION (Field of Industrial Application) The present invention relates to a loading method for a fresh fish carrier when a small amount of cargo is loaded.

(Prior art) Currently, in many cases, seawater and ice are put together with fish in fish holds, and the fish are transported refrigerated in the so-called water ice state. Especially when a small amount of cargo is loaded, the rolling or pitching of the ship causes the water in the fish hold to shake violently, causing the fish to be stirred up and severely damaged.

Therefore, the methods that are currently being used to prevent this are listed below: ■ Raise the water level as much as possible to prevent the fish tank from shaking upwards by leaving no room in the fish hold (full water method); ■ Maintaining the water level low, A method of keeping ice above the water level and suppressing the fluidity of water ice to prevent it from shaking (drainage method) ■ A method of preventing shaking by erecting partition plates and dividing the fish hold into several blocks (partition method) law) etc.

(Problem to be solved by the invention) Problems with the above method are listed below.

[Full water method] 1. A large amount of ice is required to prevent the temperature from rising due to the injection of large amounts of seawater, resulting in a significant increase in costs.

2. When the other fish holds are empty, only one fish hold becomes full of water, which raises the ship's center of gravity and makes the ship unstable.

[Drainage method] 1. The weight of the ice presses on the fish, causing damage to the fish.

2. Ice comes into direct contact with the fish body, causing so-called ice burn.

3. Rising water levels due to melting ice must be constantly monitored.

[Partition method] 1. The work is troublesome and it is difficult to put fish and ice evenly into each block.

2. Since it does not completely prevent rocking, some damage may occur.

(Means for solving the problem) An airbag having a volume slightly smaller than the remaining loading capacity of the fish hold is inflated in the fish hold and seawater is injected to fill the fish hold to prevent the fish from shaking.

(Function) The key point of the present invention is that by filling the remaining space in the fish hold with airbags when a small amount of cargo is loaded, it can be filled with a small amount of seawater, thereby preventing the water ice from shaking. This is to prevent damage to the fish.

(Example) Figure 1 is a sectional view of the fish hold when a small amount is loaded.

FIG. 2 is a sectional view of the fish hold according to the present invention.

First, after throwing a small amount of fish into water ice, the air bag 2 in a folded state is thrown in from the fish hold opening 1. Next, air is sent into the air bag 2 through the air hose 4 to inflate the air bag 2.

Next, seawater is injected to fill the fish hold and close M5.

3 and 4 are perspective views showing the shape of the airbag.

As shown in Fig. 5, cooling piping 6 is often installed inside the side wall of the fish hold, and the airbag 2
If the airbag 2 is blocked, the cooling effect will deteriorate.
Consideration should be given to providing a certain amount of space. Further, on a surface without such restrictions, the airbag 2 should be pressed against the wall surface and the airbag 2 should be fixed.

The airbag shown in Figure 3 is the most basic form, but the airbag shown in Figure 4 is designed to reduce deflection in the longitudinal direction, and is intended to suppress deformation of the airbag. It is.

(Effects of the Invention) As described above, according to the present invention, shaking can be prevented with less equipment and a little effort, and fish can be transported without damaging them. All of the problems mentioned above (problems to be solved by the invention) such as the ability to save a large amount of ice compared to the previous method can be solved, and it can contribute to preventing a decline in fish prices and significantly reducing transportation costs.

Claims (1)

[Claims] When loading a small amount into a fish hold on a fresh fish carrier, an airbag with a volume slightly smaller than the remaining loading capacity of the fish hold is inflated in the fish hold and seawater is injected to fill the fish hold to prevent the fish from shaking.
