Description

60378

The invention relates to a method for keeping fish fresh in a compartmentalized warehouse and for transporting and storing fresh fish in a vessel or other vehicle with a compartmentalized hold, which method uses lifting-resistant, tightly closed, tightly closed in which fish or fish, water and ice are placed. In the past, in the storage and transport of fish fresh, e.g. a method in which fish are placed, for example, in compartments in the hold of the ship with water and ice. The disadvantage of this method is the cleaning of the compartments, which has proved to be very difficult. However, this cleaning operation is quite important in the case of foodstuffs and is also a statutory measure and thus controlled by the authorities.

In the past, separate boxes have also been used in which fish or fish, water and ice are placed. The disadvantages of such a method are the high cost and also the difficulties encountered in cleaning.

Attempts have also been made in the art to place fish or fish, water and ice in flexible sacks, but this has become a problem with durability and keeping the sacks in place. The sacks have practically not withstood the stresses caused by the heeling of the ship, etc., or the full sacks have even fallen into the sea, due to the poor retention caused by the flexible structure.

The object of the invention is to eliminate the above-mentioned drawbacks and to provide a new and more practical method of storing and transporting fish.

The basic idea of the invention is to utilize water lifting, whereby the use of flexible sacks is possible.

More specifically, the method according to the invention is mainly characterized in that sacks filled with fish or fish, water and ice are placed partly in water-filled or simultaneously filled containers, whereby the surface of the water in the compartments rises to the top surface of the sacks.

The advantages of the method according to the invention are e.g. purity 10 and low operating costs. This is explained by the fact that the compartments in the hold of the ship can be treated with any suitable substance to destroy any bacterial strain and still the substance does not come into contact with fish. Operating costs are made small because there are e.g.

15 possible to use the so-called. large sacks consisting of a strong outer sack and a replaceable inner sack at a relatively low price. In addition, the method has the advantage that fish or fish, water and ice can be easily dispensed into sacks so that each sack contains e.g.

20 exactly the volume of transport boxes used for further processing, which reduces the processing costs.

The invention will now be examined in more detail with the aid of the accompanying drawing, in which two embodiments of the method according to the invention are shown by way of example.

Fig. 1 shows in principle an embodiment in which the sacks are arranged in one layer, Fig. 2 shows in principle (front wall 30 imagined removed) one tray from the side in an embodiment in which the sacks are arranged in two layers.

In Fig. 1, reference numeral 1 denotes compartments which are known per se placed in a warehouse or hold of a ship or the like (not shown in the figures). The trays can be equipped with suitable water supply and discharge means (not shown in the figure). According to the invention, the trays 1 are partially filled with water and cooled. Cooling can take place, for example, by adding ice to the water, but of course other methods can also be used. The surface of the water in the empty tray 5 is described by reference numeral 2.

Fish or fish, water and ice are placed in the method according to the invention, e.g. in big bags 3 that can withstand lifting when filled with the desired amount of fish or water, ice and fish. Such sacks usually consist of a strong outer sack and a replaceable inner sack. Of course, other suitable sacks can also be used within the scope of the invention.

Thus, together with the fish, water and ice can be placed in the sacks 3, if necessary, in order to keep the fish 15 fresh.

The dosing of fish or fish, water and ice into the sacks 3 can take place in such a way that the boxes used in the reprocessing, etc., draw the amount of material contained in one sack, thus facilitating the reprocessing.

In the method according to the invention, the sacks 3 are placed in the compartments 1 as shown in Fig. 1. When the sacks 3 are placed in the compartments, the surface of the water in the compartments rises to the top surface of the sack, the sacks in the compartments floating in the compartment.

The amount of water fed to the trays 1 naturally depends on the volume of the sacks 3. Thus, so much water is supplied that the water level after placing the sacks 3 in the compartment 1 rises above the upper surface of the sacks. This level 30 is indicated in Figure 1 by reference numeral 4.

The supply of water to the trays can take place before the sacks are placed in them, but especially on board it is advantageous to supply water at the same time as the sacks are placed in the trays due to the risk of overflow.

4 60378 The sacks 3 are suitably closed so that the sack remains tight after several lifts, but can still be opened if necessary.

Any small leaks that may occur in the sack will work with the cold water in the compartments to maintain freshness. Due to the pressure of the water in the trays, the slimy water in contact with the fish cannot flow out of the sacks due to minor leaks, which naturally makes it easier to clean the trays, as the trays only come into contact with clean water.

When placed in accordance with the invention, the sacks can withstand the stresses caused by the movement of the ship because they are supported on all sides by water and their retention is ensured by means of the walls of the compartments.

According to the invention, sacks 3 filled with fish or fish, ice and water can be placed in differently sized compartments 1, one or more, as required. The sacks can also be placed either in one or, alternatively, also in several layers, because the water then prevents the lower sack from breaking by the weight of the upper.

Figure 2 shows, by way of example, one tray 1 from the side in the case where the sacks 3 are arranged in two layers. In this case, of course, so much water must be introduced into the compartment that, with both layers in place, the surface of the water rises to the level of the upper surfaces of the upper sacks. Figure 2 shows only one sack from the upper layer for clarity. This water surface is shown in Figure 2 by reference numeral 4 '. The walls of the compartments 30 can be either vertical or suitably downwardly converging relative to each other.

According to the invention, the compartments are suitably dimensioned so that the sacks to be placed in one compartment, which are preferably always lifted by the entire amount (one or more) of one compartment at a time, substantially fill the compartment as shown in the figures, effectively preventing the walls from moving. In this case, however, it should be noted that, for example, in the compartment shown in Fig. 2, the sacks can of course also be raised in layers and also stored there in one layer if necessary. In this case, of course, the amount of water fed to the tray must be adjusted according to the number of sacks.

The above examples are, of course, not given in a limiting sense, but other solutions are also possible within the scope of the invention.
