In view of the above, the present invention solves the above-mentioned conventional drawbacks. The main object of the present invention is to form the inside of the cold storage chamber into three-stage compartments with functionally functional sheet material, and the upper stage is iced. , A water-absorbing drainage sheet for accommodating seafood is laid in the middle stage with a heat-insulating moisture-permeable sheet interposed, and a liquid chamber is formed in the lower stage with the water-absorbing drainage sheet interposed.
In addition, the inside of the cold storage chamber is formed in three layers, and a heat insulating moisture permeable sheet is provided in the upper tier to accommodate fish and shellfish. The solid chamber is provided with a water-absorbing drainage sheet for accommodating ice in the upper portion, and a lower liquid chamber is formed on the back surface of the water-absorbing drainage sheet.
Therefore, according to the present invention, the seafood caught in the cold container and the ice can be separated and stored without direct contact, and all can be cooled evenly. Furthermore, there is no divisional cold storage container for seafood that does not damage the seafood and that can effectively use ice as a cooling source and that can penetrate the liquid portion and prevent discoloration, deformation, etc. as much as possible. It is to provide.

In order to achieve the above object, in the divided cold storage container for seafood according to the present invention, a heat insulating moisture permeable moisture forming a fixed chamber for storing ice in the upper stage using a functional partition sheet material in the cold storage chamber.

In addition, there is an effect that it is possible to solve the problem that there is no evaporation amount in the gas chamber in the case of a non-combustible cloth or sponge that absorbs water by capillary action inside the cold storage chamber as in the prior art. In the present application, by dividing the inside of the cold storage compartment into three stages, it is possible to reliably prevent damage and discoloration of seafood by ice, and cool air is lowered from the top, so that the internal heat exchange is good There is. Moreover, depending on the heat-insulating and moisture-permeable sheet on which ice is placed and accommodated, only the vapor is allowed to pass, and the dripping amount is allowed to flow into the liquid chamber without being retained in the gas chamber. Furthermore, depending on the water-absorbing drainage sheet in which the liquid chamber is provided in the lower part of the gas chamber on which the seafood is placed and stored, there is an effect that the drip moisture quickly passes through the gas chamber and flows down to the liquid chamber.
In addition, the inside of the cold storage chamber is formed in three stages, a gas chamber, a solid chamber, and a liquid chamber from the top, and seafood is stored in the upper gas chamber, and ice is placed and stored in the middle solid chamber. When the temperature of the fish and shellfish to be accommodated is + 4 ° C., the cooling is insulated by the heat-insulating and moisture-permeable sheet, and there is an effect that water vapor is surely dissipated to the fish and shellfish on the upper part and the freshness is maintained. Also, depending on the water-absorbing drainage sheet on which ice is placed and stored, the water content of the ice inside can easily flow down to the lower liquid chamber.

  According to the divided cold storage container for seafood configured as described above, the cold storage chamber is formed with a liquid chamber of a space for storing ice and liquid in the lower stage.
