Technical Field

The utility model relates to the field of packaging, concretely relates to utilize frozen water mixture to preserve packaging structure of goods.

Background

The lower the temperature, i.e. the temperature at which the food is frozen, the more significant the effect of inhibiting the declared activity of the microorganisms, from a microbiological point of view, generally the biological zero (i.e. the temperature at which the microorganisms stop growing) of the microorganisms is 0 ℃, so that lowering the temperature below 0 ℃ greatly extends the shelf life of the fresh meat product. The meat product can ensure that the cell structure is not damaged under the condition of not freezing, the cells ensure the fresh and alive state, the temperature of water freezing in the muscle of the pig is lower than and close to-2 ℃, and the ice temperature of the pork requires that the central temperature of the pork is controlled within the temperature range of-2 ℃ to-0.5 ℃ for storage. High oxygen modified atmosphere (80% oxygen + 20% carbon dioxide) is used to make the meat have better muscle color. The ice temperature preservation technology is combined with the air conditioning technology, so that the meat has better freshness and longer shelf life, and the meat has better color sense.

However, the temperature range of the ice temperature is narrow, the difficulty of temperature control at-2 ℃ to 0.5 ℃ is high, and the ice temperature is easily influenced by refrigeration equipment, particularly the shelf temperature of goods is difficult to control, and the ice temperature is easily influenced by wide temperature fluctuation.

And secondly, a heat insulation plate is arranged below the ice water mixing layer, and the storage goods are placed above the heat insulation plate.

In the process of slowly freezing, the ice-water mixing layer floats upwards due to the fact that the weight of the ice is light, generally speaking, the ice is arranged above the ice-water mixing layer, liquid is arranged below the ice-water mixing layer, and the temperature of the liquid below the ice-water mixing layer is slightly lower, so that when goods are directly placed on the ice-water mixing layer, the goods are in direct contact with the ice-water mixing layer, the temperature of the goods is reduced too much, the quality of the goods is affected, and the temperature insulation plate is arranged below the ice-water mixing layer, and therefore the goods can be kept in a required temperature range.

Meanwhile, the upper end of the ice water mixing layer is of an ice crushing structure, and the volume of the upper end can expand in the icing process, so that the liner gap is arranged above the ice water mixing layer, the ice water mixing layer cannot be broken in the icing process, and the use efficiency is improved.

Specifically, the cooling structure comprises a heat-insulating layer sleeved outside the ice-water mixing layer and a low-temperature layer positioned between the ice-water mixing layer and the heat-insulating layer. The low-temperature layer is a refrigerating device.

The low-temperature layer can be used in various ways according to different conditions, for example, in a factory, the refrigerating device can be used for air conditioning refrigeration, and can also be of other structures, and in a transportation environment, the low-temperature layer can be of a small liquid refrigeration structure.

Compared with the prior art, the utility model, following advantage and beneficial effect have:

the utility model relates to an utilize frozen water mixture to preserve packaging structure of goods, this structure utilizes frozen water mixture to have constant temperature, and the nature that the temperature is irrelevant with the degree of icing, mixes the layer with the frozen water as the temperature buffer layer, not only can make the internal temperature of goods stable, can also make the goods keep in required narrower temperature interval simultaneously;

moreover, when the goods are kept in a narrow temperature range, the structure can be directly used for adjusting and controlling the ice water mixing layer, the adjustment is simple, the operation and the monitoring are more convenient, the use efficiency is increased, and the cost is saved.
