Description

The invention relates to a device for storing refrigerated products, namely, double-wall thermoses, in which cooling of products and substances stored afterwards can be performed.

Some substances and products (for example, blood, transplanted organs, dairy and meat products, etc.) are stored without contact with the atmosphere or in non-gas atmosphere. In this case, a process is desirable in which the product is loaded into a container; the container is placed in a chamber in which it is sterilized with its inner tube or air is replaced with a gas, such as nitrogen, and sealed; then the container is placed in a refrigeration chamber, where the product is cooled to the required temperature, discharged from the refrigeration chamber and, if necessary, transported to the place of consumption.

Containers are known in which in order to reduce heat leakage, the body and the lid are double-walled I.

A disadvantage of the known container is that, due to the high thermal resistance of its walls, the process of cooling the product directly in the container would be very long. Therefore usually

Products that were previously cooled in other containers, such as open metal trays, are placed in the container. This creates a number of inconveniences (donor-related; labor costs required to transfer the product from tray B to the container, there is a danger of exposure to the product of high temperature if overloading occurs outside the refrigerating chamber, etc.).

The aim of the invention is to improve the cooling conditions of substances and solvates. not admitting a hgact with a vssa sroda in the process of cooling and subsequent storage:; en.

This is achieved by the fact that the interstitial cavities of the body and the container cores contain heat carrier (for example, freon-113) in the liquid and vapor phases, and the surfaces of the intrinsic wall of the Cornus facing the interwall cavity are covered with a capillary-porous material provided with protrusions towards the bottom of the container, the tips of which are located at a distance of about 0.5 mm from the inner surface of the bottom.

In this case, the amount of heat carrier in the interstice wall of the housing is chosen from the condition that during the storage of the product, the volume of the liquid phase of the heat carrier is

is equal to oyemu P0: p capillary-porous material.

FIG. Figure 1 shows the proposed container in the state of storage of products, a cross section; in fig. 2 - container in the state of cooling of the nodus, cross section.

The container for storing refrigerated i products has a cornus 2 and a cover o. Cornus and krynlka vnolnen; with double stsnkamn. The cavities between the walls of the stones are hermetic and contain a coolant in the well -1do and narov phases.

In the state of storage of products, when the ambient temperature is above the temperature B in the container, in the lid / cylinder 4 the coolant is collected in the lower part of the bed, and the rest of the nolost of the lid is occupied by the tarpaulin 5. This time in the cavity of the housing; the tenon-filler is assembled in the burrows of a cannll-nor-mat coating (; rial, provided with protrusions 7. The rest of the cavity of the housing is filled with a billet of a tenon carrier.

The operation of the container is carried out as follows.

Products that need to be cooled and then stored in a refrigerated state, but stored in a container and together with the container, are refrigerated. As the cooling of the inner walls of the container is higher than the outer, the tenon-filler, containing the holes of the cannel-noryte b cover, evaporates, and then condenses on the cold outer walls to form a condensate (Fig. 2). Through the 7 nods, the condensate is again retracted into capillary caption 6 by capillary action, then evaporated again, condensed on the outer walls, etc. Thus, the circulation circuit of the heat carrier in the cavity of the housing is closed. In the lid, the evaporating coolant condenses on the outer wall, forming a condensate film 9. Under the action of a gravitational force, the condensate flows downwards, but falls onto the bottom wall, reattaches, and so on. Thus, the lid of the tenon carrier circulation is closed in the lid.

With successive evaporation and condensation processes, the heat is continuously transferred from the inner to the outer walls of the chamber, due to which the product is cooled rapidly.

After cooling to a predetermined temperature, the container is removed from the refrigerating chamber. The storage then takes place at a temperature of the environment, which is above the temperature of the cooled product.

Under the ethnical conditions, the temperature of the outer CTCHOiK container becomes higher than that of the inner container, but therefore the B and U condensate lambs dry out and the liquid tenon beaker collects in the lid above the bottom wall and in the case in the holes of the cover 6, as shown in FIG. i. After this, the process of spraying and condensation in the interethin nolost stops because the liquid

the heat carrier does not mol. return to the external walls of the cavities (in the lid the return of condensate is prevented by force of gravity, and in the case - capillary sll holding tenonoenthel in burrows covered). Under these conditions, the heat transfer from the outside to the product in these conditions does not apply to the nylon layer of the tenonoentel in the cover of the corns. To prevent convective unrelieved tenla through

These nasrolling distances between the walls in the nots are sufficiently small (0.5-3 L1 m). Because of this, during storage the temperature of the cooled product is increased. It is read very slowly.

The proposed container is intended primarily for cooling and storing the next in it products and materials for which contact with

external front.

The advantages of the proposed container in this case are as follows: in the process of cooling and storage, the contact of the product with the external environment is excluded;

the stored product may be stored outside of the camera; The operation is to overload a chilled product.
