Description

Devices for selling various portion-sized juices, made in the form of a glass or similar vessel, provided with a drain cock in the lower part, are generally known. Attempts to adapt these devices for cooling juices at elevated outside air temperatures are also known, which helps the juices to preserve both their taste properties and to prevent the vitamins contained in juices from being spoiled. These attempts, however, turned out to be in fact unsuccessful due to the lack of a sufficient cooling effect and the impossibility of its regulation, as well as due to their inadequacy in protecting the juices from clogging up with their mixing. The proposed device is made in the form of a glass vessel and is equipped with a drain cock in the lower part, but in order to eliminate the above disadvantages, the device is equipped with a special reservoir inserted inside the draft vessel and used to place the cooled substance in it. In order to improve heat transfer, the cooling tank is provided with fins, or wings. In order to ensure the density of the coating, the cooling reservoir is fixed on the cover, which can be rotated. The drawing shows an exemplary form of the proposed device. FIG. 1 shows a tank with fins; FIG. 2 given another form of execution with a mixing screw surface. The device consists of a glass vessel /, to the bottom of which a glass drain valve 5 is attached by means of a tube 2. Through the upper neck of the vessel / is inserted inside its tank 5, which serves to place in it some coolant 6, for example, ice and so on. Experimental studies and theoretical calculations show that, due to the low thermal conductivity of a liquid, its cooling in the presence of only one heat transfer occurs very slowly. Similarly, the formation of convection currents inside coKOBi poured syrups, etc., is difficult, since the latter are usually very thick, and their internal viscosity is therefore high. According to the present invention, to increase heat transfer from the walls of the cooling tank to the liquid poured into the device, the walls of the tank 5 are provided with fins 9. These fins perform a dual role. They, first of all, increase the heat transfer surface and thus accelerate the cooling of juices poured into the device, which is very important in case of intensive tempering of juices. These ribs, secondly, serve to mix the juices and to regulate the degree of cooling.

The coolant insertion tank 5 in the upper part has a shackle 7 with a lug 8 for easy turning of the vessel in order to stir cool it with liquid.

The fins 9 can be made in a wide variety of forms, depending on the type of coolant, the nature of the fluid to be cooled, the degree of cooling desired, and similar factors. The simplest is the arrangement of the ribs in the form of straight strips 9 attached to the walls of the tank 5 (Fig. 1). The width of the strips may be almost equal to the width of the lumen between the reservoir 5 and the inner wall of the vessel 1, or it may already be depending on the above factors. These may be ribs in the form of continuous bands extending over the entire length of reservoir 5. In some cases, it may be more advantageous to make them not solid, but with cutouts or even to be made as separate ribs arranged in a row or in a checkerboard. order

In some cases, for particularly thick syrups and coKOBi, as well as for intensive cooling and stirring, which is especially important for precipitating juices, such as tomato, cooling and mixing ribs are proposed to be in the form of a helical surface 5 (Fig. 2), constant or variable screw pitch. This latter implementation form is the most effective, since with the help of it the most

intensive mixing of the cooled fluid and the movement of its layers. Indeed, by turning the flap 7 and the entire cooling tank 5 with the fins 9 in one direction or the other, it is possible to cause the layers of the cooled liquid to move up or down. To protect the coolant from dust and external air, tank 5 is covered with a lid 7 (Fig. 2).

To add to the vessel / juices or syrups without removing the lid 4, a hole U is made in it, closed by a swivel cap 11 (Fig. 1).

In winter, when it is not necessary to cool the juice, the cooling vessel is taken out of the tank, and the open surface of the tank is closed with a lid in order to prevent dust, etc., from entering the coolant.

The specified device can be mounted on the counter in several copies for the sale of various juices.

The proposed device can also be adapted for heating beverages, such as grog, mulled wine, etc., for which hot water is poured into the tank 5 or the like.

The subject matter of the invention.
