• the apparatus has an innovative coupling assembly for the extraction of liquid CO 2 to spray the vessels, whose particularities will be described later.
• the field of application of the present invention is part of the technical sector of the industry dedicated to the manufacture of cooling or cooling devices and devices as well as the industry dedicated to the manufacture of parts for coupling elements and devices for gas extraction and / or liquids.
• said apparatus succinctly, consists of a housing that, internally, incorporates a connection fitting that connects an electrovalve to the hose where the gas coming from a bottle will enter, which is linked to an electronic, programmable digital plate or analogically, and coupled to a flow regulator, formed by a piece of machined brass that calibrates the exact flow of gas, which, in turn, is coupled to an extension piece with an inner jacket that connects with a second piece of extension, on which end the spray diffuser nozzle of cold is placed through whose holes the gas that is applied inside the vessels to be cooled emerges, said glasses must be placed on it, arranged on cup holders provided for that purpose in the Case.
• one of the main disadvantages of said apparatus is due to the fact that it is the vessel that is placed on the nozzle and the gas rises upwards, there is a risk of causing damage or injury, since CO 2 liquid is so cold it can burn if it comes into direct contact with the user's hands or face.
• the fact that the glass is placed face down on the spray nozzle prevents cooling elements contained in it, such as ice cubes, whose cooling with CO2, as is known, allows them to be stored for a longer time without melting. Circumstance especially noticeable in the hospitality and catering sectors to which the device is eminently focused.
• the apparatus in question such as that described in the patent cited in the previous background section, and which, as indicated above, is based on the use of liquid CO 2 sprayed from a nozzle in a glass or in another container to get it to cool quickly at a very low temperature (between -2O 0 C and -3O 0 C), it has, essentially, as functional elements, with a connection fitting, which connects an electro valve to a hose, where the gas from an external cylinder of C02, and conveniently provided, said hose for connection to the cylinder, of regulated pressure valve, purge valve and pressure gauge.
• said solenoid valve is linked to a programmable microchip that allows to regulate the impulses and pauses of gas output, while coupled to a flow regulator, with at least one extension piece, in which, at its once again, the diffuser spray nozzle is provided with holes through which the gas leaves to cool the vessel or container in question.
• the apparatus now proposed has the particularity of having a structural design by means of which, instead of placing the vessel on the spray nozzle, said vessel or container is arranged under it, receiving the gas spray from its top.
• the apparatus is configured from a bottom support base, essentially flat, on which is coupled, preferably on one of its sides, a hollow tubular body that extends in a vertical section and, at a certain height, is 180 ° curve incorporating at its distal end a bell that is arranged upside down, elevated at a certain distance on the above-mentioned base, said distance being the necessary one so that between said bell and the base a vessel or other vessel of dimensions more or more can be placed less conventional and fit under it to proceed to its cooling.
• the incorporation of some mechanism that allows to regulate the aforementioned distance between the bell and the base to achieve said adjustment of the container under the bell is contemplated, either by vertical displacement of the tubular body, and consequently of the bell, for example of telescopic type, or, by vertical displacement of the area of the base in which the container to be cooled is positioned, for example by means of a lifting platform.
• connection fitting which joins the solenoid valve to the hose through which the gas will enter, is coupled at the distal end of the tubular body and an extension of the hose runs through said tubular body to exit below the base and extend to the cylinder, while the solenoid valve, the microcontroller, the regulator, the extension and the spray nozzle, respectively connected to each other, they are oriented downwards and housed under the hood.
• the nozzle forms a more closed envelope to fit the edge upper of the glass or container to cool, favoring the circulation of the gas when bouncing on the inside of the container.
• This second bell protects the solenoid valve and the microcontroller from its direct contact with the gas.
• the regulator, extension and nozzle assembly also have a series of improvements that consist, first of all, of incorporating an insulating tube inside, specifically of teflonado type, so that the cold has the minimum loss of fridges, for which it covers the regulator and the extension inside, until reaching the height of the spray nozzle or diffuser outlet.
• the exit of the extension just after said Teflon tube has a narrowing that reduces the internal diameter of the outlet flow of said Teflon tube in half so that the gas acquires a greater degree of pressure and, having provided, after said narrowing, a conical widening that dissipates it in a range of about 38 °, so that the gas expands rapidly entering the outlet chamber of the spray nozzle which, more or less has said internal diameter.
• the spray nozzle in the stepometric orifices that it has for the spraying of the gas, and which are distributed in three levels of six holes, in addition to the central hole, a series of obstacles have been created in degrees, by means of the creation in its interior wall of inclined reliefs, so that the gas, instead of going directly towards the central hole, finds said obstacles and facilitates the flow exit regularly distributed through all its exit holes.
• the gas does not displace the vessel or pull it and, having less pressure accumulates more gas inside the vessel and, therefore, the cold is greater.
• the gas when the gas enters the inner hood, which is the one that covers the outlet nozzle and works vertically, it is advantageously achieved that the gas exits aerodynamically on the walls of the vessel circulating towards the opposite end and down the outer walls of it, both on one side and on the other.
• This snow has the advantage that it absorbs the water from the ice cubes creating a kind of artificial snow that covers them, and that by absorbing said moisture from the ice, its dissipation, as it has to be naturally, by evaporation of it It does not leave residues generating a white smoke that produces a striking effect, especially valued.
