Description

Unit cooler of packaged liquids.

Object of the invention

The present invention relates to a cooler of all types of packaged liquids, although its commercial projection preferential is aimed at cooling drinks intended for consumption by the public in hospitality establishments. It allows the establishment to maintain a wide variety of drinks like white wines, claret wines, beers, juices, cavas, champagne, etc. in ambient temperature conditions until moment they are requested by the client. By the present invention the beverage may be at the temperature desired by the consumer in a very short time, just a few minutes from which is requested by the client.

This equipment is expressly designed for the cooling of a single container or bottle on each occasion, obtaining an effective product, with small volume, light weight and therefore easily installable and transportable.

Background of the invention

The optimum consumption temperature of many Drinks certainly do not match the ambient temperature of storage of bottles or containers that contain them.

Hence it is usual in establishments of hospitality keep a number of bottles or containers of each mark inside cold stores until requested by the clients. The problem is that these cameras require some time considerable, several hours, to get the drink (especially white wines, champagnes and champagne) reach the desired consumption temperature. In case the bottles run out of a particular brand or type of drink, it is not possible to replenish new units at an optimal temperature in a reasonable time of Wait by the customer. This would force to use a space excessive in conventional cold stores if you want be prepared for any customer request, or to limit the available drinks menu, or finally to have to recognize before the client that the service cannot be provided that you asked for.

From the point of view of the establishments, it is interesting to save storage space in cameras Conventional refrigerators, save as for older investments in this type of cameras, as well as having a letter of drinks much wider than what you could have if you were limited by the capacity of its conventional cameras. From the point of view of the client, there is no doubt his preference for a establishment where there is no problem of being served Wine, cava or warm beer with food. For this it is necessary achieve ultra-fast or instant beverage cooling of so that the waiting time from its election by the client.

Currently there are means that allow virtually instant cooling of certain drinks at bulk, as is the case with draft beer, based on making circulate the drink through refrigerated coils, which allows a fast heat exchange

As for bottled drinks it is also known the use of a coolant, either by immersion of the bottle or container in it, either by placing it in a next position. In both cases, various systems of coolant mobilization, in theory to maintain some optimal thermal transmission conditions with the bottle or container concerned. In practice, however, there is no method truly effective in the market for cooling ultrafast of packaged drinks, or at least in the very short time span in which the present invention performs, based in a different system to achieve thermal exchange necessary.

The systems based on propellers or other electro-mechanical means, require the inclusion of a motor in the equipment, which drives an axis on which in turn the propellers that provide recirculation to the fluid are located. The shaft and the propellers are located in the tank where the fluid is located, but the engine must be placed outside that tank, being necessary to ensure the tightness of the tank necessarily drilled for this purpose. In addition to their lower efficiency, these systems are much more complex and expensive than those proposed by this invention and in the medium term give problems of lack of tightness and therefore leakage of coolant that affect the electronic equipment of the machine, as a result of natural wear which affects the seals with which attempts are made to waterproof the holes through which the
axes

Description of the invention

The invention relates to a cooler of packaged liquids, an apparatus that makes refrigeration possible almost immediately of the liquid contained in the bottle or container to the desired consumption temperature. It is based on the immersion of the bottle or container in a coolant with very low point of freezing, around -45ºC. Its novelty lies in the special characteristics of the reservoir containing the liquid cooler, from the equipment condenser location system space-saving refrigerator and in the exchange system thermal that allows cooling of the packaged beverage in a minimum time, much less than any other existing system nowadays.

The reservoir that contains the liquid refrigerant, condenser and evaporator of the equipment, is formed by a single piece of plastic material cylindrical, consisting of a polyethylene body inside hole. This hollow space defined by the outer walls is filling a layer of polyurethane foam or plastic material similar, which gives the piece mechanical resistance at the same time that good thermal insulation and consequent savings energetic. The set is also much lighter in weight and therefore more easily transportable than a conventional cooler with sheet metal structure and the materials used are not adhere, so that they can be easily separated for your subsequent recycling.

Inside this tank or cylindrical tank that we call exterior is another tank or cylinder called interior of smaller diameter, also filled with coolant, into which the basket containing the container with the drink is inserted. The refrigerating unit condenser, distributed in the form of a spiral or external coil, is located between both cylinders. The evaporator, distributed in the form of a spiral or internal coil, is housed inside the inner tank or cylinder, in the part closest to the basket with the packaged beverage.
gives.

From the refrigeration group, only the compressor is located outside both cylinders. The space saving is evident, taking into account that it is not necessary to install a fan that cools the condenser, since it is cooled by contact with the reservoir fluid itself. This refrigerating group is capable of supplying a temperature below -35ºC to the heat exchange liquid. The working temperature of the thermal transmission fluid must be kept below the indicated figure of
-35ºC, so that inside the inner cylindrical tank and in contact with said liquid there will be a thermostat that will control the operation of the compressor. This will only be put into operation if the temperature rises above the indicated working temperature.

As for the thermal transmission system, it based on the rotational movement of the basket in which it is deposited the bottle or container, using a pulley and belt system: In the top of the tank is installed a support that holds a trunk-cylindrical rod basket, covered by a waterproof and flexible membrane of material plastic or similar, in which the container or bottle that is inserted It contains the drink you want to cool. The top of this basket consists of a ring of plastic material (pulley # 1), supported on a circular bearing of the same diameter, joined by a belt with a pulley of smaller diameter (pulley nº 2), which can be drive by a motor that rotates at a speed of 1,500 revolutions per minute, which by means of a regulator provides the larger pulley (pulley # 1) a turning speed of between 40 and 80 revolutions per minute.

This movement of rotation of the basket makes the installation of a system of agitation and circulation of the coolant inside the tank unnecessary. The dynamic action generates a thermal exchange and therefore an optimal cooling and faster than any other system currently known, with a decrease in the temperature of the packaged beverage, between 8º and 10º per minute, depending on the characteristics and thickness of the
container.

At the top of the machine there is a digital reader indicating the temperature at each moment the coolant contained in the tank and a pilot of Compressor operation indication. Next to them stands a digital clock in which the user must select the time of rotation that you want the container to perform and that works as a countdown until it stops the rotation movement upon arrival to zero Finally, a regulator allows you to select the speed of rotation of the basket between several possible options, according to the type of beverage and container to be cooled

The dimensions of the set, considered even for cooling a bottle of the largest existing in the market as the so-called "magnum", not they would be greater than 40 cm. height, 40 cm. wide and 35 cm. in the background, which allows its easy location at the counter a hotel establishment within immediate reach of the waiter who Serves drinks and their easy mobility within different tables areas in a restaurant, or the different rooms of a hotel that wants to provide this service to its customers.
