Description

SYSTEM FOR CHILLING AND CONDITIONING TEMPERATURE DRINKS

The subject of the invention is a system for cooling and maintaining the temperature of the beverage. We can include it in the field of catering and catering. It is intended for users who want to convert their drinks into an unforgettable experience. The system consists of a glass, part of which is a container with a refrigerant that keeps the optimal temperature of the drink and allows the user to enjoy for a long time with a nice cooled drink. A part of the system is also a liquid nitrogen dosing device which, according to the type of beverage, enables the appropriate dosage of liquid nitrogen and thus the appropriate cooling and tempering of the drink. The functionality of the system is taken into account, as it enables the cleaning of glasses in the dishwasher, and the refrigerant is environmentally friendly and health-friendly since it is not toxic to pleasure, irritating by inhalation, no corrosion in contact with the skin, it is not mutagenic, carcinogenic or otherwise harmful human health. The system allows the serving drink to not change the structure, color, odor and maintain concentration.

Well-known solutions in the field of beverage cooling exist, but they do not provide an integrated solution as proposed by the presented system according to the invention.

There are glasses and decanter sausages - containers already on the market, but they are primarily intended for decanting wines. The flasks are made of glass and are fixedly fixed in the middle of a glass or decanter. Their purpose is primarily ventilation of wine or beverages and are not intended to chill and preserve the temperature of the beverage, as there is air inside the flask and not a refrigerant.

For the purpose of cooling and maintaining the temperature of the beverage, there are various inputs on the market that are cooled before use, usually in the freezer, and if necessary, they are made into glasses in order to cool the drink in the glass. Such inserts are, for example, granite cubes or stainless steel cubes which are removed from the glass after use. The advantage over conventional ice cubes is that they only cool the drink without diluting it or changing its taste. For every further use, the containers must be cooled again in the freezer, which requires a certain amount of time and space. It is difficult to control the tempering of the different beverages according to the type of beverage, and in addition, these cartridges disturb the user when drinking, as they are freely movable in the glass. Lastly, the use of said containers is not aesthetical in the user's view, especially when the drink is a wine.

It is the object and object of the invention to enable the user to provide with one system the cooling and preservation of the beverage temperature, even in cases where it is necessary to prepare beverages that are suitably cooled according to the type of beverage for a greater number of guests. This is an example of banquets, weddings, social events with a higher number of guests, more than 50 guests at a time. The mobility of the system makes it easy to use at different locations and provides the recommended temperature for drinks when guests arrive, thus improving the personal experience of drinking beverages.

The invention solves the problems of cooling and maintaining the temperature of the beverage occurring in the serving of beverages served in advance. The system allows the serving drinks to maintain and maintain the optimum temperature according to the selected drink, and also provides a user aesthetic pleasure in drinking. The materials used and its implementation ensure the safe use of the system.

The invention will be described below and presented with an exemplary embodiment and pictures illustrating the advantages and functionality of the system.

Figure 1 is a system for cooling and maintaining a beverage temperature according to the invention

Figure 2 shows a graph showing the temperature dependence of the beverage temperature from the glass time that was tempered at room temperature.

The system for cooling and maintaining the temperature of the beverage represented in Figure 1 includes a glass 1 with a container 2 in which the refrigerant 3 and the liquid nitrogen dispenser 4 with the metering element 5 are located.

Glasses 1 may be of any shape and made of glass. The container 2 is fixed to the inner surface of the glass 1 in a manner known per se, so that the container 2 is inseparably connected to the glass 1 and forms part of the glass 1. The container 2 can be attached to the various parts of the inner surface of the glass 1, the part the inner surface of the glass 1 is defined such that the entire container 2 is preferably covered with a drink when it is poured into a jar and delivered to the user. In a preferred embodiment, the container 2 is fixedly fixed to the inner surface of the glass 1 in the middle of the glass 1.

Container 2 can be in the form of different bodies, for example in the form of a cube, a sphere, a pyramid, a cone, and the like. In the preferred embodiment, the container 2 is in the form of a cube. It is desirable that the dimensions, shape and attachment of the container 2 to the inner surface of the glass 1 be set so that the maximum surface of the container 2 is in contact with the beverage poured into the glass 1, since in this case optimal cooling and maintaining the temperature of the beverage in a glass 1. The dimension and shape of the container 2 is adapted to the dimension of the glass in each case 1. In a preferred embodiment, the dimension of the container 2 is adapted to the dimension of the glass 1 such that the top of the container 2 also denotes a unit of measurement or a quantity of beverage poured into a glass 1, for example 1 dl, 2 dl, 3 dl, ... liquid in a glass 1. The container 2 is preferably made of glass. In one embodiment, the glass 1 may be made in such a way that it is formed in the lower part by a double wall, which in this case represents the container 2 where the refrigerant 3 is filled.

Glasses 1 and container 2 can be made in different colors, paints and inscriptions.

Optionally, several containers 2 may be fixedly fixed to the inner surface of the glass 1.

The container 2 is filled with refrigerant 3, at least 70% of the volume of the container 2 being filled with refrigerant 3, in order to ensure adequate cooling and maintaining the temperature of the beverage in the glass 1. For the optimum operation of the system, it is assumed that the total volume container 2 filled with refrigerant 3.

The refrigerant 3, by which the container 2 is filled, is an agent capable of cooling and maintaining the temperature of the beverage. These are health-harmless compounds that are in the form of gels at room temperature, for example gelatin, agar, alginate, carrageenan and other compounds in the gel aggregate state or other digestible gels. Additionally, the refrigerant 3 may include compounds that prevent the formation and growth of bacteria and fungi and which are not dangerous to humans when ingested, for example ammonium hydrochloride, bicarbonate sodium, natural essential oils, for example, tea tree essential oil. The refrigerant 3 may include either only one gel, or a mixture of several gels in any ratio, or a mixture of gel or several gels with compounds which prevent the growth of bacteria and fungi, wherein the addition of the compound is from 0 to 3 wt. % based on gel. Particularly suitable refrigerant 3 is gelatine because of its elongation coefficient, as it prevents the breakdown of the container 2 when cooling, and also facilitates the filling of containers 2.

Oleic acid and water are not suitable as refrigerant 3 for the system described. Water is because due to the inadequate coefficient of expansion, the container 2 may be disintegrated during cooling, and oleic acid is mainly due to problems with filling the container 2. In a preferred embodiment, the refrigerant 3 is a mixture of industrial gelatin and ammonium chloride, the amount of ammonium chloride 1, 5% by weight based on the amount of industrial gelatin.

The system according to the invention further includes a liquid nitrogen dispenser 4 to cool the jar with a container in which the refrigerant is located before use.

From the dispenser 4, the liquid nitrogen from the cylinder through the closed system is fed into a glass 1. Liquid nitrogen immediately cools the glass 1 with the container 2 and the refrigerant 3. The dispenser 4 is carried out with the dosing element 5, where at the dose of the glass 1 touches the element for dosing 5 so that the glass 1 completely clogs the dosing element 5 with its edge. In this way, the unwanted leakage of liquid nitrogen on the sides is prevented, thereby permitting safe use of the dispenser 4. In the preferred embodiment, the dosing element 5 is a nozzle.

The amount of liquid nitrogen to be dosed in a glass 1 to achieve the desired effect and to prevent damage is between 5 and 50 ml, preferably between 5 and 20 ml, depending on the type of beverage, i.e. the serving temperature provided for a single drink. The amount of liquid nitrogen can be regulated via the built-in regulator.

The liquid nitrogen dispenser 4 can be implemented in several versions. In the basic version, the liquid nitrogen dispenser 4 is implemented with one button, it being assumed that each time, with one push of a button, approximately 20 ml of liquid nitrogen is dosed in a glass, independently of the type of beverage. If large quantities of liquid nitrogen need to be dosed, the key must be pressed repeatedly. In the second version, the liquid nitrogen dispenser 4 is implemented with several keys, each key having a predetermined amount of liquid nitrogen, which will be pressed into the glass 1 upon pressure, and the amount of liquid nitrogen is determined by the type of beverage, similar to that is also provided in the version of the dispenser 4, which has a refrigerator adapted to the storage of glasses on the lower part 1. A dispenser 4 is also provided without a refrigerator, which is placed on the table and is portable. In one embodiment, a manual nitrogen dispenser is also provided, e.g. Sprayer in the form of spray or hand-portable storage.

The invention will now be described with an exemplary embodiment.

Preparation of the refrigerant 50 g of gelatin is dissolved in 50 mL of D1 of water and heated to gelatin start to melt. Add 50 mL of ammonium chloride and boil to the most liquid and clear blends. The gelatin is dissolved under heating and mixed with a solution of ammonium chloride. In the process of preparation, the boiling point is not exceeded, thus preventing the formation of air bubbles, which in the next stage of manufacture will prevent optimum filling of the containers. The filled containers 3 are then filled with the refrigerant 3 thus prepared. The following are the measurements proving the functionality and practical applicability of the system for cooling and maintaining the temperature of the beverage.

The test was carried out on wine at room temperature. We checked every test with a parallel. Figure 2 shows a graph showing the variation in the temperature of the wine in various processed glasses depending on the time and which best describes the cooling properties of the system. Glasses of the same shapes were used, all of which were pre-tempered in a refrigerator at 3 ° C for 16 hours before further processing. The same amount of wine at room temperature was poured into all differently treated jars and then the time dependence of the wine temperature in the glass was measured.

Classic glass - measurements refer to a glass previously treated only by tempering in a refrigerator at 3 ° C for 16 hours. It is clear from the graph that the temperature of the beverage tempered at 20 ° C in an environment where room temperature is increasing in time.

No nitrogen with container - measurements refer to a glass containing a refrigerant container, which was previously treated only by tempering in a refrigerator at 3 ° C for 16 hours. Liquid nitrogen was not used. The results of the measurements show the effect of the refrigerant. The beverage maintains an initial temperature of 20 ° C in an environment where room temperature is up to 20 minutes.

Nitrogen without container - measurements refer to a glass without a container, which was cooled by 16 ° C for 16 hours after cooling in the refrigerator using a liquid nitrogen dispenser. Approximately 80 ml of liquid nitrogen was dosed in a pre-cooled jar. The graph shows that liquid nitrogen in the first phase effectively cools the drink effectively within three to four minutes, but the effect of holding the temperature of the beverage without the use of a refrigerant container is poor. With container and nitrogen - measurements refer to a glass where a system for maintaining and cooling the temperature of the beverage that is the subject of the patent application was used. To a pre-cooled glass with a container that was tempered in a refrigerator at 3 ° C for 16 hours, up to 50 ml of liquid nitrogen was dosed. The results of the measurements show that the served beverage was cooled after 5 minutes from the initial temperature of 20 ° C to 7 ° C and kept the temperature below 15 ° C for a further 13 minutes.

The results of the measurements confirm that the use of the system according to the invention ensures that the temperature of the beverage is maintained and maintained. The results presented in the graph confirm that an optimal temperature was achieved after 5 minutes, for example, white wines, which is 7 ° C lower than the initial temperature of 20 ° C, where the wine had room temperature before using the system.
