Description

Title: Gasification device

Technical area

The present invention relates to the field of beverage gasification devices.

Prior technique

[0002] Beverage carbonators (also known as soda machines) are machines for adding carbon dioxide (C02) to liquids in order to carbonate these liquids. For example, a beverage carbonator can be used to introduce bubbles of carbon dioxide into a bottle of liquid water to form a bottle of carbonated water.

[0003] Many beverage carbonating devices use carbon dioxide cartridges stored in compressed form for this purpose. A control valve allows the extraction of carbon dioxide from the cartridge and its injection into a bottle at a lower pressure in order to gasify the liquid contained in the bottle. An example of such a device is presented by the document W02020230115.

[0004] In this case, the user of this type of device is dependent on the quantity of carbon dioxide contained in the cartridge that he uses and must therefore monitor its level regularly, which is not always possible.

[0005] Furthermore, to refill an empty cartridge or buy a new cartridge, the user must move and/or order cartridges, thus resulting in polluting emissions. Indeed, the movement of the user and the logistics related to the transport of the cartridges are not neutral vis-à-vis the environment.

[0006] Beyond the transport logistics of these carbon dioxide cartridges, which are sometimes not very virtuous, the production of carbon dioxide to fill them can also be a source of polluting emissions, as can their recycling.

[0007] In addition, the carbon dioxide cartridges are expensive for the users who bear the cost of the cartridges and the cost of the refills as well as the cost of the fuel to exchange them.

[0008] The invention comes to improve this situation.

Presentation of the invention

[0009] One objective of the present application is therefore to propose a device for carbonating beverages without a carbon dioxide cartridge. [0010] In this respect, the invention proposes a device for carbonating a drink suitable for introducing gas into a drink contained in a container, characterized in that it comprises a carbon dioxide extraction system suitable for taking carbon dioxide from the ambient air and for compressing said carbon dioxide so as to inject it into the container at a pressure greater than a predetermined pressure threshold.

The beverage gasification device according to the invention thus uses the ambient air which surrounds it as a reservoir of carbon dioxide to be exploited in order to be injected into the liquid container. As a result, the beverage carbonating device no longer uses expensive carbon dioxide cartridges that generate polluting emissions. The user of the gasification device of the invention therefore no longer needs to go and buy these cartridges or bring them back to be recharged. The user is also no longer dependent on the quantity of carbon dioxide contained in his cartridge to be able to carbonate his drink and can use his device at any time while being respectful of the environment.

[0012] Optionally, the carbon dioxide extraction system comprises a carbon dioxide capture stage and a captured carbon dioxide compression stage, the carbon dioxide capture stage comprising a carbon dioxide adsorption element carbon dioxide adapted to adsorb carbon contained in the ambient air when the ambient air passes through the adsorption element, and a desorption element adapted to act on the adsorption element so that carbon dioxide is retained into the adsorption element is released from the adsorption element, the gasification device being further adapted to have two configurations including an adsorption configuration in which the adsorption element is in fluid communication with ambient air, and a desorption configuration in which the adsorption element is in fluid communication with the compression stage.

In embodiments, the carbon dioxide adsorption element includes a stack of electrodes, and the desorption element includes at least one electrical power source adapted to subject the stack of electrodes to a first voltage during a carbon dioxide adsorption phase and adapted to subject the stack of electrodes to a second voltage during a carbon dioxide desorption phase.

[0013] In embodiments, the adsorption element comprises a first adsorption bed and the desorption element comprises a first adapted heating element to heat the first adsorption bed during a carbon dioxide desorption phase.

[0014] In embodiments, the heating element comprises heating fins, and the adsorption material is placed in contact with said fins. [0015]

[0016] The capture stage allows the capture of carbon dioxide from the ambient air, in particular when the gasification device is in the adsorption configuration, that is to say when the adsorption element is in fluid communication with the ambient air. The desorption element allows the desorption of the carbon dioxide captured by the first adsorption bed. The compression stage allows the compression of the carbon dioxide desorbed from the adsorption element so as to inject it into the container at a pressure greater than the predetermined pressure threshold.

[0017] Optionally, the gasification device comprises an air supply circuit for the capture stage comprising a fan. The fan makes it possible to increase the flow of ambient air passing through the capture stage so that the first adsorption bed is charged more quickly with carbon dioxide.

[0018] Optionally, the air supply circuit of the capture stage further comprises a supply valve adapted to selectively authorize or block the circulation of air in said supply circuit. The supply valve is used to prevent the escape of carbon dioxide desorbed from the capture stage through the air supply circuit.

[0019] Optionally, the gasification device comprises a circuit for evacuating the air having passed through the adsorption element, the evacuation circuit comprising a system for adjusting the flow rate of evacuated air. The evacuated air flow adjustment system makes it possible both to evacuate the air discharged of its carbon dioxide by the first adsorption bed, to supply the capture stage with ambient air and to prevent the exit of the carbon dioxide desorbed from the capture stage through the air evacuation circuit. The evacuated air flow adjustment system can for example be a first exhaust valve.

[0020] Optionally, the capture stage comprises walls forming a removable cover adapted to be removed in the adsorption configuration so as to expose the adsorption element to ambient air.

[0021] Optionally, the gasification device comprises a housing containing the adsorption element and the evacuated air flow rate adjustment system is a movable wall of the housing. The exhaust air flow after passing through the adsorption element is regulated depending on a position of the movable wall. The mobile wall also makes it possible to admit ambient air into the capture stage.

[0022] Optionally, the gasification device comprises a housing, which comprises a first compartment housing the carbon dioxide compression stage and a second compartment in fluid communication with the first compartment, and the carbon dioxide capture stage. carbon is movable between a position located outside the housing and a position located in the second compartment. In this way, when the carbon dioxide capture stage is located outside the housing, the adsorption element is immersed in the ambient air and is rapidly charged with carbon dioxide as soon as the flow rate of ambient air passing through it is important.

[0023] Optionally, the compression stage comprises a carbon dioxide adsorption bed and a heating element adapted to heat the adsorption bed. The adsorption bed and the heating element of the compression stage allow thermal compression of the carbon dioxide desorbed from the first adsorption element.

[0024] Optionally, the compression stage comprises a pump adapted to inject carbon dioxide into the liquid container at a pressure greater than the predetermined pressure threshold.

[0025] Optionally, the compression stage comprises a pump adapted to reduce the pressure in the capture stage to a pressure below 500 mbar and to inject the carbon dioxide into the liquid container at a pressure above the threshold predetermined pressure. The pump allows both the desorption of the carbon dioxide adsorbed by the adsorption element by lowering the pressure in the capture chamber comprising the adsorption element and the compression of the carbon dioxide thus desorbed for its injection into the bottle. The pump may include a vacuum pump coupled to a compressor. In this case, the vacuum pump lowers the pressure in the capture chamber and recovers the carbon dioxide desorbed at low pressure in the compression stage. The compressor for its part makes it possible to compress the carbon dioxide desorbed at low pressure to a pressure greater than the predetermined pressure threshold to be injected into the container.

[0026] Optionally, the gasification device comprises a second evacuation valve adapted to selectively put the compression stage in fluid circulation with the ambient air, and an injection valve adapted to selectively put the compression stage in fluid communication with the container. The second evacuation valve allows evacuation of fluid from the compression stage to the ambient air, for example air pumped by the pump to lower the pressure in the capture stage. The third valve allows fluid communication between the compression stage and the container and therefore the injection of compressed carbon dioxide into the bottle.

[0027] Optionally, each adsorption bed comprises at least one material from activated carbon and zeolite. These materials have significant carbon dioxide capture properties.

[0028] Optionally, the predetermined pressure threshold is 2 bars. This allows the drink in the container to be carbonated.

[0029] The invention also relates to a process for carbonating beverages implemented by one of the devices presented in the present application, the process comprising: adsorption of carbon dioxide contained in the ambient air by the system of extraction of carbon dioxide, desorption of the adsorbed carbon dioxide in the carbon dioxide extraction system, compression of the desorbed carbon dioxide in the carbon dioxide extraction system to a pressure above the pressure threshold predetermined, - an injection of compressed carbon dioxide into the container.

The method according to the invention allows the gasification of a drink from carbon dioxide extracted from the ambient air. The carbonation of a beverage according to the method of the invention therefore uses carbon dioxide resources available in the ambient air reservoir so that the method is not restricted by an amount of carbon dioxide from a reservoir. of small volume such as the cartridges used in the prior art. It actually makes it possible to do away with these carbon dioxide cartridges, which are expensive for the user and emit pollutants in their design and in all the logistics that surround them, in particular for their transport and recycling.

[0031] Optionally, the adsorption is carried out by circulating air through an adsorption bed, and the desorption comprises the heating of said adsorption bed.

[0032] Optionally, the method comprises the activation of a fan to increase an ambient air flow to the adsorption bed. [0033] Optionally, when the gasification device comprises the housing comprising the first compartment housing the compression stage and the second compartment, the adsorption comprises placing the first adsorption bed in the position located outside of the housing, and the method further comprises moving the first getter bed into position in the second compartment prior to performing the desorption.

In this way, the adsorption is carried out when the capture stage is immersed in the ambient air so that the capture of carbon dioxide by the first adsorption bed is rapid. Furthermore, when the capture stage is positioned in the second compartment, the desorption can be carried out in the second compartment, which comprises very little or no circulation of ambient air so that the desorbed carbon dioxide is little or not evacuated from the second compartment by circulation of ambient air.

[0035] Optionally, when the gasification device comprises the housing comprising the first adsorption bed and the mobile wall, the adsorption is implemented when the mobile wall of the housing is open, the method comprises closing the mobile wall and carrying out the desorption step when the movable wall of the housing is closed.

In this configuration, when the movable wall of the housing is open, the flow of ambient air passing through the capture stage is high so that the carbon dioxide captured by the first adsorption bed increases rapidly. Conversely, when the movable wall closes, the circulation of ambient air in the capture stage is low or negligible so that the desorbed carbon dioxide is not or hardly evacuated from the gasification device by circulation of 'ambiant air. [0037] Optionally, when the gasification device comprises a compression stage comprising a second adsorption bed and a second heating element of said second adsorption bed, the compression comprises heating the second heating element so as to heat the second bed of adsorption.

[0038] Optionally, when the gasification device comprises a compression stage comprising a vacuum pump coupled to a compressor, the method comprises prior to the desorption: an extraction of the air from the capture stage to the ambient air by the vacuum pump, and in which the method comprises prior to the compression: an extraction of the desorbed carbon dioxide from the capture stage to the compression stage by the vacuum pump and, in which the compression comprises:

- actuation of the compressor on the carbon dioxide desorbed in the compression stage.

The extraction of the air from the capture stage to the ambient air by the vacuum pump makes it possible to reduce the pressure in the capture chamber to allow desorption of the carbon dioxide in the first bed. The extraction of the carbon dioxide desorbed from the capture stage to the compression stage by the vacuum pump makes it possible to recover the carbon dioxide desorbed by the first adsorption bed for compression. The actuation of the compressor on the carbon dioxide desorbed in the compression chamber makes it possible to compress the desorbed carbon dioxide to a threshold higher than the threshold determined so as to be able to be injected into the container.

The invention also presents a computer adapted to control gasification devices presented by the present disclosure in order to implement gasification methods detailed by the present disclosure and adapted to the device.

Description of embodiments

We will now describe, with reference to Figures 1a and 1d, a gasification device according to different embodiments.

The gasification device 1 is suitable for introducing gas into a drink contained in a container 7. It comprises a carbon dioxide extraction system 2 suitable for taking carbon dioxide from the ambient air and to compress said carbon dioxide so as to inject it into the container 7 at a pressure greater than a predetermined pressure threshold.

The pressure can for example be expressed in bars or in Pascals. In this case, one bar corresponds to 100,000 Pascals. The predetermined pressure threshold can thus be between 1 and 11 bars and can advantageously be greater than 2 bars.

The container 7 can for example be a bottle and the drink can for example be plain water so that the device makes it possible to switch from plain water to sparkling water after injection of carbon dioxide.

[0054] Ambient air is to be understood in this disclosure as air around the gasification device or passing through the gasification device and constituting a reservoir of natural carbon dioxide.

The carbon dioxide extraction system 2 comprises a carbon dioxide capture stage 3 and a carbon dioxide compression stage 4, which are shown in dotted lines in the figures.

The capture stage and the compression stage can for example be included in a housing of the gasification device 1a. The housing can for example be made of metallic material or of plastic material. When the housing is made of plastic material, it can for example be made by injection molding, by example by using an injection molding machine. The housing is considered hermetic so that these walls do not allow ambient air to pass inside the gasification device except at certain places in fluid communication with the capture and compression stages. [0057] In particular, the capture stage and the compression stage are considered hermetic to the ambient air outside the gasification device except when the present disclosure specifies the contrary. As such, the capture stage and the compression stage comprise walls. Some of their walls can for example be common with certain walls of the housing or common between the floors. In the embodiment illustrated in Figure 1a, the upper wall of the capture stage 3 is common with the lower wall of the compression stage 4. The configuration illustrated in Figure 1a has a capture stage located below a compression stage. The size of the gasification device is therefore reduced on a horizontal plane. In other embodiments, the capture stage and the compression stage can also be arranged on a horizontal plane so that a wall common to the capture stage and the compression stage can be a side wall of the capture stage (corresponding to the opposite side wall of the compression stage). The bulk of the gasification device is therefore reduced on a vertical plane.

The capture stage is adapted to capture carbon dioxide from the ambient air by adsorption, and comprises in this respect an adsorption element 31, 311. The capture stage further comprises an element desorption 32, 321 adapted to act on the adsorption element 31, 311 so that carbon dioxide retained in the adsorption element is released out of the adsorption element.

In one embodiment, the adsorption element comprises a first adsorption bed 31, in particular shown in Figures 1a to 1d. In another embodiment, the adsorption element comprises a stack of electrodes 311. Such a stack of electrodes 311 is represented in particular in FIG. 1e. In any event, the adsorption element must at least comprise an anode and a cathode thus constituting a layer of the stack of electrodes 311 which may comprise several of which three are shown in FIG. 1e.

[0062] An adsorption bed should be understood in the present disclosure as a porous structure comprising a carbon dioxide adsorbent material on all or part of its surfaces. A carbon dioxide adsorbent material means a material exhibiting properties of carbon dioxide capture or storage on its surfaces, the carbon dioxide coming from fluids passing through the material. A carbon dioxide adsorbing material may, for example, comprise one of activated carbon and zeolite, which exhibit significant carbon dioxide adsorbing properties. An adsorption bed can for example be of substantially cylindrical or parallelepipedal shape. The cylindrical shape allows a better distributed adsorption of carbon dioxide on the surfaces of the adsorption bed comprising the adsorbent material. The parallelepiped shape allows for easier placement or replacement of the getter bed in the housing. The adsorption bed 31 may for example comprise a carbon dioxide adsorbent material enclosed in a mesh such as a metal mesh, for example a stainless steel mesh making it possible to contain the adsorbent material. The openings of the mesh are sized so that the adsorbent material cannot pass through it. The stack of electrodes 311 makes it possible to adsorb carbon dioxide on its surfaces, in particular when it is subjected to a first voltage.

[0065] When the capture stage comprises the first adsorption bed 31, the capture stage 3 is adapted to implement adsorption/desorption cycles of carbon dioxide by temperature inversion, also known as acronym TSA (Temperature Swing Adsorption). In some embodiments, the capture stage is suitable for implementing carbon dioxide adsorption/desorption cycles by temperature and pressure inversion (known by the acronym PTSA for Pressure Temperature Swing Adsorption).

Referring to Figure 3, there is shown the storage capacity of a carbon dioxide adsorption bed depending on the temperature and the partial pressure of carbon dioxide. The partial pressure of a fluid corresponds to the pressure exerted by this fluid in a volume comprising a mixture of fluids if this fluid occupied this same volume alone at the temperature of the mixture. As seen in the figure, the adsorption capacity of a material decreases when the temperature increases, and when the partial pressure decreases. Accordingly, temperature inversion adsorption includes the adsorption of carbon dioxide at a given temperature, for example room temperature, and the implementation of a temperature rise to cause desorption of the adsorbed carbon dioxide. Adsorption by temperature and pressure inversion further comprises the reduction of the ambient pressure making it possible to increase the phenomenon of desorption. Thus, when the capture stage comprises the first adsorption bed 31, the desorption element adapted to act on the first adsorption bed 31 comprises a first heating element 32 adapted to heat the first adsorption bed. adsorption 31. The heating of the first adsorption bed 31 by the first heating element 32 allows the desorption of the carbon dioxide contained in the first adsorption bed. The first heating element can for example comprise heating resistors. They can for example be arranged at several places in contact with the first adsorption bed to distribute the heating as evenly as possible on the first adsorption bed according to its geometry. In some embodiments, the first heating element is a positive temperature coefficient heater (known by the English name positive temperature coefficient heater). A positive temperature coefficient heater may include heating resistors arranged on positive temperature coefficient heating fins. The adsorbent material of the first adsorption bed can thus be arranged on these fins so that the heating resistors diffuse the heating directly onto the adsorbent material. Thus, the heating element and more specifically the heating resistors are placed directly in contact with the adsorbent material. In one embodiment, the adsorbent material is disposed on the fins comprising the heating resistors and these fins are enclosed in the metal mesh so that the adsorbent material disposed on the fins can be retained near the fins. Since the heating resistors are in direct contact with the adsorbent material, the energy required to bring the adsorbent material to the desired temperature for desorption is reduced.

The first heating element 32 can be adapted to be heated to a temperature above 90° C. and preferably to a temperature above HO'C. The first heating element 32 can be adapted to heat the first adsorption bed to a temperature above 80°O and preferably above 100°O, for example when the gasification device is in a desorption phase.

[0070] In the embodiments where the capture stage comprises the stack of electrodes 311, the desorption element comprises an electrical power source, for example a battery 321 adapted to supply the electrodes at a first voltage during of an electrode adsorption phase and at a second voltage during an electrode desorption phase. In this case, the carbon dioxide is adsorbed on the surface of the electrodes when they are subjected to a first voltage then it is desorbed from this surface when these electrodes are subjected to a second voltage, the second voltage being different from the first tension. In some embodiments, the capture stage 3 is adapted to be able to adopt a first so-called adsorption configuration in which the adsorption element is in fluid communication with the ambient air and can thus put implements a phase of adsorption of the carbon dioxide contained in the ambient air, and a second so-called desorption configuration in which, for the implementation of a desorption phase, the capture stage is in fluid communication with the compression stage.

[0072] In this respect, in some embodiments, the capture stage 3 is in fluid communication with the ambient air via an air supply circuit 5. A wall of the capture stage can therefore comprise a supply opening allowing passage of ambient air from the air supply circuit to the capture stage.

In this case, the ambient air passes through the air supply circuit 5 thus leading to the capture stage 3 which allows fluid communication between the adsorption element and the ambient air. In this way, when the device is in the first adsorption configuration, ambient air is brought by the air supply circuit 5 into the capture stage 3 and passes through the adsorption element which adsorbs the carbon dioxide in ambient air.

The air supply circuit can thus comprise a fan 51 so as to increase the ambient air flow passing through the first adsorption bed, which makes it possible to reduce the adsorption time allowing the accumulation of carbon dioxide. carbon through the first adsorption bed.

In embodiments and in particular that shown in Figure 1a, the air supply circuit of the capture stage may further comprise a supply valve 52 to selectively allow or block the flow of air in said power circuit.

The capture stage 3 is also in fluid communication with the ambient air via an air evacuation circuit 6. In this way, the ambient air having passed through the first adsorption bed is evacuated from the capture stage by the evacuation circuit. A wall of the capture stage can therefore comprise an exhaust opening allowing the air to pass from the capture stage to the ambient air.

[0077] The air evacuation circuit may comprise an exhaust air flow adjustment system so as to regulate the flow of air evacuated from the capture chamber, in order to allow the circulation of a flow of air. important air through the first adsorption bed in adsorption phases, and to prevent the circulation of an air flow through the air evacuation circuit in desorption phases to be able to direct the desorbed carbon dioxide to the compression stage.

[0078] In embodiments, such as for example the embodiments represented in FIGS. 1a, 1c and 1e, the air flow adjustment system may comprise a first evacuation valve 62 adapted to selectively authorize or prohibit air circulation in the exhaust circuit. Alternatively, as is the case of the example shown in Figure 1 d, the air flow adjustment system may include a second movable wall 63 that can adopt a first open configuration in which the flow of air evacuated is maximum, and a second closed configuration in which the evacuated air flow is zero.

[0079] In embodiments in particular that represented in FIG. 1a, by operating the evacuated air flow adjustment system together with the supply valve 52, it is thus possible to selectively isolate the adsorption element from the ambient air in particular for desorption phases, or to put it in fluid communication with the ambient air according to a more or less high flow rate for adsorption phases.

According to another embodiment shown in Figure 1b, the gasification device may comprise a housing comprising a compartment isolated from the ambient air, and the capture stage 3 may be movable between a first position, corresponding to the adsorption configuration, in which it is outside the housing and placed directly in contact with the ambient air, and a second position, corresponding to the desorption configuration, in which it is placed in the compartment isolated from the ambient air , this compartment being moreover in fluid communication with the compression stage 4. In this case, however, a fan 51 can also be provided to increase the air flow on the adsorption element when it is outside the lodging.

The capture stage can be positioned outside the housing in the adsorption configuration by a movement of a first movable wall 33 with which it is integral. The first movable wall 33 can be slidable and cause the capture stage to slide outside the housing like a drawer. The first movable wall 33 can also be rotatable and bring the capture stage to a position outside the housing by rotation.

In another embodiment not shown, the capture stage comprises walls forming a removable cover adapted to be removed in an adsorption configuration. Thus, when the removable cover is removed, the adsorption element of the capture stage is bathed in ambient air. In examples, the adsorption element can be mechanically attached to a specific wall of the capture stage 3 and the rest of the walls of the capture stage form the removable cover so that these walls can be detached from the specific wall of the capture stage 3 thereby exposing the adsorption element to ambient air. The gasification device thus carries out, in the first adsorption configuration, an adsorption of the carbon dioxide contained in the ambient air by the adsorption element by a circulation of ambient air passing through the element of 'adsorption.

In embodiments and in particular those shown in Figure 1a, 1c, 1d and 1e, the circulation of ambient air is implemented in the housing and corresponds to the ambient air from the supply circuit of air 5 (including or not the fan 51) passing through the adsorption element 31 before being evacuated from the capture stage by the air evacuation circuit 6.

[0085] In other embodiments, the air circulation is implemented at a position outside the housing and corresponds to the ambient air passing through the adsorption element from all sides due to its position outside the housing. lodging. In a variant represented in FIG. 1b, the air circulation also includes the ambient air passing through the supply circuit 5 driven by the fan 51 and leading to the adsorption element located in the position outside the housing.

In other examples, the air circulation is implemented by removing the removable cover of the capture stage so that the adsorption element is bathed in ambient air.

The compression stage 4 is suitable for compressing the desorbed carbon dioxide from the first adsorption bed and for injecting it into the container when the pressure of carbon dioxide in the compression stage is greater than the pressure predetermined.

[0088] In embodiments comprising the first adsorption bed 31, examples of which are illustrated in FIGS. 1a and 1b, the compression stage 4 comprises a pump 41 adapted on the one hand to reduce the pressure in the capture stage 3 before implementing the desorption, and on the other hand to compress the desorbed carbon dioxide in order to inject it into the liquid container 7 at a pressure above the predetermined pressure threshold.

The pump may comprise a vacuum pump adapted to reduce the pressure in the capture stage 3, for example to a pressure below 600 mbar and preferably below 200 mbar, and adapted to transfer the carbon dioxide desorbed from the capture stage to the compression stage. The vacuum pump can be coupled to a compressor suitable for compressing the carbon dioxide in the compression stage at a pressure above the predetermined pressure threshold. In these embodiments, the pump of the compression stage 4 also contributes to improving the desorption capacities of the capture stage by reducing the pressure of the capture stage during the implementation of the desorption.

[0091] In embodiments where the capture stage comprises the stack of electrodes 311, the compression stage 4 comprises a pump 41 adapted to compress the desorbed carbon dioxide in order to inject it into the liquid container. 7 at the pressure above the predetermined pressure threshold. Pump 41 acts as a compressor. In this embodiment, the carbon dioxide can be desorbed at ambient pressure in the capture stage by energizing the electrodes at the first voltage by the action of the electrical power source 321. Thus, the pump 41 of the compression stage is of reduced cost since it may not be suitable for reducing the pressure in the capture stage 3.

In other embodiments shown in particular in FIGS. 1c, 1d and 1e, the compression stage 4 comprises a second adsorption bed 45 and a second heating element 46 adapted to heat the second adsorption bed. adsorption 45. The compression of the desorbed carbon dioxide in this exemplary embodiment is thermal compression.

The second adsorption bed 45 and the second heating element 46 can be respectively similar to the first adsorption bed 31 and to the first heating element 32. This facilitates maintenance of the gasification device in the event of a fault on the one of these elements so that the user can simply replace a getter bed-heater assembly that is adaptable to the capture stage and to the compression stage.

[0094] The second heating element 46 can be adapted to be heated to a temperature greater than 90° C. and preferably to a temperature greater than 110° C. and it can further be adapted to heat the second adsorption bed to a temperature above 80° C. and preferably above 100° C., for example when the gasification device is in a compression phase.

[0095] The gasification device can also comprise a second evacuation valve 42 adapted to selectively authorize or prohibit a circulation of fluid between the compression stage 4 and the ambient air. In some embodiments, this allows the pump to expel the air included in the capture stage 3 to the ambient air to lower the pressure of the capture stage. In other embodiments, this makes it possible to expel the air laden with carbon dioxide from the capture stage 3 after the latter has passed through the second adsorption bed 45.

The gasification device can also comprise an injection valve 43 adapted to selectively place the compression stage in fluid communication with the container 7 in order to be able to inject carbon dioxide into the container. The gasification device is for example connected to the container by an injection conduit, which is open or closed depending on the position of the injection valve.

The gasification device can also comprise a stage valve 44 adapted to selectively authorize or prohibit fluid circulation between the capture stage and the compression stage. In embodiments and in particular those represented in FIG. 1a and 1b, the pump 41 can replace the stage valve 44 and can authorize or block the communication of fluid between the capture stage and the compression stage. The gasification device 1 can further comprise a computer, for example a processor, a controller or a microcontroller suitable for controlling the operation of the gasification device so as to successively implement adsorption steps and desorption. In particular, the computer can be configured to control the operation of elements such as the fan, the first heating element or the electrical power source of the capture stage, the various valves, the exhaust air adjustment system, the elements forming the compression stage (the pump, the compressor or the heating elements of the second adsorption bed) in order to be able to capture and inject the carbon dioxide at a pressure above the predetermined pressure threshold. A method 100 for carbonating a beverage presented in FIG. 2 and implemented by means of one of the devices presented by the present disclosure can thus comprise an adsorption 110 of carbon dioxide contained in the ambient air by the carbon dioxide extraction system. The adsorption can be carried out by the first adsorption bed 31 or by the stack of electrodes 311 subjected to a first voltage by the action of the electric power source and can comprise the action of valves, the setting fan route and exhaust airflow system opening.

[0100] The gasification process 100 can also comprise a desorption 120 of the carbon dioxide adsorbed in the carbon dioxide extraction system. The desorption can be carried out by heating the first adsorption bed by the first heating element or by subjecting the stack of electrodes 311 to a second voltage by the action of the electrical power source and may include the action of valves, the closing of the exhaust air flow control system, the starting or stopping of the fan and the actuation of the pump (particularly the vacuum pump).

[0101] The process 100 for carbonating beverages may further comprise compression 130 in the carbon dioxide extraction system at a pressure above the predetermined pressure threshold. The compression can include the actuation of the pump (and in particular of the compressor) or the heating of the second heating element allowing the heating of the second adsorption bed and the action of valves. Finally, the method 100 can also include an injection 140 of the compressed carbon dioxide into the container 7. The injection can be performed by opening the injection valve, for example via the injection pipe.

Referring to Figure 1a, there is shown an embodiment of the gasification device 1a described above. In this example, the gasification device comprises a housing comprising two superposed compartments, a first compartment storing the capture stage and the other compartment storing the compression stage.

[0104] The capture stage is connected to the ambient air by an air supply circuit 5 comprising an inlet valve 52 and by an air exhaust circuit 6 comprising a first exhaust valve 62. The compression stage comprises a pump 41 connected to the ambient air by a second evacuation valve 42 and has a pipe for injecting carbon dioxide into the container by an injection valve 43.

In this exemplary embodiment, the computer is suitable for controlling the implementation, by the gasification device, of the following steps. During an adsorption phase, the fan 51 of the air supply circuit is started, the inlet valve 52 and the first outlet valve 62 are open. The second evacuation valve 42 and the injection valve 43 are closed. Thus air flows through the adsorption element 31 at room temperature and carbon dioxide is adsorbed by the adsorption element 31. The pump 41 can block the fluid communication between the capture stage and the compression stage during the adsorption phase.

[0107] Then, the fan 51 is stopped, the inlet valve 52 and the first outlet valve 62 are closed to isolate the capture stage from fluid communication other than that with the compression stage via the bias of the pump allowing this communication. The second evacuation valve 42 is open. When the adsorption element comprises the adsorption bed 31, the pump is actuated to extract the air contained in the capture stage and thus reduce the pressure in the capture stage to improve the desorption phase. When the pressure in the capture stage is lower than a predetermined desorption pressure threshold, thus facilitating desorption, the pump 41 is stopped and the second evacuation valve 42 is closed so that the housing comprising the capture and compression is airtight. The predetermined desorption pressure threshold is advantageously less than 600 mbar and preferably less than 200 mbar. When the adsorption element comprises the stack of electrodes 311, the pump 41 does not necessarily implement this extraction of air from the capture stage.

The desorption element 32 of the adsorption element 31 is activated. Thus, when the desorption element comprises the first heating element 32 and the adsorption element comprises the adsorption bed 31, the first heating element is activated until the temperature of the adsorption element reaches a threshold temperature, for example IOO′Ό. When the desorption element comprises the electric power source and the adsorption element comprises the electrode stack 311, the electric power source is activated to power the electrode stack 311 at the second voltage. When the threshold temperature is reached or when the second voltage is reached, the pump 41 pumps the desorbed carbon dioxide from the capture stage to the compression stage (and therefore allows fluid communication between the capture stage and the compression stage). In particular, the pump 41 pumps a mass of carbon dioxide greater than a predetermined mass threshold from the capture stage to the compression stage. The predetermined mass threshold can for example be between 2 grams and 10 grams and advantageously correspond to 4 grams. Once the pump is deactivated, the first heating element 32 can also be deactivated.

[0110] Insofar as the pump 41 pumps carbon dioxide from the capture stage to the compression stage and the second evacuation valve 42 and the injection valve 43 are closed, the carbon dioxide desorbed in the compression stage is blocked in the compression stage until the injection valve 43 opens.

The desorbed carbon dioxide is therefore compressed to a pressure greater than the determined pressure threshold and when the pressure is greater than the predetermined pressure threshold, the injection valve 43 is opened to put the pump in fluid communication with the liquid container so that the compressed carbon dioxide is injected into the bottle. [0112] In embodiments, the desorbed carbon dioxide pumped from the capture stage to the compression stage can be compressed and gradually injected into the container. That is to say, a first mass of carbon dioxide can be pumped from the capture stage to the compression stage. The pumped carbon dioxide is then compressed by the compressor and then injected through the opening of the injection valve 43. The injection valve 43 is then closed while a second mass of carbon dioxide is pumped into the stage. compression, which is also compressed by the compressor then injected through the opening of the injection valve 43 and so on until the mass pumped from the capture stage to the compression stage is greater than the predetermined mass threshold. These embodiments make it possible to reduce the bulk of the gasification device since the volume of the compression stage can be small since the carbon dioxide is compressed and injected as it goes.

In other embodiments, it is envisaged to collect all of the mass of carbon dioxide to be injected into the container at once and then to compress it before injecting it. This mass of carbon dioxide can therefore be pumped from the capture stage to the compression stage. In which case, when the mass of carbon dioxide in the compression stage exceeds the predetermined mass threshold, the pump 41 is deactivated, the mass of carbon dioxide is compressed by the compressor to the pressure greater than the predetermined pressure threshold of so as to be injected into the container, for example by opening the injection valve 43. This allows in particular a reduced stress on the compressor in order to increase its longevity.

Referring to Figure 1b, there is shown another embodiment of a gasification device 1b, which differs from the previous example in that the adsorption element is movable between an adsorption position 3a located outside the housing of the gasification device, and a desorption position 3b in which the capture stage is located in a second compartment of the housing isolated from the ambient air, but in fluid communication with the stage compression.

In particular, when the capture stage 31 is positioned in its desorption position 3a outside the housing, the adsorption element 31 is in direct communication with the ambient air.

The capture stage 3 can for example comprise a first movable wall 33 of the housing secured to the adsorption element 31 allowing the capture stage to be taken out of the second compartment to position it in the outer position 3a. In FIG. 1b illustrated, the first mobile wall 33 of the housing corresponds to the upper wall of the second compartment but it may correspond to another wall depending on the configuration of the gasification device.

The first movable wall 33 may include gripping means, for example a handle (not shown), allowing a user to remove the capture stage from the second compartment to position it in the external adsorption position 3a.

[0119] Furthermore, the first movable wall 33 of the housing can be slidable like a drawer or can be rotated about an axis like a door so that the capture stage can be positioned outside the first compartment in direct contact with the outside air by sliding or rotating the first movable wall 63. In these embodiments, the user can for example move the capture stage by the means grip or a motor can drive sliding means or means of rotation of the first movable wall 33 to move the capture stage to the position outside the second compartment.

The gasification device comprises an air supply circuit 5 comprising a fan 51 to increase the flow of ambient air passing through the adsorption element 31 when the latter is in its adsorption configuration at the exterior of the housing, so as to accelerate the adsorption phase. Furthermore, when the capture stage is returned to its desorption position 3b in the second compartment, the first movable wall 33 is adapted to cooperate hermetically with the rest of the compartment housing the capture stage in the desorption position. so that the second compartment is isolated from any fluid communication except that with the first compartment comprising the compression stage for desorption.

[0122] As soon as the desorption is carried out in the second compartment and when the desorption element comprises the first heating element 32, this first heating element 32 can be arranged so as to heat the internal walls of the second compartment in contact with the first adsorption bed 31 as shown in FIG. 1b. The first heating element 32, in this embodiment, may not be attached to the first getter bed but to the second compartment. This makes it possible in particular to preserve it from potential damage caused by the movements of the capture stage between the adsorption position 30a and the desorption position 30b. The first heating element is therefore advantageously located on one or more walls other than the first movable wall 33. Heating resistors can thus line one or more walls of the second compartment. The compression stage 4 is located in the first compartment in fluid communication with the second compartment. In the same way as for the embodiment represented in FIG. 1a, the compression stage comprises a pump 41, for example a vacuum pump coupled to a compressor.

[0123] The gasification device 1b also comprises a second evacuation valve 42 for selectively putting the compression stage in fluid communication with the air and an injection valve 43 for selectively putting the compression stage in fluid communication fluid with a container 7, for example via an injection conduit.

In this exemplary embodiment, the computer is suitable for controlling the implementation, by the gasification device, of the following steps.

[0125] During an adsorption phase, the capture stage is positioned at the adsorption position 3a outside the housing, for example by the action of a user using means for gripping the mobile wall 33 or by the action of a motor as mentioned above.

In the case where the capture stage in the adsorption position 3a is supplied by an air supply circuit 5 comprising a fan, the fan is started. Thus the air circulates through the adsorption element 31 at room temperature and carbon dioxide is adsorbed by the adsorption element 31.

[0127] After the adsorption phase, the fan 51, if present, is stopped, and the capture stage is moved to be positioned in its desorption position 3b in the second compartment by the action of a user or by the action of a motor depending on the variant of gasification device 1b envisaged. The rest of the steps that the computer is adapted to control in this embodiment are the same as for the embodiment presented in FIG. 1a.

In particular, the second evacuation valve 42 is open and the pump can be actuated to extract the air contained in the capture stage depending on the embodiment envisaged. When the pressure in the capture stage is lower than the predetermined desorption pressure threshold, the pump 41 is stopped and the second evacuation valve 42 is closed so that the housing is hermetic to the ambient air.

The desorption element 32 of the adsorption element 31 is activated. In the embodiment comprising the first heating element 32, the latter is activated until the temperature of the adsorption bed 31 reaches a threshold temperature, for example 100°C. In the embodiment including the source of electrical energy, the source of electrical energy is activated to supply the stack of electrodes 311 at the second voltage. When the threshold temperature is reached or when the second voltage is reached depending on the embodiment implemented, the pump 41 pumps the desorbed carbon dioxide from the capture stage to the compression stage. The pump 41 pumps a mass of carbon dioxide greater than the predetermined mass threshold from the capture stage to the compression stage. Once the pump is deactivated, the desorption element 32 can also be deactivated.

[0131] Insofar as the pump 41 pumps carbon dioxide from the capture stage to the compression stage and the second evacuation valve 42 and the injection valve 43 are closed, the carbon dioxide desorbed in the compression stage is blocked in the compression stage (in the first compartment) until the injection valve 43 is opened.

The desorbed carbon dioxide is therefore compressed to a pressure greater than the determined pressure threshold and when the pressure is greater than the predetermined pressure threshold, the injection valve 43 is opened to put the pump in fluid communication with the liquid container so that the compressed carbon dioxide is injected into the bottle.

Referring to Figure 1c is presented a third embodiment of gasification device 1c. This third embodiment differs from the first embodiment illustrated in FIG. 1a in that the compression stage is different, that the desorption is carried out at ambient pressure when the adsorption/desorption is carried out by the first bed of adsorption 31 and the first heating element 32, and that the gasification device 1c comprises a stage valve 44 allowing or blocking fluid communication between the capture stage and the compression stage. Furthermore, the gasification device 1c may not include a supply valve as illustrated in FIG. 1c, which reduces the cost of the device.

In this case, the compression stage comprises a second adsorption bed 45 and a second heating element 46. It is connected to the ambient air by a second evacuation valve 42 and has a injection of carbon dioxide into the container through an injection valve 43.

In this exemplary embodiment, the computer is suitable for controlling the implementation, by the gasification device 1c, of the following steps.

During an adsorption phase, the fan 51 of the air supply circuit 5 is started, the inlet valve 52 and the first outlet valve 62 are open. and stage valve 44 is closed. In this way, the ambient air enters the capture stage via the air supply circuit 5 and passes through the adsorption element 31 before being evacuated by the air evacuation circuit 6. Air cannot enter the compression stage or the container once the stage valve is closed. Thus the air flows through the adsorption element 31 at room temperature and carbon dioxide is adsorbed by the adsorption element 31. This is point 1 on the graph of Figure 3.

During a desorption phase, the stage valve 44 is open to allow fluid communication between the capture stage and the compression stage. The third valve 43 is closed so that the fluid communication between the compression stage and the container 7 is blocked. The second evacuation valve 42 is open so that a fluidic communication is established between the capture stage 3 and the ambient air via the compression stage 4. Optionally but advantageously, the valve of evacuation 62 is closed so that the air necessarily circulates from the capture stage to the compression stage without part of the air being evacuated by the air evacuation circuit 6.

The desorption takes place by the activation of the first heating element 31 heating the first adsorption bed, or by the activation of the electrical power source by energizing the stack of electrodes at the second voltage and by the action of the fan circulating the air from the capture stage to the compression stage before being evacuated by the fluid communication with the ambient air at the level of the valve 42.

The carbon dioxide is desorbed from the adsorption element 31 in the capture stage by heating or by applying an electric voltage, thus charging the air in the capture stage with carbon dioxide in significant proportions at ambient pressure. This is point 2 in the graph in Figure 3.

[0140] By air laden with carbon dioxide, it must be understood in the present application that the concentration of carbon dioxide in the air laden with carbon dioxide is significantly higher than the average carbon dioxide concentration of the air. 'ambiant air. In this case, the concentration of carbon dioxide in the ambient air is around 0.04% while the air loaded with carbon dioxide in the capture stage during desorption has a concentration greater than 1%.

The air loaded with carbon dioxide desorbed from the adsorption element 31 is driven by the fan 51 towards the compression stage 4 comprising the second adsorption bed 45. [0142] In this way, when it passes through the second adsorption bed 45 of the compression stage, the second adsorption bed 45 adsorbs carbon dioxide from the air laden with carbon dioxide in much higher concentrations. larger than the first adsorption bed 31. This is point 3 on the graph of FIG. 3. The air, discharged of its carbon dioxide after passing through the second adsorption bed 45, is then evacuated from the gasification device 1c via the fluidic communication between the compression stage 4 and the ambient air at the level of the second evacuation valve 42.

The desorption is therefore carried out either by heating the first adsorption bed 31 or by energizing the stack of electrodes, so as to charge the air in the capture stage with carbon dioxide. carbon coupled with ventilation of the capture stage by the fan 51 to the compression stage so that the second adsorption bed 46 captures the carbon dioxide from the air laden with carbon dioxide. [0145] Next, the compression is implemented in the compression stage when each of the stage valve 44, the second valve 42 and the third valve 43 are closed. The compression stage is therefore hermetically sealed to the outside air and to the capture stage. Thus, when the second heating element 46 heats the second getter bed 45, the second getter bed gradually releases the adsorbed carbon dioxide from the charged air so that the carbon dioxide pressure in the compression stage gradually increases. This is point 4 on the graph in Figure 3.

When the carbon dioxide pressure in the compression stage is greater than the predetermined pressure threshold, the injection valve 43 is opened so that the compression stage is placed in fluid communication with the container, by example through the injection duct, and that the compressed carbon dioxide is gradually injected into the container.

The desorption element is deactivated and the fan can be stopped when the device 1c is in a compression phase. In this case, during the compression and injection phases, the fan 51 can continue to turn and the first evacuation valve 62 can be opened again to carry out a new adsorption phase in parallel.

Referring to Figure 1d is now presented a fourth embodiment of gasification device 1d. This fourth embodiment differs from the third previous embodiment insofar as the evacuation valve 62 is replaced by a second movable wall 63.

As illustrated in Figure 1d, the air evacuation circuit 6 comprises a second movable wall 63 of the capture stage. This second movable wall 63, when open, allows fluid communication between the ambient air and the capture stage.

The second mobile wall 63 can for example be a rotary wall which opens by rotation around an axis. The second mobile wall 63 can also be a sliding wall to place the first adsorption bed in communication with the outside air. The wall can slide both horizontally and vertically as shown in Figure 1d. It may include gripping means, for example a handle, so that the user can open it. Alternatively, it can be opened by the action of a motor.

The second mobile wall 63 makes it possible to expel the air via the evacuation circuit 6 more easily while making it possible to facilitate access to the ambient air to the absorption element 31 so that the phase adsorption is faster.

In this embodiment, the computer is adapted to control the same steps as in the embodiment presented with reference to FIG. 1c by replacing the actions performed on the evacuation valve by the same actions performed on the second movable wall 63.

[0153] In particular, the second movable wall 63 is open in the adsorption phase of the device so that the ambient air evacuated by the evacuation circuit is greater, which makes it possible to increase the power of the fan and therefore reduce the adsorption time. It is then closed in the desorption phase so that the air laden with carbon dioxide does not escape from the housing via the movable wall 63 but passes through the compression stage to load the second compression bed in carbon dioxide.

In the same way as before, during the compression and injection phases, the fan 51 can continue to turn and the second movable wall 63 can be opened again to perform a new adsorption phase in parallel.

With reference to FIG. 1e, a fifth embodiment of the gasification device 1e is presented. This fifth embodiment graphically illustrates an embodiment comprising the stack of electrodes 311 powered by the electrical energy source and in this case by the battery 321 . As explained previously, the device allows adsorption by a combination of the first adsorption bed 31 and the first heating element 32 or by a combination of the stack of electrodes 311 and the source of electrical energy, for example battery type 321, to allow adsorption and desorption of carbon dioxide from the ambient air. Furthermore, in the context of a desorption combining the first adsorption bed 31 and the first heating element 32, the desorption phenomenon can be improved by reducing the pressure of the capture stage via the action of the pump 41.

The devices and the method of gasification presented above thus make it possible to gasify a drink from carbon dioxide in the ambient air. In this way, a user of the gasification device no longer needs to buy or refill the carbon dioxide cartridges necessary for the operation of the gasification devices of the prior art. The gasification device according to the invention allows, in particular by eliminating cartridge dioxide cartridges and by recovering carbon dioxide from the ambient air, a considerable reduction in polluting emissions. In particular, the carbon impact of the beverage gasification process according to the invention is negative. Furthermore, the gasification device presented allows direct use of the ambient air in the sense that the ambient air is not conditioned prior to its passage through the device and more precisely prior to its passage through the adsorption element. .
