BACKGROUND ART

Mineral water obtained from an underground layer does not always have the desired properties to be bottled directly in containers, such as bottles. For example, carbon dioxide is often added to the mineral water in order to obtain a sparkling mineral water. Carbon dioxide gives the mineral water a sparkling character and ensures a pleasant, refreshing and stimulating mouthfeel when consumed by a person.

A method and device for adding carbon dioxide to water is described in US 7114707B2. US 7114707B2 discloses a water carbonation method and apparatus consisting of a square mixer within a carbon dioxide gas chamber. Carbon dioxide is added above the level of the water. A rotating member of the mixing engine then mixes the water and carbon dioxide into a carbonated solution.

US7114707B2 has the problem that the water to which carbon dioxide gas is added is not standardized, so that it is problematic to be able to guarantee a continuous and equal quality of the carbonated water. Furthermore, US7114707B2 has the problem that insufficient measures are being taken to optimize the absorption capacity of the water for carbon dioxide gas.

The present invention aims at least to find a solution for some of the above problems.

DETAILED DESCRIPTION

The citation of numerical intervals by the end points includes all integers, fractions and / or real numbers between the end points, including these end points.

The term mineral water, as used in this text, is to be understood as potable water that has been extracted from an underground layer and has also obtained official recognition from a government of the territory where the underground layer is located, such as the Belgian federal government .

The term bottled-ready, as used in this text, is to be understood as referring to a state of mineral water in which the composition of the mineral water meets certain predetermined conditions and then be filled or bottled in containers, such as bottles, and as such persons to be offered for consumption.

The term venting, as used in this text, can be understood as the removal of air, including gases present in the air, and free, unbound, carbon dioxide from a liquid. The term degassing can be used as a synonym for the term venting.

The term vented mineral water, as used in this text, can be understood as mineral water from which the dissolved air including oxygen and free, unbound, carbon dioxide is at least partially removed.

In a first aspect, the invention relates to a method for making carbonated mineral water ready for bottling, comprising the steps of providing mineral water and subsequently adding carbon dioxide to the mineral water, the step of adding carbon dioxide comprising the steps of:

- partially filling a substantially sealed carbonation vessel with the mineral water to a predetermined level;

- applying carbon dioxide gas in the carbonation vessel; and

- discharging carbonated mineral water thus formed from the carbonation vessel, wherein the mineral water is first vented before adding the carbon dioxide gas.

BE2017 / 5969

The measure of venting the mineral water before adding carbon dioxide to the mineral water, according to the first aspect of the present invention, ensures that a mineral water thus vented is obtained that has a greater capacity to take in carbon dioxide, or, in other words, can absorb faster and more carbon dioxide than a mineral water that was not vented beforehand. Furthermore, the venting of mineral water implies a standardization of the mineral water, which is conducive to ensuring a continuous and equal quality of the final carbonated mineral water. This measure is certainly not obvious for a person skilled in the art, since such a person would rather opt to improve parameters for carbon dioxide gas addition per se, instead of treating the mineral water in advance so as to to increase the absorption capacity for carbon dioxide.

According to a preferred embodiment, after the step of adding carbon dioxide to the mineral water, the mineral water is filled or bottled in containers, such as bottles. Said containers, such as bottles, can be made of any suitable material as known in the art, of which polyethylene terephthalate and glass are non-limiting examples. Preferably, said containers are reusable or recyclable.

The steps of partially filling a substantially sealed carbonation vessel with the mineral water to a predetermined level and of introducing carbon dioxide into the carbonation vessel can, according to embodiments, be carried out in this order or the reverse order.

According to a preferred embodiment, the mineral water is sprayed in the form of small droplets in an atmosphere of carbon dioxide gas that was previously introduced into the carbonation vessel. Carbon dioxide gas is hereby dissolved in the water droplets, after which the water droplets carry the carbon dioxide gas to a body of water that forms in the carbonation vessel through the many water droplets. A relatively high pressure level is preferably used in the carbonation vessel.

In a preferred embodiment, mineral water is applied to a predetermined level in the carbonation vessel and carbon dioxide is added to the space above the water, with a 6: 1 to 2: 1, more preferably a 5: 1 to 3: 1 and even more preferably a 4.5: 1 to 3.5: 1 ratio of the

BE2017 / 5969 water volume relative to the volume of the carbon dioxide gas above the water is assumed. This ratio allows a good absorption of carbon dioxide by the water.

According to a preferred embodiment, the mineral water is vented by the mineral water at a temperature of 28 to 40 ° C, more preferably of 30 to 38 ° C, even more preferably of 32 to 36 ° C and even more preferably of 33 to 35 ° C in a substantially closed venting vessel in which there is an underpressure of -0.06 to -0.1 MPa, more preferably from -0.07 to -0.09 MPa and even more preferably from - 0.075 to -0.085 MPa, wherein gases are released from the mineral water present in the venting vessel, thus obtaining a vented mineral water, and wherein the released gases are vented and after a certain time the vented mineral water is vented to subsequently add carbon dioxide to it.

Said conditions are optimally suited to obtain a strong venting of the mineral water. The high underpressure ensures that the temperature of the mineral water does not have to become too high to reach the boiling point of the mineral water. These moderate temperatures are less likely to cause damage to the carbonation vessel than higher temperatures. Under the conditions of moderately elevated temperature and strongly reduced pressure, gases can escape from the mineral water very well. The determined time in which the mineral water remains in the venting vessel can be selected based on the amount of mineral water and the desired degree of venting of the mineral water. The mineral water is preferably vented according to a continuous process, wherein mineral water to be vented is continuously transferred into the venting vessel and wherein vented mineral water is continuously discharged from the venting vessel. The underpressure or the vacuum is preferably maintained by a working vacuum pump which is connected to the venting vessel by means of one or more pipes. According to these one or more pipes, the gases released from the mineral water can be discharged.

According to a preferred embodiment, before transferring the mineral water to the venting vessel in which there is an underpressure of -0.06 to -0.1 MPa, more preferably from -0.07 to -0.09 MPa and even more preferably from -0.075 to -0.085 MPa, the mineral water is first transferred and the mineral water remains in a substantially closed state for a certain time.

BE2017 / 5969 venting vessel in which there is an underpressure of -0.01 to -0.04 MPa and more preferably from -0.02 to -0.03 MPa. Decreasing the pressure in two steps is better achieved with standard and not excessively expensive equipment than reducing the pressure in one step. In addition, in the first step, with a vacuum of -0.01 to -0.04 MPa and more preferably from -0.02 to -0.03 MPa, gases are already released from the mineral water. Afterwards, in a second step, with an underpressure of -0.06 to -0.1 MPa, more preferably from -0.07 to -0.09 MPa and even more preferably from -0.075 to -0.085 MPa, subsequently remaining gases are released from the mineral water that was already pressurized in said first step. This is certainly not obvious for a person skilled in the art, since such a person would rather opt to adjust merely general temperature pressure settings, instead of an underpressure in two well-defined steps on build.

Preferably after mineralizing the mineral water comprises, by means of an embodiment of a method according to the first aspect of the present invention, at most 2 g / l, more preferably at most 1.5 g / l, even more preferably at most 1 g / l and even more preferably at most 0.5 g / l carbon dioxide, and at most 10 mg / l, more preferably at most 5 mg / l and even more preferably at most 3 mg / l dissolved oxygen. Such a low oxygen content contributes to a good absorption capacity of the mineral water for carbon dioxide.

According to a preferred embodiment, the mineral water is introduced into a substantially closed venting vessel by spraying the mineral water in small droplets within the venting vessel by means of a sprayer. By providing the mineral water in the form of small drops, it will be possible to release gases more quickly from the mineral water than if the mineral water were to be present as a large volume, whereby inside this volume internal water can only be vented later. This is a measure that is very conducive to accelerating the speed of venting.

According to a preferred embodiment, a volume of the mineral water present in the venting vessel during venting corresponds to 23 to 45 volume percent, more preferably 26 to 42 volume percent, even more preferably 29 to 39 volume percent and even more preferably 32 up to 36 volume percent of the total volume of the venting vessel. Such filling is

BE2017 / 5969 large enough to achieve a sufficient circulation rate of the venting of mineral water and at the same time not too large to still be able to bring the mineral water quickly to its boiling point and to be able to discharge the released gases quickly.

According to a preferred embodiment, after venting the mineral water, the vented mineral water is first cooled to a temperature of 5 to 25 ° C, more preferably of 8 to 22 ° C and even more preferably of 10 to 20 ° C before carbon dioxide gas to add. The carbon dioxide can be absorbed better at a lowered temperature than at a higher temperature. The mineral water temperatures mentioned here are ideally suited to incorporate carbon dioxide into the mineral water in a later step.

According to a preferred embodiment, during the application of carbon dioxide gas in the carbonation vessel, the pressure of the carbonation vessel is brought to a pressure level of 0.4 to 0.7 MPa and more preferably of 0.5 to 0.6 MPa. This increased pressure is conducive to carbon dioxide gas uptake by the mineral water.

According to a preferred embodiment, during the step of adding carbon dioxide to the mineral water, the carbon dioxide is applied to the carbonation vessel to a carbonated mineral water with a carbon dioxide content of 6.5 to 8.5 g / l, more preferably of 6.8 up to 8.2 g / l, even more preferably from 6.9 to 8.0 g / l and even more preferably from 7.0 to 7.4 g / l. Such a content of carbon dioxide in a carbonated mineral water is highly desirable for a consumer because it imparts a sparkling character to the mineral water and, in addition, provides a pleasant, refreshing and stimulating mouthfeel when consumed.

According to a preferred embodiment, the carbonation vessel is filled with the mineral water until the volume of the mineral water present in the carbonation vessel corresponds to 34 to 56 volume percent, more preferably 37 to 53 volume percent, even more preferably 40 to 50 volume percent and even more more preferably 43 to 47 volume percent of the total volume of the carbonation vessel. This ratio allows a particularly good absorption of carbon dioxide by the water.

According to a preferred embodiment, the carbon dioxide is introduced into the carbonation vessel above the level of the mineral water. According to an

BE2017 / 5969, the carbonation vessel is filled with the mineral water to a predetermined level, after which carbon dioxide is added to the space above the water. In this way carbon dioxide is brought into contact with and dissolved in the water. In a preferred form, the mineral water can herein be agitated, for example by rotating a horizontal rotating paddle with blades extending from the water into space above the water in the carbon dioxide gas. In a preferred form, the carbon dioxide gas is introduced into the carbonation vessel by means of a sprayer in a finely divided form. Such a finely divided form is conducive to a good absorption of the carbon dioxide by the mineral water.

According to a preferred embodiment, the carbon dioxide is from liquid CO2 with a purity of more than 99.99%. Preferably, the liquid CO2 is suitable for use in food and beverages, or, in other words, it is preferably liquid CO2 food grade. Preferably said liquid CO2 complies with European directive 96/77 / EC, European directive 98/96 / EC, European regulation 178/2002, European regulation 852/2004, European regulation 315/93 / EC, the carbon dioxide guidelines of the ISBT (International Society of Beverage Technologists, Revision April 1999) and / or the carbon dioxide guidelines of the EIGA (European Industrial Gases Association, Revision April 1999). The liquid CO2 is preferably stored in a tank. Preferably, CO2 is ordered upon reaching a 30% filling of the tank and the tank is then supplemented to a full filling. Liquid CO2 can be converted into gaseous CO2 or carbon dioxide by means of an evaporator.

In a second aspect, the invention relates to a device for making carbonated mineral water ready for bottling, comprising:

- a carbonation vessel;

- a mineral water reservoir;

- a water inlet for access of the mineral water to the carbonation vessel;

- a carbon dioxide gas reservoir;

- a carbon dioxide gas inlet for contacting the carbon dioxide gas reservoir and the carbonation vessel;

- a gas outlet for discharging gases from the carbonation vessel; and

- a water outlet for draining carbonated mineral water,

BE2017 / 5969 wherein the device between the mineral water reservoir and the carbonation vessel comprises a vacuum venter, which vacuum venter comprises a substantially sealed venting vessel which is provided with a water inlet for receiving mineral water, a water outlet for draining vented mineral water and a gas outlet for draining of gases, which gas outlet can be connected to a vacuum line that can be connected to a vacuum pump.

The measure of providing a vacuum venter allows the venting of mineral water before adding carbon dioxide to the mineral water in the carbonation vessel by adding carbon dioxide from the carbon dioxide reservoir. This measure according to the second aspect of the present invention therefore ensures that by venting by means of the vacuum venter a mineral water thus vented is obtained which has a greater capacity to take in carbon dioxide gas, or, in other words, can take in faster and more carbon dioxide gas. then a mineral water that was not vented beforehand. Furthermore, the venting of mineral water implies a standardization of the mineral water, which is conducive to ensuring a continuous and equal quality of the final carbonated mineral water. This measure is certainly not obvious for a person skilled in the art, since such a person would rather opt to improve the arrangement for carbon dioxide gas addition per se, instead of adding a device for Pre-treatment of mineral water in order to increase the absorption capacity for carbon dioxide.

For the manner and the different steps in which the mineral water can be vented and in which carbon dioxide can then be added to the mineral water, by means of the device according to the second aspect of the present invention, reference is made to the above discussion of the method according to the first aspect of the present invention. .

According to preferred embodiments, the water inlet is designed as a water inlet valve, the carbon dioxide gas inlet is implemented as a carbon dioxide gas inlet valve, the gas outlet is implemented as a gas outlet valve and / or the water outlet is implemented as a water outlet valve. According to a preferred embodiment, the device comprises a pump for the forced flow of the mineral water. This way the mineral water can flow through the breather and the carbonation tank.

According to a preferred embodiment, said venting vessel has an elongated symmetrical shape and said venting vessel is arranged horizontally along a longest side, wherein the venting vessel has a length to height ratio of 4: 1 to 2: 1, more preferably of 3.5: 1 to 2.5: 1 and even more preferably from 3.2: 1 to 2.8: 1. Such geometry and arrangement of the venting vessel provides a large free surface of mineral water that is provided in the venting vessel. This benefits a smooth venting of the mineral water in the venting vessel.

According to a preferred embodiment, one or more nozzles are provided in the venting vessel for spraying the mineral water into the venting vessel, which nozzles are to be connected and are preferably connected to said water inlet. By spraying mineral water through a sprayer, the mineral water can provide small drops in the form. By providing the mineral water in the form of small drops, it will be possible to release gases more quickly from the mineral water than if the mineral water were to be present as a large volume, whereby inside this volume internal water can only be vented later. Said nozzles are very conducive to accelerate the speed of venting.

According to a preferred embodiment, one or more nozzles are provided in the carbonation vessel for spraying carbon dioxide into the carbonation vessel, which nozzles are connectable and are preferably connected to said carbon dioxide gas inlet. Through the sprayer mentioned, the carbon dioxide can be introduced into the carbonation vessel in a finely divided form. Such a finely divided form is conducive to a good absorption of the carbon dioxide by the mineral water.

In a third aspect, the invention relates to a use of a device according to the second aspect of the present invention in a method according to the first aspect of the present invention. Accordingly, all technical achievements and positive features of a device according to the second aspect of the present invention are combined with those of a method according to the first aspect of the present invention.

BE2017 / 5969

Through a pump 2, mineral water from a subterranean layer is pumped up and received in a mineral water reservoir 1. From this reservoir, the mineral water flows past a heat exchanger 12, where the mineral water is heated to a temperature of 33 to 35 ° C, and the mineral water then flows to a vacuum venter 3, which vacuum venter 3 comprises a substantially sealed venting vessel 4 which is provided with a water inlet 5 connected to a water pipe 10 which is also connected to said mineral water reservoir 1 for receiving mineral water, a water outlet 6 connected to a water pipe 11 for discharging vented mineral water and a gas outlet 7 for discharging gases, which gas outlet 7 is connected to a vacuum line 8 connected to a vacuum pump 9.

When filling the venting vessel 4 with mineral water and when draining vented mineral water from the venting vessel 4, it is preferably ensured that a volume of the mineral water present in the venting vessel during venting corresponds to 32 to 36 volume percent of the total volume of the venting vessel 4. Such filling is large enough to obtain a sufficient turnover rate of the venting of mineral water and at the same time not too large to still be able to bring the mineral water quickly to its boiling point and to be able to discharge the released gases quickly.

By means of said vacuum pump 9, the pressure in the venting vessel 4 is reduced in a first step to an underpressure of -0.02 to -0.03 MPa. In a second step, by means of said vacuum pump 9, the pressure in the venting vessel 4 is further reduced to an underpressure of -0.075 to -0.085 MPa. The above-mentioned temperature and the underpressure stated here are optimally suitable for obtaining a strong venting of the mineral water. The high underpressure ensures that the temperature of the mineral water does not have to become too high to reach the boiling point of the mineral water. These moderate temperatures are less likely to cause damage to the carbonation vessel than higher temperatures. Under the conditions of moderately elevated temperature and strongly reduced pressure, gases can escape from the mineral water very well.

In the first step mentioned, gases are already released from the mineral water at the underpressure of -0.02 to -0.03 MPa. Afterwards, in a second step, with a negative pressure of -0.075 to -0.085 MPa, remaining gasses can then be released from the mineral water that was already pressurized in

BE2017 / 5969 mentioned first step. Released gases can be discharged from the venting vessel 4 via said vacuum line 8 which is connected to the vacuum pump 9.

Mineral water is transferred from the mineral water reservoir 1 to the venting vessel 4 by means of said water pipe 10 and leaves the venting vessel 4 by a second water pipe 11. The aforementioned water pipe 10 flows into a sprayer 28 which transfers the mineral water into the venting vessel 4 in the form of small drops. By providing the mineral water in the form of small drops, it will be possible to release gases more quickly from the mineral water than if the mineral water were to be present as a large volume, whereby inside this volume internal water can only be vented later. This is a measure that is very conducive to accelerating the speed of venting.

Said second water pipe comprises a branch in the form of a third water pipe 13, which third water pipe 13 is in contact with said water pipe 10 along which the mineral water was initially brought to the venting vessel 4. A loop is thus obtained which makes recirculation of the mineral water through the venting vessel 4 possible. For example, a certain volume of mineral water can first be vented at an underpressure of 0.02 to -0.03 MPa, after which the vented mineral water leaves the venting vessel 4 and is only brought back to the venting vessel 4 when an underpressure of -0.075 to - 0.085 MPa has been applied. With pipe splits, the flow of mineral water is controlled in a desired direction by means of multi-way valves 14, 15.

After leaving the venting vessel 4, the vented mineral water flows via a water pipe 16 over a heat exchanger 17 where the vented mineral water is cooled to a temperature of from 10 to 20 ° C. The carbon dioxide can be absorbed better at a lowered temperature than at a higher temperature. The mineral water temperatures mentioned here are ideally suited to incorporate carbon dioxide into the mineral water in a later step.

Subsequently, the vented mineral water flows via a water pipe 18 to a carbonation tank 19 via a water inlet 20, preferably designed as a water inlet valve, in the carbonation tank 19 for access of the mineral water to the carbonation tank 19. The carbonation tank 19 further comprises a carbon dioxide gas inlet 21, preferably designed as a carbon dioxide gas inlet valve, which via a carbon dioxide gas line 22

BE2017 / 5969 is connected to a carbon dioxide gas reservoir 23. Furthermore, the carbonation vessel 19 comprises a gas outlet 24, preferably designed as a gas outlet valve, in connection with a gas outlet line 25 for discharging gases from the carbonation vessel 19 and the carbonation vessel 19 comprises a water outlet 26 which communicates with a water pipe 27 for discharging carbonated mineral water.

The carbonation vessel 19 is partially filled with the vented mineral water until the volume of the mineral water present in the carbonation vessel 19 corresponds to 43 to 47 volume percent of the total volume of the carbonation vessel 19. This ratio allows a particularly good uptake of carbon dioxide gas by the mineral water to. Via a sprayer 29 located in the carbonation vessel 19 and in communication with said carbon dioxide gas inlet 21, carbon dioxide gas is introduced into the carbonation vessel 19 in a finely divided form. Such finely divided form is conducive to a good absorption of the carbon dioxide gas by the mineral water.

By adding carbon dioxide gas in the carbonation vessel 19 in the presence of the vented mineral water, the mineral water is supplied with carbon dioxide gas until a carbonated mineral water with a carbon dioxide content of 6.5 to 8.5 g / l is obtained. A pressure of 0.5 to 0.6 MPa is applied to the carbonation tank by means of a pump (not shown) during the addition of the carbon dioxide to promote carbon dioxide gas uptake by the mineral water.

The carbonated mineral water thus obtained is further distributed for human consumption by means of the latter water pipe 27.
