Description

technical field

[0001] The present invention relates to a device for treating fluids, particularly for treating food-grade fluids such as wines or distilled spirits. The device comprises a stirring element and at least one magnetic element, arranged to combine their effects on the fluids to be treated. State of the art

[0002] Fluid treatment devices involving vortices are already known. For example, US patent 2004124136 presents such a device for water purification. However, such devices are difficult to apply to complex food-grade fluids such as wine or distilled spirits. The stirring effects can be detrimental to the organoleptic characteristics of such beverages.

[0003] Documents CN206887079H, WO2014 / 079809 A1, and US5997812 A describe systems for processing food fluids guided in a tube and subjected to magnetic fields.

[0004] Magnetic field generators can also be used for fluid processing. For example, magnetic fields are used in conjunction with electrically conductive fluids in devices such as magnetohydrodynamic (MHD) converters, which set the fluids in motion. Passivation effects on water under the influence of such magnetohydrodynamic converters have been described. The application of magnetic fields to wine is also described in US20030003189 as beneficial for softening certain taste characteristics such as acidity or astringency.

[0005] However, there is room for improvement in such processes, particularly in controlling the organoleptic potential and the evolution of the beverage's properties over time, both in terms of taste and texture. The present invention aims, in particular, to develop, stabilize, or optimize the organoleptic potential of complex fluids such as wine or distilled spirits. Brief summary of the invention

[0006] One object of the present invention is to provide a device for treating food fluids, such as wine or other fermented alcoholic beverages, or distilled spirits, to preserve, improve, or stabilize their organoleptic properties and their evolution over time. The present invention makes it possible, in particular, to limit or eliminate all or part of the additives used for preserving beverages. Additives used for preserving beverages include, but are not limited to, sulfites. Preserving the beverage includes tartaric stabilization, where appropriate. Preserving, improving, or stabilizing such beverages also includes increasing or decreasing the concentration of dissolved gases, especially oxygen.

[0007] More generally, the objective of the present invention is to control the organoleptic potential of beverages such as wine or other fermented alcoholic beverages like beer, or distilled spirits. Controlling such properties includes adapting them to a specific audience, correcting any defects, diminishing or accentuating certain characteristics, and creating new or little-known organoleptic characteristics, without being limited to these aspects alone. Controlling the organoleptic properties of such a beverage includes its aromatic refinement. Controlling organoleptic properties also includes eliminating or reducing astringency, acidity, or other taste characteristics. Controlling organoleptic properties also includes their preservation and stabilization.In this case, the aging or maturation processes can be shortened, lengthened, or modified to correspond to specific organoleptic properties.

[0008] The term "organoleptic" here refers to all aspects relating to the sensation experienced by the consumer, whether it be taste, smell, mechanical perception or texture, visual perception, or other types of perception.

[0009] A particular objective of the present invention is to stabilize physico-chemical parameters, such as pH, surface tension, rheological parameters, redox potentials, resistivity, saturation temperature or turbidity, or to modify them, or to modify their evolution over time.

[0010] Another objective of the present invention is to simplify the production processes of such beverages, in particular by eliminating one or more process steps. In a winemaking process, the fining or filtering steps, or both, can be simplified or eliminated. According to one aspect, the treatment of fluids using the present invention can take place at the end of the production process, at the time of storage for marketing. Storage includes bottling. Alternatively, a treatment step according to the present invention can take place between two already known steps. For example, before fermentation, or during fermentation if the liquids are fermented. The treatment according to the present invention can be carried out before distillation if the fluid is distilled.

[0011] According to a particular embodiment, the treatment process according to the present invention is continuous and can be integrated into a pre-existing pipeline allowing the fluid to be treated to flow from one location to another, for example, from a settling tank to a fermentation tank or from a maturation tank to a storage tank. Advantageously, the treatment process does not impact the duration of the fluid production process; in particular, it does not lengthen it, due to its integration into existing equipment and its continuous operation. Even more advantageously, the treatment process according to the present invention reduces the fluid production time prior to its commercialization.

[0012] To this end, a fluid treatment device is presented. The fluid treatment device comprises a mixing element of length and at least one magnetic device, characterized in that the mixing element has several grooves on the inner wall of its central part over a length, the grooves being oriented non-linearly with the longitudinal axis of the mixing element, arranged along the mixing element in a disruptive manner, offset from one another so as to divide the flow of fluid to be treated when it passes from one groove to the next, and that the at least one magnetic device is arranged around the mixing element at places not having grooves.

[0013] According to a specific arrangement, the magnetic device(s) are polarized so that the South-North field lines are orthogonal to the direction of flow of the fluids being treated. For this purpose, the magnetic device can be circular, positioned around the mixing element, and designed so that its South-North polarity is radial, that is, oriented from the center of the circular magnetic device to its periphery or, conversely, from its periphery to its center. Alternatively, the magnetic device(s) are polarized so that the South-North magnetic field lines are parallel to the direction of flow of the fluids being treated.

[0014] In a preferred arrangement, the splines of the mixing element are paired so that the orientations of the splines in each pair are reversed relative to each other. Several sets of splines are arranged along the mixing element. These sets of splines are preferably offset from one another to divide the flow of the fluid being processed.

[0015] According to a specific arrangement, the maximum width of the grooves is equal to or less than half the diameter of the mixing element. The grooves can be, for example, helical in shape, although other shapes are possible.

[0016] The permanent magnets surrounding the mixing tube may be protected by magnetic shielding, a protective polymer layer, or a combination of magnetic shielding and a protective polymer layer. The device may also include an enclosure whose length is less than or equal to, or greater than, that of the mixing element.

[0017] The fluid treatment device may further include one or more light irradiation devices, particularly in the ultraviolet range. Such light irradiation devices are advantageously positioned around the mixing tube, especially where the mixing tube has grooves. The light irradiation device may be part of an irradiation module that can be integrated into or added to the treatment device.

[0018] The present invention also covers a method for treating a fluid. The fluid is fed into the mixing element, where it passes through a first magnetic field, then through a series of grooves, or sets of grooves, which induce disturbances in the fluid flow. The fluid then passes through a second magnetic field before being collected. The disturbances introduced by the grooves in the fluid flow are of the vortex type.

[0019] Preferably, the first and second magnetic fields have opposite polarities to each other. Brief description of the figures

[0021] The device D of the present invention includes a mixing element 1allowing the division and homogenization of fluids. The mixing element 1 is suitable for mixing a fluid F using a continuous process, meaning one that can be fed permanently and without interruption. Such a process is often simpler and more economical than batch processes. The mixing element 1 According to the present invention, it therefore comprises a power supply A, by which the fluid to be treated F is introduced into the mixing element 1, and an exit S, by which the treated fluid F' is collected. The fluid flow to be processed F is continuous and the flow rate can be regulated upstream, notably by means of a pump P.

[0022] The mixing element 1 preferably includes a cylindrical tube 1c, one end of which constitutes, or is equipped with, a power supply system A fluid to be treatedF and whose other end constitutes, or is equipped with, a system for collecting the treated liquid F'. Food A may alternatively or in addition include a diaphragm 1a, allowing the regulation of the fluid flow to be processed F at the inlet of the mixing element 1. Collection of the treated fluid F' at the end S of the mixing element 1 can be done directly or via a reservoir R. One or the other, or both, of the power supplies A and exit S may include a connecting flange 1b. If applicable, the diaphragm 1a can be included in the connecting flange 1b. The connecting flange(s) 1b allow the mixing element to be connected 1 with any type of conduit such as flexible or metallic conduit.

[0023] The velocity of the fluid to be processed F within the mixing element 1 is preferably between 0.5 and 3 m / s. The velocity of the fluid to be treated F can advantageously be between 1 and 1.5 m / s.

[0024] The flow rate of the fluid to be treated F is regulated by the diaphragm 1a. Alternatively, the flow rate can be regulated directly by the feed pump. P. The flow rate of the fluid to be treated F can be adapted to the dimensions of the mixing element 1, in particular its diameter d, its length L, and other parameters characterizing it.

[0025] The inner wall of the mixing element 1 is equipped with grooves 1d oriented non-linearly with the longitudinal axis of the mixing element 1. The grooves 1dare preferably oriented at an angle between 30 and 50 degrees relative to the longitudinal axis of the mixing element 1. The longitudinal axis of the mixing element 1 heads in the direction x on the figure 1 , and corresponds to the general direction of flow of the fluid being treated F from food A until the exit S of the mixing element 1. The grooves 1d are preferably oriented at an angle of approximately 45 degrees to the longitudinal axis of the mixing element 1. A groove 1d for example, it can take the form of a spacer fixed to the inner wall of the mixing element. 1, of straight or curved shape, and of variable width. The width of a groove 1d for example, it could correspond to half, or be less than half, of the diameter d of the mixing element1. The length of a groove 1d is variable but significantly less than the length of the mixing element 1, so that multiple grooves can be arranged 1d one after the other along the mixing element 1. The grooves 1d are arranged along the mixing element 1 in a disruptive manner. They are offset from each other so as to divide the flow of fluid to be treated F as it passes through a groove 1d to the next one. The grooves 1d They can, for example, be arranged in a staggered pattern or offset by an angle of 20, 30, 40 or 50 degrees from each other.

[0026] Preferably the grooves 1d are arranged in pairs on the inner wall of the mixing element 1, so that they are facing each other. The grooves 1dThe elements of a pair can then be placed symmetrically or inverted, or simply offset by a certain angle from each other.

[0027] According to a particular arrangement, the pairs of grooves 1d are arranged in reverse order, that is to say, the orientation of the grooves 1d The opposite side is reversed. The width of the grooves 1d may correspond to half the diameter d of the mixing element 1 in such a way that they meet at the center of the mixing element 1. If they are less than half the diameter in width d, then part of the fluid F the material to be processed can pass through the center of the mixing element. 1 without coming into contact with the grooves 1d.

[0028] Preferably, the mixing element has several pairs of grooves. 1darranged opposite each other. For example, the mixing element 1 may have 3, 5, 7, 10, 15, or more than twenty pairs of grooves 1d depending on the needs of the treatment.

[0029] According to a variant of the present invention, the grooves 1d may not all have the same width along the mixing element 1.

[0030] According to another variant, the grooves 1d are all identical.

[0031] According to another variant, the grooves 1d They can have a non-constant width; for example, they can be tapered at one or both ends and bulge in the middle. Alternatively, they can be triangular, meaning one end is wider than the other. Other shapes are also possible.

[0032] According to another embodiment of the present invention, the grooves1d can be matched in groups of 3 or 4 and not only in pairs.

[0033] According to another embodiment of the present invention, the grooves 1d are helical. figures 5a, 5b and 5c show examples of such 1d grooves, which may, for example, include 2 helical channels ( figure 5a ) or three helical channels ( figure 5b ) or even 4 helical channels ( figure 5c ).

[0034] The geometry, number, arrangement and dimensions of the grooves 1d can be determined in such a way as to divide the flow F of the liquid to be treated in increasingly thin and dissociated flow films. The geometry, number, arrangement and dimensions of the grooves 1d can also, or alternatively, be determined so as to promote vortices in the flow F of the liquid to be treated. The proportions of lamellar flow and turbulence in the flow FThe flow of liquid can be optimized through the parameters of the grooves. 1d. There figure 6 diagram the divisions F1, F2, F3 liquid flows through the grooves 1d successive.

[0035] In one variant, the fluted sets are contiguous to each other along the length of the mixing element. 1.

[0036] According to another provision, the fluting patterns 1d are spaced apart from each other along the mixing element 1.

[0037] According to a particular arrangement, the fluting patterns 1d are grouped into several separate groups along the mixing element 1.

[0038] The mixing element 1 maybe a metal cylinder 1c, particularly in stainless steel, or austenitic stainless steel. The grooves 1d are also made of stainless steel, or austenitic stainless steel. The mixing element1 and the grooves 1d are preferably made of a non-magnetic material.

[0039] Alternatively, the mixing element 1 It can be a cylinder transparent to light, particularly ultraviolet light. Such a transparent cylinder can be made, for example, of quartz, allowing the transmission of wavelengths between 100 nm and 400 nm, especially between 100 nm and 300 nm. The grooves 1d They can then be metallic, made of a non-magnetic metal, or of a non-metallic material such as glass or quartz. Alternatively, the grooves 1d can be formed directly in the wall of the mixing element 1 in quartz, as shown for example in the figure 5d .If the brazing element is transparent, its outer surface can be coated with a film that reflects the appropriate wavelengths, particularly the UV light used to treat liquids. This reflective film can be perforated at the points where light is emitted, allowing it to reach the liquids passing through the brazing element. 1. The openings can be simple windows or a linear opening extending over a substantial length of the mixing element. 1, corresponding, for example, to the length of a UV LED strip arranged along the mixing element 1.The reflective film thus arranged concentrates UV radiation onto the fluid flowing through the mixing element 1, thereby improving its efficiency. Alternatively, the reflective film can be placed on an internal wall of the irradiation module to concentrate the light radiation onto the liquid. Such a film can be made of or comprise polymers that reflect the wavelengths used, such as Teflon or PTFE. Other equivalent polymers can be selected, either in combination with or as a replacement for PTFE.

[0040] In order to further increase the efficiency of the irradiation, the grooves 1d They can be coated with a reflective film, either identical to Teflon or of a different nature, thus allowing the deepest liquid layers to be irradiated within the flow of the treated liquid. The grooves 1dalternatively, they can be made entirely of a reflective polymer.

[0041] According to a preferred arrangement, the grooves 1d are arranged on a central section of length I, of the mixing element 1, for example, over two-thirds, or three-quarters, of its total length L. According to such an arrangement, the terminal parts of the mixing element 1 are free of all grooves 1d.

[0042] The device according to the present invention comprises at least one magnetic device 2, preferably 2 magnetic devices 2. Magnetic devices 2 each contain at least one permanent magnet 2a, including a north pole n and a south pole s. A permanent magnet 2a can be circular and surround the mixing element 1.It can alternatively take the form of two hemispheres or several arcs of segments arranged around the mixing element. 1, or it may take the form of a parallelepiped positioned along the mixing element 1. A magnetic device 2 can group several permanent magnets 2a regardless of their shape. In the case of permanent magnets 2a are parallelepiped in shape, their south poles s and north n can be placed at each of their ends. Alternatively, the south poles s and north poles can be distributed along two opposite lengths of the parallelepiped. Regardless of the distribution of their south and north poles, permanent magnets 2a parallelepipeds can be arranged parallel to the mixing element 1,that is to say, so that their length is oriented along the longitudinal axis of the mixing element 1, or perpendicular to the mixing element 1. Several parallelepiped magnets can thus be distributed around the stirring element. 1 and constitute a magnetic device 2.

[0043] Alternatively, permanent magnets 2a They can be circular, either in the form of a disk or in the form of rings. When they are in the form of a ring, their south-north polarization can be radial. Such polarization results from a distribution of the south poles s and north of the permanent magnet 2a on the inner and outer faces of the ring. According to this configuration, the magnetic field from the permanent magnet 2a will be directed perpendicularly to the direction of fluid flow F to be processed in the mixing element 1.Several circular permanent magnets with radial polarization can be grouped together within a magnetic device 2. There figure 3c diagram an example of a magnetic device implementation 2 including permanent magnets 2a whose polarization is axial. Permanent magnets 2a In this configuration, they can be separated by a metallic intermediary element. El. The metallic interlayer El can be inserted between two permanent magnets 2a contiguous, or between groups of permanent magnets 2a. Within a group of permanent magnets 2a In radially polarized magnets, adjacent magnets can have opposite polarities. Groups of permanent magnets 2amay comprise 2 or more magnets, such as 4, 6, 8, or 10 radially polarized permanent magnets. In one particular embodiment, the magnetic device 2 may comprise 2 groups of 8 permanent magnets. 2a radially polarized, separated by an intermediate metallic element El.

[0044] An axial polarization of the circular magnet 2a is obtained when the south and north poles are distributed on opposite lateral surfaces of the ring. According to this arrangement, the magnetic field emanating from the permanent magnets 2a will be oriented substantially parallel to the direction of fluid flow F in the mixing element 1. Several permanent magnets 2a Circular magnets with axial polarization can be grouped together within a magnetic device 2. Permanent magnets can be found within the same magnetic device. 2,in direct contact, or separated by a spacer E. The spacer E It can be of variable thickness. For example, it can correspond to the thickness of a permanent magnet. 2a or two permanent magnets 2a, or more than two permanent magnets. The spacer E can be inserted between two permanent magnets 2a or between two groups of permanent magnets 2a. The spacer E is preferably made of a non-metallic material. Spacer E, for example, can be made of a polymer material. Each of the groups of permanent magnets 2a can contain 2 or more permanent magnets 2a, such as 3 or 4 or more permanent magnets 2a. An example of a magnetic device is illustrated at the figure 3b A magnetic device 2 This arrangement includes four pairs of axially polarized permanent magnets and three spacers E,each spacer E being positioned between two pairs of permanent magnets 2a. Permanent magnets 2a are matched so that the south pole of one of the two permanent magnets 2a either opposite the north pole of the permanent magnet to which it is paired.

[0045] A magnetic device 2 According to the present invention, circular magnets can be grouped together. 2a whose polarizations are axial and radial. In the case of the same magnetic device 2 groups together several permanent magnets 2a of axial polarization, the south-north orientation of permanent magnets 2a can be identical or reversed. In the case of the same magnetic device 2 groups together several permanent magnets 2a of radial polarization, the south-north orientation of permanent magnets 2a can be identical or reversed.

[0046] Permanent magnets 2a, within the same magnetic device 2, they can be placed side by side or separated by an intervening metallic element El. Such an intervening metallic element can notably be of a ferric type, such as ferric stainless steel, and influence the magnetic field emanating from permanent magnets. 2a to which it is associated. In particular, in the case of permanent magnets 2a circular with radial polarity, the intercalated metallic element El can orient the magnetic field other than perpendicular to the direction of fluid flow F in the mixing element 1. In this case, the magnetic field resulting from such an assembly can be oblique or even parallel to the direction of fluid flow. F in the mixing element 1.

[0047] According to a privileged arrangement, a magnetic device 2The present invention comprises a set of several permanent magnets 2a radially polarized circulars, combined with at least one intermediate metallic element El. In particular, such a magnetic device 2 It contains two pairs of permanent magnets. 2a radially polarized circular elements separated by an intervening metallic element El. Preferably within a pair of magnets 2a, The south-north polarities are reversed. In other words, the south pole of one of the permanent magnets 2a is positioned on the inner face of the ring while the south pole of the permanent magnet 2a The adjacent part is positioned on the outer face of the ring. The pairs of permanent magnets 2a are preferably arranged symmetrically on either side of the intermediate metal element El.According to such a symmetrical arrangement, the circular permanent magnets located at both ends of the magnetic device 2 are both polarized in the same way, their south pole being located on the inner face of the ring or, conversely, on their outer face.

[0048] According to a specific arrangement, the two magnetic devices 2 can be identical to each other, in the sense that the arrangement of the permanent magnets 2a is the same in each of the two magnetic devices 2. According to another arrangement, preferred within the framework of the present invention, the two magnetic devices 2 are reversed in the sense that the arrangement of the permanent magnets 2a is inverted by a magnetic device 2 to the other.

[0049] According to a preferred configuration, the D treatment device comprises 2 magnetic devices 2each positioned at one end of the mixing element 1. They are advantageously arranged around a portion of the mixing element. 1 devoid of grooves 1d. In this way, the fluid to be treated F, when it passes through the mixing element 1, passes through a magnetic field before crossing the section of the mixing element 1 equipped with grooves 1d. It then passes through a second magnetic field after passing through the section of the mixing element. 1 equipped with grooves 1d, just before being picked up at the exit S of the mixing element 1.

[0050] The distance I corresponds to the cross-section of the mixing element 1 lined with fluting 1d can vary depending on the strength of the generated magnetic fields. For example, the length lcan be determined in such a way that the magnetic fields generated by the magnetic devices 2 do not interact. Alternatively, the length I may be short enough for the magnetic fields generated by the magnetic devices 2 interact. More generally, the degree of interaction between magnetic fields depends on the length I The interaction of magnetic fields can, in this case, be attraction or repulsion, depending on the arrangement of the permanent magnets. 2a within magnetic devices 2.

[0051] According to a preferred arrangement of the invention, the length I is determined in such a way as to allow the interaction of magnetic fields generated by magnetic devices 2. Advantageously, the magnetic interaction is of the repulsive type.

[0052] The permanent lovers 2aThe magnets can be of different types depending on the desired properties. For example, high-temperature resistant magnets may be recommended to allow the device to be washed at high temperatures such as 80 or 100 degrees Celsius, or steam washed at temperatures exceeding 100 degrees Celsius. Ferric magnets can be advantageously used, which may include elements other than iron, such as copper, aluminum, or nickel. Alternatively, samarium or cadmium-based magnets may be employed. Depending on the specific requirements of the present invention, permanent magnets 2a Neodymium-based magnets can be chosen. Magnets containing cobalt, boron, or other elements are considered alternatively.

[0053] Magnetic devices 2 may include permanent magnets 2a of different types or of the same type.

[0054] Optionally, one or more magnetic devices 2 Additional components can be arranged around a portion of the mixing element. 1 lined with fluting 1d. In this way, the fluid to be treated F is also subject to the concomitant effect of the grooves 1d and a magnetic field. The magnetic device(s) 2a Additional components may be identical or different from the terminal magnetic devices. They may, in particular, consist of permanent magnets. 2a parallelepiped in shape.

[0055] According to a preferred configuration, the processing device D includes 2 magnetic devices 2 each positioned at one end of the mixing element 1, around a portion of the mixing element 1 devoid of grooves 1d. The first magnetic device 2,positioned before the portion of the mixing element 1 Equipped with 1d grooves, includes a set of permanent magnets 2a of axial polarization, and the second magnetic device 2, positioned after the portion of the mixing element 1 equipped with grooves 1d, includes an array of radially polarized 2a permanent magnets. Preferably, the arrangement is that described by the figures 3a, 3b and 3c The first magnetic device 2 includes 4 groups of permanent magnets 2a of axial polarization, the groups of permanent magnets 2a being separated by spacers E. The second magnetic device 2 includes two groups of permanent magnets 2a radially polarized, separated by a metallic interlayer El.

[0056] According to a particular arrangement, the mixing element 1may include more than one section lined with grooves 1d, which may or may not be separated by a magnetic device 2a.

[0057] Magnetic devices 2 can be surrounded by magnetic shielding, such as a layer of ferrous steel 2b. According to a specific arrangement, the magnetic shielding layer extends along the entire length of the mixing element. 1. According to an alternative provision, only magnetic devices 2 are covered with a layer of magnetic shielding 2b.

[0058] Magnetic devices 2 and their magnetic shielding 2b are advantageously coated with a protective polymer layer, such as a plastic material 2c.

[0059] According to one aspect of the present invention, the assembly consisting of the mixing element 1 and magnetic devices 2,accompanied by their protective layers 2c and magnetic shielding 2b, is encapsulated totally or partially in an austenitic stainless steel enclosure 3. Such an enclosure can, for example, take the form of a tube. 3a encompassing magnetic devices 2 over a length equal to or less than the length of the mixing element 1. The ends of the tube 3a constituting the enclosure 3 can be closed using austenitic stainless steel sleeves 3b.

[0060] The enclosure can then be insulated in a gel-foam suitable for magnetic devices.

[0061] According to an advantageous provision, the mixing element 1may be surrounded, along its entire length or only a portion of it, by a heating or cooling system, not shown. One or more supply lines may be provided to allow the supply of other fluids within the mixing element. 1, either sequentially or simultaneously to perform mixing. Other permissible fluids may be liquids or gases. One or more purge lines may also be provided along the mixing element. 1, in particular to allow for total or partial degassing of the treated fluids.

[0062] Advantageously, the feed pressure of the fluids to be treated can be regulated upstream of the feed. Mixing can then be carried out at atmospheric pressure or at a pressure higher than atmospheric pressure, such as 2, 3, 10, or 50 bar. Alternatively, a vacuum pump can be included to create a vacuum in the mixing element. 1.

[0063] The treatment device D According to the present invention, it may further comprise a UV irradiation module 3 illustrated at figure 6This process eliminates or reduces microorganisms present in the liquid being treated. Such microorganisms can be pathogenic and pose a risk of poisoning to the consumer. Furthermore, some microorganisms contribute to changes in the liquid, particularly during prolonged storage. Sulfites or other preservatives are often used as germicides, but these can have potentially harmful effects on the consumer. The UV irradiation module 3 This allows for the limitation or complete elimination of the use of germicidal additives in the liquid being treated, particularly sulfites. The liquid can then be treated according to biological or natural standards. The UV irradiation module 3, includes, in particular, at least one UV irradiation source 3a, 3b, 3c, 3d, directed towards the liquid to be treated. The UV irradiation module 3This allows the liquid to be treated continuously as it flows through the mixing element. 1. The wall of the mixing element 1 In this case, it is transparent to UV light so as to be able to irradiate the liquid during its transit through the mixing element. 1. In this case, it can be made of quartz, with a thickness ranging from approximately 2 mm to 50 mm depending on the diameter. d of the mixing element 1, the pressure of the liquid passing through it, and any other parameters. The UV irradiation source(s). 3a, 3b, 3c, 3d can take the form of LEDs or groups of LEDs arranged along the mixing element 1and outside of it. The UV radiation emitted by such UV radiation sources is preferably type C UV, with wavelengths between 100 nm and 280 nm. Other wavelengths or a mixture of several wavelengths may nevertheless be emitted. UV radiation sources 3a, 3b, 3c, 3d can be arranged continuously along the mixing element 1, preferably opposite the grooved sections. Indeed, the grooves 1d, By allowing the division and mixing of liquid streams, they increase their exposure to light irradiation and consequently the effectiveness of the germicidal effect of such irradiation. Furthermore, opaque liquids such as red wine, or even milk, can easily be treated in their entirety thanks to the grooves. 1d of the mixing element 1.Dividing the liquid flow thus makes it possible to limit the size of the treatment device and the duration of the liquid's exposure to UV light. The combined effect of the grooves 1d UV irradiation offers an advantageous synergy in liquid treatment. A reflective film, as described above, can be fitted to the UV irradiation module. 3 and / or the mixing element 1.

[0064] The mixing element 1 includes an internal surface 11a and an external surface 11b, which can both be completely cylindrical and concentric. Alternatively, either of the internal surfaces 11a and external 11b, or both, may include one or more recesses 11c ( figure 7 Such recesses can be longitudinal and extend along the entire length of the mixing element. 1or only part of its length. Alternatively, or in addition, recesses 11c Circular or elliptical shapes can be incorporated throughout the surfaces of the mixing element. 1. Such hollows 11c have the distinctive feature of forming concave curves on the walls of the mixing element. 1, which has the effect of concentrating UV radiation towards the inside of the mixing element 1, or at least to limit their thinking outwards.

[0065] The UV irradiation module 3 It can be used for the photolysis of undesirable compounds in the beverage. Thujone, for example, can be degraded to keep its proportions below regulatory thresholds or to degrade it completely.

[0066] The UV irradiation module 3 can advantageously be arranged between 2 magnetic devices 2.When more than two magnetic devices 2 are arranged along the mixing element 1, several UV irradiation modules 3 can be inserted. So as to limit the bulk of the treatment device D, the UV irradiation module(s) 3 can be integrated into the magnetic shielding or included within its enclosure.

[0067] It is therefore possible to synergize the mixing of the liquid being treated by the grooves with both the magnetic field and UV irradiation. In this way, the effects of UV irradiation are maximized while maintaining a compact size for the treatment device. It is noteworthy that several treatment steps are carried out simultaneously. In particular, the steps for treating organoleptic and germicidal properties are performed concurrently.

[0068] The treatment device Dmay also include an analysis module 4 online monitoring allows for real-time tracking of several parameters. One or more of the selected physicochemical parameters—pH, redox potential, conductivity, dissolved oxygen and / or CO2 levels, and turbidity—can be monitored continuously or in batches. Analysis of microorganisms present in the treated liquid is also possible, either in addition to or instead of the physicochemical analysis, depending on the requirements. Preferably, the analysis is performed continuously. A bypass line 40 can be connected to the mixing element 1 or at the outlet of the mixing element 1 to conduct a portion of the treated liquid into an analytical device 5. The bypass pipe 40 may be equipped with a filter 42 and possibly a bypass loop 40ballowing the liquid to be analyzed to pass either through or outside the filter 42. One or more valves 41a, 41b can be included in the analysis module 4 to open or close the pipes. The liquid to be analyzed is conveyed to the analysis device. 5 to determine one or more of its physico-chemical or biological parameters.

[0069] The analysis device 5 may be a flow cytometry (FCM) device or any other analytical device useful for determining online parameters, as well as a combination of measuring devices.

[0070] The treatment device D It can then be used for research, development, or process optimization. It can also enable frequent quality control checks during production.

[0071] The treatment device Dcan be easily adapted to existing systems. For example, it can be adapted to a tangential flow filter or other existing equipment. Furthermore, it offers the possibility of modular modification to existing systems. In this case, the treatment device D may take the form of a basic arrangement including the mixing element 1 and at least one magnetic device 2. It may also include one or more UV irradiation modules 3 and analysis 4, or a combination of both.

[0073] Step a) can be carried out using a pump P. The fluid can be supplied at ambient pressure or at a different pressure. The temperature of the fluid to be treated can also, or alternatively, be controlled upstream of the supply. The magnetic field encountered during step b) is generated by a magnetic device. 2 according to the invention described above. Steps b) and c) are preferably successive. However, they may be concurrent. The terms "passing through a magnetic field" or "passing the fluid through a magnetic field" essentially refer to the passage of the fluid through a magnetic device 2, as described above.

[0074] Steps b) and c) may optionally be repeated several times, either by using an open-loop device or by means of several grooved sections separated by several magnetic devices. 2.

[0075] The treatment process according to the present invention can be carried out on the entire tank or only on a portion of it. The storage tank can be provided with two outlets for this purpose, only one of which is connected to the treatment device. D of the present invention.
