    Invention Patent Descriptive Report for PORTION CAPSULE TO PRODUCE A TEA DRINK. PREVIOUS TECHNIQUE [001] The present invention relates to a beverage substance for producing a tea beverage, wherein the beverage substance is provided to be stored in a serving capsule and to be prepared in the serving capsule by means of hot water being introduced under pressure into the serving capsule, and wherein the substance of the beverage is substantially granulated and comprises tea at least in part.
    [002] Such beverage substances are generally known and are often filled in portion capsules. For example, FR 2 556 323 A1 makes known a portion capsule for producing a beverage that has a cylindrical base element or substantially in the shape of a truncated cone, that has a hollow space and a membrane that closes the hollow space, an element of filter being disposed within the hollow space, said filter dividing the hollow space into a first region to accommodate the beverage substance and a second region to accommodate an extract of the beverage. The substance of the drink, in this case, however, comprises a ground coffee. The serving capsule is consequently used to produce a coffee drink. To produce the beverage, the portion capsule is arranged in a preparation chamber of a machine with preparation chamber in which the membrane is perforated and an extraction liquid, in particular hot water, is placed within the first region. The beverage substance is passed through the extraction liquid during an extraction operation, such that the beverage extract, in this case a coffee drink, is formed that passes directly through the filter openings in the filter element into the second region of the hollow space. The sieve function of the filter element prevents the substance of the drink

    2/18 also enter the second region. In the preparation chamber, a lower region of the portion capsule is also perforated, such that the beverage extract is able to leave the portion capsule and, where applicable, enter a beverage container such as, for example, a cup of coffee.
    [003] Furthermore, it is known to use these types of serving capsules filled with a tea substance in order to produce a tea drink in an analogous manner using the machine with preparation chamber. In this context, however, the problem arises that a high quality tea drink has to be prepared in a comparatively short preparation time. The user of such machines with a preparation chamber receives a finished drink within a maximum interval of 1 to 1.5 minutes. In addition, well-known brewing machines can, as a rule, deliver hot boiling water to the portion capsule for a maximum of 60 to 90 seconds. In order to produce a cup of tea, the boiling water has to be pumped comparatively quickly through the capsule volume of the portion. The interaction time between the tea substance and the boiling water is therefore comparatively short and in particular clearly shorter than in the case of a classic or manual preparation operation for a classic tea drink. The quality of the tea drink produced in a machine with a brewing chamber using a portion capsule is therefore comparatively poor.
    [004] Consequently, it is the aim of the present invention to make a beverage substance available, as a result of which the disadvantages of the prior art are avoided and a more efficient, faster and more reliable preparation operation for the production of a beverage. tea is obtained.
    DESCRIPTION OF THE INVENTION
    Petition 870190030900, of 03/29/2019, p. 4/29
    3/18 [005] The goal is achieved with a beverage substance for the production of a tea beverage, in which the beverage substance is supplied to be stored in a serving capsule and to be prepared in the serving capsule by means of introducing hot water under pressure into the portion capsule, in which the substance of the beverage is substantially particulate and comprises tea at least in part and in which the substance of the beverage has an average particle size between 500 micrometers and 1500 micrometers.
    [006] The advantage of the beverage substance as claimed in the invention compared to the prior art is that a clearly more efficient, faster and cleaner preparation of the beverage substance becomes possible. On the one hand, the particle sizes are selected small in such a way that the substance of the drink has a large surface and, as a result, even in a comparatively short preparation time, it is possible to prepare the tea efficiently with good flavor development and aroma. On the other hand, particle sizes are selected large in such a way that the beverage substrate can be filtered out of the tea beverage generated in a simple manner and, consequently, the tea beverage prepared for a consumer is not contaminated by the beverage substrate. nor is its flavor impaired. The term 'particulate' in particular in the sense of the present invention means the same as 'granular'. The average particle size comprises, in particular, the D43 value (also referred to as the average volumetric particle diameter) when the substance of the beverage is measured using the Malvern laser diffraction method. The Malvern Mastersizer 3000 with a dispersive pressure of 0.4 MPa (4 bar), dry dispersion Aero S and a feed speed between 60 and 90 has been used for this type of measurement.
    [007] As claimed in a preferred modality of
    Petition 870190030900, of 03/29/2019, p. 5/29
    4/18 of the present invention, it is provided that the beverage substance has an average D43 particle size between 650 micrometers and 1320 micrometers. In a preferred manner, the beverage substance has a proportion of particles with a particle size greater than 500 micrometers that is between 40 percent and 90 percent and is preferably between 50 and 80 percent. In a particularly preferred manner, the beverage substance has a proportion of particles with a particle size less than 100 micrometers that is less than 10 percent and is preferably less than 8 percent. It has been demonstrated in a way that is unexpected and surprising to the expert that the substance of the drink with such a particle distribution exhibits excellent extraction behavior. In particular, efficient extraction and a satisfactory aroma are obtained where the amount of tea raw material used is less than in the prior art. In particular, an extract content between 1 and 3 percent is obtained as a result. The extract content specifies the percentage amount of dry substance extracted. In this respect, the amount of substances from the plant parts released during preparation that remain behind as a solid after drying in the drying cabinet is divided by the amount of plant parts present in the capsule. The result is the content of the extract as a percentage. [008] As claimed in a preferred embodiment of the present invention, it is provided that the substance of the beverage has a specific swelling capacity between 1.5 and 3 and in particular between 1.0 and 2.6. The swelling capacity comprises, in particular, the specific swelling capacity and is calculated as a quotient of the volume of the dried plant parts and the volume of the swollen plant parts after the preparation process. The defined swelling capacity advantageously enables optimum preparation efficiency
    Petition 870190030900, of 03/29/2019, p. 6/29
    5/18 of the beverage substance in the serving capsule. In particular, as a result, during the brewing operation, water absorption of the beverage particles is carried out, which ensures optimal development of the tea's aroma.
    [009] As claimed in a preferred embodiment of the present invention, the substance of the beverage is provided to be thermally preheated to reduce germs. Herbal teas are subjected to a very unstable germ load. Priority attention has been directed to enterobacteria (salmonella, coliforms), as these can result in stomach breakdowns to very serious and even fatal diseases. In an advantageous manner, the substance of the drink is consequently pre-heat treated in order to reduce enterobacteria, but also yeasts and fungi. Even if the water is not boiling when it flows into the capsule, it is therefore ensured that the few germs still present are eliminated and, as a result, it is possible to produce a hygienically perfect drink.
    [0010] The object of the present invention is also achieved with a beverage substance to produce a tea beverage, wherein the beverage substance is provided to be stored in a portion capsule and to be prepared in the portion capsule by means of introducing hot water under pressure into the portion capsule, in which the substance of the beverage is substantially granulated and comprises tea at least in part and in which at least 90 percent of the substance of the beverage has an average particle size between 0.1 and 2 millimeters.
    [0011] In a preferred manner, it is provided that at least 90 percent of the substance in the drink has an average particle size between 1 and 2 millimeters. Filtering the beverage substrate of the tea beverage is particularly efficient in this respect, since almost all
    Petition 870190030900, of 03/29/2019, p. 7/29
    6/18 particles are trapped in the filter and, at the same time, however, the individual openings of the filter are prevented from being blocked by particles that are very small. In terms of the present invention, the percentage specifications refer, in particular, to the mass percentage of the particles, that is, that those particles of the beverage substance that have an average particle size between 0.1 and 2 millimeters make up at least 90 percent of the mass of the beverage substance. In terms of the present invention, the particle size comprises, in particular, the average particle diameter of the beverage substance. The latter is preferably measured using a sieve analysis where the beverage substance is sieved, for example, using a sieve tower that is produced from several test sieves that are stacked on top of each other. The mesh width of the individual test screens, in this case, decreases from the top to the bottom. To perform the sieve analysis, the substance of the drink is deposited on the uppermost test sieve and is then exposed to a defined stirring motion. The grain size distribution of the beverage substance is determined by weighing the residues on the individual test screens. To produce the substance of the beverage, tea leaves, in particular after the wilting process, are crushed, cut and / or rolled (for example, by means of a mechanical CTC process) in order to achieve the desired particle size mentioned above. or the particle size distribution. It is additionally conceivable that the wilted tea leaves are chopped, cut and crushed or the like. The beverage substance is produced, for example, using the method called CTC, the particle size distribution is then measured using the aforementioned sieve analysis method and a decision is made through the analysis results obtained as to whether steps Additional size reduction is required or if the
    Petition 870190030900, of 03/29/2019, p. 8/29
    7/18 desired particle size distribution is already present.
    [0012] Advantageous developments and further developments of the invention can be found in the embodiments, as well as in the description with reference to the drawings.
    [0013] As claimed in a preferred embodiment of the present invention, it is provided that the substance of the beverage includes a defoaming feature. In an advantageous manner, a very strong foaming of the beverage substance during or after the brewing operation is prevented by the defoaming feature. In particular when leaving the capsule of the portion, the tea drink is strongly rotated, as a result of which large foam bubbles are formed. The latter make it difficult to fill the tea drink in an appropriate manner in a receiving container, such as a cup or mug. The defoaming feature comprises, in particular, hydrophobic plant constituents. In a preferred embodiment, the defoamer feature comprises a vegetable oil. The vegetable oil is preferably sprinkled over a tea bean which is then filled into the serving capsule. It has been demonstrated in a surprising and unpredictable way that with a maximum proportion of antifoam resource of 5 percent, in a preferred way, a maximum of 2 percent and in a particularly preferred way a maximum of 1.5 percent of the overall mass of the substance of the drink, foaming is effectively prevented and, at the same time, there is enough tea substance in the substance of the drink to generate a high quality tea drink. Along with the substance substances described above, the substance of the beverage may also include flavoring and coloring components, such as, for example, sugar, caramel coloring, natural vegetable coloring, dry aqueous fruit extracts, spices and herbs, extracts oils and seasoning extract mixtures, herbs, citrus peel and others
    Petition 870190030900, of 03/29/2019, p. 9/29
    8/18 plants and plant parts, aroma substances for rounding, typification and standardization or similar.
    [0014] Said substances of content, after preparation, produce a tea drink that corresponds with the drink traditionally prepared in all characteristics, such as aroma, flavor, color and appearance.
    [0015] As claimed in a preferred embodiment of the present invention, it is provided that the beverage substance comprises green tea and / or black tea. In particular, the substance of the beverage generally comprises substantially between 2 and 4 grams, in a preferred manner between 2.5 and 3.5 grams and in a particularly preferred manner substantially 3 grams of green tea and / or black tea.
    [0016] A further object of the present invention is a portion capsule for producing a tea beverage, said portion capsule having a substantially closed container that is at least partially filled with a preparation substance which is provided for preparation, in that the portion capsule can be inserted into a machine with a preparation chamber for preparing the preparation substance and wherein the preparation substance comprises a beverage substance as claimed in the invention. The advantage of the portion capsule compared to the prior art is that it is possible to prepare the substance of the beverage that is located in the portion capsule in a clearly more efficient, faster and cleaner manner. The portion capsule preferably has a filter element which, in a particularly preferred manner, has filter openings having an average bore diameter between 0.01 and 1 millimeter. The advantage of this compared to the prior art is that there is no contamination of the tea drink to be produced by the particles of the substance of the drink, at the same time, a behavior of
    Petition 870190030900, of 03/29/2019, p. 10/29
    9/18 more efficient preparation of the substance of the drink being achieved. The high level of efficiency of the brewing operation additionally enables, in an advantageous manner, a reduction in the quantity of the required drink substance, as well as a high brewing speed, as a result of which the duration of the drink preparation procedure is reduced . It has been shown in a surprising and unpredictable way that, in particular, with a substance in the drink where at least 90 percent of the substance in the drink has an average particle size between 0.1 and 2 millimeters, combined with a filter element that has filter openings with an average bore diameter between 0.01 and 1 millimeter, an optimum ratio between the efficiency of the preparation and the speed of the preparation on the one hand and the filtration rate on the other is achieved.
    [0017] As an alternative to this, it is conceivable that the filter element comprises a filter felt, whereby a similarly optimal result can be achieved. The filter felt material preferably comprises polyester, such that cost-effective production and a high degree of tear resistance can be achieved. The filter felt in particular has a weight per unit area between 100 and 2000 grams per square meter, in a preferred way between 400 and 900 grams per square meter, in a particularly preferred way between 600 and 700 per square meter and in a very particularly preferred way of substantially 650 grams per square meter. In addition, the filter felt, at right angles to its main extension plane, has, in particular, a thickness that is between
    1.5 and 5.0 millimeters, in a preferred manner between 2 and 4 millimeters and in a particularly preferred manner is substantially 2.8 millimeters. As an option, the filter felt is carried out in such a way that, at a pressure of 200 Pa, the filter felt has an air permeability between 100 and 1000 L / (dm 2 .min), in a way
    Petition 870190030900, of 03/29/2019, p. 11/29
    10/18 is preferred between 200 and 300 L / (dm 2 .min) and in a preferred manner of substantially 250 L / (dm 2 .min). The defined filter felt makes it possible, in an advantageous way, a fast, efficient and aromatic extraction of the substance of the drink without, in this aspect, the removal of the particles of the substance of the drink from the portion capsule and consequently the drink becomes contaminated. As an alternative to this, it is also conceivable that the filter element comprises a filter fleece.
    [0018] The closed container preferably has a substantially cone-shaped base element with a closed bottom which is sealed on its far side from the bottom with a cover sheet, in which a hollow space to accommodate the preparation substance is realized between the bottom and the cover sheet. In an advantageous manner, the portion capsule as claimed in the invention can therefore be used in traditional preparation chamber machines.
    [0019] An additional object of the present invention is a method for producing a tea drink with a serving capsule in which, in a first step of the method, the serving capsule is inserted into a preparation chamber of a machine with a serving chamber. preparation in which, in a second stage of the method, boiling water is introduced into the portion capsule and the preparation substance is prepared by means of the boiling water to produce the tea beverage and in which, in a third stage of the method, the beverage of the tea is discharged from the serving capsule. By using the portion capsule as claimed in the invention, a tea beverage, which is of superior quality compared to the prior art, is produced in a comparatively short preparation time without any substrate residues from the beverage.
    [0020] It was shown that the mentioned advantages are achieved in
    Petition 870190030900, of 03/29/2019, p. 12/29
    11/18 particularly when the extract content is maintained between 1 and 50 percent, in a preferred manner between 1 and 10 percent and, in a particularly preferred manner, between 1 and 3 percent. The extract content is maintained, in particular, by an average particle size D43 of the beverage substance being provided between 500 micrometers and 1500 micrometers and, in a preferred manner, between 650 micrometers and 1320 micrometers and / or the substance of the beverage being provided with a proportion of particles with a particle size greater than 500 micrometers that is between 40 percent and 90 percent and preferably between 50 and 80 percent and / or the substance of the beverage being provided with a proportion of particles with a particle size less than 100 micrometers which is less than 10 percent and preferably less than 8 percent.
    [0021] Exemplary modalities of the invention are shown in the figures and are explained in more detail in the following description. The figures are described purely as an example and do not limit the general concepts of the invention.

    12/18 [0025] Figure 4 shows a schematic side view of a sectional design of the portion capsule as claimed in an additional exemplary embodiment of the present invention during a preparation operation.
    MODALITIES OF THE INVENTION [0026] Figure 1 shows a schematic side view of a sectional design of a capsule of portion 1 as claimed in a first embodiment of the present invention, the capsule of portion 1 having a substantially cone-shaped base element 2 which is made in the manner of a mug and surrounds a hollow space 3. The hollow space 3 is closed by a cover sheet 4 in the form of a membrane. The base element 2 comprises, in particular, a malleable or rigid plastic material. The cover sheet 4 preferably comprises a thin plastic material or aluminum foil. The base element 2 has a circumferential fixing flange 20 in the region of the membrane 4, the membrane 4 being positively joined, in particular welded or glued, to the fixing flange 20. A filter element 5 is arranged within the base element 2 which is produced from a thermoplastic plastic material, for example, polypropylene. The filter element 5 divides the hollow space 3 into a first region 6 and a second region 7. The first region 6 is provided to accommodate a substance of the powdered beverage 10 which is only schematically illustrated in the figures for the sake of clarity. The substance of the beverage 10 comprises granulated tea. The substance of the beverage 10 is filled, for example, in the first region 6 and is then compacted before the hollow space 3 is closed by the cover sheet 4. The second region 7 serves to accommodate and, in particular, to collect a tea drink (not shown) during a preparation operation of the portion 1 capsule. The portion 1 capsule is provided for the purpose of being inserted into a preparation chamber 12 of a machine with
    Petition 870190030900, of 03/29/2019, p. 14/29
    13/18 preparation chamber (not shown in figure 1), in which a preparation liquid (for example, hot water) is preferably supplied at high pressure to the first region 6. Said preparation liquid interacts with the substance of the drink 10, such that a tea drink is formed. The filter element 5 has a plurality of filter openings 8 and functions as a filter for the beverage, as a result of which particles of the beverage substance 10 are filtered from the produced beverage. The tea beverage, in this respect, passes through the openings of the filter 8 into the second region 7, while no particle of the beverage substrate 10 enters the second region 7. The second region 7 is defined by a lower region of the base element 2 which is perforated in the preparation chamber 12, for example, by a drilling mandrel of the machine with preparation chamber in order to produce an outlet opening for the drink. As an alternative to this, it is conceivable that an outlet opening is automatically formed in the base region under the pressure of the preparation liquid and / or that an outlet opening or an outlet valve is already implemented in the lower region. The outlet opening is closed, for example, by means of a sealing sheet that is removable by hand and is removed manually by a user before inserting the capsule of portion 1 into the machine with preparation chamber. The substance of the beverage 10 is substantially granulated and comprises at least in part green tea and / or black tea. However, it is also conceivable that the substance of beverage 10 comprises any other type or combination of commercially available teas, such as, for example, fruit tea, herbal tea, mint tea, chamomile tea, rose tea and so on. against. It would also be conceivable that the substance of the beverage 10 comprises an iced tea granulate. The grain size distribution of the beverage substrate 10 is additionally selected in such a way that at least 90 per
    Petition 870190030900, of 03/29/2019, p. 15/29
    14/18 percent of the substance in beverage 10 has an average particle size between 0.1 and 2 millimeters. The grain size distribution, in this case, is matched in particular with the average diameter of the filter openings 8 which comprises substantially between 0.01 and 1 millimeter. The ratio between the grain size distribution of the beverage substance 10 and the diameter and cross section of the individual filter openings 8, in this case, is selected in such a way that almost no particle of the beverage substance 10 passes from the first to the second region 6, 7 and at the same time a preparation of the substance of the drink 10 as fast and efficient as possible is obtained. The general mass of the substance of the beverage 10 in the capsule of portion 1 preferably comprises substantially 3 grams. The beverage substance 10 additionally has a defoaming feature which is, in particular, granular and comprises at least one oil. The defoaming feature, in this case, preferably comprises a maximum proportion of 1.5 percent of the overall mass of the substance of the beverage 10. It is conceivable that the substance of the beverage 10 is thermally pretreated to reduce germs.
    [0027] As an option or as an alternative to this, it is provided that the substance of the beverage 10, when it is measured using the Malvern laser diffraction method (for example, by means of a Malvern Mastersizer 3000 with dispersive pressure of 0 , 4 MPa (4 bar), Aero S dry dispersion and feed rate between 60 and 90) has an average D4.3 particle size between 650 micrometers and 1320 micrometers. In addition, the substance of the beverage 10 has a proportion of particles with a particle size greater than 500 micrometers which is between 50 and 80 percent and a proportion of particles with a particle size less than 100 micrometers which is less than that 8 percent. The specific swelling capacity of the substance of the beverage 10 is between 1.0 and 2.6.
    Petition 870190030900, of 03/29/2019, p. 16/29
    15/18 [0028] Figure 2 shows a schematic side view of a sectional drawing of the capsule of portion 1 described by means of figure 1 during a preparation operation. The capsule of portion 1, in this case, is arranged in a preparation chamber 12 of a machine with preparation chamber which can be, for example, a coffee machine for preparing capsules of the coffee portion. The preparation chamber 12 comprises a receiving element 13 for receiving the capsule of the portion 1 and a sealing element 14 for sealing the receiving element 13. The preparation chamber 12 is movable by axially displacing the sealing element 14 with respect to the element between a loading position (not shown) and a preparation position shown in figure 2. In the loading position, the receiving element 13 and the sealing element 14 are spaced apart from each other along the axial direction 100 , such that the capsule of the portion 1 can be inserted into the preparation chamber 12 or can be arranged along the axial direction 100 between the sealing element 14 and the receiving element 13. The sealing element 14 is then moved along the axial direction 100 towards the receiving element 13, such that the flange 20 is trapped between the edge of the receiving element 13 and the sealing element 14 and consequently a closed preparation chamber 12 is formed. In addition, the receiving element 13 has a mandrel 15 and the sealing element 14 has a plurality of piercing tips 16. When the preparation chamber 12 is closed, the lower region of the capsule of portion 1 is pierced through the mandrel 15 and the cover sheet 4 is perforated by means of the piercing tips 16. The sealing element 14 has a liquid feeding opening 17, through which the liquid of the preparation is fed to the first region 6 of the capsule of the portion 1 in the form pressurized water, hot or cold. Boiling water, in this case, is introduced into the capsule of portion 1 by a
    Petition 870190030900, of 03/29/2019, p. 17/29
    16/18 time period between 60 and 70 seconds. The preparation liquid, in this case, enters the capsule of portion 1 through the drilling holes, which are generated in the cover sheet 4 by means of the drilling tips 16. The liquid of the preparation interacts with the substance of the beverage 10 within the first region 6, as a result of which a tea drink is formed or prepared which passes through the filter openings 8 of the filter element 5 into the second region 7. The tea drink is further directed out of the second region 7 through from the outlet hole, which is generated by means of the mandrel 15 in the lower region and is then supplied to a beverage container (not shown) such as, for example, a cup of tea or mug of tea. In particular, an amount of substantially 200 milliliters of the tea beverage is supplied to the beverage container in a single brewing operation. The content of the extract, in this respect, is in particular between 1 and 3 percent. After the preparation operation has been completed, the sealing element 14 is moved away from the receiving element 13 again, such that the used portion capsule 1 can be removed or automatically ejected and the machine with preparation chamber, where applicable, can be filled with a new capsule of portion 1.
    [0029] Figure 3 shows a schematic side view of a sectional drawing of a capsule of portion 1 having a substance of the beverage 10 as claimed in an additional exemplary embodiment of the present invention, the capsule of portion 1 being substantially the same as the capsule of the portion 1 shown in figure 1 and the only difference being that the filter element 5 is made as a filter felt. The substance of the drink 10 corresponds, in particular, with the substance of the drink 10 described together with figures 1 and 2.
    [0030] The filter felt material preferably comprises polyester. The filter felt has a weight per unit area between 600 and 700
    Petition 870190030900, of 03/29/2019, p. 18/29
    17/18 grams per square meter and, in particular, substantially 650 grams per square meter. The thickness of the filter felt at right angles to its main extension plane is substantially 2.8 mm. At a pressure of 200 Pa, the filter felt preferably has an air permeability of substantially 250 L / dm 2 .min.
    [0031] Figure 4 shows a schematic side view of a sectional drawing of the capsule of portion 1 described by means of figure 3 during a preparation operation, the mandrel penetrating the bottom of the capsule from below - similar to what happens in the figure 2. In the present example, however, the end of the mandrel enters the filter felt, such that the drink is able to leave the capsule of portion 1. The content of the extract, in this respect, is also in particular between 1 and 3 per cent. It is also conceivable that the mandrel tip penetrates the filter felt completely and / or that the filter felt is raised slightly in the region of the mandrel tip. An efficient flow of the drink is made possible through the transverse flow inside the filter felt (parallel to the plane of the main extension of the filter felt), the individual particles of the substance of the drink being filtered through the filter felt and consequently not contaminating the drink when she leaves.
