Description

Filter element for portioned capsules for preparing drinks

The invention relates to portioned capsules used in special devices for preparing beverages, for example coffee, tea, broth, additionally containing functional ingredients such as vitamins, biologically active substances, macro- and microminerals, and in particular to the filter element of these capsules.

The current trend is to enrich the diet with functional ingredients. Particularly suitable for the introduction of functional ingredients are drinks consumed daily, for example coffee, tea. Capsules for the preparation of one portion of the drink represent the possibility of introducing into them a predetermined amount of a functional ingredient, which represents a substantial part of the required daily dose.

By simply mixing the beverage preparation ingredient with the functional ingredient, a substantial portion of the functional ingredient can be adsorbed on the beverage preparation ingredient particles, for example, ground coffee particles.

Known technical solutions in which the ingredient for the preparation of the drink and the functional ingredient is introduced into the capsule separately. For example, a portioned capsule for making coffee is known [International Application WO2016159835, publ. 10/06/2016], in which an additional chamber is made for placing a functional ingredient. The capsule is designed in such a way that water first enters the part of the capsule where the coffee powder is placed, and then the coffee solution enters the chamber with the functional ingredient, and the enriched coffee is discharged from the capsule. However, there are several problems with this capsule. This approach can only be implemented on capsules having an additional chamber, and the standard is not suitable for introducing functional ingredients equipment. The preset amounts of functional ingredients introduced into the capsules are small, often on the order of milligrams or tens of milligrams; therefore, their exact dosage is extremely difficult without specially designed metering devices. Dosing is especially difficult in cases where the functional ingredient is, for example, very hygroscopic or has low flowability (increased “stickiness”).

Another known solution is a capsule [International Application WO2015001340, publ. 01/08/2015], in which the functional ingredient is distributed on the inner surface of the capsule in a water-dispersible coating. The part of the capsule, on the surface of which there is a specified coating, is separated from the part of the capsule in which the ingredient for preparing the beverage is placed, a layer of flexible film material. However, this known capsule has several disadvantages. It can also have different sizes and designs than a standard capsule, so standard equipment is not suitable for the manufacture of such capsules. In addition, the water-dispersible layer, the composition of which is described in the application, contains a number of compounds, and it is transferred to the drink, therefore, affects the organoleptic properties of the drink.

A typical capsule for preparing a coffee beverage in a coffee machine is described, for example, in [Patent RU2243934, publ. 10.01 .205]. The capsule contains the walls, base of the capsule and capsule lid. The capsule contains the ingredient for making the drink - coffee powder. Between the bottom of the capsule and a portion of coffee powder there is a filter element made in the form of an open type vessel having a lower part with openings whose diameter is smaller than the diameter of an individual particle for making a coffee beverage. Between the bottom of the filter element and the base of the capsule there is a cavity for the entry of the punch.

The technical result achieved by the invention is to provide a simple and accurate dosing of the functional ingredient in the capsule for the preparation of the beverage, without changing the assembly process on the production line of the capsule, ready for use. In the filter element for capsules intended for the preparation of drinks containing at least one functional ingredient, made in the form of an open vessel having a water-permeable lower part, which is impermeable to insoluble particles of the beverage preparation ingredient, and the wall according to the invention in the inner the space of the open vessel is placed a predetermined amount of at least one water-soluble functional ingredient deposited on the surface nnogo in a form not obstructive beverage insoluble carrier with open pores, and the filter element has a top cover which is permeable, resistant to rupture at a pressure of water required to prepare the beverage, and impervious to particles insoluble ingredient for preparing a beverage. An essential feature is that the shape and dimensions of the open type vessel having a water-permeable lower part in the present invention remain the same as in the filter element for capsules intended for the preparation of drinks that do not contain the introduced functional ingredient. The proposed solution makes it possible not to violate the traditional technology for the production of portioned capsules, the only difference is that instead of the previously known filter element, the filter element according to the proposed invention is used during assembly. To accurately dispense a predetermined amount of a functional ingredient, it is proposed to use an insoluble, open-pore carrier on the surface of which a functional ingredient is applied. Application of the functional ingredient can be carried out, for example, by wetting the surface of the open-pore carrier with a solution containing the functional ingredient in a certain concentration, and then drying it, or by other methods (manual or automatic application or spraying of the solution) to ensure uniform distribution of the functional ingredient. Then, the distribution density of the functional ingredient on the surface of the carrier is determined, and the dosage of the functional ingredient is carried out by placement in the inner the space of the vessel of the open type of the required amount (in size or weight) of the carrier.

The administered functional ingredient is preferably selected from the group consisting of water-soluble vitamins, biologically active substances, macroelements, microelements and plant extracts containing said substances. The functional ingredients used must be soluble in water, resistant to high temperatures (more than 50 ° C), that is, do not lose their properties during the preparation of the drink.

The insoluble carrier of the functional ingredient can be made in the form of at least one sheet, and this sheet must at least partially cover the lower part of the filter element in order to ensure the effective passage of the beverage through the carrier over its entire area, and thus effectively wash off the functional surface ingredient with carrier. The implementation of the carrier in the form of a sheet is very convenient for accurate dosing of the functional ingredient, since it is easy to measure and precisely cut the required area of the carrier.

The insoluble carrier of the functional ingredient, made in the form of a sheet, can be made of a material selected from the group comprising polymeric materials, glass and ceramic materials.

The insoluble carrier of the functional ingredient can be made in the form of two or more sheets, on the surface of each of which various functional ingredients are applied. This allows you to combine various action additives, such as vitamins and dietary supplements.

Two or more functional ingredients may be applied to the surface of an insoluble carrier sheet.

The insoluble carrier of the functional ingredient can be made in the form of volumetric bodies, which makes it easy to dose the functional ingredient with a known distribution on the carrier, by varying the number of volumetric bodies placed in the filter element. The insoluble carrier of the functional ingredient can be made in the form of volumetric bodies of a form selected from the group including a spherical, cylindrical, cubic shape, and volumetric bodies have predominantly the same shape and size.

The bulk bodies of the insoluble carrier are preferably made of a material selected from the group consisting of polymeric materials, glass and ceramic materials.

The upper cover of the filter element is mainly made of a material selected from the group including polymer films, filter paper, metal foil.

The invention is illustrated by the examples depicted in the figures.

The capsule has walls 6, the base of the capsule 7 and the lid of the capsule 8. The filter element rests on the walls of the capsule 6 over the entire surface area of its side walls 2. Ingredient for making a drink - coffee powder 9 is placed in the capsule between the capsule cover 8 and the top cover of the filter element 5 . Between the lower part of the filter element 1 and the base of the capsule 7 there is a cavity 10 for the entry of the punch 1 1.

Brewing water for brewing the coffee powder 9 contained in the capsule and enriching with the functional ingredients contained in the filter element 4 is supplied under a pressure of 12 atm from the outside through a punched hole 12 in the capsule lid 8. Next, the brewing water enters the capsule where it is washed with coffee powder 9. Through the top cover of the filter element 5, which is impermeable to particles of coffee powder, the brewed coffee drink enters the cavity of the filter element, where the functional ingredient - vi the amine B2 deposited on the insoluble carrier 4 with open pores, while preventing the beverage from contacting the dissolved functional ingredient with coffee powder particles, therefore, the adsorption of the functional ingredient on coffee powder particles is prevented. Then the brewed coffee containing the functional ingredient - vitamin B2 flows through the holes in the lower filter 1 of the filter element to the central hole made by the punch 11 at the base of the capsule 7, from where it flows out of the capsule.
