Description
FILTER PAPER INSERT FOR PRODUCING FILTERED COFFEE AND METHOD FOR
PRODUCTION OF SUCH A FILTER PAPER INSERT
The present invention relates to a filter paper insert for producing filtered coffee, the filter paper insert being furnished with a flavor carrier for changing the taste of the coffee.
The invention further relates to a method for production of such a filter paper insert. Filter paper inserts of the general class are known in themselves.
The adding of flavor carriers for changing the taste of the coffee has until now occurred mainly by providing an appropriate filter paper insert with an additional holding chamber and filling into this chamber a powder-form flavoring, the flavoring substance of which is dissolved in the filtering process.
Also known is the method of producing filter paper inserts from a filter paper that is soaked on all surfaces with a liquid flavoring carrier. Filter paper inserts produced in this manner require a special packaging and are difficult to handle.
In addition, DE 40 28 492 A1 shows flavor filter-inserts for coffee filters, which inserts are arranged inside the coffee filter.
Described in DE 18 32 952 U is a filter paper that is impregnated with vitamins, trace elements, or similar supplements.
The objective upon which the present invention is based is to show a filter paper insert of the general class that makes possible a changing of the taste of the coffee, but does not require for this purpose the creation of special holding chambers and the filling of the latter with flavor carriers.
According to the invention, this objective is accomplished through the fact that the flavor carrier is integrated into a coating that is applied to the filter paper insert and consists of a flavoring material constituting the flavor carrier, a carrier material, and a solvent.
This measure according to the invention makes it possible in a simple manner to prepare a filter paper insert such that a desired changing of the taste of the coffee is possible without requiring a change to the filter paper insert itself in terms of construction.
PRODUCTION OF SUCH A FILTER PAPER INSERT
The present invention relates to a filter paper insert for producing filtered coffee, the filter paper insert being furnished with a flavor carrier for changing the taste of the coffee.
The invention further relates to a method for production of such a filter paper insert. Filter paper inserts of the general class are known in themselves.
The adding of flavor carriers for changing the taste of the coffee has until now occurred mainly by providing an appropriate filter paper insert with an additional holding chamber and filling into this chamber a powder-form flavoring, the flavoring substance of which is dissolved in the filtering process.
Also known is the method of producing filter paper inserts from a filter paper that is soaked on all surfaces with a liquid flavoring carrier. Filter paper inserts produced in this manner require a special packaging and are difficult to handle.
In addition, DE 40 28 492 A1 shows flavor filter-inserts for coffee filters, which inserts are arranged inside the coffee filter.
Described in DE 18 32 952 U is a filter paper that is impregnated with vitamins, trace elements, or similar supplements.
The objective upon which the present invention is based is to show a filter paper insert of the general class that makes possible a changing of the taste of the coffee, but does not require for this purpose the creation of special holding chambers and the filling of the latter with flavor carriers.
According to the invention, this objective is accomplished through the fact that the flavor carrier is integrated into a coating that is applied to the filter paper insert and consists of a flavoring material constituting the flavor carrier, a carrier material, and a solvent.
This measure according to the invention makes it possible in a simple manner to prepare a filter paper insert such that a desired changing of the taste of the coffee is possible without requiring a change to the filter paper insert itself in terms of construction.
Also, the use of the filter paper insert according to the invention is no different from the use of filter paper inserts by which a changing of the taste of the filtered coffee is not possible.
The coating applied to the filter paper insert, which coating obviously consists only of foodstuff-safe components, can be applied to a filter paper in a liquid state and then quickly dried, so that, without loss of the active material of the flavor carrier itself, the filter paper insert can be used and handled just as an untreated filter paper insert.
According to a further concept of the invention the carrier material consists of starch, preferably modified starch.
This brings with it the advantage that the filtration characteristics of the filter paper insert remain virtually unchanged, since the aforementioned carrier material of starch, preferably modified starch, is again dissolved in the filtering process by the brewing water, so that the flow-through speed of the brewing water and thus the filtration characteristics of the filter paper inserts remain virtually unchanged in comparison to an untreated filter paper insert.
The coating can be applied to the filter paper of the filter paper insert over the entire surface of the latter; it is likewise possible to carry out a coating only regionally.
The coating can be sprayed onto the filter paper in its liquid state, or pressed onto it, or applied to the filter paper in other appropriate ways, so that the production of a filter paper insert according to the invention with the desired added uses is, in the end, possible at the same rate as the production of an untreated filter paper insert.
In particular in the case of a bag-like filter paper insert with two superimposed filter paper layers, which are joined to each other by embossed seams, it is advantageous to apply the coating to a finished filter paper insert.
The advantages of this lie particularly in the fact that the strength of the embossed seams corresponds to that of untreated filter paper inserts and, in addition, only so much coating material is ever used as is necessary for the coating of a finished filter paper insert.
A method for production of a filter paper insert according to the invention is characterized through the fact that an emulsion is first produced from starch, preferably modified starch, a solvent, and flavoring materials, and that this emulsion is subsequently applied to filter paper used for producing a filter paper insert or to a finished filter paper insert.
In this, the use of an emulsion comprising the following components is preferred:
- organic, artificial, or natural flavoring materials or a mixture of flavoring materials of these categories - 1,2-propandiol - demineralized water - modified starch with emulsifying and encapsulating characteristics, e.g.
Preferably, the emulsion is sprayed or pressed onto the finished filter paper insert.
Additional features of the invention are the object of further dependent claims.
Embodiment examples of the invention are represented in the accompanying drawings and are described in detail in the following.
The drawings show:
Fig. 1: a view of a frustum-like filter paper insert according to the present invention, the shape of which is known Fig. 2: a plan view of a filter paper insert according to the present invention after the manner of a round filter sheet Fig. 3: a schematically represented cross-sectional region of a filter paper for a filter paper insert according to Figs. 1 or 2 Fig.4: a frustum-like filter paper insert according to a further embodiment example of the invention, with partially cut-away side wall Represented in Figs. 1, 2 and 4, in an exemplary manner, filter paper inserts 1 in a geometrical shape known in itself.

Preferably, the emulsion is sprayed or pressed onto the finished filter paper insert.
Additional features of the invention are the object of further dependent claims.
Embodiment examples of the invention are represented in the accompanying drawings and are described in detail in the following.
The drawings show:
Fig. 1: a view of a frustum-like filter paper insert according to the present invention, the shape of which is known Fig. 2: a plan view of a filter paper insert according to the present invention after the manner of a round filter sheet Fig. 3: a schematically represented cross-sectional region of a filter paper for a filter paper insert according to Figs. 1 or 2 Fig.4: a frustum-like filter paper insert according to a further embodiment example of the invention, with partially cut-away side wall Represented in Figs. 1, 2 and 4, in an exemplary manner, filter paper inserts 1 in a geometrical shape known in itself.
The filter paper inserts 1 according to Figs. 1 and 4 are designed in each case in a double-layered manner and display an essentially frustum-like outline.
Such bag-like filter paper inserts are the most commonly known and used filter paper inserts;
however, filter paper inserts 1 according to Fig. 2 in the form of a round filter sheet are also frequently used.
Irrespective of the geometric shape of the filter paper insert 1, its special characteristic according to the present invention is to be seen in the fact that the filter paper 2 used for its production is provided with a coating 3 (see Fig. 3), which consists in essence of a flavoring material constituting a flavor carrier, a carrier material, and a solvent.
This coating 3 can be applied to the filter paper 2 over its entire surface or, as Fig. 4 clearly shows, applied only regionally to the filter paper 3. The coating 3 dries after its application to the filter paper 2 in a relatively short time, so that the finished filter paper insert 1 can be handled and used just as an untreated filter paper insert. Nevertheless, the flavoring materials are integrated into the coating 3 and these flavoring materials are dissolved during the production of filtered coffee by the heated brewing water passing through and contribute then to a changing of the flavor of the coffee.
Advantageously, used as the carrier material for the coating 3 is a starch, preferably a modified starch.
Used as the solvent is water, preferably demineralized water, alcohol, or a mixture of water and alcohol.
As the flavoring material, application can be made of natural, artificial, or organic flavoring materials, or a mixture of flavoring materials of these categories.
The coating 3 can be applied over the entire surface or regionally to the filter paper insert 1.
It is equally possible to apply the coating 3 to the top side, considered in the flow-through direction of the brewing water, of the filter paper insert 1 as to its underside, considered in the same manner.
The application of the coating 3 is possible both by a pressing process and by a spraying-on process, the latter method being especially sensible when the coating is to be applied to a finished filter paper insert 1.
In this, the coating can be applied either over the entire surface or only regionally, in which case the possibility exists of providing for a flavoring-material gradation. In the case of a flavoring-material gradation, the flavoring concentration should increase towards the bottom of the filter paper insert 1.
As the flavoring carrier, the coating 3 can contain both a liquid flavoring and a powder-form flavoring.
According to the method, the production of a filter paper insert according to the present invention takes place as follows: First of all, an emulsion is produced from starch, preferably modified starch, a solvent, and flavoring materials, and this emulsion is subsequently applied to the filter paper used to produce a filter paper insert 1 or applied to a finished filter paper insert 1.
In this, an emulsion is preferred which contains in essence the following components:
- organic, artificial, or natural flavoring materials or a mixture of flavoring materials of these categories 1,2-propandiol demineralized water - modified starch with emulsifying and encapsulating characteristics, e.g.
It is especially economical to spray or press the emulsion onto a finished fitter paper insert 1.
The filter paper insert 1 can be optimally finished in a conventional manner before the spraying or pressing on of the emulsion, and in the subsequent application of the coating to the finished filter paper insert 1 only so much emulsion is consumed as is necessary for the whole-surface or partial coating of the filter paper insert 1.
If the filter paper insert is provided with a coating only regionally, then it is advantageous to moisten with water, during the application of the coating the regions that are not coated, in order to avoid the formation of waves or folds in the filter paper In connection with the handling of a filter paper insert, it is perhaps sensible to leave the upper edge region, which during handling of the filter paper insert 1 is usually grasped, free of coating.
Such bag-like filter paper inserts are the most commonly known and used filter paper inserts;
however, filter paper inserts 1 according to Fig. 2 in the form of a round filter sheet are also frequently used.
Irrespective of the geometric shape of the filter paper insert 1, its special characteristic according to the present invention is to be seen in the fact that the filter paper 2 used for its production is provided with a coating 3 (see Fig. 3), which consists in essence of a flavoring material constituting a flavor carrier, a carrier material, and a solvent.
