Verfahren und Adsorptionsmasse zum Befreien der Katfeeanfgiisse von Koffein nnd Röstgiften.
Im Stammpatent Nr. 121782 ist ein Verfahren zum Befreien der Kaffeeaufgüsse von Koffein und Röstgiften unter Schutz gestellt. welches im wesentlichen darin besteht. dass der
EMI1.1
Zeit, so ergibt sich, dass dessen Wirkung allmählich nachlasst und schliesslielh ganz aufhört. Für den Laien, in dessen Hand das Verfahren zur Ausübung gegeben werden soll, besteht keine Möglichkeit, festzustellen, welchen Grad von Adsorptionsfähigkeit ein bereits einige Zeit benutztes Filter besitzt.
Benutzt man daher. wie die im Stammpatent geschützte Vorrichtung zeigt. eine Menge von Adsorptionsmaterial, die für eine grössere Zahl von Entziehungen ansreiht. so besteht die Gefahr, dass der Benutzer die Filtermasse nicht rechtzeitig ernenert und daher die Wirkung des Verfahrens unter Umständen gar nicht eintritt.
Um diesen Nachteil zu beseitigen wird das Verfahren in folgender Weise abgeändert.
Es wird eine in ihrer Adsorptionsfähigkeit für eine bestinnnte Aufgussmenge dosierte Filtermenge nur einmalig benutzt und dann beseitigt. Dieses neue Verfahren bietet aber in seiner praktischen Durchführung grosse Schwierigkeiten. Bei der Herstellung von Kaffee im Haushalt sind die einzelnen Aufgussmengen verhältnismässig klein und die zur einmaligen Behandlung dieser kleinen Menge erforderliche Menge vom Adsorptiommittel ist ganz ausserordentlich gering. Fasst man daher das Adsorptionsmittel in Form einer FiIterpatrune zusammen, so kommt man zu einer Durchlaufoffnung von so kleinem Querschnitt, dass die Filterzeit unzulässig verlängert wird.
Um einen genügend grossen Filterquerschnitt zu schaffen, wird daber nach der Erfindung die Adsorptionsmasse in fein gepulvertem Zustande in einen Tragkörper. z. B. ein Filterpapier derart eingebettet, dass die einzelnen Körnehen in annähernd einer Ehene nebeneinanderliegend eine grössere Fläche bedecken. Zweckmässig wird das Einbetten des Adsorptionsmittels bereits bei der Herstellung des Filterpapiers bewirkt, indem man es in die noch flüssige Papiermasse einrührt.
PATENT-ANSPRÜCHE :
1. Verfahren zum Befreien der Kau'eeaufgüsse von Koffein und Röstgiften nach Stammpatent Nr. 121782 dadurch gekennzeichet, dass abgegrenzle Mengen von Kaffeeaugfuss jeweils durch in ihrer Adsorptionsfähigkeit für diese Mengen dosierte Adsorptionsmassen hindurchgeleitet und die Adsorptionsmassen nach dieser einmaligen Benutzung heseitigt werden.

Process and adsorption material for freeing the catfees from caffeine and roasting toxins.
In the parent patent No. 121782, a process for removing caffeine and roasting toxins from coffee infusions is protected. which essentially consists of it. that the
EMI1.1
Time, it follows that its effect gradually wears off and finally ceases completely. For the layperson, in whose hand the procedure for the exercise is to be given, there is no possibility of ascertaining what degree of adsorption capacity a filter which has already been used for some time has.
One uses therefore. as the device protected in the parent patent shows. a lot of adsorbent lining up for a greater number of withdrawals. so there is the risk that the user does not renew the filter material in time and therefore the effect of the method may not even occur.
In order to overcome this disadvantage, the method is modified as follows.
A filter amount dosed in its adsorptive capacity for a certain amount of infusion is used only once and then eliminated. However, this new method offers great difficulties in its practical implementation. When making coffee in the home, the individual amounts of infusion are relatively small and the amount of adsorptive agent required for one-time treatment of this small amount is extremely small. If the adsorbent is therefore combined in the form of a filter cartridge, the result is a passage opening with such a small cross section that the filter time is inadmissibly extended.
In order to create a sufficiently large filter cross-section, according to the invention, the adsorption mass is in a finely powdered state in a support body. z. B. a filter paper embedded in such a way that the individual grains in approximately a marriage next to each other cover a larger area. The embedding of the adsorbent is expediently effected during the production of the filter paper by stirring it into the still liquid paper pulp.
PATENT CLAIMS:
1. A method for freeing the chewing infusions from caffeine and roasted poisons according to the master patent no. 121782 characterized in that delimited amounts of coffee foot are passed through adsorption materials that are dosed in their adsorption capacity for these amounts and the adsorption materials are removed after this single use.
