Description
<B>Zusatzpatent</B> zum Hauptpatent Nr. 135700. Vorrichtung zur Herstellung von Kaffeeaufgüssen, die frei von coffein und Röstgiften sind. Im Hauptpatent Nr. 135700 ist eine Vor richtung zum Befreien von Kaffeeaufgüssen von Koffein und Röstgiften geschützt, welche durch einen ein aktives Adsorptionsmittel ent haltenden Durchlaufraum für den Haffeeauf- guss gekennzeichnet ist.
Die Vorrichtung gemäss dem vorliegenden Zusatzpatent, welche eine spezielle Ausfüh rungsform der im Hauptpatent geschützten Vorrichtung darstellt, ist dadurch gekenn zeichnet, dass das aktive Adsorptionsmittel in mehreren im Durchlaufraum für den Kaffee aufguss eingebetteten Filterkörpern, zum Bei spiel Filterpapieren, derart verteilt enthalten ist, dass bei Durchlauf durch nur einen Fil terkörper erst Bitterstoffe und Röstgifte, aber wenig Koffein entzogen wird, und erst durch Verwendung einer bestimmten Anzahl weite rer Filterkörper im Durchlaufraum der be nötigte Effekt erreicht wird.
Dadurch wird es möglich, die Filterkörper je nach ihrer Be anspruchung und Funktion einzeln zu ge brauchen und auszuwechseln. Dabei können auch mehrere Filterkörper verwendet werden, die das Adsorptionsmittel in einer solchen Menge enthalten, dass die Filterkörper zusammen für die Bereitung eines einzigen Kaffeeaufgusses genügen, durch den einmaligen Gebrauch verbraucht werden und weggeworfen werden können. Dadurch wird es möglich, für jeden gaffeeaufguss wieder besondere neue Filterkörper zti verwenden.
<B> Additional patent </B> to main patent No. 135700. Device for the production of coffee infusions that are free from caffeine and roasting toxins. In the main patent no. 135700 a device for freeing coffee infusions from caffeine and roasting poisons is protected, which is characterized by a flow space containing an active adsorbent for the yeast infusion.
The device according to the present additional patent, which represents a special Ausfüh approximate form of the device protected in the main patent, is characterized in that the active adsorbent is contained in several filter bodies embedded in the flow space for the coffee infusion, for example filter papers, in such a way that when passing through only one filter body only bitter substances and roasting toxins, but little caffeine is removed, and the required effect is only achieved by using a certain number of further filter bodies in the flow space.
This makes it possible to use and replace the filter bodies individually depending on their loading and function. It is also possible to use several filter bodies which contain the adsorbent in such an amount that the filter bodies together are sufficient for the preparation of a single coffee infusion, are consumed by the single use and can be thrown away. This makes it possible to use special new filter bodies for each gaffe infusion.
