BEKANNTMACHUNG DER ANMELDUNG UNDAUSGABEDER AUSLEGESCHRIFT: 12. A P RI L 1962NOTICE THE REGISTRATION ANDOUTPUTE EDITORIAL: 12. A P RI L 1962

Die Erfindung bezieht sich auf eine Abwandlung des in der Hauptpatentanmeldung G 28646IV a/53 d geschützten Verfahrens zur Herstellung eines konzentrierten Kaffee-Extraktes aus einem Gemisch aus gemahlenen Röstkaffeeteilchen und gekörnten Kaffeefeinstteilchen in Extraktionsanlagen, bei dem zwecks Verhinderung durchflußhemmender, zusammenhängender Feinstteilchenschichten während des Extraktionsvorganges als Extraktionsgut ein Gemisch verwendet wird, das neben den groben, gemahlenen Röstkaffeeteilchen druckverformte Feinstteilchenpreßlinge von größerer Korngröße als die groben, gemahlenen Röstkaffeeteilchen enthält.The invention relates to a modification of the main patent application G 28646IV a / 53 d Protected process for the production of a concentrated coffee extract from a mixture from ground roast coffee particles and granular coffee fines in extraction systems, in which for the purpose of preventing flow-inhibiting, coherent layers of fine particles during of the extraction process, a mixture is used as extraction material, which in addition to the coarse, ground Roasted coffee particles compression-molded fine particle compacts of larger grain size than that contains coarse, ground roasted coffee particles.

Die Hauptpatentanmeldung befaßt sich dabei in der Hauptsache mit der Verwendung derjenigen Feinstteilchen, die bei der Extraktion des Kaffeeöls aus dem Röstkaffee anfallen und als Preßkuchenmehl bezeichnet werden. Dabei wird auch schon angeregt, neben oder zusammen mit diesem Preßkuchenmehl die beim Mahlen des Röstkaffees an- ao fallende Feinkornfraktion, den sogenannten Mahlstaub, als Bestandteil der druckverformten Feinstteilchenpreßlinge zu verwenden.The main patent application deals mainly with the use of those Very fine particles that arise during the extraction of the coffee oil from the roasted coffee and as press cake flour are designated. It is also stimulated next to or together with this press cake flour the fine grain fraction that occurs when the roasted coffee is ground, the so-called grinding dust, to be used as a component of the compression molded fine particle compacts.

Die Zusatzerfindung besteht darin, als Extraktionsgut ein Gemisch zu verwenden, dessen druckver- formte Feinstteilchenpreßlinge ausschließlich aus der Feinteilchenfraktion des gemahlenen Röstkaffees besteht. Ein solches Extraktionsgut enthält also überhaupt keine Preßkuchenmehl-Anteile. Es hat sich gezeigt, daß solches Preßkuchenmehl für die Durchführung des grundsätzlichen Erfindungsgedankens nicht zwingend ist.The additional invention consists in using a mixture as extraction material, the pressure of which Formed fine particle compacts consist exclusively of the fine particle fraction of the ground roast coffee. Such an extraction material does not contain any components of press cake flour. It has shown that such press cake flour for carrying out the basic concept of the invention is not mandatory.

Die Herstellung des Extraktionsgutes und seine Verarbeitung in Perkolationssäulen zum konzentrierten Kaffee-Extrakt erfolgt nach den in der Haupt-Patentanmeldung beschriebenen Verfahren und Gesichtspunkten. The production of the extraction material and its processing in percolation columns for concentrated Coffee extract takes place according to the methods and aspects described in the main patent application.
