Description

Verfahren zur Herstellung von Puderkaffee Es ist bekannt, durch Fe instvermahlung den Grad der Auswertbarkeit von Kaffeebohnen zu Kaffeegetränk zu verbessern.Process for the production of powdered coffee It is known by Fe instgrinding increases the degree of evaluability of coffee beans for coffee beverages to enhance.

Bei der Feinstmahlung von Kaffee stört das in den Kaffeebohnen vorhandene Pflanzenfett. Je höher der Feinheitsgrad bei der Zerkleinerung getrieben wird, um so mehr neigt das entstehende Pulver zum Verkleben, wodurch sich Störungen in der Mahlvorrichtung ergeben.When coffee is finely ground, what is present in the coffee beans is a nuisance Vegetable fat. The higher the degree of fineness in the comminution is driven to the more the resulting powder tends to stick together, which causes disturbances in the Result in grinding device.

Es wurde nun gefunden, daß die obengenannten Störungen ausgeschaltet werden können, wenn der Rohkaffee zunächst in vorgemahlenem Zustand teilweise entfettet wird, d. h. auf etwa die Hälfte seines ursprünglichen Fettgehaltes. Dies kann geschehen durch Pressung oder durch Extraktion mit Lösungsmitteln, die imstande sind, das Fett aus dem Kaffee zu lösen, ohne dessen Gehalt an Coffein zu vermindern, wie z. B. Äther, Petroläther, Äthylacetat, Toluol, Xylol u. a. Der teilweise entfettete Rohkaffee wird geröstet und ist dann in einem Zustand, in dem er sich durch Vermahlen in Kolloidmühlen auf Feinheitsgrade bringen läßt, die bei normalem Fettgehalt nicht erreicht werden können.It has now been found that the above-mentioned disturbances are eliminated can be if the green coffee is first partially degreased in a pre-ground state will, d. H. to about half of its original fat content. This can be done by pressing or by extraction with solvents that are capable of the Dissolve fat from coffee without reducing its caffeine content, such as B. ether, petroleum ether, ethyl acetate, toluene, xylene and others. The partially defatted Green coffee is roasted and is then in a state in which it is ground by grinding can be brought to a degree of fineness in colloid mills that is not possible with normal fat content can be achieved.
