Mocha-making apparatus with separating of steam fraction

Abstract

An apparatus for preparing a coffee beverage inducing the passage of an extraction fluid through a dose of coffee by heating said fluid, includes a separating device arranged to separate a fraction of said beverage obtained with a prevalently liquid phase of said fluid from a further fraction of said beverage obtained with a prevalently steam phase of said fluid; an apparatus for preparing a coffee beverage by imbibing a dose of coffee with an extraction fluid driven by heating through said dose, includes an inhibition device arranged to inhibit said imbibing when said fluid contains a substantial steam phase; a method for obtaining a coffee beverage includes heating an extraction fluid so as to induce the passage of said extraction fluid through a dose of coffee to obtain said beverage and separating a fraction of said beverage obtained with a prevalently liquid phase of said extraction fluid from a further fraction of said beverage obtained with a prevalently steam phase of said extraction fluid is provided for.
