A device for application to moka espresso coffee machines, for producing coffee-cream comprises, downstream of a filter (5) overlaying a coffee powder holding basket (2), a membrane (7) made of rubber or other elastomeric material including one or more holes (8) having a very small diameter and/or one or more incisions, thereby causing a pressure increase in water passing through the coffee powder, in addition to an increase of the speed of the coffee infusion passing through the holes of the membrane.
L'invention concerne un dispositif destiné à des machines à café espresso de type <=moka>=, permettant d'obtenir de la crème de café. Ce dispositif comprend, en aval d'un filtre (5) recouvrant un panier contenant la poudre de café (2), une membrane (7) constituée de caoutchouc ou d'un autre matériau élastomère (8). Cette membrane possède au moins un trou de très petit diamètre et/ou au moins une incision, ce qui provoque l'augmentation de la pression dans l'eau passant à travers la poudre de café, et qui en outre augmente la vitesse de l'infusion de café passant à travers le ou les trous de la membrane.
