CA 2084699

A beverage extraction machine in which powdered material such as coffee is mixed with hot water in an extraction chamber which is mounted over a beverage receiver with a filter mounted between them. High pressure air is supplied into the beverage receiver and passes up through the filter to agitate the hot water and powdered material in the extraction chamber. Then air is sucked from the beverage receiver and drums the brewed coffee from the extraction chamber through the filter into the beverage receiver where it is discharged to a cup. A pressure sensor can be used to control the application of the high and low pressure air.

Machine utilisée pour l'extraction de boisson dans laquelle une matière en poudre, notamment du café, est mélangée à de l'eau chaude à l'intérieur d'une chambre d'extraction installée sur le dessus d'un dispositif de réception de boisson, un filtre étant disposé entre la chambre et le dispositif de réception. De l'air est amené sous haute pression vers le dispositif de réception, traverse le filtre et agite l'eau chaude et la matière en poudre à l'intérieur de la chambre d'extraction. L'air est par la suite aspiré du dispositif de réception et entraîne le café infusé contenu dans la chambre d'extraction dans le filtre jusqu'au dispositif de réception d'où il est distribué dans une tasse. Un capteur de pression peut être utilisé pour régler la pression d'air à appliquer.
