Abstract
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.
