Abstract
A coffee machine for the preparation of pressure-extracted coffee with a low particle content is provided. The coffee machine differs from known machines for pressure-extraction of coffee by comprising a filter element for reducing the particle content of coffee, which filter element is disposed downstream of the percolating sieve and is connected fluidically to the percolating sieve and to the outflow. By means of the filter element, coffee extracted by pressure in the percolating unit can be filtered before dispensing the outflow so that suspended particles and emulsified oils of a specific size are separated from the coffee by the filter element and a new coffee is produced. In addition, the coffee machine can prepare standard pressure-extracted coffee since the coffee from the percolating unit can also be guided past the filter element, i.e. need not flow necessarily via the filter element to the outflow.
