Apparatus for preparing a beverage through extraction of a base material

摘要

An apparatus for preparing an extract beverage through extraction of a base material provided in an extraction space (4), to which a liquid is added for obtaining the extract beverage. The apparatus comprises a drum-shaped filter element (2) which surrounds at least a part of the extraction space. The apparatus further comprises driving means (10) for rotating the filter element (2) around an axial axis of the filter element and thereby whirling the extract beverage from the extraction space, while the extracted base material is left behind in the extraction space. The driving means (10) invert the direction of rotation of the filter element at least once during the extraction process. <IMAGE>
