Abstract
Device (1) for the preparation of coffee, wherein a water/coffee powder mixture is introduced into a cylindrical space (10). The cylindrical peripheral wall (15) is made as a vertical screen and by rotation/centrifugation the prepared beverage is forced through the filter to the outside, whilst granular coffee material remains behind. The top part (17) and the bottom part (19) of the holder (16) are made such they can be moved with respect to the cylinder wall. The motor (26) for rotation is above or below the top part or, alternatively, bottom part. Furthermore, there is a construction for producing the displacement of the top part or bottom part of the holder with the same motor.
