Embodiment Construction

[0036] In the figures, the device according to the invention is generally indicated by 1 . This forms part of a larger coffee machine. Only the parts relevant to the invention are shown in the drawings. The stationary housing 2 has a discharge device 3 for brewed coffee. The discharge device 3 is part of an annular channel 4 .

[0037] The inlet for the coffee / water mixture is indicated at 5 . Water is introduced via pipe 6 . The water is hot water. The coffee is introduced via an inlet 8 which is configured, for example, as a screw conveyor 8 . The mixture moves downwards via the fixed inlet 5 and into the annular channel 9 under the force of gravity. There is a mounted holder so that it can be rotated. This consists of a cylinder 10 with a top wall 11 . A piston 16 comprising a top surface or wall 17 and a bottom wall or surface 19 is mounted in the cylinder 10 .

[0038] In FIG. 2 the top wall 11 of the cylinder is shown in cross section. It can be seen from this ...

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.

Description

technical field [0001] The invention relates to a device for preparing a coffee beverage comprising a holder rotatable about a substantially vertical axis, said holder being driven by an electric motor, the holder comprising a rotating base and a peripheral wall extending around the base, wherein said peripheral wall acts as a filter for retaining coffee and allowing the prepared beverage to pass through, wherein said portion of said peripheral wall acting as a filter extends substantially parallel to said axis of rotation, the holder also comprising a top, and wherein said top or bottom is linearly movable in the direction of said axis of rotation along said peripheral wall portion acting as a filter, and has a function for removing powder from said filter Removal means provided with a fixed collection chamber for the used powder and a discharge means engaging said filter for the prepared beverage. [0002] More specifically, the present invention relates to a device in whic...
