The invention relates to a flow guiding device in a wort copper used for deviating a heated wort flow which is moving upward in a wort copper and positioned above the wort flow outlet. After deviation of the wort essentially radially towards the outside the wort flow flows against said device. On the approach-flow side of the flow guide device partial ridges are positioned which extend essentially in a radial direction. The guiding device is characterized in that: said partial ridges (11) are arranged in such a way that between two adjoining partial ridges (11) a flow segment (12, 13, 14, 15, 16, 17, 18, 19, 20, 21) is configured which expands radially towards the outside and is radially open to the outside; said segment is closed in an axial direction in relation to the direction of wort flow (7) by an approach-flow surface element (31, 35) which connects the two adjoining partial ridges (11); the approach-flow surface elements (31, 35) of each pair of adjoining flow segments (12, 13, 14, 15, 16, 17, 18, 19, 20, 21) have a different angle of incidence ( alpha , beta ) moving from radially inside to radially outside in relation to a plane (32a, 32b) which is perpendicular to the direction of flow (7), in such a way that the wort flow is broken up. |
