A fodder mixer (1, 20, 30, 40) is described, which comprise a mixing chamber (2) having a fodder discharge opening (6, 26) and a bottom (4, 24, 34). The mixing chamber is provided with at least two vertical screws (7, 37), which are adapted to be rotatingly driven and which are used for mixing the fodder and for moving it in a feed direction (F) to the fodder discharge opening (6, 26), each vertical screw being provided with a pick-up edge (9) which picks up fodder from the bottom and which sweeps over a flight circle projected onto said bottom. In order to optimize such a fodder mixer with respect to its conveying capacity, the present invention suggests that a fodder baffle surface (12, 13, 22, 23, 33) should be provided, which extends upwards from said bottom and which is effective in a direction opposite to the feed direction (F), said fodder baffle surface being associated with the flight circle of the pick-up edge (9) in a transition area (11, 21, 31) between neighbouring vertical screws.
