Cleaning gas flows through the granules falling through the device, opposite to the direction of movement of said granules. In the inlet region there is provided a guide device (19) for the inflowing grains (1) and a retaining device (2) for the larger particles (3). The distributing plate (6) is provided with a cover cowl (16) which has an opening (17) for the inlflowing grains. Between the distributing plate (6) and cover cowl (16), a gap (8) is provided which preferably has a height of approx. 8 to 15 mm. <IMAGE>
