A device for distributing granular materials in a recipient, particularly of complex shape intended to be arranged between a feed hopper and the recipient to be filled. The device includes a deflector, mobile in rotation around an axis, lining a passage linking the hopper to the recipient. The deflector is formed by at least one surface that may be inclined in relation to the axis of rotation approaching the axis in the direction of flow of the granules, or perpendicular to the axis. According to the speed of rotation, a certain quantity of granules is ejected by the deflector and another part passes directly in the passage.
