Filling system for a container for solid particles

A device for dispensing solid particles for a storage container filling system comprising at least one scattering element for homogeneously filling the container with solid particles, each scattering element comprising at least one rotating plate provided with fins making it possible to eject, by centrifugal force, the solid particles in a homogeneous distribution, wherein the fins comprise, at their periphery, brushes comprising series of flexible bristles extending along a projection surface in the form of an inverted T so that the brushes deform elastically as the solid particles pass in order to protect the solid particles between them and then restore this absorbed energy in order to direct the final ejection toward the container of solid particles, wherein each brush comprises a first vertical upper series of bristles which joins a second lower series of horizontal bristles at the median level of the second lower series of horizontal bristles, the second lower series of bristles extending, from the end of each fin, in an upward oblique direction, from the end of each fin, with respect to the horizontal axis, so that at least the free ends of the second series of bristles are located in the path of the solid particles emerging between two fins.
