The particle supply device is provided with a cylinder (21) in which depressions (212), which are disposed at a constant pitch in the circumferential direction on the external side surface (211) of the cylinder, are configured in depression rows (213) and multiple depression rows are arranged side-by-side along the cylinder rotation axis (R1). Above the cylinder, a particle-filling opening for sequentially filling particles of an absorbent material in the multiple depressions is provided. A portion of the external side surface of the cylinder is covered by a cover from the particle-filling opening to the lower section of the cylinder, the cover spreading in the rotation direction. Near the front edge of the cover in the rotation direction, the particles are sequentially released from the multiple depressions. The areas that divide two depressions that are adjacent in the circumferential direction are called partitions (214). Because the multiple depression rows comprise at least three depression rows in which the positions of the partitions in the circumferential direction differ from each other, the impact generated by particles becoming lodged between the partitions of the multiple depression rows and the back edge of the cover in the rotation direction is dissipated and mitigated.La présente invention concerne un dispositif d'alimentation de particules doté d'un cylindre (21) dans lequel des creux (212), qui sont agencés à intervalle constant dans la direction circonférentielle sur la surface latérale externe (211) du cylindre, sont configurés selon des rangées (213) en creux et de multiples rangées en creux sont agencées côté à côté le long de l'axe (R1) de rotation du cylindre. Au-dessus du cylindre est ménagée une ouverture de remplissage de particules destinée au remplissage de manière séquentielle des particules d'un matériau absorbant dans les multiples creux. Une portion de la surface latérale externe du cylindre est couverte d'un couvercle depuis l'ouvert
