Abstract
A filling device, enabling simultaneous filling with at least two granular materials, without mixing them, includes an inner hopper supplying a first type of material and an outer hopper supplying a second type of material, and a dispenser arranged downstream from the hoppers. The dispenser includes a central passageway arranged directly opposite the inner hopper, and a deflecting mechanism towards the exterior of the dispenser arranged directly opposite the outer hopper. The deflecting mechanism at least partially borders the central passageway. The dispenser is capable of rotating about a longitudinal axis, the direction of which is the mean direction of flow, in which the dispenser includes a central shaft including an upper end opposite the inner hopper forming a deflecting surface for the first type of material coming from the inner hopper.
