Dispensing device for a granular material

A dispensing device for a granular material, comprising a dispensing channel (20) provided with an inlet opening (21) and an outlet opening (22), wherein:

• the dispensing channel (20) comprises an inlet portion (21a) having a solid surface, an intermediate portion (23) having a solid surface, and an outlet portion (22a) having a solid surface,
• the inlet portion (21a) is configured to connect the inlet opening (21) and the intermediate portion (23) and is provided with a first longitudinal axis (X);
• the intermediate portion (23) is configured to connect the inlet portion (21a) and the outlet portion (22a) and is provided with a second longitudinal axis (Y),
• the outlet portion (22a) is configured to connect the intermediate portion (23) and the outlet opening (22) and is provided with a third longitudinal axis,
• the first longitudinal axis extends in the same direction as the third longitudinal axis (X) and in a direction different from the second longitudinal axis (Y);
• the intermediate portion (23) has a length (L) and a height (H), measured on a vertical plane containing the second longitudinal axis (Y), wherein the height (H) is measured perpendicular to the length (L);
• the intermediate portion (23) is configured to enable the deposit and accumulation of a predetermined quantity of granular material coming from the inlet opening (21);
• the intermediate portion comprises a motor that can be activated on command to cause the granular material to flow in advancement from the intermediate portion (23) towards the outlet opening (22),
• wherein the motor comprises pneumatic means (24, 25, 26), provided with a blow opening (24) located along the intermediate portion (23),
• wherein the blow opening (24) is located on a bottom wall (23a) of the intermediate portion, and
• a filter (25) extending entirely across the blow opening (24) is contiguous with the solid surface of the intermediate portion (23) and is parallel to the second longitudinal axis (Y).
