Abstract: The pellet dosing apparatus comprises a hopper (10) pouring pellets (1) on a chute (30) which is vibrated by a vibrator device (3) to move the pellets (1) forward along the chute until dropping them from a discharging end (30a). A counting device (20) is arranged for counting the number of pellets (1) falling from said discharging end (30a) of the chute (30) into a dosing container (4). The pellets (1) are retained in the dosing container (4) by transferring means until their number reaches an amount corresponding to a pre-established dose determined by control means based on a counting signal received from said counting device (20). The control means then control the transferring means to transfer the pellets from the dosing container to an output duct.
