5. A high precision metering device for granular material which comprises at least one dispensing element, driving means arranged
to control said dispensing element, and a program control unit suitable for controlling said driving means and stopping upon
reaching a predetermined amount of granules dispensed by said dispensing element, and wherein said dispensing element, or
each dispensing element, is mounted for rotation about an axis of oscillation or partial rotation and has a duct substantially
shaped as an elbow extending transversely with respect to said axis of oscillation, thereby having a first substantially vertical
duct portion that, in use, is permanently filled with granular material, and a second duct portion extending in a transverse
direction with respect to said first portion and in communication therewith, thus constantly containing granular material
which, in a rest condition, is kept therewithin owing to angled structure of said dispensing element, and wherein said driving
means is designed to cause, upon control, said dispensing element to rotate or swivel about said axis of oscillation, thereby
causing granules of material to be released from said second portion of said dispensing element each time said dispensing
element is caused to oscillate or partly rotate.
