A device (100) for dispensing a loose solid material (P), comprising a plurality of vibrating elements (210) arranged flanked to one another such as to restingly support the material (P), each of which is associated to a piezoelectric means (220) suitable for converting an electrical excitation signal into a mechanical vibration which can cause a fall of material (P) from the vibrating elements (210), and heating means (240, 245) for heating the vibrating elements (210). |
