Abstract
A dosing apparatus for dosing a product in powder and/or granule form within containers includes a hopper () provided with an internal cavity () to contain the product, a dosing screw () rotatable about, and extending along, a rotation axis (X) inside the hopper and through the internal cavity, and a first driving shaft () arranged to rotate the dosing screw; the dosing apparatus also includes a magnetic coupling system () to removably connect a first end () of the dosing screw () to the first driving shaft (), arranged externally to the hopper (); the magnetic coupling system includes groups of magnets () adapted to magnetically transmit a driving torque from the first driving shaft () to the dosing screw () and to reversibly fasten, longitudinally along the rotation axis (X), the dosing screw () to the first driving shaft (); the first end () of the dosing screw () is arranged inside the hopper () and the first driving shaft () is hermetically separated from the first end () of the dosing screw () by means of a separation element () that is integral with the hopper ().
