  • Filling unit substantially comprises a carousel rotating about a rotation axis, a tank containing the pourable food product, and a plurality of control valves which are fluidically connected with the tank and are supported by the carousel in a radially external position with , respect to the rotation axis of the carousel .
  • the replenishing device comprises a hollow tube defining a pouring opening and a replenishing valve movable between a closure position and an open position.
  • Replenishing valve comprises, in turn, a shutter and a stem which may slide within the hollow body.
  • the shutter prevents the pourable product from flowing through the pouring opening in the closed position of the replenishing valve, and allows the pourable product to flow through the pouring opening in the open position of the replenishing valve.
  • tank is replenished from the top.
  • the pouring opening of the replenishing tube is arranged below the free level of the pourable product within the tank and the replenishing valve is arranged considerably above such free level.
  • the distance between the control valve and the pouring opening of the replenishing tube may range between 1 and 2 metres .
  • the fall of the pourable product for such a distance ' may generate turbulence and foam, which may penalize the correct replenishment of the tank.
  • the fall of pourable product may reduce its pressure under the environment pressure. Accordingly, in case that only a portion of it reaches the external environment due for example to a leakage, the whole pourable product may be contaminated by external agents .
  • tank is filled from the bottom at a certain pressure and by using a pump, so as to prevent the generation of foam and the reduction of the pressure of the pourable product falling within the tube .
  • a drawback of this second method is that it is necessary to provide some couplings, e.g. O-rings and/or collector, between fixed and rotating components.

  • Appendices 30 carry out two different functions: - when shutter 21 is in the closed position, they contribute to ensure that the axis of shutter 21 coincide with axis A and, therefore, with the axis of opening 14 ; and
  • shutter 21 when shutter 21 is in the open position, they abut against wall 31 due to the vibrations induced by the pourable product flow, so limiting the movement of shutter 21 within tube 10 .
  • Actuating mechanism 18 is controlled by a control unit 35 (only schematically shown in Figure 1 ) so as to move stem 16 and, therefore, shutter 21 according to a determined motion law.
