Definitions
- the present invention relates to a filling valve for filling carbonated or non-carbonated pourable products into receptacles, such as containers or bottles made of glass, plastics, aluminum, steel or composites.
- the present invention also relates to a filling apparatus having a plurality of such filling valves.
- the present invention relates to a method of operating such a filling valve.
- Filling apparatuses for filling pourable products such as carbonated liquids (e.g. sparkling water, soft drinks and beer) or non-carbonated liquids (e.g. still water, juices, teas, sport drinks, liquid cleaners, wine, emulsions, suspensions, high viscosity liquids and beverages containing pulps) into receptacles such as bottles, containers or the like typically comprise a plurality of filling valves adapted to direct the pourable product into the receptacles.
- such a filling apparatus comprises a conveying carousel rotatable around a respective rotation axis and carrying a plurality of filling valves peripherally arranged on the conveying carousel.
- the filling apparatus receives empty receptacles at a receiving station, advances the receptacles along an arc-shaped conveying path and fills the receptacles with the pourable product.
- the empty receptacles are transferred to the respective filling valves at the receiving station, are advanced together with the respective filling valves to the transfer station and during advancement from the receiving station to the transfer station the receptacles are filled by the respective filling valves with the pourable product.
- a typical filling apparatus also comprises a supply tank containing the pourable product, the supply tank being in fluidic connection with the filling valves.
- a typical filling valve comprises a valve body having an inlet for receiving the pourable product from the supply tank, a flow channel for receiving the pourable product through the inlet and an outlet mouth through which the pourable product is directed into the receptacle for filling the latter.
- the filling valve also comprises a shutter for opening or closing of the outlet mouth so as to control the filling of the receptacle.
- Foaming of the pourable product during the filling process can lead to loss of pourable product filled into the receptacles and leads to a loss in the accuracy of the amount of pourable product filled into the receptacles. Furthermore, foaming may lead to reduced filling accuracy even without loss of the pourable product.
- the possible foaming requires that the filling speed is limited.
- a first approach consists in engaging the receptacles to the respective outlet mouths of the respective filling valves so as to obtain a sealing of the receptacle from the outside. Prior to the filling the receptacles are pressurized by the introduction of a pressurizing gas and the receptacles are depressurized during the filling of the receptacles with the pourable product.
- a second approach which is typically combined with the first approach, consists in placing a swirl-inducing member within the fluid channel, the swirl-inducing member being adapted to induce a rotational movement on the pourable product so that the pourable product enters the receptacle by flowing along the internal walls of the receptacle.
- such a swirl-inducing member comprises guiding surfaces, which are inclined with respect to the longitudinal axis of the valve body so as to change the flow direction and thereby introducing the rotation of the pourable product.
- a first drawback lies in the fact that the efficiency of the swirl-inducing members used depends on the type of the pourable product, its viscosity, the details of the inner shape of the receptacle and the filling level of the pourable product within the receptacle. As the swirl-inducing members cannot adapt their performance during the filling process, during the filling the efficiency will not be optimal during all of the filling process. As well, if the type of receptacle (and therewith the inner shape) is changed or another type of pourable product is to be filled a change of the swirl-inducing member must be performed or a loss in the efficiency must be accepted. Changing the swirl-inducing member is, however, laborious and therefore increases the overall production costs.
- a second drawback is that the swirl-inducing member needs to be removed if another kind of pourable product is to be filled for which the presence of a swirl-inducing member is inappropriate. This can e.g. be the case when the pourable product contains solid pieces.
- a third drawback is that the swirl-inducing member needs to be removed if the filling valve is to be used in a manner to centrally fill the pourable product into the receptacles.
- a typical filling apparatus comprises a plurality of filling valves peripherally arranged on a conveying carousel and, thus, the removal of the swirl-inducing member has to be done for each single filling valve.
