Definitions

  • the present invention relates to a flow deflector and a filling device for filling a receptacle comprising such a flow deflector.
  • the filling of flat products in aseptic or ultraclean productions occurs by keeping the filling valve spaced with respect to the inlet of the receptacle so as to avoid any contamination of the receptacle due to contact with the valve itself, and by flowing the product into the centre of the receptacle (filling "from the centre").
  • the filling of carbonated products occurs by contacting the filling valve with the receptacle.
  • the filling method of carbonated products includes a pressurisation step of the receptacle achieved by hermetically closing the inlet by means of the filling valve.
  • a constraint in filling carbonated products is reducing or avoiding the formation of foam.
  • some known solutions employ so-called flow "deflection" techniques.
  • the deflection can be obtained by means of deflectors - i.e., protrusions - which force the flow to open in an "umbrella" shape, so that the product is conveyed on the inner walls of the receptacle, while the air is evacuated from the centre of the receptacle itself.
  • deflectors reduces the turbulence of the fluid during the filling, thus limiting the production of foam.
  • deflectors The main disadvantage of deflectors is related to the format change: to obtain a good deflection, the protrusions or teeth must be positioned at the connection area between the body of the bottle and the neck. The placement of the deflectors is thus variable as a function of the shape of the receptacle/bottle.
  • the deflection can be obtained by means of a helical element which usually envisages the return of air in a duct coaxial with the axis of the tap. With some types of taps, however, it is not possible to create a duct which crosses the shutter stem.
  • the transverse section of the duct has a disturbing effect on the vortex motion of the filling fluid.
  • a flow deflector in accordance with the preamble of claim 1 and with a central helical section is known from EP3670433 .
  • the deflector element is provided with protrusions or fins, in one of which an air evacuation duct extends.
  • the technical task underlying the present invention is to propose a flow deflector and a filling device for filling a receptacle comprising such a flow deflector, which overcome the problems of the prior art cited above.
  • Another object of the present invention is to provide a flow deflector which is compact and structurally simple.
  • a flow deflector for use in a filling device of a receptacle, in accordance with claim 1 and comprising a swirl body defining a first passage having a helical extension for a filling fluid.
  • the first passage consists of coils which impose a vortex motion on the filling fluid.
  • a second passage for a gas to be evacuated is also obtained in the swirl body.
  • the second passage is coaxial with the first passage and has an at least partially helical extension.
  • the second passage comprises a helically extending section defined by the outer walls of the coils.
  • the helically extending section of the second passage and the first passage are complementarily shaped to each other.
  • the second passage comprises a further cylindrical section which widens at one of the ends.
  • the coils are equally spaced by a predefined pitch.
  • the distance between the coils is variable.
  • the swirl body is made of stainless steel or titanium or of a polymer material.
  • a filling device for filling a receptacle comprising:
  • the flow deflector is removably inserted inside the valve body.
  • the flow deflector is housed in a lower zone of the valve body.
  • the number 1 indicates a flow deflector for use in a filling device 10 for filling a receptacle (not illustrated).
  • the flow deflector 1 comprises a swirl body 2 inside which a first passage 3 is obtained for a filling fluid, in particular a carbonated beverage.
  • the first passage 3 has a helical extension, i.e., it is formed by a plurality of coils 4 inside which the filling fluid flows.
  • the coils 4 impose a vortex motion on the fluid.
  • a second passage 5 for a gas to be evacuated is also obtained in the swirl body 2.
  • the second passage 5 is coaxial with the first passage 3.
  • the second passage 5 also has an at least partially helical extension.
  • the second passage 5 comprises a helically extending section 5a defined by the outer walls of the coils 4.
  • the first passage 3 and the helically extending section 5a of the second passage 5 are complementarily shaped.
  • the gas to be evacuated laps the outside of such coils 4.
  • the first passage 3 is characterised by a predefined pitch, i.e., by a predefined distance between the coils 4.
  • the pitch can be constant or variable.
  • the coils 4 of the first passage 3 all have the same diameter.
  • the second passage 5 comprises a further cylindrical section 5b which widens at one of the ends.
  • the swirl body 2 can be made of stainless steel or titanium or of a polymer material.
  • one or more coils 4 can have a greater diameter with respect to that of the other coils 4. Both the number of coils 4, and the pitch and the diameter of each coil 4 are parameters which are defined during the design phase, as a function of the filling fluid and the geometry of the receptacle.
  • the flow deflector 1 can be used inside a filling device 10 for filling a receptacle. See for example figure 3 .
  • the receptacle is a bottle having a tubular body and an externally threaded neck 100b.
  • the receptacle is made of thermoplastic material, such as PET.
  • the filling device 10 comprises:
  • the shutter 14 can be configured at least in:
  • the flow deflector 1 is housed in a lower zone of the valve body 11.
  • the flow deflector 1 is mounted integrally to the valve body 11.
  • the receptacle In order to be filled with a carbonated beverage, the receptacle is placed with the inlet 100c thereof in contact with the lower part of the filling device 10, in particular in contact with a sealing gasket.
  • the receptacle is then pressurised with carbon dioxide through the second passage 5 of the flow deflector 1.
  • the gas inside the receptacle is at the same pressure as the gas in the carbonated beverage.
  • the filling fluid is intercepted by the flow deflector 1.
  • the filling fluid is channelled into the first helically extending passage 3, which creates a vortex flow which is conveyed on the inner walls of the receptacle.
  • the helix geometry imposes a vortex motion on the fluid so that the velocity of the fluid has a tangential component which allows it to adhere to the inner walls of the receptacle.
  • the gas is evacuated through the second passage 5.
  • the gas travels through the first passage 5, crosses a plurality of openings 15 and reaches an annular chamber 16 obtained between the flow deflector 1 and the inner walls of the valve body 11.
  • An evacuation duct 17 obtained in the valve body 11 starts from the annular chamber 16. Since the first passage 3 and the second passage 5 are completely separate, the gas does not interfere with the beverage being dispensed, thus it does not disturb the vortex motion thereof.
  • the shutter 14 returns to the closing configuration which blocks the flow of the beverage to the dispensing nozzle 13.
  • the receptacle is depressurised, i.e., brought back to atmospheric pressure.
  • the receptacle is then lowered with respect to the filling device 10 and is ready to be closed by means of a capsule.
  • the flow deflector 1 is removably inserted inside the filling device 10 so that it can be replaced according to needs.
  • the appropriate flow deflector 1 is selected as a function of the filling fluid and the geometry of the receptacle.
  • the possibility of removing the flow deflector 1 allows to make the filling device 10 also suitable for filling flat drinks.
  • the flow deflector 1 is replaced by an element suitable for "flat" production.
  • the proposed deflector is compact in that the gas return path extends inside the swirl body, preferably in a complementarily shaped manner with respect to the dispensing path of the filling fluid. This therefore avoids providing further ducts for the exit of the gas, as is the case in some known solutions.
  • the return path of the gas in the swirl body is completely separated from that of the filling fluid, so the formation of foam is limited.
  • the flow deflector proposed herein is also used in aseptic packaging lines.
  • carbonated products are less sensitive to bacteriological contamination, for "sensitive" flat products such as isotonic drinks, juices, nectars, soft drinks, tea, milk-based drinks, coffee-based drinks, etc., it is essential to avoid any microbiological contamination.
