Description
- The present invention relates to a flow deflector and a filling device for filling a receptacle comprising such a flow deflector.
- Among the known filling devices, a distinction must first be made according to the type of product:
- filling devices for so-called "flat" products, i.e., products without carbon dioxide;
- filling devices for carbonated products, i.e., products containing carbon dioxide.
- 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").
- Conversely, the filling of carbonated products occurs by contacting the filling valve with the receptacle. In fact, 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.
- In this context, attention is focused on filling carbonated products.
- A constraint in filling carbonated products is reducing or avoiding the formation of foam. To this end, some known solutions employ so-called flow "deflection" techniques. For example, 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. The use of deflectors reduces the turbulence of the fluid during the filling, thus limiting the production of foam.
- 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.
- Alternatively, 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.
- An example of a helical deflector, integral with the lower end of the shutter, is proposed in document
EP3473590 . The helices, lapped by the product, determine the rotation thereof, thus creating a vortex flow which is conveyed on the inner walls of the receptacle. The air is evacuated by means of a duct extending with an initial section centrally at the inlet of the receptacle, then deviating transversely with respect to the valve body and moving away with another section parallel to the valve body. - The transverse section of the duct has a disturbing effect on the vortex motion of the filling fluid.
- A deflector element 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. - In this context, 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.
- In particular, it is an object of the present invention to provide a flow deflector which allows the evacuation of the gas, avoiding or limiting interference with the vortex flow of the filling fluid.
- Another object of the present invention is to provide a flow deflector which is compact and structurally simple.
- The specified technical task and the specified objects are substantially achieved by a flow deflector for use in a filling device of a receptacle, 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.
- In accordance with an aspect of the invention, the second passage comprises a helically extending section defined by the outer walls of the coils.
- In accordance with a preferred embodiment, the helically extending section of the second passage and the first passage are complementarily shaped to each other.
- In accordance with an aspect of the invention, the second passage comprises a further cylindrical section which widens at one of the ends.
- In accordance with an embodiment, the coils are equally spaced by a predefined pitch.
- In accordance with another embodiment, the distance between the coils is variable.
- In accordance with an aspect of the invention, the swirl body is made of stainless steel or titanium or of a polymer material.
- The stated technical task and specified aims are substantially achieved by a filling device for filling a receptacle comprising:
- a valve body;
- a passage channel for the filling fluid, obtained inside the valve body;
- a dispensing nozzle for dispensing the filling fluid;
- a shutter slidably inserted into the passage channel to establish the selective communication thereof with the dispensing nozzle;
- the flow deflector in accordance with the present invention, which is arranged at the dispensing nozzle.
- In accordance with an aspect of the invention, the flow deflector is removably inserted inside the valve body.
- In accordance with an embodiment, the flow deflector is housed in a lower zone of the valve body.
- Additional features and advantages of the present invention will become more apparent from the illustrative and thus non-limiting description of a preferred but not exclusive embodiment of a flow deflector and a device for filling a receptacle comprising such a flow deflector, as illustrated in the appended drawings, in which:
-
figures 1A and 1B illustrate a flow deflector for use in a filling device, in accordance with the present invention, in two different perspective views; -
figure 2 illustrates the flow deflector offigure 1 in a sectioned perspective view; -
figure 3 illustrates a filling device, in accordance with the present invention, in a sectioned side view. - With reference to the figures, the
number 1 indicates a flow deflector for use in afilling device 10 for filling a receptacle (not illustrated). Theflow deflector 1 comprises aswirl body 2 inside which afirst 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 ofcoils 4 inside which the filling fluid flows. Thecoils 4 impose a vortex motion on the fluid. - A
second passage 5 for a gas to be evacuated is also obtained in theswirl body 2. - Advantageously, the
second passage 5 is coaxial with thefirst passage 3. In accordance with the embodiment described and illustrated herein, thesecond passage 5 also has an at least partially helical extension. Preferably, thesecond passage 5 comprises a helically extendingsection 5a defined by the outer walls of thecoils 4. - Preferably, the
first passage 3 and the helically extendingsection 5a of thesecond passage 5 are complementarily shaped. - In other words, while the filling fluid can flow inside the
coils 4 of thefirst passage 3, the gas to be evacuated laps the outside ofsuch coils 4. - In particular, the
first passage 3 is characterised by a predefined pitch, i.e., by a predefined distance between thecoils 4. - The pitch can be constant or variable.
- Precisely the distance between the
coils 4 allows to give rise to thesection 5a of thesecond passage 5 which extends as a helical path in the opposite direction with respect to thefirst passage 3. - In accordance with an embodiment of the invention, the
coils 4 of thefirst passage 3 all have the same diameter. - As visible in the figures, the
second passage 5 comprises a furthercylindrical 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. - In accordance with another embodiment, one or
more coils 4 can have a greater diameter with respect to that of theother coils 4. Both the number ofcoils 4, and the pitch and the diameter of eachcoil 4 are parameters which are defined during the design phase, as a function of the filling fluid and the geometry of the receptacle. - As mentioned above, the
flow deflector 1 can be used inside a fillingdevice 10 for filling a receptacle. See for examplefigure 3 . - In particular, the receptacle is a bottle having a tubular body and an externally threaded
neck 100b. - For example, the receptacle is made of thermoplastic material, such as PET.
- The filling
device 10 comprises: - a
valve body 11; - a
passage channel 12 for the filling fluid, obtained inside thevalve body 11; - a dispensing
nozzle 13 for dispensing the filling fluid; - a
shutter 14 slidably inserted into thepassage channel 12 to establish the selective communication thereof with the dispensingnozzle 13; - the
flow deflector 1 arranged at the dispensingnozzle 13. - In particular, the
shutter 14 can be configured at least in: - an opening configuration, in which it enables the flow of the filling fluid through the
passage channel 12 to the dispensingnozzle 13; - a closing configuration, in which the flow to the dispensing
nozzle 13 is blocked. - In accordance with an embodiment, the
flow deflector 1 is housed in a lower zone of thevalve body 11. - In particular, the
flow deflector 1 is mounted integrally to thevalve body 11. - The operation of the filling device for filling a receptacle, according to the present invention, is described below.
- 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 fillingdevice 10, in particular in contact with a sealing gasket. - The receptacle is then pressurised with carbon dioxide through the
second passage 5 of theflow deflector 1. At the end of the pressurisation, the gas inside the receptacle is at the same pressure as the gas in the carbonated beverage. - The
shutter 14, initially placed in the closing configuration, moves into the opening configuration for which it enables the flow through thepassage channel 12 to the dispensingnozzle 13. - At the dispensing nozzle, 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. In fact, 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. - During the filling, the gas is evacuated through the
second passage 5. In particular, the gas travels through thefirst passage 5, crosses a plurality ofopenings 15 and reaches anannular chamber 16 obtained between theflow deflector 1 and the inner walls of thevalve body 11. Anevacuation duct 17 obtained in thevalve body 11 starts from theannular chamber 16. Since thefirst passage 3 and thesecond passage 5 are completely separate, the gas does not interfere with the beverage being dispensed, thus it does not disturb the vortex motion thereof. - At the end of the filling, the
shutter 14 returns to the closing configuration which blocks the flow of the beverage to the dispensingnozzle 13. - At this point, 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. Advantageously, theflow deflector 1 is removably inserted inside the fillingdevice 10 so that it can be replaced according to needs. - For example, for carbonated productions the
appropriate flow deflector 1 is selected as a function of the filling fluid and the geometry of the receptacle. - Furthermore, the possibility of removing the
flow deflector 1 allows to make the fillingdevice 10 also suitable for filling flat drinks. In this case, theflow deflector 1 is replaced by an element suitable for "flat" production. From the description given, the features of the filling device of a flow deflector and a filling device for filling a receptacle comprising such a flow deflector according to the present invention appear clear, as do the advantages thereof. - In particular, 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. In particular, in some lines there is the need to fill both carbonated products and flat products. While 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.
Claims (11)
- A flow deflector (1) for use in a filling device (10) for filling a receptacle, comprising:
a swirl body (2) defining a first passage (3) having a helical extension for a filling fluid, said first passage (3) consisting of coils (4) that impose a vortex movement on the filling fluid,
