  • a pourable food product e.g. a carbonated pourable food product such as beer or mineral water.
  • Filling machines comprising a filling station, which is fed at the input with empty containers, and supplies at the output containers filled with the pourable food product.
  • the filling station substantially comprises a carousel conveyor rotating about an axis of rotation; a tank containing the pourable food product; and a number of filling valves connected fluidically to the tank and fitted to the conveyor, radially outwards of the axis of rotation of the conveyor.
  • the conveyor comprises a number of container supports for positioning the mouths of the containers beneath the respective valves, and for moving the containers along an arc-shaped path about the axis of rotation and integrally with the respective valves .
  • Each filling valve substantially comprises a fastening body for attachment to the conveyor and defining a filling chamber connected fluidically to the tank; and a filling head that moves to and from the fastening body in a respective direction parallel to the axis of rotation of the conveyor, to move to and from the relative container.
  • Each filling head comprises a stopper movable inside the chamber between a closed position cutting off flow of the pourable food product to the mouth of the relative container, and an open position connecting the chamber fluidically to the mouth to allow flow of the food product into the container .

  • a probe e.g. an inductive probe
  • each container When filling containers with a carbonated pourable food product, each container is first pressurized to the same pressure as the pourable food product during the filling process. More specifically, the container is pressurized by feeding a fluid, e.g. carbon dioxide, into it, with the filling head stopper in the closed position. The stopper of the relative filling valve is then moved to the open position, and the container is filled. Filling comprises a fast first step and a slow second step immediately after the first step. The first filling step terminates when the pourable food product level reaches the height of the probe.
  • a fluid e.g. carbon dioxide
  • the slow second filling step starts upon the pourable food product level reaching the probe, and continues as long as necessary to fill the container with a given amount of pourable food product.
  • each container is depressurized so the pressure above the pourable food product level equals atmospheric pressure. Depressurization is performed by removing the carbon dioxide used to pressurize the container.
  • a drawback of filling valves of the type described above is that, given the position of the probe projecting inside the container, explosion of or damage to the container during the filling process may easily result in damage to the probe, thus resulting in stoppage of the filling machine.

  • Filling valve 1 therefore comprises a first flow line - defined by first tank 3 and cavity 17 connectable selectively by stopper means 12 to mouth 5 of container 2, and which serves to fill container 2 with the pourable food product.
  • Filling valve 1 also comprises a second flow line - defined by conduits 32, 40, pipes 50, 51, control valves 53, 54, and conduits 57, 58 - along which travel the carbon dioxide flowing into container 2 to pressurize it before it is filled with the pourable food product, and at least part of the carbon dioxide issuing from container 2 when filling it.
  • Filling valve 1 advantageously comprises sensor means 60 which interact with the carbon dioxide along the second flow line to measure a carbon dioxide parameter and determine when the pourable food product inside container 2 reaches a predetermined level. More specifically, sensor means 60 comprise a flow switch 61 associated with inside portion 36 of conduit 32.
  • the term "flow switch" is intended here to mean a device for determining flow or not of a fluid inside a conduit .
  • flow switch 61 detects the interruption in carbon dioxide flow inside portion 36, when the pourable food product, once container 2 is filled, flows back up along conduit 32 to a height Q with respect to a fixed reference, and with control valve 53 in the open position and control valves 54, 55 in the closed position ( Figure 4) .
  • Height Q corresponds to the hydrostatic pressure of the pourable food product in first tank 3.
  • the pourable food product flows back up along conduit 32 until it reaches height Q, at which the hydraulic head of the pourable food product in conduit 32 equals that of the pourable food product in first tank 3.
  • the pourable food product is at the same height Q in first tank 3 and conduit 32.
  • flow switch 61 may be replaced by a flow meter, i.e. a device for measuring carbon dioxide flow along portion 36.
  • a flow meter i.e. a device for measuring carbon dioxide flow along portion 36.
  • filling valve 1 Operation of filling valve 1 will be described as of the Figure 1 condition, in which mouth 5 of container 2 rests against seal 21, control valves 53, 54 are open, control valve 55 is closed, and stopper means 12 are in the closed position.
  • control valves 54, 55 being closed, carbon dioxide is prevented from escaping from container 2 along conduits 40, 41 or 40, 42, and can only escape along conduit 32. More specifically, the pourable food product is caused to flow back up by the hydrostatic pressure of the pourable food product in first tank 3 , and therefore flows back up along conduit 32 to height Q, at which the hydraulic head of the pourable food product in conduit 32 equals that of the pourable food product in first tank 3. More specifically, when carbon dioxide pressure is the same in conduit 32 and first tank 3, the pourable food product is at the same height Q in first tank- 3 and conduit 32.
  • Flow switch 61 detects the stoppage in carbon dioxide flow caused by the pourable food product reaching a given level in container 2 , and generates a signal to command actuator 24 to move stopper means 12 into the closed position after a given time interval from when flow switch 61 detects the pourable food product has reached height Q in conduit 32.
  • the time interval is calculated to fill container 2 with a given amount of pourable food product.
  • stopper means 12 is lowered into the closed position, control valve 54 is closed, and control valve 55 is opened to allow the carbon dioxide in conduits 40, 42 to escape into second tank 4 and complete decompression of container 2.
  • filling valve 1 operates in exactly the same way, by the flow meter recording zero carbon dioxide flow along portion 36.
  • Number 1' in Figure 7 indicates a filling valve in accordance with a further embodiment of the invention.
  • Filling valve 1' is similar to filling valve 1, and is described below only as regards the differences between the two, and using the same reference numbers, where possible, for corresponding or equivalent parts of filling valves 1 and 1'.
  • Filling valve 1' differs from filling valve 1 by sensor means 60' comprising, as opposed to flow switch 61, a pressure switch 61', which, instead of being associated with conduit 32, is associated with conduit 42, so that said pressure switch 61' can determine the variation in pressure in conduit 42 when the pourable food product level in container 2 reaches opening 33 of conduit 32.
  • control valve 53 When the pourable food product level in container 2 is below opening 33 at the slow filling stage, control valve 53 is open, and control valves 54, 55 are closed ( Figure 3) .
  • pressure switch 61' determines the difference between the first and second pressure value, and generates a signal to command actuator 24 to move stopper means 12 into the closed position after a given time interval from when flow switch 61' detects the difference in pressure.
  • the time interval is calculated to fill container 2 with a given amount of pourable food product .
  • pressure switch 61' is calibrated to determine a predetermined difference between the first and second pressure value, indicating the pourable food product has reached a given height inside conduit 32.
  • filling valves 1, 1' provide for determining when the pourable food product reaches a given level inside container 2 by measuring, by means of a flow switch 61, a flow meter, or a pressure switch
  • Filling valves 1, 1' therefore do not need a probe to determine the level of the pourable food product inside container 2.
  • Filling valves 1, 1' therefore have no fragile parts exposed inside container 2, and which could be damaged in the event of container 2 bursting.
  • flow switch 61 or the flow meter may be calibrated to determine a difference in flow along portion 36, indicating a height lower than height Q of the pourable food product along conduit 32.
