Definitions

  • the present invention relates to a device for filling a container with a filling product, preferably in a beverage filling plant, and a method for cleaning and / or sterilizing such a device.
  • the container can according to one in the DE 10 2014 104 873 A1 described further development are sealed under overpressure, without a pressure equalization of the container interior with the external environment taking place beforehand.
  • the container mouth is placed in a chamber for filling and closing, and the chamber is brought to the above-mentioned overpressure. Only after the container has been closed is the chamber released to atmospheric pressure in order to be able to remove the container.
  • the pressure level in the chamber surrounding the container mouth is detected and recorded with a pressure sensor.
  • the system and method for sudden filling manage without a flow meter at the individual filling stations, since the filling can be regulated by the vacuum pressure level in the evacuated container and the filling pressure.
  • the SIP process is subsumed under the CIP process, i.e. the CIP process includes cleaning and / or sterilization.
  • the surfaces of the filling system that come into contact with the filling product can be thermally sterilized by means of superheated steam.
  • the filling valves are exposed to superheated steam and brought to the sterilization temperature in this way.
  • the temperature of the filling valves resulting therefrom is maintained and monitored over a certain period of time in order to achieve a predetermined sterilization effect, as can be seen, for example, from the DE 10 2010 031 873 A1 or the DE 10 2013 113 621 A1 is known.
  • thermocouple which is usually integrated in the filling valve or arranged on the panel.
  • thermocouple is usually integrated in the filling valve or arranged on the panel.
  • thermocouple per filling valve or per diaphragm and correspondingly complex wiring, which is installed in the rotating part of rotary machines.
  • An alternative temperature monitoring of the filling valves during the sterilization by means of a contactless temperature sensor is from the WO 2018/104551 A1 known.
  • the filling / closing system described at the beginning requires comparatively few sensors to monitor the filling process; In particular, there is no need for a flow meter, since the filling can be regulated by the vacuum pressure level in the evacuated container and the filling pressure.
  • a validation of the cleaning or sterilization is therefore not easily possible by detecting and recording the volume flow of the cleaning or sterilization medium by means of flow meters.
  • the device according to the invention also referred to herein as a "filling device", is used to fill a container with a filling product.
  • the device is particularly preferably used in a beverage filling system for filling beverages - such as, for example, water, carbonized or non-carbonized, soft drinks, beer or mixed drinks.
  • the filling device has at least one filling station with a filling element for introducing the filling product into the container to be filled and a treatment device for treating components of the device that come into contact with the filling product by means of a treatment medium.
  • a treatment device for treating components of the device that come into contact with the filling product by means of a treatment medium.
  • components of the filling element such as, for example, filling valve, product line, gas lines, gas valves and the like.
  • the treatment device primarily serves to clean and / or sterilize product-carrying / product-carrying components of the device.
  • the device has at least one pressure determination device for detecting pressures of the treatment medium at one or more points on the device on.
  • the pressure of the treatment medium is thus determined at one or more points of the fluid-carrying components of the device, ie in lines, chambers, valves, etc.
  • the phrase “recording pressures” includes a direct measurement of the pressures in customary physical units as well as the determination or derivation of alternative parameters that can be used as an alternative measure for the pressure.
  • the terms “pressure”, “pressures” etc. also include not only absolute pressure values, but also pressure changes and in particular equivalent physical quantities which, although not necessarily measured in typical units of pressure, are a measure of the pressure.
  • the pressure determination device can comprise a pressure sensor, pressure transducer or the like, but it can also implement a device for indirect determination of the pressure, for example by evaluating other physical variables. Examples of such an indirect pressure determination are presented in detail with the aid of the description of preferred embodiments.
  • the device also has an evaluation device which is set up to receive the pressures detected by the pressure determination device during the treatment of the device (this can be done wirelessly or wired) and to determine from this whether the device has been adequately treated.
  • the evaluation device monitors and / or verifies the treatment on the basis of the determined pressures of the treatment medium.
  • the success of the treatment can also be verified without the use of flow meters. No additional measuring equipment is necessary.
  • the pressure can be determined directly via pressure sensors or pressure sensors or indirectly, for example by synergetic use of the equipment of the filling device. The verification or monitoring thus takes place in a structurally and procedurally particularly simple, autarkic and reliable manner.
  • At least two pressure determination devices are preferably provided for detecting pressures of the treatment medium at at least two different points on the device, the evaluation device in this case being set up to receive the pressures detected by the pressure determination devices during treatment of the device and to determine them from a comparison whether the device has been adequately treated.
  • the comparison can be made by forming the difference. In this way, the pressure drop between two points of the device can be used to infer irregularities, for example insufficient flow through sections of the device.
  • the device preferably has a product vessel in fluid connection with the filling element, the at least one pressure determination device being set up to detect pressures of the treatment medium in the product vessel and / or in the filling element or in a treatment chamber surrounding the filling element.
  • Pressure sensors or equivalent devices are usually installed in the product tank and / or in the filling element or a treatment chamber surrounding the filling element for the regular operation of the filling device anyway, which can then be used synergistically for the treatment operation, which further simplifies the device in terms of mechanical engineering and further increases the reliability of the same becomes.
  • the structure and the nature of a treatment chamber which is preferably provided are set out in detail below.
  • One of the pressure determination devices is preferably set up to detect pressures in the product vessel and another of the pressure determination devices is set up to detect pressures of the treatment medium in the filling element or in a treatment chamber surrounding the filling element.
  • the monitoring or verification of the treatment is possible in a particularly efficient way from a mechanical engineering point of view if pressures in the product tank and in filling organs or any treatment chambers of the filling stations are used for this purpose. For example, if the pressure drop between the product vessel and the filling element or the treatment chamber is too high, when the filling valve is open, conclusions can be drawn that there is too little or no flow and thus an inadequate treatment effect. This observation, in turn, can be used for the early detection of a possible later failure.
  • the filling station preferably has a treatment chamber for receiving the container to be filled in a sealed manner, either completely or in sections. Furthermore, a component sealing the treatment chamber and movable relative to the treatment chamber by means of a drive and protruding into the treatment chamber is preferably provided, in this component If the at least one pressure determination device or one of the pressure determination devices is set up to detect pressures of the treatment medium in the treatment chamber.
  • the treatment verification presented here is particularly suitable for filling devices that are set up for the sudden filling of containers or for "overpressure filling".
  • the container or at least the container mouth, is introduced into the said treatment chamber for filling and, if necessary, for closing, it being possible to regulate the pressure in the treatment chamber.
  • the device is preferably set up for filling and closing the container, in this case also referred to herein as "filler / closer", each filling station in this case preferably having: a treatment chamber which is set up to at least partially surround the container, preferably an opening section of the container, and which is sealable from the external environment; the filling element, which is set up in the treatment chamber for evacuating the container and introducing the filling product into the evacuated container, the filling product preferably being under excess pressure; and a closure member with a closure head which is set up to receive a closure and to close the container in the treatment chamber and without prior release to ambient pressure with the closure.
  • the closer head is preferably movable between a retracted position, also referred to as a "sealing position", and an advanced closing position in which the closer head protrudes into the treatment chamber.
  • evacuation does not necessarily imply an endeavor to bring the negative pressure in the container as close as possible to a perfect vacuum. Rather, the evacuation can serve to build up a specific negative pressure.
  • underpressure and "overpressure” are initially to be understood relative to one another.
  • the overpressure of the filling product under which the filling is carried out can correspond to atmospheric pressure, but is preferably higher.
  • a negative pressure can also be a pressure which is above atmospheric pressure. Evacuating the container to this pressure can therefore also correspond to an increase in the pressure relative to the environment, in which case an atmosphere is preferably provided in the container which then corresponds to a defined amount of carbon dioxide.
  • the gas providing the negative pressure in the container is preferably mainly carbon dioxide.
  • the container before the filling product is introduced, the container is preferably evacuated to a negative pressure P low with an absolute pressure of 0.5 to 0.05 bar, preferably 0.3 to 0.1 bar, particularly preferably about 0.1 bar.
  • the overpressure is preferably above atmospheric pressure, for example at an absolute pressure of 1.1 bar to 6 bar.
  • the container is preferably evacuated in such a way that essentially no gas is displaced by the filling product when it is filled with the filling product and, accordingly, no gas has to flow out of the interior of the container. Rather, the entire mouth cross-section of the container can be used to introduce the filling product. In other words, during filling there is only one flow of filling product directed into the container, but no opposing flow of fluid.
  • the negative pressure in the container which is preferably built up essentially by gaseous carbon dioxide, can, however, also be above atmospheric pressure, for example at an absolute pressure of 1.1 to 2 bar.
  • the overpressure is then above the respective negative pressure and particularly preferably 1 to 5 bar above the respective negative pressure, that is to say, for example, at an absolute pressure of 2.2 to 7 bar.
  • the container is filled suddenly and it is closed in a temporally and spatially integrated and therefore extremely hygienic manner.
  • the filling element preferably has an opening section, the filling being carried out in this case in such a way that the opening section for filling the container is brought into sealing fluid communication therewith in the treatment chamber, the treatment chamber is sealed off from the external environment and brought to an overpressure, and the mouth section is released from the container after the filling process has ended, whereby the overpressure of the treatment chamber acts on the filling product in the container.
  • the container is filled suddenly, while at the same time foaming over after filling, in particular after removing the filling element from the container mouth, is prevented.
  • the verification of the cleaning and / or sterilization of the filling elements presented here is particularly suitable for fillers / closers, in particular for sudden filling, since the complex structure of the filling stations, including the filling element and the closer, makes conventional monitoring by means of a flow meter difficult. According to the pressure-based verification of the Treatment does not have to rely on a flow measurement of the treatment medium.
  • the pressure determination device is preferably set up to determine a pressure of the treatment medium present in the treatment chamber by determining a manipulated variable of the drive of the movable component, the drive preferably comprising an electric linear motor and the manipulated variable corresponding to a current strength and / or voltage supplied to the drive.

  • the pressure present in the treatment chamber can be determined without a pressure sensor having to be provided in the treatment chamber, which would otherwise mean an additional built-in part that would have to be electrically supplied, read out and placed.
  • the pressure sensor would still have to be hygienic so that it cannot contaminate the filling product.
  • the drive is used here synergistically to determine the pressure in the treatment chamber.
  • the manipulated variable is preferably proportional to a holding force of the drive for holding the component in a predetermined position. This is particularly the case when the component and its drive are in principle freely movable due to the pressure in the treatment chamber and the drive must accordingly apply a holding force to hold the position of the component. This holding force is expressed accordingly by the manipulated variable to be applied.
  • the movable component preferably comprises the filling element, which is particularly preferably set up for sealing application to the container sealed with the treatment chamber and for introducing the filling product into the container.
  • the movable component comprises a closure member for applying a container closure to a filled container within the treatment chamber.

  • a boiler pressure determination device 41 is installed on the product boiler 40 and is set up to determine the pressure in the product boiler 40.
  • the boiler pressure determination device 41 comprises a pressure sensor, but it can also be another device that is capable of directly or indirectly determining the pressure in the product boiler 40, for example by evaluating other physical variables, as described below with reference to the ones described below Treatment chamber pressure is set out.
  • a chamber pressure determination device 11, which is set up to determine the pressure in the treatment chamber 10, is installed on the treatment chamber 10.
  • the chamber pressure determination device 41 comprises a pressure sensor, but it can also be another device which is capable of directly or indirectly determining the pressure in the treatment chamber 10.
  • the chamber pressure determination device 11 can be set up and designed to determine the pressure present in the treatment chamber 10 by determining the manipulated variable of a drive 32 of the closure member 30, since the closure member 30 controls the treatment chamber 10 in addition to any CIP cap 42 that is attached to the container side Closing of the treatment chamber 10 or a return line 43 is set up, is sealed from above and can be moved back and forth between a sealing and closing position during the treatment, as set out above in relation to the process of closing a container.
  • This functionality which initially relates to regular operation, can now be used synergistically to determine the pressure in the treatment chamber 10.
  • the closing member 30 is viewed as a piston on which the pressure present in the treatment chamber 10 acts.
  • the manipulated variable is thus proportional to a holding force of the drive 32 for holding the closing element 30 in a predetermined position.
  • the drive 32 of the closing element 30 is controlled in such a way that the closing element 30 is held in a predetermined position.
  • a pressure change in the treatment chamber 10 acts directly on an end face of the closure member 30. Therefore, based on the pressure change in the interior of the treatment chamber 10, there is a resulting force on the closure member 30.
  • a corresponding holding force must be applied the drive 32 are provided.
  • the manipulated variable consequently corresponds to a current intensity and / or voltage supplied to the drive 32.
  • the one to comply with the The change in the current intensity required for a given position is proportional to a change in pressure in the sealed treatment chamber 10.
  • the determined manipulated variable can be compared, for example, with values from a look-up table.
  • the pressure can be determined from the result of a predetermined function as a function of the determined manipulated variable.
  • another algorithm or artificial intelligence can also be used to determine the pressure in the treatment chamber 10.
  • the chamber pressure determination device 11 can determine the pressure in the treatment chamber 10 even without a pressure sensor.
  • the displaceable filling element 30, its drive 32 and any electronic control device assume the function of a pressure sensor.
  • the pressure in the treatment chamber 10 can alternatively or additionally also be measured by a pressure sensor in the treatment chamber 10, in the mouth area of the filling element 20 or at another suitable point.
  • the chamber pressure determination device 11 and the boiler pressure determination device 41 as well as any other sensors or electronic devices, such as the drive 32 or an ammeter connected to it, are communicatively connected to an evaluation device 44, which is an electronic device for monitoring and / or controlling the treatment process.
  • the data transfer can be wireless or wired.
  • the treatment medium runs from the product vessel 40 via the filling product line 22 to the filling element 20.
  • the gas line 24 and the treatment chamber 10 are also flushed through or treated with the treatment medium.
  • the treatment medium is transported away via the return line 43, to which, for example, a negative pressure is applied.
  • the removed treatment medium can be disposed of or prepared for complete or partial reuse.
  • pressures are determined and evaluated at different points in the filling device 1.
  • the pressures in the product vessel 40 and in the treatment chamber 10, which can be measured or otherwise determined as set out above, are particularly preferably used here.
  • the pressure in the product vessel 40 can be compared with the pressure in the treatment chamber 10.
  • different pressure states can be recorded and evaluated.
  • these pressure states can be recorded and evaluated as a function of the angle, in that the rotary carousel rotates during the treatment and all or some inlet and outlet valves are repeatedly switched.
  • the system sections of the filling device 1 to be treated are filled with treatment medium and flushed through, so that the treatment medium runs or flows in a treatment circuit.
  • a volume flow of the treatment medium is provided via the product lines 22, the product boiler 40, the filling elements 20, any gas lines 23 and gas valves 24 and the return line 43.
  • the pressure determination and evaluation can take place at the time of the pressure change over the various angles of the carousel.
  • a threshold value, a characteristic curve or the like for comparison with the determined pressure states during the treatment can be used by the Evaluation device 44 can be used.
  • the success of the treatment can also be verified without the use of flow meters. This is possible in a particularly efficient manner in terms of mechanical engineering if the pressures in the product vessel 40 and in the treatment chambers 10 of the filling stations are used for this purpose. No additional measuring equipment is necessary.
  • the pressure can be determined directly via pressure sensors or pressure sensors or indirectly through synergetic use of the equipment in the filling device 1, for example by evaluating the power consumption of the drive 32 of the closing element 30.
