  • the invention relates to a method for a container treatment system as it can be used in container treatment machines in the beverage industry, in particular container treatment machines with outputs of more than 1000 containers per hour, in particular container treatment machines with an output of more than 10,000 containers per hour.
  • the invention relates to a method for a container treatment system which comprises a so-called filling machine or filler for filling the container with liquid filling material.
  • the invention also relates to a container treatment system which at the same time also includes the function of a closer for closing filled containers, and is designed in particular for closing filled containers with closure lids such as crown corks.
  • Filling machines of the type mentioned have a large number of treatment stations or positions which can also be understood as filling stations or filling positions.
  • a filling element or filling element with a filling valve or liquid valve is provided, via the discharge opening of which the liquid filling material is discharged into the container.
  • the filling material is dispensed into the container by means of what is known as “free jet filling”.
  • free-jet filling or “free-jet filling” is understood to mean a filling process in which the liquid filling material flows into the container to be filled from the liquid valve in a free filling jet or filling material jet, whereby the flow of the filling material does not pass through guide elements such as deflection screens, Swirl bodies, short or long filling tubes are influenced or changed. Free jet filling can take place both without pressure and under pressure. In the case of pressureless free-jet filling, the container has ambient pressure, the container generally not resting against the filling element with its container mouth or opening, but being spaced apart from the filling element or from a dispensing opening provided.
  • the container is in contact with the filling element with its container mouth, then it is a gas path establishes a connection between the interior of the container and the environment, which enables pressureless filling.
  • the gas contained in the container and displaced by the beverage flowing into the container preferably also escapes into the surroundings via this gas path.
  • the opening of the container is pressed against the filling element and sealed.
  • the pressure in the interior of the container is set to a pressure that corresponds to the ambient pressure or can differ from it by applying a tension gas or by applying a negative pressure.
  • the set pressure can be above or below the ambient pressure.
  • Closers of the type mentioned above generally also have a large number of treatment stations or positions which can also be understood as closing stations or closing positions.
  • a closing element or closing tool with a closing ram is provided, via which a crown cork is pressed onto the container mouth and finally fastened in a sealing manner by deformation.
  • a container treatment system for a beverage filling process is already known from the prior art, namely DE 10 2014 104 873 A1, in which a CO 2 -containing beverage is filled into an evacuated container, in particular a bottle.
  • the filling process takes place in a flash at very high speed, which means that it is not possible to relieve the container to the ambient pressure and / or to remove the container from the filling point, as this would inevitably lead to excessive foaming of the product .
  • the filling process is therefore combined with the closing process directly at the filling point.
  • the sealing process takes place in a closed gas space above the bottle and under a pressure above the CO2 saturation pressure.
  • the container to be filled can be flushed with an inert flushing gas before the actual evacuation.
  • CO2 is used as the inert gas both for flushing the container during a flushing phase and for introducing a tensioning gas after the filling phase used.
  • the use of CO2 is not only expensive, but its use is also increasingly the focus of an increasing environmental discussion in politics and business.
  • CO2 is an important part of the global carbon cycle and, as a natural component of the air, an important greenhouse gas in the earth's atmosphere: Human activities have increased its share in the earth's atmosphere since the beginning of industrialization. This increase causes an intensification of the greenhouse effect, which in turn is the cause of the current global warming.
  • the object of the invention is to provide a method both for filling containers with a liquid filling material and for closing the container with a closure lid, in which the use of CO2 is largely dispensed with.
  • the invention relates to a method for filling and closing containers on a filling and closing element of a treatment station, in which at least one container mouth of a corresponding container is connected to a process chamber of the filling and closing element in a pressure-tight manner.
  • At least the interior of the container arranged in a sealed position on the process chamber is initially evacuated at least once to a negative pressure of preferably 0.05 to 0.15 residual pressure in an evacuation phase and then in at least one rinsing phase with a steam and / or steam-containing purge gas is purged in such a way that the purge gas pressure in the container is increased to at least atmospheric pressure before the filling valve is opened to fill the container with the liquid filling material.
  • the filling valve is opened in the actual filling phase, so that the liquid filling material flows into the container, which is still arranged in a sealed position on the filling and closing element.
  • a treatment phase is carried out on the filling and closing element of the treatment station, in which the process chamber, in particular above the container mouth of the corresponding container, is preloaded by means of nitrogen to a pressure that is equal to the C02 saturation pressure of the CO2 or CO2 contained in the filled goods above it.
  • the container is closed on the filling and closing element of the treatment station by pressing on a closure cover at the pressure conditions set during the treatment phase, before the internal pressure of the process chamber is relieved to atmospheric pressure and the pressure-tight connection between the container mouth of the corresponding container and the process chamber is released becomes.
  • N 2 nitrogen (denoted by N 2 in the chemical formula) is used to pressurize the head space of the container and / or the treatment chamber after the container has been filled.
  • N2 can be obtained from the ambient air in the filling system, the steam used during the rinsing phase can be generated through the use of renewable energy sources.
  • the beverage is held in the container after the completion of the filling process and the release of the container mouth and before the closing process by an N2 excess pressure, which is preferably slightly above the saturation pressure of the CO2 contained in the filled product, whereby foaming of the product is also reliably prevented.
  • the N2 atmosphere also reliably prevents oxygen from penetrating the process chamber until the respective container is closed directly on or in the treatment station.
  • This shows a method for filling containers with a liquid product and also for closing the container with a closure lid, in which (method) the use of CO2 is significantly reduced or even completely eliminated compared to SdT.
  • the inventive method makes use of the principle that a carbonated drink, which by the action of vacuum or high Negative pressure was filled into a container at a very high filling speed, can then be relieved quickly after completion of the filling process if (excessive) foaming of the filling material is prevented by an increased ambient pressure, which is caused according to the invention by applying N2 to the process chamber.
  • the container in particular the bottle, is evacuated to a negative pressure of preferably 0.05-0.2 bar or 0.1-0.4 bar in an evacuation phase.
  • the container is then rinsed in a rinsing phase, in particular with superheated steam under vacuum, in order to remove the residual air as completely as possible.
  • the very pure vapor atmosphere in the container which is created in the preceding evacuation and rinsing phase and into which a drink is filled with a small amount of dissolved oxygen or other foreign gas, arises when the liquid contents are filled during the filling phase despite the strong influx caused by the rapid influx Flow turbulence, only very limited foam.
  • the carbonic acid that initially escaped from the drink as foam can be dissolved again very quickly in the drink.
  • the vapor pressure in the container is increased to atmospheric pressure or a pressure above it in the rinsing phase. If the filling valve then opens in the subsequent filling phase under these conditions, sudden condensation of at least part of the volume of the vapor located in the container occurs when the cold liquid filling material flows in. This causes a sudden filling of the container. If such an atmosphere is filled with high turbulence, there is initially a strong CO2 release and thus a transition of CO2 from the liquid to the gas phase. Caused by this effect and the residual gas atmosphere compressed by the cold filling material flowing in, the pressure in the container rises again.
  • the pressure in this filling phase exceeds the CO2 saturation pressure, re-carbonization takes place with the previously released CO2, i.e. the CO2 or carbonic acid is dissolved again in a flash in the drink as the pressure increases - up to or above the saturation pressure. Therefore, the foam formation generated remains within limits.
  • the steam purging process can be used to create an atmosphere in the container that is practically free of residual air (oxygen). With this method, too, the flow rate of the product into the bottle can be regulated using a combination of flow meter and control valve.
  • the required filling quantity of the filling material is dosed into a pre-vessel and suddenly discharged into the bottle. This is advantageous if the flow meter is no longer able to achieve sufficient measurement accuracy due to the high filling speed.
  • the beverage or filling material is preferably filled via a tight connection between a filling material vessel and the container to be filled by means of a switchable filling valve.
  • a pressure is preferably set in the gas space of the filling material container which corresponds to or is above the C02 saturation pressure of the liquid filling material to be filled.
  • the method has the advantage that the filling process takes place very quickly due to the large pressure difference between the tank and the container. This leads to short filling times and thus to filling machines with significantly smaller dimensions.
  • the filling speed can also be regulated via a control valve arranged in the inlet to the container as a function of the volume flow determined by the flow meter.
  • the pressure in the storage container can also be atmospheric pressure, or a pressure slightly higher.
  • Steam or superheated steam is preferably used as the flushing gas during the evacuation phase and / or during the flushing phase. This has the advantage that, on the one hand, any microorganisms in the container are killed before or during the filling process. On the other hand, the steam or the superheated steam condenses during the Filling suddenly, so that a vacuum filling is achieved. This leads to a very fast filling process.
  • an excess pressure of 0.02 to 0.2, in particular 0.05 to 0.1 bar can preferably also be set in the container after the rinsing phase and before the filling phase. This also means that when the drink is calming down, the pressure in the container or in the process chamber rises above the saturation pressure of the CO2 contained in the product, so that the drink does not degas or froth in the calming phase.
  • a treatment phase is carried out on the filling and closing element of the treatment station, in which the process chamber is pressurized with nitrogen N2, in particular above the container mouth of the corresponding container, and is thus pretensioned to a pressure which corresponds to the saturation pressure of the product being filled contained CO2 equals or exceeds.
  • the components of the filling and closing element that come into contact with the steam are made of a material with low thermal conductivity and / or heat capacity, so that the condensation effect is approximately is generated exclusively in the container.
  • a method in which the process chamber is set with a mixture of nitrogen and atmospheric air to a pressure that corresponds to or above the saturation pressure of the CO2 contained in the filled product.
  • a method in which the process chamber is set with pure nitrogen to a pressure which corresponds to or is higher than the saturation pressure of the CO2 contained in the filled product.
  • a method can be provided in which the evacuation phase and / or the flushing phase are each repeated several times can be carried out by alternately switching back and forth between the evacuation phase and the flushing phase.
  • nitrogen is added to the steam-containing purging gas of the purging phase, specifically preferably the final purging phase before the start of the filling phase.
  • a method in which at least the evacuation phase and / or the rinsing phase and / or the filling phase and / or the treatment phase are controlled and / or or is regulated.
  • the duration of the process steps of the evacuation phase and / or the rinsing phase and / or the treatment phase, in particular the rinsing of the container with steam between evacuation phases, the application of steam to atmospheric pressure shortly before the start of the filling phase and the application of steam to the process chamber the mouth of the container after the end of filling in the treatment phase can be kept as short as possible by the pressure-dependent switchover. In this way, the steam treatment times can be reduced to a minimum, depending on the pressure.
  • the pressure-dependent control and / or regulation can also reduce the amount of steam blown in and thus the energy input into the container to the necessary minimum.
  • the method steps immediately following the filling phase of pushing away the filling nozzle formed in the slide element and the actual closing of the container can also take place on the filling and closing element in the shortest possible process time.
  • a control loop is formed by means of which at least the evacuation phase and / or the flushing phase and / or the treatment phase are controlled and / or regulated as a function of the recorded actual pressure values, wherein the filling valve and / or at least one of the first to fifth control valves is provided as an actuator in the control loop.
  • the evacuation phase and / or the flushing phase and / or the Treatment phase can be controlled and / or regulated via preselectable pressure characteristics with the involvement of the control circuit.
  • the actual pressure values detected by the pressure sensor are transmitted to a machine control system and compared with the setpoint pressure values stored there and, based on this, the filling valve and / or at least one of the first to fifth control valves as Actuator are controlled.
  • setpoint pressure values are set that correspond to the respective actual pressure values of the evacuation phase currently being carried out and / or the The flushing phase and / or the treatment phase are compared and, when the target pressure values are reached, an immediate switchover from the currently performed evacuation phase to the currently performed, downstream evacuation phase and / or the flushing phase and / or the treatment phase is performed.
  • a switch is made from the current phase in the filling and sealing process to the current phase in the filling and sealing process, depending on the actual pressure values determined by the pressure sensor .
