Definitions

  • the invention relates to a method according to the preamble of claim 1.
  • the object of the invention is to provide a method which optimally reconciles these aforementioned, sometimes contradicting requirements and ensures the lowest possible consumption of inert gas during filling with the lowest possible air and oxygen content in the prestressed container.
  • the respective container is rinsed in the pretreatment phase exclusively using steam (water vapor), with at least two or more rinses being carried out in succession, with each rinsing or before each introduction of the steam into the interior of the container being evacuated .
  • steam water vapor
  • This not only removes air and / or steam from the respective container interior, but in particular also ensures that a pressure prevails in the container after the evacuation, at which the evaporation temperature or saturated steam temperature is clearly below the temperature of the steam supplied during the treatment , for example in the range between 40 and 60 ° C, preferably around 45 ° C.
  • the container At the end of the pretreatment phase and before the container is pretensioned, it is evacuated again. With each evacuation, the respective container is preferably evacuated to approximately 90% of its total volume.
  • rinsing twice i.e. a double introduction of steam, each with a previous evacuation and a further evacuation following the second flush.
  • the container is then prestressed with inert gas, with a preferred embodiment of the invention first prestressing a partial prestress from the return gas collecting duct.
  • the method according to the invention ensures high concentrations of inert gas or small amounts of air and oxygen in the respective container during the actual process Filling, and with an extremely low consumption of inert gas, since this is only used for biasing. Due to the low consumption of inert gas, the filling costs and the emissions of inert gas to the atmosphere can be significantly reduced.
  • the amount of steam introduced into the container during rinsing is precisely controlled, preferably in a time-controlled manner and independently of the respective output with which the filling system is operated.
  • the amount of steam introduced into the container is therefore independent of the speed and power of this machine.
  • the cost of the amount of steam required for purging is much lower than the cost of a corresponding amount of inert gas.
  • 1 is a filling element which, together with a large number of identical filling elements, is provided on the circumference of a rotor 2 of a type that rotates around a vertical machine axis.
  • An annular bowl 3 which is common to all the filling elements 1 and also concentrically surrounds the vertical machine axis, is also provided on the rotor 2 and serves to receive and to supply the liquid filling material to the individual filling elements 1.
  • the ring bowl 3 is filled with this filling material up to a predetermined level N, in such a way that a gas space 5 is formed above the level N or the liquid space 4 occupied by the liquid filling material.
  • the ring bowl 3 or its liquid space 4 is connected to a line (not shown) for supplying the liquid filling material.
  • the gas space 5 is connected via a line, also not shown, to a source for an inert compressed gas (preferably CO 2 gas) such that the gas space 5 has a predetermined constant overpressure (filling pressure P1) when the filling machine is
  • the rotor 2 there is also a common return gas collecting channel 6, which serves in the manner described in more detail below, among other things, for receiving the CO2 gas displaced from these when filling the bottles 7 and in which a predetermined overpressure P2 is set.
  • the filling pressure P1 is, for example, 2 bar overpressure and the pressure P2 in the return gas collection channel 6 is about 1 bar overpressure.
  • a vacuum channel 8 common to all the filling elements 1, which is connected to a vacuum source via a line (not shown) and, for example, has a vacuum P3 of 0.9 bar, again in relation to the atmospheric pressure.
  • Each filling element 1 has a housing 9, in which a liquid channel 10 is formed, one end of which is connected to the liquid space 4 via an opening 11.
  • the other end of the liquid channel 10 forms an annular discharge opening 12 for the liquid filling material on the underside of the filling element 1 or the housing 9, which concentrically encloses a return gas pipe 13 ′ forming a return gas channel 13.
  • the return gas duct 13 is part of the gas path when brining, evacuating, prestressing, etc., as will be described below.
  • the probe 14 which determines the filling height is arranged in the usual way, in such a way that this probe, with its end having the probe contact 15, passes over the return gas pipe 13 'protrudes downwards and with its axis coaxially with the axis of the return gas pipe 13' or is arranged with the vertical filling element axis FA.
  • the liquid valve 16 is further provided in the usual way, which has a valve body 17 which, in the embodiment shown, is made in one piece with the return gas pipe 13 'and is raised by a predetermined stroke in the direction of the filler element axis FA between the raised and the liquid valve 16 and in the position shown in FIG. 1 and in a lowered position closing the liquid valve 16, by a pneumatic actuating device 18th
  • a centering tulip 19 is also provided, against which or the seal 20 the respective bottle 7 with its bottle mouth 7 'lies tight when filling and which in turn lies tight against the underside of the housing 9, so that when the bottle 7 is attached to the filling element 1, the interior of this bottle is sealed to the outside via the discharge opening 12 and communicates with the liquid channel 10.
  • the return gas pipe 13 'and the probe 14 also extend through the bottle mouth 7' into the interior of the bottle 7.
  • Each filling element 1 also has a control valve device, which in the embodiment shown consists of four individually controllable valves 21, 22, 23 and 35, which are designed as pneumatically actuable valves and are connected in the manner indicated below:
  • the space 25 communicates with the upper end of the annular return gas duct 13, which is formed within the return gas tube 13 'and surrounds the probe 14.

  • a channel 32 is also provided which connects the outlet of the valve 22 with the inlet of the valve 23, i.e. connects the channel 30 to the channel 29 and thus the return gas collection channel 6 to the space 25 and in which a ball or check valve 33 and a throttle 34 are arranged in series, namely the check valve 33 such that it closes when the Pressure in the room 25 is below the pressure P2 of the return gas collecting duct 6.
  • this check valve Since the pressure P4 in the steam channel 37 is lower than the pressure P2 in the return gas collection channel 6, this check valve has the advantage that the treatment of the respective bottle 7 with the steam, which will be described in more detail below, is possible without the need to separate the return gas. Collection channel 6 from the interior of the bottle 7 and a further controlled valve is necessary to prevent steam from entering the return gas collection channel 6. The design of the control valve device of the filling element is thus considerably simplified.
  • the respective bottle 7 is lifted from the lifting element assigned to each filling element 1, of which only the bottle plate 39 is shown in FIG. 1, from below in the usual way to the filling element 1 and with its bottle mouth 7 'in sealing position with the filling element 1 brought.
  • the valve 21 is then opened by the electronic control device 40, whereby a connection is established between the interior of the bottle 7 and the vacuum channel 8 for evacuating the bottle 7 via the channels 24 and 26, the space 25, the return gas channel 13 and the opened valve 21 becomes.
  • the check valve 33 is here in the closed position, since the pressure in the space 25 is significantly below the pressure P2 of the return gas collecting duct 6.
  • This process step which is shown in FIG. 2 in position a, is controlled in time and / or by the selection of the negative pressure P3 in the vacuum channel 8 such that a 90% vacuum is obtained in the respective bottle 7, i.e. only about 10% of the amount of air originally present in the bottle remained in the bottle.
  • bottle 7 is a 1.0 l bottle with a total volume of 1030 ml, at the end of this process step there is still approximately 103 ml of air in bottle 7, i.e. 927 ml of air were removed.
  • the valve 21 is closed again. Simultaneously or subsequently, the valve 35 opens, via which a connection between the steam channel 37 and the space 25 is then established, so that steam flows into the interior of the bottle 7 via the return gas pipe 13 'protruding into the bottle 7, for a first rinsing of this interior with the saturated steam.
  • the opening time of the valve 35 is preselected or controlled in such a way that an amount of steam is introduced into the bottle which is approximately a quarter of the total volume of the bottle, i.e. corresponds to about 250 ml.
  • the purging time can be varied by the control device 40, so that any amount of steam that can be increased in this first purging is also possible.
  • the check valve 33 is closed by the pressure difference present there between the pressure P2 of the return gas collecting duct 6 and the pressure in the interior of the bottle 7.
  • the pressure P2 is greater than the pressure P4 in the steam channel 37.
  • This first rinsing of the bottle is shown in position b of FIG. 2.
  • the valve 35 is closed again.
  • the valve 21 is opened and thus a connection between the interior of the bottle 7 and the vacuum channel is established.
  • the bottle 7 is thus evacuated again via the return gas duct 13 to a 90% vacuum, i.e. about 177 ml of steam and 73 ml of residual air are removed from the bottle as shown in position c of FIG. 2, so that about 73 ml of steam and 30 ml of air remain in the bottle.
  • valve 21 is closed.
  • saturated steam is again blown into the bottle 7 from the steam channel 37 via the return gas channel 13 again controls an amount of steam that corresponds to about a quarter of the total volume of the bottle, ie about 250 ml.
  • the amount of steam introduced is controlled again by controlling the opening time of valve 35. By increasing the opening or flushing time, the amount of steam introduced can be changed, for example, be enlarged.
  • This second rinsing also has the advantage that the saturated steam temperature is very low as a result of the preceding evacuation, so that the formation of condensate is avoided.
  • the valve 35 is closed again for the initiation of this method step, which can also be referred to as end evacuation of the bottle 7.
  • the valve 21 is opened again, as a result of which the interior of the bottle 7 is again connected to the vacuum channel 8 and the bottle 7 is evacuated via the return gas pipe 13 ′ to an approximately 90% vacuum.
  • This process step is shown in FIG. 2 in position e.
  • the valve 21 is closed in a time-controlled manner.

  • the interior of the bottle 7 is compared with the CO2 -, biased gas from the gas space 5, which also has a high concentration of CO2, and that is on the adjusted in the gas space 5 filling pressure P1, for example, an overpressure of 2.5 bar.
  • the check valve 33 opens, so that a throttled connection to the return gas collecting duct 6 results via this valve and the throttle 34.
  • the here over flowing during pretensioning amount of CO2 - but gas can be neglected, especially since this CO2 - gas from the return gas collecting duct 6 again for the partial tempering (step 6) is used.
  • the connection between the bottle 7 and the gas space 5 is interrupted by closing the valve 23.
  • the liquid valve 16 is opened.
  • the ball valve 33 remains open.
  • the throttle 34 provides a throttling of the displaced from the bottle 7 via the return gas passage 13 into the return gas collecting duct 6 CO2 - Gas flow, and thus for a gentle and slow Angioll Anlagen.
  • the filling speed actually achieved here results from the effective cross section of the throttle 34 and from the pressure difference between the pressures P1 and P2. These parameters can be set depending on the sensitivity of the product to be filled.
  • the duration of the filling phase is controlled by the control electronics 40 and is limited, for example, to a few 100 ms. Slow filling is not necessary for insensitive products.
  • the non-critical, cylindrical central region of the bottle 7 is filled at a high inflow or filling speed.
  • the valve 23 is opened, so that there is an unthrottled gas path into the gas space 5 via the return gas channel 13 and the opened valve 23, in addition to the gas path via the throttle 34, which results in a filling speed which is essentially through the static height difference between the level N of the product level in the ring bowl 3 and in the respective bottle 7 is determined.
  • the filling speed can be adapted to the requirements of the respective filling material and / or the shape of the respective bottle 7 via an automatic control of the level N.
  • the rapid filling phase is ended when the product level has reached the bottleneck that becomes narrower, controlled by the probe 14 or by a probe contact 15 provided at the lower end of this probe.
  • the rapid filling phase can also be terminated by the control electronics 40 in a time-controlled manner.
  • valve 23 is closed again, so that the same filling speed is established as for the slow filling.
  • the liquid valve 16 is closed in the usual manner, if appropriate after a preselectable or set correction time has elapsed.
