Definitions
- the invention relates to a method according to the preamble of claim 1 and to a treatment station according to the preamble of claim 12.
- metallic reusable KEGs which for filling with a liquid product, such as beer, wine, juice and / or water
- the temperature reached and sufficient for the sterilization of the reusable KEGs should be maintained as long as possible and as evenly as possible, so as to achieve optimum sterilization of the respective reusable KEGs and in particular the KEG inner surfaces.
- the sterile air and thus in particular also the oxygen contained in the sterile air displaced by the steam.
- the KEG interior Prior to filling or before preloading of the KEG interior which precedes the filling with a
- Biasing gas for example, with CO2 gas is carried out to complete the damping flushing of the respective KEG interior with an inert gas, for example with CO2 gas, so that vapor and condensate residues are removed from the KEG interior.
- steaming has heretofore been carried out so that, in a depressurized phase of steaming, steam is first blown through the KEG interior for several seconds, i. fed via a flow to the KEG interior and a return from the KEG interior together with
- Compression phase adjoins, in such a way that with continued to the KEG interior supplied pressurized steam, the outflow of water vapor from the KEG interior is interrupted by closing a return, so that builds up in the KEG interior, a water vapor pressure.
- the KEG interior is then separated from the water vapor supply or the water vapor source during this pressure phase of the damping and kept in this state for a period of time (holding or exposure time), until condensation of the water vapor on the inner surfaces of the reusable KEG has sufficiently heated it with respect to temperature and time duration and the pressure in the KEG interior has reduced due to the condensation of the water vapor.
- the Duration of this exposure time is for example 60 to 90 seconds, in special cases, from less than 10 to more than 90 seconds. This is followed by the already mentioned rinsing or blowing out of steam and condensate residues with an inert gas, for example CO2 gas.
- a disadvantage of the known methods is, inter alia, that in the pressureless phase in the blowing of the KEGs with water vapor is consumed a lot of energy and yet only insufficient heating of the KEG inner surfaces is achieved, which is not even sure that this is a heating all for the
- a disadvantage of known methods further, which is in the pressure phase of damping and in particular during the holding or exposure time in which the at least initially pressurized KEG interior is separated from the steam supply, the KEG inner surfaces occupied very quickly by forming condensate which then hampers the energy conversion or heating in the areas concerned.
- the same disadvantage results from the condensate collecting in the lower region of the KEG interior during the exposure time.
- the object of the invention is to provide a method which avoids the aforementioned disadvantages and enables improved sterilization of KEGs, in particular of reusable KEGs and especially of those made of metal, with reduced water vapor and energy consumption and reduced treatment time.
- a treatment station is the subject of claim 12.
- the preferred field of application of the invention is the heating and sterilization of reusable KEGs.
- the invention also finds application in KEGs in general as well as in the first use of previously unused KEGs or reusable KEGs, i. before the first filling of these unused KEGs or reusable KEGs. Steaming takes place at least for reusable KEGs after a KEG interior cleaning.
- the overall result is a reduction of the steam and energy consumption and a reduction in the water consumption and energy consumption without impairing the desired heating of the respective KEG and thus without impairing the quality of the sterilization of the respective KEG the heating necessary treatment time.
- the latter then also allows a considerable increase in the performance of a machine or plant for treatment or cleaning,
- the relative movement between the water vapor and the inner surfaces of the KEG interior can be produced in various ways, for example by virtue of the fact that, at least during the exposure or holding time, ie when the water vapor Supply of separate KEG interior of the local water vapor is circulated, by discharging the water vapor from the KEG interior and again feeding the water vapor into the KEG interior in a closed
- the relative motion between the water vapor in the KEG interior and the interior surfaces of the KEG can also be generated mechanically, for example, by movement of the KEG, e.g. by rotation, by pushing or shaking, by, for example, multiple acceleration and deceleration of the KEG, etc.
- this mechanical movement of the KEG can also be combined with the circulation of the water vapor generating the relative movement.
- the figure shows in a simplified schematic functional representation by way of example a treatment position 1 of an otherwise not shown machine or system for emptying, cleaning, sterilization and subsequent filling of reusable KEGs or reusable KEGs 2, in particular of metallic reusable KEGs with a liquid product, for example with drinks, such as beer, wine, juice, water etc.
- a treatment or cleaning head 3 which has, for example, the known to those skilled in KEG treatment systems constructive training, the turned, ie with its KEG fitting 4 facing down and arranged in sealing position on the treatment head KEG 2 and the the heating of the KEG 2 or the KEG wall and the KEG fitting 4 necessary functional elements of the treatment position.
- Treatment head 3 connects, as well as a line 8 with control valve 9, which connects a return port 3.2 of the treatment head 3 with a liquid separator 10, for example in the form of a cyclone.
- the liquid separator 10 is used in particular during the depressurized phase of damping for separating liquid, in particular for separating off condensate, which has arisen on heating and sterilizing the KEG interior 2.1 and the inner surfaces of the KEG 2 and the KEG fitting 4 by condensation of the vapor ,
- the condensate is discharged in the illustrated embodiment via the line 8, in a gully 1. 1
- a bypass line is referred to, which extends between the lines 5 and 8 and in the u.a.
- a circulation or vapor pump 13 is preferably arranged in series with two control valves 14 and 15, of which the control valve 14 at the inlet and the control valve 15 at the outlet of the vapor pump 13 are located.
- Control valve 6 following. Based on a flow direction from the return port 3.2 to the liquid separator 10, the connection of the bypass line 12 is located in front of the control valve. 9
- the flow connection 3.1 With the flow line of the treatment head 3 and the KEG fitting 4 open, the flow connection 3.1 is connected to the riser 4.1 of the KEG fitting 4, so that water vapor supplied via the flow connection 3.1 can escape into the interior space 2.1 at the upper end of the riser 4 , as indicated in the figure by the arrows A.
- the return connection 3.2 With the return of the treatment head 3 and the KEG fitting 4 open, the return connection 3.2 is at the bottom of the turned returnable KEGs 2 formed by the KEG fitting 4 return opening so that water vapor, but also steam condensate can be removed via this return opening and the return port 3.2 of the treatment head 3, as indicated in the figure with the arrows B.
- the figure shows only the functional elements necessary for damping, but not functional elements required for other treatment steps, which are also associated with the treatment head 3, e.g.
- the heating and sterilization of the respective, arranged in sealing position on the treatment head 3 reusable KEGs 2 takes place after completion of internal cleaning and after removing and expressing the treatment medium used for internal cleaning so that with closed control valves 14 and 15 and not activated steam pump 13, the is formed, for example, in the manner of a blower or fan, but with open control valves 6 and 9 and with open flow and return of the treatment head 3 and the fitting 4, a short blowing of the KEG interior 2.1 is carried out with water vapor.
- the steam is supplied at a temperature not higher than 135 ° C under pressure from the steam inlet 7 via line 5 and the open control valve 6 to the flow connection 3.1, then exits at the upper end of the riser 4.1 (arrows A) and is after flowing through the KEG interior 2.1 together with possibly accumulated condensate on the
- Locking treatment head 3 and 4 of the fitting so that in further connected to the steam inlet 7 via the open line 5 flow of the
- Treatment head 3 and the KEG fitting 4 is increasing
- This relative movement has a decisive one
- the relative movement between the water vapor and the inner surfaces of the KEG 2 and the KEG fitting 4 during the pressure phase of damping can also be generated in other ways, for example, that the reusable KEG 2 is mechanically moved during this printing phase, for example in one repeatedly carried out acceleration and braking movement, in a shock or shaking movement and / or in a rotary or rotary or Schenkterrorism preferably about its central axis MA, which is also the central axis of the treatment head 3 and the riser 4.1 in the illustrated embodiment.
- the treatment position 1 then has a mechanical drive, which acts on the reusable KEG 2 and is indicated schematically in the figure by 17.
