Opfindelsen angår en fremgangsmåde til sterilisering af emballage, navnlig beholdere, som er forudformede fra tilskirne stykker, og som er beregnet til flydende påfyldningsmateriale, ved hvilken fremgangsmåde den emballageflade, der skal steriliseres, 5 tilføres hed damp og syre.The invention relates to a method of sterilizing packaging, in particular containers pre-formed from cut pieces, which is intended for liquid filling material, by which method the packaging surface to be sterilized is supplied with hot steam and acid.
Det har længe været kendt at sterilisere materiale af den forskelligste slags ved hjælp af overhedet damp. En virksom sterilisering af emballage ved hjælp af overhedet damp, hvad enten emballagen foreligger i form af baner, f.eks. af plastfolie eller af 10 plastlamineret karton, eller i form af allerede færdige beholdere, f.eks. fremstillet af kartontilskæringer, inden for den til automatisk aftapning nødvendige korte steriliseringstid af en størrelsesorden på få sekunder, kan imidlertid kun opnås ved anvendelse af temperaturer i området fra ca. 125 til 150°C. Dette indebærer, at sterili-15 sering må foretages ved forhøjet tryk af en størrelsesorden på fra 2,4 til 5 bar. Men herved forøges den til sterilisering nødvendige udgift i betragtelig grad, da det steriliseringsanlæg, hvorigennem emballagen skal føres, må gøres tæt overfor omgivelserne og være beregnet til forhøjet tryk. Ydermere udsættes materialet på grund af 20 den høje temperatur for en stor belastning.It has long been known to sterilize material of the various kinds using superheated steam. Effective sterilization of packaging using superheated steam, whether the packaging is in the form of webs, e.g. of plastic foil or of 10 plastic laminated cardboard, or in the form of already finished containers, e.g. made of cardboard cutters, however, within the short sterilization time of an order of a few seconds needed for automatic tapping, can only be achieved by using temperatures in the range of from approx. 125 to 150 ° C. This implies that sterilization must be carried out at elevated pressures of the order of 2.4 to 5 bar. However, this significantly increases the cost of sterilization, since the sterilization system through which the packaging is to be passed must be made close to the surroundings and be designed for elevated pressure. Furthermore, due to the high temperature, the material is subjected to a large load.
For at sænke den til sterilisering nødvendige temperatur ved sterilisering med vanddamp er der derfor blevet foreslået en fremgangsmåde af den i indledningen nævnte type, ved hvilken fremgangsmåde vanddampen gøres sur (jvf. GB-PS 10 83 700). Også 25 ved denne kendte fremgangsmåde kan den damptemperatur, der er nødvendig for sterilisering ved en påvirkningstid på ca. 6 sekunder, imidlertid ikke presses under 118°C ved anvendelse af mættet damp, således at der også her må arbejdes med et vanddampovertryk på ca.Therefore, in order to lower the temperature needed for sterilization by sterilization with water vapor, a method of the type mentioned in the introduction has been proposed, in which process the water vapor is made acidic (cf. GB-PS 10 83 700). Also, in this known method, the vapor temperature required for sterilization at an operating time of approx. 6 seconds, however, is not pressed below 118 ° C using saturated steam, so that a water vapor overpressure of approx.
2 bar.2 bar.
30 Opfindelsens formål er derfor at tilvejebringe en fremgangsmåde af den i indledningen nævnte art, hvilken fremgangsmåde gør det muligt at opnå en upåklagelig sterilisering af emballage ved hjælp af mættet damp uden anvendelse af forhøjet tryk.The object of the invention is therefore to provide a method of the kind mentioned in the preamble, which makes it possible to achieve impeccable sterilization of packaging by means of saturated steam without the use of elevated pressure.
Dette formål opnås med fremgangsmåden ifølge opfindelsen, 35 hvilken fremgangsmåde er ejendommelig ved, at den emballageflade, der skal steriliseres, først tilføres syre, og at den med syre befugtede flade derefter behandles ved atmosfærisk tryk med strømmende damp.This object is achieved by the method according to the invention, which is characterized in that the packaging surface to be sterilized is first applied to acid and that the acid-wetted surface is then treated at atmospheric pressure with flowing steam.

Ved fremgangsmåden ifølge opfindelsen udnyttes følgelig både den steriliseringseffekt, der opnås med syre, såvel som den effekt, der opnås ved opvarmning med damp. Herved har det overraskende vist sig, at ved den forudgående tilførsel af syre svækkes kimene så 5 meget i deres resistens overfor den efterfølgende varmebehandling i damp og syre, der dels virker samtidig, dels efter hinanden, at der kan arbejdes med mættet damp ved normalt tryk.Accordingly, the method of the invention utilizes both the sterilizing effect obtained with acid as well as the effect obtained by heating with steam. As a result, it has surprisingly been found that in the prior application of acid, the germs are so much weakened in their resistance to the subsequent heat treatment in steam and acid that work partly simultaneously and partly that saturated steam can be worked under normal pressure. .
Syren påsprøjtes eller forstøves i findelt form på den emballageflade, der skal behandles, f.eks. en beholders indervæg, således 10 at der på denne flade dannes en tynd væskefilm. Det er imidlertid også muligt at dryppe eller hælde syren på fladen, således at der dannes et syrelag. Den samtidige anvendelse af begge forholdsregler er ligeledes tænkelig, f.eks. i det tilfælde, hvor syren forstøves ind i en stående beholder, således at sidevæggene herved befugtes, og 15 hvor der desuden dryppes syre ind i beholderen, således at der på den bund, der med sine hjørner og vinkler er særdeles problematisk hvad angår sterilisering, dannes et syrelag.The acid is sprayed or atomized in finely divided form on the packaging surface to be treated, e.g. the inner wall of a container so that a thin liquid film is formed on this surface. However, it is also possible to drip or pour the acid onto the surface so that an acid layer is formed. The simultaneous use of both measures is also conceivable, e.g. in the case where the acid is atomized into a standing container so that the sidewalls are wetted, and where further acid is dripped into the container, so that on the bottom which with its corners and angles is extremely problematic in terms of sterilization, an acid layer is formed.
For at den efterfølgende behandling med hed damp fungerer både til sterilisering og fjernelse af syren, er det hensigtsmæssigt at 20 anvende vanddampflygtige syrer, der let kan uddrives med vanddamp. Der kan med særlig fordel arbejdes med syre, der enten findes i det materiale, der senere skal fyldes i emballagematerialet, eller som er beslægtet med sådanne syrer. Ved fyldmaterialet mælk eller frugtsaft gælder dette f.eks. mælkesyre og lignende nærings-25 syrer. Herved undgås, at spormængder af den til sterilisering anvendte syre, der under omstændighederne forbliver på emballagematerialet, som et fremmed stof forringer påfyldningsmaterialet.In order for the subsequent treatment with hot steam to work both for sterilization and removal of the acid, it is convenient to use water vapor-volatile acids which can be easily expelled with water vapor. Acid can be used with particular advantage either in the material to be filled later in the packaging material or related to such acids. This applies to milk or fruit juices, for example. lactic acid and similar nutritional acids. This prevents trace amounts of the acid used for sterilization, which remains in the circumstances on the packaging material, as a foreign substance degrades the filling material.
Den virkning, der opnås med fremgangsmåden, kan yderligere forøges, enten ved at syren opvarmes før den tilføres til den flade, 30 der skal steriliseres, således at den i dampen iboende varme fører til en meget hurtig temperaturstigning af såvel syren som den flade, der skal behandles, eller ved, at selve fladen opvarmes, f.eks. ved hjælp af hed luft, før tilføring af syre.The effect obtained by the process can be further increased, either by heating the acid before it is applied to the surface to be sterilized, so that the heat inherent in the vapor leads to a very rapid rise in temperature of both the acid and the surface which must be treated or by heating the surface itself, e.g. using hot air, before applying acid.
Ifølge en yderligere udførelsesform for fremgangsmåden ifølge 35 opfindelsen kan opvarmningen af fladen med strømmende damp efterfølges af en behandling med strømmende hed luft.According to a further embodiment of the method according to the invention, the heating of the surface with flowing steam can be followed by a treatment with flowing hot air.
Fremgangsmåden ifølge opfindelsen kan frit anvendes overfor kontinuerligt gennemløbende, baneformet emballagemateriale, såvel som allerede fremstillede beholdere, f.eks. foldebeholdere fremstillet 3The process according to the invention can be used freely against continuous continuous web-shaped packaging material, as well as containers already made, e.g. folding containers made 3

• fra kartonudskæringer. J sidstnævnte tilfælde er den ovenfor omtalte kombinerede behandling hensigtsmæssig, ved hvilken behandling syren ved indsprøjtning eller forstøvning ved hjælp af dyser påføres væggene som en tynd film, samtidig med at der ved drypning ind pi 5 beholderbunden frembringes et tyndt syrelag, hvorved de i beholderen liggende hjørner og snitkanter rammes. Derefter indblæses den damp, der bringer såvel syrefilmen pi sidevæggene som syrelaget på beholderens bund til at fordampe, og som følge af varmeovergang fremkaldes en varmebehandling af vægge og bund.• from cardboard cutouts. In the latter case, the above-mentioned combined treatment is appropriate, in which treatment is applied to the acid by injection or spraying by means of the walls as a thin film, while producing a thin acid layer upon dripping into the container bottom, whereby the layers lying in the container corners and cut edges are affected. Thereafter, the vapor which evaporates both the acid film in the side walls and the acid layer on the bottom of the container is evaporated, and as a result of heat transfer a heat treatment of the walls and the bottom is induced.
10 Fremgangsmåden kan imidlertid også udføres således, at der kun frembringes det omtalte syrelag ved drypning ind på beholderbunden, hvorefter den indstrømmende, hede damp beriges med den fordampede syre, og ved dennes overstrygning af sidevæggene udvirkes en tilstrækkelig sterilisering. Ved denne fremgangsmåde er 15 det hensigtsmæssigt, at der ved hjælp af en passende anordning, f.eks. et neddykningsrør, sørges for, at den hede damp udblæses umiddelbar på det syrelag, der findes på beholderens bund, således at dampen beriges med syre og ved udstrømning af beholderen tvinges til at overstryge sidevæggene.However, the process can also be carried out such that only the said acid layer is produced by dripping onto the container bottom, after which the flowing hot steam is enriched with the evaporated acid, and by its over-spraying of the side walls sufficient sterilization is effected. In this method, it is convenient that by means of a suitable device, e.g. a dip tube, causes the hot steam to be blown out immediately on the acid layer present on the bottom of the container, so that the steam is enriched with acid and, upon discharge of the container, forced to overwrite the side walls.
20 Indsprøjtningen af syren kan ske ved hjælp af traditionelle forstøvningsdyser, der arbejder med trykluft eller med hed luft under tryk, og hvorigennem der frembringes en fin tåge og som følge heraf den omtalte ensartede befugtningsfilm på den flade, der skal steriliseres. Ved forstøvning med damp overtager forstøv-25 ningsmediet tillige en del af steriliseringsmetodens funktion. Syren foreligger herved delvist i dampform. Som syre har man navnlig opmærksomheden henledt på organiske syrer fra gruppen myresyre, eddikesyre, æblesyre, citronsyre, mælkesyre og ascorbinsyre. Dog er uorganiske syrer, f.eks. saltsyre, ikke udelukket.The injection of the acid can be done by conventional atomizing nozzles operating with compressed air or with hot air under pressure, thereby producing a fine mist and, as a result, the aforementioned uniform wetting film on the surface to be sterilized. When spraying with steam, the spraying medium also takes over part of the function of the sterilization method. The acid is hereby partially in vapor form. As an acid, particular attention has been paid to organic acids from the group formic acid, acetic acid, malic acid, citric acid, lactic acid and ascorbic acid. However, inorganic acids, e.g. hydrochloric acid, not excluded.
30 Opfindelsen belyses nu nærmere under henvisning til de skema tiske udførelseseksempler på den tilhørende tegning.The invention will now be further elucidated with reference to the schematic embodiments of the accompanying drawings.
Tegningen viser skematisk en transportlinie til emballagebeholdere i et påfyldningsanlæg, f.eks. til mælk. Påfyldningsanlægget vises ikke nærmere, da det med undtagelse af den efterfølgende 35 omtalte rækkefølge af tilføringsanordninger til syre henholdsvis hed damp og hed luft, kan være af en kendt type. Dette gælder også transportanlægget til fremføring af beholderne, hvilket f.eks. er en cellekæde, samt denne transportlinies anbringelse i en sterilluftszone, som det er sædvane ved aseptisk påfyldning.The drawing schematically shows a transport line for packaging containers in a filling plant, e.g. for milk. The filling system is not shown further, with the exception of the following mentioned order of supply devices for acid or hot steam and hot air, respectively, of a known type. This also applies to the transport facility for feeding the containers, which e.g. is a cell chain, as well as the placement of this transport line in a sterile air zone, as is customary for aseptic filling.

En beholder 1, der f.eks. kan være en foldet beholder af plast-lamineret karton, bevæges af et transportanlæg 2, f.eks. en cellekæde, trinvis fra venstre mod højre, således at beholderen indtager de pi tegningen viste positioner efter hinanden. Takttiden 5 beløber sig f.eks. til 1-2 sekunder. Kapaciteten af beholderen 1 er 1 liter.A container 1, e.g. may be a folded container of plastic-laminated cardboard, moved by a conveyor 2, e.g. a cell chain, stepwise from left to right, so that the container occupies the positions shown in the drawing one after the other. The clock time 5 amounts to e.g. for 1-2 seconds. The capacity of the container 1 is 1 liter.
I en foropvarmningsstation I indblæses hed luft med en temperatur pi ca. 200°C i det indre af den beholder 1, der befinder sig der. Herved foropvarmes beholderens inderflade til en temperatur på 10 fra ca. 50 til 70°C. I den efterfølgende syresprøjtestation II frembringes ved hjælp af en forstøvningsdyse 3, der arbejder med trykluft, en syretåge i det indre af beholderen, hvorved der frembringes et fint og vidtgående kontinuerligt nedslag på indervæggene og til sidst på beholderbunden, således at væggene og bunden bærer 15 en syrefilm. Som syre anvendes 90% mælkesyre; den indsprøjtede mængde beløber sig ved det angivne rumindhold af beholderen 1 til 0,5 ml.In a preheating station I, hot air is blown with a temperature of approx. 200 ° C in the interior of the container 1 located there. Hereby the inner surface of the container is preheated to a temperature of 10 from approx. 50 to 70 ° C. In the subsequent acid spraying station II, by means of a spray nozzle 3 working with compressed air, an acid mist is produced in the interior of the container, thereby producing a fine and continuous continuous impact on the inner walls and finally on the container bottom, so that the walls and the bottom support 15 an acid film. 90% lactic acid is used as an acid; the injected amount amounts to the specified volume of the container 1 to 0.5 ml.
Den tilknyttede steriliseringsstation III omfatter i eksemplet tre taktpositioner, i hvilke der gennem passende damptilførselsledninger 20 4 indblæses mættet damp ved atmosfærisk tryk, dvs. med en temperatur på maximalt 100°C. Herved opvarmes den syrefilm, der findes på beholdervæggene, såvel som selve beholdervægfladerne til den tilsvarende temperatur. Tilstedeværende kim dræbes, dels på grund af den varme syres indvirkning, dels på grund af den 25 efterfølgende dampbehandling. Ved valg af et bestemt antal stationer II og III på transportkæden, i givet fald et antal, der kan ændres, kan syrens og dampens påvirkningstid varieres.In the example, the associated sterilization station III comprises three clock positions in which, through appropriate vapor supply lines 20 4, saturated vapor is blown at atmospheric pressure, i.e. with a maximum temperature of 100 ° C. In this way, the acid film present on the container walls, as well as the container wall surfaces themselves, is heated to the corresponding temperature. The germs present are killed, partly because of the action of the hot acid, and partly because of the subsequent steam treatment. By selecting a certain number of stations II and III on the transport chain, where appropriate a number that can be changed, the operating time of the acid and the steam can be varied.
Steriliseringsstation III efterfølges af en efterbehandlingsstation IV, hvor der igen indblæses hed luft med en temperatur på 200°C 30 gennem passende dyser 5. Efterbehandlingsstationen IV omfatter i eksemplet to taktpositioner, således at alle rester af syre og vanddamp kan fjernes fra beholderens indre.Sterilization station III is followed by a post-treatment station IV, where again hot air at a temperature of 200 ° C is blown through suitable nozzles 5. In the example, the post-treatment station IV comprises two tact positions so that all residues of acid and water vapor can be removed from the interior of the container.
Ved en påfyldningsstation V fyldes beholderen 1 med fyldmateriale, f.eks. mælk; ved en forseglingsstation VI lukkes den øvre 35 ende af beholderen hermetisk.At a filling station V, the container 1 is filled with filling material, e.g. milk; at a sealing station VI, the upper end of the container is hermetically sealed.
Den dampmængde, der tilføres ved steriliseringsstationen III, er afmålt således, at den luft, der befinder sig i beholderen, i stor udstrækning fortrænges fuldstændig. Som følge af beholderen 11 s opholdstid i steriliseringsstationen III beløber dampens indvirknings 5The amount of steam supplied at the sterilization station III is metered so that the air contained in the container is largely completely displaced. As a result of the residence time of the container 11 in the sterilization station III, the action 5 of the steam amounts
DK 152348 BDK 152348 B
tid sig til ca. 6 sekunder. Alment tilrådes en indvirkningstid på fra 3 til 10 sekunder.time for approx. 6 seconds. Generally, an impact time of 3 to 10 seconds is recommended.
I efterbehandlingsstationen IV, hvor der blæses hed luft ind i beholderens indre, skal ethvert spor af syre- og dampkondensat 5 fjernes fra beholderens vægflader. Da der dog anvendes mælkesyre ved påfyldningsmaterialet mælk, altså en syre, der er forenelig med en del af påfyldningsmaterialet, er det uskadeligt, hvis der efter sterilisering i stationen III eventuelt forbliver ringe spor af mælkesyre i beholderens indre. Disse spor er for ringe til, at de 10 kan fremkalde en koagulering eller pH-ændring af mælken.In the post-treatment station IV, where hot air is blown into the interior of the container, any trace of acid and vapor condensate 5 must be removed from the wall surfaces of the container. However, since lactic acid is used in the filling material milk, that is, an acid which is compatible with part of the filling material, it is harmless if, after sterilization in the station III, little traces of lactic acid remain in the interior of the container. These traces are too small for them to induce a coagulation or pH change of the milk.
Som omtalt anvendes mælkesyren i en koncentration på 90%. Det gælder alment, at der skal anvendes si koncentreret syre som muligt, for at gøre forbehandlingstrinnet i stationen II virksom.As mentioned, the lactic acid is used at a concentration of 90%. It is generally important that as much concentrated acid as possible is used to make the pre-treatment step in station II work.
Uden at det er vist på udførelseseksemplet er det tænkeligt, at 15 beholderne ved hjælp af passende udformning af transportanordningen 2 føres således gennem stationerne II, fil og IV, at beholdernes åbne ende vender nedad. Herved vil eventuelle dråbeformige ansamlinger af syrekondensat under indvirkning af tyngdekraften løbe nedad og dryppe ud af beholderne. På denne mide kan også 20 ikke-vanddampflygtige syrer fjernes efter behandling, idet de skylles bort af dampkondensatet.Without being shown in the exemplary embodiment, it is conceivable that the containers, by appropriate design of the conveying device 2, are passed through the stations II, file and IV so that the open end of the containers faces downwards. In this way, any droplet accumulations of acid condensate under the influence of gravity will run downwards and drip out of the containers. In this mite, 20 non-vapor-volatile acids can also be removed after treatment, purging off the vapor condensate.
For at demonstrere effektiviteten af fremgangsmåden ifølge opfindelsen angives i den efterfølgende tabel resultatet af en forsøgsrække, hvor mælk påfyldtes aseptisk under forskellige betingelser i 25 en opstilling, der ligner opstillingen i det ovenfor beskrevne eksempel. Hver enkelt opstilling gennemførtes med ca. 500 pakker i 1-liters størrelse. Undersøgelse for sterilitet foretoges ved hjælp af pH-værdier efter en lagertid på 11 dage ved stuetemperatur.In order to demonstrate the effectiveness of the process of the invention, the following table sets forth the result of a test series in which milk was loaded aseptically under various conditions in a set similar to the arrangement of the example described above. Each set up was completed with approx. 500 packages in 1-liter size. Sterility testing was performed using pH values after a storage period of 11 days at room temperature.
I opstilling A, der tjente som nul-prøve, fyldtes mælk i 30 ubehandlede beholdere med det resultat, at 25% af beholderne var usterile. Hvis beholderne kun behandledes med hed luft (300°C, 8 sekunder), som i opstilling B, eller kun med damp (8 sekunder), som i opstilling C, så var 14 henholdsvis 7% usterile.In line A, which served as a zero sample, milk was filled into 30 untreated containers with the result that 25% of the containers were unsterile. If the containers were treated only with hot air (300 ° C, 8 seconds), as in position B, or only with steam (8 seconds), as in position C, then 14 and 7% were non-sterile, respectively.
I opstilling D behandledes beholderne med 0,3 ml syre og med 35 hed luft (300°C, 8 sekunder); herved kunne der ikke iagttages en dårlig virkning med myresyre, men med eddike- og mælkesyre.In position D, the vessels were treated with 0.3 ml of acid and with warm air (300 ° C, 8 seconds); hereby a poor effect could not be observed with formic acid, but with acetic and lactic acid.
Ved opstilling E, der svarer til fremgangsmåden ifølge opfindelsen, skete der en behandling af beholderne med syre og damp (0,3 henholdsvis 1 ml syre plus 8 sekunders damppivirkning), 6At set E, corresponding to the process according to the invention, the containers were treated with acid and vapor (0.3 and 1 ml of acid plus 8 seconds of steam action, respectively), 6

hvorved der indsprøjtes 0,3 ml syre (E^, Eg, Eg) eller pådryppedes 1 ml syre (E2, E^, Eg). Herved opnåedes tydelig en steriliseringseffekt; i 4 ud af 6 tilfælde opnåedes en særdeles god sterilitets rate. Fordelen med fremgangsmåden ifølge opfindelsen er åbenlys.whereby 0.3 ml of acid (E 2, Eg, Eg) is injected or 1 ml of acid (E 2, E 2, Eg) is added. Thereby a sterilizing effect was clearly achieved; in 4 out of 6 cases a very good rate of sterility was obtained. The advantage of the method according to the invention is obvious.
