Description
Die vorliegende Erfindung betrifft ein Herstellverfahren für einen Mehrschichtenverbund, bei dem zuerst eine oder mehrere Schichten auf einem Trägermaterial durch Beschichten mit einer flüssigen Komponente aufgebracht werden, danach der beschichtete Mehrschichtenverbund getrocknet wird und danach der getrocknete Mehrschichtenverbund aufgerollt wird. Der letzte Arbeitsschritt im Verfahren ist das Reinigen der Anlage, das erfindungsgemäß mittels eines CIP-Systems durchgeführt wird, d.h. eines in die Anlage integrierten Systems, das ein "Cleaning-In-Place" ermöglicht.
Ein derartiges Verfahren ist aus der
- ein Gehäuse, das mindestens einen Behandlungsabschnitt für die Substratbahn, einen Zufluss und einen Abfluss für ein Medium umfasst,
- wobei im Behandlungsabschnitt mindestens eine Leitwalze zum Transport der Substratbahn angeordnet ist,
- wobei zur Beaufschlagung der Substratbahn mit Medium mindestens eine Düsenvorrichtung vorgesehen ist, durch welche das Medium in den Behandlungsabschnitt geleitet werden kann. Dabei ist mindestens eine Leitwalze mit mindestens einer Reinigungsdüse ausgerüstet, durch welche zu Reinigungszwecken flüssige und/oder gasförmige Reinigungssubstanzen in den Behandlungsabschnitt geleitet werden können,
- wobei der Innenraum jeder Behandlungsabschnitt/ jede Trockenzone zur kontrollierten Reinigung mit Sprühdüsen zum Versprühen einer Reinigungsflüssigkeit ausgestaltet ist,
- und wobei der Innenraum des Trockenofens totraumfrei ausgeführt ist,
- wobei alle für die Ablagerung von eventuellen Verunreinigungen in Frage kommenden Ecken und Nischen entweder durch entsprechende technische Konstruktionen ausgeschlossen werden oder durch geeignete Abdeckelemente vor dem Eindringen von Verunreinigungen abgeschirmt sind,
- wobei alle Transportwalzen, mit denen der beschichtete Mehrschichtverbund durch den Trockenofen und die einzelnen Behandlungsabschnitte / Trockenzonen hindurch bewegt wird, als Hohlwellen ausgestaltet und mit Sprühdüsen ausgerüstet sind,
- und wobei die Reinigungsflüssigkeit in dem nach unten konisch zulaufend ausgestalteten unteren Gehäuseteil des Trockenofens zusammenfließt und dort über einen Ablauf abgelassen wird.
Bei dem Schritt des Beschichtens werden eine oder mehrere flüssige Komponenten mittels einer Beschichtungsanlage auf ein Trägermaterial aufgebracht. Der danach fertig beschichtete Mehrschichtenverbund enthält aber noch einen relativ hohen Anteil an Flüssigkeit, die normalerweise im nächstfolgenden Herstellschritt durch Hitze entfernt wird.
Der fertig beschichtete Mehrschichtenverbund wird daher zum Trocknen einem Trockenofen zugeführt, der vorzugsweise in kontinuierlicher Fahrweise betrieben wird. Der Trockenofen kann eine oder mehrere Trockenzonen umfassen. Die einzelnen Trockenzonen unterscheiden sich dabei durch ihre jeweils unterschiedlichen Temperaturen und Luftmengen. Daneben soll jede Trockenzone ihre eigene Luftregelung besitzen, in die üblicherweise auch noch Filter- und Heizelemente integriert sind. Durch die Einwirkung der Wärme im Trockenofen auf den beschichteten Mehrschichtverbund gelangt die Feuchtigkeit aus dem beschichteten Mehrschichtverbund in den Luftstrom. Um die Feuchtigkeit im Luftkreislauf stabil zu halten, muss trockene Frischluft zugeführt werden, mit der die verbrauchte feuchte Luft ersetzt wird. Schwankungen der Feuchtigkeit in der Frischluftzufuhr wirken sich unmittelbar aus auf die Effizienz der Trocknung und mittelbar auf die Qualitätseigenschaften des fertigen Produkts, das nicht zu feucht, aber auch nicht zu trocken sein soll.The present invention relates to a production method for a multi-layer composite, in which first one or more layers are applied to a carrier material by coating with a liquid component, after which the coated multilayer composite is dried and then the dried multilayer composite is rolled up. The last step in the process is the cleaning of the plant, which is carried out according to the invention by means of a CIP system, ie an integrated system in the system, which enables a "cleaning-in-place".
Such a method is known from
- a housing comprising at least a treatment section for the substrate web, an inflow and outflow for a medium,
- wherein in the treatment section at least one guide roller for transporting the substrate web is arranged,
- wherein for applying the substrate web with medium at least one nozzle device is provided, through which the medium can be passed into the treatment section. In this case, at least one guide roller is equipped with at least one cleaning nozzle, through which cleaning and / or gaseous cleaning substances can be conducted into the treatment section for cleaning purposes,
- wherein the interior space of each treatment section / drying zone is designed for controlled cleaning with spray nozzles for spraying a cleaning liquid,
- and wherein the interior of the drying oven is executed dead space free,
- all the corners and niches which may be considered for the deposition of any impurities, either by appropriate technical Structures are excluded or shielded by suitable cover elements from the ingress of contaminants,
- wherein all transport rollers with which the coated multi-layer composite is moved through the drying oven and the individual treatment sections / drying zones are designed as hollow shafts and equipped with spray nozzles,
- and wherein the cleaning liquid flows together in the downward conically designed lower housing part of the drying oven and is discharged there via an outlet.
In the coating step, one or more liquid components are applied to a substrate by means of a coater. However, the subsequently coated multilayer composite still contains a relatively high proportion of liquid, which is normally removed by heat in the next production step.
The finished coated multi-layer composite is therefore supplied for drying a drying oven, which is preferably operated in a continuous mode. The drying oven may comprise one or more drying zones. The individual drying zones differ in their different temperatures and air volumes. In addition, each drying zone should have its own air control, in which usually also filter and heating elements are integrated. Due to the action of heat in the Drying oven on the coated multi-layer composite passes the moisture from the coated multi-layer composite in the air flow. In order to keep the humidity in the air circulation stable, dry fresh air must be supplied, with which the used moist air is replaced. Fluctuations in the humidity in the fresh air supply have an immediate effect on the efficiency of the drying and indirectly on the quality characteristics of the finished product, which should not be too moist, but also not too dry.
Der aus dem Trockenofen austretende getrocknete Mehrschichtenverbund wird sofort auf Rollen aufgewickelt.The dried multilayer composite emerging from the drying oven is immediately wound on rolls.
Während der fertig getrocknete und aufgerollte Mehrschichtverbund wahlweise zwischengelagert oder abtransportiert wird, steht im Betrieb die vollständige Reinigung der Anlage an, die möglichst rasch, aber zugleich auch so gründlich durchgeführt werde soll, dass eine "Crosscontamination", d.h. eine Übertragung von Spuren von Inhaltsstoffen des im vorherigen Produktionsdurchlauf in der Anlage produzierten Materials auf das in der Anlage im nachfolgenden Produktionsdurchlauf produzierte Material, mit Sicherheit ausgeschlossen wird. Diese besonders gründliche Reinigungsmethode wird in der Fachsprache auch als GMP-gerecht bezeichnet (siehe dazu Wikipedia, freie Enzyklopädie im Internet). In Kombination damit soll die besonders unwirtschaftliche Stillstandszeit der Anlage auf eine möglichst kurze Zeitdauer verkürzt werden.While the ready-dried and rolled-up multi-layer composite is either temporarily stored or transported away, in the operation of the complete cleaning of the plant is to be performed as quickly as possible but at the same time so thoroughly that a "Cross Contamination", i. a transfer of traces of ingredients of the material produced in the previous production run in the plant to the material produced in the plant in the subsequent production run, is excluded with certainty. This particularly thorough cleaning method is referred to in the jargon as GMP-fair (see Wikipedia, free encyclopedia on the Internet). In combination, the particularly uneconomic downtime of the system should be shortened to a shortest possible duration.
Aufgabe der vorliegenden Erfindung war es daher, ein einfaches, gleichzeitig aber auch garantiert sicheres Reinigungsverfahren für den Trockenofen in der Beschichtungsanlage anzugeben, das unter wirtschaftlichen Bedingungen großtechnisch durchgeführt werden kann. Gleichzeitig soll damit die Trocknung des beschichteten Mehrschichtverbundes optimal auf die Anforderungen transdermaler Applikationssysteme oder Wafer einzustellen sein, dazu gehört, dass der Trockenofen mehrere Trockenzonen mit kontrollierter Luftführung besitzt, wobei in den einzelnen Trockenzonen eine präzise und individuelle Regelung der Luftfeuchtigkeit jederzeit gewährleistet sein muss.Object of the present invention was therefore to provide a simple, but also guaranteed safe cleaning process for the drying oven in the coating plant, which can be carried out on an industrial scale under economic conditions. At the same time the drying of the coated multi-layer composite should be optimally adjusted to the requirements of transdermal application systems or wafers, including that the drying oven has several drying zones with controlled air flow, in the individual drying zones a precise and individual control of humidity must be ensured at all times.
Gelöst wird diese Aufgabe durch ein Verfahren der eingangs genannten Gattung, dessen Kennzeichenmerkmale darin zu sehen sind, dass während der Trocknung des beschichteten Mehrschichtenverbundes im Trockenofen mit mindestens zwei Trockenzonen der Luftkreislauf jeder Trockenzone vollständig auf Frischluftzufuhr eingestellt wird und jede individuelle Trockenzone über eine unabhängig von allen anderen Trockenzonen regulierbare Konditionierung des zugeführten Frischluftstromes verfügt, wobei die durch eine Luftzufuhr eintretende Luft über ein kombiniertes Heiz-Düsen-System auf den zu trocknenden Mehrschichtenverbund appliziert wird.This object is achieved by a method of the type mentioned, whose characteristics are to be seen in that during the Drying of the coated multi-layer composite in a drying oven with at least two drying zones of the air cycle of each drying zone is completely adjusted to fresh air supply and each individual drying zone via an independent of all other drying zones regulatable conditioning of the supplied fresh air flow, wherein the air entering through an air supply via a combined heating nozzles -System is applied to the multi-layer composite to be dried.
Als Trägermaterial für den Mehrschichtenverbund eignen sich bahnförmige Materialien wie Papierbahnen oder Textilbahnen in Form von Geweben oder Vliesen aus natürlichen oder künstlichen Fasern, es können aber auch Folien aus Kunststoff eingesetzt werden, die ggf. mit Löchern versehen sein können.As a carrier material for the multilayer composite are web-like materials such as paper webs or textile webs in the form of woven or nonwoven fabrics of natural or artificial fibers, but it can also be used plastic films, which may optionally be provided with holes.
Als flüssige Komponente für die Beschichtung des Trägermaterials kommen für das erfindungsgemäße Verfahren im wesentlichen organische Rohstoffe in Mischung mit Wasser und/oder organischen Lösemitteln in Frage. Auch Mischungen organischer Rohstoffe, die wasserlöslich oder in Wasser suspendierbar sind, eignen sich bestens. Beispiele solcher organischer Rohstoffe sind Polymere wie Polyvinylalkohol, Polyvinylpyrrolidon, Cellulosederivate, Polyvinylacetat, Polyethylenglykol, Alginate, Xanthate, Gelatine und andere mehr oder weniger wasserlösliche Polymere, die der Fachmann kennt. Falls gewünscht, können die flüssigen Komponenten noch weitere Füllstoffe enthalten wie Mannitol, Lactose, Kalziumphosphate, Glucose oder Sorbinsäurederivate. Ferner eigenen sich Zusätze von aktiven Substanzen wie Arzneimittel, Aromastoffe, Menthol, Glutamat und andere Zusatzstoffe, teilweise auch flüchtiger Art.Suitable liquid components for the coating of the support material for the process according to the invention are essentially organic raw materials mixed with water and / or organic solvents. Even mixtures of organic raw materials that are water-soluble or suspendable in water, are ideal. Examples of such organic raw materials are polymers such as polyvinyl alcohol, polyvinylpyrrolidone, cellulose derivatives, polyvinyl acetate, polyethylene glycol, alginates, xanthates, gelatin and other more or less water-soluble polymers known to those skilled in the art. If desired, the liquid components may contain other fillers such as mannitol, lactose, calcium phosphates, glucose or sorbic acid derivatives. Furthermore, additions of active substances are appropriate Substances such as medicines, flavors, menthol, glutamate and other additives, sometimes volatile.
Das Beschichten des Trägermaterials mit einer oder mit mehreren flüssigen Komponenten erfolgt erfindungsgemäß nach üblichen Auftragstechniken. Die flüssigen Komponenten können auf das Trägermaterial z. B. aufgegossen, mit Hilfe von Walzen oder mit anderen, dem Fachmann einschlägig bekannten Verfahren aufgetragen werden.The coating of the carrier material with one or more liquid components is carried out according to the invention by conventional application techniques. The liquid components can be applied to the substrate z. B. poured, with the help of rollers or with other, the expert known in the art processes are applied.
Für das Reinigen der Beschichtungsanlage werden alle mit dem Trägermaterial und/oder mit der oder den flüssigen Komponenten in Berührung kommenden Anlagenteile mit einer CIP (= Cleaning-In-Place)-Technik gründlich gereinigt. Ferner besteht Reinigungsbedarf für die restlichen Anlagenteile insbesondere dann, wenn sich das Beschichtungsgut während des Beschichtungsvorganges auch nur im geringsten Maße vom Trägermaterial gelöst hat und/oder Inhaltsstoffe des Beschichtungsgutes beim Beschichtungsvorgang verdampfen und sich in der Beschichtungsanlage niederschlagen.For cleaning the coating system, all parts of the system which come into contact with the carrier material and / or with the liquid component (s) are thoroughly cleaned with a CIP (= Cleaning-In-Place) technique. Furthermore, there is a need for cleaning the remaining parts of the system, in particular when the coating material has dissolved even during the coating process even the slightest extent from the carrier material and / or evaporate the ingredients of the coating material during the coating process and precipitate in the coating system.
Der Trockenofen, der für das erfindungsgemäße Verfahren eingesetzt wird, besitzt vorzugsweise mindestens zwei, besonders bevorzugt bis zu vierzehn Trockenzonen, in denen der Luftkreislauf vollständig auf Frischluftzufuhr eingestellt ist. Die Zuluftdüsen sind dabei so ausgestaltet, dass sie in jeder Trockenzone eine gleichmäßige Belüftung der gesamten Oberfläche des in der jeweiligen Trockenzone befindlichen beschichteten Mehrschichtverbundes mit dem konditionierten Frischluftstrom ermöglichen. Dabei verfügt jede individuelle Trockenzone in dem Trockenofen über eine unabhängig von allen anderen Trockenzonen regulierbare Konditionierung des zugeführten Frischluftstromes. So ist gewährleistet, dass in jeder Trockenzone die optimalen Trockenbedingungen über die Luftmenge, die Lufttemperatur und die Luftfeuchtigkeit genau eingestellt werden können.The drying oven used for the process according to the invention preferably has at least two, more preferably up to fourteen, drying zones in which the air circuit is completely set to fresh air supply. The supply air nozzles are designed so that they allow uniform ventilation of the entire surface of the present in the respective drying zone coated multi-layer composite with the conditioned fresh air flow in each drying zone. Each individual drying zone in the drying oven has a conditioning of the supplied fresh air flow which can be regulated independently of all other drying zones. This ensures that the optimum drying conditions can be precisely set in each drying zone via the air volume, the air temperature and the humidity.
Der Trockenofen, der für das erfindungsgemäße Verfahren eingesetzt wird, ist vorzugsweise so konstruiert, dass sein gesamter Innenraum kontrolliert reinigbar und leicht zugänglich ist. Das bedeutet insbesondere, dass alle Bauteile des Trockenofens, die mit dem darin produzierten Produkt in Berührung kommen können, zum Zweck der Reinigung nicht ausgebaut werden müssen, sondern mit Hilfe des in den Trockenofen integrierten Systems in CIP-Technik gereinigt werden können. Das äußere Gehäuse des Trockenofens ist dabei so ausgestaltet, dass der obere Teil des Trockenofens nach oben abgehoben werden kann, um so die einfache Zugänglichkeit für den oberen und unteren Teil des Trockenofens zu gewährleisten. Das dient dazu, den Reinigungserfolg der CIP-Technik zu kontrollieren. Alle Einbauteile im Innern des Trockenofens sind so ausgestaltet, dass eine Demontage zu Reinigungszwecken nicht notwendig ist. Darüber hinaus ist der Innenraum des Trockenofens totraumfrei ausgeführt. Das bedeutet, dass alle für die Ablagerung von eventuellen Verunreinigungen in Frage kommenden Ecken und Nischen durch entsprechende technische Konstruktion nicht auftreten oder, wenn doch, dann durch geeignete Abdeckelemente vor dem Eindringen von Verunreinigungen abgeschirmt sind.The drying oven used for the process according to the invention is preferably designed so that its entire interior can be cleaned in a controlled manner and easily accessible. This means in particular that all components of the drying oven, which can come into contact with the product produced therein, need not be removed for the purpose of cleaning, but can be cleaned with the help of integrated in the drying oven system in CIP technology. The outer housing of the drying oven is designed so that the upper part of the drying oven can be lifted upwards, so as to ensure easy accessibility for the upper and lower part of the drying oven. This serves to control the cleaning success of the CIP technique. All built-in parts inside the drying oven are designed in such a way that disassembly for cleaning purposes is not necessary. In addition, the interior of the drying oven is executed dead space free. This means that all corners and niches that may be considered for the deposition of possible impurities do not occur through appropriate technical construction or, if so, are then shielded from the ingress of contaminants by suitable cover elements.
Alle Transportwalzen, mit denen der beschichtete Mehrschichtverbund durch den Trockenofen und die verschiedenen Trockenzonen hindurch bewegt wird, sind vorzugsweise als Hohlwellen ausgestaltet und mit Sprühdüsen ausgerüstet. Wenn sie an eine Hochdruckpumpe angeschlossen sind, ermöglicht das eine sehr schnelle Reinigung dieser Transportwalzen von innen heraus sowie gleichzeitig auch die Reinigung ihrer unmittelbaren Umgebung innerhalb des Trockenofens, ohne dass dazu ein Ausbau dieser Teile des Trockenofens notwendig wird. Die Sprühdüsen sind erfindungsgemäß so angeordnet, dass alle Bereiche des Innenraums des Trockenofens mittels der CIP-Technik erreicht werden und so kontrolliert reinigbar sind. Die Transportwalzen drehen sich vorzugsweise während des Reinigungsprozesses langsam, was die Reinigungswirkung im gesamten Innenraum des Trockenofens optimiert. Die für die Reinigung benötigte Reinigungsflüssigkeit sammelt sich in dem nach unten konisch ausgebildeten Boden des Trockenofens und kann dort entweder der Hochdruckpumpe wieder zugeführt oder einfach abgelassen oder mit Hilfe einer Pumpe entfernt werden. Somit kann ein Reinigungsverfahren eindeutig charakterisiert und validiert werden.All transport rollers with which the coated multi-layer composite is moved through the drying oven and the various drying zones are preferably designed as hollow shafts and equipped with spray nozzles. When connected to a high-pressure pump, this enables very fast cleaning of these transport rollers from the inside as well as the cleaning of their immediate environment within the drying oven, without the need to dismantle these parts of the drying oven. The spray nozzles are arranged according to the invention so that all areas of the interior of the drying oven are achieved by means of the CIP technique and are controlled so cleanable. The transport rollers preferably rotate slowly during the cleaning process, which optimizes the cleaning effect in the entire interior of the drying oven. The cleaning fluid needed for the cleaning collects in the downwardly conical bottom of the drying oven and can either be fed back to the high pressure pump or simply drained or removed by means of a pump. Thus, a purification process can be uniquely characterized and validated.
Der nach dem erfindungsgemäßen Verfahren hergestellte Mehrschichtenverbund eignet sich insbesondere zur Verwendung als transdermales System zur Applikation von Arzneimitteln oder Kosmetika oder für die Applikation in Körperhöhlen.The multilayer composite produced by the process according to the invention is particularly suitable for use as a transdermal system for the application of medicaments or cosmetics or for application in body cavities.
