Abstract
Description
Die Erfindung bezieht sich auf ein Verfahren und eine Vorrichtung zum Reinigen von Tablettier-, Dragier- und Granuliermaschinen, insbesondere von Rundlauf-Tablettenpressen mit einer mindestens den Rotor einschliessenden Behandlungskammer.The invention relates to a method and a device for cleaning tabletting, coating and granulating machines, in particular rotary tablet presses, with a treatment chamber which includes at least the rotor.
Aus "Pharmaceutical Cosmetic Equipment", Heft Jan./Feb. 1988 ist eine Rundlauf-Tablettenpresse vorbekannt, die mit einer mindestens den Rotor einschliessenden Behandlungskammer versehen ist, die mit einer Reinigungsflüssigkeit geflutet wird und bei der mittels Ultraschall die Schmutzpartikel des Rotors abgestoßen werden. Die mit den Schmutzpartikeln behaftete Flüssigkeit wird nach einer vorgegebenen Behandlungszeit wieder abgesaugt. Nachteilig hierbei ist, daß die leichten Schmutzpartikel auf der Oberfläche der Flüssigkeit schwimmen und beim Absaugen der Flüssigkeit auf den Oberflächen des Rotors und der Behandlungskammer einen Schmutzfilm hinterlassen, der auch nach mehrfachem Fluten der Behandlungskammer nicht vollständig beseitigt werden kann. Nachteilig ist ferner das nachträglich erfolgende Trocknen der innerhalb der Behandlungskammer befindlichen Rotor-Bauteile, insbesondere werden Flüssigkeitsreste aus Bohrungen und Trennfugen des Rotors nicht vollständig entfernt.From "Pharmaceutical Cosmetic Equipment", Issue Jan./Feb. In 1988 a rotary tablet press was previously known, which was provided with a treatment chamber enclosing at least the rotor, which was flooded with a cleaning liquid and in which the dirt particles of the rotor were repelled by means of ultrasound. The liquid with the dirt particles is sucked off again after a predetermined treatment time. The disadvantage here is that the light dirt particles float on the surface of the liquid and leave a dirt film on the surfaces of the rotor and the treatment chamber when the liquid is sucked off repeated flooding of the treatment chamber cannot be completely eliminated. Another disadvantage is the subsequent drying of the rotor components located in the treatment chamber, in particular liquid residues are not completely removed from bores and joints of the rotor.
Der Erfindung liegt von daher die Aufgabe zugrunde, ein Verfahren und eine Vorrichtung zum Reinigen von Tablettier-, Dragier- und Granuliermaschinen, insbesondere einer Rundlauf-Tablettenpresse zu schaffen, wobei unter geringem Einsatz von Reinigungsflüssigkeiten eine vollständige Entfernung der Flüssigkeitsreste aus der Behandlungskammer und von den in diesem Bauteilen, insbesondere einer Rundlauf-Tablettenpresse, sichergestellt ist.The invention is therefore based on the object of providing a method and a device for cleaning tableting, coating and granulating machines, in particular a rotary tablet press, with complete removal of the liquid residues from and from the treatment chamber with little use of cleaning liquids in this component, in particular a rotary tablet press, is ensured.
Zur Lösung dieser Aufgabe sieht das erfindungsgemäße Verfahren vor, daß innerhalb der Behandlungskammer nacheinander ein Reinigungs- und ein Spülmittel versprüht und wieder abgesaugt werden, daß danach alle Öffnungen der Behandlungskammer verschlossen werden und ein Unterdruck, insbesondere von etwa 0,1 bis 0,2 bar, innerhalb der dann gekapselten Behandlungskammer erzeugt wird. Die erfindungsgemäße Vorrichtung sieht vor, daß Sprühköpfe zum Versprühen des Reinigungs- und Spülmittels innerhalb der Behandlungskammer vorgesehen und Anschlüsse zum Absaugen des Reinigungs- und Spülmittels vorgesehen sind und daß Einrichtungen zum Verschließen aller Öffnungen der Behandlungskammer und eine an diese anschließbare Unterdruckeinrichtung vorgesehen sind, um den Unterdruck von etwa 0,1 bis 0,2 bar vom Absolutdruck innerhalb der dann gekapselten Behandlungskammer zu erzeugen. Das erfindungsgemäße Verfahren und die erfindungsgemäße Vorrichtung ermöglichen ein Reinigen, insbesondere der in der Behandlungskammer befindlichen Bauteile des Rotors einer Rundlauf-Tablettenpresse, mit geringem Einsatz an Reinigungs- und Spülmitteln und ein vollständiges Entfernen der eingesetzten Reinigungs- und Spülmittel durch die Anwendung des Unterdruckes von etwa 0,1 bis 0,2 bar vom Absolutdruck innerhalb der gekapselten Behandlungskammer. Die Erzeugung des Vakuums innerhalb der Behandlungskammer ermöglicht ein Trocknen der innerhalb der Behandlungskammer befindlichen Bauteile der Rundlauf-Tablettenpresse selbst in unzugänglichen Öffnungen und Trennfugen des Rotors. Dabei werden noch verbliebene Flüssigkeitsreste mittels des Unterdruckes abgesaugt und über den Unterdruckanschluß abgezogen.To achieve this object, the method according to the invention provides that a cleaning agent and a rinsing agent are sprayed and sucked off again one after the other within the treatment chamber, then all openings of the treatment chamber are closed and a vacuum, in particular from about 0.1 to 0.2 bar , is generated within the encapsulated treatment chamber. The device according to the invention provides that spray heads for spraying the cleaning and rinsing agent are provided within the treatment chamber and connections are provided for suctioning off the cleaning and rinsing agent and that devices for closing all openings of the treatment chamber and a vacuum device which can be connected to them are provided in order to prevent the Negative pressure of about 0.1 to 0.2 bar from the absolute pressure within the encapsulated treatment chamber. The method and the device according to the invention enable cleaning, in particular the components of the rotor of a rotary tablet press located in the treatment chamber, with little use of detergents and dishwashing agents and complete removal of the detergents and dishwashing agents used by applying the negative pressure of approximately 0.1 to 0.2 bar of the absolute pressure within the encapsulated treatment chamber. The generation of the vacuum within the treatment chamber enables the components of the rotary tablet press located within the treatment chamber to dry, even in inaccessible openings and parting lines of the rotor. Remaining liquid residues are sucked off by means of the vacuum and drawn off via the vacuum connection.
Weitere vorteilhafte Ausgestaltungen der Erfindung ergeben sich aus den Unteransprüchen. Besonders vorteilhaft ist es, wenn die Reinigungs- und Spülvorgänge bei einer über der Raumtemperatur liegenden Temperatur, vorzugsweise zwischen 40 und 70 °C, durchgeführt werden. Dabei wird der Rotor vorzugsweise mit kleinen Drehzahlen gedreht. Schließlich kann vor dem Aufbringen des Unterdruckes eine Heißdampfbehandlung des Rotors innerhalb der Behandlungskammer erfolgen, wobei über einen bestimmten Zeitraum Sterilisationsbedingungen eingestellt werden.Further advantageous embodiments of the invention result from the subclaims. It is particularly advantageous if the cleaning and rinsing processes are carried out at a temperature above room temperature, preferably between 40 and 70 ° C. The rotor is preferably rotated at low speeds. Finally, before applying the negative pressure, the rotor can be subjected to superheated steam treatment within the treatment chamber, sterilization conditions being set over a certain period of time.
Das erfindungsgemäße Verfahren wird anschließend anhand der in der Zeichnung dargestellten erfindungsgemäßen Vorrichtung näher erläutert. Die einzige Figur zeigt eine Seitenansicht einer Rundlauf-Tablettenpresse mit innerhalb der Behandlungskammer befindlichem Rotor, wobei bestimmte Bauteile vorher ausgebaut sind.The method according to the invention is then followed explained in more detail with reference to the device according to the invention shown in the drawing. The single figure shows a side view of a rotary tablet press with a rotor located within the treatment chamber, certain components having been removed beforehand.
