Description

MISCHTROCKNER AUFWEISEND EINEN KUGELFÖRMIGEN MISCHBEHÄLTERMIXING DRYER PROVIDING A BALL MIXING CONTAINER
Die vorliegende Erfindung betrifft einen Mischtrockner gemäss Oberbegriff des Anspruchs 1.The present invention relates to a mixing dryer according to the preamble of claim 1.
Derartige Mischtrockner finden ihre Verwendung bei der Herstellung von pharmazeutischen oder chemischen Produkten, wie Arzneimittel oder Nahrungsmittel. Mischtrockner sind dem Fachmann hinlänglich bekannt und beispielsweise in der EP-1'118'381 beschrieben. Diese Vorrichtungen weisen einen Behälter auf, welcher die Form eines Rotationskörpers hat und aus zwei voneinander lösbaren Halbschalen besteht, welche eine im Wesentlichen horizontal liegende Trennebene aufweisen. Die obere Halbschale ragt durch die Decke des Produktionsraumes, um die motorischen Einheiten für das Rührwerk oder den Zerhacker oberhalb des Produktionsraumes anordnen und von diesem räumlich trennen zu können. Die Entnahme des bearbeiteten Füllgutes wird über einen Gut-Auslass in der unteren Halbschale ermöglicht. Für die Reinigung der unteren Halbschale kann diese über ein Gelenk nach unten verschwenkt werden oder mit Hilfe einer Hub- und Senkvorrichtung vertikal nach unten verschoben und horizontal verschwenkt werden. Um den Gut-Auslass am tiefsten Punkt des Behälters anordnen zu können, ist die Welle des Rührwerks gegenüber der Vertikalen um ca. 20° geneigt.Such mixers are used in the manufacture of pharmaceutical or chemical products, such as pharmaceuticals or foods. Mixing dryers are well known to the skilled person and described for example in EP-1'118'381. These devices have a container, which has the shape of a body of revolution and consists of two detachable half-shells, which have a substantially horizontal plane of separation. The upper half-shell protrudes through the ceiling of the production room in order to arrange the motor units for the agitator or the chopper above the production room and to be able to separate from this spatially. The removal of the processed filling material is made possible via a good outlet in the lower half-shell. For the cleaning of the lower half-shell it can be pivoted downwards via a joint or moved vertically downwards by means of a lifting and lowering device and pivoted horizontally. In order to arrange the good outlet at the lowest point of the container, the shaft of the agitator is inclined relative to the vertical by about 20 °.
Leider erweist sich bei dieser Anordnung das Reinigen der oberen Halbschale als aufwendig resp. kann diese nicht an allen Stellen sorgfältig gereinigt werden, weil beim öffnen des Behälters immer das eine oder andere Rührorgan des Rührwerks in die obere Halbschale ragt.Unfortunately, in this arrangement, the cleaning of the upper half-shell proves to be expensive resp. This can not be carefully cleaned at all points, because when opening the container always one or the other agitator of the agitator protrudes into the upper half-shell.
Es ist deshalb Aufgabe der vorliegenden Erfindung, einen Mischtrockner zu schaffen, bei welchem der Gut-Auslass im untersten Bereich des Behälters angeordnet ist und bei welchem eine vollständige Reinigung der Innenseiten in einfacher Weise möglich ist.It is therefore an object of the present invention to provide a mixing dryer, wherein the good outlet is located in the lowermost region of the container and in which a complete cleaning of the insides is possible in a simple manner.
Diese Aufgabe wird erfindungsgemäss durch einen Mischtrockner in Form eines Kugelmischers mit den Merkmalen des Anspruchs 1 gelöst und insbesondere durch einen Mischtrockner, bei welchem die Rührwerkachse zur Vertikalen geneigt ist und bei welchem die Trennebene zwischen den beiden Behälterschalen senkrecht zur Rührwerkachse angeordnet ist und wobei die Rührorgane die untere Behälterschale nicht überragen.This object is achieved according to the invention by a mixing dryer in the form of a ball mixer with the features of claim 1 and in particular by a mixing dryer in which the agitator axis is inclined to the vertical and in which the parting plane between the two Container shells is arranged perpendicular to the agitator axis and wherein the stirring members do not project beyond the lower container shell.
Weitere bevorzugte Ausführungsformen weisen die Merkmale der abhängigen Ansprüche auf.Further preferred embodiments have the features of the dependent claims.
Vorteilhafterweise ist die Rührwerkachse um 14°-18°, insbesondere 16° zur Vertikalen geneigt und sind die beiden Behälterschalen mit Hilfe eines Scharniergelenks gegeneinander verschwenkbar. Dabei erweist es sich als besonders vorteilhaft, dass das Scharniergelenk in oder oberhalb derAdvantageously, the agitator axis is inclined by 14 ° -18 °, in particular 16 ° to the vertical and the two container shells with the aid of a hinge joint against each other. It proves to be particularly advantageous that the hinge joint in or above the
Trennebene und unterhalb der Äquatorebene angeordnet ist. Darüber hinaus sind die Mischorgane in einer bevorzugten Ausführungsform mit Förderkanälen versehen, in welchen ein heisses Fluid, z.B. Wasserdampf, zirkulieren kann, um dieselben beheizen zu können.Dividing plane and is arranged below the equatorial plane. Moreover, in a preferred embodiment, the mixing elements are provided with delivery channels in which a hot fluid, e.g. Water vapor, can circulate to heat the same.
Die Vorteile des erfindungsgemässen Mischtrockners sind dem Fachmann unmittelbar ersichtlich. Einerseits führt die geneigte Anordnung des Rührwerks zu einer besseren Durchmischung und andererseits erlaubt die vollständige Freilegung der oberen Behälterschale beim öffnen des Behälters eine einwandfreie Reinigung derselben. Insbesondere ermöglicht die Neigung der Rührwerkachse eine Mitnahme von Füllgut, welches oberhalb der Äquatorebene des Behälters liegt, was zu einer besseren Durchmischung des Füllgutes führt. Gleichzeitig ermöglicht die senkrecht zur Rührwerkachse stehende Trennebene und die entsprechend dimensionierten Rührorgane die vollständige Freilegung der oberen Behälterschale beim öffnen.The advantages of the mixer dryer according to the invention are immediately apparent to the person skilled in the art. On the one hand, the inclined arrangement of the agitator leads to better mixing and on the other hand allows the complete exposure of the upper container shell when opening the container proper cleaning of the same. In particular, the inclination of the agitator axis allows entrainment of contents, which lies above the equatorial plane of the container, which leads to a better mixing of the contents. At the same time, the separating plane perpendicular to the agitator axis and the correspondingly dimensioned agitating elements make it possible to completely expose the upper container shell when it is opened.
Im Folgenden soll die Erfindung anhand eines Ausführungsbeispieles und mit Hilfe der Figur näher erläutert werden. Dabei zeigt:In the following, the invention will be explained in more detail using an exemplary embodiment and with the help of the figure. Showing:

An outlet valve 13 is arranged in the lowermost region of the lower container shell 3. According to the invention, the two container shells 2, 3 can be closed in a parting plane T. , this separation plane T being substantially perpendicular to the agitator axis R, ie inclined to the horizontal equator plane H. This separation plane T can also be seen as the boundary surface of the envelope for the movements of the stirring elements 12, 12 ', 12 ". It proves to be particularly advantageous that the hinge joint 14 can be arranged in this parting plane T, because it allows the contour of the stirring elements 12, 12 ', 12 "of the inner contour of the container B to follow more precisely, ie with the least possible tolerance. in that a locking device 15 is arranged on the side opposite the hinge joint 14.
In einer Weiterbildung des vorliegenden Kugelmischers 1 sind die Rührwerkwelle 11 und die Rührorgane 12, 12', 12" mit Kanälen versehen, welche es erlauben, ein heisses Fluid 16 in diesen Organen zirkulieren zu lassen. Wesentlich für die Erfindung ist es, dass die Rührorgane 12, 12', 12" die untere Behälterschale 3 resp. die Trennebene T nicht überragen, um sicherzustellen, dass beim öffnen des Behälters B diese Rührorgane 12, 12', 12" die Innenfläche der oberen Behälterschale 2 vollständig freigeben.In a development of the present ball-type mixer 1, the agitator shaft 11 and the stirring elements 12, 12 ', 12 "are provided with channels which allow a hot fluid 16 to circulate in these organs 12, 12 ', 12 ", the lower container shell 3 respectively. do not project beyond the dividing plane T, in order to ensure that upon opening of the container B these stirring elements 12, 12 ', 12 "completely release the inner surface of the upper container shell 2.
Für die Praxis weisen die Behälter dieser Kugeltrockner ein Volumen von 400 bis 4'00O Liter auf. Insbesondere werden damit Granulate oder pulverförmige Substanzen für die Pharma oder Lebensmittelindustrie gefertigt, d.h. sind hohe Anforderungen an die Reinheit des Behälters gestellt. In practice, the containers of these ball dryers have a volume of 400 to 4,000 liters.
