Abstract
Description
Die Erfindung betrifft einen Vakuum-Trockenschrank nach dem Oberbegriff des Anspruchs 1.The invention relates to a vacuum drying cabinet according to the preamble of Claim 1.
Ein Trockenschrank dieser Art ist durch die DE 713 607 C bekannt geworden. Er besitzt mehrere übereinander angeordnete Kammern, von denen jede aus einem einstückigen Blechstreifen besteht, der durch Abbiegen zu einem rechteckigen Hohlprofil geformt wird. Die jeweils aneinanderstoßenden Stimkanten des Blechstreifens werden durch eine Schweißnaht miteinander verbunden. Die Kammern werden von mit dem Trockenschrankgehäuse verbundenen Rahmen getragen bzw. aufgenommen und sind sowohl vome als auch hinten offen, was somit zwei Einführungsöffnungen erfordert. Entsprechend diesen Einführungsöffnungen werden mittels die Rahmen ergänzenden Rahmenteilen Stimwände gebildet. Zur Abstützung der Kammern gegen das umfassende Gehäuse und zur Führung des die kompletten Kammem umspülenden Heizmediums sind Stützteile erforderlich. Außerdem sind zum Ausgleich der Kräfte aufgrund des Vakuums in den Kammern auf alle Ober- und Unterseiten der Kammern Stege geschweißt, die mit Bohrungen versehen sind, durch die zur Verbindung zudem auch noch Stehbolzen geschlagen werden. Weiterhin sind die äußeren horizontalen Blechstreifen der jeweils obersten und untersten Kammer über Profileisen stehbolzenartig mit dem Gehäuse verbunden, um eine ausreichende Festigkeit gegen den äußeren Luftdruck zu erhalten. A drying cabinet of this type has become known from DE 713 607 C. He has several chambers one above the other, each of which is made up of one one-piece sheet metal strip, which by bending into a rectangular Hollow profile is formed. The abutting ends of the sheet metal strip are connected by a weld. The chambers are carried by frames connected to the drying cabinet housing or recorded and are both open from the front and back, which is two Entry openings required. According to these insertion openings by means of frame parts complementing the frame end panels. For support of the chambers against the comprehensive housing and for guiding the Supporting parts are required for the entire chamber around the heating medium. Moreover are to balance the forces due to the vacuum in the chambers Crossbars welded to all upper and lower sides of the chambers, with holes are provided, through which stud bolts are also struck for connection become. Furthermore, the outer horizontal metal strips are each top and bottom chamber above profile iron stud-like with the Housing connected to provide sufficient strength against external air pressure to obtain.
Es sind weiterhin auch solche Trockenschränke seit langem bekannt, die einen großen Vakuum-Raum aufweisen, in dem Heiz- und/oder Kühlplatten eingeschraubt bzw. eingeschweißt sind. Die Heiz- und/oder Kühlplatten liegen dabei auf Stützleisten, die innen an den Seitenwänden des Schrankes vorgesehen sind. Die Leitungen für das die Heiz- und/oder Kühlplatten speisende Wärmeübertragungsmedium sind durch die Schrankrück- bzw. Seitenwand geführt. Die Seitenwände des Trockenschranks werden durch massive Leisten stabilisiert, um eine Implosion zu verhindern.Such drying ovens have also long been known, some of them have a large vacuum space in which heating and / or cooling plates are screwed or are welded. The heating and / or cooling plates rest on it Support strips that are provided on the inside of the side walls of the cabinet. The Lines for the heat transfer medium feeding the heating and / or cooling plates are led through the back or side wall of the cabinet. The sidewalls of the drying cabinet are stabilized by massive ledges to prevent an implosion to prevent.
Ein Nachteil dieser bekannten Trockenschränke ist, daß die Zuführung für das Wärmeübertragungsmedium zu den Heiz- und/oder Kühlplatten durch den Vakuumschrank geführt sind, wodurch aufwendige Dichtungen notwendig werden. Derartige Vakuum-Trockenschränke werden zum Trocknen von pharmazeutischen oder chemischen Präparaten bzw. Lebensmitteln eingesetzt. Eine wichtige Voraussetzung für diesen Einsatz ist, daß der Innenraum des Vakuum-Trockenschranks sehr sauber gehalten wird. Dazu werden bereits automatische Reinigungsanlagen angeboten. Ein weiterer Nachteil des bekannten Vakuum-Trockenschrankes sind die vielen verdeckten bzw. durch die Reinigungsanlage nicht erreichbare Stellen, z. B. an den Ein- und Auslässen des Wärmeübertragungsmediums oder an den Auflagebereichen der Heiz- und/oder Kühlplatten auf den Stützleisten. Nachteilig sind weiterhin die materialaufwendigen Versteifungen für den Vakuum-Trockenschrank, die diesen zudem extrem schwer machen.A disadvantage of these known drying cabinets is that the feed for Heat transfer medium to the heating and / or cooling plates through the vacuum cabinet are performed, making complex seals necessary. such Vacuum drying ovens are used for drying pharmaceutical or chemical preparations or food. An important requirement for this use is that the interior of the vacuum drying cabinet is kept very clean. These are already automatic Cleaning equipment offered. Another disadvantage of the well-known vacuum drying cabinet are the many hidden or through the cleaning system unreachable places, e.g. B. at the inlets and outlets of the heat transfer medium or on the contact areas of the heating and / or cooling plates the support strips. Are disadvantageous furthermore the material-intensive stiffeners for the vacuum drying cabinet, which also make it extremely difficult.
Es wurden auch schon Vakuum-Trockenschranksysteme vorgeschlagen, die aus einer Vielzahl kleiner, aufeinander angeordneter Schränke zusammengestellt worden sind. Nachteilig bei diesen kleinen Vakuum-Trockenschränken ist, daß jeder Schrank eine Evakuierungsleitung und entsprechende Manometer usw. benötigt. Hinzu kommt, daß jeder Schrank eine eigene Tür aufweist, so daß ein maschinelles Befüllen und gegebenenfalls Reinigen durch die vielen zu öffnenden Türen stark behindert wird.Vacuum drying cabinet systems have also been proposed, that of a multitude of small, stacked cabinets have been put together. A disadvantage of these small vacuum drying ovens is that every closet has an evacuation line and appropriate pressure gauges etc. are required. On top of that everyone Cabinet has its own door, so that a machine filling and cleaning if necessary through the many doors that can be opened is severely disabled.
Der Erfindung liegt die Aufgabe zugrunde, einen Vakuum-Trockenschrank der gattungsgemäßen Art so auszubilden, daß er leicht, auch maschinell, zu reinigen sowie mit geringem Aufwand und kostengünstig zu erstellen ist.The invention has for its object a vacuum drying cabinet of the generic type so that it is easy, too mechanically, to clean and with little effort and inexpensive is to be created.
Diese Aufgabe wird durch die Merkmale des Anspruchs 1 gelöst. Die einzelnen Mulden bilden dabei, miteinander verbunden, den Vakuum-Raum. Die Zu- und Ableitungen für das Wärmeübertragungsmedium sind zwischen den Ober- und Unterblechen der Heiz- und/oder Kühlplatten außerhalb des Vakuum-Raums angeschlossen. Die durch die abgebogenen Seitenstreifen gebildeten Mulden sind frei von Ecken, Absätzen und unzugänglichen Bereichen, so daß eine manuelle und/oder maschinelle Reinigung problemlos optimal erfolgen kann. Hinzu kommt, daß die Ober- und Unterbleche speziell behandelt, z.B. poliert sein können, so daß eine Reinigung der Flächen zudem noch besser möglich ist. Die Mulden stützen sich gegenseitig ab und sind durch die zwischen ihnen angeordneten Zwischenleisten und Seitenleisten so stabilisiert, daß keine aufwendigen Versteifungen als Implosionsschutz notwendig sind. Hier können selbstverständlich auch widerstandspunktgeschweißte Leichtbauplatten als Heiz- und/oder Kühlplatten eingesetzt werden. This object is solved by the features of claim 1. The Individual troughs, connected to each other, form the vacuum space. The inlets and outlets for the heat transfer medium are between the top and bottom plates of the heating and / or cooling plates connected outside the vacuum space. The through the bent Troughs formed are free of corners, shoulders and inaccessible areas, so that a manual and / or machine Cleaning can be done optimally without any problems. In addition, the Top and bottom plates specially treated, e.g. can be polished so that cleaning of the surfaces is also even better possible. The troughs support each other and are by the between stabilized intermediate strips and side strips arranged so that no expensive stiffeners as protection against implosion are necessary. Of course you can also use resistance welded here Lightweight panels as heating and / or cooling panels be used.
