Abstract

A vacuum drying cupboard incorporates shelves constructed as heat exchangers which maintain the temp. at a required level. The upper and lower shelf panels are sheet metal. Adjacent upper and lower shelves are joined by their ends and the cavity within each shelf contg. the heat transfer fluid medium is sub-divided into sections by intermediate structures. The novelty is that (a) the ends (11-14) of the upper shelf face (5) metal panel and the lower face (6) metal panel are extended to form side-strips, (b) that the end edges (11,13) of each upper panel (5) and the end-edges (12,14) of the lower panel (6) contact the neighbouring heating/cooling surface (4) to form a vacuum-tight join, (c) the outer upper panel (5') and the outer lower panel (6') are fabricated without any significant side-strip, (d) the depressions (2-2""") formed by the upper (5) and lower (6) panels and the side strips (11-14) are held by a frame (15,150) within the door (3,30) and together form a vacuum chamber.

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.

Derartige Trockenschränke sind seit langem bekannt. Sie weisen einen großen Vakuum-Raum auf, 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 been known for a long time. They have a large vacuum space in which heating and / or cooling plates are screwed or welded. The heating and / or cooling plates lie on support strips which 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 cabinet rear or side wall. The side walls of the drying cabinet are stabilized by solid strips to prevent implosion.

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-Trockenschranks sind die vielen verdeckten bzw. durch die Reinigungsanlage nicht erreichbaren Stellen, z.B. an den Ein- und Auslässen des Wärmeübertragungsmediums oder an den Auflagebreichen 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 supply for the heat transfer medium to the heating and / or cooling plates is led through the vacuum cabinet, which makes expensive seals necessary. Vacuum drying cabinets of this type are used for drying pharmaceutical or chemical preparations or foods. An important prerequisite for this application is that the interior of the vacuum drying cabinet is kept very clean. Automatic cleaning systems are already being offered for this purpose. Another disadvantage of the known vacuum drying cabinet are the many concealed or inaccessible places, for example at the inlets and outlets of the heat transfer medium or at the support areas of the heating and / or cooling plates on the support strips. Are disadvantageous Furthermore, the material-intensive stiffeners for the vacuum drying cabinet, which also make it extremely heavy.

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 which have been put together from a large number of small cabinets arranged one on top of the other. A disadvantage of these small vacuum drying cabinets is that each cabinet requires an evacuation line and corresponding pressure gauges etc. In addition, each cabinet has its own door, so that mechanical filling and possibly cleaning is severely hampered by the many doors that need to be opened.

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 to design a vacuum drying cabinet of the generic type so that it is easy to clean, even mechanically, and to create with little effort and inexpensive.

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 supply and discharge lines for the heat transfer medium are connected between the top and bottom plates of the heating and / or cooling plates outside the vacuum space. The depressions formed by the bent side strips are free of corners, shoulders and inaccessible areas, so that manual and / or machine cleaning can be carried out optimally without any problems. In addition, the top and bottom plates can be specially treated, for example polished, so that the surfaces can also be cleaned even better. The troughs are mutually supported and are so stabilized by the intermediate strips and side strips arranged between them that no complex stiffeners are necessary as protection against implosion. Of course, resistance-spot-welded lightweight panels can also be used here as heating and / or cooling panels.

Weiter vorteilhafte Ausgestaltungen ergeben sich, wenn die Merkmale der Unteransprüche bei einem erfindungsgemäßen Vakuum-Trockenschrank verwirklicht werden.Further advantageous configurations result if the features of the subclaims are realized in a vacuum drying cabinet according to the invention.

Besonders vorteilhaft sind die Merkmale des Anspruchs 4 in seiner Rückbeziehung auf Anspruch 3 oder die des Anspruchs 5. Bei einer derartigen Ausgestaltung des Beruhigungsraumes kann die Evakuierungsleitung fest am Rahmen angeschlossen werden, so daß keine beweglichen Zuführungen notwendig werden.The features of claim 4 are particularly advantageous in relation to claim 3 or that of claim 5. With such a configuration of the calming space, the evacuation line can be firmly connected to the frame, so that no movable feed lines are necessary.

Fig. 1 zeigt einen Vakuum-Trockenschrank 1, welcher aus einer Anzahl von Mulden 2 bis 2''''' und einer Tür 3 gebildet wird. Die Mulden 2 weisen Heiz- und/oder Kühlplatten 4 auf, die von Oberblechen 5 und Unterblechen 6 gebildet werden. Zwischen den Oberblechen 5 und den Unterblechen 6 sind Zwischenleisten 7 und Seitenleisten 8 angeordnet, über die die Oberbleche 5 und Unterbleche 6 miteinander verbunden sind und die die Heiz- und/oder Kühlplatten 4 seitlich abschließen. An die Heiz- und/oder Kühlplatten 4 sind Zu- und Abflüsse 9 für das Wärmeübertragungsmedium angeschlossen, die in einen gemeinsamen Vor- bzw. Rücklauf 10 münden. Der Durchsatz des Wärmeübertragungsmediums durch die Heiz- und/oder Kühlplatten 4 wird durch die Anordnung und die Abstände zwischen den Zwischenleisten 7 und den Seitenleisten 8 bestimmt.Fig. 1 shows a vacuum drying cabinet 1, which is formed from a number of troughs 2 to 2 '''''and a door 3. The troughs 2 have heating and / or cooling plates 4, which are formed by top plates 5 and bottom plates 6. Between the top plates 5 and the bottom plates 6, intermediate strips 7 and side strips 8 are arranged, by means of which the top plates 5 and bottom plates 6 are connected to one another and which laterally close off the heating and / or cooling plates 4. To the heating and / or cooling plates 4 are feed and Drains 9 connected for the heat transfer medium, which open into a common flow or return 10. The throughput of the heat transfer medium through the heating and / or cooling plates 4 is determined by the arrangement and the distances between the intermediate strips 7 and the side strips 8.

Die Oberbleche 5 und Unterbleche 6 sind an drei ihrer Seiten abgebogen und bilden Seitenstreifen 11, 12, 13, 14, deren Stirnflächen aufeinander ausgerichtet sind. Die Seitenstreifen 11 der Oberbleche 5 sind mit ihren Seitenstreifen 13 und mit den Seitenstreifen 12 der Unterbleche vakuumdicht verschweißt. Ähnlich sind die Seitenstreifen 14 der Unterbleche mit ihren Seitenstreifen 12 und den Seitenstreifen 13 der Oberbleche 5 verschweißt. Lediglich das äußerste Oberblech 5' und das äußerste Unterblech 6' sind ohne wesentliche Seitenstreifen ausgeführt.The top plates 5 and bottom plates 6 are bent on three of their sides and form side strips 11, 12, 13, 14, the end faces of which are aligned with one another. The side strips 11 of the top plates 5 are welded to their side strips 13 and to the side strips 12 of the bottom plates in a vacuum-tight manner. Similarly, the side strips 14 of the bottom plates are welded to their side strips 12 and the side strips 13 of the top plates 5. Only the outermost top plate 5 'and the outermost bottom plate 6' are designed without substantial side strips.

Die Mulden 2 bis 2''''' sind von einem gemeinsamen Rahmen 15 umgeben, der den Abschluß der Mulden 2 bis 2''''' zur Tür bildet. Die Deckfläche 16 der Tür 3 ist zur Bildung eines Beruhigungsraums 17 zurückgesetzt. An der Deckfläche 16 ist ein Anschlußstutzen 18 für die Evakuierungsleitung des Trockenschranks vorgesehen.The troughs 2 to 2 '' '' 'are surrounded by a common frame 15 which forms the closure of the troughs 2 to 2' '' '' to the door. The top surface 16 of the door 3 is set back to form a calming space 17. On the top surface 16, a connection piece 18 is provided for the evacuation line of the drying cabinet.

Fig. 2 zeigt eine Tür 30, die keinen Beruhigungsraum aufweist. Dafür weist jedoch der Rahmen 150 vor der Front der Mulden 2 einen Beruhigungsraum 170 auf. Am Rahmen 150 ist ein Anschlußstutzen 180 vorgesehen, der über nicht gezeigte feste Leitungen mit der Vakuumpumpe verbunden ist.Fig. 2 shows a door 30, which has no relaxation room. For this purpose, however, the frame 150 has a calming space 170 in front of the front of the troughs 2. On the frame 150, a connection piece 180 is provided, which is connected to the vacuum pump via fixed lines, not shown.

Fig. 3 zeigt einen Vakuum-Trockenschrank, der von zwei Seiten beschick- und reinigbar ist. Auf beiden Seiten der Mulden 20 sind umlaufende Rahmen 15, 15' vorgesehen. Der Schrank wird durch Türen 3, 30 verschlossen. Im Gegensatz zum Schrank nach Fig. 1 müssen die Zu- und Ableitungen für das Wärmeübertragungsmedium bei diesem Schrank nicht an der Vorder- oder Rückfront, sondern an den Seiten angebracht sein. Außerdem ist hier eine weitere Möglichkeit der Anbringung des Anschlußstutzens 180' gezeigt. Auch hier ist, wie beim anschlußstutzen 180 nach Fig. 2 ein fester Anschluß der Vakuumleitung möglich.Fig. 3 shows a vacuum drying cabinet, which can be loaded and cleaned from two sides. Circumferential frames 15, 15 'are provided on both sides of the troughs 20. The cabinet is closed by doors 3, 30. In contrast to the cabinet according to FIG. 1, the supply and discharge lines for the heat transfer medium in this cabinet do not have to be on the front or rear front, but on the sides to be appropriate. In addition, another possibility of attaching the connection piece 180 'is shown here. Here too, as with the connection piece 180 according to FIG. 2, a fixed connection of the vacuum line is possible.

Es besteht selbstverständlich auch die Möglichkeit, einen der Rahmen 15 durch einen Rahmen 150 zu ersetzen und an beiden Seiten Türen 30 vorzusehen. Weitere Alternativen sind z.B., daß zwei Rahmen 150 und zwei Türen 30 oder aber lediglich zwei Türen 3 vorgesehen werden. Auch eine Kombination von Rahmen 150 mit Türen 3 ist denkbar.It is of course also possible to replace one of the frames 15 with a frame 150 and to provide doors 30 on both sides. Other alternatives are, for example, that two frames 150 and two doors 30 or only two doors 3 are provided. A combination of frame 150 with doors 3 is also conceivable.

In den Zeichnungen wird aus Übersichtlichkeitsgründen nicht gezeigt, daß die Türen (3, 30) und/oder der Rahmen 150 und/oder die Seitenstreifen (11 - 14) mit Heiz- und/oder Kühlvorrichtungen ausgestattet sein können, um ein Kondensieren der abzusaugenden Brüden an den Wänden zu verhindern.For reasons of clarity, the drawings do not show that the doors (3, 30) and / or the frame 150 and / or the side strips (11-14) can be equipped with heating and / or cooling devices in order to condense the vapors to be extracted to prevent on the walls.
