Abstract

Gegenstand der Erfindung ist eine Horizontale Gefriertrocknungsanlage mit einer Produktkammer (10), an die seitlich oder rückwärtig (horizontal) eine Kondensatorkammer (12) angeschlossen ist, und mit einer Anzahl von in der Produktkammer (10) vorgesehenen Stellplatten (16) zur Aufnahme von Gefriertrocknungsgut, wobei in einer gemeinsamen, vertikal ausgerichteten Zwischenwand (22) von Produktkammer (10) und Kondensatorkammer (12) eine Verbindungsöffnung (24) ausgebildet ist, welche über ein Zwischenventil (22) verschließbar ist. Eine Gefriertrocknungsanlage zu schaffen, bei der das zu evakuierende Medium aus allen Bereichen der Produktkammer möglichst gleichmäßig und widerstandsarm herausströmen kann, um das in der Produktkammer befindliche Gefriertrocknungsgut möglichst gleichmäßig gefrier zu trocknen, wird dadurch erreicht, dass die Höhe der Verbindungsöffnung (24) in mindestens 70 %, vorzugsweise 100 %, der Höhe der Stellplatten (16) entspricht.

The invention relates to a horizontal freeze-drying plant with a product chamber (10) to which a condenser chamber (12) is connected laterally or rearwardly (horizontally), and with a number of in the product chamber (10) provided for adjusting plates (16) for receiving Gefriertrocknungsgut , wherein in a common, vertically oriented intermediate wall (22) of the product chamber (10) and condenser chamber (12) has a connection opening (24) is formed, which via an intermediate valve (22) is closable. To provide a freeze-drying plant in which the medium to be evacuated from all areas of the product chamber can flow out as evenly and low resistance to freeze the freeze-dried product contained in the product chamber as uniformly freeze is achieved in that the height of the connection opening (24) in at least 70%, preferably 100%, the height of the adjusting plates (16) corresponds.
