Problems solved by technology

Difficulties related to the situation of achieving sterility also arise in the device due to the structured construction and arrangement of the support means of the rod and the components movably arranged inside the chamber
In addition to the unavoidable debris, there is also the risk of ingress of pollutants from the surrounding environment and the difficult-to-clean structural complexity of the loading and unloading plant

Embodiment Construction

[0039] figure 1 A sectional view is shown of a drying chamber 1 of a freeze-drying system, on the front side 2 of which a closable opening for loading or unloading drying containers 5, not shown with reference numerals, is located. The drying chamber 1 is connected to the condensation chamber in a manner known per se, but this will not be discussed in more detail here.

[0040] Inside the drying chamber 1 is the arrangement of the placement surfaces 3 which are held vertically displaceable in the holder 4 in a manner known per se. The placing surface 3 is used for placing the drying containers 5 , which each contain dry substances, which will be removed from the drying chamber 1 after the drying process has ended. The height position of the placement surface 3' here is indicated by reference numeral 6, which corresponds to the unloading position of the placement surface. It is important that the vertical adjustability of all resting surfaces 3 of the stand 4 is set such that...

Abstract

A device principally used for loading and unloading the utility space (3') of the drying chamber (2) of a freeze dryer, which utility space (3') is located in a pre-defined height position, is characterised by a carriage (8), which is arranged slightly above said freeze dryer and extends, during loading or unloading, transversely to a movement direction (8') and parallel to said storage surface (3') and which forms a movable guiding edge for the drying vessels (5), and by guides (7), which extend parallel to said movement direction and form rigid guiding edges for the drying vessels (5). The carriage (8) is driven by two linear motors, the respective primary parts (9) of which are rigidly connected to both ends of the carriage (8) and which at the same time support the guides (7) accommodating the secondary parts. All of the components of the devices thus defined are located within the drying chamber (1), wherein a mechanically extremely simple and low-wear design is achieved.

Description

technical field [0001] The invention relates to a loading and / or unloading device for a freeze-drying system according to the features of the preamble of claim 1 . Background technique [0002] The freeze-drying method is used in heat-sensitive items, such as pharmaceutical and biochemical products, food, etc., where the dried item is first frozen, and the crystallized ice is sublimated from the item under vacuum and re-precipitated as ice by condensation. For this purpose, the pressure, temperature and other parameters of the drying process are controlled and monitored according to a product-specific sublimation pressure profile in order to obtain a reproducible dried product. The energy required for sublimation is generally supplied by heating. [0003] Freeze-drying systems are in many cases designed for discontinuous drive and mainly consist of a drying chamber and a condensation chamber connected to the drying chamber via a closable opening, wherein the drying items ar...
