Definitions

  • the invention relates to a method for drying small objects in a process container, such as closure elements for pharmaceutical purposes (stoppers), after treating the small items as well as a device to carry out this procedure, in which under an air-permeable pad is arranged for the small objects is processed inside the process container preheated air is supplied and the small items thus rearranged relative to the process container by air be that a complete drying takes place.
  • Closure elements for pharmaceutical purposes for example Stoppers are treated in such a way that they are in a Wash phase first washed with high-purity, germ-free water will. Washing can be done with or without the addition of detergents respectively.
  • the Process container first filled with the closure elements and water is added.
  • the closure elements by means of the process container supplied compressed air moves.
  • the wash water is after the Treatment process drained again. Possibly. includes in siliconizing in a second phase. To do this again hot, high-purity water is supplied, the water dosed with silicone. Then the water away.
  • a subsequent one Phase is sterilized using steam.
  • Fluid bed dryers are also known, for example from “K. Kröll: dryer and drying process, Springer publishing house 1959, p. 275 ff ", in which air constantly with such Speed up through a layer of particles flows that the particles are slightly lifted and loosened, but not to be carried away. All parts are included constantly on the move. This allows free-flowing goods, too which can also include plastics, are dried. Another disadvantage here is that the particles due to their Frequently encounter movement while doing a considerable amount Generate abrasion. In addition, these are fluid bed dryers not suitable for particles that clump together or compacting.
  • DE 42 11 485 C2 describes a method for removing Moisture from inside a solid, for example described in wood.
  • the wood is initially included a high pressure applied to the liquid mechanically drives out of the solid, and then periodically rapidly changing pressure exposed to the rest To remove moisture.
  • a high pressure applied to the liquid mechanically drives out of the solid, and then periodically rapidly changing pressure exposed to the rest To remove moisture.
  • constant Pressure changes give the risk of severe particle abrasion.
  • the present invention is based on the object Method and device for carrying out this method of the type mentioned at the outset with which with the one with the least possible technical effort achieved complete drying of small objects and as far as possible particle abrasion and compacting is avoided.
  • the invention provides that the small items pre-warmed by the processed Air dried while lying on the pad, and that at least once briefly during drying an additional air mass flow passed under the pad who lifts the small objects and turns them over.
  • the single figure shows a schematic representation of a Process container and a pressure air vessel with the corresponding Line connections. The necessary for process control Valves are not shown.
  • a process container designated 1 is for the treatment of Closure elements provided for pharmaceutical purposes.
  • the Treatment has a washing phase, possibly a siliconization phase, a subsequent sterilization phase and one itself then drying phase.
  • Subject of the present The invention is only the drying phase.
  • the process container 1 has a perforated designated 2 Support for the closure elements, e.g. Stopper (not shown).
  • the closure elements are in the process container 1 inserted through an opening (not shown).
  • the process container 1 is shown schematically by a Connection 3 off via a pipe connection and a Media tube 4 high-purity water (WFI, Water for Injection) fed. Possibly. 5 detergents are added via a connection.
  • WFI high-purity water
  • Possibly. 5 detergents are added via a connection.
  • compressed air is connected 6 via a line 7 and the media tube 4 the inside of the process container supplied, whereby the closure elements be moved in the water and thereby the washing process takes place.
  • the compressed air escapes via an exhaust air connection 15. After the washing process, the water is over a Drain 8 derived.
  • siliconization can then be carried out.
  • water is supplied to the inside of the container, which Silicone was added via a metering device 9. Then the closure elements are fed again by means of Compressed air moves. After completion of the siliconization process the water is drained again.
  • a sterilization process then takes place.
  • the Process container 1 from the top of pure steam over a Port 10 supplied.
  • the sterilization takes place at about 120 ° C for about 20 minutes at elevated pressure. After this The process container will be sterilized again to atmospheric pressure brought.
  • closure elements are then dried.
  • the inside of the process container via the Media tube 4 heated sterile air supplied via a connection 11.
