Definitions

  • the present invention relates to a drying device for containers, in particular for bottles, according to the features of the preamble of claim 1. Furthermore, the invention relates to a method for cleaning such a drying device.
  • a device for drying objects is in DE 102008004774 A1 described. Air supply openings for supplying drying air and at least one exhaust air opening for removing moist exhaust air are provided in a drying chamber. In particular, this device provides an internal air duct which is directed past the inlet and / or outlet opening for the objects to be dried. Another device known from the prior art for drying objects is shown in WO 82/03832 A1 disclosed.
  • the drying modules must therefore be cleaned regularly, preferably at least once a day, in order to avoid increased nucleation and contamination.
  • the cleaning is traditionally done manually by the interior of the Drying module is sprayed with water, if necessary treated with a cleaning agent and then sprayed out again with water. This is quite time consuming and often uncomfortable for the operator performing it. Since no production can take place during this time, the intervals between cleaning are often extended. This in turn creates a higher germ load for the operators of subsequent processing stations, since the germs find improved conditions for their growth.
  • the object of the invention is to be able to carry out a simple, quick and inexpensive cleaning of drying modules.
  • the invention relates to a device for drying containers, in particular a drying module for drying empty or filled beverage bottles or the like. in a container treatment and / or filling system.

  • the higher-level system activates the control module in particular when, for example, the system is at least partially due to a product change needs to be converted.
  • the cleaning intervals can thus be set individually via the time, start / end of production etc. or manually.
  • the inlet and outlet openings can be largely sealed off by means of closure devices during the cleaning of the drying chamber, so that the interior of the drying chamber forms a closed system.
  • closure devices can prevent cleaning agents from escaping during the cleaning process and thus contaminating the surroundings of the device.
  • This further improves the safety of the personnel operating the device.
