Definitions

  • Such liquids are added, for example, in the pharmaceutical industry during the coating process.
  • Tablet cores are usually coated with a polymer film containing color pigment. This is done on the one hand to influence the mechanical properties of the tablets favorably, to achieve better swallowability of tablets and to mask unpleasant taste effects of active ingredients, and on the other hand to modify the active ingredient release of tablets (e.g. enteric coatings or retarding coatings).
  • enteric coatings or retarding coatings e.g. enteric coatings or retarding coatings.
  • the liquid spray cone emerging from the respective nozzle is detected by means of an electro-optical monitoring unit and compared with a reference image.
  • a spray pattern check can automatically ensure that the liquid is sprayed evenly onto the solid in the desired distribution.
  • Each nozzle that generates a corresponding spray cone of the liquid to be sprayed on is advantageously assigned a corresponding electro-optical monitoring unit.
  • a correspondingly movable electro-optical monitoring unit can be provided, which cyclically moves nozzles arranged next to one another and checks them in a predetermined time cycle.
  • the electro-optical monitoring unit can consist of a device for emitting light and a receiving device for receiving the spray pattern information.
  • the device for recording the spray image can consist of a video camera.
  • the current spray image information can be compared with stored image information in a predetermined cycle, for example in a 5 second cycle, in order to detect any deviations that may have arisen.
  • the parts of the electro-optical monitoring unit which are arranged in the vicinity of the monitored liquid spray cone are advantageously encapsulated in order to protect them from the spray mist within the process space.
  • a gas overpressure can advantageously also be generated within this encapsulation for the encapsulated parts of the electro-optical monitoring unit, so that a laminar gas flow to the external environment of the encapsulation is established.
  • This laminar flow can advantageously be generated with sterile compressed air.
