deCON - decontamination dryer for foodgrade flakes

deCON | deCON iV+

Decontamination dryer for production of dry, iV-increased food grade flakes from bottles and trays, or skeleton waste directly in front of a production extruder. The deCON iV+ is the optimal tray recycling solution, with a production mode for intrinsic viscosity (iV) increase.


deCON benefits:

  • Decontamination of post-consumer recycled flakes according to EFSA and FDA
  • iV increase mode for tray recycling
  • Excellent dedusting
  • Drying to below 50 ppm
  • Controlled and consistent residence time (FIFO)
  • Low power consumption and maintenance


  1. stand alone
  2. in front of production extruder
  3. optional crystalizer

    Above table represents general technical data and average values, which depend on chemical composition, contamination, pelletizing, etc. of the pellets/flakes. Guaranteed values only after trial with customer material. The calculated electrical power rate refers only to the reactor and periphery of the reactor and depends on the output rate.  We reserve the right of technical modification.
