Definitions

  • the fine fractions of the dried material remaining in the vapors are then fed together with the vapors via a blower 11 to one or more cyclones 12. This is where the fine fractions of the dried material are separated.
  • the vapors leaving the cyclone or cyclones 12 are contaminated with fine dust and the pollutants formed during drying. They are returned to the dryer 8 via the pipeline 13, where they pass through the heat exchanger 7 and are heated up. This closes the almost inert vapor cycle.
