Vertical Centrifuge - Dryer Typ CDR for pharmaceutical production

Centrifuge - Dryer type CDR is made according to GMP conditions as multi-purpose machine for centrifuging ( separation of solids from liquids ) and vacuum drying of product in one working space. It provides a closed system to be used for poor filtering or toxic products

All equipment is prepared for electro-pneumatic execution:

  • lid opening
  • scraping of product
  • feed control system
  • peripherical armatures e.g. valves


  • stainless steel 1.4404, 1.4435
  • spezial alloy 2.4602 ( Hastelloy C-22 )

Surface quality:

  • grinded Ra < 0,8 µm
  • polished Ra < 0,2 µm


  • CIP nozzles for cascade cleaning
  • flooding of process housing

Discharge of solids:

  • bottom discharge system

Variable accessories can be:

  • electric operation system
  • bottom discharge with pneumatic support
  • heating - cooling system
  • milling of product
  • vacuum drying of product
  • gastight design, suitable for purging of nitrogen (ATEX-Ex II 2G IIC T4/Ex II 2D IIB T4)

Additional accessories:

  • filling (Valves, compensators,hoses etc. )
  • washing(Valves, compensators,hoses etc. )
  • purging with nitrogen (pressure limit switches, O2-analyser)
  • installation of dryer (standby unit)
