CENTRIFUGE DRYER – SPECIAL EQUPIMENT for PHARMA – CDR

Versatile Centrifuge Dryer Solutions for Pharma

CDR – CENTRIFUGE DRYER
Centrifuge – Dryer type CDR is made according to GMP conditions as multi-purpose machine for centrifuging (product separation from slurry) and vacuum drying of product in one working space. Agitators (discharger, cake detector, lid opening, armatures etc.) are with electro pneumatic execution. CDR is gas tight, pressure centrifuge for full ATEX (for example Ex II 2G IIC T4) with inertiztaion of inner space.
The advantage is space and cost savings, as several technological operations are combined into one machine (centrifuging, washing, homogenization, vacuum contact drying and product emptying). Avoided is also any crosscontamination of product.

Centrifuge Dryer for pharmaceutical industry
Material:

  • Stainless steel 1.4404 (1.4435) / 1.4571
  • special alloy 2.4602 (Hastelloy C-22)

Surface finishing:

  • Grinded Ra <0,8 μm
  • Polished Ra <0,2 μm

Working cycle of CDR is:

  • Filling of centrifuge with slurry
  • Centrifuging
  • Washing of product at basket, second centrifuging
  • Peeling of product to basket bottom
  • Raking/milling and contact drying under vacuum
  • Cooling of product
  • Pneumatic discharging/transport of dry product to product tank
Cleaning of CDR can be done:

  • CIP cascade
  • complete flooding of CDR

Accessories:

  • variable control panel
  • thermostat (heating and cooling unit)
  • inertization and blanketing system
  • vacuum product tank VPT
  • technological armatures, hoses, compenzators etc.
This CDR 500/250 we also purchase as mobile testing equipment to ensure that we are your right partner with special device centrifuge dryer for your product.
