Vertical Vacuum Dryer

Vertical Vacuum Dryer

Vertical Vacuum Dryer

The Vertical Vacuum Dryer (or Agitated Vacuum Pan Dryer) is ideal for small batches of high viscosity product within the pharmaceutical and chemical industries.

When a static or tray dryer doesn’t work, adding an agitator can overcome difficulties such as viscous or pasty phases, allowing for a more efficient drying process.

This dryer is a flexible, compact, and robust machine that has been designed with a singular purpose: to vacuum dry. It is equipped with several focused devices that allow the customer to obtain a perfect drying process.

Typical Applications

  • API production
  • Fine chemicals
  • Plastics
  • Dietary supplements/fragrances
  • Chemical Intermediates
  • Precious metals/Metals recycling
  • Catalysts


  • The agitator’s special design allows:
    • moving the cake during the drying process
    • rotating at a variable speed
    • applying a vertical movement where possible
    • being heated for a better drying process
    • automatically discharging the product
  • Suitable for multi-product or mono-product applications accomplished in batch process
  • cGMP, cGMP sterile, and EHEDG designs
  • Designed for easy cleaning and inspection
  • The plug discharge valve can be manually or automatically driven, and can be adapted to both main packaging and high-containment devices

Custom Options

  1. CIP system: For washing between batches, which uses rotating spray balls and sprayers on critical areas of the discharge valve
  2. SIP system: Steams inside the machine body and checks cold area temperatures for sterilizing grade control
  3. Sanitary insulation: Which is mandatory for applications where cleanliness is important, like in white chambers (clean rooms)
  4. Sampling device: For retrieving a product sample and checking the production status
  5. Delumper: For products that tend to form lumps
  6. Dust filter on the top head: For product capture while avoiding vacuum pump contamination
  7. High containment devices: For high-potency products, such as a glove box at the discharge nozzle or at the sampling port
  8. Flat bottom lowering and bayonet closure system: For easy maintenance management
  9. External vacuum system coupled with an integrated heating system: For global production line management
