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

Highlights

  • 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
