VVD - Vertical vacuum dryer

VVD: DRYING ANT NOTHING ELSE

The VVD Delta Vertical Vacuum Dryer is a machine that has been designed with a singular purpose: to vacuum dry. The VVD is equipped with several focused devices that allow the customer to obtain a perfect drying process

THE AGITATOR IS IMPORTANT

The VVD Delta Vertical Vacuum Dryer main features are linked with the agitator. Its 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.

These features

VVD AT GLANCE

The VVD Delta Vertical Vacuum Dryer is composed of the following elements:

  • The cylindrical body, equipped with a convex top head and a flat bottom head, constitutes the machine core, and is certified as a pressure vessel. Depending on batch size and on the available installation location, Delta offers a totally customized design.
  • The agitator is fundamental for each operation. Located on the top head, it can rotate in both directions and can be lifted or lowered, according to process needs.
  • The Delta VVD plug discharge valve, positioned on the body side at the flat head level. The design features are derived from extensive experience and process knowledge. Manually or automatically driven, it can be adapted to both main packaging and high-containment devices

APPLICATION FIELDS

The VVD Delta Vertical Vacuum Dryer is suitable for multi-product or mono-product applications accomplished in batch process. Due to its robust and reliable design, it can be used in many industries, such as:

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

CUSTOMIZATON IS OUR BIBLE

Delta has developed standard VVD Delta Vertical Vacuum Dryer machine configurations to adhere to the specific production needs for several applications and industries:

  • cGMP and EHEDG, for API production, but also for fine chemicals and fragrances
  • cGMP sterile for sterile API production
  • pilot plant, for small batches for research and development

In addition, Delta offers a wide production range for the DVRF Delta Horizontal Vacuum Dryer:

  • Operating volume: from 10 liters to 15 m3
  • Contact material: AISI316L, AISI904L, C-22, C-276, coated with elastomers
  • Surface finishing: from pickled and passivated to mirror polished
  • Sealing system: from stuffing box to lift off mechanical seal
  • Certification: PED, ASME, HP0, Selo, ATEX

 

As per the Delta Costruzioni Meccaniche philosophy, each machine can be completely customized to the customer’s needs. The following list of VVD Delta Vertical Vacuum Dryer options is only a fraction of the solutions that Delta has developed over the years:

  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 tends lumps generation
  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.
