Pan dryer – Multidry EV

Drying is a common process step required after a solid-liquid separation. Vacuum drying is the most efficient and effective means to obtain this for most pharmaceutical and chemical products, facilitating the processing of thermal sensitive substances as well.
Our agitated vacuum dryers ensure homogenous mixing of the product, improving the heat exchange factor and, as a final result, further reducing the drying time.

The pan dryer, thanks to the increased heat exchange surface, ensures optimum drying time while the agitator shape reduces product clumps.
It can be used for products with varying chemical-physical properties.

All operations are conducted without exposing operators to the products and without contaminating the product itself, ensuring safety and quality at the same time.
We provide special solutions to keep the process fully contained also during the product filling and discharge phases.

Our dryers are effectively used in multiple applications across the following different industries:

  • Biochemicals
  • Crop protection
  • Flavours & fragrances
  • Food & beverage
  • Pharmaceutical
  • Polymers
  • Precious and technology metals
  • Waste recovery

Depending on the product and/or application, different kinds of agitators or dryer shapes can be designed and drying can also be combined with filtration in a single unit, for even higher efficiency and product containment, as ensured by our pressure filter dryers.

More about filter dryers

Dryers or filter dryers can be provided as standalone units or modular turnkey systems to simultaneously satisfy functional needs and efficiency in project costs and execution time.
