PHARMADRY®
Vacuum horizontal paddle dryer
The PHARMADRY® horizontal vacuum paddle dryer was primarily developed for  the drying of pharmaceutical ingredients and fine chemicals.
Besides its low capital investment costs major advantages of this dryer are its short cycle times, the prevention of contamination by foreign matter, its simple operation and easy validation as well as facilitated cleaning and inspection.
The dryer is particularly suited to be used in clean rooms and for sterile applications. The machines are designed and built per cGMP and FDA guidelines.
The important features of the PHARMADRY® are:
  Cylindrical, horizontal vessel with flat welded back cover and a hinged flat front door opening up over the entire vessel diameter. With the door open, the internals of the machine are fully accessible for cleaning and inspection purposes.
  All surfaces in contact with the product such as the vessel, back cover, front door, agitator and vapour filter are heated, providing very efficient heat exchange.
  The cylindrical vessel, the back cover, the front door and the agitator are machined to assure the smallest possible tolerances between agitator and vessel walls.
  Smallest possible tolerances also permit good heat exchange and prevent product adherence.
  All internal surfaces are mirror polished, to improve the flow behaviour of powdery products, the prevention of microdeposits as well as to facilitate cleaning.
  The agitator is installed at the back of the dryer, supported on one side of the vessel only
The agitator is designed to meet the
   requirements of this particular dryer type
   to assure good and even mixing action
   throughout the dryer volume, also in
   reverse operation, to provide good
   discharging characteristics and at the
   same time reduce friction on the
   product to a minimum to prevent local
   overheating as well as to prevent
   directional thrust or local product
   compression.
Speed adjustable using frequency
   converters with electric drives or control
   valves with hydraulic drives
Sealing of the agitator shaft with double
   mechanical seal or stuffing box.


        
          

  Mechanical seal: the mechanical seal is
installed on the rear cover, and is well accessible for cleaning and maintenance purposes. Dry or wet running mechanical seals may be installed.

•  Advantages of the mechanical seal:
-  Better final vacuum
-  No hazardous leakage or emissions
-  No product contamination
-  Possibility of sterile operation
-  Failure detection system for mechanical
   seal

  Stuffing box with multiple lip seals for undemanding applications.

  Solids discharge valve, plug or ball type, pneumatically operated.

  CIP and / or steam sterilization available
  Vapour filter, equipped with automatic filter back-cleaning system.
  Sample valve
  Optional choppers
  Machine controls manual, or with PLC, PC and DCS
  Electric pre-wiring of machine
  Design and manufacturing to the requirements of international organizations such as ASME, TÜV, etc.
  Environmentally sound and safe to operate
