Planex Vacuum Dryer

06.04.2015 The Planex System from Italvacuum is a new concept multi-product dryer, developed for vacuum drying of wet powders obtained from a centrifuge or filter press. It is especially suitable for the production of active pharmaceutical ingredients, fine chemicals and intermediates.

The dryer is available with total volumes ranging from 300 to 4,400 l. Both small and large batches can be treated, covering all the requirements of the chemical and pharmaceutical industries. It is absolutely safe for personnel, environment and product, being designed and manufactured in compliance with the ever more severe cGMP and Atex rules. The system consists of a fixed cylindrical chamber with an eccentric agitator with two independent movements, able to rotate on its own axis and tangentially to the cylindrical chamber as well. The double combined rotation allows optimal mixing of the product, continuously renewing the surface of the mass exposed to evaporation, covering all the volume of the vessel. This facilitates the release of solvent vapours and drying times are significantly reduced compared to conventional systems. The particular configuration of the agitator, characterized by a diameter much smaller than that of the drying chamber, not only allows continuous revolution of the product but also limits mechanical and thermal stress, preventing local overheating due to friction (friction free system). The results obtained show that after discharge the system has a minimum product residual: on average it is less than 1%.

Facts For Decision-Makers:

  • 300 to 4,400 l
  • cGMP and Atex
  • < 1 % residual
