New Ways in Product Drying

Mechanical and thermal stresses on the product are significantly lower than those observed in traditional paddle dryers equipped with concentric agitator (Picture: Italvacuum)

Italvacuum's patented Planex System is a new concept multi product dryer, developed for vacuum drying of wet powders obtained from centrifuge or filter press, especially suitable for the production of Active Pharmaceutical Ingredients, Fine Chemicals and Intermediates.

The system consists of a fixed cylindrical chamber with an eccentric agitator inside with two independent movements, able to rotate on its own axis and tangentially to the cylindrical chamber as well. The double combined rotation allows an optimal mixing of the product, continuously renewing the surface of the mass exposed to evaporation, covering all the volume of the vessel. In this way the release of solvents vapours is facilitated and drying times are significantly reduced compared to conventional systems.

With the new layout, the mechanical and thermal stress on the product is significantly lower than the one observed in traditional paddle dryers equipped with concentric agitator, with consequent reduction of the electricity consumption. A CIP system allows a complete washing of all the parts in contact with the product for easy internal cleanability.
