PLANEX System® - paddle vacuum dryer Back

Planex System® is based on an innovative philosophy of working, especially suitable for vacuum drying of wet powders obtained from centrifuge or filter press and it is directed to Active Pharmaceutical Ingredients, Fine Chemical and Intermediates treatment.
Planex Sistem® consists of a fixed cylindrical chamber with an eccentric agitator inside with two independent movements, able to rotate on its own 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 solvents release is facilitated and drying times are significantly reduced compared to conventional systems.
The peculiar configuration of the agitator, characterized by a diameter much smaller than the one of the drying chamber, and the double rotation not only allow the continuous revolution of the product but also limit the mechanical and thermal stress, preventing local overheating due to friction. This enables to treat even more delicate and thermo sensitive products, as it preserves their purity, avoiding degradation of the dried batch.
