RotoCone Vacuum Dryer

Gentle rotating vacuum drying with integrated solvent recovery — the gold standard for pharmaceutical API drying.

RotoCone Vacuum Dryer

About the RotoCone Vacuum Dryer

The RotoCone Vacuum Dryer (RCVD) combines the gentle tumbling action of a rotating double-cone with the thermal efficiency of high-vacuum operation. Under vacuum, solvent boiling points are significantly reduced — allowing drying at substantially lower temperatures than atmospheric dryers. This protects heat-sensitive active pharmaceutical ingredients from thermal degradation while achieving thorough, uniform moisture removal.

The continuous rotation ensures every particle is constantly exposed to the heated surface, preventing hot spots and delivering a completely homogeneous final product. An integrated condenser and solvent receiver captures evaporated solvents for recovery and reuse. The sealed, contained system ensures zero dust generation — making it ideal for toxic, potent or sterile materials.

Key Applications

Core Advantages

Low-Temperature Operation
High vacuum significantly reduces solvent boiling points — protects thermally sensitive APIs from degradation.
Uniform Drying
Continuous rotation ensures even heat exposure — no hot spots, no case hardening, homogeneous moisture profile.
