Roto Cone Vacuum Dryer (RCVD)
The Roto Cone Vacuum Dryer is an ideal solution for drying temperature-sensitive materials, high-potency drugs, and materials that are prone to oxidation. By combining a rotating double-cone vessel with a high-vacuum environment, the RCVD achieves rapid, uniform drying at significantly lower temperatures, preserving the chemical integrity of the product.
Core Engineering & Performance
Our RCVD is designed for “Total Solvent Recovery” and gentle handling of delicate crystals or powders.
Enhanced Heat Transfer: The double-walled jacketed vessel provides uniform heating across the entire product mass. The rotating motion ensures every particle comes into contact with the heated walls.
Vacuum Efficiency: Operates under high vacuum to lower the boiling point of solvents, facilitating moisture removal at low temperatures (ideal for heat-sensitive APIs).
Cross-Contamination Prevention: The closed-loop system ensures a dust-free operation, protecting both the operator and the environment from hazardous or toxic materials.
Zero Dead Spots: The conical shape of the vessel ensures 100% discharge of material, leaving no residue behind.
Solvent Recovery: Can be integrated with a specialized condenser and receiver system to recover 90% to 95% of solvents for reuse
Key Features
Mechanical Seal Integrity: Equipped with a high-quality double mechanical seal at the vacuum side and a rotary joint at the heating side to prevent leaks.
Lump Breaker (Optional): Internal high-speed choppers/lump breakers can be installed to break up agglomerates during the drying cycle.
Variable Speed Drive: A built-in VFD allows for adjustable rotation speeds to suit different material densities and drying stages.
SIP/CIP Capability: Designed for easy integration with Clean-in-Place (CIP) systems for rapid validation between batches.
Safety Guards: Full SS 304 safety railings with limit switches prevent operation when the area is not secure.
Operational Benefits
Gentle Action: The slow tumbling motion prevents the attrition of delicate granules, maintaining the desired particle size.
Uniformity: Achieving uniform moisture content (LOD) throughout the batch due to continuous macro-mixing.
Energy Efficient: High thermal efficiency due to direct heat transfer from the jacketed walls to the material under vacuum.
