Roto Cone Vacuum Dryer

The Roto Cone Vacuum Dryer (RCVD) is designed for batch drying of pharmaceutical powders, crystalline materials, granules, and other suitable solids under reduced-pressure conditions. It operates using a rotating double-conical vessel that gently tumbles the product while indirect heating and vacuum-assisted evaporation remove moisture or suitable volatile solvents.

Intence Engineering includes Roto Cone Vacuum Dryers in its pharmaceutical drying equipment portfolio. Vacuum drying technology allows materials to be processed at lower evaporation temperatures than conventional atmospheric drying. The rotating vessel promotes material movement and contact with heated surfaces, making this technology suitable for selected heat-sensitive and solvent-containing products.

Applications of Roto Cone Vacuum Dryer

1. Pharmaceutical API Drying: Removing residual moisture or suitable solvents from active pharmaceutical ingredients (APIs) and intermediate materials under controlled vacuum drying conditions.
2. Heat-Sensitive Material Drying: Processing suitable temperature-sensitive pharmaceutical materials at reduced evaporation temperatures to help minimize thermal exposure.
3. Crystalline and Powder Drying: Supporting gentle batch drying of compatible crystalline substances, fine powders, and granular materials through continuous vessel rotation.
4. Solvent Removal and Recovery: Removing suitable volatile solvents from processed materials, with provision for vapor condensation and recovery when the required system is installed.

Key Features

• Vacuum Drying Principle: Reduced pressure lowers the evaporation temperature of moisture and suitable solvents, supporting lower-temperature drying.
• Rotating Double-Cone Design: The double-conical vessel gently tumbles the material to promote exposure to heated surfaces during batch drying.
• Indirect Heating: Heat is transferred through the vessel wall, commonly using a jacketed heating arrangement, without direct contact between the heating medium and product.
• Gentle Material Movement: Low-speed rotation supports drying of suitable powders, crystals, and other materials requiring controlled mechanical handling.
• Enclosed Batch Processing: The sealed drying chamber supports product processing within a contained environment when properly configured.
• Moisture and Solvent Removal: Vacuum-assisted evaporation facilitates the removal of volatile components from suitable processed materials.
• Product Discharge: The double-conical geometry supports material movement toward the discharge opening after the drying cycle.

Available Capacity

Capacity: Based on Selected Vessel Size and Drying Requirements

The appropriate Roto Cone Vacuum Dryer capacity depends on product bulk density, batch loading volume, moisture or solvent content, drying temperature, vacuum conditions, and material characteristics. Vessel dimensions and operating parameters are selected according to the intended application. Specific capacity options for Intence Engineering’s RCVD models should be confirmed with the manufacturer.
