A Rotocone Vacuum Dryer (RCVD) is a specialized drying system used for drying heat-sensitive, delicate, or volatile materials. It operates under vacuum conditions, which allows drying at lower temperatures, making it ideal for materials that cannot withstand high heat. The system combines
rotary motion and vacuum technology to ensure efficient and uniform drying

How It Works:

1. Material Loading: The wet material is loaded into the conical-shaped vessel.
2. Vacuum Creation: A vacuum is applied to lower the boiling point of moisture, enabling drying at lower temperatures.
3. Heating: Heat is supplied through the jacketed cone, warming the material indirectly.
4. Rotary Motion: The cone rotates slowly, tumbling the material for even heat distribution and drying.
5. Moisture Evaporation: The vacuum removes moisture and volatile solvents, which are collected through a condenser.
6. Discharge: The dried material is discharged through a valve for further use.

Key Features and Benefits:

• Low-Temperature Drying: Protects heat-sensitive materials from degradation.
• Uniform Drying: Rotary motion ensures even drying and prevents clumping.
• Solvent Recovery: Volatile solvents can be recovered during the drying process.
• Dust-Free Operation: The closed system prevents contamination and exposure.
• Energy Efficient: Vacuum drying reduces energy consumption compared to conventional methods.
• Compact Design: Saves space and integrates multiple functions into one system.

Applications:

• Pharmaceuticals: Drying active ingredients and intermediates.
• Chemicals: Processing specialty chemicals, pigments, and dyes.
• Food Industry: Drying food additives and ingredients.
• Waste Management: Drying sludge and other waste materials. RCVD is available in sizes ranging from 100 to 10,000 liters, with optional condensers and receivers based on client needs.
