Introduction to Circular Vacuum Dryers

Circular vacuum dryers are critical in the pharmaceutical and chemical industries due to their efficiency in drying heat-sensitive materials. These dryers eliminate moisture under reduced pressure, thereby lowering the boiling point of water and allowing drying at lower temperatures. This process is both energy-efficient and preserves the quality of thermolabile substances.

Working Principle of Circular Vacuum Dryers

The circular vacuum dryer operates by enclosing the material to be dried within a sealed chamber from which air is evacuated. A vacuum pump reduces the pressure inside the drum, typically ranging from 50 to 100 mmHg. The heating mechanism, which can be a jacketed wall or an external heater, maintains the temperature of the substance between 30°C and 80°C, depending on the sensitivity of the material.

Movement within the drum is facilitated by rotating mechanisms that ensure uniform exposure of the material to the low-pressure environment. The moisture evaporates at reduced temperatures and is removed continuously, ensuring efficiency. Condensers are usually attached to collect the vaporized solvents for reuse or safe disposal.

Operational Parameters

Key operational parameters of circular vacuum dryers include:

• Vacuum Level: Maintained between 50 to 100 mmHg.
• Temperature: Typically ranges from 30°C to 80°C, adjustable based on material sensitivity.
• Rotation Speed: Between 5 to 20 RPM to ensure even drying.
• Batch Capacity: Varies from 50 kg to several tons depending on the model size.

Each of these parameters can be adjusted based on the specific requirements of the materials being processed, providing flexibility in application.
