About Vacuum Dryers

ROTOCONE VACUUM DRYER (RCVD)

Product Description

The Rotocone Vacuum Dryer (RCVD) is an industrial drying machine designed for efficient and uniform drying of heat-sensitive materials, powders, granules and crystalline products under vacuum conditions. It is widely used in pharmaceutical, chemical, food and specialty chemical industries where controlled drying and low-temperature processing are required.

The dryer consists of a double-conical rotating vessel that operates under vacuum. The material is gently tumbled inside the rotating vessel while heat is supplied through a suitable heating arrangement. Vacuum reduces the boiling point of moisture or solvents, allowing drying at comparatively lower temperatures. This helps protect heat-sensitive materials and supports uniform moisture removal.

Manufactured with robust construction and hygienic product-contact surfaces, the Rotocone Vacuum Dryer is suitable for batch processing and can be customized according to material characteristics, batch capacity and process requirements.

Key Features

• Double-cone rotating vessel for gentle material mixing and drying.

• Vacuum operation for low-temperature drying.

• Uniform heat transfer through the heating arrangement.

• Suitable for powders, granules and crystalline materials.

• Reduced product degradation for heat-sensitive materials.

• Closed-system processing to minimize contamination and material loss.

• Efficient moisture and solvent removal.

• SS 304 / SS 316 product-contact construction options.

• Vacuum system with condenser and receiver arrangement.

• Easy cleaning, operation and maintenance.

• Customized batch capacity and automation options.

Working Principle

1. Material Loading: The material is charged into the double-conical vessel through the charging opening.

2. Vacuum Creation: The vessel is sealed and connected to a vacuum system to reduce internal pressure.

3. Heating: Heat is supplied through the jacket or other specified heating arrangement.

4. Rotational Mixing: The vessel rotates slowly, continuously tumbling the material and exposing fresh surfaces for effective drying.

5. Moisture Removal: Moisture or solvent evaporates under vacuum and is carried through the vapour line to the condenser.

6. Condensation: Vapours are condensed and collected in a receiver, where applicable.

7. Drying Completion: Drying continues until the required moisture content or process endpoint is achieved.

8. Product Discharge: The dried material is discharged through the designated outlet into a suitable collection container.
