Rotary Vacuum Dryer

Rotary Vacuum Dryer / Roto Cone Vacuum Dryer (RCVD) Manufacturers in India

Rotary Vacuum Dryer

Aquaon Engineers is a prominent Rotary Vacuum Dryer (RCVD) machine manufacturers, suppliers, and exporters in Mumbai, India. The Roto Double Cone Vacuum Dryer is a type of industrial dryer that is designed to dry heat-sensitive and easily oxidizable materials under vacuum conditions. The machine includes a turning conical chamber that runs in vacuum, which enables items to be dry at a lower temperature than with normal drying techniques. This creative design keeps the drained material's quality intact while reducing its thermal degradation.

Double cone dryer is a highly efficient industrial drying equipment commonly used in pharmaceuticals, chemicals, food processing, and other industries for drying heat-sensitive materials. The dual-cone design ensures continuous and gentle agitation, minimizing the risk of product degradation or overheating. As the material is heated and rotated within the dryer, moisture evaporates evenly, resulting in a high-quality, consistent product. Ideal for powders, granules, and crystals, double cone dryers are known for their energy efficiency, compact design, and ability to handle a wide range of materials, making them a preferred choice for controlled drying processes.
