📌 What Is a Rotary Cone Vacuum Dryer (RCVD)
A Rotary Cone Vacuum Dryer is a batch drying system that gently dries heat-sensitive, volatile, or oxidizable materials under vacuum and at low temperatures. It’s widely used in pharmaceutical, chemical, food, and fine chemical industries for drying powders and wet cakes without damaging the product.
Why It’s Useful
Low temperature drying: Vacuum allows moisture evaporation at lower temperatures.
Uniform drying: Conical shape plus rotation ensures even heat transfer.
Gentle on product: Ideal for delicate solids like APIs and chemicals.
Efficient solvent recovery: Integrated vacuum & condenser systems help recover solvents.
