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.
Conical vessel rotates slowly under vacuum to tumble the product.
Jacketed surface provides indirect heat transfer.
Minimal internal parts reduces contamination and simplifies cleaning.
Benefits ✔ Uniform drying with reduced hot spots ✔ Shorter drying time than static dryers ✔ Near-complete discharge with cone shape ✔ Suitable for volatile & toxic materials
Common Options
Integrated solvent condenser & receiver
Vacuum pump system
PLC/fully automated control
🏭 Typical Uses
Drying wet cake after filtration (pharma & chemicals)
