Rotary Cone Vacuum Dryer (RCVD)
Gentle, Contamination-Free Drying for Heat-Sensitive Materials
At Liuminex, we design and manufacture high-quality Rotary Cone Vacuum Dryers (RCVDs) for the efficient drying of heat-sensitive, hygroscopic, and oxygen-sensitive materials under vacuum. Our RCVDs ensure uniform drying, minimal degradation, and maximum recovery of active ingredients, making them ideal for the pharmaceutical, chemical, food, and fine chemical industries.
Suitable for Drying
- APIs and fine chemicals
- Agrochemicals and pesticides
- Intermediates and bulk drugs
- Thermally sensitive powders
- Crystalline materials
- Pigments, dyes, and colorants
- Nutraceuticals and herbal extracts
Key Features
- Double-cone rotating shell for uniform drying
- Vacuum operation minimizes thermal degradation
- Efficient solvent recovery via condenser & receiver system
- Internal baffles or lump breakers (optional) for better mixing
- Clean-in-Place (CIP) and flameproof options available
- Dust-tight and contamination-free design
- cGMP & FDA-compliant construction for pharma-grade use
