Vertical Ribbon Vacuum Dryer
Specification
Description
A Supradry Vertical Ribbon Vacuum Dryer is a specialized vertical vacuum drying system designed for gentle and efficient drying of powders, pastes, or wet cakes, especially in industries like pharmaceuticals, chemicals, nutraceuticals, and food.
What Is It?
The Supradry Vertical Ribbon Vacuum Dryer is a vertical cylindrical vessel equipped with a helical ribbon agitator that rotates around a central shaft. It operates under vacuum and applies indirect heat (via jacketed walls) to dry sensitive materials efficiently and uniformly.
| Component | Function |
| Vertical cylindrical chamber | Holds the material to be dried. |
| Ribbon agitator | Helical ribbons on a central shaft rotate to move material both upward and downward for uniform drying. |
| Vacuum system | Lowers the boiling point of moisture or solvents to enable drying at lower temperatures. |
| Jacketed wall | Heated using steam, hot water, or thermal oil to provide even heat transfer. |
| Bottom discharge valve | Allows for clean, easy removal of the dried material. |
| Sanitary construction (Supadry) | cGMP-compliant, polished surfaces, and CIP/SIP-ready for sterile applications. |
- Charging: Wet material (paste, cake, or slurry) is loaded into the vertical chamber.
- Vacuum and Heating: Vacuum is applied, and the jacket heats the chamber to evaporate moisture at low temperatures.
- Mixing: The ribbon agitator rotates to continuously mix the material, exposing new wet surfaces and ensuring uniform drying without degradation.
- Solvent Recovery: Evaporated vapors are collected and condensed.
- Discharging: Dried product is discharged from the bottom, often without the need for manual handling.
- Vertical space-saving design – smaller footprint than horizontal dryers.
- Uniform drying – dual-directional ribbon mixing ensures all material is evenly exposed to heat.
- Low-temperature operation – ideal for thermosensitive
- Gentle mixing – suitable for fragile crystals or powders.
- Fully enclosed & sanitary – complies with FDA and cGMP standards.
- Efficient solvent recovery – important for cost and environmental safety.
- Pharmaceutical ingredients (e.g., APIs)
- Herbal extracts and nutraceuticals
- Fine and specialty chemicals
- Food additives and flavors
- Biotech intermediates
