Vacuum Dryer Mixer
A vacuum dryer mixer is a sealed horizontal or vertical mixer vessel fitted with a full vacuum system — including a vacuum pump, condenser, vapor trap, and all necessary sealing, instrumentation, and controls.
By pulling a vacuum inside the sealed mixing vessel, atmospheric pressure is dramatically reduced — lowering the boiling point of water and solvents to well below their normal boiling temperatures.
This allows the vessel contents to dry at temperatures far below what atmospheric drying would require, protecting heat-sensitive materials from thermal degradation while simultaneously mixing them to ensure uniform drying throughout the batch.
The ability to mix and dry in one sealed vessel eliminates the need for a separate dryer, reduces product transfer between equipment, minimizes contamination risk, and significantly shortens total processing time.
Solvent recovery systems can be connected to the condenser to capture and recycle valuable solvents.
Best For
- Materials requiring drying after wet granulation — drying in same vessel eliminates transfer
- Heat-sensitive APIs, botanical extracts, nutraceutical actives that degrade at normal drying temperatures
- Solvent-bearing compounds requiring controlled solvent removal and recovery
- Oxygen-sensitive materials requiring inert atmosphere processing
Industries
Pharmaceutical manufacturing (API drying and blending), nutraceuticals (heat-sensitive botanicals), specialty chemical (solvent-bearing compounds), battery materials (oxygen-sensitive electrode powders).
