The GUNT Solid-Liquid Extraction Unit enables the extraction of soluble components from a solid mixture using a revolving extractor. It supports multiple continuous stages and discontinuous operation for flexible experimentation.
Product Features
- Solvent (distilled water) delivered to sprinklers in up to three continuous extraction stages
- Solvent seeps through solid extraction material absorbing soluble components (potassium hydrogen carbonate)
- Enriched solvent is collected and passed to subsequent stages
- Extraction material continuously fed by spiral conveyor, moving countercurrent to solvent flow
- Extraction residue drops into tank after one revolution of the extractor
- Valves allow switching between 1-, 2-, or 3-stage continuous modes
- Discontinuous mode available by stopping extractor rotation
- Three pumps with individually adjustable speeds deliver solvent to each stage
- PID controllers adjust solvent temperature for each stage
- Conductivity sensors on each stage monitor the extraction process
- All measured values can be viewed and analyzed via software
- Extraction material prepared by soaking granular aluminium oxide in potassium hydrogen carbonate solution, then drying
Benefits
- Demonstrates countercurrent extraction with multiple operational modes
- Provides precise control over solvent flow and temperature for optimized extraction
- Monitors extraction progress in real-time with conductivity sensors
- Ideal for education and training in chemical engineering and separation techniques
