Ethanol solvent extractor

laboratoryfor nicotine

Overview
Industrial-scale nicotine extraction system designed for solvent-based extraction from tobacco leaves, offering automated control, integrated solvent recovery and modular scalability to match production requirements.

Key features

• Efficient solvent-based extraction: Compatible with common solvents (e.g., ethanol, NO6 Solvent) to maximize nicotine recovery.
• High extraction yield: Precise control of temperature, pressure and solvent-to-material ratio for consistent high-purity extracts.
• Advanced process control: PLC-based automation for real-time monitoring and parameter adjustment to reduce manual intervention.
• Modular & scalable design: Configurable modules for small batches to large volumes and expandable to accommodate production growth.
• Integrated solvent recovery: Recovery unit minimizes solvent loss and enables solvent reuse to lower operating costs and environmental impact.
• Stainless steel construction: Food-grade 304 / 316L for inner contact surfaces, ensuring corrosion resistance and hygienic cleaning.
• Energy efficiency: Design features for reduced overall power consumption including energy-recovery options.

Applications

• Nicotine extraction from tobacco leaves for pharmaceutical, vaping and tobacco industries.
• Production of high-purity nicotine for further refinement or formulation into downstream products.

Benefits

• Consistent production of high-purity nicotine suitable for downstream processing.
• Customizable configurations to meet specific plant capacities and process requirements.
• Safety and regulatory support with hygienic design and solvent management features.
• Turnkey delivery options including installation, operator training and after-sales support.

Extraction tank & process highlights

• Multi-function straight-barrel extraction tank with segmented-jacket heating; options for bottom steam and bottom-cover jacket heating to ensure uniform temperature distribution.
• Dynamic circulation with filtered bottom draw and pump-back to the tank top for continuous extraction and improved yields.
• Two-stage or multi-stage condensation and cooling: vertical/horizontal condensers, cooler and oil–water separator to optimize volatile oil and nicotine recovery.
• Two-layer stainless steel filter plate (support plate + laser-cut thin plate) with hinged access for inspection and cleaning.
• Pneumatic roller-type slag discharge door with multi-point locking and safety latch to ensure secure sealing and safe discharge.
• CIP-compatible accessories: automatic rotating spray ball, temperature & pressure gauges, explosion-proof sight glass, quick-opening feed port.
• System components include: extraction tank, defoamer, condenser, cooler, oil–water separator, oil receiver, duplex strainer, pumps and process piping.

Operating principle (summary)

• Components with lower boiling points vaporize first; vapors are condensed and separated into oil and water phases. Reflux or discharge is determined by process parameters. Oil–water separation relies on density differences to collect volatile oil and nicotine fractions.
