Chinese Medicine Concentrator

The TCM concentrator is suitable for various processes in industries such as traditional Chinese medicine, botanical extraction, biopharmaceuticals, food, and chemical engineering. These include atmospheric pressure, slight pressure, water decoction, warm immersion, thermal reflux forced circulation, percolation, extraction and concentration of plant essential oils/aromatic oil components, as well as recovery and concentration of organic solvents. It is ideally suited for R&D departments in universities, research institutes, and enterprise laboratories, as well as pilot production in small-to-medium pharmaceutical factories.

• Constructed from high-quality SUS304 stainless steel with mirror polishing, ensuring aesthetic appeal and corrosion resistance.
• Designed for high integration of components, minimal floor space, simple operation, and high efficiency.

1. High Equipment Efficiency
   The small-scale vacuum decompression thermal reflux dynamic extraction-concentration unit optimizes the structure based on original single-cone and inclined-cone models, integrating a small concentrator independently. This enables one-step completion of extraction, concentration, condensation, and filtration, saving raw materials and working time. Efficiency is 20%–35% higher than general multi-functional extraction equipment.
2. High Raw Material Conversion Rate
   During extraction, hot solvents (water or alcohol) continuously flow over raw medicinal materials, dissolving active components from top to bottom through the herb layer. This increases active ingredient content in the original liquid by over 100% compared to ordinary extraction. The unit supports vacuum extraction to reduce loss of heat-sensitive components. Additionally, a frame-type agitator ensures large-volume herbs fully contact the solvent, accelerating active ingredient release.
3. Enhanced Extraction-Concentration Efficiency
   After one-time feeding, the original liquid circulates in a closed system, continuously extracting active components. This saves over 30% solvent compared to the same extraction volume. Steam in the concentrator is reused, reducing energy consumption by ~50%. The evaporation chamber operates at low temperatures, maximizing retention of heat-sensitive components and ensuring optimal concentration results.
4. Flexible Operation Mode
   The extraction and concentration systems can operate independently or in 联动 (linkage). The extraction section features large-diameter manholes/handholes for easy residue removal, and pipelines include filtration for secondary liquid purification, preventing fine residues from entering the concentrator.
5. Superior Thermal Efficiency
   Equipped with a small superheated water generator, it supplies high-temperature steam-water mixtures for all heating needs. This enables rapid heating/cooling with high thermal efficiency—heating power is only ~50% of heat-conducting oil systems. Temperature control is sensitive (±1°C precision), responding quickly to operational commands and avoiding the slow natural cooling of heat-conducting oil systems.
6. Integrated Functional Design

• Oil-water separator and high-efficiency condenser for extracting plant essential oils (e.g., aromatic oils).
• Digital temperature display, online monitoring, and illuminated sight glasses on extraction/concentration tanks for process observation.
• Dedicated pipelines/valves between the extraction tank and vacuum concentrator enable continuous concentration without manual material transfer.
• The concentrator’s sampling valve allows real-time concentration inspection.

7. Compact & Environmentally Friendly
   The unit features a compact footprint, excellent environmental performance (no pollution, odor, or steam leakage), and fully enclosed design compliant with GMP standards.
8. Comprehensive Safety Features
   Equipped with over-temperature alarms, minimum water level control, and steam pressure relief valves to ensure operational safety.

1. Material Loading & Solvent Addition
   Feed medicinal herbs into the extraction tank and add 5–10 times the solvent (water, ethanol, methanol, acetone, etc., as per process requirements).
2. Extraction Heating Phase
   Activate the extraction tank’s heating system, bringing the extraction liquid to a boil. After 20–30 minutes, use a suction filter tube to transfer 1/3 of the extraction liquid to the concentration tank.
3. Concentration Operation

• Close the direct and jacket hot water systems of the extraction tank.
• Activate the direct and heating systems of the concentration tank, maintaining the concentrate temperature at ~80°C and vacuum degree at -0.05 to -0.09 MPa.
• Secondary steam generated during concentration is condensed by the condenser and cooler, returning to the extraction tank as fresh solvent. This fresh solvent flows downward through the herb layer to the bottom of the extraction tank, dissolving soluble components from the herbs.

4. Circulative Extraction-Concentration Loop

• The extraction liquid is suctioned into the concentration tank via the filter tube.
• Secondary steam from concentration is reused as fresh solvent in the extraction tank, forming a closed-loop extraction system until components are fully dissolved (extraction liquid turns colorless).
• Concentration continues until the medicinal paste reaches the required specific gravity. The colorless liquid in the extraction tank can be reused for the next batch.

5. Organic Solvent Recovery (If Applicable)
   For organic solvent extraction:

• Add an appropriate amount of water.
• Activate direct and jacket hot water systems to recover the solvent.
• Discharge the residue after solvent recovery is complete.

• Vacuum degree (-0.05 to -0.09 MPa) reduces boiling points, preserving heat-sensitive components.
• Secondary steam recycling minimizes solvent consumption and energy use.
• The closed-loop design ensures continuous extraction efficiency while complying with GMP standards for hygiene and process control.
