For process developers working in pharmaceuticals, botanicals, traditional medicines, nutraceuticals and food ingredients, the step from laboratory glassware to reliable pilot-scale equipment is critical.
China Soxhlet Extraction Equipment for Pilot Plant from Nanjing Hjchem Equipment Co.,Ltd is designed precisely for this stage – providing realistic, controllable conditions while keeping the flexibility needed for R&D and scale-up.
Unlike a simple extraction tank, this pilot system combines Soxhlet extraction, multi-functional (dynamic circulation) extraction, vacuum concentration and solvent recovery into one modular stainless-steel package.
Each subsystem can be linked for fully integrated runs or operated independently as a standalone unit, allowing you to simulate different production scenarios on the same skid.
What Is Pilot Plant Soxhlet Extraction Equipment?
Pilot Plant Soxhlet Extraction Equipment from Nanjing Hjchem is the pilot-scale industrialization of that concept:
Constructed in stainless steel instead of glass
Sized for kilogram-level batches, not just grams
Equipped with vacuum, heating, solvent recovery and industrial control
Designed as a self-contained pilot plant, not just a lab bench unit
In practice, this means you can run genuine pilot campaigns – including extraction, concentration and solvent recycling – under conditions that closely match future commercial production, while still enjoying the flexibility required in development and scale-up work.
Soxhlet Extraction Equipment Structure
Integrated Process Concept – By Nanjing Hjchem
The main advantage of Nanjing Hjchem’s Pilot Plant Soxhlet Extraction Equipment is that it combines four key process functions on a single skid.
1. Soxhlet Extraction System
The pilot Soxhlet module translates the classic Soxhlet cycle into stainless-steel hardware:
Solvent is heated in a boiling/extraction vessel until it evaporates
Vapor is condensed and directed into the Soxhlet extraction chamber
Condensed solvent repeatedly percolates through the solid bed
Once the level reaches a set point, extract-rich solvent is automatically siphoned back
This cyclic washing mechanism gives deep extraction with excellent solvent economy and is especially useful when your laboratory development has already been based on Soxhlet methods.
2. Dynamic Circulation (Multi-Functional) Extraction System
Alongside the Soxhlet module, the pilot skid includes a dynamic circulation extraction system:
Solvent is pumped in a loop through the extraction tank and material bed
Flow rate, temperature and extraction time are fully adjustable
The mode is suitable for faster extraction or solid materials that benefit from strong circulation
Because the Soxhlet extraction system and dynamic circulation extraction system can be freely combined or run separately, you can:
Compare Soxhlet vs dynamic extraction performance on the same equipment
Use rapid dynamic extraction for screening work
Apply Soxhlet mode when you need deeper extraction or closer alignment to pharmacopeia methods
This flexibility makes the pilot unit a powerful tool for both R&D and process optimization.
3. Vacuum Reduced-Pressure Concentration System
After extraction, the liquid extract is usually too dilute for direct use. The integrated vacuum concentration system allows you to:
Transfer extract-rich solvent into a dedicated concentration vessel
Apply reduced pressure so the solvent boils at a lower temperature
Concentrate the extract without excessive thermal stress
Because concentration is part of the same skid, you can complete the whole sequence – extraction → concentration → solvent recovery – without moving the liquid to external equipment, which improves data quality and simplifies pilot campaigns.
4. Solvent Recovery System
Solvent consumption and environmental performance are important considerations from the pilot stage onward. The integrated solvent recovery system:
Condenses vapors generated in extraction and concentration
Returns solvent to storage or directly back to the process
Reduces operating cost and solvent emissions
Together, these four subsystems turn the China Soxhlet Extraction Equipment for Pilot Plant into a closed-loop mini-plant, not just a single extraction pot.

Frequently Asked Questions (FAQ)
1.How does this pilot plant equipment differ from a standard lab Soxhlet extractor?
A lab Soxhlet is made of glass and suitable only for gram-scale testing. The China Soxhlet Extraction Equipment for Pilot Plant from Nanjing Hjchem is built in stainless steel, handles kilogram-level batches, integrates dynamic extraction, vacuum concentration and solvent recovery, and includes industrial-grade controls.
2.Can I test both traditional decoction and Soxhlet-style extraction on the same skid?
Yes. Using the dynamic circulation extraction subsystem, you can simulate decoction-like conditions; using the Soxhlet subsystem, you can perform cyclic washing. Both modes are available on the same pilot skid, and can be combined or used independently.
3. Is this equipment suitable for ethanol-based extractions under explosion-proof requirements?
The system can be configured with appropriate materials, seals, and explosion-proof electrical components when working with ethanol or other flammable solvents. Explosion-proof versions of motors, instruments and HMI cabinets can be supplied according to your safety classification.
4. How does the pilot equipment help in scaling up to a commercial plant?
Because the pilot skid integrates the same key steps – extraction, vacuum concentration and solvent recovery – as an industrial line, you can determine realistic temperatures, vacuum levels, cycle times and solvent ratios. These parameters form a solid basis for designing larger commercial Soxhlet systems and related solid–liquid extraction equipment.
5. What kind of documentation and support can Nanjing Hjchem provide for this pilot system?
We typically provide basic mechanical drawings, process flow diagrams, utility requirement lists and operation manuals. Depending on your project, we can also support FAT inspections, remote start-up guidance and coordination with your engineering team to integrate the pilot skid into your existing pilot plant.
