Vacuum Herbal Extraction & Essential Oil Distillation Unit

Integrated Heat Reflux Technology | Multi-Functional Pilot Platform | 304/316L Stainless Steel


This unit is an all-in-one pilot platform engineered specifically for research institutions, universities, and pharmaceutical laboratories. Featuring a compact and precision-machined structure, this herbal extraction equipment integrates three core functions: extraction, concentration, and solvent recovery. The system operates in a fully integrated mode, equipped with an onboard vacuum pump, liquid pump, and control cabinet. It supports water decoction, alcohol extraction, and volatile oil recovery, making it the ideal tool for developing new formulas and the small-batch extraction of medicinal plants.

Core Value Propositions


  • Versatile Process Integration: Features a specialized vacuum converter to switch effortlessly between atmospheric and negative pressure protocols. Supports both “ambient temperature” and “low-temperature” extraction/concentration.
  • Energy-Saving Heat Reflux: Utilizes a “Fresh Solvent Large Reflux” process. By continuously spraying fresh condensate back into the material, the system maintains a high concentration gradient, shortening extraction times by 30-50%.
  • Plug-and-Play Lab Design: A compact, skid-mounted unit with a small footprint. Arrives fully equipped with accessories; simply connect to water and power/steam to begin production immediately.
  • Precision Volatile Oil Recovery: Outfitted with a patent-grade glass oil-water separator. This dual-purpose unit allows for clear, intuitive observation and high-efficiency collection of delicate essential oils.

Primary Application Scenarios


R&D and Academic Instruction: The premier choice for universities and research institutes exploring natural medicine formulas and preparing high-purity samples.

Refining of High-Value Medicines: Optimized for precious botanicals like Ginseng and Cordyceps, maximizing active ingredient retention while minimizing loss.

Fresh Plant & Cosmetic Processing: Uses low-temperature technology to process fresh flowers and leaves, locking in original biological activity and fragrance for essential oils and premium cosmetics.

Hospital Pharmacies & Boutique Production: Ideal for hospital preparation rooms and small plants requiring standardized batch processing for specialized herbal formulas and pastes.

Solutions to Critical Technical Challenges


  • Eliminating Incomplete Leaching: Maintains a constant concentration gradient through dynamic solvent reflux, forcing the high-speed dissolution of active compounds where static tanks often reach saturation.
  • Protecting Thermosensitive Actives: Negative pressure lowers the boiling point, preventing the thermal degradation, deactivation, or discoloration caused by traditional high-temperature boiling.
  • Space & Installation Optimization: Solves the challenge of complex laboratory setups by integrating the extraction vessel, concentrator, and all necessary pumps into a single, mobile framework.
  • Reducing Operational Overhead: The closed-loop system automatically recovers and reuses solvents like ethanol, drastically lowering raw material purchasing and waste disposal costs.

Frequently Asked Questions


Answer: Absolutely. We specialize in providing tailored solutions. Depending on your material characteristics (such as viscosity, acidity, or heat sensitivity) and your facility’s requirements, we can customize the material grade (SS304 or SS316L), heating methods, mixing speeds, and vacuum levels to ensure optimal performance.

Answer: Quality is our top priority. Our equipment is manufactured in strict accordance with GMP and ISO standards. Before shipment, every unit undergoes rigorous testing, including hydraulic pressure tests, vacuum retention tests, and operational trials. We provide complete inspection reports and factory acceptance videos for your peace of mind.

Answer: We offer flexible heating configurations to suit your local energy resources:

Gas Heating: Ideal for facilities where gas is the most cost-effective energy source.

Electric Heating: Equipped with high-efficiency heating elements and precise temperature control.

Steam Heating: Designed with a high-pressure jacket for connection to an external boiler.

Answer: Yes. Each machine comes with a comprehensive English Operation Manual and step-by-step installation videos. We also offer remote technical support via video calls. For large-scale production lines, we can arrange for professional engineers to assist with on-site commissioning and staff training.

Answer: * Lead Time: Standard models are typically ready within 15–20 business days. For complex custom projects, the timeline is finalized during the quoting stage.

Packaging: To ensure safe transit, we use heavy-duty, fumigation-free wooden cases that meet international shipping regulations, providing maximum protection against impact and moisture during sea or air freight.
