Vacuum Low-Temperature Liquid Extraction & Concentration Unit

Integrated 3-in-1 System | Pharmaceutical Grade 304/316 SS | Precision Pilot Scale


This specialized liquid extraction equipment is engineered specifically to protect the bioactive integrity of sensitive compounds. Unlike traditional high-temperature decoction methods that may degrade pharmaceutical efficacy, this system utilizes high-vacuum technology to create a vacuum evaporator environment. By enabling boiling at low temperatures (70°C – 100°C), the unit integrates boiling, low-temperature extraction, and liquid concentration into a single, user-friendly system. It is the premier choice for university research, TCM hospitals, and customized herbal paste centers requiring rigorous potency standards.

Core Value Propositions


  • Protection of Active Compounds: Boiling points are controllable at 70°C-100°C for water extraction and 70°C-80°C for alcohol extraction, effectively locking in biological activity and preventing efficacy loss.
  • Negative Pressure Vacuum Process: Leverages a high-performance vacuum pump to create a negative pressure environment, achieving “low pressure, low boiling point, and high efficiency” during the liquid extraction equipment operation.
  • Precision Temperature Control: The boiling point can be precisely set within the 70°C-100°C range based on specific material characteristics to meet exact pharmacological requirements.
  • Compact Integrated Structure: Combines boiling, extraction, concentration, and condensation recovery into a systematic evaporator system, minimizing material transfer loss.
  • Flexible Customization: Available in various pilot-scale specifications (50L-100L) with deep customization options for facility space and specific production capacities.

Primary Application Scenarios


Scientific Research & Pharmacological Studies

Used by medical colleges to research extraction rates and material physical properties, providing a stable low-temperature evaporator system for reliable experimental data.

High-End Customized Herbal Pastes

Ideal for hospital pharmacies and clinics to produce premium-quality herbal pastes and powders, preserving the original color and aroma of the raw materials.

Small-Batch Production of Thermosensitive Drugs

Enables pharmaceutical companies to develop new products or produce high-value drugs that are prone to thermal decomposition, offering high-gradient liquid concentration for flexible production.

Solutions to Critical Technical Challenges


  1. Preventing Potency Loss: Traditional boiling often deactivates enzymes and volatile oils; this vacuum evaporator completes extraction at low temperatures to ensure component stability.
  2. Enhancing Extraction Efficiency: Vigorous boiling under negative pressure creates a natural stirring effect, accelerating solute exchange and outperforming static extraction methods.
  3. Simplifying Complex Operations: The integrated design allows for precise boiling point adjustments, bridging the gap between independent boiling and concentration stages.
  4. Optimizing Limited Lab Space: Designed with a compact footprint to meet the requirements of small-scale, high-performance production in tight laboratory environments.
  5. Ensuring Hygiene & Compliance: The fully enclosed negative pressure system prevents component evaporation and external contamination, fully complying with food and drug hygiene standards.

Operating Principle


The unit achieves low-temperature processing through scientific vacuum pressure management:

  1. Feeding & Heating: Crushed raw materials and solvents are added to the tank and heated gently via a thermal oil jacket.
  2. Negative Pressure Boiling: The vacuum pump creates a negative pressure environment where the liquid begins to boil at approximately 70°C, accelerating the dissolution of active ingredients.
  3. Cyclic Concentration: The extract enters the evaporator system. Under vacuum, the secondary steam is condensed and returned through a reflux pipe, achieving rapid dehydration while maintaining pressure balance to produce high-density fluid extracts (specific gravity 1.1-1.25).
