The falling-film evaporator utilizes a falling-film evaporation process, which features a short heating time and gentle evaporation. It is particularly suitable for concentrating heat-sensitive materials such as traditional Chinese medicine and plant extracts, and is energy-efficient, highly effective, and resistant to coking.
Description
Vacuum Concentrator | General-Purpose Low-Temperature Concentration and Paste Extraction Equipment for Traditional Chinese Medicine and Food Products with Solvent Recovery
💡 The vacuum concentration system is suitable for processing materials and liquids across a wide range of industries, including traditional Chinese medicine, food, essential oils, and chemicals. It can perform low-temperature concentration, extraction of high-density extracts, and recovery of alcohol and organic solvents. The entire unit is constructed from 304/316 food-grade stainless steel. The low-temperature vacuum process fully preserves heat-sensitive active ingredients and complies with GMP production standards, covering all production scenarios from laboratory-scale pilot testing to pilot-scale and full-scale mass production.
I. Product Overview
The vacuum concentration unit employs a dual-core principle combining vacuum negative pressure and jacket heating to achieve rapid, low-temperature concentration of feed liquids. The equipment integrates concentration, gas-liquid separation, condensation and heat exchange, and solvent recovery functions into a single unit, eliminating the need for additional auxiliary equipment. Compared to traditional high-temperature, atmospheric-pressure concentration equipment, it offers advantages such as lower operating temperatures, higher evaporation efficiency, complete retention of active ingredients, and lower overall energy consumption. It is suitable for continuous production across multiple industries, including pharmaceuticals, food, plant extraction, and fine chemicals.
II. Core Strengths
✅ Vacuum low-temperature evaporation effectively protects heat-sensitive materials
By maintaining a stable vacuum of -0.06 to -0.08 MPa, the material evaporates gently at 55–70°C, preventing the high-temperature decomposition and oxidative loss of heat-sensitive components, and increasing the yield of the final extract by 10–151 TP3T.
✅ Manufactured as a complete unit to sanitary standards, meeting GMP compliance requirements
304/316L stainless steel tank body, with mirror-polished interior and exterior surfaces to eliminate hygiene dead zones; corrosion-resistant and easy to clean and disinfect, fully compliant with clean production standards in the pharmaceutical and food industries.
✅ Multifunctional all-in-one device, supporting multiple processes with a single machine
This system simultaneously performs four key processes—concentration of feedstock, thickening and collection of paste, organic solvent recovery, and solvent reflux extraction—thereby reducing the cost of purchasing multiple pieces of equipment and significantly minimizing the floor space required.
✅ High evaporation efficiency; suitable for a wide range of complex materials
With an optimized heat exchange design, the concentration efficiency has been improved by 30–50% compared to older atmospheric-pressure equipment, and the system is compatible with a wide range of complex feed solutions, including those that are highly viscous, prone to foaming, or prone to crystallization.
✅ Non-stick surface design; easy to use and learn
An optional servo-driven scraper-wall agitator prevents high-viscosity materials from sticking to the walls and caking; the independent electrical control cabinet supports both manual and automatic operating modes, allowing operators to run the equipment independently after just a brief training session.
III. Equipment Structure and Components
The entire machine features a modular design that integrates five core components, along with a vacuum system. The piping layout is simple and orderly, making disassembly, cleaning, and maintenance easy:
✅ Concentrator Tank Body
The jacket-heated tank provides a stable and uniform heat source and can be equipped with an optional wall-scraping agitator for handling high-viscosity materials.
✅ Gas-Liquid Separator
A multi-stage demisting and separation structure blocks carryover of the feed liquid, prevents material loss, and improves solvent recovery rates.
✅ Shell-and-tube condenser
Large-area heat exchange tube bundles rapidly condense secondary steam, resulting in high cooling efficiency.
✅ Coil-type cooler
Deep-cooling recovers the solvent and ensures that the condensate is stored at a low temperature.
✅ Liquid/Solvent Recovery Tank + Vacuum Unit
The concentrated product is collected and the solvent is recovered, while the vacuum pump continuously maintains a stable negative-pressure evaporation environment inside the tank.
IV. Operating Principle
The raw material solution is automatically drawn into the concentration tank via vacuum suction. A heat source is introduced through the jacket to uniformly heat the material, while a vacuum pump continuously extracts air from the tank to maintain a stable negative pressure environment, allowing the solution to boil and evaporate at a low temperature of 55–70°C; The resulting secondary steam sequentially undergoes vapor-liquid separation, tube-bundle condensation, and coil-type deep cooling. The concentrated product is ultimately stored in the finished product tank, while the condensed organic solvent flows into the recovery tank for recovery. The entire process operates in an automated, closed-loop system.
V. Typical Application Scenarios
✅ Pharmaceutical Industry
Low-temperature concentration and purification of traditional Chinese medicine extracts, traditional Chinese medicine concentrates, oral solutions, and biopharmaceuticals.
