Description
Single-Effect External-Circulation Vacuum Concentrator | Vertical Low-Temperature Extraction Liquid Concentration Equipment for Small- and Medium-Sized Production Lines
💡 The single-effect external-circulation vacuum concentrator is a low-temperature concentration device specifically designed for small- and medium-sized production lines in the pharmaceutical, herbal extraction, and food industries. It features a vertical external-circulation natural heat exchange structure and operates at low temperatures under negative pressure. enabling rapid feed circulation and short residence times, which minimizes scaling and coking. This ensures the complete retention of active ingredients in heat-sensitive materials and is suitable for concentrating various types of feed solutions, including extracts, alcohol-precipitated solutions, and clear pastes.
I. Product Overview
The single-effect external-circulation vacuum concentrator features a vertical external-circulation system as its core structure and incorporates vacuum and low-temperature technology to achieve highly efficient concentration of feed solutions. The equipment operates stably and is easy to operate. It provides uniform heating and a short residence time for the feed solution, making it resistant to coking and scaling. It also complies with GMP production requirements and is suitable for use in small- to medium-sized production lines across various industries, including pharmaceuticals, herbal extracts, and food.
II. Structural Configuration Description
The main unit consists of a heating chamber, an evaporation and separation chamber, a condenser, a condensate collection tank, a vacuum system, piping, valves, and other components. The entire unit features a vertical, external-circulation, integrated sanitary design:
✅ Vertical natural external circulation heat exchange structure
The feed solution circulates automatically between the heating chamber and the separation chamber due to the temperature difference, ensuring uniform heating throughout the system. This eliminates the need for a high-power circulation pump, resulting in lower operating energy consumption.
✅ High-Efficiency Gas-Liquid Separation Unit
The separation chamber is equipped with a built-in multi-stage demisting structure that prevents material carryover in the feed liquid, resulting in a significant increase in the recovery rates of ethanol and extract.
✅ Fully sanitary-grade housing, supports CIP (Clean-in-Place) cleaning
The entire unit is mirror-polished with no blind spots, features quick-connect fittings for piping, and is compatible with a fully automatic CIP cleaning system, making cleaning and maintenance simple.
✅ Expandable automated optional modules
Mixing devices, automatic defoaming components, and automatic liquid level and temperature interlock control systems can be installed as needed to enable semi-automatic continuous production.
III. Key Features
✅ High-speed heat exchange via an external circulation system, resulting in high evaporation efficiency
The feed solution circulates at a high flow rate, ensuring thorough heat transfer and high evaporation rates per unit time, making it suitable for concentrating a variety of materials, including extract solutions, alcohol-precipitated solutions, and thick pastes.
✅ Gentle evaporation under vacuum at low temperatures preserves the activity of the material
The entire process is conducted under negative pressure and at low temperatures to prevent the thermal decomposition and oxidative degradation of heat-sensitive components in traditional Chinese medicine, fruit juices, and biopharmaceuticals, thereby ensuring the quality of the final product.
✅ Short-residence-time cycle, resistant to scaling and coking
There is no prolonged localized stagnation of the process fluid, so material is less likely to accumulate on the pipe walls, which significantly reduces the frequency of cleaning and makes routine maintenance convenient and effortless.
✅ Sanitary-grade stainless steel, GMP-compliant manufacturing
Constructed entirely of 304/316L stainless steel, with a mirror-polished finish inside and out to eliminate any hygiene dead zones, it fully complies with production standards for pharmaceutical and food cleanrooms.
✅ Easy to use, with both intermittent and continuous modes
The equipment operates smoothly and is easy to operate, making it suitable for both small-batch batch experiments and small- to medium-scale continuous production.
✅ Compact footprint and low energy consumption
With its compact vertical design, it takes up minimal floor space in the factory and consumes less energy for heat exchange, making it ideal for small- and medium-sized production lines with limited budgets.
IV. Scope of Application
Widely used in the pharmaceutical, herbal extraction, food, and health supplement industries, this equipment is designed to perform low-temperature vacuum concentration on aqueous solutions, alcohol-precipitated extracts, raw fermentation broths, and clear decoctions of traditional Chinese medicine.
