Description
Heat-Recirculating Vacuum Extraction and Concentration Unit | Integrated Extraction and Concentration Equipment
💡The thermal reflux vacuum extraction and concentration unit is a compact, integrated system that combines extraction, thermal reflux, and vacuum concentration, It completes the entire process—from raw material extraction to concentrate production—in a single unit. Constructed from 304/316L stainless steel, its low-temperature process preserves active ingredients, making it suitable for production lines of traditional Chinese medicine, botanical extracts, and health foods.
I. Product Overview
The Thermal Reflux Vacuum Extraction and Concentrator is an integrated extraction and concentration system designed specifically for small- and medium-scale production scenarios. It combines extraction, thermal reflux, and vacuum concentration functions into a single unit, enabling the completion of the entire process—from raw material extraction to solution concentration—without the need for additional equipment. Manufactured from sanitary-grade stainless steel, the unit supports low-temperature vacuum extraction and thermal reflux cycles, effectively preserving the active ingredients in raw materials while reducing energy consumption and solvent loss. It is widely used in industries such as traditional Chinese medicine, botanical extracts, health supplements, and food ingredients.
II. Key Features
✅ Integrated extraction and concentration design
A single unit simultaneously performs raw material extraction, hot reflux circulation, and vacuum concentration, eliminating the need for additional concentration equipment, significantly reducing equipment costs and floor space, and meeting the needs of small- and medium-scale production.
✅ Heat-recovery process, highly efficient and energy-saving
This process employs thermal reflux extraction technology, which recycles solvents to reduce solvent loss. At the same time, it utilizes the thermal energy from the steam generated during the extraction process as a heat source for concentration, significantly reducing energy consumption and achieving energy savings of more than 30% compared to traditional processes.
✅ Low-temperature vacuum extraction to preserve bioactivity
It enables vacuum cryogenic extraction, which reduces the oxidation and decomposition of heat-sensitive components, effectively preserves the active substances in the raw materials, and improves product quality and yield.
✅ Manufacturing in Compliance with Sanitary Standards
The main body of the equipment is made of 304/316L stainless steel, with polished inner and outer surfaces that eliminate dead corners and facilitate cleaning. It complies with GMP pharmaceutical standards and food-contact material regulations, making it suitable for compliant production requirements.
✅ Automated control, easy to operate
Equipped with a PLC control system, it enables automatic control and adjustment of parameters such as temperature, pressure, and liquid level, supports one-touch start/stop and fault alarms, reduces the workload of manual operations, and improves production stability.
✅ Wide range of applications
Suitable for water and alcohol extraction processes involving various plant materials, traditional Chinese medicine decoction pieces, and food ingredients, this machine can simultaneously perform extraction and concentration, offering multi-functional capabilities and adaptability to a wide range of production scenarios.

IV. Explanation of the Process Principles
The core principle of the thermal reflux vacuum extraction and concentration unit is an “integrated extraction and concentration cycle”: The raw material comes into contact with the solvent in the extraction tank, and the active ingredients dissolve into the solvent; The extract circulates through the thermal reflux system, utilizing the thermal energy from the vapor generated during the extraction process to undergo vacuum concentration in the concentrator. The vapor from the concentrated solvent is condensed and recovered, then returned to the extraction tank for reuse, thereby achieving closed-loop solvent utilization and efficient thermal energy recovery while simultaneously completing both the extraction and concentration processes.
