Abstract
The extraction and concentration equipment is a core industrial device that integrates physical and chemical processes. Its technological core lies in the efficient separation and concentration of target components through mechanisms such as evaporation, condensation, and extraction. The equipment typically adopts an integrated double-effect design, leveraging the thermal energy from secondary steam to achieve continuous operation. For example, in traditional Chinese medicine extraction, after medicinal materials are heated with water or alcohol solvents, the extract is concentrated using vacuum low-temperature technology, keeping the temperature below 80°C. This approach not only preserves the activity of heat-sensitive components but also boosts concentration efficiency by more than 40%. Moreover, dynamic circulation extraction technology further enhances process performance by enabling countercurrent contact between the solvent and medicinal materials, thereby creating a high-concentration gradient. As a result, the extraction yield of active ingredients from plants such as ginkgo leaves and ginseng is improved by 10% to 15% compared to conventional methods, while solvent consumption is reduced by 30%.
In practical applications, this technology has been deeply integrated into multiple fields. In the biopharmaceutical industry, it is used to prepare antibiotic extracts with a recovery rate ranging from 1.2 to 1.34 g/cm³. In the food and beverage sector, membrane separation and concentration technologies enable the retention of over 90% of flavor compounds in fruit juices, while consuming only one-fifth of the energy required by conventional evaporation methods. In the environmental protection field, equipment powered by this technology efficiently treats high-salinity wastewater, helping achieve zero-discharge goals. The equipment is typically made of SUS304 stainless steel, meeting GMP standards, and its modular design allows it to accommodate both small-scale laboratory trials of 50 L and large-scale industrial production capacities up to 200 L. A new unit developed in 2025 incorporates a heat pump-based waste heat recovery system, boosting overall energy efficiency by 40%, marking a continuous evolution of extraction and concentration technologies toward greener and lower-carbon practices.
