Complete Solutions for Traditional Chinese Medicine Extraction | Combined Extraction and Percolation Vessel Process
💡To address the challenges of low extraction efficiency in traditional Chinese medicine, the loss of active ingredients at high temperatures, and poor extraction conversion rates for valuable medicinal materials, we employ a combined extraction and percolation process. This dual-pathway approach—featuring high-efficiency extraction for mass production and low-temperature percolation to preserve bioactivity—balances production capacity with the retention of active ingredients in the medicinal materials.
I. Industry Challenges
Traditional Chinese medicine extraction methods rely on equipment that is limited in variety and lacks versatility; batch decoction often results in incomplete extraction of active ingredients and their decomposition and loss due to high temperatures; When valuable medicinal materials are processed using conventional high-temperature decoction, there is significant loss of active components and low raw material utilization. This limits the efficacy of the final product and hinders production cost control, making it difficult to balance large-scale mass production with the quality requirements of high-end medicinal materials.
II. Solution: A Scientifically Designed Combination of an Extraction Tank and a Percolation Tank
A combination of mass production extraction and low-temperature percolation processes that balances production capacity and medicinal quality
In the herbal medicine extraction process, the scientific combination of extraction tanks and percolation tanks effectively addresses the industry’s pain points of low extraction efficiency and loss of active ingredients. Extraction tanks can precisely control extraction temperature and duration based on the characteristics of the herbal materials, adapting to different raw materials such as roots, stems, flowers, and leaves to achieve efficient extraction of active ingredients; Percolation tanks, on the other hand, are designed for precious herbal materials. They employ a low-temperature, slow-percolation process to maximize the retention of active ingredients and prevent high temperatures from degrading their medicinal value. Working in tandem, these two systems not only meet the efficiency requirements of large-scale production but also ensure the purity and quality of herbal extractions, laying a solid foundation for the production of traditional Chinese medicine formulations.
III. Key Advantages of Individual Equipment
✅ Multifunctional Extraction Vessel: High-efficiency temperature-controlled extraction, suitable for mass production of bulk herbal materials
The temperature, extraction duration, and solvent volume can be flexibly adjusted to accommodate a wide range of bulk Chinese medicinal materials, including roots, rhizomes, vines, wood, flowers, leaves, and whole herbs. The closed-loop reflux extraction process ensures high yield of active ingredients, making it suitable for large-scale, continuous extraction production in industrial settings.
✅ Room-temperature percolation tank: Low-temperature, slow percolation to preserve the bioactivity of valuable medicinal herbs
The entire process is conducted at low temperatures without exposure to high heat; instead, solvents are used to naturally percolate through and infuse the medicinal materials. For precious herbs such as ginseng, cordyceps, and notoginseng, this method prevents the thermal decomposition of heat-sensitive active ingredients, significantly improving the utilization rate of valuable raw materials and the quality of the extract.

V. Practical Application Scenarios
✅ Extraction of Raw Materials for Traditional Chinese Medicines
Bulk herbal materials are decocted on a large scale using extraction kettles, while valuable auxiliary ingredients undergo low-temperature extraction in percolation kettles, ensuring the stability and consistency of the therapeutic effects in traditional Chinese patent medicine formulations.
✅ Further Processing of Traditional Chinese Medicine Herbal Slices
Extraction and processing of active ingredients from herbal slices, with equipment flexibly switched based on the cost of raw materials to improve the quality of the final extract.
✅ Production lines for traditional Chinese medicine health supplements and plant extracts
Standardized production of plant extracts, efficient extraction of raw materials in large batches, and low-temperature preservation of the bioactive properties of valuable, efficacious ingredients—ideal for the production of high-end health supplement ingredients.
VI. Summary of the Proposal’s Value
The combined extraction process, which pairs an extraction tank with a percolation tank, overcomes the limitations of single-unit equipment in terms of versatility. For large-scale production, the extraction tank boosts capacity and controls costs, while the percolation tank preserves the bioactivity and enhances the purity of high-end, valuable raw materials. This approach addresses key challenges—such as the loss of active ingredients during TCM extraction and low raw material utilization—at the source. The entire process complies with TCM GMP extraction standards and is suitable for the production of all categories of products, including decocted herbal slices, proprietary Chinese medicines, and plant extracts.
