Description
Complete Continuous Counter-Current Extraction Systems | High-Efficiency Automated Extraction Production Lines
💡 The continuous counter-current extraction system employs a counter-current contact extraction process, in which the raw material and solvent flow in opposite directions. It offers high extraction yields and continuous, automated operation, making it suitable for large-scale industrial production of traditional Chinese medicine, plant extracts, food, and health supplements.
I. Product Overview
The continuous counter-current extraction system is a highly efficient extraction production line specifically designed for raw materials used in botanicals, traditional Chinese medicine, food, and health supplements. It employs the counter-current extraction process to achieve continuous counter-current contact between the raw material and the solvent, significantly increasing the yield of active ingredients while reducing raw material waste and energy consumption. The entire system is manufactured from sanitary-grade stainless steel, supports automated continuous production, and is suitable for large-scale industrial production scenarios. It is widely used in the plant extraction, pharmaceutical, and food industries.
II. Key Features
✅ High-efficiency extraction process
Using continuous counter-current extraction technology, the raw material and solvent flow in opposite directions, resulting in more thorough contact. This increases the extraction rate of active ingredients by more than 30%, significantly reduces raw material loss, and improves production efficiency.
✅ Continuous, automated production
The equipment enables continuous feeding and discharging, with fully automated control throughout the entire process. It can operate stably 24 hours a day, is suitable for large-scale industrial production, minimizes manual intervention, and reduces production costs.
✅ Low-energy design
The countercurrent process can significantly reduce solvent usage and steam consumption. When combined with a heat recovery system, energy consumption is reduced by more than 40% compared to traditional extraction processes, enabling green and energy-efficient production.
✅ Sanitary-grade compliant design
The entire system is manufactured from 304/316L stainless steel, with polished inner and outer surfaces that eliminate dead corners and facilitate cleaning. It is compatible with a CIP cleaning system and complies with GMP pharmaceutical standards and food-contact material regulations, making it suitable for compliant production requirements.
✅ Modular Customization Options
The equipment features a modular design, allowing the length of the production line and process parameters to be customized based on raw material characteristics and production scale. It is equipped with systems for extraction, filtration, concentration, and solvent recovery, creating an integrated extraction production line.
✅ Wide range of applications
Suitable for extraction processes involving various plant materials, traditional Chinese medicine decoctions, and food ingredients, this equipment supports multiple extraction methods—including water, alcohol, and oil extraction—making it a versatile solution that meets the production needs of multiple industries.

IV. Explanation of the Process Principles
The core principle of the continuous counter-current extraction system is the counter-current contact between the raw material and the solvent: the raw material is continuously fed into one end of the system, while the solvent flows in the opposite direction from the other end. The two come into contact in opposite directions within the system, causing the active ingredients to continuously dissolve into the solvent. Finally, the waste residue and the extract are discharged separately from both ends of the system. This process enables continuous and highly efficient extraction, significantly improving extraction efficiency while reducing raw material and energy consumption.
