In the synthesis and purification processes of pharmaceutical intermediates, manufacturers generally face three major technical challenges: difficulty in breaking emulsified layers, resulting in slow phase separation; significant evaporation of organic solvents, causing environmental and cost pressures; and degradation or loss of activity of heat-sensitive components during prolonged contact time.
Although traditional mixer-setters feature a simple structure, they suffer from low separation efficiency and severe entrainment, often leading to unstable final product yields, excessive residual solvents, and even deterioration of subsequent crystallization quality.
To address these common industry challenges, Zhengzhou Tiei Extraction Technology Co., Ltd. has independently developed the CWL-M Series Centrifugal Extractor. With its unique structural design and innovative materials, the equipment provides an efficient, safe, and scalable industrial solution for extraction, scrubbing, and stripping processes of pharmaceutical intermediates.
Core Technology: Top-Suspended Single-Pivot Structure, Eliminating Leakage Risks at the Source
The CWL-M centrifugal extractor adopts a top-suspended single-pivot bearing design, with no bottom mechanical seal or sliding bearing in the entire unit. This breakthrough structure avoids leakage of process media caused by bottom bearing wear in traditional equipment while significantly reducing maintenance frequency.
For pharmaceutical-grade applications, this means a lower risk of cross-contamination and a more stable continuous operation cycle.
Material Innovation: Fully Fluorinated Polymer Materials Ensuring Zero Metal Ion Leaching
All key components in contact with process materials are made of high-purity fully fluorinated polymer composite materials (such as PTFE and PFA), which can withstand long-term exposure to strong acids, strong alkalis, and various organic solvents.
More importantly, these materials completely prevent the migration of metal ions (such as iron, copper, and nickel) into the process materials, ensuring the chemical purity of intermediates and the safety of final pharmaceutical products from the source. This is a significant advantage that traditional stainless steel or titanium centrifugal equipment cannot easily achieve.
Rapid Phase Separation: Breaking Emulsions Within Seconds Under Centrifugal Force, Maximizing Efficiency
The CWL-M centrifugal extractor utilizes a stable centrifugal force field generated by high-speed rotation, enabling intensive mixing and instantaneous clarification separation of light and heavy phases within an extremely short period.
For systems that are highly prone to forming stable emulsions, the equipment effectively disrupts interfacial films, achieving clear and sharp two-phase separation.
The mass transfer efficiency of a single unit is significantly higher than that of traditional mixer-settlers, greatly reducing the required number of stages while maintaining extraction performance at an industry-leading level.
Fully Enclosed Explosion-Proof Design, Supporting Green and Safe Production
The entire equipment adopts a fully enclosed explosion-proof structure, equipped with high-performance mechanical seals and nitrogen protection interfaces, effectively suppressing uncontrolled emissions of VOCs (volatile organic compounds). This not only improves the operating environment and meets increasingly stringent international environmental regulations but also significantly reduces solvent losses, helping users save considerable raw material costs.
Linear Scale-Up: From Laboratory Research to Industrial Production with Direct Parameter Transfer
The CWL-M series centrifugal extractor provides a complete range of models covering laboratory research, pilot-scale testing, and industrial-scale production. Thanks to its consistent fluid dynamics design and stable centrifugal field distribution, optimized process parameters obtained during small-scale testing (such as rotational speed, flow ratio, and residence time) can be directly transferred to industrial-scale equipment without repeated time-consuming process optimization. This greatly shortens the development cycle from product research and development to commercial production.
Summary of Application Benefits
Improved Yield: Rapid emulsion breaking and efficient separation significantly reduce the loss of target products caused by entrainment in residual emulsified phases.
Reduced Solvent Residues: Clear phase interfaces and low liquid holdup enable more thorough scrubbing, effectively reducing residual solvent levels in final products.
Protection of Heat-Sensitive Components: The extremely short contact time minimizes degradation and side reactions caused by high temperatures or prolonged agitation.
Reduced Overall Energy Consumption: The power consumption per unit throughput is only a small fraction of that of traditional mixer-setters. In addition, reduced replacement frequency of bearings and seals significantly lowers operation and maintenance costs.
