Qingdao Conqinphi Environmental Technology Group Co., Ltd. proudly presents our Pharmaceutical Falling Film Evaporation System for Solvent Recovery and Concentration. As a leading manufacturer with over 8 years of experience, we have designed this system to meet the strictest pharmaceutical standards, ensuring efficient solvent recovery and precise concentration of heat-sensitive materials. Our advanced falling film technology minimizes thermal degradation, making it ideal for high-value pharmaceutical intermediates and active ingredients. With a factory spanning 10,000-30,000 square meters and a dedicated team of 201-300 employees, we deliver reliable, customizable solutions to clients worldwide.
This evaporation system is engineered to achieve up to 95% solvent recovery with low energy consumption, while maintaining product quality. The falling film design ensures a thin liquid film flows downward inside heated tubes, promoting rapid evaporation at low temperatures. This is particularly beneficial for recovering solvents like ethanol, methanol, acetone, and ethyl acetate, as well as concentrating pharmaceutical solutions without compromising purity.
Key Features & Technical Specifications
- High-Efficiency Falling Film Design: Short residence time, low temperature difference, and high heat transfer coefficient (up to 1200 W/m²·K).
- Solvent Recovery & Concentration: Recovers up to 99% of solvents (depending on type) and concentrates solutions to desired final concentration.
- Vacuum Operation: Optional vacuum system allows operation at reduced temperatures (as low as 40°C), protecting heat-sensitive compounds.
- Customizable Capacity: Evaporation capacity ranges from 50 L/h to 5000 L/h, tailor-made to your production scale.
- GMP-Compliant Construction: All wetted parts are made of stainless steel 304/316L with mirror-polished surfaces (Ra ≤ 0.4 μm) for easy cleaning and sterilization.
- Automated Control: PLC-based control with touch screen interface for precise monitoring of temperature, pressure, flow rate, and liquid level.
- Integrated Safety Features: Overpressure protection, emergency shutdown, and leak detection ensure safe operation.
- Modular Design: Includes pre-assembled skid-mounted units for quick installation and minimal footprint.

Frequently Asked Questions (FAQ)
-
Q: What types of solvents can this system recover?
A: It is suitable for recovering most common organic solvents including ethanol, methanol, acetone, ethyl acetate, isopropanol, toluene, and many others. The system can be customized for specific solvent mixtures. -
Q: How does the falling film design differ from other evaporators?
A: In falling film evaporators, the liquid flows as a thin film down the inner walls of heated tubes, allowing rapid heat transfer and short residence time. This minimizes thermal degradation and enables operation at lower temperatures, especially under vacuum. -
Q: Can the system handle viscous or fouling solutions?
A: Yes, with appropriate design modifications such as larger tube diameters, increased flow rates, or special distribution devices. We can tailor the system to your specific rheology. -
Q: What is the typical lead time for delivery?
A: Lead time depends on the complexity and capacity. Standard systems typically ship within 30-45 days after order confirmation. Custom systems may require 60-90 days. -
Q: Do you provide installation and commissioning support?
A: Yes, we offer on-site installation guidance and commissioning services. Our engineers can also provide remote support via video calls. -
Q: Is the system compliant with GMP and FDA regulations?
A: The system is designed to meet GMP guidelines. FDA compliance documentation can be provided upon request. We also offer materials certificates and validation protocols. -
Q: Can I run the system in batch mode as well as continuous?
A: Our standard design is continuous, but we can incorporate a recirculation loop or buffer tank to allow batch operation. Please specify your requirement. -
Q: What is the warranty period?
A: We provide a standard 12-month warranty from the date of commissioning. Extended warranty options are available.
