Qingdao Conqinphi Environmental Technology Group Co., Ltd. has been a dedicated manufacturer of advanced environmental equipment since 2015. Our Cryogenic Falling Film Wastewater Plate Evaporator is engineered specifically for the demanding needs of pharmaceutical intermediates processing. With a robust 304 stainless steel construction and an operating temperature as low as -10°C, this evaporator ensures efficient concentration of heat-sensitive waste streams while maintaining product integrity. Backed by our 10,000-30,000 m² factory and experienced team of 201-300 employees, we deliver reliable solutions that meet global quality standards.
This evaporator utilizes the falling film principle on plate surfaces, maximizing heat transfer efficiency and minimizing fouling even under cryogenic conditions. Designed to handle wastewater from pharmaceutical intermediate production, it effectively separates solvents and concentrates active compounds, reducing disposal costs and enabling resource recovery. The 304SS material provides excellent corrosion resistance against organic acids and solvents commonly found in pharmaceutical effluents.
Key Product Features & Technical Specifications
- Falling Film Technology: Uniform liquid distribution across plates ensures thin film formation for rapid evaporation without thermal degradation.
- Cryogenic Operation (-10°C): Low-temperature processing preserves thermally labile pharmaceutical intermediates and reduces energy consumption compared to high-temperature evaporation.
- 304 Stainless Steel Construction: High resistance to corrosion, easy to clean, and compliant with pharmaceutical hygiene standards.
- Plate Heat Exchanger Design: Compact footprint, high heat transfer coefficient (up to 3000 W/m²·K), and easy scalability.
- Customizable Capacity: Available in multiple sizes from pilot scale (50 L/h) to industrial (10,000 L/h) to match specific production volumes.
- Integrated Vacuum System (Optional): Enhances evaporation at reduced temperatures, further protecting sensitive materials.
- Automation & Control: PLC-based control with real-time monitoring of temperature, pressure, and flow rate for consistent operation.
- Energy Efficiency: Low energy consumption per kilogram of water removed (approximately 0.8-1.2 kWh/kg), reducing operating costs.

Frequently Asked Questions
-
Q: What type of wastewater is suitable for this evaporator?
A: It is specifically designed for pharmaceutical intermediates wastewater containing organic solvents, acids, and heat-sensitive compounds. The 304SS material is compatible with most non-chloride environments. -
Q: Can the operating temperature be adjusted below -10°C?
A: The standard design supports -10°C. For lower temperatures, custom engineering is available upon request using specialized refrigerants and insulation. -
Q: How is the heat source supplied for cryogenic operation?
A: The evaporator typically uses a mechanical vapor recompression (MVR) system or a chilled water/glycol loop. The exact configuration depends on your site utilities and can be customized. -
Q: What cleaning and maintenance procedures are required?
A: The plate design allows easy access for manual cleaning or CIP (Clean-in-Place). We recommend periodic inspection of gaskets and seals. A maintenance manual is provided with each unit. -
Q: What capacity ranges do you offer?
A: We offer capacities from 50 L/h (pilot) up to 10,000 L/h (industrial). Intermediate sizes are customizable. Please provide your required evaporation rate for a quotation. -
Q: Do you provide installation and commissioning services?
A: Yes, we offer on-site installation supervision and commissioning by our experienced engineers. Remote support is also available for troubleshooting. -
Q: Can this evaporator be used for solvent recovery?
A: Absolutely. The condensed vapor contains valuable solvents that can be separated and reused, reducing raw material costs. A condenser and solvent collection system can be integrated. -
Q: What is the expected lifespan of the 304SS plates?
A: With proper operation and maintenance, the plates can last 10-15 years. The 304SS provides good corrosion resistance in pharmaceutical environments; for aggressive chemicals, a higher grade (e.g., 316L) is optional.
