As a leading manufacturer with a decade of experience in environmental technology, Qingdao Conqinphi Environmental Technology Group is proud to present our specialized Compact Double-effect MVR Evaporator. Designed specifically for laboratory-scale evaporation trials, this unit is engineered to provide researchers and process developers with a reliable, scalable platform for testing concentration, crystallization, and solvent recovery processes. Operating from our 10,000-30,000 square meter facility, we understand the critical need for precise, repeatable data in R&D, and this evaporator is built to deliver just that, helping you bridge the gap between bench-scale experiments and full-scale production with confidence.
The core innovation of this system lies in its integration of Mechanical Vapor Recompression (MVR) technology within a compact, double-effect configuration. This design maximizes energy efficiency—a key concern in evaporation processes—by reusing the latent heat of vaporized solvent. The first effect generates vapor, which is then mechanically compressed to raise its temperature and pressure. This higher-energy vapor then serves as the heating medium for the second effect, significantly reducing the external energy input required compared to traditional single-effect or thermal vapor recompression units. For laboratory settings, this means lower operating costs and the ability to simulate energy-efficient industrial processes accurately.
Key Features and Technical Advantages:
- Precision Scalability: The compact design is tailored for low-volume processing, allowing you to test with small sample quantities while generating data directly relevant to scaling up. All wetted parts are typically constructed from high-grade stainless steel, with 316L available for corrosive applications.
- Advanced Process Control: Equipped with a user-friendly PLC and touch-screen HMI, the system allows for precise control over critical parameters such as temperature, pressure, vacuum level, and feed rate. Automated sequences can be programmed for consistent trial conditions.
- Flexible Configuration: The system can be configured for various modes of operation, including forced circulation, falling film, or a combination, to suit different fluid viscosities and fouling tendencies. The heating source can be electric or steam-based, depending on lab infrastructure.
- Comprehensive Data Logging: Integrated sensors and data logging capabilities enable detailed recording of all process variables, essential for analysis, reporting, and process optimization.
- Modular & Serviceable Design: Despite its compact footprint, the unit is designed for easy access to key components like the compressor, heat exchangers, and pumps, facilitating maintenance and cleaning between trials.

Benefits for Your Laboratory: Investing in this specialized evaporator translates to tangible benefits for your R&D or quality control operations. You gain the ability to optimize process parameters (temperature, residence time, concentration ratio) on a small scale, minimizing waste of valuable raw materials. It enables accurate feasibility studies for new products or waste stream treatment. The energy-efficient MVR process provides realistic data on operational costs for future plant design. Ultimately, it de-risks scale-up by identifying potential issues like fouling, foaming, or product degradation early in the development cycle.
Frequently Asked Questions (FAQ):
-
Q: What types of solutions or materials can this lab MVR evaporator handle?
A: It is suitable for a wide range of aqueous solutions, including food extracts, pharmaceutical intermediates, chemical process liquors, and wastewater streams. The material of construction can be selected based on corrosion requirements. -
Q: How does the double-effect MVR design save energy compared to a single-effect unit?
A: In a double-effect system, vapor from the first effect is compressed and used to heat the second effect. This reuses latent heat, dramatically reducing the fresh steam or electrical energy needed per unit of solvent evaporated, often by 50% or more compared to single-effect. -
Q: Is the system easy to clean and maintain between different trial batches?
A: Yes. The design emphasizes cleanability with CIP (Clean-in-Place) capabilities available. Major components are accessible, and connections are designed for disassembly when necessary for thorough cleaning or inspection. -
Q: Can the evaporator be used for crystallization trials?
A: Absolutely. By controlling the concentration and temperature profile, the system can be operated to achieve supersaturation and initiate crystallization. Optional sight glasses and sampling ports can be incorporated for monitoring crystal growth. -
Q: What level of automation and data output does the control system provide?
A: The PLC system allows for fully automatic operation once parameters are set. It provides real-time monitoring, alarm functions, and detailed data logging of all key parameters (temps, pressures, flows) which can be exported for analysis. -
Q: Do you provide support for installation and initial operation?
A: Yes, we offer comprehensive technical support, including detailed operational manuals, remote guidance, and on-site installation and training services available upon request to ensure you can start your trials effectively. -
Q: How customizable is the unit for our specific lab space and utility connections?
A> The compact design is inherently flexible. We can adapt the footprint, utility connection points (for water, power, drain), and even certain process features to integrate smoothly into your existing laboratory layout.
