As a leading manufacturer in environmental technology, Qingdao Conqinphi Environmental Technology Group leverages over eight years of specialized expertise to deliver the CONQINPHI Concentration Machine. This Double Effect External Circulation Vacuum Evaporator represents a significant advancement in industrial liquid concentration, designed to maximize efficiency and minimize operational costs for our global clientele across diverse sectors. Our commitment to integrating robust engineering with sustainable practices is evident in every system we produce, ensuring reliable performance that meets the rigorous demands of modern production facilities.
This system is engineered to handle a wide range of feedstocks, from food and pharmaceutical solutions to chemical and wastewater streams. Its core value lies in its ability to dramatically reduce energy consumption compared to single-effect evaporators, while achieving high concentrations of solids with minimal product degradation. Operating from our expansive 10,000-30,000 square meter facility, we control the entire manufacturing process, guaranteeing quality and consistency for partners in North America, South America, Europe, Asia, and beyond.
Core Technical Features & Operational Advantages:
- Dual-Effect Efficiency: Utilizes the vapor from the first effect as the heating source for the second effect, significantly reducing steam consumption by up to 50% compared to single-effect units.
- External Circulation Design: Features a large-diameter external circulation pipe that promotes stable boiling, prevents scaling, and is easier to clean and maintain.
- Advanced Vacuum Operation: Operates under high vacuum conditions, lowering the boiling point of the solvent. This is crucial for heat-sensitive materials, preserving product quality and preventing thermal degradation.
- Customizable Configuration: Systems are tailored to client-specific needs, including capacity, construction materials (SS304, SS316L, duplex steel), heat source (steam, thermal oil, electric), and level of automation.
- Integrated Separation & Condensation: Equipped with efficient separators to prevent liquid entrainment and condensers to recover distilled water or solvent, enhancing overall process yield.
Detailed Technical Specifications & Configurations:
| Parameter | Specification / Option | Client Benefit |
| Standard Evaporation Capacity | 500 - 50,000 kg/h (water evaporation) | Scalable solution for various production volumes. |
| Operating Vacuum Degree | -0.08 to -0.095 MPa (adjustable) | Low-temperature evaporation protects heat-sensitive products. |
| Heating Steam Pressure | 0.2 - 0.8 MPa (saturated steam) | Compatible with standard industrial boiler systems. |
| Final Concentration Range | Up to 40-70% solids (depending on viscosity) | Achieves high dry solid content, reducing downstream drying costs. |
| Main Construction Material | SS304, SS316L, Titanium, Duplex Steel | Corrosion resistance for acidic, alkaline, or saline solutions. |
| Control System | PLC + Touch Screen HMI (Siemens/Mitsubishi) | Ensures stable, repeatable operation with minimal manual intervention. |
Tangible Benefits for Your Operation:
- Substantial Energy Savings: The double-effect design reuses latent heat, cutting steam requirements by nearly half, leading to a rapid return on investment.
- Enhanced Product Quality: Gentle vacuum evaporation minimizes thermal stress, preserving flavors, colors, active ingredients, and nutritional value in food and pharma applications.
- Reduced Environmental Footprint: Concentrates waste streams, lowering disposal volumes and costs. Optionally integrates with MVR for near-zero steam consumption.
- Operational Reliability & Ease of Maintenance: The external circulation design minimizes fouling and allows for easier inspection and cleaning, reducing downtime.
- Comprehensive Solution: We provide a complete package including pre-treatment advice, evaporator, condenser, vacuum system, pumps, and controls, ensuring seamless integration.

Frequently Asked Questions (FAQ)
Q1: What are the main applications for this double-effect evaporator?
A1: This machine is highly versatile and is commonly used for concentrating fruit juices, dairy products, pharmaceutical extracts, chemical solutions, and for treating industrial wastewater by reducing its volume and recovering valuable components or water.
Q2: How does the "double effect" design save energy?
A2: In a double-effect system, the vapor generated from boiling the liquid in the first effect is not wasted. Instead, it is used as the heating source for the second effect. This reuse of latent heat can reduce steam consumption by approximately 50% compared to a single-effect evaporator performing the same duty.
Q3: What is the advantage of the external circulation design?
A3: The external circulation loop promotes more stable and controlled boiling over a large heat transfer area. It helps prevent localized overheating and scaling, allows for higher circulation velocity (reducing fouling), and makes the heating tubes and chamber more accessible for inspection and mechanical cleaning.
Q4: Can this system handle viscous or fouling materials?
A4: Yes, the external circulation design is particularly suitable for viscous liquids and materials prone to fouling or crystallization. The high circulation rate helps keep solids in suspension and minimizes scaling on heat transfer surfaces. For severe cases, forced circulation pumps or specific anti-scaling designs are available.
Q5: What level of automation is provided?
A5: The system typically comes with a fully automated PLC control system. This includes automatic control of feed flow, steam pressure, vacuum level, concentration density (via Brix or conductivity meter), and condensate discharge. The touch-screen HMI allows for easy monitoring, recipe management, and data logging.
Q6: What after-sales support and services do you offer?
A6: As a manufacturer, we provide comprehensive support including detailed installation drawings, remote guidance, on-site commissioning (optional), operator training, and a supply of spare parts. Our technical team is available for ongoing consultation to ensure optimal system performance.
Q7: Is the system customizable for specific feed characteristics?
A7> Absolutely. We consider key feed parameters like composition, pH, initial and target concentration, fouling potential, and required final product quality. Based on this, we can customize the material of construction, heat exchanger type, separation system, and control logic to ensure efficient and reliable operation for your specific process.
Q8: What is the typical lead time for such a system?
A8: Lead time depends on the complexity and capacity of the system. For standard configurations, it generally ranges from 60 to 120 days after order confirmation and finalization of technical specifications. We maintain efficient production workflows in our large factory to meet project timelines.
