Explore our high-performance industrial evaporators, dryers, and separation machinery designed for global process standards.
The Cornerstone of Modern Thermal Concentration and Zero Liquid Discharge (ZLD) Strategies
In modern process engineering, the demand for energy conservation, environmental compliance, and high-purity product recovery has positioned the Multiple-Effect Evaporation System (MEES) as a critical technology. By utilizing a series of evaporation vessels (effects) operating under progressively lower pressures, the latent heat of the vapor generated in one effect is reused to heat the subsequent effect. This cascading thermodynamic design drastically reduces raw steam consumption, offering a highly optimized Gained Output Ratio (GOR) compared to single-effect systems.
For global enterprises operating within the European Economic Area (EEA) and other highly regulated jurisdictions, securing CE Certification is not merely a legal formality; it is a rigorous validation of mechanical integrity, pressure safety, and operational reliability. As a premier manufacturer, Jiangsu Zongheng designs and fabricates MEES solutions that comply fully with the Pressure Equipment Directive (PED) 2014/68/EU, ensuring seamless integration into global production lines.
Whether concentrating heat-sensitive food ingredients, processing corn steep liquor in starch plants, or executing complex Zero Liquid Discharge (ZLD) wastewater treatments in chemical facilities, our systems are custom-engineered to balance capital expenditure (CAPEX) with long-term operational efficiency (OPEX).
Pioneering the Next Generation of Thermal Separation and Energy Recovery Technologies
By combining Mechanical Vapor Recompression (MVR) with thermal vapor recompressors (TVR), our systems achieve unprecedented energy savings. MVR recycles the latent heat of secondary vapor using a mechanical compressor, virtually eliminating the need for fresh steam under steady-state operations, while TVR utilizes high-pressure motive steam to entrain low-pressure vapor, optimizing thermal efficiency in multi-effect configurations.
To withstand highly corrosive process media (such as high-chloride wastewater or acidic fermentation broths), we utilize premium alloys including Duplex Stainless Steel (2205/2507), Titanium (Gr. 2), and Hastelloy. Our proprietary liquid distribution designs and optimized tube velocities minimize boundary-layer fouling, extending continuous run times and reducing Clean-in-Place (CIP) frequencies.
Integrating IoT-enabled sensors and PLC-based control systems allows for real-time monitoring of boiling point elevation (BPE), liquid levels, and heat transfer coefficients. Predictive algorithms adjust feed rates and steam pressures dynamically, preventing dry-out and scaling while ensuring consistent output concentration even under fluctuating feed conditions.
Tailored Thermal Processing Systems for Diverse Global Sectors
In corn wet milling and starch processing, our falling film evaporators concentrate corn steep liquor (CSL) and glucose/fructose syrups. The short residence time prevents thermal degradation, preserving product color and nutritional value. Integrated with our starch washing cyclones and degerming mills, we provide complete, end-to-end processing lines.
For bioethanol and industrial alcohol production, managing Distillers Dried Grains with Solubles (DDGS) is critical. Our waste heat evaporators utilize flash steam and dryer exhaust vapors to concentrate thin stillage, significantly reducing the plant's overall carbon footprint and thermal energy consumption.
Chemical, pharmaceutical, and petrochemical plants generate complex, high-salinity wastewater. Our forced circulation evaporators and crystallizers are engineered to handle high-viscosity fluids and crystal precipitation, separating clean condensate from solid salts to achieve Zero Liquid Discharge compliance.

Leveraging Advanced Manufacturing Infrastructure for Global Cost and Quality Advantages
Jiangsu Zongheng's manufacturing facility in Yixing City represents the integration of traditional craftsmanship with modern industrial automation. Operating under a Factory 4.0 framework, our production lines utilize automated plasma cutting, robotic welding stations, and advanced tube-to-tubesheet orbital welding. This ensures high precision in heat exchanger fabrication, minimizing mechanical stress points and eliminating potential leakage paths.
Our strategic location in the Yangtze River Delta provides access to a robust, localized supply chain. From high-grade raw stainless steel to specialized valves, instrumentation, and control panels, we source materials efficiently, reducing lead times and shielding clients from global logistics disruptions. Furthermore, our in-house Non-Destructive Testing (NDT) capabilities—including radiographic, ultrasonic, and dye penetrant testing—guarantee that every weld seam meets ASME and CE pressure vessel requirements before leaving the factory floor.
Navigating International Regulatory Frameworks with Certified Engineering Expertise
Our engineering team designs pressure vessels, heat exchangers, and piping networks in strict compliance with the European Pressure Equipment Directive. We coordinate with notified bodies for design examination (Module B/H) and final inspection, ensuring hassle-free customs clearance and installation within the EU.
With our ASME "U" stamp authorization, we design and manufacture high-pressure evaporators and flash vessels that comply with North American safety codes. This dual-compliance capability (ASME + CE) makes us a preferred partner for multinational engineering firms.
We provide comprehensive documentation packages, including material test reports (MTRs), welding procedure specifications (WPS), and operating manuals in multiple languages. Our field service engineers are available globally for installation supervision, commissioning, and operator training.
Proven performance across agriculture, food processing, environmental engineering, and chemical industries.
Optimizing Capital Expenditure and Operational Costs for Long-Term Profitability
When procurement departments evaluate industrial evaporation systems, looking beyond the initial purchase price to analyze the Total Cost of Ownership (TCO) is essential. Over a typical 20-year operational lifespan, energy consumption (steam and electricity) represents up to 80% of the system's total cost. Our engineers focus on designing high-efficiency multiple-effect systems that minimize utility consumption.
By increasing the number of effects, steam consumption can be reduced significantly. For instance, a double-effect system consumes approximately 0.55 kg of steam per kg of water evaporated, whereas a five-effect system can reduce this to as low as 0.22 kg. When integrated with MVR technology, operational costs drop further, making the system highly sustainable. We work closely with global procurement teams to provide detailed ROI calculations, balancing the initial CAPEX of additional effects against the projected OPEX savings based on local utility rates.
