View DetailsIn falling film evaporation technology, the liquid distributor is the single most critical component determining overall system efficiency and operational reliability. The primary function of the distributor is to feed the process liquid uniformly to all heat transfer tubes. If the distribution is uneven, some tubes will receive insufficient liquid, leading to dry spots, localized overheating, product degradation, and rapid fouling or scaling.
Our engineering team utilizes advanced Computational Fluid Dynamics (CFD) modeling to simulate fluid behavior under varying viscosity, surface tension, and flow rate conditions. By optimizing the geometry of the distributor tray, we ensure a continuous, uniform thin film across the entire tube bundle, maximizing heat transfer coefficients while minimizing the minimum wetting rate requirement.
"A perfectly designed liquid distributor reduces fouling rates by up to 70% and increases the overall heat transfer coefficient (U-value) by 15-25%, directly translating to lower energy consumption and extended production runs."
Whether handling heat-sensitive food products, pharmaceutical intermediates, or aggressive industrial wastewater, our custom-engineered distributor designs are tailored to meet the exact rheological profile of your process fluid.
Pioneering the next generation of smart, zero-emission thermal concentration technologies.
Integrating real-time flow sensors and dynamic control valves to adjust liquid distribution dynamically, compensating for changes in feed concentration and viscosity during operation.
Combining Mechanical Vapor Recompression (MVR) with Thermal Vapor Recompression (TVR) to achieve ultra-low specific steam consumption, targeting near-zero carbon footprint operations.
Developing advanced hydrophobic and oleophobic tube coatings that prevent scale adhesion, extending cleaning cycles (CIP) and maintaining peak thermal performance over years of continuous service.
Tailored process engineering for global industrial sectors, optimizing resource recovery and energy efficiency.
In the starch industry, concentrating steepwater and glucose syrups requires precise temperature control to prevent caramelization. Our CE-certified falling film evaporators operate under deep vacuum, ensuring low boiling temperatures and preserving product color and quality. Integrated with our starch washing cyclones and dewatering screw presses, we offer complete plant solutions.
For distillery operations, concentrating thin stillage into syrup is highly energy-intensive. Our multi-effect falling film evaporators, integrated with waste heat recovery systems and tube bundle dryers, maximize energy integration, recycling low-grade vapors to minimize primary steam consumption.
Achieving Zero Liquid Discharge (ZLD) requires robust concentration systems capable of handling high salinity and scaling tendencies. Our forced circulation and falling film evaporator designs concentrate wastewater to near-saturation limits, facilitating efficient crystallization and water reuse.

Detailed operational principles and design advantages of our primary product lines.
Jiangsu Zongheng's MQG Airflow Dryer employs high-speed hot air to suspend and fluidize the material. By utilizing impulse airflow generated from precisely varied tube diameters, it continuously tumbles the particles while conveying them. This design ensures rapid, uniform, and efficient drying throughout the entire transportation process within the system, making it ideal for heat-sensitive materials requiring short exposure times.
A falling film evaporator efficiently concentrates heat-sensitive liquids. The feed liquid forms a thin film flowing down heated vertical tubes, where it partially evaporates. Vapor generated flows parallel to the liquid, enhancing the process. It ensures a short residence time and low operating temperature, preserving product quality. The system requires proper liquid distribution and complete surface wetting to prevent fouling and maintain high thermal efficiency and operational stability.
