In the modern process industries, thermal separation technologies are undergoing a paradigm shift driven by energy conservation, carbon neutrality mandates, and the need to process highly complex, heat-sensitive, and viscous media. Wiped Film Evaporators (WFE), alongside advanced Falling Film and Forced Circulation systems, represent the pinnacle of high-efficiency thermal concentration. By utilizing mechanical agitation to create a highly turbulent, thin liquid film on the heat transfer surface, WFEs facilitate exceptionally high heat transfer coefficients even with highly viscous materials, while maintaining extremely short residence times to prevent thermal degradation.
Globally, the demand for CE-certified and ASME-compliant evaporation plants is surging. Industries ranging from food fermentation, starch processing, and bio-ethanol production to chemical synthesis, pharmaceutical manufacturing, and Zero Liquid Discharge (ZLD) wastewater treatment require robust, certified equipment. The European Union's Pressure Equipment Directive (PED) 2014/68/EU, represented by the CE marking, has become a global benchmark for safety, reliability, and mechanical integrity. As leading manufacturers, we integrate advanced thermodynamic modeling with state-of-the-art mechanical fabrication to deliver systems that meet these stringent regulatory frameworks while optimizing operational expenditures (OPEX).
Mechanical Vapor Recompression (MVR) represents the future of energy-efficient evaporation. By recycling the latent heat of secondary vapor through mechanical compression, MVR systems reduce steam consumption by up to 90%, offering rapid return on investment and aligning with global decarbonization goals.
To handle corrosive media, high-chloride wastewater, and acidic process streams, our systems utilize advanced alloys including Duplex Stainless Steel (2205/2507), Titanium Gr. 2, Hastelloy C276, and high-purity Austenitic steels, ensuring long-term structural integrity and corrosion resistance.
Future-ready evaporation plants incorporate real-time fouling monitoring, predictive maintenance algorithms, and automated CIP (Clean-in-Place) systems. By integrating PLC-based control architectures, we optimize thermodynamic performance dynamically under varying feed conditions.
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.

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.
