View ProductIndustrial evaporation is a cornerstone thermodynamic process driving massive resource recovery, liquid concentration, and Zero Liquid Discharge (ZLD) practices worldwide. In an era marked by strict carbon reduction mandates and volatile energy markets, industrial facilities are discarding traditional, high-consumption multi-effect thermal systems. The modern focus is fixed on energy-recovering technologies, specifically Mechanical Vapor Recompression (MVR) and optimized Falling Film Evaporators.
For global purchasers across Europe, North America, and the Middle East, compliance with CE Certification (such as the Pressure Equipment Directive 2014/68/EU) is no longer optional. It is a fundamental benchmark for structural integrity, process safety, and manufacturing transparency. Choosing an engineering partner that natively executes these global guidelines ensures seamless local regulatory integration and minimizes project risk.
Modern industrial evaporators achieve high thermal performance by manipulating boiling point elevations under vacuum conditions. MVR systems, for instance, reuse latent heat of vaporization by compressing secondary vapor using centrifugal fans or turbo compressors. This reduces external steam demand to virtually zero, offering operational savings that offset initial investment costs within 1.5 to 3 years.
Chinese evaporator manufacturers have transitioned from low-cost fabricators to technology-driven industrial leaders. The concentration of chemical, environmental, and mechanical supply chains in the Yangtze River Delta allows factories to engineer and assemble sophisticated thermal plants rapidly.
Direct proximity to top-tier steel and titanium refineries enables cost-effective procurement of specialty alloys, including Duplex SS 2205, Titanium Gr. 2, and Hastelloy. This guarantees superior corrosion resistance in high-salinity industrial applications.
Equipped with automatic orbital welding, specialized tube sheet expanders, and complete Non-Destructive Testing (NDT) rooms, we execute pressure vessel welds that satisfy both Chinese GB150 standards and international ASME code credentials.
Our facility provides comprehensive workshop pre-assembly and hydrostatic pressure testing, ensuring modular evaporator sections connect with millimetric precision upon arrival at international installation sites.
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.
Typical applications include heat-sensitive chemical solutions, food processing, glucose concentration, and high-purity starch refining.
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.
Ideal for drying bulk crystalline chemical components, organic compounds, and food fibers where moisture content must be reduced within seconds.
Specifically designed to handle heavily fouling liquids, high concentrations of suspended solids, or crystallizing substances. High-velocity axial circulation pumps maintain high turbulent velocities inside the heat exchanger tubes, preventing crystallization on surfaces.
Mechanical Vapor Recompression (MVR) utilizes clean electrical energy to compress secondary steam. This raises the steam temperature and enthalpy, feeding it back into the evaporator system to replace external fresh steam requirements.
Our ZXG Tube Bundle Dryer maintains slow rotation of heat-exchanging tubes inside a stationary shell, providing safe, low-oxygen drying for agricultural byproducts, chemical crystals, and gluten fibers.
Jiangsu Zongheng Concentrating and Drying Equipment Co., Ltd. (formerly Yixing Yangxi Light Industry Machinery Factory), founded in 1992, is located in Zhoutie Town, Yixing City, on the shores of the beautiful Taihu Lake. The company covers an area of over 54,000 square meters, with a production workshop area of over 22,000 square meters.
Jiangsu Zongheng is a modern high-tech enterprise specializing in the manufacturing of concentration, drying, starch industry, alcohol DDGS, and Category III medium & low-pressure vessel equipment. It is currently a member enterprise of the China Starch and Alcohol Association. Our products are widely used in industries such as food fermentation, alcohol, chemical, pharmaceutical, environmental protection, and petrochemical.
Established as Yixing Yangxi Light Industrial Machinery Factory, covering 15 mu with 45 employees.
Obtained ISO9001, establishing a baseline international quality management framework.
Recognized as a Jiangsu Provincial High-Tech Enterprise for technology achievements.
Acquired the Special Equipment Manufacturing License of the People's Republic of China.
Awarded ASME "U" Stamp authorization, marking entry into global process markets.
Achieved International Quality System Certification (Certificate No: 45021).
Currently employing over 120 personnel (including 3 senior engineers and 20+ engineers) across a 54,000㎡ facility.
Industrial concentration systems must adapt to regional inputs and specific fluid characteristics. We tailor each system to fit localized processes:
Concentration of high-density glucose, maltose, and sorbitol syrups requires uniform falling-film distribution to prevent caramelization and local scorching. Integrated wash cyclones refine starch to high purity levels prior to evaporation.
Our multi-effect and MVR systems are configured to process distillery spent wash (stillage), concentrating it into DDGS. This process turns environmental waste into valuable, nutrient-rich animal feed.
Dealing with high boiling point elevations in chemical effluent streams requires forced circulation crystallizers. Solid-salt output is subsequently dried and dewatered using high-performance single-screw presses.
