Learn MoreIndustrial concentration and drying processes demand high thermal precision, structural stability, and reliable performance. For over three decades, Jiangsu Zongheng Concentrating and Drying Equipment Co., Ltd. has designed and engineered advanced heat exchangers that address the technical challenges faced by global manufacturing sectors.
Thermal separation relies on optimizing the latent heat of vaporization while keeping energy inputs low. Modern manufacturing demands that evaporator systems perform under various parameters. From handling viscous materials with high solids content to processing delicate, heat-sensitive organics, choosing the correct equipment configuration directly impacts your facility's operational efficiency and bottom line.
By using premium alloys, optimizing fluid velocity configurations, and integrating multi-effect recycling pathways, our design teams configure systems that limit scaling, sustain high heat transfer rates, and lower maintenance downtime.
An in-depth look at our primary processing configurations developed to handle complex liquid separation and bulk drying requirements.
Engineered to process heat-sensitive liquids by establishing a uniform, thin film flowing down vertical tubes. This thin film configuration minimizes residence time, prevents thermal degradation, and maintains high heat transfer coefficients. Ideal for milk, juice, sugar solutions, and organic solvents.
Developed to manage high-viscosity products or materials prone to scaling and crystallization. High-efficiency recirculating pumps drive fluid through the heat exchanger tubes at high velocities, suppressing boiling inside the tubes to prevent scaling. Vaporization occurs inside the separator vessel.
Mechanical Vapor Recompression represents the cutting edge of energy recovery. By compressing the exhaust steam using a mechanical compressor, its thermal energy is elevated and returned back as heating steam for the process. This recycling loop reduces overall boiler fuel consumption by up to 90%.
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.
An indirect steam heating solution utilizing a rotating tube bundle inside a stationary shell. The design delivers maximum heat transfer surface area per unit volume. Featuring low-oxygen operating parameters and gentle material turning, it prevents product degradation and is suitable for starch, DDGS, and light chemicals.
Specifically engineered for refining starch slurries, removing impurities, and concentrating starch granules. Utilizing multiclone engineering concepts, our design achieves precise liquid-solid separation to maximize starch purity and protein yield in wet milling applications.
Procuring capital-intensive thermal processing equipment from China offers distinct cost, delivery, and scaling advantages. However, achieving high quality requires partnership with established, certified manufacturers. Located in Yixing, Jiangsu—China’s primary industrial fabrication hub—our facility provides key logistical and engineering benefits:
Operating pressure vessels globally requires strict compliance with local codes and regulatory bodies. Jiangsu Zongheng ensures smooth customs clearance and commissioning through international certification standards:
ASME "U" Stamp Authorization: Certified since 2012, our shop is authorized to design and manufacture pressure vessels conforming to ASME Section VIII Division 1. This facilitates approval by local inspectors across North America and South America.
CE-PED Compliance: Our pressure equipment designs meet the European Union's Pressure Equipment Directive (PED 2014/68/EU), allowing for easy CE marking and delivery across European regions.
Class III Pressure Vessel Designations: We hold the license for manufacturing Class III medium and low-pressure vessels in China, demonstrating the quality of our QA/QC welding processes and non-destructive testing (NDT).
To support overseas partners, we offer localization services including structural wind/seismic calculations, regional electrical adaptations (UL/CSA/CE certified components), and remote commissioning support.
Key shifting patterns that global engineering procurement officers track when planning new installations or retrofitting older facilities.
Fossil fuel limitations have forced chemical complexes to reduce open steam consumption. System designs are shifting from multi-effect steam-heated evaporators toward electric-driven MVR compressors. By using green electricity to run MVR systems, plants significantly lower their carbon intensity footprint.
Zero Liquid Discharge (ZLD) mandates require processing streams containing high chlorides, organic toxins, and varying pH levels. Utilizing premium alloys like Titanium Gr. 2, Super Duplex, and Hastelloy inside the heat exchanger bundle ensures reliable operation under harsh conditions.
Modern chemical plants rely on centralized control rooms. Our evaporator units feature integrated instrumentation arrays (flowmeters, density sensors, boiling point rise monitors) combined with Siemens or Allen-Bradley PLC architectures to automate operation and handle process fluctuations.

How our industrial evaporator systems are integrated across different processes to optimize operations.
Our falling film evaporators concentrate corn steep liquor (CSL), while the starch cyclones refine starch milk. Wet starch is dried in MQG airflow units and bundle dryers, generating stable corn starch products.
In dry-mill ethanol operations, decanter thin stillage is concentrated using multi-effect waste heat evaporators. It is then combined with wet grains and processed in ZXG tube bundle dryers to produce high-value DDGS feed.
Our forced circulation systems process chemical wastewater and brine solutions. Concentrating products to crystallization limits allows for the separation of pure mineral salts and clean water recovery.
Our manufacturing facility undergoes regular testing and inspections by global classification and regulatory bodies.
Answering common engineering and procurement questions regarding design options, energy conservation, and system selection.
The choice is determined by the fluid's properties. Falling film evaporators are suited for clean, low-viscosity, and heat-sensitive fluids due to their thin film heat transfer and short residence times. If the liquid contains suspended solids, is prone to fouling, or exhibits high viscosity, a forced circulation evaporator is chosen to prevent scaling within the heat exchanger tubes.
Traditional multi-effect evaporators use fresh boiler steam in the first effect and discard or condense vapor from the final stage. Mechanical Vapor Recompression (MVR) uses a mechanical compressor to compress the generated exhaust vapor, raising its temperature and pressure so it can be reused as the heating source. This configuration reduces boiler steam demand and overall energy usage by up to 90%.
Yes. We have held the ASME "U" Stamp authorization since 2012, and our facilities are regularly audited. All components, material selections, welding procedures (WPS), and inspections conform to ASME Section VIII Div 1. For European projects, we supply systems built to CE-PED directives, ensuring compliance with local safety regulations.
ZXG Tube Bundle Dryers are widely used to dry loose, non-sticky materials in starch refining, alcohol production (DDGS), brewing grain recovery, and light chemical processing. They use indirect steam heating to dry heat-sensitive biological products safely in a low-oxygen environment.
