Explore our core industrial equipment engineered for maximum thermal efficiency, robust operation, and long-term reliability.
How modern process industries leverage advanced evaporation plants to optimize resource recovery and energy consumption.
In the modern industrial sector, thermal concentration is one of the most energy-intensive processes. Global manufacturing facilities are rapidly transitioning away from traditional multi-effect steam evaporators toward Mechanical Vapor Recompression (MVR) technology. MVR systems recycle latent heat from secondary vapor, reducing utility steam consumption by up to 90% and significantly lowering carbon footprints.
Jiangsu Zongheng is at the forefront of this transition, delivering custom-engineered MVR evaporation plants that integrate high-efficiency centrifugal compressors and falling film technology to maximize thermal economy.
Environmental regulations worldwide are mandating strict limits on industrial wastewater discharge. Evaporators are critical components in achieving Zero Liquid Discharge (ZLD). By concentrating industrial effluents to their saturation points, factories can recover clean distillate for process reuse while crystallizing solid wastes for safe disposal or byproduct commercialization.
From chemical processing plants to alcohol DDGS systems, our forced circulation evaporators handle high-fouling and high-viscosity liquids, ensuring continuous operation under severe conditions.
Integrating smart automation, advanced metallurgy, and hybrid thermal systems for next-generation efficiency.
Modern evaporation plants are increasingly integrated with AI-driven control loops. Real-time monitoring of heat transfer coefficients, boiling point elevation, and scaling rates allows operators to schedule preventive clean-in-place (CIP) cycles, minimizing downtime and maintaining optimal thermal efficiency.
To withstand highly corrosive environments typical in chemical and pharmaceutical wastewater, evaporators are shifting toward advanced materials. We specialize in fabricating pressure vessels using high-grade stainless steels (316L, 2205 duplex), Titanium, Hastelloy, and other exotic alloys certified under international standards.
The future lies in hybrid systems that combine multiple thermal technologies. By pairing waste heat evaporators with mechanical vapor recompression and tube bundle dryers, industrial plants can capture low-grade energy from drying vapors to preheat feed liquids, creating a closed-loop energy ecosystem.
Tailored evaporation and drying solutions designed to meet the unique operational demands of diverse industrial sectors.
In starch processing facilities, maintaining product purity and preventing thermal degradation of heat-sensitive sugars is paramount. Our falling film evaporators provide short residence times and precise temperature control, ensuring high-concentration glucose, maltose, and fructose syrups without color degradation.
The production of Distillers Dried Grains with Solubles (DDGS) requires efficient concentration of thin stillage. Our waste heat evaporators utilize the exhaust steam from dryers to concentrate the stillage before mixing it with wet grains, significantly reducing the overall energy input of the ethanol plant.
Highly saline wastewater from chemical synthesis and pharmaceutical formulation cannot be discharged directly. Forced circulation evaporators drive the liquid through heat exchangers at high velocities, preventing crystallization on tube walls and enabling continuous concentration up to solid precipitation.

Expert answers to common technical queries regarding industrial evaporation and drying systems.
An MVR (Mechanical Vapor Recompression) plant uses a mechanical compressor to compress the secondary vapor generated during evaporation. This increases the vapor's temperature and pressure, allowing it to be reused as the heating medium in the same system. Because it recycles the latent heat of vaporization, it requires only electrical energy to run the compressor and minimal fresh steam, reducing energy consumption by up to 90% compared to traditional multi-effect systems.
Forced circulation evaporators use high-capacity circulation pumps to drive the process liquid through the heat exchanger tubes at high velocities (typically 2-3 m/s). The static head of the liquid prevents boiling inside the tubes. Boiling and subsequent concentration only occur when the liquid enters the flash separator. This high velocity and suppressed boiling design prevent crystallization, scaling, and fouling on the heat transfer surfaces, making it ideal for highly concentrated, viscous, or solid-containing slurries.
Depending on the chemical composition, chloride concentration, and pH of the wastewater, we select materials ranging from high-grade stainless steels (304, 316L) to duplex stainless steels (2205, 2507), Titanium (Gr. 2), and nickel-based alloys like Hastelloy. All materials are sourced from certified suppliers and fabricated under strict quality control guidelines to ensure corrosion resistance and structural integrity.
