Explore our highly integrated, energy-efficient drying systems and industrial evaporation plants custom-designed for heavy duty applications.
In modern process industries, thermal separation, drying, and concentration stand as cornerstone operations. Whether processing municipal residues, high-purity chemicals, biological fermentation broths, or grain derivatives, the thermodynamics and mechanical stability of your equipment directly dictate your system's operational expenditure (OPEX) and regulatory viability. Choosing a premium partner who builds CE certified drying systems and evaporative concentrators ensures compliance, processing safety, and long-term mechanical reliability.
This industry report acts as a technical whitepaper for senior procurement executives, design engineers, and plant managers. We analyze the core engineering parameters of falling film systems, forced circulation evaporators, tube bundle dryers, and airflow transport dryers. Through this analysis, we present the structural advantages of partnering with a top-tier Chinese manufacturing facility operating at the absolute peak of modern metallurgical standards.
When deploying heavy industrial thermal equipment in the European Economic Area (EEA) or in jurisdictions following European Harmonized Standards, a CE certificate is not a mere formality—it is a binding declaration of engineering compliance. The certification process verifies that the drying system satisfies safety rules laid out across multiple European Directives:
At Jiangsu Zongheng, our compliance protocols go beyond basic CE norms. In 2012, we obtained our American Society of Mechanical Engineers (ASME) "U" Stamp authorization, illustrating our competence in manufacturing high-pressure vessel configurations. Our engineering team bridges the gap between global pressure vessel standards, designing and delivering customized evaporative systems that easily pass local inspections.
Over the last three decades, China has transitioned from a low-overhead manufacturing center to a high-precision heavy engineering hub. By basing your equipment manufacturing in Yixing, Jiangsu—the heart of China's light industrial and environmental engineering cluster—you secure significant advantages in procurement speed, raw material quality, and capital optimization.
Vertical Integration & Raw Materials: We source high-performance alloys (including SS304, SS316L, Duplex 2205, Duplex 2507, and Grade 2 Titanium) directly from world-class domestic steel mills. This direct sourcing lowers raw material costs while securing mill test certificates (MTC) to guarantee material chemistry and physical properties.
Advanced Manufacturing Processes: Our 54,000+ square meter facility houses modern welding and assembly systems. With automatic tube-to-tubesheet orbital welding, massive plasma cutters, multi-axis rolling mills, and cleanrooms, we minimize manual welding errors. The result is structural durability, zero pinhole leaks in heat exchangers, and minimal maintenance shutdowns.

A closer look at the fluid dynamics, heat transfer, and mechanical engineering behind our principal processing product lines.
The ZXG Tube Bundle Dryer is engineered for safe, low-oxygen, indirect steam drying of bulk materials. The design features a rotating heating tube bundle enclosed within a stationary outer shell.
Steam flows inside the tubes while the material to be dried is continuously lifted and showered over the hot surfaces by external shovels. This provides highly efficient, uniform moisture reduction, making it ideal for processing corn germ, fiber, gluten, and DDGS.
Utilizing high-speed, turbulent hot air, the MQG Airflow Dryer suspends and fluidizes raw particulate feeds. An integrated impulse transport tube design features variable diameters, creating sudden pressure differentials.
These pressure changes cause the particles to tumble continuously while traveling through the system. This rapid flash evaporation process provides uniform drying within seconds, protecting heat-sensitive product surfaces from thermal degradation.
A falling film evaporator is engineered to concentrate highly heat-sensitive fluids. The process liquid enters at the top of the heating tubes, where our specialized distribution plates form a thin, uniform film down the inner tube walls.
As the film descends, it boils and evaporates. The co-current vapor flow helps pull the liquid film downward. This short residence time, coupled with low operating temperatures under vacuum, prevents fouling and thermal degradation.
Engineered for high-viscosity, crystallization-prone, and fouling-heavy industrial streams. In this design, high-capacity axial flow pumps maintain high fluid velocity inside the heat exchanger tubes.
This high velocity suppresses boiling inside the tubes, shifting vapor formation to the flash separator chamber instead. This design limits solid deposition on heat exchange surfaces, maintaining reliable, continuous operation.
Jiangsu Zongheng's single screw press delivers reliable, mechanical dewatering of high-solid fibrous slurries, starch residues, and grain pulps before thermal drying.
By using a variable pitch shaft and a heavy-duty screen cage, it continuously compresses material, removing free water. This process lowers the energy demand on downstream thermal dryers, saving on overall thermal operating costs.
Our YDX Starch Washing Cyclone and specialized Degerming Mills ensure efficient separation and processing in starch wet milling lines.
The degerming mills provide precise germ liberation without crushing the fragile kernels. Meanwhile, the multi-stage cyclone loops wash and separate starch from fibers and proteins, maintaining high product purity and yielding clean starch milk.
Every processing plant operates under unique localized conditions, including ambient moisture profiles, regional fuel costs, local emissions limits, and raw material variations. Understanding these operational differences is key to successful international equipment deployment.
Wet Milling & Starch Refining Scenarios: In potato, corn, or cassava starch plants, starch slurries must be processed rapidly to prevent fermentation and quality loss. Our integrated systems combine starch washing cyclones, dewatering screw presses, and flash dryers. These setups are designed to handle moisture variations while maintaining product purity.
DDGS Recoveries in Ethanol Distilleries: For fuel ethanol and potable alcohol producers, handling Distillers Dried Grains with Solubles (DDGS) requires robust evaporation and drying loops. Using waste heat evaporators coupled with ZXG Tube Bundle Dryers allows operators to reuse low-grade process steam. This significantly lowers energy usage per ton of dried product.
Zero Liquid Discharge (ZLD) Waste Scenarios: In chemical and pharmaceutical manufacturing, treating high-salt wastewater is a major operational challenge. By combining our multi-effect falling film evaporators with forced circulation crystallizers, plants can separate clean water from crystalline salts, meeting environmental discharge rules.
