Discover our range of advanced concentration, evaporation, and downstream processing equipment engineered for low operating footprint and maximum recovery efficiency.
Modern bio-refineries, industrial distilleries, and biochemical complexes worldwide face escalating pressure to lower energy footprints and satisfy rigorous regional compliance standards. In the context of global decarbonization, industrial ethanol evaporation is no longer merely a unit operation; it is a critical energy hub. Efficient recovery of volatile solvents like ethanol demands precise control of pressure differentials, vapor recompression metrics, and thermal boundary layers.
Whether processing corn-to-ethanol, sugarcane-based bio-refining, or chemical-grade synthetics, procurement directors in Europe, North America, and Southeast Asia prioritize systems that mitigate operational expenditures (OPEX) while securing local safety approvals. A core element is the CE Certification, which guarantees adherence to strict European health, safety, and environmental protection benchmarks (including the Pressure Equipment Directive 2014/68/EU).
Additionally, compliance with ASME "U" Stamp requirements confirms that structural materials, fabrication procedures, and non-destructive testing (NDT) satisfy global boiler and pressure vessel codes. As a premium manufacturer, Jiangsu Zongheng integrates both CE and ASME architectures, offering plants a dual pathway to rapid regional integration and low-risk operational deployment.
Our solutions span evaporation plants, dewatering screw presses, starch cyclones, and dryers. Understanding how these systems work helps plants optimize their mass and energy balances.
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 dry spots, which lead to fouling. This maintains high thermal efficiency and operational stability. By maintaining tight control over delta T (temperature difference) and liquor distribution headers, our plants achieve high heat transfer coefficients and consistent operational stability.
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.
This drying technology is crucial for downstream processing of starch cake, feed byproducts, and industrial residues, transferring dry solids directly into storage or packaging lines without heat-degrading the organic fractions.
Different industrial processes demand distinct thermodynamic profiles. We design and deliver custom systems configured to feed characteristics like viscosity, boiling point elevation, and fouling rates.
We provide energy-efficient, high-performance evaporation solutions designed to optimize steam consumption and maximize condensate reuse in industrial ethanol recovery operations.
For high-viscosity media or processes with crystallization risks. Zongheng is a premier Chinese manufacturer specializing in forced circulation evaporators featuring high-velocity tube bundles to prevent scaling.
Mechanical Vapor Recompression (MVR) plants recycle low-temperature waste vapor by compressing it, raising its enthalpy, and reusing it as the heating medium. This cuts utility steam demands significantly.
This design integrates multiple waste heat sources—including drying vapors, condenser exhaust, and low-pressure flash steam—substantially lowering fresh steam usage.
Our infrastructure and engineering capacity back every technical guarantee, supporting your project from raw design to long-term commissioning.
Since our founding in 1992, we have grown from a local machinery workshop into a modern, high-tech enterprise holding ASME U stamps and CE certifications.

Maximizing efficiency in ethanol concentration requires integrating multiple plant components into a cohesive thermodynamic loop. By analyzing mass balances, Jiangsu Zongheng provides end-to-end integration pathways.
In bioethanol plants using corn or grains, raw starch must be extracted, washed, and hydrolyzed. Spent grains are then recovered as valuable DDGS feed byproducts. Our equipment covers this entire sequence:
Starch Washing Cyclones (YDX Series) purify raw starch slurry, preparing it for fermentation. The residual waste mash and thin stillage flow directly into our Falling Film or MVR Evaporators to concentrate solids up to 35-45%. This syrup is then combined with wet grains and dried using our ZXG Tube Bundle Dryer (an indirect steam-drying unit operating under low oxygen) or the Single Screw Press for initial mechanical dewatering.
Delivering heavy industrial machinery across international borders requires rigorous compliance verification. At Jiangsu Zongheng, we support global operations with a robust technical framework.
For European buyers, our ethanol evaporators carry full CE markings and comply with the Pressure Equipment Directive (PED 2014/68/EU). This includes comprehensive weld testing, radiography, hydrostatic verification, and pressure safety relief calculations, ensuring seamless integration into European production plants.
For installations in the Americas and international oil/chemical fields, our manufacturing complies with ASME Section VIII Division 1 guidelines. Authorized inspectors verify all materials, design drawings, and pressure computations prior to shop fabrication.
We provide localized engineering support, covering structural calculations, pipe layout stress analysis, field piping supervision, control panel configuration, and trial operations. Our engineers guide plant staff from water test trials to full-load ethanol concentration runs.
