Explore our premium range of industrial evaporators, dewatering screw presses, starch cyclones, and corn degerming mills engineered for robust operation.
In modern chemical, food, pharmaceutical, and wastewater processing sectors, thermal concentration remains a cornerstone separation technology. The global push towards environmental sustainability, zero-liquid-discharge (ZLD), and energy optimization has positioned CE-certified falling film and MVR (Mechanical Vapor Recompression) evaporators as essential industrial assets.
Commonly referred to in specialized sanitary industries as "White Film Evaporators" due to their processing of clean, food-grade, or clear liquids, these units require strict hygiene parameters and thermal accuracy. Maintaining a thin, turbulent falling film along the vertical tubes prevents scaling and avoids localized overheating, preserving the biological integrity of heat-sensitive raw materials.
Globally, European and North American compliance structures mandate pressure vessels to bear the CE Marking (under the Pressure Equipment Directive 2014/68/EU) or ASME U-Stamp certifications. Manufacturers capable of bridging high-precision metallurgical execution with cost-effective manufacturing hubs represent the vanguard of the current industrial procurement transition.
Understanding the unique factors that render Chinese industrial manufacturers globally competitive in pressure vessel and evaporator fabrication.
Located in Yixing, Jiangsu (Taihu Lake Basin), Jiangsu Zongheng is situated at the epicenter of China's chemical and light industrial machinery manufacturing cluster. Immediate proximity to high-grade alloy mills, precision casting shops, and automatic orbital welding specialists lowers lead times by up to 35% compared to Western competitors.
China's top factories don't just mimic Western blueprints. Jiangsu Zongheng maintains localized manufacturing lines certified under ASME (U stamp authorization), ISO 9001 quality systems, and CE Pressure Equipment Directive protocols. This ensures seamless import, installation, and workplace compliance verification in Europe and the Americas.
Every industrial liquid (slurry, organic acids, biological broths) behaves differently. Chinese engineering teams excel at integrating falling film evaporators with mechanical components like Zongheng Single Screw Presses or ZXG Tube Bundle Dryers to form cohesive waste-heat utilization configurations.
A deep engineering overview of the primary industrial machinery manufactured by Jiangsu Zongheng.
Including Falling Film, Forced Circulation, and energy-optimized MVR units. Formulated to minimize thermal contact time for heat-sensitive organic streams while maximizing heat transfer coefficients through proprietary liquid distribution plates.
Engineered for structural durability to handle solid-containing biomass, corn fiber, and spent grain. Combines physical compression and screen filtration to separate liquids from bulk solids with minimal energy consumption.
Employs an indirect steam heating model to continuously tumble wet cake particles along rotating heat-exchanging tubes, ensuring a safe, low-oxygen drying environment suited for high-moisture agricultural byproducts.
Utilizes high-speed dynamic thermal gas flows to suspend wet particles. The instant flash moisture evaporation ensures rapid processing of bulk starches or light organic solids without thermal degradation.
A specialized dry-milling configuration focused on the clean separation of maize kernels from the starch-heavy endosperm, preserving germ integrity and improving yields in downstream vegetable oil refineries.
YDX hydrocyclones configured in multi-stage washing setups. Utilizes centrifugal separation forces to achieve highly efficient counter-current washing, removing fine fiber residues and refining raw starch slurries to high purity.
Thermal concentration requirements vary distinctly by global region. European dairy and starch manufacturers operate under tight CO2 limits and high electricity rates. Here, MVR Evaporation Plants are highly favored; they use mechanical compressors to compress clean waste vapor, cycling it back into the heating chest to save up to 80% on steam costs.
In Contrast, Southeast Asian sugar factories and Latin American bio-ethanol processors often utilize multi-effect evaporators powered directly by cheap biomass (bagasse) steam. The main challenge here is managing tube scaling from heavy minerals. In these environments, Forced Circulation Evaporators with high-flow axial recirculating pumps are preferred to prevent fouling.
In the US Midwest, agricultural corn refining processes require large-scale dewatering systems. The integration of Zongheng Single Screw Presses alongside ZXG Tube Bundle Dryers allows for the efficient drying of wet fiber feeds, turning waste starch stream fractions into valuable animal feed byproducts (DDGS) with optimized thermal footprints.

Detailed engineering answers to the most common questions from plant operators and procurement directors.
"White Film" thermal concentration systems are primarily engineered for clear, heat-sensitive, or high-purity sanitary fluids (such as corn starch steepwater, clean chemicals, and pharmaceutical compounds). The key design distinction lies in the distribution mechanism and surface wetting. We utilize precision laser-cut liquid distribution trays at the top of the tube sheet to establish a highly uniform thin film. This prevents dry-wall effects (where lack of liquid leads to product burning and scale buildup) and maximizes the overall heat transfer coefficient (U-value).
MVR systems run a mechanical compressor (either centrifugal or roots type) to re-compress the vapor generated from the product. This increases the temperature and pressure of the vapor, allowing it to be reused as the heating medium for the same effect. While the initial capital expenditure (CAPEX) for MVR is higher due to the compressor technology, the operational cost (OPEX) is significantly lower. MVR systems typically consume only 20-30 kWh of electricity per ton of water evaporated, making them ideal for regions with high fuel or steam costs.
Under the European Union's Pressure Equipment Directive (PED 2014/68/EU), any vessel working above 0.5 bar pressure must carry a CE mark to verify safety compliance. Similarly, ASME U-stamp certification is a critical regulatory requirement for pressure vessels operating in North America. Jiangsu Zongheng maintains certified welding procedures, non-destructive testing (NDT) staff, and verified alloy raw material sourcing to ensure compliance with both European and American design codes.
For high-solids materials like corn fiber or spent grains, direct thermal drying is energy-intensive. A Single Screw Press uses mechanical pressure to squeeze out loose liquid before drying, reducing the moisture content of the wet cake from ~80% down to 55-60%. This significantly reduces the load on downstream drying systems (like a Tube Bundle Dryer or Airflow Dryer), resulting in lower fuel costs and smaller equipment sizes.
Fouling is minimized by keeping liquid velocities high, ensuring complete tube wetting, and scheduling routine Clean-in-Place (CIP) cycles. For high-scaling liquids, we recommend forced circulation systems, which use high-flow recirculating pumps to suppress boiling inside the tubes, preventing dry spots and scaling.
