Read MoreFounded in 1992 (originally known as Yixing Yangxi Light Industry Machinery Factory), Jiangsu Zongheng Concentrating and Drying Equipment Co., Ltd. is nestled in Zhoutie Town, Yixing City, alongside the scenic Taihu Lake. Over the span of three decades, our campus has expanded to encompass more than 54,000 square meters of high-end manufacturing space, with modern production workshops occupying over 22,000 square meters.
As a recognized high-tech enterprise and standing member of the China Starch and Alcohol Association, we dedicate our research and fabrication prowess to evaporation systems, starch processing structures, DDGS dryers, and Class III medium/low-pressure vessel manufacturing. Our equipment is relied upon globally across the food fermentation, starch, chemical, pharmaceutical, and wastewater-treatment industries.
From titanium and duplex steel structural options to specialized fouling prevention configurations, we optimize industrial systems based on fluid composition, solid dynamics, and energetic parameters.
An in-depth review of thermal separation technologies, engineering methodologies, energy efficiencies, and industrial deployment parameters.
Mechanical Vapor Recompression (MVR) processes utilize a compressor (radial blower or turbo-compressor) to increase the enthalpy and temperature of the generated clean water vapors. By recycling this steam back into the primary heating side, boiler usage is minimized to startup cycles, yielding thermal efficiencies up to 90% higher than classic multi-effect setups.
Optimized for heat-sensitive streams, falling film evaporators introduce liquid feed at the tube bundle's apex. Leveraging gravity and advanced distributor trays, the liquid travels downward as a thin film along the inner tube walls. Vapor and liquid flow concurrently, guaranteeing minimal residence times and preventing degradation of active ingredients.
Designed for crystallization, high viscosities, and streams prone to scaling. Reaching high recirculation velocities inside the exchanger pipes prevents premature boiling inside the tubes. Vaporization only occurs inside the separator chamber, drastically reducing structural fouling rates and extending runtime windows.
In contemporary bio-refining and chemical processing facilities, thermal efficiency dictates commercial survival. Jiangsu Zongheng's Waste Heat Evaporator systems operate by integrating low-grade secondary energy streams. By collecting drying exhaust air, low-pressure flash vapor, and residual boiler condensate, the evaporator serves as a thermodynamic heat pump. Instead of relying on fresh live steam, the heat demand is fulfilled through waste energy integration. This multi-effect structure reduces overall plant utility consumption, helping operations align with global decarbonization targets.
Industrial liquids are rarely simple solutions. They often contain chlorides, organic acids, and suspended silicates. Our manufacturing facility utilizes high-grade materials to prevent premature stress-corrosion cracking and erosion:
Established as Yixing Yangxi Light Industrial Machinery Factory, covering a modest area of approximately 15 mu with 45 dedicated employees.
Pioneered standardized production control by obtaining ISO9001 certification, standardizing manufacturing quality checks.
Formally recognized as a High-Tech Enterprise by the government, marking key investments in thermal engineering R&D.
Obtained the Special Equipment Manufacturing License of the PRC (License No.: TS2232C42) for regulated pressure vessel construction.
Acquired the ASME "U" Stamp authorization, validating pressure vessel engineering for export to American and international markets.
Secured global-grade quality system credentials (Certificate No.: 45021), establishing a complete quality assurance system aligned with international standards.
Operating a 54,000+ m² facility, featuring 3 senior engineering directors, 20+ engineering personnel, and over 120 skilled technicians.
How our custom systems adapt to regional parameters, input variances, and local regulations.

Yixing is the heart of China’s stainless steel and pressure vessel manufacturing ecosystem. Building industrial equipment at our facility offers key cost and quality advantages:
This vertical integration ensures rapid project execution times and cost efficiencies, while matching the engineering standards of global manufacturers.
Designing next-generation multi-effect configurations that pair MVR technology with solar thermal collectors and industrial heat pump networks, aiming for net-zero carbon footprints.
Integrating smart sensors that track real-time changes in the overall heat transfer coefficient (U-value). This alerts operators to fouling before it impacts throughput, helping plan maintenance cycles.
Applying hydrophobic, ultra-smooth alloy coatings to heat exchanger tubes. This prevents scale adhesion and maintains design efficiency over longer operating periods.
