High-efficiency process systems certified to ASME, ISO, and CE regulations
Thermodynamic Optimization, Global Compliance, and System Integration in Process Engineering
The global process manufacturing sector is undergoing an unprecedented shift toward decarbonization, process automation, and thermal efficiency. Drying and concentration are energy-intensive unit operations. Industrial players are facing strict regulations on greenhouse gas emissions and rising energy prices, which has accelerated the transition from traditional, direct-fired steam processes to integrated energy-recovery systems.
Modern plants prioritize solutions that utilize low-grade waste heat, mechanical vapor recompression (MVR), and advanced control loops. High-speed airflow drying systems, falling film evaporators, and tube bundle dryers must now provide high performance with minimal environmental impact. Our commitment as a CE-certified manufacturer is to bridge the gap between heavy thermodynamic loads and low energy consumption, ensuring that our systems deliver high productivity while maintaining a low carbon footprint.
Mechanical Vapor Recompression replaces traditional boiler steam by compressing and recycling process vapors, achieving up to 90% energy savings compared to single-effect evaporators.
Leveraging waste heat from dryers to preheat evaporation feed liquids decreases total plant fuel requirements and optimizes the primary energy consumption index.
Global operations mandate adherence to international standards. Explosion-proof designs (ATEX/IECEx) and pressure vessel codes (ASME U-stamp, CE-PED) are non-negotiable.
International procurement departments face complex challenges when choosing equipment manufacturers. They look for suppliers who can manage the entire process, including initial thermodynamic modeling, mechanical manufacturing, and global shipping logistics. These projects require a clear technical roadmap that ensures high efficiency, ease of operation, and long-term durability under harsh operational conditions.
Detailed performance parameters of our main product lines
Designed for rapid, convective drying of wet powders, filter cakes, and granular materials. This system utilizes a high-velocity stream of hot air to fluidize and transport wet solids through a series of drying ducts with varying diameters.
Engineered to concentrate highly heat-sensitive fluids, including fruit juices, dairy products, chemical additives, and industrial wastewater. This system ensures a short contact time and low operating temperatures, protecting the product from thermal degradation.

Jiangsu Zongheng operates with a clear commitment to technical quality and international compliance. Pressure vessels are critical process components that require careful design, structural testing, and certified safety parameters. Our engineering department uses advanced software to perform finite element analysis (FEA) and thermodynamic calculations, ensuring that our systems deliver reliable service over decades of operation.
Our regulatory roadmap ensures that all machinery exported to Europe and global markets meets local standards:
For large-scale process plant engineering, the equipment delivery is just the first step. Jiangsu Zongheng provides comprehensive services from installation supervision and mechanical assembly guidance to hot commissioning and operator training. We collaborate with local engineering companies globally to ensure quick access to spare parts, rapid maintenance, and on-site support. Our engineers can travel to customer facilities to assist during critical startup phases, helping to optimize system performance and ensure long-term operational success.
Key information regarding compliance, efficiency, and engineering parameters
Pressure components must comply with the Pressure Equipment Directive (PED) 2014/68/EU. Electrical systems, controls, and rotating elements are certified under the Machinery Directive 2006/42/EC and the Low Voltage Directive 2014/35/EU. Our systems are built and tested to meet all of these European directives, ensuring safe operation and compliance.
Mechanical Vapor Recompression (MVR) utilizes a centrifugal compressor or blower to raise the pressure and temperature of the vapor generated in the evaporator. The compressed vapor is then recycled to heat the same effect, which significantly reduces the need for primary steam. The main energy input is electricity for the compressor, resulting in up to 90% energy savings compared to single-effect steam systems.
Yes. Jiangsu Zongheng received the ASME U-Stamp authorization in 2012. We design and manufacture Category III medium and low-pressure vessels in strict compliance with ASME Section VIII Division 1 guidelines, utilizing qualified welders and certified materials.
We construct our starch washing cyclones, degerming mills, and dryer piping from premium stainless steel grades such as SS304 and SS316L. Where high wear and corrosion resistance are needed, we use duplex stainless steels (such as 2205) and apply surface hardening treatments to extend the service life of critical parts.
Our falling film evaporators use custom-designed liquid distribution plates situated at the top of the tube bundle. This setup ensures that the feed liquid is distributed evenly as a uniform film down the inner tube walls, avoiding dry spots, minimizing fouling, and maintaining high heat transfer rates.
