Read MoreJiangsu Zongheng Concentrating and Drying Equipment Co., Ltd. (formerly Yixing Yangxi Light Industry Machinery Factory), founded in 1992, is located in Zhoutie Town, Yixing City, on the shores of the beautiful Taihu Lake. The company covers an area of over 54,000 square meters, with a production workshop area of over 22,000 square meters.
As a modern high-tech enterprise, we specialize in the engineering, design, and manufacturing of concentration, drying, starch industry, alcohol DDGS, and Category III medium & low-pressure vessel equipment. We are a proud member of the China Starch and Alcohol Association, serving global clients across food fermentation, chemical, pharmaceutical, environmental protection, and petrochemical industries.
Mechanical Vapor Recompression (MVR) represents the pinnacle of modern thermal concentration technology. By utilizing a centrifugal compressor or Roots blower, MVR systems compress the secondary vapor generated during the evaporation process. This compression increases both the pressure and temperature of the vapor, allowing it to be recycled back into the system as the primary heating medium.
Our technical roadmap focuses on optimizing the Specific Energy Consumption (SEC) and maximizing the Coefficient of Performance (COP). By integrating advanced CFD (Computational Fluid Dynamics) modeling, we design falling film and forced circulation evaporators that operate at minimal temperature differences (ΔT of 3°C to 6°C), preventing product degradation and scaling while maximizing heat transfer coefficients.
The next generation of Jiangsu Zongheng MVR systems incorporates IoT sensors and predictive maintenance algorithms. By continuously monitoring vibration profiles of the high-speed turbo compressors, heat exchanger fouling rates, and liquid distribution patterns, our smart control systems prevent unscheduled downtime.
Furthermore, we are actively developing hybrid systems that combine MVR with membrane filtration (such as Reverse Osmosis) and Waste Heat Recovery units. This holistic approach enables Zero Liquid Discharge (ZLD) for chemical and pharmaceutical plants, aligning with global environmental regulations and corporate ESG goals.
Integrating starch washing cyclones, degerming mills, and single screw presses to optimize starch extraction and dewatering. Our waste heat evaporators concentrate corn steep liquor (CSL) efficiently, turning waste streams into valuable animal feed byproducts.
Complete concentration and drying lines for Distillers Dried Grains with Solubles (DDGS). By pairing our multi-effect or MVR evaporators with high-capacity tube bundle dryers, we ensure low-temperature drying that preserves nutritional value.
Treating high-salinity industrial wastewater from petrochemical, pharmaceutical, and electroplating facilities. Our forced circulation MVR crystallizers handle high-fouling liquids, recovering pure water and solid salts.
Located in Yixing, the heart of China's industrial machinery manufacturing cluster, Jiangsu Zongheng leverages a highly integrated local supply chain. This geographical advantage allows us to source premium raw materials, such as duplex stainless steel (SAF 2205, SAF 2507) and titanium alloys, at competitive rates with minimal lead times.
Our production workshops are equipped with heavy-duty rolling machines, automatic plasma welding systems, and state-of-the-art non-destructive testing (NDT) equipment. By maintaining strict control over every step of the fabrication process—from design and material verification to welding, assembly, and pressure testing—we guarantee the structural integrity and longevity of our pressure vessels.
Established as Yixing Yangxi Light Industrial Machinery Factory, starting with a team of 45 employees and a focus on local industrial machinery fabrication.
Obtained ISO9001 International Quality Management System certification, standardizing manufacturing and quality control workflows.
Recognized as a Jiangsu Provincial High-Tech Enterprise, accelerating R&D in energy-efficient concentration technologies.
Acquired the Special Equipment Manufacturing License of the People's Republic of China (License No.: TS2232C42) for pressure vessel fabrication.
Acquired the prestigious ASME "U" Stamp authorization, marking our entry into the global high-end process equipment market.
Obtained international quality system certification (Certificate No.: 45021), aligning our quality assurance system with global standards.
Today, the company covers over 54,000 m² with a modern production workshop exceeding 22,000 m², employing senior engineers and serving global markets.
Our engineering team is fully versed in international design codes, including ASME Section VIII Div. 1, CE-PED, and Chinese GB150 standards. We provide complete documentation, material trace reports, and third-party inspection certificates required for global customs clearance and local plant commissioning.
We offer comprehensive site services, including installation supervision, cold/hot commissioning, and operator training. By partnering with local engineering firms worldwide, we ensure rapid response times for maintenance, spare parts delivery, and emergency support.
Every industrial process is unique. We do not believe in one-size-fits-all solutions. Our process engineers perform detailed mass and energy balances based on your specific feed liquid properties, optimizing heat exchanger surface areas and vapor compressor selections.
