Tokyo, as a global hub for technological innovation and precision manufacturing, has seen a significant shift in its industrial landscape. The demand for high-efficiency Falling Film Plate Evaporators has surged among Tokyo-based pharmaceutical, food processing, and chemical giants. As Japan pushes towards its "Society 5.0" goals, factories in the Greater Tokyo Area are increasingly adopting MVR (Mechanical Vapor Recompression) and plate-type falling film technologies to minimize their carbon footprint.
In the bustling industrial districts of Ota and Kawasaki, the integration of AI-driven monitoring with falling film evaporation systems is becoming the new standard. These systems are critical for the concentration of heat-sensitive materials, ensuring that the delicate chemical structures of products—ranging from amino acids to high-purity pharmaceutical ingredients—remain intact during the processing phase.
Jiangsu Zongheng Concentration & Drying Equipment Co., Ltd. (formerly Yixing Yangxi Light Industry Machinery Factory), founded in 1992, is located in Zhoutie Town, Yixing City. The company is a modern high-tech enterprise specializing in the manufacturing of concentration, drying, starch industry, alcohol DDGS, and Category III medium & low-pressure vessel equipment. It is currently a member enterprise of the China Starch and Alcohol Association. Its products are widely used in industries such as food fermentation, alcohol, chemical, pharmaceutical, environmental protection, and petrochemical.
⚙️Energy Efficiency & Decarbonization: With Tokyo's strict environmental regulations, local manufacturers are prioritizing Thermal Vapor Recompressors (TVR) and MVR systems. These technologies allow factories to recycle latent heat, drastically reducing steam consumption, which is a major cost factor in Japan's energy-intensive sectors.
🧪Bio-Technology Surge: The Chiba-Tokyo-Kanagawa life science corridor has increased the demand for sterile-grade falling film evaporators. These are used in the production of trehalose, erythritol, and various glucose derivatives where high purity and low residence time are non-negotiable.
♻️Wastewater Zero-Liquid Discharge (ZLD): Tokyo's metropolitan environmental policies encourage "Zero-Liquid Discharge." Our evaporators are now being integrated into high-salinity wastewater treatment plants across the Kanto region, converting industrial waste into reusable water and valuable solid byproducts.
🌐Smart Manufacturing: The localization of our equipment includes IoT-ready sensors that communicate directly with Tokyo factory management systems, allowing for real-time adjustments and predictive maintenance, ensuring 24/7 operational stability.
In March 2002, the company took the lead in obtaining ISO9001:2015 international quality system certification (Certificate No.: 45021). In July 2007, it became a Jiangsu Provincial High-Tech Enterprise. In April 2009, the company obtained the Special Equipment Manufacturing License of the People's Republic of China (License No.: TS2232C42). In August 2012, it acquired the ASME "U" Stamp authorization.




Our company's main products include Tube Bundle Dryers, with design and manufacturing capabilities reaching 1600m². We are a primary manufacturer of large-scale equipment including Single Screw Fiber & Germ Dehydrators and Wash Cyclones.
Our evaporation plants comprise Multi-Effect Evaporators, Thermal Vapor Recompressors (TVR), and Mechanical Vapor Recompressors (MVR). These are widely used for liquid concentration, including distillates, alcohol stillage, ammonium sulfate, corn steep liquor, itaconic acid, threonine, starch sugar, sorbitol, glucose, fructose, and high-salinity wastewater.
The company currently holds an absolutely leading position in evaporation technology and has extensive cooperation with many renowned large domestic and international group companies.












While meeting domestic market demand, our DDGS alcohol equipment and tube bundle dryer series products have been exported to Russia and Southeast Asian markets. We are capable of providing professional technical support and after-sales service nationwide for our vast user base. High-quality products and their unique solutions not only enhance our corporate economic benefits but also bring us satisfaction by solving processing challenges for our clients.
