Engineered for high performance, thermal efficiency, and compliance with California’s strict environmental and energy standards.
The San Francisco Bay Area is a global powerhouse of technological innovation, but it also hosts a highly sophisticated industrial ecosystem. From the pioneering biotechnology cluster in South San Francisco to the advanced food and beverage processing facilities in the East Bay, local enterprises face unique operating challenges. Chief among these is the critical need for sustainable, energy-efficient processing equipment that complies with California’s stringent environmental regulations.
Water conservation and Zero Liquid Discharge (ZLD) mandates are major drivers of operational strategy in Northern California. The state's strict Title 22 water reclamation standards and carbon reduction policies mean that traditional, energy-intensive waste treatment is no longer viable. This is where high-performance single evaporator systems become essential. By utilizing advanced thermal separation, businesses can recover up to 95% of process water, concentrate valuable by-products, and dramatically reduce waste disposal costs.
Our single evaporators, waste heat systems, and dewatering screw presses are custom-engineered to meet these exact needs. Whether you are recovering solvents in a pharmaceutical lab, processing steep liquors in a food facility, or treating complex industrial wastewater, we deliver factory-direct solutions that match the rigorous engineering standards of the San Francisco Bay Area.
Engineered to help San Francisco facilities meet strict local EPA, water district, and Zero Liquid Discharge (ZLD) regulations.
All pressure vessels are manufactured under strict ASME compliance, ensuring safety and seamless regulatory approval in CA.
Discover how modern thermal separation is adapting to digital automation, energy efficiency, and low-carbon mandates.
Modern evaporators serving the tech-savvy Bay Area utilize IoT sensors and PLC automation for real-time monitoring of heat transfer efficiency, fouling detection, and automated cleaning-in-place (CIP) cycles.
By pairing single-effect evaporators with Mechanical Vapor Recompression (MVR) or Thermal Vapor Recompression (TVR), we recycle latent steam heat, cutting utility energy consumption by up to 70%.
To withstand highly corrosive wastewater and acidic organic concentrates, our systems are built using premium materials like Titanium, Duplex Stainless Steel (2205/2507), and 316L Stainless Steel.
Jiangsu Zongheng Concentration & 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.

Our products are widely used in industries such as food fermentation, alcohol, chemical, pharmaceutical, environmental protection, and petrochemical.
By combining our massive manufacturing capacity in China with local engineering standards in the United States, we provide San Francisco industrial clients with premium, ASME-certified equipment at highly competitive factory-direct pricing, backed by reliable global logistics and support.
In March 2002, the company took the lead in obtaining ISO9001:2015 international quality system certification (Certificate No.: 45021), establishing a complete quality assurance system aligned with international standards. 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, marking the company's entry into a new phase of development. The company possesses strong R&D capabilities and advanced manufacturing processes, currently employing over 3 senior engineers and more than 20 engineers and assistant engineers. Multiple innovative technologies have been patented, and many products hold leading positions domestically.
The company's other main products include Tube Bundle Dryers, with design and manufacturing capabilities reaching 1600m² (making it a primary manufacturer of large tube bundle dryers). Other main products such as Single Screw Fiber & Germ Dehydrators and Wash Cyclones are recognized as high-quality products by starch manufacturers and the industry.
High-quality products and a sincere service attitude have won consistent praise and trust from numerous users at home and abroad, fully demonstrating the company's first-class technical advantages and manufacturing capabilities for large-scale equipment.
Jiangsu Zongheng is always committed to exploration and innovation. Through years of sincere effort and user support, it has achieved sustained development. Main products include evaporation plants, comprising Multi-Effect Evaporators, Thermal Vapor Recompressors (TVR), Waste Heat Evaporators, and Mechanical Vapor Recompressors (MVR, achieving minimal unit energy consumption).
These are widely used for liquid concentration, including distillates, alcohol stillage, ammonium sulfate, corn steep liquor, itaconic acid, threonine, starch sugar, sorbitol, glucose, fructose, trehalose, erythritol, organic wastewater, high-salinity wastewater, etc., making the company one of the domestic manufacturers with the most extensive product variety.
The company currently holds an absolutely leading position in evaporation technology and has extensive cooperation with many renowned large domestic group companies, including Zhuofeng Biology, Meihua Group, Yufeng Group, Yihai Kerry, North China Pharmaceutical Group, Harbin Pharmaceutical Group, Shouguang Juneng, Qilu Pharmaceutical, Qiyuan Pharmaceutical, Xiwang Group, Shengtai Biology, Zhejiang Huakang, Kelun Pharmaceutical (Yili), and Shandong Tianli.
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 (including the US West Coast and San Francisco Bay Area) 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. We warmly welcome friends from various industries, both domestic and international, to visit us for cooperation and mutual development!
