Optimized separation and concentration solutions tailored for Iberian industrial operations
Meeting European environmental directives through energy-efficient Chinese engineering
Portugal's manufacturing and processing sectors are undergoing a significant transition toward sustainability, driven by the European Green Deal and national initiatives like the "Portugal 2030" strategy. Key regions such as the industrial belts of Porto, Aveiro, Lisbon, and the chemical complexes of Sines and Estarreja are prioritizing green manufacturing. Industries ranging from pulp and paper, textiles, food processing (particularly tomato paste, olive oil, and wine distilleries), to fine chemicals and pharmaceuticals require robust, energy-efficient thermal separation technologies.
In this context, Single-Effect Evaporators play a vital role. They serve as cost-effective, highly reliable units for product concentration, solvent recovery, and wastewater volume reduction. For small to medium enterprises (SMEs) in Portugal, a single-effect evaporator offers a lower initial capital investment compared to complex multi-effect systems, while delivering the precise thermal control needed for delicate or heat-sensitive products.
Portugal is a global leader in tomato paste and olive oil production. Single-effect evaporators are widely used for concentrating juices, purees, and agricultural extracts, preserving natural flavors and nutritional profiles.
In regions like the Douro Valley and Alentejo, processing wine waste and distillery spent wash is crucial. Our systems concentrate vinasses, facilitating byproduct recovery for animal feed or fertilizer.
Supporting Zero Liquid Discharge (ZLD) systems in Lisbon and Sines chemical parks. Evaporators concentrate high-salinity industrial wastewater, recovering pure distillate for reuse.
Jiangsu Zongheng Concentration & Drying Equipment Co., Ltd. (formerly Yixing Yangxi Light Industry Machinery Factory)
Founded in 1992, Jiangsu Zongheng 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.
Jiangsu Zongheng 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. Our products are widely used in industries such as food fermentation, alcohol, chemical, pharmaceutical, environmental protection, and petrochemical.
Advanced fabrication of large-scale thermal processing equipment.
With rising energy prices across the Iberian Peninsula, Portuguese manufacturers are shifting from traditional thermal evaporation to highly integrated energy-saving configurations. Jiangsu Zongheng addresses this need by offering hybrid systems that combine Single-Effect Evaporators with advanced energy recovery technologies.
By incorporating Thermal Vapor Recompressors (TVR) or Mechanical Vapor Recompressors (MVR), we significantly lower the live steam consumption. Furthermore, utilizing industrial waste heat (such as flue gas or low-pressure condensate) allows Portuguese factories to run evaporation processes at minimal utility costs.
Our product lineup also features advanced Tube Bundle Dryers (with design and manufacturing capabilities reaching 1600m²), Single Screw Fiber & Germ Dehydrators, and Wash Cyclones. These auxiliary solid-liquid separation solutions ensure that solid-containing effluents are optimally dewatered before entering the evaporator, maximizing overall system uptime and efficiency.
Energy Saving Insight for Portugal: Integrating a TVR system with a Single-Effect Evaporator can reduce steam consumption by up to 50%, making it highly suited for the cost-sensitive Portuguese agro-industrial sector.
Our custom-engineered evaporation plants are designed to handle a broad spectrum of industrial liquids, including:
Ensuring absolute safety, quality, and pressure vessel standards for European deployment
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.
Cooperating with industry leaders to deliver world-class evaporation and drying systems
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, the company's 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.
For our clients in Portugal, we offer comprehensive project lifecycle services. This includes initial thermal and mechanical design using state-of-the-art simulation software, manufacturing of pressure vessels in compliance with strict international codes (including ASME and European CE equivalents), shipping logistics, on-site installation guidance, and remote commissioning support. Our engineering team is dedicated to customizing evaporator configurations specifically for the process parameters, temperature sensitivities, and energy sources available at your plant in Portugal.
