Bulgaria, strategically located at the crossroads of Europe and Asia, has been experiencing a steady industrial transformation over the past decade. The country's chemical, pharmaceutical, and food processing sectors are undergoing significant modernization to meet stringent European Union (EU) environmental and energy efficiency standards. In this context, the demand for an advanced Automatic Chemical Evaporator Supplier & Service in Bulgaria has surged dramatically. Traditional evaporation methods, which are often energy-intensive and less precise, are rapidly being replaced by automated, high-efficiency systems.
The Bulgarian chemical industry, concentrated in regions like Devnya, Burgas, and Stara Zagora, heavily relies on processes such as liquid concentration, crystallization, and solvent recovery. Currently, local enterprises are facing immense pressure to reduce their carbon footprint and operational costs. This has created a robust market for sophisticated evaporation technologies, including Mechanical Vapor Recompression (MVR) and Thermal Vapor Recompression (TVR) systems. As a leading supplier, we recognize that Bulgarian industries require robust, reliable, and highly automated equipment capable of handling complex chemical compositions, high-salinity wastewater, and organic effluents with minimal energy consumption.
Jiangsu Zongheng Concentration & Drying Equipment Co., Ltd.
Jiangsu Zongheng Concentration & Drying Equipment Co., Ltd. (formerly Yixing Yangxi Light Industry Machinery Factory), founded in 1992, 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. As we expand our footprint globally, we are proud to offer premium Automatic Chemical Evaporator solutions tailored for the Bulgarian market. Our products are widely used in industries such as food fermentation, alcohol, chemical, pharmaceutical, environmental protection, and petrochemical.
The trajectory of industrial equipment in Bulgaria points firmly towards automation, digitalization, and sustainability. The trend of integrating AI and IoT (Internet of Things) into chemical evaporators is gaining unprecedented momentum. An Automatic Chemical Evaporator is no longer just a mechanical vessel; it is a smart system capable of real-time monitoring, predictive maintenance, and autonomous parameter adjustments. In Bulgaria, where skilled labor shortages can sometimes impact industrial operations, fully automated systems provide a crucial advantage by ensuring continuous, optimized production with minimal human intervention.
Furthermore, circular economy principles are heavily influencing purchasing decisions in Bulgaria. Industries are prioritizing Zero Liquid Discharge (ZLD) systems. Our Waste Heat Evaporators and MVR plants align perfectly with this trend by achieving minimal unit energy consumption. By recycling latent heat and significantly reducing steam dependency, these systems not only comply with EU environmental directives but also offer an impressive return on investment for Bulgarian manufacturers. The shift from traditional multi-effect evaporators to hybrid and MVR systems is expected to accelerate, driven by both regulatory frameworks and economic incentives.
Jiangsu Zongheng is always committed to exploration and innovation. Through years of sincere effort, we have achieved sustained development. Main products include evaporation plants, comprising Multi-Effect Evaporators, Thermal Vapor Recompressors (TVR), Waste Heat Evaporators, and Mechanical Vapor Recompressors (MVR). These are widely used for liquid concentration, including distillates, alcohol stillage, ammonium sulfate, corn steep liquor, organic wastewater, high-salinity wastewater, etc., making us an ideal partner for Bulgarian enterprises seeking technological upgrades.
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. 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.
We provide comprehensive solutions tailored to the specific needs of our clients. Whether it involves complex chemical recovery or straightforward wastewater volume reduction, our engineering team ensures that every piece of equipment operates at peak efficiency. The integration of our systems into existing Bulgarian infrastructure is seamless, backed by our dedicated technical support.
Bulgaria is world-renowned for its Rose Valley and the production of premium rose oil. The extraction processes generate significant amounts of aqueous by-products and organic wastewater. Utilizing an Automatic Chemical Evaporator, local producers can efficiently concentrate these effluents, recovering valuable secondary compounds and ensuring that the discharged water meets the strict ecological standards of the region. The gentle evaporation process ensures that heat-sensitive organic components are not destroyed.
The pharmaceutical sector is a major pillar of the Bulgarian economy. The production of Active Pharmaceutical Ingredients (APIs) requires rigorous solvent recovery and liquid concentration. Our MVR and TVR evaporators provide the high purity and sterile conditions necessary for pharmaceutical applications. By automating the evaporation process, Bulgarian pharma companies can achieve consistent batch quality, reduce the risk of contamination, and significantly lower their energy expenditures.
In regions producing wine, beer, and fermented dairy products, managing stillage and whey is a critical challenge. Our evaporation systems are extensively used for the concentration of alcohol stillage, starch sugar, glucose, and fructose. By implementing our technology, Bulgarian food processing plants can convert waste streams into valuable animal feed additives (like DDGS) or biogas substrates, thereby creating a closed-loop production cycle.
Industrial zones near the Black Sea coast deal with complex, high-salinity wastewater from petrochemical refining and heavy chemical synthesis. Our advanced Waste Heat Evaporators are designed to handle highly corrosive materials. By utilizing waste heat generated from other plant processes, these evaporators drastically reduce the volume of hazardous waste, facilitating easier disposal and compliance with international maritime and environmental regulations.
In March 2002, the company took the lead in obtaining ISO9001:2015 international quality system certification. In April 2009, we obtained the Special Equipment Manufacturing License, and in August 2012, we acquired the ASME "U" Stamp authorization. We possess strong R&D capabilities and advanced manufacturing processes, holding multiple innovative technology patents.














The company currently holds an absolutely leading position in evaporation technology and has extensive cooperation with many renowned large group companies. We are proud of the trust placed in us by our global and regional partners.





























While meeting domestic market demand, our DDGS alcohol equipment and tube bundle dryer series products have been exported globally, including to Russia, Southeast Asian markets, and increasingly across Eastern Europe. We are highly capable of providing professional technical support and after-sales service nationwide for our vast user base, ensuring that our Bulgarian clients receive prompt, efficient, and reliable assistance.
High-quality products and their unique solutions not only enhance our corporate economic benefits but also bring us immense satisfaction by solving complex processing challenges for our clients. We warmly welcome friends from various industries in Bulgaria and internationally to visit us for cooperation and mutual development. Together, we can build a more efficient and sustainable industrial future.
