Our key high-efficiency equipment configuration, precision-manufactured under rigid ISO 9001 and CE frameworks to ensure optimal thermal performance and energy containment.
In modern industrial processing, water management, product recovery, and waste reduction represent critical cost centers. Dewatering equipment, high-efficiency evaporators, and advanced separation technologies act as the mechanical heart of industries spanning food fermentation, bio-ethanol (DDGS), starch processing, chemicals, and industrial wastewater treatment. Globally, operators face dual pressures: lowering energy usage to meet carbon neutrality targets and maintaining consistent product yield and quality under strict regulatory regimes.
Compliance with international standards, particularly European CE Certification and the American Society of Mechanical Engineers (ASME) standards, is no longer optional. It serves as a seal of build quality, structural integrity under high pressure, and reliable mechanical operation. Finding high-capacity manufacturers with vertically integrated supply chains and rigorous certified testing is essential to minimizing operational downtime.
Our engineered systems focus on maximizing thermodynamic conservation and mechanical separation efficiency, converting raw materials into highly concentrated and stable products.
MVR systems recover latent heat from secondary vapors through mechanical compression. By reusing this compressed vapor as the heating source, steam consumption is slashed by up to 90%, representing the pinnacle of green industrial concentration.
Engineered for heat-sensitive liquids. The product forms a uniform thin film down vertical tube interiors, maximizing thermal transfer rates with minimal product residence time, preventing thermal degradation and scale formation.
Designed for physical, continuous dewatering of corn fiber, starch mash, and agricultural residuals. High torque combined with a decreasing screw pitch forces water out through robust cylindrical wedge wire screens.
Suspends particulates in high-velocity hot air streams. As the material travels through varying pipe diameters, impulse turbulence continuously breaks down boundary layers, delivering bone-dry particles in seconds.
Features a rotating steam-heated tube bundle encased in a stationary housing. Highly efficient contact drying for heavy organic solids like germ, fiber, and gluten meal, utilizing counter-current airflow for moisture sweep.
Centrifugal hydrocyclone manifolds arranged in series to refine, wash, and purify starch solutions. Removes trace proteins, fibers, and soluble impurities through highly precise fluid dynamics.
Explore the functional architecture of our core process equipment designed and built at our modern manufacturing base.
Jiangsu Zongheng's MQG Airflow Dryer employs high-speed hot air to suspend and fluidize the material. By utilizing impulse airflow generated from precisely varied tube diameters, it continuously tumbles the particles while conveying them. This design ensures rapid, uniform, and efficient drying throughout the entire transportation process within the system.
Particularly suited for processing light starches, proteins, and chemical additives where color retention, minimal heat exposure, and high output moisture stability are non-negotiable parameters.
A falling film evaporator efficiently concentrates heat-sensitive liquids. The feed liquid forms a thin film flowing down heated vertical tubes, where it partially evaporates. Vapor generated flows parallel to the liquid, enhancing the process. It ensures a short residence time and low operating temperature, preserving product quality. The system requires proper liquid distribution and complete surface wetting to prevent fouling and maintain high thermal efficiency and operational stability.
Widely utilized in dairy concentration, herbal extraction, and pharmaceutical processes where delicate molecular chains must remain completely undamaged.
Our engineering configurations are fine-tuned to align with regional industrial conditions, climate parameters, and environmental regulations globally.
In highly regulated EU states, dewatering systems must comply with strict wastewater directive standards and the circular economy mandate. Our CE-marked MVR evaporators and single screw presses are deployed here to achieve zero-liquid-discharge, allowing food processing and chemical factories to reclaim over 95% of process water while reducing carbon footprints via mechanical energy recycling rather than fossil-fuel steam generation.
Operating under large-scale continuous configurations, American agricultural processing plants require rugged, heavy-duty equipment. Our ASME "U" Stamp certified Tube Bundle Dryers and high-torque Single Screw Presses process thousands of tons of corn germ, corn fiber, and distillery spend grains (DDGS) daily, surviving harsh midwest winters and demanding continuous operational regimes.
Dealing with root crops like tapioca (cassava) in high-humidity tropical climates requires highly localized drying air dynamics. Our customized MQG Airflow Dryers feature automated hot-air humidity monitoring and compensation to prevent powder clumping and product denaturation, ensuring consistent bulk powder output even in humid monsoonal regions.
Jiangsu Zongheng operates from the industrial heart of China’s advanced machinery cluster in Yixing. Our local supply chain integration allows us to procure high-grade structural alloys, precision instrumentation, and heavy forging assets rapidly and cost-effectively.
By executing all steps—from metallurgical testing, raw vessel rolling, robotic welding, to full pressure testing and ASME/CE certification—under a single 22,000 square meter production workshop, we mitigate the risk of supply chain disruptions. This structural advantage translates directly to shorter lead times, lower transport footprints, and consistent quality assurance for global plant operators.
