Explore our core manufacturing capabilities, spanning high-efficiency airflow dryers, starch cyclones, degerming mills, and multi-effect evaporation plants.
In modern heavy industries, thermal processing is a cornerstone of operational efficiency. Global procurement teams in sectors such as corn wet milling, bio-ethanol production, starch processing, and chemical synthesis face escalating challenges. The demand is no longer just for standard drying equipment, but for highly engineered, thermodynamically optimized thermal transfer systems that minimize energy consumption while maximizing output quality.
Dryer tubes and tube bundles represent the critical heat exchange interface in these systems. A minor failure in tube integrity or thermal distribution can lead to catastrophic downtime, costing processing plants hundreds of thousands of dollars per day. Consequently, procurement strategies have shifted toward manufacturers who can offer rigorous material traceability, ASME-compliant engineering, and proven structural longevity.
As a leading China Dryer Tube Supplier, Jiangsu Zongheng addresses these global pain points by integrating advanced metallurgy, precise mechanical tolerances, and customized thermal designs. We provide turnkey solutions that mitigate thermal stress, resist abrasive wear, and prevent chemical corrosion under continuous, high-load industrial environments.
Optimized steam distribution networks within the tube bundle to maximize heat transfer rates and reduce steam consumption.
ASME "U" stamp compliance ensuring pressure vessels withstand extreme operational parameters without deformation.
Utilization of high-grade stainless steels (304, 316L, duplex steels) tailored to the chemical profile of the processed media.
Proprietary tube-to-tubesheet welding techniques that eliminate stress concentration points and prevent joint leakage.
In starch processing, moisture reduction must be rapid yet gentle to prevent gelatinization. Our ZXG Tube Bundle Dryers utilize indirect steam heating, providing a controlled, low-oxygen environment that preserves starch properties. Combined with our YDX Starch Washing Cyclones, we deliver a complete refining loop that maximizes yield and purity.
Drying Distillers Dried Grains with Solubles (DDGS) requires handling highly viscous, heat-sensitive materials. Our integrated evaporation and drying systems combine MVR (Mechanical Vapor Recompression) Evaporators with high-capacity tube bundle dryers to concentrate thin stillage and dry the wet cake efficiently, significantly lowering the carbon footprint of bio-refineries.
Zero Liquid Discharge (ZLD) initiatives demand robust concentration technologies. Our Forced Circulation Evaporation Plants and Waste Heat Evaporators are engineered to handle high-fouling wastewater streams, recovering clean condensate and minimizing solid waste volume through thermal concentration.
Jiangsu Zongheng is actively researching and deploying advanced technologies to align with global decarbonization goals and Industry 4.0 standards:
Utilizing Computational Fluid Dynamics (CFD) and Finite Element Analysis (FEA) to simulate heat transfer and stress distribution, optimizing tube geometry before fabrication.
Integrating IoT sensors within the dryer housing to monitor tube wall temperatures, vibration, and steam pressure in real-time, enabling predictive maintenance.
Developing nano-composite, anti-fouling coatings for the exterior of dryer tubes to reduce material adhesion, minimize cleaning cycles, and maintain high thermal efficiency.

Jiangsu Zongheng Concentrating and Drying Equipment Co., Ltd, formerly known as Yixing Yangxi Light Industrial Machinery Factory, was established in 1992. The company covers a total area of approximately 15 mu and has a total of 45 employees.
Our thermal systems are deployed globally, delivering consistent performance across agricultural processing, chemical manufacturing, and environmental engineering sectors.
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.
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.
Our manufacturing processes are certified by leading international bodies, ensuring that every dryer tube and pressure vessel we produce complies with the strict safety and quality standards of your local market.
Holding the ASME "U" Stamp and CE certifications allows us to export seamlessly to North America, Europe, and beyond. Every pressure vessel undergoes rigorous non-destructive testing (NDT), including radiographic and ultrasonic inspections, to guarantee structural integrity under high pressure and temperature conditions.
We offer comprehensive logistical support, including custom packaging for ocean freight to prevent corrosion during transit. Our engineering team provides remote and on-site installation guidance, commissioning support, and scheduled maintenance training to ensure your system operates at peak efficiency from day one.
