Explore our leading-edge industrial solutions designed for maximum thermal efficiency, low emissions, and robust operational stability.
In modern industrial thermal management, glycol evaporators serve as critical nodes in heat transfer networks. By utilizing ethylene or propylene glycol mixtures, these systems prevent freezing in low-temperature environments while maintaining high heat transfer coefficients. Globally, the demand for high-efficiency glycol evaporators is surging, driven by the rapid expansion of cold chain logistics, pharmaceutical processing, food fermentation, and large-scale chemical synthesis.
As environmental regulations tighten and carbon neutrality targets become legally binding across North America, Europe, and Asia-Pacific, traditional thermal concentration systems are undergoing a paradigm shift. Modern engineering demands systems that not only deliver precise temperature control but also minimize energy consumption. Glycol-based heat exchange loops are increasingly integrated with advanced technologies like Mechanical Vapor Recompression (MVR) and multi-effect falling film systems to achieve optimal thermodynamic cycles.
Decades of manufacturing excellence and engineering capacity on a global scale.
Our comprehensive suite of concentration, drying, and separation equipment is engineered to meet the stringent demands of modern heavy industries.
Our falling film evaporators efficiently concentrate 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.
Jiangsu Zongheng's single screw press efficiently dewaters solid-containing slurries, fibers, and organic residues. By utilizing a progressive pitch screw design, the system exerts high mechanical pressure to separate liquid phases from solids, significantly reducing subsequent thermal drying costs.
Designed for continuous drying of heavy bulk materials, our ZXG Tube Bundle Dryers ensure safe, low-oxygen drying via indirect steam heating. The rotating tube bundle passes through the stationary material bed, providing high heat transfer rates with minimal mechanical wear.
Jiangsu Zongheng's MQG Airflow Dryer employs high-speed hot air to suspend and fluidize wet materials. By utilizing impulse airflow generated from precisely varied tube diameters, it continuously tumbles particles while conveying them. This design ensures rapid, uniform, and efficient drying throughout the entire transportation process within the system.
For precision maize processing, our degerming mills ensure clean germ separation while preserving kernel integrity. Paired with the YDX Starch Washing Cyclone, which utilizes multi-stage hydrocyclone technology, the system achieves maximum starch refining, protein separation, and purity improvement.
