Select industrial systems manufactured to stringent CE and ISO standards.
Maximizing thermal efficiency, recovery rates, and process safety in chemical production.
Industrial concentration and chemical processing require high-performance, resilient thermal separation technologies. Industrial chemical evaporators perform critical roles across processes such as crystallization, concentration, volume reduction, and Zero Liquid Discharge (ZLD) wastewater treatment. High-efficiency systems ensure maximum water reclamation and solute concentration while minimizing heat consumption.
Our CE-certified evaporators utilize advanced thermal dynamic processes. By matching the boiling points of solvents under vacuum conditions with exact steam compression configurations, we achieve high energy efficiency. Chemical plants can dramatically cut operating costs (OPEX) by selecting the optimal system architecture—whether it is Mechanical Vapor Recompression (MVR), Multiple-Effect Evaporation (MEE), or Forced Circulation systems.
Our chemical evaporators are meticulously engineered to handle aggressive corrosive elements, high-viscosity media, and heat-sensitive organic compounds. Incorporating high-grade metallurgy including Titanium (Gr. 1, Gr. 2), Hastelloy, Duplex Stainless Steel (2205, 2507), and SUS316L prevents pitting and stress-corrosion cracking.
Integrated chemical engineering architectures from starch refining to complex wastewater purification.
Process effluent and mother liquor streams demand robust volume-reduction and crystallization processes. Our Forced Circulation Evaporators and MVR units yield pure condensate water ready for reuse while crystallizing inorganic salts for easy separation and disposal, achieving true Zero Liquid Discharge.
Specifically designed for the concentration of corn steep liquor, starch washing lines, glucose syrups, and organic acid streams. By utilizing low-temperature Falling Film plants, we protect thermal-sensitive nutrients and prevent product degradation during the concentration cycle.
Reclaiming thin stillage in distilleries requires massive energy inputs. Our multi-effect and waste heat evaporators integrate directly with drying systems (such as our ZXG Tube Bundle Dryers) to leverage secondary steam, reducing overall thermal consumption by up to 45% compared to baseline configurations.
Original engineering briefs for our core operational machinery.
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.
Jiangsu Zongheng Concentrating and Drying Equipment Co., Ltd is situated in the industrial center of Zhoutie Town, Yixing City, on the shores of Taihu Lake. Since 1992, Yixing has served as a center for process machinery, offering a robust supply chain, raw material integration, and high engineering standards.
Our production facilities benefit from localized access to premium stainless steel refineries, advanced CNC machining vendors, and testing institutes. This structural layout allows us to deliver high-performance evaporators and dryers with a lower total cost of ownership (TCO) than Western suppliers, without compromising build quality, material thickness, or international safety compliance.
