Evaluating Falling Film, Forced Circulation, and Mechanical Vapor Recompression (MVR) technologies.
A falling film evaporator distributes the feed liquid as a thin film flowing down the inside of vertical tubes. Evaporation occurs under vacuum, reducing the boiling point and ensuring a short residence time. This layout preserves the nutritional, chemical, or biological profiles of heat-sensitive liquids like corn steep liquor (CSL) and dairy concentrates.
Designed to handle high viscosity and heavy scaling tendencies. High-velocity axial flow pumps recirculate the liquor through the heat exchanger tubes, suppressing boiling inside the tubes by maintaining hydrostatic head. Boiling occurs only when the fluid enters the flash vessel separator.
Mechanical Vapor Recompression (MVR) utilizes a centrifugal compressor or fan blower to compress the low-pressure vapor rising from the evaporation chamber. This compression elevates the vapor's temperature and enthalpy, allowing it to act as the heating medium for the same effect.
Preserving our core product line definitions and specialized process descriptions.
Zongheng provides energy-efficient, high-performance evaporation solutions configured to match the unique chemical properties of your process media.
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.
Zongheng is a premier Chinese manufacturer specializing in forced circulation evaporators. We employ high-capacity recirculation pumps to combat extreme fouling, crystallization, and viscosity scaling.
Mechanical Vapor Recompression (MVR) plants offer significant operational savings by reusing latent heat from evaporated vapor, reducing steam boiler demands.
This design integrates multiple waste heat sources—including drying vapors, boiler flue gas, or process condensate—into a cohesive unit that dramatically cuts energy inputs.
Jiangsu Zongheng's single screw press efficiently dewaters solid-containing slurries, fibers, and starch residues, preparation-rich pulps, and industrial wastes, optimizing downstream dryer performance.
Jiangsu Zongheng's ZXG Tube Bundle Dryers ensure safe, low-oxygen drying via indirect steam-heated tubes revolving slowly inside a stationary housing. Perfect for corn gluten and DDGS drying.
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.
Zongheng's degerming mills ensure precision germ removal, preserving kernel structure while cleanly separating starch and fiber components in modern dry/wet corn mills.
Jiangsu Zongheng's YDX Starch Washing Cyclone is specifically engineered for the multi-stage counter-current purification and refining of high-grade corn, cassava, or potato starch.
From a local machinery factory to a global high-tech concentration and drying equipment manufacturer.

How our integrated evaporators, presses, and dryers optimize downstream yields across industries.
In corn wet milling, corn steep liquor (CSL) contains high concentrations of proteins and amino acids. Evaporating water from CSL creates a valuable nutrient concentrate used in animal feed or fermentation media.
By utilizing our Single Screw Press to dewater corn fiber and germ, and concentrating the steep liquor in our Falling Film Evaporation Plant, plants reduce the load on their rotary dryers. This decreases energy consumption and increases protein recovery rates.
Alcoholic wastewater and thin stillage concentration is critical for DDGS (Distillers Dried Grains with Solubles) production. Concentrating thin stillage to syrup (usually 30-40% solids) via waste heat evaporators saves significant energy before it is mixed with wet grains and dried.
Jiangsu Zongheng integrates multi-effect configurations that utilize stripper exhaust vapors or steam dryer condensate flash steam as thermal input, lowering the energy required per ton of evaporated water.
Protecting operations from corrosion, chloride-induced stress cracking, and dynamic mechanical fatigue.
Industrial wastewater often contains organic acids and chloride ions. We fabricate heat transfer tubes using Grade 304, 316L, Duplex Stainless Steel (2205), and Titanium (TA2) to prevent localized pitting and extend equipment life under high temperatures.
Our ASME IX-certified welders perform automatic TIG/orbital welding on tubesheets. Weld seams undergo Non-Destructive Testing (NDT), including radiographic, ultrasonic, and dye penetrant inspection, to comply with PED 2014/68/EU guidelines.
Modern systems feature Siemens PCS7 / DeltaV DCS platforms. Algorithms track real-time boiling points, adjust feed rates to maintain film thickness, regulate compressor speeds, and trigger automatic Clean-In-Place (CIP) cycles when heat transfer rates drop.
