Explore SolutionIn modern industrial process engineering, the concentration of highly viscous, fouling-prone, or crystallizing solutions represents a significant operational challenge. Traditional falling film or rising film evaporators often fail under these conditions due to rapid scaling, localized overheating, and subsequent tube blockage. The Multi-Effect Forced Circulation Evaporator stands as the definitive technological solution to these challenges, combining robust fluid dynamics with optimized thermodynamic efficiency.
The "Multi-Effect" configuration leverages the latent heat of vaporization across successive stages (effects) operating at progressively lower pressures and boiling points. The vapor generated in the first effect serves as the heating medium for the second effect, and so on. This cascading thermal design dramatically reduces steam consumption. For example, a triple-effect system typically consumes only about 0.35 to 0.4 tons of live steam per ton of water evaporated, compared to nearly 1.0 ton in a single-effect system.
Jiangsu Zongheng integrates advanced modeling software to calculate the exact boiling point elevation (BPE) of complex mixtures, ensuring the optimal number of effects is selected to balance capital expenditure (CAPEX) and operational expenditure (OPEX).
From Falling Film Evaporation Plants designed for heat-sensitive liquids to high-performance MVR (Mechanical Vapor Recompression) and Forced Circulation systems. We provide custom-engineered solutions that maximize heat transfer coefficients while minimizing energy footprints.
Jiangsu Zongheng's single screw press is specifically engineered to handle solid-containing materials, offering highly efficient mechanical dewatering prior to thermal drying, reducing overall process energy consumption.
Utilizing indirect steam heating, our tube bundle dryers provide a safe, low-oxygen environment for drying bulk materials. The continuous tumbling action ensures uniform moisture removal and prevents product degradation.
Our industrial airflow dryers employ high-speed hot air streams to suspend and fluidize damp materials. By varying tube diameters, we generate impulse airflow that continuously tumbles particles during transport, achieving rapid and uniform drying.
Engineered for precision germ removal in corn wet milling plants. Our degerming mills preserve kernel integrity while maximizing starch yield and germ separation efficiency.
Specifically designed for starch refining and purification. Our multi-stage cyclone systems deliver precise separation of starch, proteins, and soluble impurities, ensuring high-grade final products.
As global industries transition toward carbon neutrality and zero-emission mandates, the design of thermal separation systems must evolve. Jiangsu Zongheng is actively driving research and development in several key areas to define the next generation of evaporation technology:
While Mechanical Vapor Recompression (MVR) offers the lowest operating costs by using electrical energy to compress and reuse vapor, high boiling point elevations can limit its application. Our future roadmap focuses on hybrid systems where MVR acts as the pre-concentrator, and a multi-effect forced circulation system handles the final crystallization stage, achieving optimal energy balance.
Fouling remains the primary cause of efficiency loss in heat exchangers. We are pioneering the use of advanced surface treatments, including hydrophobic coatings and electro-polished Duplex Stainless Steel (SAF 2205/2507) and Titanium tubes. These materials reduce crystal adhesion, extending operational cycles between Clean-in-Place (CIP) procedures by up to 40%.
By integrating IoT sensors into our forced circulation pumps and heat exchangers, we monitor real-time parameters such as flow velocity, pressure drop, and heat transfer coefficient. Machine learning algorithms analyze this data to predict scaling rates and schedule maintenance before unplanned shutdowns occur.
We are expanding the capabilities of our Waste Heat Evaporators to utilize ultra-low-temperature waste heat sources (such as dryer exhaust air and condenser cooling water) down to 55°C, turning previously wasted energy into a valuable thermal resource.
Our evaporation and drying systems are not standalone units; they are critical components of macro-level industrial processes. We design complete, turn-key process lines tailored to the specific regulatory and operational demands of key global sectors:
In chemical, petrochemical, and mining industries, environmental regulations mandate the elimination of liquid waste. Our multi-effect forced circulation evaporators act as crystallizers, separating dissolved salts from wastewater to produce clean condensate for reuse and solid salt cake for disposal or commercial sale.
In the fuel ethanol and starch industries, processing thin stillage is critical. Our evaporators concentrate thin stillage into syrup, which is then blended with wet grains and dried in our ZXG Tube Bundle Dryers to produce high-protein DDGS (Distillers Dried Grains with Solubles) feed.
Concentrating amino acids, organic acids, yeast extracts, and starch sugar solutions requires precise temperature control to prevent thermal degradation. Our falling film and forced circulation systems operate under deep vacuum, preserving product bioactivity and color.
