In industrial food processing, the concentration of liquids via evaporation is a critical step affecting product quality, nutrient density, flavor retention, and operating expenses. As a leading food evaporator manufacturer & supplier, Jiangsu Zongheng Concentrating and Drying Equipment Co., Ltd. designs advanced thermal separation systems. By applying strict thermodynamic principles, optimized heat transfer coefficients ($U$-values), and minimized residence times, we ensure that heat-sensitive biological products preserve their original quality.
Modern food evaporators must handle high viscosities, boiling point elevations, and potential scaling challenges while utilizing minimal utility power. Our systems integrate cutting-edge Mechanical Vapor Recompression (MVR) and multi-effect thermal technologies to minimize environmental footprints and operational costs.
We design custom equipment tailored to specific product properties, physical characteristics, and processing capacities. Our portfolio covers the entire range of thermal concentration technologies.
Specially engineered for highly heat-sensitive fluids. The process liquid enters the top distribution system, forming an extremely thin, uniform film flowing downward inside vertical heating tubes. With high heat transfer coefficients and low residence times, this system prevents thermal degradation, caramelization, and denaturation of food ingredients.
Ideal for crystallizing solutions, high viscosities, and fluids prone to fouling. The fluid is pumped through the heat exchanger at high velocities, preventing boiling on the tube surfaces. Evaporation occurs only when the liquid enters the flash separation vessel, minimizing scale and keeping cleaning cycles down.
An eco-friendly, energy-efficient choice. By recycling the latent heat from secondary steam through mechanical vapor compressors, this system reduces fresh steam usage by up to 90%. MVR plants lower operational costs and help food processing plants achieve carbon emission targets.
Designed to recapture low-grade energy from existing sources like dryer vapors and condensate. This technology is highly beneficial in starch refining, corn steep liquor treatment, and distilleries, turning waste thermal energy into a productive process asset.
Ensures safe, low-oxygen drying via indirect steam heating. By maintaining high heat transfer rates under precise control, these units are standard for drying fiber, germ, and gluten in the corn wet milling and bioethanol industries.
Utilizes high-speed hot air to suspend and fluidize materials. Impulse airflow, generated by varying the tube diameters, tumbles particles during transport to deliver fast, uniform drying for starch products.
Based in Yixing, Jiangsu—a prominent hub for industrial equipment manufacturing—Jiangsu Zongheng leverages a mature regional industrial supply chain. This ecosystem provides secure access to raw materials (such as SS304, SS316L, and Duplex Stainless Steel) and precision machining services, allowing us to maintain competitive delivery schedules and pricing without compromising quality.
Our manufacturing processes comply with strict international regulatory codes. We possess the ASME "U" Stamp Authorization, the Special Equipment Manufacturing License of the PRC, and ISO9001:2015 Quality Management System Certification. Every evaporator and pressure vessel is engineered, inspected, and documented to comply with CE, FDA, 3-A, and EHEDG guidelines, ensuring seamless integration into global food production facilities.
Our evaporators and processing machinery are deployed globally to optimize performance, recover resources, and support sustainable operations.
Our waste heat evaporators concentrate corn steep liquor (CSL), recovering key nutrients and reducing waste. Integrated systems with starch cyclones and bundle dryers process refined starch products efficiently.
We supply multi-effect and MVR evaporation units to process thin stillage into Distillers Dried Grains with Solubles (DDGS), maximizing byproduct value while returning clean water back to the plant.
By using forced circulation flash crystallizers and MVR technology, we support Zero Liquid Discharge (ZLD) operations, allowing companies to reclaim process water and meet strict environmental mandates.
