Industrial evaporation is a cornerstone thermodynamic process used for liquid separation, waste minimization, and chemical purification across global process industries. In an era marked by stringent decarbonization targets and rising utility costs, single-effect evaporation systems are rapidly being phased out. Industrial operations are shifting towards Multi-Stage Evaporator (Multi-Effect Evaporator - MEE) and Mechanical Vapor Recompression (MVR) designs to achieve optimum thermal efficiency.
By cascading stages where the vapor produced in one effect serves as the heating medium for the subsequent effect (operating at lower boiling temperatures), multi-stage systems reduce steam consumption exponentially. A single-effect system requires approximately 1.1 kg of steam to evaporate 1 kg of water, whereas a properly designed 5-stage system can drop steam consumption to under 0.22 kg per kg of water evaporated.
Globally, engineering procurement contractors (EPCs) and operators demand systems that not only conserve thermal energy but also offer long-term operational stability. This requires complex modeling of boiling point elevation (BPE), precise liquid distribution inside the tubes, and robust corrosion mitigation frameworks.
Reduces steam demands through advanced heat cascading, enabling significant operating cost (OPEX) reductions.
Allows factories to reach Zero Liquid Discharge (ZLD) thresholds, recovering clean water and isolating solids.
Located in Yixing, Jiangsu—the premier industrial machinery hub of China—Jiangsu Zongheng Concentrating and Drying Equipment Co., Ltd benefits from an established raw material supply chain and specialized metallurgy talent pool. Since our founding in 1992, we have optimized our 54,000-square-meter facility to deliver ASME U-stamp and CE-certified industrial equipment.

Engineered for heat-sensitive liquids, our systems allow feed to form a highly uniform thin film cascading down vertical heated tubes. This layout ensures minimal residence times, prevents product degradation, and offers high heat transfer coefficients under vacuum.
Built to handle highly saline, high-viscosity, and scale-prone liquids. Powerful recirculation pumps push the media through heat exchangers at high velocity, preventing premature boiling inside the tubes and suppressing scale formation.
Utilizing Mechanical Vapor Recompression technology, these systems recompress secondary steam to elevate its thermal state, routing it back as the primary heating medium. This cuts fresh steam consumption close to zero, providing unmatched ROI.

The evaporator absorbs heat to vaporize media, while the condenser releases heat to liquefy vapor; the two perform opposite cooling and heating functions. Operating under low pressure, the evaporator generates cold energy and concentrates target solutions efficiently...
