Learn MoreIndustrial evaporation forms the backbone of thermal separation processing globally. Selecting the right combination of Multiple-Effect Evaporation (MEE) or Mechanical Vapor Recompression (MVR) is a critical engineering decision that dictates long-term utility overhead and environmental compliance. Systems built by certified manufacturers ensure that complex heat integration loops align with pressure vessel directives (like the European PED 2014/68/EU or ASME Section VIII Division 1).
Jiangsu Zongheng Concentrating and Drying Equipment Co., Ltd. (formerly Yixing Yangxi Light Industry Machinery Factory, founded in 1992) has spent three decades refining energy transfer ratios. Our systems optimize the thermal energy of secondary steam. By implementing cascading pressure stages, the latent heat of vaporization is recovered multiple times, resulting in steam consumption ratios that can reach less than 0.2 kg of primary steam per kg of water evaporated in advanced configurations.
Whether handling food-grade corn steep liquor, starch derivatives, industrial wastewater crystallization, or complex chemical concentrates, our thermal design team matches fluid dynamics to heat transfer interfaces to eliminate boundary layer fouling.
How advanced material sourcing, industrial scale, and design automation combine to deliver competitive advantages.
By integrating strict European CE Mark (PED 2014/68/EU) guidelines, ASME "U" stamp protocols, and ISO9001 quality infrastructure, Jiangsu Zongheng ensures global compatibility. We source certified raw materials (duplex stainless steels like SAF2205, Titanium, and Hastelloy) to match the corrosive nature of complex process fluids.
Located in Zhoutie Town, Yixing City—a major Chinese industrial manufacturing cluster along Lake Tai—our facility enjoys direct access to precision component manufacturers, specialized sheet metal fabrication centers, and custom tube-extrusion plants. This geographical concentration lowers lead times and reduces structural costs.
Our localized design workflows integrate Mechanical Vapor Recompression (MVR) technology with multi-stage falling film designs. By using compressor packages to elevate secondary vapor temperature, the system recycles energy inside the loop, drastically dropping energy footprints.
In-depth inspection of specialized processing units engineered for durability under high operating stresses.
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'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, making it ideal for bulk processing lines.
Our machinery covers six core sectors, including:
Three decades of manufacturing evolution, certification milestones, and engineering growth.
Today, the company covers a total area of over 54,000 square meters, with production workshop space exceeding 22,000 square meters. It currently employs 3 senior engineers and over 20 engineers and assistant engineers, with a total staff of 120 people, delivering major turnkey concentration and drying plants worldwide.
Obtained international quality system certification (Certificate No.: 45021), establishing a complete quality assurance system aligned with international standards for engineering design and raw material traceability.
Acquired the ASME "U" Stamp authorization, marking the company's entry into a new phase of international development and certifying its capability to manufacture high-pressure vessels for the global market.
The company obtained the Special Equipment Manufacturing License of the People's Republic of China (License No.: TS2232C42), authorizing the production of Category III pressure vessels.
Jiangsu Zongheng Concentrating and Drying Equipment Co., Ltd, formerly known as Yixing Yangxi Light Industrial Machinery Factory, was established in 1992. The company initially covered a total area of approximately 15 mu and had a total of 45 employees.
How our engineering integrates into complex plant systems to ensure product quality and resource recovery.
In modern starch plants, hydrocyclones and MVR evaporators process corn steep liquor and distillers' grains (DDGS). Our high-efficiency evaporators recover solids from wastewater, generating sellable DDGS feed products and recycling pure hot condensate back into the wash plant, minimizing intake water demands.
Industrial plants produce waste streams loaded with heavy salts and organic elements. By using waste heat evaporators and multi-effect configurations, these streams are concentrated down to crystals or high-viscosity slurries, achieving Zero Liquid Discharge (ZLD) requirements.
Pharmaceutical ingredients degrade when exposed to heat over long periods. Our falling film evaporators maintain precise vacuum pressures, reducing boiling points below 50°C and allowing materials to transit through the heating zone in seconds.

Where the thermal separation industry is heading: from decarbonization to smart system automation.
As factories shift away from fossil-fueled boilers, the trend towards Mechanical Vapor Recompression (MVR) has accelerated. MVR systems run on electricity, using mechanical energy to compress vapor and raise its thermodynamic temperature. This eliminates the need for primary live steam during routine operations, providing carbon footprint reductions.
For materials like corn gluten feed, yeast, and grain residues, traditional open-air drying creates combustion risks and product degradation. Low-oxygen tube bundle dryers maintain an inert environment inside the process tube, preventing fire hazards and preserving the nutritional profile of organic proteins.
Modern concentration loops are integrating automated sensor arrays. By monitoring thermal heat transfer coefficient (HTC) degradation rates over time, AI diagnostic modules predict exactly when the scaling threshold will be reached. This enables plant managers to schedule clean-in-place (CIP) washes before scaling causes severe tube blockages.
