Engineered for extreme thermal transfer efficiency, corrosion mitigation, and precise reaction containment.
An authoritative guide on optimizing mass transfer, thermal control, and mechanical stability in heavy-duty process vessels.
Engineering Executive Summary: In modern industrial chemical synthesis, bio-fermentation, and food concentration, selecting the optimal vessel design—whether batch reactors, Mechanical Vapor Recompression (MVR) evaporators, or forced circulation units—determines long-term Operational Expenditure (OPEX) and yield consistency. Jiangsu Zongheng Concentrating and Drying Equipment Co., Ltd. integrates decades of metallurgical precision and thermodynamic modeling to fabricate ASME-compliant process units engineered for severe duty cycles.
Industrial batch reactors and industrial evaporators represent the core unit operations in chemical transformation and liquid-solid separation. The structural integrity of batch reactor vessels requires precise calculations regarding internal pressure dynamics, agitation torque resistance, vacuum collapse resistance under extreme operating temperatures, and stress corrosion cracking (SCC) mitigation.
At Jiangsu Zongheng, our engineering team leverages finite element analysis (FEA) to design pressure vessels certified under Category III medium and low-pressure standards, alongside international ASME "U" stamp compliance. Our reaction vessels feature high-efficiency heat transfer jackets (limpet coils, dimple jackets, or double-wall jackets) designed to maximize overall heat transfer coefficients (U-values) while keeping pressure drops to a minimum across heating or cooling thermal fluid circuits.
Unlike continuous flow operations, batch reactors operate under non-steady-state kinetic conditions. Achieving stoichiometric efficiency requires advanced impeller geometries—ranging from pitched blade turbines for solids suspension to anchor and helical ribbon agitators for high-viscosity viscous fluids. By pairing customized agitation systems with automated internal baffle configurations, Zongheng batch reactor systems eliminate dead zones, ensuring uniform temperature distribution and preventing localized hot-spot degradation of heat-sensitive compounds.
The convergence of low-carbon energy mandates, digital twin telemetry, and advanced alloy metallurgy.
Direct integration of Mechanical Vapor Recompression (MVR) drives with batch thermal loops. By utilizing high-efficiency centrifugal vapor compressors, steam consumption is reduced by up to 90%, transforming high-CAPEX energy usage into streamlined electrical efficiency.
Implementing Distributed Control System (DCS) nodes coupled with inline NIR spectroscopy and real-time viscosity telemetry. This enables predictive endpoint determination for reactions, automatic anti-foaming dosing, and automated CIP (Clean-In-Place) sequence optimization.
Expanding standard SS304/SS316L fabrication to include 2205 Duplex Stainless Steel, Titanium Grade 2, and Hastelloy C276 claddings, ensuring total resistance against high-chloride, acidic, and abrasive slurry mediums.
Tailored concentration, drying, and reaction systems developed for global chemical and agricultural processing plants.
Integration of YDX Starch Washing Cyclones and Zongheng Degerming Mills to deliver max kernel separation efficiency, low fiber carryover, and high starch recovery yields across large-scale grain processing lines.
Leveraging continuous ZXG Tube Bundle Dryers and low-oxygen thermal evaporation systems to dry distillers dried grains with solubles (DDGS), reducing thermal degradation while reclaiming flash steam heat energy.
Pairing Forced Circulation Evaporators with high-salinity crystallizers for industrial wastewater treatment. Engineered to handle scaling-prone mineral salts without tube wall fouling.
Over 54,000 m² of modern production infrastructure situated in Yixing City, Jiangsu Province—the heart of China's chemical machinery manufacturing cluster.
Jiangsu Zongheng operates as a direct OEM and custom engineering factory, bypassing third-party supply chain markups to offer global EPC contractors direct factory-gate pricing. Our integrated production plant encompasses heavy rolling machines, automated submerged arc welding (SAW), high-precision CNC tube-sheet drilling, non-destructive testing (NDT) rooms, and dedicated hydro-testing bays.
With over 22,000 m² of dedicated production workshops, we handle vessel fabrications weighing up to 100 metric tons per unit, guaranteeing fast turnaround lead times for rapid project deployment.
100% radiographic weld testing (RT), ultrasonic testing (UT), dye penetrant inspection (PT), and helium mass spectrometer leak detection to ensure zero defect tolerance on heavy pressure equipment.

Mechanical Vapor Recompression (MVR) evaporators utilize energy generated by re-compressing secondary vapor back into thermal energy. This dramatically reduces live steam input requirements. Highly applicable for chemical wastewater concentrate, amino acid concentration, and continuous industrial evaporation processes.
Designed for heat-sensitive liquid matrices such as milk, juice, biological extracts, and delicate pharmaceuticals. Liquid forms a uniform thin film descending down vertical heating tubes under vacuum. Short residence time prevents thermal degradation and maintains fluid purity.
Built for liquids prone to scaling, high viscosity, or crystallization under concentration. External circulation pumps drive high liquid velocity inside heat exchanger tubes, suppressing boiling inside the tube package to eliminate scaling and tube fouling.
Indirect steam-heated industrial drying machinery operating under low oxygen conditions. Features a rotating internal tube bundle providing high heat contact surface area per unit volume. Ideal for germ, fiber, starch, and gluten drying applications.
Employs ultra-high-speed hot air stream to suspend and fluidize moist materials during pneumatic conveyance. Impulse airflow tubes tumble material continually, delivering rapid surface drying within seconds.
High-efficiency cyclone batteries engineered for starch refining, cell washing, and impurity removal paired with high-torque degerming mills for precise corn germ liberation without starch kernel fracture.
Meeting the international engineering standard for multinational plant deployments.
