Explore Tech SpecificationSantiago de los Caballeros, as the economic heartland of the Cibao Valley in the Dominican Republic, stands at a pivotal intersection of agricultural processing power and modern industrial expansion. Recognized for its robust manufacturing hubs—such as the Víctor Espaillat Mera Industrial Free Zone Center—the region demands advanced thermal separation and liquid volume reduction solutions. Modern factory operations spanning rum distillation, tobacco leaf processing, citrus extraction, coffee solubles, and pharmaceutical manufacturing require high-efficiency industrial evaporators engineered to meet both aggressive economic targets and stringent local environmental regulations.
In recent years, industrial growth across the Cibao region has heightened the focus on resource stewardship, particularly concerning industrial water intake and wastewater discharge. Traditional single-effect atmospheric evaporation methods are no longer economically viable due to rising fuel import costs and grid electricity tariffs in the Caribbean. Consequently, industrial operators serving Santiago are transitioning toward energy-integrated multiple-effect evaporation (MEE) plants and high-COP Mechanical Vapor Recompression (MVR) technology. Jiangsu Zongheng Concentrating and Drying Equipment Co., Ltd. delivers world-class engineering experience directly tailored to these localized operational constraints.
Under the regulatory purview of the Dominican Republic’s Ministry of Environment and Natural Resources (Ministerio de Medio Ambiente y Recursos Naturales) and local municipal guidelines in Santiago, industrial effluent management has transitioned from simple compliance to an operational imperative. Wastewater discharge into the Yaque del Norte river basin is subject to strict biochemical oxygen demand (BOD), chemical oxygen demand (COD), and total dissolved solids (TDS) thresholds. Our custom-designed evaporation plants act as prime Zero Liquid Discharge (ZLD) drivers, enabling factories in Santiago to recover up to 95% of process condensate for re-use in boiler feed, cooling towers, and facility washdowns.
MVR evaporators reuse latent heat generated during evaporation by mechanically compressing secondary steam using centrifugal blowers or turbocompressors. Operating on electrical energy rather than live steam, MVR systems installed in Santiago facilities achieve dramatic energy efficiency, reducing operational cost per ton of water evaporated to industry-leading lows.
Ideal for thermal-sensitive food, beverage, and botanical processing plants across the Cibao region. Liquid feed forms a ultra-thin liquid film moving rapidly down vertical tube bundles under vacuum. Extremely low residence times (measured in seconds) prevent thermal degradation, Maillard reactions, or loss of delicate aromatic compounds in rum and fruit juices.
Specifically engineered for heavy fouling, highly viscous, or salt-precipitating streams. High-capacity axial flow pumps force fluid through tubular heat exchangers at high velocity. Flash evaporation occurs exclusively in the vapor separator vessel, effectively mitigating heat exchanger surface scaling and tube blockage.
| Technology Type | Specific Energy Input | Ideal Application in Santiago | Scaling/Fouling Resistance | Condensate Quality |
|---|---|---|---|---|
| MVR Evaporation | 15 – 25 kWh / ton water | General effluent volume reduction, starch, distillery slop | Medium (with dynamic CIP integration) | High (TDS < 20 ppm) |
| Falling Film (MEE) | 0.18 – 0.25 kg steam / kg water | Citrus juice, sugar cane syrups, pharmaceutical intermediates | Low-Medium (Requires clear liquid feeds) | Very High (Boiler feed quality) |
| Forced Circulation | 0.22 – 0.32 kg steam / kg water | High-salinity ZLD crystallizers, chemical brine, complex waste | Extremely High (Turbulent anti-fouling fluid flow) | High (Process wash grade) |
| Waste Heat Evaporators | Direct waste heat utilization | Dryer exhaust vapor recovery, boiler flue gas integration | Medium | Medium to High |

Multi-stage hydrocyclone units specifically engineered for corn, cassava, and starch liquid concentration, fiber washing, and protein separation.
View Equipment DetailsThe Dominican Republic is internationally famous for premium rum production, with major operations based in and surrounding the Santiago corridor. Vinasse (mosto de destilería)—the liquid byproduct of sugarcane molasses fermentation—presents extremely high BOD/COD loads and intense coloration.
The Zongheng Solution: Implementing a multi-stage Falling Film Evaporator integrated with a Forced Circulation Finishing Stage. Raw vinasse (7-9% Brix) is concentrated to over 55-60% Brix syrup. The resultant concentrate can be directly combusted in specialized biomass boilers or processed into bio-fertilizer pellets, while pure evaporated condensate is recycled into washdown operations.
Agricultural processors in the fertile Cibao valley handle high volumes of passion fruit, mango, citrus, and guava. Maintaining fruit flavor profiles, natural color pigments, and vitamin content requires ultra-gentle thermal treatment.
The Zongheng Solution: Low-temperature, high-vacuum Falling Film Evaporation equipped with thermal vapor recompression (TVR) or MVR. Operating at boiling temperatures as low as 45°C to 55°C, our sanitary-grade Stainless Steel 316L systems preserve essential volatile esters while achieving target concentrate Brix levels efficiently.
Founded in 1992 (originally Yixing Yangxi Light Industry Machinery Factory), Jiangsu Zongheng has evolved into a global leader in concentration, evaporation, industrial drying, and Class III pressure vessel manufacturing. Spanning over 54,000 square meters with modern heavy manufacturing workshops exceeding 22,000 square meters, our facility holds ASME "U" stamp credentials, CE certification, and ISO9001 quality system accreditation.
As a core member of the China Starch and Alcohol Association, Zongheng maintains an elite engineering staff—including 3 senior staff engineers and over 20 specialized chemical, thermal, and mechanical engineering specialists. Our evaporators and dryers operate seamlessly across North America, Latin America, Europe, and Asia.
