Optimized for dynamic starch, organic meals, and agro-residue drying under Lima's coastal atmospheric conditions.
Multi-stage hydrocyclone systems engineered for potato, cassava, and native tuber processing plants in Lima.
Heavy-duty indirect steam-heated drying solution engineered with high corrosion resistance for regional processing plants.
Multi-effect evaporators designed to maximize heat-sensitive juice, dairy, and starch slurry concentration with low thermal stress.
As the primary economic and industrial hub of Peru, Lima serves as the nerve center for agricultural processing, starch extraction, mineral concentration, and industrial wastewater treatment. In the industrial corridor spanning Callao, Huachipa, and Lurín, processing plants encounter unique challenge sets, namely coastal marine relative humidity (averaging 80%-95% year-round due to the Humboldt Current) and strict municipal regulations regarding wastewater discharges (VMA limits) and carbon footprint reductions.
Standard open-atmosphere or rotary direct-fired drying systems suffer massive efficiency losses when subjected to Lima's humid air intake. This is where Pneumatic Airflow Dryers (Flash Dryers), such as the Jiangsu Zongheng MQG Series, establish their operational dominance. By implementing closed-loop high-velocity thermal air currents, the MQG system suspends materials in milliseconds. This rapid vaporization allows manufacturers of corn starch, cassava starch, and native tuber flours to bypass regional atmospheric limits, ensuring final product moisture targets of <12% without risking thermal degradation of heat-sensitive starches.
Our airflow dryers operate via a high-performance impulse design. Wet cake or slurry is introduced into a high-temperature pneumatic duct via custom-designed screw feeders. Once inside, high-speed hot air (velocities exceeding 20-30 m/s) forces the material into a fully fluidized state. The tube diameter varies dynamically along the structural route. This design causes the particles to continuously accelerate and decelerate, breaking down boundary layers and drastically increasing the thermal heat transfer coefficient.
For operations located in Lima's industrial zones, this brings substantial thermodynamic benefits:

| Evaporative Capacity | 300 - 1000 kg/h | 1200 - 3500 kg/h | Compensated via pre-heaters |
| Retention Time | < 1.5 seconds | < 2.0 seconds | Controlled via tube geometry |
| Product Recovery Rate | > 99.5% | > 99.8% | Dynamic bag filter integration |

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. In modern starch, DDGS, and agro-processing plants, integrating these evaporation systems directly with flash drying exhaust air loops enables zero-liquid-discharge (ZLD) operations and captures heat energy that would otherwise escape into the atmosphere.

When delivering machinery from our manufacturing base in Yixing to the Port of Callao (Lima), we focus on ensuring equipment durability, smooth customs handling, and straightforward commissioning protocols.
Our global growth roadmap focuses on structural resilience and thermal optimization:
Lima's industrial areas face salty air that can accelerate rust. We construct all exterior casings, ductwork, and separation cyclones from high-grade AISI 304 or AISI 316L stainless steel, adding passive surface treatments to resist environmental corrosion.
All drying plants use modern Siemens PLC panels running custom PID control algorithms. These systems continuously adjust fuel feed rates, hot air temperatures, and feed speeds, maintaining stable product output even when ambient humidity changes throughout the day.
We provide bilingual (English/Spanish) design drafts, P&ID layout schematics, and structural calculations. For installation, we offer remote video support or send on-site engineers to assist with assembly, balancing, and training local technicians.
High ambient relative humidity, typical of Lima's coastal climate, reduces the air's natural moisture carrying capacity. To maintain high efficiency, we adjust the combustion heating profile or add pre-dehumidification systems to the air intake. This ensures the air enters the drying column with the correct thermodynamic potential to absorb moisture from the material.
The MQG Series is designed for free-flowing, moist granules and powders, including starch (corn, cassava, potato), gluten, wood meals, organic fibers, chemical salts, and processed mineral residues. Materials must be pre-conditioned using a screw press or centrifuge to ensure they feed smoothly without sticking or clumping.
Jiangsu Zongheng holds the ASME "U" Stamp and is ISO 9001:2015 and CE certified. All pressure vessels undergo strict non-destructive testing (NDT), hydrostatic tests, and structural inspections before leaving our factory, ensuring they meet the safety standards required by local regulatory bodies in Peru.
Fabrication timelines range from 60 to 90 days, depending on custom design specifications. Sea transit from Shanghai to the Port of Callao takes approximately 30 to 40 days. We pack all equipment securely in standard or open-top containers, protecting sensitive parts with rust inhibitors and shrink wrapping.
Hot exhaust air from the airflow dryer is routed to the first-effect heat exchanger of a waste heat evaporator. The latent heat in the exhaust vaporizes moisture in the incoming liquid feed. This thermal loop lowers overall steam consumption, helping plants reduce energy costs and improve utility efficiency.
We provide full installation drawings, connection layouts, and operational manuals in Spanish. Our technical team supports commissioning through remote video links or sends engineers to your facility in Lima to supervise assembly, perform system balancing, and train your local operators.
