Colombia's geographic position and diverse microclimates provide a fertile foundation for large-scale cultivation of starch-yielding crops like cassava (yucca) and corn. In key processing hubs such as Valle del Cauca, Cauca, and the Caribbean coastal plains, local industries are transitioning from low-efficiency artisanal plants to high-throughput commercial complexes. Under this shifting economic reality, precision drying technology has become a critical operational threshold.
Traditional solar and low-velocity convective drying processes are no longer capable of meeting the stringent microbiological and moisture-uniformity requirements demanded by modern export standards. Commercial cassava starch processing requires rapid moisture removal to avoid retrogradation and enzymatic degradation. Pneumatic flash drying (airflow drying) addresses this specific challenge by conveying wet starch granules through a high-velocity stream of heated gas, removing moisture within milliseconds.
Jiangsu Zongheng’s advanced thermal systems assist Colombian producers in optimizing energy efficiency. Leveraging multi-stage heat recovery loops, our systems capture and recycle dryer exhaust, driving down fuel consumption in regions reliant on coal, natural gas, or biomass-fired boilers.
Our systems feature alternate variable-diameter impulse pipes. As wet material moves through narrow to wide sections, it accelerates and decelerates dynamically. This creates micro-turbulences that break up agglomerated materials, increasing the heat-transfer coefficient dramatically.
Standard drying towers often lose fine particulate to the atmosphere. We design multi-stage cyclone batteries integrated with optional dry bag houses. This configuration secures product recovery rates exceeding 99.8%, essential for high-value starches.
Cassava and corn slurries often contain corrosive organic acids (e.g., trace hydrocyanic acid). All contact parts are fabricated from polished SUS304 or SUS316L stainless steel, manufactured to ASME Section VIII pressure vessel protocols to resist corrosive wear.

Multi-stage evaporation systems designed to concentrate wash water in cassava starch processing, recovering soluble solids and minimizing environmental impact.
Installed prior to flash drying, these systems mechanically reduce moisture in fibrous organic waste, lowering energy demand in the thermal stage.
Excellent choice for long drying cycles of granular feeds such as corn germ, gluten meal, and DDGS, running continuously in Bio-fuel operations.
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.

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.

Installing industrial machinery in Colombia requires compliance with both international safety codes and local regulations. Our dryers, boilers, and evaporation systems are designed with these specific requirements in mind:
Cassava starch is highly heat-sensitive; exposure to high temperatures can lead to starch gelatinization. The MQG Airflow Dryer conveys the wet starch in a fluidized pneumatic stream, drying it within 0.5 to 2 seconds. The moisture evaporates rapidly, cooling the individual particles and keeping the starch temperature well below its gelatinization point.
Our airflow dryers optimize energy use. By using impulse pipes of varying diameters, we improve heat transfer efficiency. On average, the thermal efficiency ranges between 60% and 75%, depending on feed moisture, air temperature, and ambient conditions. We can also integrate waste heat recovery loops to capture exhaust heat and preheat incoming air, reducing fuel costs.
Yes. Jiangsu Zongheng has held the ASME "U" Stamp authorization since 2012. Our pressure components, heat exchangers, and steam bundle dryers are designed, fabricated, and inspected in compliance with ASME Section VIII Division 1 guidelines, meeting international safety requirements.
We supply high-efficiency cyclone collectors as the primary separation stage. For facilities operating under strict regional environmental regulations (such as CVC or CAR guidelines), we can add a secondary bag filter housing or wet scrubber. This combined setup keeps particulate emissions low, satisfying standard environmental requirements.
We provide full layout drawings, foundation blueprints, and piping plans. Once the equipment arrives at your facility in Colombia, we can send technical engineers to supervise assembly, run dry-cycle testing, calibrate control units, and train your operators on daily maintenance and safety protocols.
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 liquid streams, serving as a critical component in industrial thermal recovery and zero-liquid-discharge (ZLD) configurations.
