Project Summary

On August 18, 2026, Guoxin Group completed the commissioning and operational handover of an industrial continuous mesh-belt corn drying project in Jining, Shandong Province. Designed to process high volumes of freshly harvested ear corn and grain during peak harvest seasons, the facility combines automated material receiving, mechanical husking, multi-tier mesh-belt thermal drying, and grain silo integration into a single continuous line.

A. High-Volume Raw Material Intake

• Heavy haul trucks unload fresh-harvested ear corn directly into raw material yards.

• Industrial front loaders feed bulk ear corn into heavy-duty receiving hoppers equipped with automated discharge feeders.

B. Mechanical Husking & Pre-Treatment

• Inclined chevron rubber conveyors transfer ear corn into integrated husking and cleaning units to strip husks and separate trash prior to drying.

• Cleaner material inputs maximize thermal transfer efficiency inside the drying chamber and prevent airflow blockages.

C. Zoned Multi-Layer Mesh-Belt Drying

• Corn ears/kernels are evenly distributed across multi-tiered SUS304 / galvanized mesh belts.

• High-volume convective blowers pass forced hot air uniformly through the bed. The gentle drop between conveyor tiers turns the material naturally, ensuring 360° drying without localized overheating or kernel cracking.

D. Centralized Automation & Safety Control

• Guoxin Group engineers configured an explosion-proof (Ex) control enclosure housing a digital PLC touchscreen.

• Operators monitor real-time multi-zone temperatures, air velocity, and belt variable-frequency drive (VFD) speeds to adjust retention time based on incoming moisture levels.

3. Key Engineering Advantages of the Jining Line

• Reduced Kernel Damage: Unlike traditional vertical grain tower dryers that rely on gravity drops—which can fracture high-moisture corn kernels—horizontal mesh-belt conveyance protects grain structure and preserves seed/grain quality.
• Integrated By-Product Handling: Corn cobs and husks are automatically separated and redirected via dedicated conveyors for biomass fuel or industrial byproduct utilization.
• All-Weather Continuous Operation: Heavy-duty insulated paneling maintains thermal efficiency under outdoor agricultural site conditions, drastically cutting fuel consumption per ton of dried grain.

FAQ

Q1: Why choose a continuous mesh-belt dryer over a vertical grain drying tower for ear corn processing?

A: Vertical grain towers require loose kernels that flow freely. High-moisture ear corn freshly harvested from the field cannot flow smoothly in a tower without prior shelling, which risks damaging soft, wet kernels. Continuous mesh-belt dryers handle whole ear corn directly, allowing pre-drying before or during shelling without clogging risks.

Q2: What heat sources can be integrated into Guoxin Group mesh-belt corn drying systems?

A: Our systems accommodate Natural Gas Burners, Steam Heat Exchangers, Biomass/Corn Cob Furnaces, or Air-Source Heat Pumps. Indirect heat exchangers are utilized when drying food-grade corn to guarantee that zero combustion exhaust contacts the grain.

Q3: How does the automated PLC panel manage fluctuating moisture levels in fresh corn?

A: Multi-point temperature and humidity sensors track moisture reduction at each conveyor tier. The Siemens PLC adjusts the belt drive speed dynamically—increasing retention time for wetter batches or accelerating throughput when processing lower-moisture harvests.
