Introduction: Revolutionizing Post-Harvest Efficiency in Jiangxi
Jiangxi Province, a pivotal “rice bowl” region in China, faces unique challenges during the harvest. The combination of dense harvest windows and frequent rainfall makes efficient post-harvest management critical. To address this, Presun was selected to implement a massive, multi-unit drying facility designed for industrial-scale efficiency.
This facility showcases the strategic deployment of multiple Presun 5HPX-30C Recirculating Grain Dryer Machines, a heavy-duty solution tailored to the demanding needs of large agricultural cooperatives.
Project Overview: Industrial Power Applied to Local Needs
The project’s goal was clear: to move away from weather-dependent sun drying and create a continuous, controlled environment for processing massive quantities of paddy rice.
The site plan features a centralized array of over ten 5HPX-30C units, each dedicated to a 30-ton batch. This multi-unit setup provides the operator with extraordinary flexibility, allowing them to dry different varieties of rice—or even different grains like corn—simultaneously without cross-contamination.
Location: Jiangxi, China
Primary Crop: Paddy Rice
Core Technology: Presun 5HPX-30C Recirculating Grain Dryer
Total Project Capacity: Multiple 30-ton units, providing hundreds of tons of daily capacity.
Key Components: High-volume centrifugal fans, multi-stage stainless steel drying sections, and PLC-based automated controls.
Spotlight on the Machine: Why the 5HPX-30C was the Right Choice
The 5HPX-30C (30-Ton Capacity) is the cornerstone of Presun’s industrial lineup. This model was chosen for the Jiangxi project because it addresses the specific pain points of processing paddy rice in a humid climate.
1. Precision Drying for Superior Rice Quality
For paddy rice, the drying process must be gentle to prevent “cracking” (fissures in the kernel), which dramatically reduces the market value. The 5HPX-30C uses a low-temperature, high-volume airflow method. The mixed-flow (cross-flow) drying technology ensures that every kernel receives uniform heat exposure, resulting in a significantly lower “broken rice” rate.
2. Robust 30-Ton Batch Capacity
A 30-ton batch is the perfect “industrial sweet spot.” It allows large volumes to be processed quickly (essential to beat the rain) while still allowing operators to isolate and manage specific grain batches from different fields.
3. Advanced Automation & PLC Control Panel
As shown in the project photographs, each unit is equipped with a modern PLC control interface. Operators can monitor temperature, humidity levels, and drying time in real-time. The system automatically adjusts parameters to maximize efficiency and can even provide automatic shutdown sequences once the target moisture content is reached.
4. Energy Efficiency & Multi-Fuel Compatibility
In Jiangxi, where fuel sources vary, the flexibility of the 5HPX-30C is a major advantage. These units are designed to integrate seamlessly with biomass burners, natural gas furnaces, or diesel heaters, allowing the operator to select the most cost-effective and environmentally friendly heat source.
Environmental and Economic Impact
The transition from old methods to the Presun 5HPX-30C system has had an immediate effect. The facility can now process entire harvests in days rather than weeks, effectively securing the farmers’ income against unpredictable weather. The energy-efficient design of the multi-stage burner system has also helped the cooperative reduce its operational carbon footprint by over 20%.
