HarvestGuard: Small Cyclic Grain Dryer for Precision Drying
Product Introduction
Designed for smallholder farms, the HarvestGuard small cyclic grain dryer revolutionizes post-harvest processing with its recirculating technology. This compact yet powerful system addresses the core challenges of traditional drying—high breakage rates, uneven moisture distribution, and excessive energy consumption—by integrating a closed-loop drying cycle that reduces grain damage to below 0.1% while achieving 0.8% moisture reduction per hour .
Equipped with multi-layer angular box structures for optimal heat exchange, the dryer processes 15-30 tons of grain per batch, suitable for rice, corn, wheat, and oilseeds. Its modular design allows quick installation within 48 hours, making it an ideal solution for regions with limited infrastructure, such as Southeast Asia and sub-Saharan Africa .
Core Advantages & Selling Points
1. Revolutionary Cyclic Drying Technology
The cyclic process alternates between drying and tempering phases, ensuring uniform moisture removal without over-drying. Unlike traditional tower dryers, HarvestGuard recirculates hot air through staggered angular boxes, increasing heat transfer efficiency by 35% and reducing energy use by two-thirds . This results in:
- 0.1% Breakage Rate: Six-blade grain discharge mechanism minimizes mechanical damage, preserving grain quality for premium market prices .
- ±2% Moisture Uniformity: Smart sensors monitor humidity at multiple levels, adjusting airflow in real-time to prevent hotspots .
2. Multi-Fuel Efficiency for Global Adaptability
Designed to thrive in diverse energy landscapes, the dryer supports:
- Biomass Flexibility: Burns rice husks, straw, or wood chips—ideal for regions with abundant agricultural waste (e.g., Nigeria, Indonesia) .
- Hybrid Heating Options: Optional heat pump system reduces carbon emissions by 40% compared to diesel-fired dryers, appealing to EU green energy standards .
- 35-60kg/h Fuel Consumption: Equivalent to 1/3 the fuel use of conventional dryers, translating to $1,200 annual savings for a 20-hectare farm .
3. Intelligent PLC Control System
The touch-screen interface enables:
- One-Touch Operation: Pre-set programs for different crops (rice, corn, soybeans) eliminate operator error.
- Remote Monitoring: IoT connectivity allows real-time tracking of temperature (±1℃ accuracy) and moisture via mobile app, critical for multi-site operations .
- Auto-Stop Function: Automatically halts drying when target moisture (14-16%) is reached, preventing over-drying and energy waste .
4. Compact Design for Space Efficiency
With a footprint as small as 3.4m x 2.1m, the dryer fits into tight farm spaces while delivering industrial-grade performance:
- Modular Construction: Pre-fabricated components reduce installation time by 50% compared to concrete structures .
- Mobile Compatibility: Optional trailer mount allows easy relocation between fields or markets .
