Engineered to Save Labor, Built for Automation
Every component is designed to reduce manual work and deliver consistent drying quality — from the burner to the control system.
Multi-Fuel Burner System
Auto-switches between 6 fuel types in under 30 minutes. The burner auto-calibrates combustion parameters for each fuel — no manual reconfiguration, no specialist required.
Diesel
Natural Gas
Biomass
Rice Husk
Wood
Coal- One-touch fuel switching via PLC touchscreen
- Auto air-fuel ratio calibration per fuel type
- Flame failure protection & auto-restart
PLC Control Cabinet
Automates the entire drying cycle — from temperature control to moisture sensing. One operator can supervise multiple machines remotely.
- Touchscreen HMI with intuitive interface
- Automatic moisture sensing & drying cycle control
- Remote alarm via SMS for temperature deviations
- Drying data logging for quality traceability
Dual Temperature Sensors
Monitors both hot air temperature and grain bed temperature in real-time. The PLC adjusts burner output automatically to prevent overheating or underdrying.
- Hot air sensor: ±1°C precision in drying plenum
- Grain sensor: monitors core grain temperature
- Auto shutdown if grain temp exceeds safety threshold
- Digital display on control cabinet
Auto Grain Agitator
Rotating auger inside the drying hopper prevents grain from sticking and ensures uniform moisture distribution. Eliminates the need for manual grain turning between batches.
- Auto-rotating paddle mechanism
- Prevents grain bridging and hot spots
- Ensures ±0.5% moisture uniformity
- Programmable rotation intervals via PLC
What Makes G-MR-20 Different
Engineering details that deliver value on every batch.
PTO + Electric Dual-Power
Tractor-driven PTO mode (90HP, 500 RPM) for off-grid sites, or electric AC380V mode (49.2 kW) when grid power is available — switch freely between the two.
900,000 KCAL/H Heat Output
Integrated diesel/kerosene burner delivers high heat output with a 530L fuel tank — sustained drying at 12–30 L/h fuel consumption.
6 Fuel Options
Diesel, LPG, natural gas, biomass pellets, wood, or coal — choose the most cost-effective local fuel for your operation.
Road-Speed Transport (15 Km/h)
Towed at up to 15 km/h with transport dimensions of 9.63 × 3.15 × 4.50 m — moves between sites without special low-boy trailers.
Where G-MR-20 Shines
Built for scenarios where mobility and flexibility matter most.
Small-to-Medium Farms
On-site drying without transporting wet grain to a distant facility. Reduces post-harvest losses and transport costs.
Agricultural Contractors
Move between multiple farm sites in a single season. Maximize equipment utilization across different client locations.
Emergency Harvest Drying
Rapid deployment after unexpected rain. Prevent grain spoilage in the field when weather threatens harvested crops.
Remote Area Operations
Diesel generator compatible. Operates where grid power is unavailable — ideal for off-grid farming regions.
Multi-Grain Processing
Switch between paddy, maize, wheat, sorghum, and soybeans with adjustable drying parameters per grain type.
Drying Service Business
Provide mobile drying services to surrounding farms as a revenue stream. Low barrier to entry, high demand in harvest season.
Key Performance Metrics
Quantified results from field operations across multiple grain types.
