Monsoon Rice
Drying Solution

High-humidity monsoon climate pushes paddy moisture above 25%. GXON configures the G-SR-30 batch dryer with a rice husk furnace — turning mill waste into free drying fuel while cutting fuel costs by up to 60% and reducing post-harvest losses from 25% to under 5%.

THE CHALLENGE

When Monsoon Meets Harvest

South Asia's monsoon season aligns with the rice harvest — creating a perfect storm of high humidity, heavy rainfall, and grain that spoils within 48 hours.

Humidity That Defeats Sun Drying

During the monsoon months (June–September), ambient humidity across Bangladesh, eastern India, and Pakistan routinely exceeds 80%. Paddy harvested during this period carries 25–30% moisture content — far above the 13–14% safe storage threshold.

Traditional sun drying becomes impossible: there is no sun, and the ground is waterlogged. Grain left in these conditions begins to sprout, ferment, or develop mold and aflatoxin within 48 hours. Farmers lose 15–25% of their harvest every season.

Rice Husk: Waste or Resource?

Every rice mill in South Asia generates mountains of rice husk as a byproduct. Most mills dump or burn it inefficiently, creating pollution. But rice husk has a calorific value of 3,000–3,500 kcal/kg — making it an excellent fuel for grain drying. GXON's solution turns this waste into free fuel.

SOLUTION CONFIGURATION

Engineered for Monsoon Conditions

Three core components configured specifically for South Asian rice drying: batch dryer, husk furnace, and dual-use silo.

G-SR-30 Batch Grain Dryer
Dryer
G-SR-30 Batch Dryer
30-ton batch capacity with PLC automatic control. Cycles 2–3 batches per day for 60–80 TPD throughput. Designed for fixed installation at rice mills and grain stations.
Capacity30 T/batch
Throughput60-80 TPD
Power15 kW (3-phase)
Rice Husk Furnace Burner System
Fuel System
Rice Husk Furnace
Burns rice husk directly — converting mill waste into free drying fuel. Gasification combustion ensures clean, efficient burning with minimal smoke. Compatible with diesel/wood backup.
FuelRice Husk
Consumption15-20 kg/ton
BackupDiesel / Wood
Dual-Use Silo Dryer Storage
Storage
Dual-Use Silo
Dries grain and then seals for storage in the same unit. Eliminates the need for a separate storage silo — saving capital investment and reducing grain handling losses.
ModeDry + Store
Seal TypeAirtight
Storage Period3-6 months
HOW IT WORKS

The Drying Process

From wet paddy to storage-ready grain in five automated steps.

1
Load Paddy
Harvested paddy at 25–30% moisture loaded into the 30-ton batch chamber via elevator.
2
Husk Ignition
Rice husk furnace ignites. Heated air is channeled indirectly — flue gas never contacts grain.
3
Auto Drying
PLC controls temperature (50–60°C) and cycle time. Dual sensors monitor air and grain temperature.
4
Grain Agitation
Auto grain agitator circulates paddy for uniform moisture reduction — no manual turning needed.
5
Seal & Store
Once moisture reaches 13–14%, the dual-use silo seals for storage. No transfer needed.
BENEFITS & SAVINGS

What This Solution Delivers

Quantified impact for rice mills, cooperatives, and grain stations in South Asia.

-60%
Fuel Cost
Free Fuel from Mill Waste
Rice husk replaces diesel or gas. A mill processing 50 T/day generates enough husk to fuel the dryer at zero cost.
<5%
Post-Harvest Loss
From 25% Down to 5%
Mechanical drying eliminates mold, sprouting, and aflatoxin — saving 20% of harvest that would otherwise be lost.
1
Operator
Replaces 8-10 Workers
PLC automation and auto agitation mean one operator supervises the entire drying cycle — no manual grain turning.
2-in-1
Dryer + Silo
No Separate Storage Needed
Dual-use silo eliminates capital investment in a separate storage facility. Grain stays in the same unit for 3–6 months.
60-80
TPD Throughput
Keeps Pace with Harvest
2–3 batches per day handle the peak monsoon harvest volume without bottlenecks.

Per Batch
Fast Drying Cycle
PLC auto-adjusts drying time based on real-time moisture readings — no over-drying, no under-drying.

FAQ

Common Questions

How much rice husk do I need per ton of paddy?
Approximately 15–20 kg of rice husk per ton of paddy, depending on initial moisture content and ambient temperature. A typical rice mill processing 50 tons of paddy per day generates enough husk to fuel the dryer for the same volume — making fuel cost effectively zero.
Can the dual-use silo store wet grain before drying?
No. The silo should only be sealed for storage after grain has been dried to safe moisture level (≤14% for paddy). Storing wet grain will cause mold and aflatoxin growth within 48 hours. The drying cycle must complete before sealing.
What if my rice mill is too far from the drying site?
The G-SR-30 supports multi-fuel operation. If rice husk transport is not economical, the burner can be switched to diesel, natural gas, or biomass pellets. The husk furnace is a modular add-on that can be detached and reinstalled at a different location.
How long does one drying batch take?
4–6 hours per batch depending on initial moisture (25–30% down to 13–14%), ambient humidity, and grain type. The PLC auto-adjusts drying time based on real-time moisture sensor readings — ensuring consistent results regardless of weather conditions.
Is the system suitable for parboiled rice?
Yes. Parboiled paddy typically enters the dryer at 30–35% moisture after steaming. The G-SR-30's temperature control (50–60°C) is ideal for parboiled rice — preventing fissuring and head-rice breakage while achieving uniform drying to 13% moisture.
What warranty and after-sales support is available?
12 months from delivery date covering manufacturing defects in materials and workmanship. GXON provides remote technical support, spare parts shipping within 7 days, and on-site engineer dispatch for major issues. Extended warranty up to 24 months and annual maintenance contracts are available at additional cost.
