Tropical Multi-Grain
Drying Solution

Hot and humid tropical climate causes severe post-harvest losses across maize, sorghum, and soybean. The G-SR-32 batch dryer with dual-use silo dries grain and then seals for storage in one unit. Multi-fuel burner adapts to whatever fuel is locally available.

THE CHALLENGE

Tropical Humidity, Multiple Grains

West Africa's year-round high humidity attacks multiple grain types simultaneously — demanding a versatile drying solution that adapts to diverse crops and fuel supplies.

Year-Round Humidity, Year-Round Loss

In Nigeria, Ghana, Senegal, and Ivory Coast, ambient humidity stays above 85% for most of the year. Unlike monsoon regions with a dry season, West Africa's tropical climate offers no natural drying window. Maize, sorghum, soybean, and millet all require mechanical drying regardless of season.

One Dryer, Four Grains

West African farmers grow multiple grain types on the same land. A dryer that only handles one grain is underutilized. The G-SR-32 stores individual drying profiles for each grain type — switching between maize, sorghum, soybean, and millet via the PLC control panel in minutes.

HOW IT WORKS

The Multi-Grain Drying Process

From grain selection to sealed storage in five automated steps — built for tropical multi-grain operations.

1
Select Grain
Choose grain profile on PLC (maize/sorghum/soybean/millet). System auto-sets temperature and cycle parameters.
2
Load Grain
32-ton batch loaded via elevator. Mixed grains dried in separate batches — no cross-contamination.
3
Multi-Fuel Drying
Burner runs on cheapest available fuel. PLC maintains optimal drying temp per grain type (50–65°C).
4
Auto Agitation
Grain agitator circulates grain for uniform moisture. Critical for large 32-ton batches.
5
Seal & Store
Once at target moisture, silo seals airtight. Protects against tropical humidity re-absorption.

FAQ

Common Questions

How do I switch between grain types?
Select the grain profile on the PLC control panel. The system automatically adjusts drying temperature, airflow, and cycle time for the selected grain. Switching takes 2 minutes — no physical changes needed.
What fuel should I use?
It depends on local availability and price. In Nigeria, natural gas may be cheapest. In rural areas, agricultural waste (maize cobs, sorghum stalks) may be free. The multi-fuel burner handles all options — we recommend running cost comparisons for your location.
How long can grain stay in the silo?
Up to 6 months in airtight sealed mode. The silo prevents humidity re-absorption, which is critical in West Africa's tropical climate. Grain should be checked monthly for temperature and moisture.
Can it handle wet grain from the field?
Yes. Grain at 25–30% moisture can be loaded directly. The dryer handles 2–3 passes to bring moisture down to safe storage levels (12–14% depending on grain type).
What is the maintenance schedule?
Daily: clean dust filters. Weekly: lubricate elevator and agitation mechanism. Monthly: inspect burner nozzles and fuel lines. Annually: full system service by certified technician.
Is financing available?
