Off-Grid Batch Drying
for Cooperatives

A farmer cooperative in Kenya deployed a GXON G-SR Series fixed batch dryer with a multi-fuel burner and dual-use silo — bringing year-round drying and sealed storage to a region outside the electrical grid. Maize that once had to be sold at harvest can now be held for better prices.

CUSTOMER BACKGROUND & CHALLENGE

Drying Without the Grid

In off-grid regions, maize harvests arrive with moisture too high for storage — but without electricity, diesel-only drying is costly and supply-dependent.

A Cooperative Seeking Price Leverage

A farmer cooperative in Kenya aggregates maize from smallholder members across an off-grid region. Without drying infrastructure, members must sell immediately after harvest when prices are lowest — losing the leverage that storage would provide.

Maize arrives at moisture levels well above the 13% safe storage threshold and must be reduced before it can be held. The cooperative needs both drying and sealed storage to hold grain for months and sell when market prices improve.

No Grid, No Diesel Monopoly

The site has no grid connection, making electric-powered drying impossible. Diesel-only operation is costly and vulnerable to supply disruptions. The cooperative needs a multi-fuel system that can burn whatever is locally available — and a silo that doubles as storage.

SOLUTION CONFIGURATION

Engineered for Off-Grid Operation

Three core components configured for cooperative-scale off-grid maize drying: fixed batch dryer, multi-fuel burner, and dual-use silo with PLC control.

G-SR Series Fixed Batch Grain Dryer

Multi-Fuel Burner
Operates on diesel, biomass, wood, or coal. Ideal for off-grid sites where no single fuel is reliable — switch to whatever is available and affordable.

IMPLEMENTATION PROCESS

From Survey to First Batch

Four engineering stages to deploy cooperative-scale off-grid batch drying and storage.

1
Site Survey
Engineers evaluated off-grid power options, fuel supply chains, and silo placement on cooperative land.
2
Engineering
Batch dryer paired with quad-fuel burner and dual-use silo sized for cooperative member volume.
3
Installation
Fixed unit installed with sealed silo, commissioned and connected to backup generator for off-grid power.
4
Training
Cooperative staff trained on multi-fuel operation, moisture calibration, and silo sealing procedures.
OUTCOMES & BENEFITS

What This Deployment Delivered

Quantified impact for the cooperative and its smallholder members across the off-grid region.

% Loss Reduction
Maize Saved from Spoilage
Mechanical drying cuts post-harvest losses from mold and aflatoxin during storage — protecting member income.
Fuels Supported
Fuel Independence
Quad-fuel burner ensures operation regardless of which fuel is available or affordable in the off-grid region.
Months Storage
Hold Grain, Sell on Schedule
Dual-use silo lets the cooperative hold grain and sell when prices peak — not at harvest when prices are lowest.
The dryer paid for itself in — seasons. We dry, we seal, and we wait for the price we want — instead of selling everything at harvest.
