Post-harvest losses reduced

Problem

Inaccurate Moisture Assessment: Grain traders, processors, and warehouse operators often face difficulties in assessing grain moisture accurately, leading to quality loss and spoilage.
Inaccurate traditional methods: Farmers rely on methods like biting or tossing grains, which are inconsistent and unreliable.
Limited access to affordable moisture measurement tools: Many farmers in sub-Saharan Africa cannot afford or find reliable grain moisture meters.
High risk of mold growth: Without proper moisture control, grains exceeding 13.5% moisture easily develop mold.
Negative impact on poultry farming: Feeding birds with high-moisture grains reduces egg production and increases disease and mortality rates.

Solution

Eliminates Guesswork: The moisture meter replaces unreliable traditional methods like biting or tossing grains, allowing farmers to make informed storage decisions.
Improves Accessibility: As an affordable –60 USD– and easy-to-use tool, it is accessible to a wide range of farmers.
Reduces Grain Losses: Farmers can use the device to measure accurately moisture levels and dry grains properly, preventing post-harvest losses and ensuring national food security.
Enhances National Planning and Advisory: Reliable moisture data collected from farmers can help governments and agricultural agencies monitor grain quality, predict storage risks, and design better food security policies.

GrainMate Components: GrainMate is composed of a handheld reader and a probe. The probe, housing the sensor, connects to the reader through a USB cable.
Moisture Measurement Process: To obtain a moisture measurement, the user inserts the probe into a sample of grain, selects the grain type, and presses the TEST button on the reader.
Type Selection on Reader: Users need to choose the grain type on the reader and then press the TEST button.
Data Processing: The device processes the collected data to determine the moisture content of the tested grain.
Background Test: The moisture test runs in the background, and after 2-3 minutes, the moisture content is displayed on the LCD screen.
