Empowering Agricultural Efficiency: Low-Cost Filter Mesh for African Crop Dryers

In many parts of Africa, post-harvest losses exceed 30% due to inadequate drying and contamination during crop processing. As solar-powered and biomass-fueled agricultural dryers become more prevalent, the need for a reliable, low-cost, and sustainable filter mesh solution becomes critical. Our low-cost filter mesh meets this challenge head-on, blending affordability with durable performance across varied African climates.

Manufactured from UV-resistant HDPE, anti-rust galvanized steel, or recycled aluminum mesh, our filter meshes are designed to trap dust, insects, and debris while allowing consistent airflow through solar or mechanical dryers. The lightweight mesh is easy to cut, install, and clean—making it ideal for rural cooperatives, local farmers, and development aid programs focused on smallholder agricultural systems.

In Kenya’s Machakos County, our filters were used in 36 solar tunnel dryers through a local food security project. Farmers drying mango, maize, and cassava reported a 41% decrease in spoilage and a 25% increase in market-ready yield. This mesh replaced expensive stainless-steel grilles that had been cost-prohibitive for most cooperatives.

The filter meshes are field-tested under standards aligned with FAO Postharvest Guidelines, Global Agrifood Network frameworks, and regional climate durability tests conducted with AUDA-NEPAD. They withstand temperatures up to 90°C and wind pressures of 150 kPa—ensuring safety in high-heat biomass dryers used in Nigeria, Uganda, and Ethiopia.

Use cases include:

• Tomato and pepper solar dryers in Northern Ghana

• Groundnut shell dryers for oil extraction cooperatives in Senegal

• Herbal plant dryers in Rwanda’s organic farm collectives

A pilot in Mbale, Uganda showed that by switching from open-mesh jute cloth to our structured perforated mesh, mold incidents dropped by 38% during rainy season drying, and drying time reduced by 19%. Local women-led cooperatives also praised the filter’s ability to be washed and reused over 20 cycles without degradation.

Designed for Resource-Limited Environments

Our meshes are:

• 🌍 Lightweight and low-cost (under $1/m²)

• 🦟 Insect-barrier rated at 200–300 micron mesh

• 🔥 Heat-stable for both solar and firewood dryers

• 💧 Washable for multi-season use

• 🔧 Mountable with low-skill tools (zip ties, clips, adhesive sealant)

We support bulk procurement via NGOs and development banks and offer regional support from hubs in Nairobi, Accra, and Lagos. Our filter meshes integrate with local dryer models, including Hohenheim solar tunnel designs and CTA agro-processing units.
