Affordable Mesh Solutions for Postharvest Drying in Sub-Saharan Agriculture

Across Sub-Saharan Africa, improving food preservation through accessible technologies is a top priority. From cassava to chili peppers, millions of smallholder farmers require cost-effective methods to reduce spoilage and increase the value of their harvest. Our low-cost filter mesh is purpose-built to meet this demand, delivering reliable filtration in solar and biomass dryers used across the continent.

Engineered from recyclable polymer blends and corrosion-resistant steel, the filter mesh maintains airflow while preventing insect intrusion, ash contamination, and mold development. At just 280–350 microns aperture, it balances filtration with optimal drying efficiency. The mesh is manufactured to tolerate rugged field use—resisting UV, water, wind, and even mild acids from fermentation or smoke exposure.

In Ibadan, Nigeria, the Agricultural Research Institute adopted our mesh in its rural dryer upgrade initiative. Replacing traditional cotton netting, our filters boosted post-drying hygiene ratings by 49% and cut postharvest mold contamination by nearly half during peak humidity season.

Our filter meshes are aligned with African Development Bank goals for agro-innovation and are now part of supply contracts with cooperatives supported by IFAD. Pilot usage in Tanzania’s Morogoro District showed enhanced shelf-life for sun-dried pineapple, where our mesh prevented direct UV degradation while ensuring airflow. Feedback noted better color retention and less weight loss in the final product.

Applications and Features

• Chili, millet, yam, and cassava dryers in West Africa

• Herb and spice processing units in Kenya and Malawi

• Fish and maize drying cooperatives in Mozambique

The design includes:

• 🌀 Fine mesh apertures for insect and dust filtration

• 🌞 UV-stabilized coatings for solar exposure

• 🔁 Washable and reusable structure (20+ cycles)

• 🛠️ Compatible with local dryer frames and NGO kits

• 🌱 Made from 30–50% recycled inputs

A women’s farming group in Kisumu, Kenya shared that switching to our mesh improved income by enabling consistent year-round drying for turmeric and ginger—products now exported to EU buyers. The mesh's resistance to cracking and easy installation (scissors + staples) made it ideal for remote villages with minimal toolkits.

We are collaborating with engineering students at Ashesi University to test modular mesh formats for mobile dryers in West Africa. These include antimicrobial-treated variants for animal feed dehydration. Support is also available via USAID Agrilinks for integration into farm-to-market programs.
