Efficient rice threshing and polishing for premium quality grains, boosting income and market access in african communities.
This technology uses special machines to help process rice after it's harvested. The first machine separates the rice from its protective covering. The second machine makes the rice look and taste better by gently polishing it. These machines are easy to move and can be used right in the fields where the rice is grown. They can be powered by generators or solar panels, so they work even in places with no electricity. Made from strong stainless steel, these machines are durable and easy to keep clean. This technology is a big step forward for rice processing, especially for farmers in Sub-Saharan Africa.
This technology is TAAT1 validated.

The adoption of Axial Flow Threshers and Improved Quality Polishing technology offers a promising solution to enhance agricultural efficiency and reduce labor-intensive tasks in rice production. Aligned with Sustainable Development Goals 2, 5, and 13, this technology facilitates increased productivity, potential relief from labor burdens, and promotes sustainable land management practices.
To integrate this technology into your project, consider the following steps and requirements:
Evaluate the size and number of equipment needed for your project, considering the cost of Axial Flow Threshers and Improved Quality Polishing technology. The prices of small bench-top polishers from commercial retailers start at 3,000 USD, while larger advanced polishers and whiteners are costing 15,000-20,000 USD. The processing capacity of polishers goes from 50-100 kg per hour for smaller bench-top systems, to 300-500 kg per hour for larger trailer-sized systems
Factor in expenses such as transportation costs, import duties, and taxes to accurately assess the total investment.
Engage a team of trainers to provide comprehensive training and post-training support for technology usage and maintenance.
Develop communication materials, such as flyers, videos, and radio broadcasts, to raise awareness about the technology.
Collaborate with agricultural development institutes and fleet managers to effectively implement the technology in your country.
