Design Specifications

The Pearl Millet Thresher is made up of a drum and screen thresher that strips, threshes, and winnows grain. The product is a hand-operated tool that is able to thresh 50 kg of millet per hour. It produces clean millet at a higher rate compared to the traditional threshing methods. The thresher can be moved around, enabling it to serve multiple farmers within a community easily.

Lifecycle

7-10 years

Manufacturer Specified Performance Parameters

The Pear Millet Thresher is designed to produce high-quality, clean grain at a rate 10 times faster than traditional methods and produce 50 kg of grain output per hour. Additionally, this product generates $42 USD per year as average savings vs other existing threshers, with a 2-year return of investment for farmers.

Vetted Performance Status

Through the Bountifield International's evaluations in Senegal, it was found that the stripper output is 43 kg/hr, the thresher is 60kg/hour, and the winnower is 44 kg/hr, with the optional grain grinder, which produces 20 kg/hour, all operated by hand. With traditional methods, a group of women can produce six kilograms of grain. With CTI's pearl millet tools, they can produce 45 to 60 kilograms.

Safety

The potential risk associated with the use of this product is that some grains might be caught in rotatory components.

Complementary Technical Systems

In the pilot product launch, Bountifield International proposed the selling of threshing services to neighbors, letting each entrepreneur select an appropriate service for their community. Upon returning to the communities, the company discovered that the fee-for-service model was effective among most of the communities.
