Designing a fonio mill; Screening an operating principle and its validation

Marouzé C., Thaunay P., Fliedel G., Cruz J.F.. 2008. AMA - Agricultural Mechanization in Asia, Africa and Latin America, 39 (3) : p. 9-15.

Fonio milling is a long and laborious operation that needs to be mechanized to promote production and marketing of this cereal. The article presents an approach for the design of a fonio mill from definition of the equipment specifications to presentation of the knowledge required to develop the equipment. After investigating several principles, the authors selected the principle of the Engelberg mill used for other cereals such as rice. The choice of operating principle was based on understanding the milling principle. The design relies on the hypothesis that reducing the volume of the milling chamber will result in greater friction and shearing of the grains between the rotor and the stator, allowing them to be milled without excessive heating.
