Hervé Guéa is a researcher from Cameroon who has invented a gourd seeds husking machine for the species Cucumeropsis Mannii Naudin or Cucumeropsis Edulis. These seeds have different names: gousi, egoussi, egusi-itoo, dark egusi, lipupu, white seed melon.
Between 2005 and 2008, Hervé Guéa developed his prototype which helped him validate the principle of shelling by combination of movements submitted to the seed, and forces with variable intensities applied to its edges. He filed his project with OAPI (African Intellectual Property Organization) in 2009 and obtained patent No. 14477.
The egusi-itoo seeds are used to make several dishes, and the oil extracted from the seeds is suitable for cooking, soap making, etc.

Existing husking machines are used for seeds such as rice, sorghum, corn, wheat, soybeans, fonio, peanuts... The principles used in these machines (shelling by abrasion, friction or projection) cannot apply to egusi-itoo seeds because they have specific physical characteristics.
