Abstract: A survey was carried out in Togo, Benin and Burkina Faso involving 140 respondents and three climatic zones. Ten typical types of dryers with batch operating and natural convection were inventoried. Analysis of the results showed that: (1) Traditional sun dryers were widely used everywhere from 1 to 4000kg per cycle, costing €0 to €7.63 per m2 drying area. (2) Low power solar dryers were mostly used in the Sahel and Sudan-Sahel tropical climate, from 5 to 1000kg, costing from €9.11 to €238.55 per m2 of tray. (3) Gas dryers were used in all climatic zones at around 100kg per cycle, with a high drying power, costing from €107.52 to €181.75 per m2 of tray. The acquisition of dryers depended mostly on the distance between provider and user and on the means of dissemination.
