Résumé
A crop drier using solar energy to heat ambient air was designed for use in Northeast Brazil„ The drier uses no commercial forms of energy„ Air. is heated about 30°C by a solar panel, passes through a drying chamber, and out through a vertical chimney. Air flow is generated by buoyant forces resulting from the temperature differential. The solar drier will permit earlier harvesting of grain, thus reducing substantial field losses caused by birds, animals, and insects. It will also improve its storage capabilities. As a:result the drier, when fully developed, could help overcome the 20 per cent deficit in the grain supply predicted to occur in Northeast Brazil before the end of the 1980 decade„ Further studies should be conducted to increase air flow and improve distribution.

Mots clés : Grain — Drying. ; Solar energy. ; Agriculture — Brazil.
