Abstract
Solar crop driers have been used in the Caribbean territories for the past twelve years. Crops dried have included sorrel, bananas, grass, nutmegs, ginger and screw pine. Several types of drier have been employed, varying from the simple wood-and-plastic wire basket drier to the metal-and-glass rock bed drier with chimney-assisted air circulation. Practical experience indicates that the most cost effective design is the wire basket drier with a plastic cover of UV stabilised polyethylene. For crops which require higher or more stable temperatures, the open cycle natural convection rock bed drier may be used. Rock-bed driers have been built in Barbados, Jamaica, Dominica, Grenada and Trinidad & Tobago, wire basket driers have been used in St. Lucia, Dominica, Guyana and Trinidad and Tobago. Simple cabinet driers have also been used, but they lack the simplicity of the wire basket drier and the heat storage capacity of the rock bed driers. ----- Durante los (iltimos doce anos, se ha utilizado secadores solares en el Caribe para secar cultivos tales como la acedera, los bananos, la hlerba, la nuez rnoscada, el jengibre y la pandanea, Se ha empleado variias clases de secadores, del sencillo secador de madera y plastico con red de alambre hasta el secador de vidrio y metal con lecho de piedras y circulaci6n de alre por chimenea, La experiencia practica indica que el diseno mas rentable es la red de alambre con una tapa de plastico hecha de polietileno estabilizado contra los rayos UV. Para los cultivos que necesitan temperaturas mas altas 0 estables, se puede utilizar el secador de lecho de piedras de cicIo abierto y convecci6n natural. Se ha construido secadores de lecho de piedras en Barbados, Jamaica, Dominica, Granada, y Trinidad y Tobago. Se ha utilizado tambien los secadores sencillos en forma de gabiente, pero estos son mils complejos que la red de alambre y no tienen la capacidad de almacenamiento calorifico de los secadores de lecho de piedras.
