Abstract

The objective of this study is to obtain, by means of a new design of the pipe which transports the hot air from the solar collector to the drying chamber, a uniform temperature inside the drying chamber so that the product to be dried deposited in all trays is evenly dehydrated. Outdoor drying experiments of agricultural products were carried out to test the thermal performance of a natural convection solar dyer constructed. Almost all the products were dehydrated in a single day. Since the quality of dried product depends significantly on the temperature of the drying process passive thermography -was used to monitor the product temperature during the drying process. The thermal images reveal that under climatological normal conditions the temperature gradient is 1-3°C among the apple slices placed in trays; the existing moisture in the surface of the specimens is homogeneously released and the maximal temperature attained by the product is less than 40°C when the irradiance is 1000 W/m² and the average temperature of the hot air in the drying cabinet is 55°C.
