Solar
radiation has been used for drying different
products for thousands of years. Solar energy
was the only energy used until the discovery of
fossil fuels sources. These dryers are not very
commercialized, and their designs are based on
empirical and semi-empirical systems. Therefore,
theoretical studies will be of high importance
in this field. In this article, a simulation of
a direct solar dryer system is developed based
on the heat transfers phenomena inside and
outside the dryer. This study is applied on five
different products to determine instant
temperatures of the product, of the internal air
of the dryer and of its cover, in addition to
the instant water content of the product dried.
Finally, a relation between the thermal capacity
of the product dried and a defined drying
characteristic time will be highlighted.
Key words: Solar drying, drying
characteristic time, thermal capacity.
