✦ Synopsis

A non-mechanical solar dryer based on convective heat and mass transfer and with energy storage has been constructed and tested to investigate the drying characteristics of various tropical products.

The dryer is constructed from materials available locally, and operates on solar energy. The solar collector is capable of transferring 118 W m-2 to the drying air at a temperature of 32~'C.

The moisture loss during the drying process can be described by a general equation of the form dM/dt = -kM. The drying constants kt and kz for the constant and falling rate periods are calculated.
