Abstract

A direct active solar dryer was designed and fabricated to dry Chester leaves (Heinsia Crinita ) within
one day but with features that will enhance its efficiency such as fans, battery, photovoltaic module,
storage unit. Thus, it achieved solar drying utilizing forced convection to enhance the drying operation.
Temperatures of the dryer were monitored on hourly basis while the moisture content analysis was done
on a two (2) hourly basis. Test results showed that under no – load conditions, the dryer achieved a
maximum temperature of 68.7
