Abstract:
This study determined effect of on the drying rate of tilapia in a solar tunnel dryer. Tilapia
fish was split into pieces of 4cm by 3cm by 9mm and soaked into four brine concentrations
varying between 0-15%. Moisture content was evaluated by oven drying method, while air
temperatures were with an automated data logger. The moisture content of fish reduced as
brine concentration increased. The effective diffusion coefficient varied between 5.061 *10-11
and 3.323*10-11 m2/s as brine concentration increased, and it decreased with increase in brine
concentration.
