started at 8:00 am and continued till 6:00 pm.
To determine the moisture loss of drying samples during experiments,okra samples were taken out of the solar dryer and weighed at various time intervals, ranging from 30 min at the beginning of the drying to 1hr during the last stage of the process.
The moisture loss of samples was determined with the help of a digital electronic balance having an accuracy of0.01 g.
These were again spread in the dryer in the next morning and the drying process was continued until no further changes in their mass were observed.
Also, to compare the performance of the solar dryer with that of open sun drying, both samples were dried simultaneously under the same weather conditions
