Sun Drying: In sun drying method, samples were placed
on a suitable stainless steel mesh and exposed to direct
solar radiation at a suitable site in the open air. During
drying, samples were weighed at the beginning and after
regular interval of 2 hrs until the weight of the samples
become constant to calculate the rate of moisture loss
shown in Fig. 1b. The drying time was calculated taking
into consideration day and night hours.
