As seen in Figs., all curves have two stages. The drying rate rapidly increases and then slowly decreases as dry ing progresses. In general, it is observed that drying rate reduces with time or with the reduction of moisture content. As mentioned earlier, the product’s moisture content reduces over time. The drying process took place in the falling rate period. Similar trend was also observed by Jain and Pathare (2007) for open sun drying of prawn and chelwa fish.
