Aware <strong>and</strong> Thorat - <strong>Solar</strong> <strong>Drying</strong> of Fruits <strong>and</strong> Vegetables<br />
agricultural products on a large scale would be a boon to small <strong>and</strong> marginal farmers.<br />
Among the different types of solar dryers, the indirect mode forced convection solar<br />
dryer has been demonstrate to be superior in the speed <strong>and</strong> quality of drying. Incorporation<br />
of sensible <strong>and</strong>/or latent heat storage media within the solar drying systems accelerate<br />
the drying process during the night time <strong>and</strong> low intensity solar radiation periods<br />
<strong>and</strong> exclude the need for using auxiliary heat sources during low solar radiation seasons.<br />
<strong>Solar</strong> drying of agricultural products appears to be financially quite attractive for cash<br />
crops (such as tea, cardamom, turmeric, ginger etc.) However, for drying highly perishable<br />
products such as fruits <strong>and</strong> vegetables, it is extremely important to develop low cost<br />
solar drying system preferably using local materials <strong>and</strong> skills. To improve the acceptability<br />
of solar dryers among the farmers, it is necessary to develop a large scale solar<br />
dryer, which is economically attractive.<br />
