EXECUTIVE SUMMARY
India has attained self-sufficiency in food production and three fourth of the population use rice as their staple food. The last kharif and rabi seasons accounted for 83.4 million tonnes of paddy production. Paddy is consumed either as raw milled rice or parboiled rice. In India more than 60% of the paddy is parboiled.
Drying paddy from moisture content of 30%-wet basis to 10% wet basis is an energy intensive operation. Due to the good sunshine available, open sun drying is widely practised for drying paddy. It is estimated that 1-5% of the produce is lost during the process of open sun drying. Conventional drying practices using machinery is slowly and steadily replacing open sun
