Abstract:
Rice is the staple food for a large part of human population, in particular for the hundreds of millions of Asians, Africans, and Latin Americans living in the tropics and subtropics. About 65% population of India consumes rice. Drying is the one of the most important post-harvest processes to improve yield in rice production. Farmers mostly perform drying of rice traditionally by sun drying. Sun drying has many disadvantages such as: over-drying, animals feeding on the grains, spillage and nonuniform drying. The (SBD) is the latest low-cost drying technology developed by IRRI, Hohenheim University and GrainPro. It basically constitutes a drying chamber which is made up of a black polythene sheet at the bottom and UV stabilized PE sheet as the glazing material. A zipper is used to seam the glazing materials from both sides after spread of the materials. The ventilators are set up with the help of a collapsible aluminum bar frame. The SBD should be exposed to the sun throughout the day, so it needs to be set-up clear of buildings, trees or other structures that might provide shade at some time during the day. Several types of materials can be used for the glazing of STD. The criteria for selection of glazing material would depend on the transmission of solar radiation, strength, resistance to weathering, surface condensation properties, availability and cost. Ultra-violet stabilized polythene sheet is thus considered the best glazing material among commonly available materials. Therefore, various researchers concluded that Solar Bubble Dryer can be one of the best options for drying of rough rice.
