Rice is used as a staple food by more than 60 percent of world population. The method used for Cooking of rice for eating purpose is most common and popular. Rice starch is used in making ice cream, custard powder, puddings, gel, distillation of potable alcohol, etc. It is used in confectionery products like bread, snacks, cookies and biscuits. The defatted bran is also used as cattle feed, organic fertilizer (compost), and medicinal purpose and in wax making. Rice is used as animal feed, fuel, mushroom bed, for mulching in horticultural crops and in preparation of paper and compost. Rice yields have been increasing since the 1960s, but since the 1990s, growth in rice production has been slower than population growth. Indeed, it is anticipated that rice production will need to increase by 30% by 2025 in order to sustain those who need it for sustenance. In the present work fluidized bed drying method used for safe storage of rice and analysis of rice conditions and we find that inlet air temperature has the most important effect on the drying rate of material, increasing the inlet air temperature increases the drying rate of the material. Inlet material flow rate has the most important effect on thermal efficiency. Increasing the inlet material flow rate increases the efficiency but decreases the drying rate. At lower flow rate of material, efficiency is low.
