<br/><br/> According to Philippine Statistical Authority, Region I ranks fourth in paddy  rice production, accounting for 59.67 percent of the country’s total rice crops. Due to  the occasional unavailability of high grain quality and seasonal storms, the demand for  rice, a main source of energy, increases, driving prices up. Recent studies show that  fluidized bed dryers close this gap. This particular study focused on the design and  testing of a fabricated fluidized bed dryer for drying NSIC Rc160 rice grains. This  particular variety of rice has a sphericity of 0.363 and a density of 1071.73 kg m-3. The  minimum fluidization velocity is computed to be 1.4282 ms-1.Three bed heights were  tested namely 2, 4 and 6 cm. Through constant weighing process, the moisture content  is determined. The different bed heights of dryer were able to achieve a final moisture  content suitable for eight to twelve months of storage within twenty, thirty and forty  minutes of operation, respectively. The distribution of air significantly impacted the  uniformity of drying across different regions. The drying process displayed a two period drying rate, with an initial rapid drying phase followed by a slower drying rate.  Additionally, increasing the bed height was found to extend the drying time and power  consumption while reducing heat transfer due to a larger volume of contact.
