Abstract
The drying characteristics of tapioca sago were studied using four different drying methods—Open sun drying (OSD), Conveyor belt drying (CBD), Bin drying (BD) and Fluidized bed drying (FBD)—in an industry located in Tamilnadu, India (Latitude: 11.494347° N; Longitude: 78.272264° E). The BD and FBD dryers were designed and fabricated as pilot scale models in the laboratory with respective capacity of 5 kg/h and 10 kg/h; CBD (1000 kg/h) and OSD are the commercial drying operations currently employed in industrial processing. The drying time, energy and exergy aspects of all the drying methods were compared along with the achieved final moisture content, color and quality of the dried products. The highest Energy utilization ratio (EUR) was found in CBD and FBD in the range of 20-76 % and 10-67 %, respectively. The exergy efficiency was initially low in all the cases but increased to 80 % towards the end of the drying process.
