| This study aimed to investigate the impact of two options of two stage drying technique: (a) Fluidized bed drying, tempering and followed by sun drying method and (b) Fluidized bed drying, tempering and followed by fixed bed drying method on quality of BRRI Dhan28 rice variety in terms of head rice yield (HRY). Moist paddy was dried in fluidized bed dryer (FBD) as first stage drying to reduce moisture from 25-27% to 18-19% using drying temperatures of 120, 130, and 150°C at bed thicknesses of 8, 10, and 12 cm. The samples were immediately tempered and dried in second stage drying by fixed bed dryer using 40±1°C temperature maintaining bed thickness as 30 cm for the further reduction of moisture to 13-14% (wb). Sun drying method was followed as second stage... |
