Abstract

A solar-assisted fluidized bed drying was evaluated for 12 kg of paddy. It was dried to the final moisture content of 14 from 20% (wet basis) in 40 min with temperature and relative humidity about 50°C and 23%. Also, a maximum and average drying rate of 0.04 kg/min and 0,022 kg/min, respectively. Result shows that this system capable of drying paddy quickly because the drying rate is quite high. The drying system consists of single-pass solar collector with fin, fluidized bed, cyclones, blower and drying chamber.

Keywords:
