In this paper the experimental simulation of a
Louisiana state university (LSU) paddy dryer system
has been presented. The continuous flow mixing type
LSU grain dryer , consists of rectangular drying
chamber ( 4.10 m ×2.35 m × 5 m), air blower powered
by 40 hp squirrel cage induction motor, heat exchanger
with duct , adjustable grain discharging system with
hopper bottom, 32 ton installed capacity for paddy was
considered for experimentation. The drying time for
different size paddy in different ambient conditions
have been measured. From obtained data drying rates
are calculated. The graphs for drying time in minute
verses moisture contents in dry basis (db), for thick and
medium size paddy, drying rate (R) verses moisture
contents, for thick and medium size paddy are plotted.
