Résumé:
It was investgated the perfomance of a stacionary motor
with downword -flow gas gerator which moves a centrifugal fan
and receive thermal energy scatterad dor gaseificator gases,
beyond thermal energy scattered for gases of motor escape
though of heat gases-air, being this energy used for grain
drying in stationary layer. The experimental data were compered
with simulated data through Hukill and Thompson models, using
the 5ASG-3 programa to microcomputer developed by Storage
Tecnology Nucleus.
For three experimental tests of corn drying, with the gas
cooling, it was obtained average temperature of dryng air about
51°C, 54°C and 56°C and air flow about B.B7, 9.30 and 8.65
m3/min/m= of drier, respectively, being the heighs about 0.50
m, 0.30 m and 0.50m and initial moisture contents of 24.53"/.,
32.62/i and 40.44X in drier basis.
It was concluded that is possible to dry, on average, 0.35
ton of corn in about 11 horas, using temperatures of 51 to 56"C
fron thermal energy of a downword transversal flow gaseificator
and that tha Hukill and Thompson drying simulate models superestimated the experimental moisture cintent in funcion of the time.
