Secagem de milho utilizando energia térmica de um gasogênio de fluxo transversal descendente.

Abstract

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.
