Resumo: Grain drying using ambient was simulated under weather conditions in Botucatu. Hourly weather records, fry bulb temperature and relative humidity, from 1971 through 1975 and from 1977 through 1981, were used to calculate adiabatic drying potential of the ambient air. Historical weather records from 1971 were selected to simulate ambient air corn drying. Ambient air corn drying systems operating continuously are not feasible to reduce the moisture content of the grain to the moisture levels recommended for safe storage. Selective fan operation, from 9 a. m. to 5 a. m. , from 9 a. m. to 6 p. m. and from 8 a. m. to 6 p. m. , indicates the possibility to reduce corn moisture contents, wet basis, to levels between 12.1 and 17.3 percent for 22 percent initial moisture content, between 12.4 and 15.5 percent for 20 percent initial moisture content and between 13.1 and 14.7 percent for 18 percent initial moisture content, when corn is dried within allowable storage period. KEY-WORDS: Drying; Ambient air; Corn; Equilibrium moisture content.

Através do emprego de modelos matemáticos de simulação foi avaliada a possibilidade de realização da secagem do milho a granel com ar natural para as condições climáticas de Botucatu, com base nos registros horários de temperatura de bulbo seco e umidade relativa dos anos de 1971 a 1975 e de 1977 a 1981. O processo contínuo de secagem do milho com ar natural, nas condições analisadas, não permite a redução do teor de umidade final ao nível recomendado ao armazenamento seguro. A simulação da secagem intermitente, realizada nos períodos das 9 às 17 h, 9 às 18 h e 8 às 18 h, indica a possibilidade de redução do teor de umidade do milho, base úmida, a nível entre 12,1 e 17,3%, para o teor de unidade inicial de 22%, entre 12,4 e 15,5%, para o teor de umidade inicial de 20% e entre 13,1 e 14,7% para o de 18%, quando realizada a secagem no período máximo admissível.
