Resumo: Grain aeration using ambient air was simulated under weather conditions in Botucatu. Grain aeration potential was evaluated based on criterion of operating ventilation system if dry bulb temperatures are equal or lower than dew point temperatures of grain voids air. Hours in the favourable periods for safe aeration were computed, from 1971 through 1975 and 1977 through 1981, for allowed maximum dry bulb temperatures of 25°C, 23°C, 21°C, 19°C, 17°C, 15°C and 13°C. If maximum dry bulb temperatures are higher than 19°C, the selective aeration can be realized all the year. For maximum dry bulb temperatures between 13 and 19°C, selective aeration is suitable in April, May, June, July, August and September, being the best selective aeration conditions in June and July. Rewetting risks arise in the following order: rice, soybean, corn, wheat, bean and sorghum.

A aeração de grãos com ar natural é um processo dependente das condições climáticas locais, constantemente oscilantes no tempo. Através do emprego de modelos matemáticos de simulação foi avaliada a possibilidade de realização de aeração com ar natural para as condições climáticas de Botucatu. A avaliação do potencial de aeração foi baseada no critério de operação do sistema de ventilação somente se a temperatura de bulbo seco do ar ambiente fosse igual ou inferior à temperatura do ponto de orvalho do ar intergranular. Foram computadas as horas correspondentes aos períodos diários favoráveis, durante os anos de 1971 a 1975 e de 1977 a 1981, para as temperaturas de bulbo seco máximas admissíveis de 25°C, 23°C, 21°C, 19°C, 17°C, 15°C e 13°C. A aeração intermitente, baseada no critério da diferença de temperatura entre o ar ambiente e o grão, pode ser realizada, nas condições analisadas, durante o ano todo para as temperaturas máximas admissíveis superiores a 19°C. Para as temperaturas de bulbo seco máximas admissíveis entre 13 e l9°C, pode ser realizada nos meses de abril, maio, junho, julho, agosto e setembro, encontrando as condições mais favoráveis nos meses de junho a julho. A susceptibilidade ao reumedecimento cresce, por produto, na seguinte ordem: arroz, soja, milho, trigo, feijão e sorgo.Escola de Agronomia - Universidade Federal de Goiás2007-11-23info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionAvaliado por paresapplication/pdfhttps://revistas.ufg.br/pat/article/view/2463Pesquisa Agropecuária Tropical [Agricultural Research in the Tropics]; v. 14-16, n. 1, Jan./Dec. 1984-1986; 103-125Pesquisa Agropecuária Tropical (Agricultural Research in the Tropics); v. 14-16, n. 1, jan./dez. 1984-1986; 103-125Pesquisa Agropecuária Tropical; v. 14-16, n. 1, jan./dez. 1984-1986; 103-1251983-4063reponame:Pesquisa Agropecuária Tropical (Online)instname:Universidade Federal de Goiás (UFG)instacron:UFGporhttps://revistas.ufg.br/pat/article/view/2463/2421Gonçalves, V.
