Abstract:
Two-hundred and forty-five tonnes of wheat in a concrete vertical bin were cooled by aeration with chilled air from a chilling unit (with a cooling capacity rated at 42,500 kcal/hr) to prevent development of insect populations. Initial temperatures of 21-21·5°C were lowered after 94 hr of cooling to 9·9-12·7°C. Under the ambient conditions the rate of cooling was limited by the aeration system of the bin. Cooled air entering the bin was at relative humidities higher than those in equilibrium with the grain moisture content and this caused moistening of grain around the aeration duct to above the critical level for safe storage under local conditions. A re-heater incorporated in the unit designed to reduce relative humidity of the cooler air was inefficient for the cooling of dry grain and reduced the cooling efficiency of the unit. © 1973.
