Abstract:
A cooling trial was carried out on 229 tonnes of soybeans at 14 per cent moisture content stored in a vertical concrete bin in Israel during the summer of 1971. During this period two cycles of heating were recorded and heating foci reaching temperatures of 47 and 41°C respectively, were cooled by aeration using a chilling unit of 42,500 kcal/hr capacity. The two cooling passes resulted in moistening of grain around the aeration duct, and a slight overall drying effect on the soybean bulk. Germination remained stable except around and above the heating foci. Energy consumption required for conservation of the soybeans from early February until late August was about 9 kW/hr/t, and the bulk was at each pass cooled to around 20°C at rates of 121 and 112 t/24 hr. © 1973.
