Description: Post-harvest, grain is stored and commonly dried in on-farm bins. The careful control of drying and storage of the grain has significant effects on its quality. Recently, we have introduced a 3D imaging technology that creates an image of the permittivity and conductivity of the bin contents e.g., [Asefi, et al. Computers and Electronics in Agriculture, vol. 119, 2015] [Gilmore et. al. Computers and Electronics in Agriculture, vol. 136, 2017]. This imaging technology has applications for both monitoring and controlling of the drying process, as well as for long-term grain monitoring to ensure no losses occur during storage. In this presentation, we show the images of a grain drying experiment carried out on a small-scale storage bin (approximately 200 L of storage). Very wet wheat (>22% moisture content, wet basis) was dried with ambient air to safe storage levels (~14% moisture content) over 7 days. The contents of the bin were imaged every 4 hours using custom electromagnetic imaging equipment. The drying process was also monitored with in-situ humidity/temperature sensors. These results are the first ever images of in-situ grain drying and establish that the imaging technology is capable of monitoring and controlling industrial in-bin drying processes. The imaging results are in agreement with previous grain drying studies and will be discussed in detail.
