Non-Destructive Measurement of Moisture Pattern Using MRI in A Wheat Kernel during DryingPublished by the American Society of Agricultural and Biological Engineers, St. Joseph, Michigan www.asabe.org Citation: Paper number 053122, 2005 ASAE Annual Meeting . (doi: 10.13031/2013.19102) @2005Authors: Prabal K. Ghosh, Digvir S. Jayas, Marco L.H. Gruwel, Noel D.G. White Keywords: resonance imaging, wheat, drying, moisture distribution, decay rate Three-dimensional (3D) spin-echo magnetic resonance imaging (MRI) was used to study the moisture pattern in single wheat kernels during drying. Drying was performed at temperatures of 40 and 50oC using heated N2 gas with a velocity of 0.23 m/s. Individual wheat kernels of 20-64% wet mass basis moisture content were dried to study the moisture movement inside the kernel during drying. MR images were recorded at equal time intervals and moisture patterns were analyzed from the MR images of wheat kernels. Analysis of the images revealed that moisture loss from the seed parts differed significantly during drying. Influence of grain parts on the moisture distribution was also studied using mechanically scarified kernels and germ-cut kernels. (Download PDF) (Export to EndNotes)
