Accuracy and Feasibility of Determining Single Peanut Kernel Moisture Content1

Abstract The accuracy of a single peanut kernel moisture meter (SKM) was determined on peanuts with moisture contents (mc) from 4 to 50%. Results indicated a significant difference between calibration curves determined over the 4–12% mc range and the 4–50% mc range. No mechanical failures of the SKM occurred; however, excess residue build-up on the SKM rollers affected the moisture meter accuracy. Correlation coefficients for average and single kernel moisture calibration equations were 0.88 and 0.91, respectively, for field cured peanuts over the range of 4 to 12% mc. Procedures for integrating the SKM into the present farmers stock grading process are discussed.
