30/11/1999· When there’s nothing between the rollers, there’s no electrical conductance, but when wheat kernels are crushed between the rollers, a small amount of electricity is conducted to the second roller. When a wheat kernel that contains a live, juicy larva is crushed, the bug juice is a better conductor for the electricity, giving a spike in conductance. These spikes are monitored and counted by a computer, which can distinguish between wet kernels and insectsTable 5 from DETECTION OF WHEAT KERNELS WITH,DETECTION OF WHEAT KERNELS WITH HIDDEN INSECT INFESTATIONS WITH AN ELECTRICALLY CONDUCTIVE ROLLER MILL @article{Pearson2007DETECTIONOW, title={DETECTION OF WHEAT KERNELS WITH HIDDEN INSECT INFESTATIONS WITH AN ELECTRICALLY CONDUCTIVE ROLLER MILL}, author={T.

Approximately 70â 90% of the insect-infested kernels, being weaker, released internal insect pieces upon impact. The broken kernels were sieved with number 10 and number 20 sieves to obtain large-sieved and small-sieved fractions, respectively. Insect pieces in sieved fractions were counted. The insect piece counts were,Section 6 - Inspection and detection methods for,(vi) Ninhydrin system for insect detection.
