The system for delivering tracing caplets into grain on a combine was developed as a part of a grain traceability system. A commercially available seed dispenser was utilized to meter tracing caplets into wheat in the combine bin tank during the unloading process. The caplets were delivered into the grain stream close to the unloading auger to attain uniform distribution. The distribution uniformity of caplets was sampled on five consecutive bin loads, with six 1-L grain samples from each load. The number of caplets in the samples was reasonably consistent at unloading time of 20 and 30 s when the grain unloading rate was stable. However, caplet concentration increased as grain flow was reduced at the beginning and end of each unloading event and caplets that remained in the grain tank sump after each test was discharged in high concentrations at the beginning of the subsequent unloading process.
