The traceability of many products can be realized easily but there is needed optimization for cereals which are usually transported as a bulk good. One possibility is given by RFID-Tracern (radio frequency identification) so-called corn dummies. These corn dummies shall remain in the cereal batches from the combine until shortly before the processing in a mill. The design and the characteristics of the corn dummy are important for a save marking of the cereal batches. The corn dummy must correspond to the cereals approximately, so that no remixing takes place. The section agricultural engineering in Goettingen (Germany) has developed different corn dummies to test these on its suitability to mark different batches. The main differences are the form and the density. The experiment described here investigated the characteristics of the aforementined corn dummies in winter wheat under conveying conditions. The corn dummies were mixed with winter wheat. Each of these mixtures were transported vertically in an elevator and then horizontally in a chain trough conveyor. Finally, the mixtures were made to slip over a 45 degrees-angled tube and fall freely over a short distance on the floor. The three-dimensional distribution of the dummies in the grain heap was determined using a sample divisor. The result shows that the density has a greater influence of the remixing as the form. In addition, a density analogue to the density of the winter wheat is to prefer for the marking of the wheat batches.
