ABSTRACT:
An automated grain characterization system includes grain crushing apparatus; a means for singulating kernels of grain and feeding them into the crushing apparatus; a means for measuring kernel size; a circuit for measuring kernel conductance; and a data acquisition and analysis subsystem for correlating crushing force, size, and conductivity to grain hardness. The output is a profile of the grain characteristics which can be compared to reference samples. This system is especially useful for grading and classifying wheat and predicting its end-use functional properties.
