Method and apparatus for processing harvested root crops

摘要

The present invention relates to a method for treating harvested root crops such as potatoes. The method optically images (i.e., with a hyperspectral imaging system) a bulk stream of harvested root crops, generates image data, and analyzes the image data to analyze individual bulk streams. Identifying an object. Each identified object is screened as either acceptable 44 or unacceptable 40 based on a comparison with at least one discriminator, and objects classified as unacceptable (ejector actuator 38). To provide a selected stream of harvested root crops that has been removed from the bulk stream.
