contamination-free automatic grain sorter and methods for grading, testing and piling up beans

摘要

In the various embodiments, the present disclosure provides an automatic grain grading system including a grinding station for removing at least a portion of the grain coating material from a grain and a sampling station for extracting a sample of the grain material. from the grain, where the grain coating has been removed. A grain transport subsystem transports the grain between the grinding station and the sampling station and a grain deposit subsystem transports the grain from the grain transport subsystem to a selected deposit in a grain tray after the grain has been classified.
