Excerpts from the report Summary: A mechanical method for splitting peanut kernels and arranging the halves (the cotyledons) with their flat or inner surfaces exposed for visual examination as a part of official sample inspection, has been devised. A method has been developed also to arrange the peanut halves for visual inspection of their rounded or outer surfaces. These methods have been incorporated into flow -type machines, now used in official inspection procedure as aids in splitting and examining samples of peanuts for concealed damage. The same or similar machines are being used also to inspect samples from peanuts which have been split open during the shelling operation in commercial shelling plants. These machines save nearly half a man-hour of labor per 1,000-gram sample inspected. Similar techniques also may be used on picking tables in peanut processing plants or for the internal inspection of other dicotyledonous seeds.
