PROBLEM TO BE SOLVED: To provide a grain treating facility capable of efficiently treating received grain and of improving the accuracy of classifying the grain.SOLUTION: The grain treating facility comprising: a chemical component measuring part that carries out a primary measurement of components for measuring the component values of chemical components thereof without subjecting a test sample to a drying treatment, and a secondary measurement of components for measuring the component values of the chemical components thereof subsequent to subjecting a test sample to a drying treatment； and a quality discriminating part that carries out primary quality discrimination for discriminating the grain into grain of a high component value, grain of a low component value, or grain of an intermediate component value on the basis of the measurement result of the primary measurement of components, and secondary quality discrimination for discriminating the grain into grain of a high component value or grain of a low component value on the basis of the measurement result of the secondary measurement of components, is characterized in that the grain discriminated into grain of a high component value or grain of a low component value as a result of the primary quality discrimination are separately charged into a plurality of circulation type dryers and the grain discriminated into grain of an intermediate component value as a result of the primary quality discrimination is separately charged into a plurality of circulation type dryers on the basis of the result of the secondary quality discrimination.SELECTED DRAWING: Figure 1【課題】荷受けした穀物を効率よく処理することができるとともに、前記穀物の仕分け精度を向上させることができる穀物処理設備を提供することを目的とする。【解決手段】試料に乾燥処理を施すことなく化学成分の成分値を測定する１次成分測定、試料に乾燥処理を施して化学成分の成分値を測定する２次成分測定、を行う化学成分測定部と、１次成分測定の測定結果に基づいて、穀物を高成分値穀物、低成分値穀物、又は中間成分値穀物に判別する１次品質判別、２次成分測定の測定結果に基づいて、穀物を高成分値穀物又は低成分値穀物に判別する２次品質判別、を行う品質判別部とを備え、１次品質判別の結果、高成分値穀物又記低成分値穀物に判別される穀物を、複数の循環式乾燥機に仕分け投入するとともに、１次品質判別の結果、中間成分値穀物に判別される穀物については
