Abstract: An object of the present invention is to improve the quality level discrimination accuracy of the grain G by a grain quality level discrimination device. The device includes an optical unit 3 that emits light to the grain G, receives reflected and/or transmitted light from the grain G by a photosensor, and obtains information for discrimination of the quality level of the grain G from the upper and lower surface side of the grain G, and a quality level discrimination unit 7 that discriminates the quality level of the grain G on the basis of the information. The information on the upper and lower surface sides can be acquired by one optical unit at the same time so that the divergence therebetween due to the displacement or variation of the attitude of the grain G can be avoided. The reference plate for the correction of the information is placed outside of the moving path of the grain G to prevent it from soiling or damaging. Thus the deterioration of information can be avoided. Further, a reference plate especially for the information to be obtained from the side surface of the grain G may be provided for enhancing the accuracy of the side surface information. Thus the quality level discrimination accuracy can be improved further.

Abstract: A paddy discriminator includes a downflow gutter in which mixed grains including paddy and brown rice are aligned and flow down, a light emission source that irradiates the mixed grains discharged from the downflow gutter with light, and light receiving means capable of receiving reflected light and transmitted light from the mixed grains irradiated with light by the light emission source, wherein the light emission source includes first illumination means that is provided on a light receiving means side of the mixed grains and is capable of irradiating the mixed grains with light of a red component, and second illumination means that is provided on a side away from the light receiving means of the mixed grains and is capable of irradiating the mixed grains with light of a green component.

Abstract: Controller of an optical sorter is configured to receive an input of a candidate for a target quality condition regarding an allowable mix rate of defective products in sorting targets discharged from the optical sorter as acceptable products, receive an input of quality information indicating a mix rate of the defective products regarding at least a part of the sorting targets, simulate, based on the information, a sorting result regarding a quantity and/or a yield of the sorting targets discharged as the acceptable products that is expected to be acquired when sorting is conducted by a sorting device to achieve the candidate for the target quality condition and output a result of the simulation, receive an input of a final target quality condition to be employed when conducting the sorting, and conduct the sorting based on a sorting control parameter that allows the final target quality condition to be achieved.
