PROBLEM TO BE SOLVED: To provide a rice seed sorter in which rice seeds are selected without depending on a specific gravity, and the yield is good.SOLUTION: A rice seed sorter is provided for: removing rice seeds of rice mixed in rice seeds of glutinous rice and generated by hybridization of glutinous rice with non-glutinous rice pollens, and the rice seeds of the non-glutinous rice or removing the rice seeds of the rice mixed in the rice seeds of the non-glutinous rice and generated by the hybridization with the glutinous rice pollens of the non-glutinous rice, and the rice seeds of the glutinous rice. Accordingly, the rice seed sorter includes: irradiation means 7 for irradiating transferred rice seeds W with light along a predetermined transfer path G detection means 8 for receiving transmitted light transmitted through the rice seeds W and detecting the transmission light intensity determination means for determining rice seeds F to be removed, based on the transmission light intensity detected by the detection means 8 and removal means 10 for injecting air in order to remove rice seeds F to be removed determined by the determination means from the transfer path G.COPYRIGHT: (C)2015,JPO&INPIT【課題】比重によらず種籾を選別し、歩留りが良い種籾選別装置を提供する。【解決手段】種籾選別装置は、モチ米の種籾の中に混在している、モチ米のウルチ米花粉との交雑により発生する米の種籾及びウルチ米の種籾を除去する、または、ウルチ米の種籾の中に混在している、ウルチ米のモチ米花粉との交雑により発生する米の種籾及びモチ米の種籾を除去する。このために、種籾選別装置は、所定の移送経路Gに沿って移送されている種籾Wに光を照射する照射手段7と、種籾Wを透過した透過光を受光して透過光の強度を検出する検出手段8と、検出手段8により検出された透過光の強度に基づいて、除去対象の種籾Fを判別する判別手段と、判別手段により判別された除去対象の種籾Fを移送経路Gから取り除くためにエアーを噴射する除去手段10と、を備える。【選択図】図1
