Description

本発明は、玄米又は白米等の被選別穀粒を粒径、粒状により選別する穀粒選別装置に関するものである。   The present invention relates to a grain sorting device that sorts grains to be sorted such as brown rice or white rice by particle size and granularity.

籾摺機で籾摺りした玄米には、粒径の小さい未熟粒が混在していたり、また玄米を精米機で精白した白米には、精米によって穀粒の表面が摩擦や研削作用を受けるところから、穀粒の一部に破砕が生じたり変形が生じることが避けらず、未熟粒のほかに破砕粒や変形粒も混在している。このため、従来から、玄米又は精白米を粒状選別して屑粒を除去する穀物選別装置として回転する選別網筒を備えた構成のものが用いられており(特開2006−26466公報、特開2008−6321公報、特開平10−156199号公報参照)、選別網筒を固定してその内部で可撓性板の撹拌翼を回転させるものも開発されている(特開2007−152351公報、特開2005−238203公報、特開2003−326180公報参照)。   Unpolished rice with a small particle size is mixed in brown rice milled with a rice bran machine, and the surface of the grain is subjected to friction and grinding action by polished rice in white rice milled brown rice with a rice milling machine, A part of the grain is crushed or deformed, and in addition to the immature grains, crushed grains and deformed grains are also mixed. For this reason, the thing of the structure provided with the rotation sorting net | cylinder is conventionally used as a grain sorter which carries out the granular sort of brown rice or polished rice, and removes a waste grain (JP, 2006-26466, A) 2008-6321 and Japanese Patent Laid-Open No. 10-156199), and a method in which a sorting screen cylinder is fixed and a stirring blade of a flexible plate is rotated inside is also developed (Japanese Patent Laid-Open No. 2007-152351, in particular). JP 2005-238203 A, JP 2003-326180 A).

また、前掲の特開2007−152351公報、特開2005−238203公報、特開2003−326180公報に記載されている穀粒選別装置にあっては、被選別穀粒を投入するための揚穀機(昇降機)を併設することが行われており、なお、選別装置本体に昇降機を併設することについては、特開2007−98276公報、特開2007−21381公報及び特開2007−21382公報にそれぞれ記載されている。
