PROBLEM TO BE SOLVED: To provide a γ-aminobutyric acid enrichment device capable of efficiently performing enrichment of GABA contained in grain of unhulled rice or the like and drying of the grain by using one facility.SOLUTION: A γ-aminobutyric acid enrichment device includes: a tank for storing grain a blowing tunnel which is arranged on one side of the tank and blows heated and humidified air or dry air into the tank and an exhausting tunnel which is arranged on the other side of the tank and exhausts the heated and humidified air or dry air from the interior of the tank. In the tank of the γ-aminobutyric acid enrichment device a plurality of blowing pipes having porous walls through which the heated and humidified air or dried air are blown from the blowing tunnel and a plurality of exhausting pipes having porous walls through which the heated and humidified air or dried air are exhausted to the exhausting tunnel are transversely provided. Therein, a first cover body is provided on an outlet side end part of the exhausting pipes through which the heated and humidified air or dried air are exhausted.COPYRIGHT: (C)2015,JPO&INPIT【課題】本発明は、籾米等の穀粒に含まれるギャバの富化と前記穀粒の乾燥とを、一つの設備を利用して効率よく行うことができるγ-アミノ酪酸富化装置を提供することを目的とする。【解決手段】本発明は、穀粒を貯留するタンクと、該タンクの一側に配設されて前記タンク内へ加温加湿空気又は乾燥空気を送風する送風洞と、前記タンクの他側に配設されて前記タンク内から前記加温加湿空気又は乾燥空気を排風する排風洞とを備え、前記タンク内には、前記送風洞から前記加温加湿空気又は乾燥空気が送風される多孔壁を有する複数の送風管と、前記排風洞へ前記加温加湿空気又は乾燥空気を排風する多孔壁を有する複数の排風管とを横設してなるγ-アミノ酪酸富化装置において、前記排風管の前記加温加湿空気又は乾燥空気を排風する出口側端部に、第一の蓋体を設けることを特徴とする。【選択図】図1
