PROBLEM TO BE SOLVED: To enable speedy and high precision temperature control, when the temperature of the warm water is controlled in the warm water disinfection tank.SOLUTION: This warm water disinfection apparatus is equipped with a warm water heating means for heating the warm water in the warm water disinfection tank, a warm water temperature-detecting mean for detecting the temperature of the warm water in the disinfection tank, a controlling means for controlling the warm water-heating means so that the temperature of the warm water in the disinfection tank may become a proper one according to the detected value of the warm water temperature, and a warm water-ejecting means for ejecting the warm water toward a vessel containing seeds and moving inside the warm water disinfecting tank. The warm water heating means has heat exchanging pipes on the bottom of the warm water disinfection tank, the warm water-ejecting means cause the warm water in the warm water disinfection tank to circulate through a pump and is ejected from a plurality of the ejection nozzles formed on the circulation pipes at a prescribed interval.COPYRIGHT: (C)2008,JPO&INPIT【課題】温湯消毒槽における温水の温度を制御するにあたり、スピーディで精度の高い温度制御を可能にする。【解決手段】温湯消毒槽内の温水を加温する温水加温手段と、温湯消毒槽内の温水温度を検出する温水温度検出手段と、前記温水温度検出手段の検出値によって前記温湯消毒槽内の温水温度が適正温度となるように、温水加温手段を制御する制御手段と、温湯消毒槽内を移動する種収納容器に向けて温水を噴出する温水噴出手段とを備え、温水加温手段は、温湯消毒槽の底部に配管される熱交換パイプを備え、温水噴出手段は、温湯消毒槽内の温水をポンプを介して循環させて循環パイプに所定間隔を存して設けた複数の噴出口から温水を噴出する。【選択図】図7
