PROBLEM TO BE SOLVED: To solve a problem that in a seed disinfection equipment of the form which adds medical solution to the seed rice and carries out disinfection and drying, supplying of the medical solution immediately after a disinfection start is not stabilized easily, drying of the disinfected seed rice is hard to be performed, and when the supplied amount of the seed rice is small, uniform medical solution penetration is frequently difficult for the seed rice.SOLUTION: In the seed disinfection equipment, there are arranged a disinfection equipment 2 which disinfects the seed supplied from a hopper 1 by spraying the medical solution, a drier 3 which carries out ventilation drying of the seed disinfected, and a shipping weighing apparatus 4 which carries out weighing and shipment of the seed sent out from the drier 3, wherein, between the steps of the drier 3 and the shipping weighing apparatus 4, a switching device 5 is prepared which switches the conveyance returning the seed conveyed from the drier 3 to the disinfection equipment 2 or to the drier 3.COPYRIGHT: (C)2014,JPO&INPIT【課題】 薬液を種籾に添加して消毒乾燥する形態の種子消毒装置においては、特に消毒開始直後の薬液の供給が安定し難く、消毒種籾の乾燥が行われ難く、又、種籾の供給量が少ない場合には種籾に均一な薬液浸透の難しい場合がある。【解決手段】 ホッパー1から供給される種子を薬液散布のもとに消毒する消毒装置2と、この消毒された種子を通風乾燥する乾燥装置3と、この乾燥装置3から送出される種子を計量出荷する出荷計量装置4とを配置し、これら乾燥装置3と出荷計量装置4との行程間には、前記乾燥装置3から搬出された種子を前記消毒装置2へ戻すか、又はこの乾燥装置3へ戻すように切替搬送する切替装置5を設ける。【選択図】 図1
