Abstract
Description
本出願は、2020年6月17日に出願された、「Destruction Of Airborne Pathogens,And Microorganisms On Grains And Dried Food Using Ultrasound」のための、米国仮特許出願番号63/040,259の利益を主張し、その特許出願の内容全体がこれにより、具体的に、それが開示し、および教示するものすべてについて本明細書中に参照により組み込まれる。
容器12の底部18上の4gの小麦穀粒により、厚さ約1/4インチの層が形成された。5~10層の厚さが効果的に機能することが予想される。上記穀粒は次いで、サルモネラコレラスイス(14028、ソース:BDダイアグノスティックシステムズ(BD Diagnostic Systems)社 商品名:穀物の汚染に関する伊藤忠(ITOCHU)手順による、BD BBL(商標) QualiSwab(商標)品質管理生物)により、人工的に汚染された。同一のサンプルが、比較のための基準サンプルとして汚染された。使用された振動周波数、振幅、FM変調等は、最適化されなかったが、穀物に対する穀物の複数の衝撃が明らかに生じた。1つのサンプルは次いで、10分間、図2中に表された振動汚染方法にかけられた。対照サンプルには超音波照射されなかった。超音波照射に続いて、いずれのサンプルも、蒸留水によりすすがれ、および培養された。各テストは3回繰り返され、報告された数値は、単位がCFU(コロニー形成単位)である。第1の列は対照サンプルからの数値を示し、および第2の列はバルク穀物超音波照射の結果を示す。
サルモネラ菌の第2の培養物が調製され、第2のバッチの穀物が別個に感染された。
として表され得る。ここで、Poは圧力振幅であり、kは波長定数であり、λは波長であり、tは時間であり、xは変換器およびリフレクタ内の局所位置であり、Vpは粒子体積であり、βfは流体圧縮性であり、ならびにφは材料定数である。たとえば、K.YosiokaおよびY.Kawasimaによる「Acoustic Radiation Pressure on a Compressible Sphere」,Acustica,Vol.5,pp.167-173,1955を参照されたい。
により得られる。ここで、βfおよびβpはそれぞれ、流体媒質(空気)および粒子の材料圧縮性である。たとえば、L.A.Cruzによる「Acoustic Force on a Liquid Droplet in an Acoustic Stationary Wave」,J.of the Acoustical Society of America,Vol.50,pp.157-163,1971を参照されたい。
