I-Ultrasound ibhekisela kumaza omshini (imvamisa>20 kHz) edlula ububanzi bokuzwa bendlebe yomuntu, futhi uhlobo lwefrikhwensi ephezulu (imvamisa>100 kHz) lubizwa nge-high-frequency ultrasound. Imvamisa yemishini yamanje ye-ultrasonic ngokuvamile isukela ku-20 kHz kuya ku-10 MHz. Njengobuchwepheshe obuphambili bokucubungula ukudla, i-ultrasound inezici zesenzo esimnene kanye nokuqina okuqinile. Isetshenziswa kabanzi ekudleni nakweminye imikhakha futhi inamathuba amahle okuthuthuka.
Ngokusho kwemvamisa namandla amagagasi e-ultrasonic, amagagasi e-ultrasonic angahlukaniswa abe yizigaba ezimbili: amagagasi e-ultrasonic anamandla aphansi-amandla aphansi kanye namagagasi e-ultrasonic anamandla aphansi. Phakathi kwazo, i-high-power low-frequency ultrasound (imvamisa ephakathi kuka-20 no-100 kHz) yaziwa nangokuthi i-ultrasound yamandla, enezinhlelo eziningi zokusebenza ekucutshungulweni kokudla, njengokugqugquzela i-emulsification, ukubhubhisa amaseli, inzalo kanye nokubulawa kwe-enzyme, ukuthambisa inyama nokuguqulwa kwezinto, njll. I-low-power high-frequency ultrasound (imvamisa yayo ikakhulukazi igxile ku-100 kHz kuya ku-10 MHz) ayisetshenziswa nje kuphela ekuxilongweni kwezokwelapha, kodwa futhi isetshenziswa kabanzi ekuhlaziyweni nasekuqaphelweni kwezakhiwo zokudla ezibonakalayo namakhemikhali, njengokuqina, ukuvuthwa, ushukela, i-acidity, njll.
Amagagasi e-high-frequency ultrasonic anemiphumela ehlukene yamakhemikhali neyomzimba evela kumagagasi e-ultrasonic aphansi-frequency, futhi angakwazi ukukhiqiza inani elikhulu lama-radicals mahhala asebenzayo, ngaleyo ndlela abangele ukuwohloka nokuguqulwa kwama-polymers. Lapho amagagasi e-ultrasonic esetshenziswa ekuphenduleni kwe-oxidation esixazululweni se-aqueous, amagagasi e-high-frequency ultrasonic anamandla kakhulu kunamagagasi e-ultrasonic aphansi-frequency. Ngaphansi kwezimo ezithile, njengoba i-frequency iphakama, isilinganiso samandla wangempela we-ultrasonic emandleni okufakwayo siyakhula, okungukuthi, ukusebenza kahle kokuguqulwa kuyanda, futhi i-high-frequency ultrasound ingafinyelela ukusebenza kahle okuphezulu kwe-sonochemical.
Ukusebenzisa le mpahla ye-high-frequency ultrasound nakho kungalulaza ezinye izinto ezisele eziyingozi emanzini angcolile embonini yokudla noma emaphaketheni. Inani elikhulu lama-radicals amahhala asebenzayo akhiqizwa yi-high-frequency ultrasound lingasabela ngezithako zokudla ezine-oxidized kalula, futhi ngezinga elithile lingathuthukisa izici zokusebenza zezithako ezithile zokudla.
