Ultrasound inoreva mechanical wave (frequency>20 kHz) inodarika kunzwikwa kwenzeve yemunhu, uye mhando yepamusoro-soro (frequency>100 kHz) inonzi high-frequency ultrasound. Iyo frequency yeazvino ultrasonic midziyo inowanzo muhuwandu hwe20 kHz kusvika 10 MHz. Seyepamusoro pekugadzira chikafu tekinoroji, ultrasound ine hunhu hwekunyorova chiito uye yakasimba pertinence. Inoshandiswa zvakanyanya mukudya nemimwe minda uye ine tarisiro huru yebudiriro.
Zvinoenderana nehuwandu uye simba remafungu e ultrasonic, mafungu e ultrasonic anogona kukamurwa kuita mapoka maviri: high-power low-frequency ultrasonic waves uye low-power high-frequency ultrasonic waves. Pakati pavo, high-power low-frequency ultrasound (frequency pakati pe20 ne100 kHz) inonziwo simba re ultrasound, iro rine maitiro akawanda ekushandiswa mukugadzirwa kwezvokudya, zvakadai sekusimudzira emulsification, kuparadza masero, sterilization uye kuuraya enzyme, kunyorovesa nyama uye kugadzirisa zvinhu, nezvimwewo. Low-simba high-frequency ultrasound (nguva yaro inonyanya kuiswa mu 100 kHz kusvika 10 MHz) haingoshandiswi chete mukuongororwa kwechiremba, asiwo inoshandiswa zvakanyanya mukuongorora uye kutarisa kwezvokudya zvemuviri nemakemikari zvinhu, zvakadai sekuoma, kukura, shuga, acidity, nezvimwewo.
Yakakwira-frequency ultrasonic mafungu ane akasiyana emakemikari uye emuviri mhedzisiro kubva pasi-frequency ultrasonic mafungu, uye anogona kugadzira huwandu hukuru hweanoshanda emahara radicals, nekudaro achikonzera kushatisa uye kugadziridzwa kwemapolymers. Kana mafungu e ultrasonic anoshandiswa kune oxidation reaction mune aqueous solution, high-frequency ultrasonic waves inowedzera simba-inoshanda kupfuura yakaderera-frequency ultrasonic waves. Pasi pemamwe mamiriro ezvinhu, sezvo nguva yakawanda inokwira, chiyero cheiyo chaiyo ultrasonic simba kune simba rinopinza rinowedzera, kureva, kushanduka kwekugadzirisa kunowedzera, uye high-frequency ultrasound inogona kuwana sonochemical inobudirira.
Kushandisa iyi pfuma ye-high-frequency ultrasound inogonawo kukanganisa zvimwe zvakasara zvinokuvadza muindasitiri yezvekudya tsvina yemvura kana kurongedza. Nhamba huru yeanoshanda emahara radicals inogadzirwa ne-high-frequency ultrasound inogona kuita nezviri nyore oxidized chikafu chekudya, uye kune imwe nhanho inogona kuwedzera mashandiro ezvimwe zvinhu zvekudya.
