ʻO ka ʻoki ʻana i ka meaʻai kani ultrasonic he mea pōʻino i ke kino kanaka. A i nā makahiki i hala iho nei, ua hoʻohana nui ʻia ka ultrasound i ka ʻoihana meaʻai.
ʻO ka noi kani ultrasonic no ka ʻoki ʻana i ka meaʻai: ʻaʻole pono nā pahi ʻoi, ʻaʻohe koi nui e koi ʻia, a ʻaʻole e ʻoki ʻia ka mea ʻoki a ʻeha paha. Ke hana nei ka ʻoki ʻoki i ka vibration ultrasonic, ʻoi aku ka liʻiliʻi o ka friction resistance, a ʻo ka mea e ʻoki ʻia ʻaʻole maʻalahi ke pili i ka lau. Loaʻa iā ia ka hopena ʻokiʻoki i nā meaʻai paʻa, paʻa a elastic, ʻoi aku ka maikaʻi. I ka manawa like o ka ʻoki ʻana, he hopena fusion ka ʻāpana ʻoki. Hoʻopaʻa ʻia ke kahua ʻoki i ka lihi e pale ai i ka hemo ʻana o ka ʻiʻo meaʻai i ʻoki ʻia. ʻO ka mīkini ʻoki kani kani ka mea hoʻohana i ka ikehu nalu no ka ʻoki ʻana a me ka hana ʻana, a ua ʻike ʻia me ka hoʻohana ʻole ʻana i nā kihi ʻoki kuʻuna.
ʻOki kuʻuna: Hoʻohana ka ʻoki kuʻuna i ka pahi me ka ʻoi ʻoi e kaomi i ka meaʻai e ʻoki ʻia. Hoʻopili ʻia ke kaomi ma ka lihi o ka maka, a he nui loa ke kaomi, ʻoi aku ma mua o ka ikaika ʻoki o ka meaʻai i ʻoki ʻia, a huki ʻia ka paʻa molekala o ka meaʻai a ʻoki ʻia. Ma muli o ka huki ʻana o ka meaʻai me ke kaomi ikaika, ʻoi aku ka ʻoi o ka ʻoki ʻoki o ka mea ʻoki, a ʻo ka mea ponoʻī ma lalo o ke kaomi kiʻekiʻe. ʻAʻole maikaʻi no ka ʻoki ʻana i ka meaʻai palupalu a lohi, a ʻoi aku ka paʻakikī o ka meaʻai paʻa.
No laila, ke hoʻohālikelike ʻia me ka ʻoki kuʻuna, ʻike ʻia nā pōmaikaʻi o ka ʻoki ʻoki ultrasonic, ʻo ia ke kumu i hoʻohana nui ʻia ai kēia ʻano i ka ʻoihana meaʻai. Ma waho aʻe o ka ʻoki ʻana i ka meaʻai kani ultrasonic, nā noi ʻē aʻe i ka ʻoihana meaʻai e komo pū ana: ka hoʻomaʻemaʻe kani ultrasonic, ka hoʻomaʻemaʻe ʻana i ke kani ultrasonic, ka sterilization ultrasonic, ka emulsification ultrasonic, ka crystallization ultrasonic, ka maloʻo ultrasonic, etc.
