I ke kaʻina ʻokiʻoki, ʻike pinepine mākou i nā pilikia he nui, e like me ka pololei o ka ʻoki ʻana, ka paʻa o nā waiwai kino o ka huahana hope, ka maʻalahi o ka ʻoki ʻoki, ka paʻakikī o ka hoʻokaʻawale ʻana i ka mea ʻoki mai ka mea, a me ka hoʻokaʻawale ʻana o ka ʻoki ʻoki a me nā mea i ka wā kaʻawale. Ke maopopoʻole nāʻano o nā mea, he mea paʻakikī iā mākou ke hoʻokō i nā koi i luna.
No ka laʻana, no nā mea me ka paʻakikī kiʻekiʻe, ka brittleness ikaika, a me ka viscosity ikaika, paʻakikī ke ʻano o ka ʻoki kuʻuna. Ke piʻi nei ka maopopo ʻole o nā mea huahana, ʻoi aku ka paʻakikī o ka ʻoki ʻana i ka hana. ʻO ka ʻoki ʻana i ka meaʻai kani ultrasonic he optimization o ka ʻoki kuʻuna. ʻAʻole hoʻonui ka ʻoki ʻoki ʻana i ka meaʻai kani ultrasonic wale nō, akā ke holomua nui nei i ka hoʻomaikaʻi ʻana i ke ʻano, ke ʻano a me ka hana o ka meaʻai.
ʻOiai no ka hapa nui o nā huahana, hiki i ka ʻoki ʻana i ka meaʻai ultrasonic ke hōʻemi i ka ikaika ʻoki i koi ʻia no ke kaʻina ʻokiʻoki, akā no kekahi mau huahana, noʻonoʻo ʻia ka mea. ʻO ka maʻamau ka mea ʻoki ma waena o 0.1-1.0. Inā ʻoe e aʻo i ke ʻano macro a me nā waiwai mechanical o ka meaʻai i ke kaʻina ʻoki, e noʻonoʻo i nā ʻano mea no ka ʻoki ʻana i ka meaʻai. No laila, e hoʻokaʻawale i nā ʻano mea ʻekolu.
1. No nā meaʻaʻahu a me nā mea paʻa, e like me nā meaʻai momona momona, cheese, etc. ʻO kēia mau meaʻai iʻikeʻia e kahiʻano porous a paʻa. I ke kaʻina hana ʻoki kuʻuna, hana pinepine ʻia ka nui o ka friction, a ʻo ka nui o ka friction e pili ana i ka viscosity o ka mea. Hiki i ka ʻoki kani kani ke hōʻemi i ka ikaika o ka pilina ma waena o ka mea ʻoki a me ka mea i ka wā o ke kaʻina ʻokiʻoki, a laila e pale aku i ka deformation plastic. Ma ka ʻaoʻao ʻē aʻe, piʻi nui ka hoʻohana ʻana i ka ikehu o kēia hana paʻa a me ka porous i ka wā o ka ʻoki ʻana.
2. No nā meaʻai porous, e like me ka berena, nā keke, nā marshmallows a me nā meaʻai ʻē aʻe me nā ʻano like, ʻo kā lākou hiʻohiʻona maʻamau he ʻano like me ka sponge. Eia kekahi, he mea maʻalahi loa ka hoʻopili ʻana a me ka deformed. Inā hoʻohana ʻia ka mea ʻoki kuʻuna, hiki ke hiki wale i kahi hapa o ka māwae. Ina e oki hou ia, e wili a nahaha. Akā inā ʻoe e hoʻohana i ka ʻoki ultrasonic, e loaʻa iā ʻoe nā hopena maikaʻi. No ka mea hiki i ka ʻoki ultrasonic ke hōʻemi i ka friction i hana ʻia i ka wā o ke kaʻina ʻoki, hiki ke hoʻopau ʻia ka hana ʻoki me ka ikaika ʻoki liʻiliʻi. ʻO ka hope, loaʻa kahi ʻili ʻoki maʻemaʻe a maʻemaʻe. Ke hoʻohālikelike ʻia me ka ʻokiʻoki ʻana i nā mea momona, ʻoi aku ka liʻiliʻi o ka hopena o ka friction ma ke kaʻina ʻoki i ka wā o ka ʻoki ʻana i nā mea porous. No ka mea, ʻoi aku ka liʻiliʻi o ka wahi pili maoli ma waena o ka mea ʻoki a me ka mea i ka wā e ʻoki ai ma mua o ka ʻāpana geometric o ka mea. Eia kekahi, i ke kaʻina hana o ka mea hana i ke komo ʻana i ka mea, pono ka mea porous i ka ikehu ma mua o ka mea paʻa.
3. ʻO ka ʻiʻo holoholona a me nā ʻiʻo mea kanu, he ʻano keena a pau, me nā ʻano like ʻole a i ʻole nā haku mele. Ma muli o ka hoʻokumu ʻana o kahi kiʻiʻoniʻoni lubricating a me kona ʻano wai kiʻekiʻe, ʻaʻole koʻikoʻi ka pale ʻana i ka friction i ka wā ʻoki. ʻO ka paʻakikī o nā mea paʻa e hoʻoholo i ka ikaika o kaʻoki. No ka hapa nui o nā ʻiʻo mea kanu, ua hoʻemi nui ʻia ka ikaika ʻoki pono e ka ultrasonic excitation. Akā no nā hale filamentary paʻakikī (e like me ka ʻiʻo ʻiʻo), hiki mai kekahi mau pilikia. Pono kēia i ka hau, ka hoʻoikaika ʻana a i ʻole ke kuke ʻana e hoʻōla pono i ka hale. Me kēia mau lāʻau lapaʻau, hiki ke hoʻokō ʻia ke kumu o ka hōʻemi ʻana i ke kūpaʻa ʻoki.
