ʻO kaʻoihana meaʻai kaʻoihana ola nui o nā kānaka, a ke hoʻomau neiʻo ia i ka "hoʻoulu" me ka hoʻonuiʻana i nā pono kanaka. ʻO ke koho ʻana i ka meaʻai a ke kanaka ka mea e pono ai ka meaʻai. Eia naʻe, i nā manawa he nui ʻaʻole hiki i nā waiwai o ka meaʻai ke hoʻokō i nā pono o ka hoʻoponopono hou ʻana, e koi ana i ka hoʻololi a me ka hana. Me ka hoʻololi ʻole ʻana i kona ʻano, ua hana nui ka ʻenehana hana kino i ka ʻoihana meaʻai.
ʻO ka ʻenehana Cavitation kahi ʻenehana hoʻomaʻamaʻa kino meaʻai, e hoʻohana ana i ka ikaika hopena ikaika i hana ʻia e ka hāʻule ʻana o nā ʻōpū cavitation e hoʻomaikaʻi i ka hopena jet erosion. I ka wā o ke kaʻina hana cavitation, ʻo ka manawa e hāʻule ai ka puʻupuʻu cavitation e hoʻopuka i ka wela kiʻekiʻe kiʻekiʻe a me ke kaomi kiʻekiʻe, i hui pū ʻia me nā hawewe haʻalulu ikaika, microjets, turbulence, a me nā ikaika shear kiʻekiʻe, e hoʻololi i ke ʻano o ka mea a hoʻololi i ke ʻano o ka huahana. ʻO nā hiʻohiʻona kaʻina hana, e like me ka solubility, emulsification, rheology, a me nā mea ʻē aʻe. I kēia manawa, ʻelua ʻano nui o nā noi maʻamau, ʻo ka ʻenehana ultrasonic a ʻo ka ʻenehana hydraulic cavitation kekahi.
Ultrasonic cavitation ʻenehana
ʻO ke kani kani he hawewe kani me ke alapine (frequency) ʻoi aku ka nui ma mua o 20kHZ, ka mea i hoʻokumu i ka haʻalulu mechanical o nā ʻāpana media i loko o ke kikowaena, a laila e hoʻopili ai i ka hawewe acoustic a me ka waena. Ke ʻoi aku ka mamao o ka molecular wai ma mua o ka mamao molekala koʻikoʻi o ka wai, hana ʻia nā lua, a aia nā puka i ka hoʻomau mau ma lalo o ka hana a nā hawewe kani) a hāʻule paha. Ke emi iho nei ka adiabatic bubble transient a hāʻule, hiki i ka liʻiliʻi liʻiliʻi a puni ka pahu cavitation ke hoʻoulu i ka wela kiʻekiʻe a me ke kaomi kiʻekiʻe, i hui pū ʻia me nā nalu haʻalulu ikaika, no laila e hana i nā hopena kino a me nā hopena kemika.
ʻenehana cavitation hydraulic
ʻO ka Hydraulic cavitation ke ʻano o ka hele ʻana o kahi wai i loko o kahi mea throttle (e like me ka orifice plate, venturi, etc.), ma muli o ke keakea ʻana o ka mea i ka wai, ʻoi aku ka nui o ke kahe o ka wai a emi ke kaomi. Ke hoʻemi ʻia ke kaomi wai i ke kaomi mahu a i ʻole ke kaomi maikaʻi ʻole, ma muli o ka noho ʻana o nā koina kinoea hiki ʻole ke hoʻoheheʻe ʻia i loko o ka wai, e hoʻoheheʻe ka wai a hoʻohua i ka nui o nā pahu cavitation. Me ka hoʻihoʻi wikiwiki ʻana o ke kaomi a puni ka wai, ua pohā koke nā ʻōpū cavitation E hoʻopau, i loli nā ʻano o nā mea pili. Ma o ka nui o ka cavitation bubble generation a me nā hana luku, hiki i ka mea ke hoʻokō i ka hopena i makemake ʻia. ʻO ka hana o ka ʻenehana hydraulic cavitation e like me ka hawewe kani ultrasonic. ʻOi aku ka haʻahaʻa o kona ikaika ma mua o ka hawewe kani ultrasonic, akā ʻoi aku ka kiʻekiʻe o kāna cavitation rate a me ka ikaika o ka ikehu ma mua o ka hawewe kani ultrasonic.
Ua like nā hopena o ka ultrasonic cavitation a me ka hydraulic cavitation, akā aia nā ʻokoʻa i nā hiʻohiʻona noi. Ma ke ʻano o ka noi, ʻoi aku ka nui o ka hoʻohana ʻana o ka ultrasonic cavitation, aʻo ka hydraulic cavitation e pili wale ana i nā mea "wai". Ua ulu wikiwiki ka ʻenehana cavitation i nā makahiki i hala iho nei. Nui nā ʻano hana hou e like me ka cavitation māmā a me ka cavitation particle ke hoʻololi ʻia nei i huahana maoli. Manaʻo ʻia e lilo ia i kekahi o nā ʻano hana koʻikoʻi i ka ʻoihana meaʻai i ka wā e hiki mai ana.
