pahu hau hau kai kai

Nānā nui:

He ʻenehana hoʻoheheʻe meaʻai hou i nā makahiki i hala iho nei.ʻO ka mahana maʻamau o ka nitrogen wai he -195.8 ℃, a ʻike ʻia ʻo ia ka mea ʻoi aku ka maikaʻi o ke kaiapuni, ʻoi aku ka maikaʻi a me ka hoʻokele waiwai.Ke hoʻopili ʻia ka nitrogen wai me ka iʻa, ʻoi aku ka ʻokoʻa o ka mahana ma luna o 200 ℃, a hiki ke hoʻokuʻu koke ʻia ka meaʻai i loko o nā minuke 5. ʻO ke kaʻina hana hoʻoheheʻe wikiwiki e liʻiliʻi loa nā ʻāpana hau hau o ka iʻa, pale i ka nalowale o ka wai, pale i ka luku. ʻO ka bacteria a me nā microorganisms ʻē aʻe, hoʻolilo i ka meaʻai me ka ʻole o ka discoloration oxidative a me ka momona rancidity, a mālama i ke kala kumu, ʻono a me nā meaʻai o ka iʻa, no laila hiki i ka maloʻo lōʻihi ke hōʻoia i ka ʻono maikaʻi loa.

ʻO ka meaʻai iʻa wai hau hau ka mea mua e hoʻohana ʻia i ka hoʻoheheʻe ʻana i ka iʻa kiʻekiʻe ma muli o kona hoʻokē ʻai ʻana, lōʻihi ka mālama ʻana, haʻahaʻa haʻahaʻa kumu kūʻai hoʻokomo, haʻahaʻa haʻahaʻa hana, ʻaʻohe hoʻohana ikehu, ʻaʻohe walaʻau a ʻaʻohe mālama.Hiki ke wānana ʻia e hoʻololi mālie ka ʻenehana hoʻoheheʻe cryogenic wai i ka ʻenehana kuʻuna mechanical refrigeration a me ka ʻenehana regrigeration, kahi e lawe mai ai i nā loli hohonu i ka hana o ka pahu hau kuʻuna.

Nā hiʻohiʻona huahana:

○ Hoʻohana ʻia ka ʻenehana insulation multi-layer kiʻekiʻe e hōʻoia i ka haʻahaʻa haʻahaʻa haʻahaʻa o ka hoʻoheheʻe ʻana o ka wai nitrogen (<0.8%) a me ke kumu kūʻai haʻahaʻa loa.

○ Hiki i ka mākaʻikaʻi naʻauao a me ka ʻōnaehana hoʻokele o ka pahu wai nitrogen ke nānā i ka mahana a me ka pae wai o ka pahu iʻa i ka manawa maoli, ʻike i ka hoʻopiha piha ʻana, ka hoʻāla ʻana no nā hewa like ʻole, a me ka hōʻoia i ka hana palekana o nā lako.I ka manawa like, hāʻawi ia i ka ʻōnaehana hoʻokele waiwai mālama, e hoʻomaʻamaʻa i ka hoʻokele ʻana o nā waiwai ma waho o ka hale kūʻai a me ka hale kūʻai.

○ Hana ʻia nā pūpū o loko a me waho i ke kila kila kila e hōʻoia ai i ke ola o ka huahana ma mua o 10 mau makahiki.

○ Ua hoʻolālā ʻia ke ʻano o ka pā i loko e hoʻomaʻamaʻa i ke komo ʻana i ka iʻa.Hiki ke hoʻolako ʻia kekahi mau hiʻohiʻona me ka hoʻololi ʻana i ka uila e ʻike ai i ke komo ʻakomi.

○ Hiki ke mālama ʻia i loko o ke kinoea a me ka wai e hōʻoia i ka hiki ʻana o ka wela o ka waha pahu i -190 degere C.

Nā mea maikaʻi o ka huahana:

○ Haʻahaʻa evaporation rate o ka wai nitrogen
ʻO ka ʻenehana insulation multilayer kiʻekiʻe e hōʻoia i ka haʻahaʻa haʻahaʻa haʻahaʻa o ka naikokene wai a me ke kumu kūʻai haʻahaʻa.

○ Mālama ka ʻenehana hou i ka ʻono kumu
Liquid nitrogen wikiwiki manuahi, ai ice crystal particles ka liʻiliʻi loa, e hoʻopau i ka nalowale o ka wai, keakea i ka bacteria a me nā microorganisms ʻē aʻe e hōʻino ai i ka meaʻai, no laila ʻaʻohe mea ʻai i ka discoloration a me ka rancidity wale nō.

○ Pūnaehana nānā naʻauao
Hiki ke hoʻolako ʻia me ka ʻōnaehana mākaʻikaʻi naʻauao, ka nānā ʻana i ka pūnaewele manawa maoli o kēlā me kēia pahu pahu, ke kiʻekiʻe kiʻekiʻe o ka wai, a me nā mea ʻē aʻe, hiki ke hoʻomaopopo pū i ka hoʻopiha piha ʻana, nā ʻano ala āpau hewa. ma waho o ka mālama mālama ʻana.
