Indawo yokugcina ukutya kwaselwandle ebandayo

Indawo yokugcina ukutya kwaselwandle ebandayo isetyenziselwa ukugcina iimveliso zasemanzini, ukutya kwaselwandle, njl.

Ubushushu beentlobo ezahlukeneyo zokugcina ukutya kwaselwandle abufani, kodwa ngokubanzi buphakathi kwe -30 kunye ne -5°C.

Uhlu lweendawo zokugcina ukutya kwaselwandle kwindawo ebandayo:

1. Indawo yokugcina ukutya kwaselwandle ebandayo

Ubushushu bendawo yokugcina ukutya kwaselwandle buhlukile ngokwexesha lokugcina:

① Indawo yokugcina ebandayo enomlinganiselo wobushushu obuyilwe yi -5 ~ -12℃ isetyenziselwa kakhulu ukutshintshiselana okwethutyana kunye nokurhweba ngeentlanzi zaselwandle ezintsha.

Ixesha eliqhelekileyo lokugcina liziintsuku ezi-1-2. Ukuba ukutya kwaselwandle akuthunyelwanga ngaphakathi komjikelo weentsuku ezi-1-2, ukutya kwaselwandle kufuneka kufakwe kwifriji eqandisa ngokukhawuleza ukuze kuqandiswe ngokukhawuleza.

② Ifriji yefriji enobushushu obuphakathi kwe -15 ~ -20°C isetyenziselwa kakhulu ukugcina ukutya kwaselwandle okukhenkcezisiweyo ixesha elide ukusuka kwifriji ekhawulezayo. Ixesha lokugcina ngokubanzi liyi-1-180 yeentsuku.

③ Iindawo zokugcina ezibandayo ezinezi qondo lobushushu zimbini zisetyenziswa kakhulu kwaye zixhaphakile ebomini bethu. Enye yindawo yokugcina ebandayo yolwandle enomlinganiselo wobushushu obuyilwe yi -60~-45℃. Olu bushushu lungasetyenziselwa ukugcina ityhuna.

Amanzi akwiiseli zenyama ye-tuna aqala ukuba ngumkhenkce abe ziikristale kwi -1.5°C, aze amanzi akwiiseli zenyama yentlanzi abe ngumkhenkce abe ziikristale xa ubushushu bufikelela kwi -60°C.

Xa i-tuna iqala ukubanda kwi -1.5°C~5.5°C, umzimba weseli yentlanzi uba yikristale ngakumbi, nto leyo etshabalalisa i-membrane yeseli. Xa umzimba wentlanzi unyibilika, amanzi alahleka lula kwaye incasa eyahlukileyo ye-tuna iyalahleka, nto leyo enciphisa kakhulu ixabiso layo.

Ukuqinisekisa umgangatho we-tuna, ukuqandisa ngokukhawuleza kungasetyenziswa kwindawo yokugcina ebandayo eqandisa ngokukhawuleza ukuze kufinyezwe ixesha "-1.5℃ ~ 5.5℃ indawo enkulu yokwakheka kwekristale yomkhenkce" kwaye kwandiswe isantya sokuqandisa, nto leyo ekwangumsebenzi obaluleke ngakumbi ekuqandiseni i-tuna.

2. Ukugcinwa kweentlanzi zaselwandle okuqandisiweyo ngokukhawuleza

Indawo yokugcina ukutya kwaselwandle eqandisiweyo ngokukhawuleza yenzelwe ukuqandisa iintlanzi ezintsha ngokukhawuleza okwethutyana ukuze kugcinwe ubutsha bentengiselwano ukuze ikwazi ukuthengiswa ngexabiso elifanelekileyo.

Ixesha eliqhelekileyo lokubanda ngokukhawuleza ziiyure ezi-5-8, kwaye ubushushu bungama-25 ~ -30℃. Yiqandisise kakuhle ngokukhawuleza uze uyithumele kwindawo ebandayo yokugcina ukutya kwaselwandle kwi-15 ~ -20 ℃ ukuze uyigcine ngokutsha.
