Abaningi bajwayelene nokusetshenziswa okuvamile kwe-nitrogen ewuketshezi ezindaweni zokucwaninga nasezibhedlela ukuze kugcinwe amasampula. Kodwa-ke, ukusetshenziswa kwayo empilweni yansuku zonke kuyanda, okuhlanganisa nokusetshenziswa kwayo ekulondolozeni ukudla kwasolwandle okubizayo ukuze kuthuthwe amabanga amade.
Ukulondoloza ukudla kwasolwandle kuza ngezindlela ezahlukene, njengalezo ezivame ukubonwa ezitolo ezinkulu, lapho ukudla kwasolwandle kulele eqhweni ngaphandle kokubanda khona. Kodwa-ke, le ndlela iholela esikhathini esifushane sokulondolozwa futhi ayifanele ukuthuthwa ibanga elide.
Ngokuphambene nalokho, ukudla kwasolwandle okuqandisa nge-flash nge-nitrogen ewuketshezi kuyindlela yokuqandisa esheshayo nephumelelayo ekhulisa ubusha kanye nenani lokudla okunomsoco kokudla kwasolwandle.
Lokhu kungenxa yokuthi izinga lokushisa eliphansi kakhulu le-nitrogen ewuketshezi, elifinyelela ku--196 degrees Celsius, livumela ukubanda okusheshayo kokudla kwasolwandle, kunciphisa ukwakheka kwamakristalu amakhulu eqhwa ngesikhathi sokubanda, okungabangela umonakalo ongadingekile wamangqamuzana. Ligcina ngempumelelo ukunambitheka kanye nokuthungwa kokudla kwasolwandle.
Inqubo yokusebenzisa i-nitrogen ewuketshezi ukuze kuqandiswe ukudla kwasolwandle ilula. Okokuqala, kukhethwa ukudla kwasolwandle okusha, kususwe izingxenye ezingafuneki kanye nokungcola, bese kuhlanzwa kahle. Ngemuva kwalokho, ukudla kwasolwandle kufakwa esikhwameni sepulasitiki esivaliwe, kukhishwe umoya, bese isikhwama sicindezelwa ngangokunokwenzeka. Isikhwama sibe sesifakwa ethangini le-nitrogen ewuketshezi, lapho sihlala khona kuze kube yilapho ukudla kwasolwandle kuqandisiwe ngokuphelele futhi kulungele ukusetshenziswa kamuva.
Isibonelo, amathangi okugcina i-nitrogen yoketshezi lokudla kwasolwandle eShengjie, asetshenziswa kakhulu ekuqandeni ukudla kwasolwandle okusezingeni eliphezulu, anokupholisa okusheshayo, isikhathi eside sokulondolozwa, izindleko zokutshalwa kwezimali kanye nokusebenza kwemishini eziphansi, ukusetshenziswa kwamandla okungekho, ukungabi nomsindo, ukunakekelwa okuncane, ukulondolozwa kombala wokuqala wokudla kwasolwandle, ukunambitheka, kanye nokuqukethwe okunomsoco.
Ngenxa yokushisa okuphansi kakhulu kwe-nitrogen ewuketshezi, kumele kuthathwe izinyathelo zokuphepha eziqinile lapho kusingathwa ukuze kugwenywe ukuthintana ngqo nesikhumba noma amehlo, okungadala i-frostbite noma okunye ukulimala.
Nakuba ukuqandisa i-nitrogen engamanzi kunikeza izinzuzo eziningi, kubalulekile ukuqaphela ukuthi kungase kungafaneleki kuzo zonke izinhlobo zokudla kwasolwandle, njengoba abanye bangase babhekane nezinguquko ekunambithekeni nasekuthungeni ngemva kokuqandisa. Ngaphezu kwalokho, kudingeka ukufudumeza okuphelele ngaphambi kokudla ukudla kwasolwandle okumanzi okuqandisiwe yi-nitrogen ukuqinisekisa ukuphepha kokudla.
