Vazhinji vanoziva mashandisirwo emvura nitrogen mumarabhoritari uye muzvipatara zvekuchengetedza sampuli.Nekudaro, kushandiswa kwayo muhupenyu hwezuva nezuva kuri kuwedzera, kusanganisira kushandiswa kwayo mukuchengetedza chikafu chegungwa chinodhura chekufambisa kureba.
Kuchengetedza chikafu chemugungwa kunouya nenzira dzakasiyana-siyana, sedziya dzinowanzoonekwa muzvitoro zvikuru, uko hove dzemugungwa dziri paaizi pasina kuomesa nechando.Zvisinei, nzira iyi inoguma nekuchengetedza nguva shoma uye haina kukodzera kutakurwa kure.
Kusiyana neizvi, chikafu chemugungwa chinotonhora chine nitrogen yemvura inzira inokurumidza uye inoshanda yekuomesa iyo inowedzera kutsva uye kukosha kwekudya kwegungwa.
Izvi zvinodaro nekuti tembiricha yenitrogen yakadzika zvakanyanya, inosvika pasi se -196 madhigirii Celsius, inobvumira kukurumidza kuomesa nechando, ichideredza kuumbwa kwemakristasi makuru echando panguva yechando, izvo zvinogona kukonzera kukuvara kusingakoshi kwesero.Inonyatso chengetedza kuravira uye kuumbwa kwezvokudya zvegungwa.
Maitiro ekushandisa nitrogen yemvura kuomesa chikafu chegungwa chakatwasuka.Kutanga, zvokudya zvegungwa zvitsva zvinosarudzwa, zvikamu zvisingadiwi uye tsvina zvinobviswa, uye zvakanyatsocheneswa.Zvadaro, hove yegungwa inoiswa muhomwe yepurasitiki yakavharwa, mhepo inodzingwa, uye bhegi rinomanikidzwa zvakanyanya sezvinobvira.Bhegi racho rinobva raiswa mumvura ine nitrogen tangi, kwainosara kusvika chikafu chegungwa chaoma chando uye chagadzirira kushandiswa gare gare.
Semuyenzaniso, Shengjie's seafood liquid nitrogen matangi ekuchengetera, anoshandiswa kunyanya kutonhora kwepamusoro-yekupedzisira kwegungwa, anozvirumbidza nekukurumidza kutonhora, nguva yekuchengetedza kwenguva refu, yakaderera michina yekudyara uye mutengo wekushandisa, zero simba rekushandisa, pasina ruzha, kushoma kugadzirisa, kuchengetedza ruvara rwekutanga rwegungwa, kuravira, uye zvinovaka muviri.
Nekuda kwekudziya kwakanyanya kwenitrogen yemvura, matanho akasimba ekuchengetedza anofanirwa kutorwa kana uchiibata kudzivirira kusangana neganda kana maziso, izvo zvinogona kukonzera chando kana kumwe kukuvara.
Kunyange zvazvo mvura yenitrogen yechando ichipa zvakawanda zvakanaka, zvakakosha kuziva kuti inogona kunge isina kukodzera kumarudzi ose ezvokudya zvegungwa, sezvo vamwe vanogona kuwana shanduko mukuravira uye magadzirirwo mushure mechando.Pamusoro pezvo, kudziya kwakaringana kunodiwa usati wadya mvura yenitrogen-yakaomeswa negungwa kuitira kuchengetedza chikafu.
