Ithangi lokuqandisa ukudla kwasolwandle

Uhlolojikelele:

Ubuchwepheshe be-seafood liquid nitrogen cryopreservation ubuchwepheshe obusha bokuqandisa ukudla eminyakeni yamuva.Izinga lokushisa elijwayelekile le-nitrogen eyi-liquid lingu-195.8 ℃, futhi njengamanje liqashelwa njengendlela yokupholisa enobungani kakhulu nemvelo, ephumelelayo neyonga kakhulu.Uma i-nitrogen ewuketshezi ithintana nezilwane zasolwandle, Umehluko wokushisa ungaphezu kuka-200 ℃, futhi ukudla kungase kumiswe iqhwa ngokushesha phakathi nemizuzu engu-5. Inqubo yokuqandisa esheshayo yenza izingxenye zamakristalu eqhwa zezinhlanzi zasolwandle zibe zincane kakhulu, zivimbele ukulahleka kwamanzi, zivimbele ukubhujiswa. amabhaktheriya nezinye izinambuzane ezincane, kwenza ukudla kucishe kungabi nambala oxidative kanye namafutha, futhi igcine umbala wokuqala, ukunambitheka kanye nezakhi zokudla kwasolwandle, ngakho ukuqandisa okuhlala isikhathi eside kungaqinisekisa futhi ukunambitheka okungcono kakhulu.

Ifriji ye-nitrogen ye-seafood liquid ingeyokuqala esetshenziswa ekubazeni ukudla kwasolwandle kwezinga eliphezulu ngenxa yesiqandisi saso esisheshayo, isikhathi eside sokulondoloza, izindleko zokufakwa kwemishini ephansi, izindleko eziphansi zokusebenza, ukusetshenziswa kwamandla, akukho msindo futhi akukho kunakekelwa.Kungabikezelwa ukuthi ubuchwepheshe besiqandisi be-nitrogen cryogenic kancane kancane buzothatha indawo yobuchwepheshe befriji obusetshenziswa yimishini kanye nokufakwa kabusha, okuzoletha izinguquko ezinqala ekusebenzeni kwesiqandisi esivamile.

Izici Zomkhiqizo:

○ Ubuchwepheshe bokufakelwa kwe-vacuum ephezulu kwezendlalelo eziningi kwamukelwa ukuze kuqinisekiswe izinga lokulahlekelwa eliphansi kakhulu lokuhwamuka kwe-nitrogen ewuketshezi(<0.8%) kanye nezindleko zokusebenza eziphansi kakhulu.

○ Uhlelo lokuqapha nokuphatha oluhlakaniphile lwethangi le-nitrogen eliwuketshezi lingaqapha izinga lokushisa kanye nezinga loketshezi lwethangi lezilwane zasolwandle ngesikhathi sangempela, libone ukugcwaliswa okuzenzakalelayo, i-alamu yamaphutha ahlukahlukene angenzeka, futhi iqinisekise ukusebenza okuphephile kwezisetshenziswa.Ngesikhathi esifanayo, ihlinzeka ngohlelo lokuphathwa kwempahla yokugcina impahla, okwenza ukuphathwa kwezimpahla kuphume endaweni yokugcina izinto futhi kucace lapho uthi nhlá.

○ Amagobolondo angaphakathi nangaphandle enziwe ngensimbi engagqwali yezinga lokudla ukuze kuqinisekiswe impilo yomkhiqizo ngaphezu kweminyaka eyi-10.

○Isakhiwo sethreyi esijikelezayo sangaphakathi siklanyelwe ukusiza ukufinyelela kokudla kwasolwandle.Amanye amamodeli angafakwa ngesakhiwo esijikelezayo sikagesi ukuze abone ukufinyelela okuzenzakalelayo.

○ Ingagcinwa kukho kokubili igesi noketshezi ukuze kuqinisekiswe ukuthi izinga lokushisa lomlomo wethangi lifinyelela ku- -190 degree C.

Izinzuzo zomkhiqizo:

○Izinga lokuhwamuka eliphansi le-nitrogen ewuketshezi
Ubuchwepheshe bokufaka i-vacuum multilayer ephezulu buqinisekisa izinga eliphansi lokulahlekelwa kokuhwamuka kwe-nitrogen enguketshezi kanye nezindleko eziphansi zokusebenza.

○ Ubuchwepheshe obusha bugcina ukunambitheka kwangempela
Liquid nitrogen okokuqandisa ngokushesha, ukudla ice crystal izinhlayiya ubuncane, aqede ukulahlekelwa amanzi, avimbele amagciwane kanye nezinye amagciwane umonakalo ukudla, ukuze ukudla cishe akukho ukushintsha kwe-oxidation kanye rancidity kuphela.

○ Isistimu yokuqapha ehlakaniphile
Ingahlonyiswa ngesistimu yokuqapha ehlakaniphile, ukuqapha kwenethiwekhi ngesikhathi sangempela sokushisa kwethangi ngalinye, ukuphakama kwezinga le-liquid, njll., kungabuye kubone ukugcwaliswa okuzenzakalelayo, zonke izinhlobo ze-alamu yephutha. ngaphandle kokuphathwa kwesitoreji.
