Tanki yoziziritsa chakudya m'nyanja

Mwachidule:

Seafood liquid nitrogen cryopreservation ukadaulo ndiukadaulo watsopano woziziritsa chakudya m'zaka zaposachedwa. Kutentha kokhazikika kwa nayitrogeni wamadzimadzi ndi -195.8 ℃, ndipo pakali pano amadziwika kuti ndi njira yabwino kwambiri yoziziritsira zachilengedwe, yothandiza komanso yotsika mtengo kwambiri. Pamene nayitrogeni wamadzimadzi akhudzana ndi nsomba, Kutentha kwa kutentha kumapitirira 200 ℃, ndipo chakudyacho chikhoza kuzizira mofulumira mkati mwa mphindi 5. Kuzizira kofulumira kumapangitsa kuti makristasi a ayezi akhale ochepa kwambiri, amalepheretsa kutayika kwa madzi, amalepheretsa kuwonongedwa kwa mabakiteriya ndi tizilombo toyambitsa matenda, amachititsa kuti chakudya chisawonongeke, chimapangitsa kuti chakudya chisawonongeke, chimapangitsa kuti chakudya chikhale chosavuta komanso chosavuta. kukoma ndi zakudya za m'nyanja, kotero kuzizira kwa nthawi yaitali kungathenso kuonetsetsa kukoma kwabwino.

Mufiriji wa nayitrogeni wamadzi am'nyanja ndiwo woyamba kugwiritsidwa ntchito pozizira kwambiri zam'madzi chifukwa amazizira mwachangu, nthawi yayitali yosungira, mtengo wotsika wa zida, mtengo wotsika, osagwiritsa ntchito mphamvu, phokoso komanso kukonza. Iwo akhoza ananeneratu kuti madzi asafe cryogenic firiji luso pang'onopang'ono m'malo chikhalidwe makina firiji ndi regrigeration luso, amene adzabweretsa kusintha kwambiri ntchito mufiriji chikhalidwe.

Zogulitsa:

○ Ukadaulo wapamwamba wa vacuum wosanjikiza zambiri umagwiritsidwa ntchito pofuna kuonetsetsa kuti madzi amadzimadzi a nayitrojeni atayaka kwambiri (<0.8%) komanso mtengo wotsika kwambiri.

○ Kalondolondo wanzeru ndi kasamalidwe ka thanki ya nayitrogeni yamadzimadzi imatha kuyang'anira kutentha ndi kuchuluka kwa madzi a thanki yazakudya zam'madzi mu nthawi yeniyeni, kuzindikira kudzaza kokha, alamu yazovuta zosiyanasiyana, ndikuwonetsetsa kuti zida zikuyenda bwino. Panthawi imodzimodziyo, imapereka kayendetsedwe ka kayendetsedwe ka katundu, zomwe zimapangitsa kuti kasamalidwe ka katundu atuluke m'nyumba yosungiramo katundu komanso m'nyumba yosungiramo katundu momveka bwino.

○ Zigoba zamkati ndi zakunja zimapangidwa ndi chitsulo chosapanga dzimbiri cha chakudya kuti zitsimikizire moyo wa malondawo kwa zaka zopitilira 10.

○Mapangidwe a thireyi ozungulira apangidwa kuti azithandizira kupezeka kwazakudya zam'nyanja. Mitundu ina imatha kukhala ndi mawonekedwe ozungulira amagetsi kuti azindikire zodziwikiratu.

○ Itha kusungidwa mu gasi ndi madzi kuonetsetsa kuti kutentha kwa pakamwa pa thanki kufika -190 digiri C.

Ubwino wazinthu:

○Kuchepa kwa ma evaporation a nayitrogeni wamadzimadzi
Ukadaulo wapamwamba wa vacuum multilayer insulation umatsimikizira kutayika kwamadzi otsika kwa nayitrogeni wamadzimadzi komanso kutsika mtengo kwa ntchito.

○ Zaukadaulo zatsopano zimasunga kukoma koyambirira
Zamadzimadzi nayitrogeni mofulumira kuzizira, chakudya ayezi galasi particles osachepera, kuthetsa imfa ya madzi, ziletsa mabakiteriya ndi tizilombo zina kuwonongeka kwa chakudya, kuti chakudya pafupifupi palibe makutidwe ndi okosijeni kusinthika ndi rancidity yekha.

○ Dongosolo lanzeru lowunikira
Itha kukhala ndi njira yowunikira mwanzeru, kuyang'anira nthawi yeniyeni ya kutentha kwa thanki iliyonse, kutalika kwa msinkhu wamadzimadzi, ndi zina zotero, imatha kuzindikiranso kudzaza kokha, mitundu yonse ya ma alarm.
