Umshini wokuqandisa owuketshezi we-nitrogen owuketshezi wohlobo lomhubhe usebenzisa umzimba oshiselwe ngokugcwele, wensimbi engagqwali, ohlangabezana nenguqulo entsha ye-European EHEDG kanye namazinga e-USDA aseMelika.Umshini wokuqanda ngokushesha we-nitrogen owuketshezi owuhlobo lwe-tunnel ulungele noma yikuphi ukudla okudinga ukupholiswa, ukuqandiswa ngokushesha noma ukuqweqwediswa/ukuqina kanye neqhwa emgqeni wokuhlanganisa noma ukukhiqizwa okuqhubekayo.Umshini wokuqandisa ngokushesha wohlobo lomhubhe ungaqinisekisa ikhwalithi yokudla.
Umshini wokuqandisa uketshezi we-tunnel liquid nitrogen usetshenziselwa ikakhulukazi ukuqandisa ukudla okusheshayo.Indlela yokulawula yesikrini sokuthinta + i-PLC yamukelwa ukuqapha ukushintsha kwezinga lokushisa ebhokisini ngesikhathi sangempela.Ngemva kokuba amapharamitha asethiwe, okokusebenza kungasebenza ngokuzenzakalelayo.Ukusebenza kulula, ukwethembeka kunamandla, futhi ukusebenza kugcina nge-alamu ezenzakalelayo.
Umshini wokuqanda ngokushesha we-nitrogen owuketshezi usebenzisa i-nitrogen ewuketshezi njengendawo yokupholisa ukuze umise ukudla ngokushesha futhi ngamandla.Ngenxa yokuthi ukuqandisa okusheshayo kushesha kakhulu, ngeke kulimaze isakhiwo sangaphakathi sezicubu zokudla, ngaleyo ndlela kuqinisekiswe ubuqiniso, ijusi yangempela, umbala wangempela kanye nokudla okunomsoco wokudla Kunezici ezinhle kakhulu zamakhemikhali, futhi ukusetshenziswa kokumisa kuncane kakhulu, futhi ingabona ukuqandisa okusheshayo kwama-monomers ngaphandle kokulahlekelwa ukunamathela.
Izinzuzo ze-tunnel liquid nitrogen esheshayo efrijini:
① Yiqhwa emizuzwini emi-5, izinga lokupholisa ngu-≥50℃/min, isivinini sokuqandisa siyashesha (isivinini sokuqandisa sicishe sibe izikhathi ezingama-30-40 kunendlela evamile yokuqandisa), kanye nokuqandisa okusheshayo nge-nitrogen ewuketshezi kungenza ukudla. ngokushesha dlula endaweni enkulu yokukhula kwekristalu yeqhwa engu-0℃～5℃.
②Ukugcina ikhwalithi yokudla: ngenxa yesikhathi esifushane sokuqanda se-nitrogen ewuketshezi kanye nezinga lokushisa eliphansi elingu -196°C, ukudla okuqandiswe i-nitrogen ewuketshezi kungagcina umbala, iphunga, ukunambitheka kanye nenani lokudla okunempilo ngaphambi kokucutshungulwa ngezinga elikhulu kakhulu.Ukunambitheka kokudla kungcono kunendlela yendabuko yokuqandisa ngokushesha.
③ Ukusetshenziswa okuncane okomile kwezinto zokwakha: Imvamisa, izinga lokulahlekelwa ukusetshenziswa okomile kokuqandisa lingama-3-6%, kuyilapho ukubanda okusheshayo nge-nitrogen ewuketshezi kunganciphisa ku-0.25-0.5%.
Izindleko zemishini namandla ziphansi, ukutshalwa kwempahla ngesikhathi esisodwa kuncane, izindleko zokusebenza ziphansi, kulula ukubona imishini kanye nolayini wokuhlanganisa othomathikhi, nokuthuthukisa ukukhiqiza.
④Ukusebenza kulula, futhi ukuhlinzwa okungenamuntu kuyenzeka;izindleko zokunakekela ziphansi, futhi cishe azikho izindleko zokuyilungisa.
⑤Indawo ephansi incane kakhulu futhi akukho msindo.
Izinzuzo zomshini wokuqandisa we-nitrogen owuketshezi wohlobo lwe-tunnel yilezi: unyawo oluncane, ukulungiswa okuguquguqukayo kokuphumayo, ukusebenza okulula, ukuhlanza nokugcinwa okulula, akukho ukungcoliswa nomsindo, ukonga kanye nemvelo.Isikhathi sokuqandisa sifushane, umphumela muhle, futhi umphumela omuhle kakhulu wokuqandisa ufinyelelwa ngokusetshenziswa okuncane kwamandla.Isetshenziswa kakhulu ekudleni okuqandisiwe okuhlukahlukene okufana nenyama, ukudla kwasolwandle kanye nemikhiqizo yasemanzini, i-shabu-shabu, izithelo, imifino kanye ne-pasta.Okufana nalokhu: ukudla kwasolwandle, i-abalone, izimfanzi zasolwandle, ikhukhamba lasolwandle, amalobster, inhlanzi yasolwandle, isalmon, inkalankala, inyama, amabhola erayisi asuthayo, amadombolo, amabhanisi, amadombolo elayisi, ama-spring roll, ama-wonton, imikhiqizo kashizi, amahlumela e-bamboo, ummbila onamathelayo, i-velvet i-antler, ama-strawberries, uphayinaphu, i-bayberry ebomvu, i-papaya , i-litchi, ukudla okulungiselelwe, njll.
