Initrogen yolwelo: Irhasi yeNitrojeni ekwimo yolwelo.I-inert, ayinambala, ayinavumba, ayinamhlwa, ayinakutsha, ubushushu obugqithisileyo be-cryogenic.I-nitrogen yenza uninzi lwe-atmosfera (i-78.03% ngevolumu kunye ne-75.5% ngobunzima).I-nitrogen ayisebenzi kwaye ayikuxhasi ukutsha.I-Frostbite ebangelwa kukudibana okugqithisileyo kwe-endothermic ngexesha lokukhupha umphunga.
Initrogen elulwelo ngumthombo ofanelekileyo wokubanda.Ngenxa yeepropathi zayo ezizodwa, initrogen engamanzi iye ngokuthe ngcembe ihlawulwe ingqalelo ngakumbi nangakumbi kwaye yamkelwa ngabantu.Sele isetyenziswa kakhulu ekufuyweni kwezilwanyana, kwishishini lezonyango, kwishishini lokutya, nakwimimandla yophando lwe-cryogenic.Kwi-electronics, i-metallurgy, i-aerospace, ukuveliswa koomatshini kunye neminye imiba yesicelo iye yanda kwaye iphuhlisa.
Ukusetyenziswa kwenitrogen elulwelo ekutyeni okukhenkceza ngokukhawuleza
I-nitrogen yolwelo ekhenkcezisiweyo njengenye yeendlela zokuqokelelwa komkhenkce ifunyenwe lishishini lokulungisa ukutya, kuba inokuqonda iqondo lobushushu elisezantsi le-cryogenic super ekhenkcezisiweyo ekhawulezayo, kodwa kunye nokuqonda inxalenye yotshintsho lweglasi lokutya okunomkhenkce, ukwenza ukutya okunyibilikayo ukubuyela kwimo yayo yantlandlolo engaqhelekanga kunye nemeko yesondlo sokuqala, inkqubela eqatha kakhulu umlinganiswa ukutya emkhenkceni, Ngoko ke, ibonisa ubungqabavu ezizodwa kushishino olukhawulezayo umkhenkce.Xa kuthelekiswa nezinye iindlela zokukhenkceza, ukukhenkceza ngokukhawuleza kwenitrogen enolwelo kunezi nzuzo zilandelayo:
1 abasebenzi benze imifuniselo eluncedo kulo mba.
(2) Ukudibanisa isimilo sokutya: ngenxa yexesha elifutshane lokukhenkceza lenitrogen engamanzi, ukutya okukhenkceziswe yinitrogen engamanzi kunokunxulunyaniswa nombala, ivumba, incasa kunye neendleko zesondlo phambi kokuba kusetyenzwe ngowona mgangatho uphezulu.Iziphumo zabonisa ukuba i-areca catechu enyangwe ngenitrogen engamanzi yayinomthamo we-chlorophyll ephezulu kunye nomtsalane olungileyo.
(3) ukusetyenziswa okuncinci okomileyo kwemathiriyeli: ngokuqhelekileyo ilahleko eyomileyo enomkhenkce yi-3 ~ 6%, kunye nokukhenkceza kwenitrogen engamanzi kunokupheliswa ukuya kwi-0.25 ~ 0.5%.
(4) Cwangcisa ukuthunyelwa kwezixhobo kunye nokusetyenziswa kwamandla kuphantsi, kulula ukuqonda umatshini kunye nomgca wokuhlanganisa osebenzayo, ukuphucula imveliso.
Okwangoku, kukho iindlela ezintathu zokukhenkceza ngokukhawuleza kwenitrogen engamanzi, ezizezi, ukukhenkceza okutshizwayo, ukukhenkceza kwediphu kunye nomoya obandayo wokukhenkceza, phakathi kwawo ukukhenkceza okutshizwayo kusetyenziswa kakhulu.
Ukusetyenziswa kwenitrogen engamanzi ekusetyenzweni kwesiselo
Ngoku, abaninzi abavelisi beziselo baye bamkela i-nitrogen okanye i-nitrogen kunye ne-C02 mix-up endaweni ye-C02 yendabuko, ukubamba iziselo zokupakisha ze-inflatable.Iziselo ezinekhabhoni ephezulu ezizaliswe yinitrogen zibangele iingxaki ezimbalwa kunezo zizaliswe yicarbon dioxide yodwa.I-nitrojeni iyanqweneleka kwiziselo ezisezinkonkxweni ezifana newayini kunye nejusi yeziqhamo.Inzuzo yokuzalisa iinkonkxa zesiselo ezingavuthekiyo ngenitrogen engamanzi kukuba inani elincinci lenitrogen engamanzi etofweyo lisusa ioksijini ukusuka kwindawo ephezulu yetoti nganye kwaye linike i-inert yegesi kwindawo ephezulu yetanki yokugcina, ngaloo ndlela yandisa ubomi bokugcina. nezinokonakala.
Ukusetyenziswa kwenitrogen elulwelo ekugcinweni nasekugcinweni kweziqhamo nemifuno
Ukugcinwa kwenitrogen yolwelo kwiziqhamo kunye nemifuno kunenzuzo yokulawula umoya, kunokulungelelanisa imveliso yezolimo ngexesha eliphakamileyo lonyaka kunye nonikezelo lwexesha elingekhoyo kunye nokuchasana kwemfuno, kuphelise ilahleko yokugcina.Isiphumo somoya womoya kukuphucula ukuxinana kwenitrogen, ukulawula umlinganiselo wenitrogen, ioksijini kunye negesi yeC02, kwaye yenze idityaniswe kwisimo esizinzileyo, iziqhamo eziphantsi kunye nemifuno ephefumla ngamandla, ukulibazisa ikhosi emva kokuvuthwa, ukuze iziqhamo kunye nemifuno edityaniswe nemeko engaqhelekanga yokukha kunye neendleko zesondlo sokuqala, zandise ukutsha kweziqhamo kunye nemifuno.
Ukufakwa kwenitrogen elulwelo ekusetyenzweni kwenyama
Ulwelo lwenitrogen lungasetyenziselwa ukuphucula ubuninzi beemveliso kwinkqubo yokuqhola, ukunqunqa okanye ukuxuba inyama.Ngokomzekelo, ekuqhutyweni kwe-salami-type sausage, ukusetyenziswa kwe-nitrogen engamanzi kunokuphucula ukugcinwa kwamanzi kwenyama, ukuthintela i-oxidation yamafutha, ukuphucula ukusika kunye nomgangatho ophezulu.Isetyenziselwa ukucutshungulwa kwenyama ehlaziyiweyo efana nezimuncumuncu zenyama kunye nenyama egciniweyo, ayinakukhawulezisa ukunyibilika kweqanda elimhlophe kwaye yomeleze ukugcinwa kwamanzi xa inyama ibhidekile, kodwa ikwaluncedo kakhulu ekudibaniseni imilo eyodwa yemveliso.Enye inyama impahla ngulwelo nitrogen ukupholisa ngokukhawuleza, hayi kuphela uxhulumaniso esisigxina phakathi kweempawu eshushu inyama, igesi kunye nokuqinisekisa impilo inyama noxolo.Kwitekhnoloji yokucubungula, akukho mfuneko yakukhathazeka malunga nefuthe lokunyuka kwamaqondo obushushu kumgangatho wenyama, kwaye ukulungiswa akuchatshazelwa ngubushushu bezinto eziphathekayo, ixesha lokucubungula, iimeko zonyaka, kodwa kunokwenza inkqubo yokucubungula kwi-oksijini ephantsi yoxinzelelo oluyinxenye, kuluhlu oluthile ukwandisa ubomi beshelufu yeemveliso.
Ukusetyenziswa kwenitrogen engamanzi ekutyeni kokutya kubushushu becryogenic
Ukutyunyuzwa kweqondo lokushisa kwe-Cryogenic yinkqubo yokuqhekeka ibe ngumgubo phantsi kwesenzo samandla angaphandle, epholileyo kwiqondo lokushisa le-embrittlement point.Ukutyunyuzwa kobushushu beCryogenic kokutya sikhono esitsha sokwenza ukutya esikhule kwiminyaka yakutshanje.Obu buchule bufanelekile ukucubungula ukutya kunye nezinto ezininzi ezinevumba elimnandi, isiqulatho samafutha aphezulu, iswekile eninzi kunye nezinto ezininzi zegelatin.Ubushushu beCryogenic ukutyunyuzwa ngesohlwayo sokulahlwa kwenitrogen elulwelo, unako nokuba nezinto zethambo, ulusu, inyama, iqokobhe kunye nezinye zonke ixesha lokutyumza, ukuze izinto ezigqityiweyo zincinci kwaye zidibene nesondlo sayo esiluncedo.Ukuba iJapan iya kuba ngumkhenkce ngolwelo lwenitrogen yolwandle, i-chitin, imifuno, iziqholo, njl.njl kwi-grinder yokusila, inokwenza imveliso egqityiweyo ilingane ne-100μm engezantsi, kunye nekhonkco elisisiseko kwindleko yesondlo sokuqala.Ukongeza, ubushushu be-cryogenic butyunyuzwa ngenitrogen engamanzi bunokutyumza izinto ekunzima ukuzityumza kwiqondo lobushushu begumbi, izinto ezibuthathaka kubushushu kwaye kulula ukuwohloka xa zishushu kwaye kulula ukuzihlalutya.Ukongeza, initrogen engamanzi ingasetyenziselwa ukutyumza inyama enamafutha, imifuno efumileyo kunye nokunye ukutya ekunzima ukutyunyuzwa kubushushu begumbi, kwaye kusenokusetyenziswa ukwenza ukutya okutsha okucutshungulwayo.
Ukusetyenziswa kwenitrogen elulwelo kwipakethe yokutya
Inkampani yaseLondon iphuhlise indlela elula nesebenzayo yokugcina ukutya kusitsha ngokudibanisa amathontsi ambalwa enitrogen engamanzi kwipakethe.Xa i-nitrogen engamanzi ingumphunga ibe yigesi, umthamo wayo ukhula ngokukhawuleza, ngokukhawuleza utshintshe uninzi lwerhasi yokuqala kwingxowa yokupakisha, ukuphelisa ukonakaliswa kokutya okubangelwa yi-oxidation, ngaloo ndlela kwandiswa kakhulu ukutsha kokutya.
Ukufakwa kwenitrogen elulwelo ekuthuthweni kokutya efrijini
Ukuthutha okufakwe efrijini yinxalenye ebalulekileyo yoshishino lokutya.Ukuphuhlisa izakhono zolwelo lwenitrogen yokukhenkcisa, ukukhulisa oololiwe abafakwe efrijini benitrogen, iimoto ezifakwe efrijini kunye nezikhongozeli ezifakwe efrijini yindlela yokukhula eqhelekileyo ngoku.Ukusetyenziswa kwenkqubo yokukhenkceza ulwelo lwenitrogen kumazwe aphuhlileyo iminyaka emininzi lubonisa ukuba ulwelo nitrogen isikhenkcezisi inkqubo isakhono ukugcinwa efrijini leyo enokukhuphisana inkqubo umatshini efrijini kurhwebo kwaye kwakhona utyekelo ukukhula ukutya efrijini zothutho.
Ezinye izicelo zenitrogen elulwelo kushishino lokutya
Enkosi kwisenzo sokukhenkceza senitrogen engamanzi, ijusi yeqanda, i-condiments engamanzi, kunye nesosi yesoya inokucutshungulwa ngokulinganayo ukuba ihambe ngokukhululekileyo kwaye igalele ukutya okukhenkcezisiweyo okufumaneka lula kwaye kulungiswe lula.Xa kusila iziqholo kunye nezongezelelo zokutya ezifunxa amanzi, ezifana neswekile endaweni yeswekile kunye nelecithin, initrogen engamanzi igalelwa kwigrinder ukuhlawula iindleko kunye nokunyusa isivuno sokusila.Iziphumo zibonisa ukuba ukuqhawuka kodonga lwe-pollen ngokucinywa kwenitrogen emanzi kudityaniswe nobushushu obuphezulu bokunyibilika kuneempawu zeziqhamo ezilungileyo, izinga eliphezulu lokuqhawuka kodonga, isantya esikhawulezayo, ukusebenza ngokuzinzileyo kwe-pollen kunye nokukhululeka kungcoliseko.
