Umshini Wokupakisha Ikhofi Uqinisekisa Kanjani Ukusha Nokulondolozwa Kwephunga?"

Isingeniso:

Uma kukhulunywa ngezwe lekhofi, ubusha kanye nephunga elimnandi yizici ezimbili ezibalulekile ezingenza noma ziphule inkomishi kajoe. Inqubo eyinkimbinkimbi yokupakisha ikhofi idlala indima ebalulekile ekuqinisekiseni ukuthi lezi zimfanelo ziyalondolozwa kusukela ngesikhathi ubhontshisi uthoswa kuze kube yilapho ufika enkomishini yakho. Imishini yokupakisha ikhofi iguqule le nqubo, ivumela abakhiqizi ukuthi bagcine izinga elifiswayo lokusha kanye nephunga elimnandi kuyilapho benweba isikhathi seshelufu sekhofi. Kulesi sihloko, sizohlola ukuthi le mishini isebenza kanjani kanye namasu ahlukahlukene ewasebenzisayo ukuqinisekisa ukuthi ikhofi lakho lihlala lijabulisa izinzwa zakho.

Ukubaluleka Kokusha Nephunga:

Ngaphambi kokuhlolisisa ubunkimbinkimbi bemishini yokupakisha ikhofi, kubalulekile ukuqonda ukuthi kungani ukusha nokulondolozwa kwephunga kubaluleke kakhulu embonini yekhofi. Ukusha kubhekisela esikhathini lapho ubhontshisi bekhofi begcina khona ukunambitheka kwawo okuhlukile namaphunga. Kwaziwa kabanzi ukuthi ikhofi lisezingeni eliphezulu lokunambitheka kwalo emasontweni ambalwa ngemva kokuba ligazingiwe, ngemva kwalokho lilahlekelwa ukunyakazisa kwalo kanye nokusha. Ngakolunye uhlangothi, iphunga elimnandi liyisici esikhangayo nesihehayo esengeza kulokho okuhlangenwe nakho kokuzwa inkomishi yekhofi.

Iqhaza Lemishini Yokupakisha Ikhofi:

Imishini yokupakisha ikhofi, eyaziwa nangokuthi imishini yokupakisha ikhofi, iklanyelwe ukuvala ubhontshisi wekhofi noma ikhofi eligayiwe ezintweni zokupakisha ezingangeni moya, njengezikhwama noma amathini. Injongo eyinhloko iwukwenza umgoqo ovikela okungaphakathi ezintweni zangaphandle ezingonakalisa ikhwalithi yekhofi, okuhlanganisa ukuchayeka kumoya-mpilo, umswakama, ukukhanya, ngisho nokushintshashintsha kwezinga lokushisa. Le mishini isingatha yonke inqubo yokupakisha, kusukela ekugcwaliseni impahla yokupakisha ngekhofi kuya ekuyivaleni, iqinisekisa ukuthi umkhiqizo uhlala umusha futhi unephunga elimnandi uze ufinyelele kumthengi.

Amasu Wokuvala:

Ukuze kufezwe umsebenzi wokulondoloza ubusha nephunga, imishini yokupakisha ikhofi isebenzisa izindlela ezihlukahlukene zokuvala. Ake sihlole ezinye ezivame kakhulu:

Ukuvalwa kweVacuum:

Ukuvala i-vacuum kuyindlela esetshenziswa kakhulu ekufakweni kwekhofi. Le ndlela ihilela ukukhipha umoya entweni yokupakisha ngaphambi kokuba ivalwe, kwakhiwe indawo yokuhlanza ngaphakathi. Ngokuqeda umoya-mpilo, ukuvala i-vacuum kunciphisa kakhulu amathuba okukhipha i-oxidation, okungaba nomthelela omubi ekunambithekeni kwekhofi kanye nephunga elimnandi. Le nqubo isiza futhi ekuvimbeleni ukukhula kwesikhunta, amagciwane, noma okunye ukungcola okuchumayo lapho kukhona umoya-mpilo.

Ukuvalwa kwe-vacuum ngokuvamile kufinyelelwa ngenqubo yezinyathelo ezimbili. Okokuqala, ikhofi ifakwe ezintweni zokupakisha, futhi njengoba isikhwama sivaliwe, umoya owedlulele uyasuswa. Uma izinga lokungena elifiswayo selifinyelelwe, iphakheji livalwa ngokuqinile, okuqinisekisa ukuthi ikhofi lihlala lilisha isikhathi eside.

I-Modified Atmosphere Packaging (MAP):

I-Modified Atmosphere Packaging (MAP) enye indlela yokuvala edumile esetshenziswa imishini yokupakisha ikhofi. Esikhundleni sokudala i-vacuum, i-MAP ifaka ukufaka esikhundleni somoya ongaphakathi kwephakeji ngengxube ethize yegesi, ngokuvamile inhlanganisela ye-nitrogen, i-carbon dioxide, futhi ngezinye izikhathi amanani amancane omoya-mpilo. Ukwakheka kwengxube yegesi kungenziwa ngokwezifiso ukuze kuhambisane nezidingo ezithile zekhofi elipakishwayo.

Le nqubo isebenza ngokulawula ukwakheka kwegesi ngaphakathi kwephakheji ukuze kunwetshwe impilo yeshalofu yekhofi. I-nitrogen, igesi engasebenzi, ngokuvamile isetshenziselwa ukususa umoya-mpilo, ngaleyo ndlela ivimbele ukugeleza kwe-oxidation. Ngakolunye uhlangothi, i-carbon dioxide isiza ekulondolozeni iphunga ngokuvimbela ukulahleka kwezithako ezinuka kamnandi. Ngokukhohlisa umkhathi, i-MAP idala indawo evikelayo evikela ikhofi ekonakalisweni kuyilapho igcina ubusha nephunga lalo isikhathi eside.

Ukulondolozwa Kwephunga:

Ukugcina iphunga lekhofi kubalulekile njengokugcina ubusha balo. Imishini yokupakisha ikhofi ithuthukile ukuze ihlanganise namasu amaningi okuqinisekisa ukuthi iphunga elimnandi lekhofi lihlala linjalo phakathi nesikhathi salo seshelufu. Ake sihlole ezinye zalezi zindlela:

I-Oneway Degassing Valve:

Ama-valve endlela eyodwa yokukhipha umoya ayisici esidumile ekufakweni kwekhofi. Lawa ma-valve amancane ngokuvamile ahlanganiswa ezikhwameni zekhofi ukuze akhiphe isikhutha esidlulele esikhishwa ngokwemvelo ikhofi elisanda kugazingwa. I-carbon dioxide, ewumkhiqizo wenqubo yokugazinga, iyaqhubeka ikhishwa ubhontshisi wekhofi ngisho nalapho isigayiwe noma isiphelele. Uma le gesi ingakhululwa, ingaholela ekwakhiweni kwengcindezi ngaphakathi kwephakheji, okuthinta ikhwalithi yonke yekhofi.

I-valve yendlela eyodwa yokukhipha umoya ivumela i-carbon dioxide ukubaleka kuyilapho ivimbela umoya-mpilo ukuthi ungangeni kuphakheji. Le valve iklanywe ngolwelwesi oluvumela kuphela igesi ukuthi idlulele ohlangothini olulodwa, okuqinisekisa ukuthi ikhofi lihlala livikelekile ngaphandle kokuphazamisa ubusha nephunga lalo. Ngokugcina ibhalansi yegesi efanele, i-valve ivikela ngempumelelo ukunambitheka namaphunga ekhofi, inikeze umuzwa okhethekile wezinzwa kumthengi.

Ukupakishwa kwe-Foil evaliwe:

Enye indlela esetshenziselwa ukulondoloza iphunga ukupakishwa kwe-foil evaliwe. Le ndlela ihlanganisa ukubeka ikhofi endaweni yokupakisha equkethe izendlalelo eziningi, ngokuvamile okuhlanganisa ungqimba lwe-aluminium foil. Ucwecwe lusebenza njengesithiyo emoyeni, ukukhanya, nomswakama, konke okungaba nemiphumela elimazayo ephunga elimnandi lekhofi.

Indlela yokupakisha ye-foil evaliwe iqinisekisa ukuthi izinhlanganisela ezinuka kamnandi ezikhona ekhofini zivikelekile ezintweni zangaphandle. Ngokwenza isigxivizo esiqinile, okupakishwayo kuvimbela ukulahlekelwa amakha aguquguqukayo futhi kugcine iphunga elimnandi lekhofi kuze kube yilapho livulwa umthengi.

Isifinyezo:

Sengiphetha, imishini yokupakisha ikhofi idlala indima ebalulekile ekuqinisekiseni ukuthi ikhofi liyasha kanye nephunga elimnandi kuyo yonke impilo yalo yeshalofu. Ngokusebenzisa amasu afana nokuvala i-vacuum sealing kanye nokupakishwa kwe-atmosphere elungisiwe, le mishini yenza indawo evikelayo evikela ikhofi emoyeni, umswakama, nokukhanya. Ukwengeza, izici ezifana nama-valve asusa umoya ngendlela eyodwa kanye nokupakishwa kwe-foil evaliwe kunomthelela ekulondolozeni iphunga elimnandi, okuvumela ikhofi ukuthi ligcine iphunga lalo elihehayo kuze kube yilapho liphekwa. Ngosizo lwale mishini ethuthukisiwe nezindlela zokuvala, abathandi bekhofi bangazitika enkomishini kajoe enothe ngokunambitheka, iphunga elimnandi nokwaneliseka kwezinzwa. Ngakho-ke ngesikhathi esilandelayo lapho ujabulela ukuhlanganisa kwakho okuthandayo, khumbula inqubo eyinkimbinkimbi nokuzinikela okungena ekulondolozeni ingqikithi yekhofi lakho.
