Yiziphi Izindlela Zokupakisha Ezitholakalayo Zemishini Yokupakisha Isaladi?

Isingeniso

Imishini yokupakisha idlala indima ebalulekile ekupakisheni imikhiqizo ngendlela ephumelelayo nehlanzekile, ikakhulukazi embonini yokudla. Uma kukhulunywa ngokupakisha isaladi, kunezinketho ezahlukene ezitholakalayo ezihlangabezana nezidingo ezahlukene zokupakisha. Le mishini yokupakisha iklanyelwe ukupakisha amasaladi ngendlela eqinisekisa ukuthi ahlanzekile, yandise isikhathi sokuphila, futhi ithuthukise ukwethulwa komkhiqizo. Kulesi sihloko, sizohlola izinketho ezahlukene zokupakisha ezitholakalayo zemishini yokupakisha isaladi, sigqamisa izici zayo, izinzuzo, kanye nokufaneleka kwezinhlobo ezahlukene zemikhiqizo yesaladi.

Ukuqonda Ukubaluleka Kokupakisha Amasaladi

Ngaphambi kokuhlola izinketho ezithile zokupakisha, kubalulekile ukuqonda ukubaluleka kokupakisha ngokwesimo semikhiqizo yesaladi. Amasaladi ayizinto ezibolayo ezidinga ukupakisha ngokucophelela ukuze zigcine zintsha futhi zisezingeni eliphezulu. Ukupakisha okufanele akuvikeli nje kuphela amasaladi ekungcoleni nasekulimaleni kodwa futhi kuqinisekisa ukuthi ahlala ekhanga abathengi. Ngaphezu kwalokho, izixazululo zokupakisha ezisebenzayo zingandisa isikhathi sokuphila kwamasaladi, zinciphise ukulahlwa kokudla futhi zinciphise izindleko kokubili kubakhiqizi nakubathengi. Ake sihlole izinketho ezahlukene zokupakisha ezitholakalayo zemishini yokupakisha isaladi.

Ukupakisha i-Vacuum

Ukupakisha nge-vacuum kuyindlela esetshenziswa kabanzi yokupakisha amasaladi. Le nqubo ihilela ukukhipha umoya ephaketheni ngaphambi kokulivala, ukudala indawo ye-vacuum. Le ndlela inikeza izinzuzo eziningana zokupakisha isaladi. Okokuqala, ukupakisha nge-vacuum kuvimbela ukukhula kwamagciwane abangela ukonakala kanye nezikhunta ngokunciphisa amazinga omoya-mpilo, ngaleyo ndlela kuthuthukisa isikhathi sokuphila kwesaladi. Okwesibili, ukungabikho komoya kuvimbela i-oxidation, kugcina umbala kanye nokuthungwa kwesaladi. Ukupakisha nge-vacuum kunikeza nokuvala okungenamoya okuvimbela ukulahleka komswakama, okugcina isaladi isha futhi iqinile.

Imishini yokufaka i-vacuum itholakala ngobukhulu obuhlukahlukene kanye nokucushwa, inikeza ukuguquguquka okusekelwe ezidingweni zokukhiqiza kanye nokupakisha. Le mishini ingaphatha izinhlobo ezahlukene zezinto zokupakisha isaladi, kufaka phakathi amafilimu nezikhwama. Ukupakisha i-vacuum kufaneleka kakhulu kuma-greens aluhlaza, njengoba kuvimbela ukubuna futhi kulondoloza ubusha bawo obuhlukile. Ngaphezu kwalokho, isimo esincane nesingenamoya samaphakheji avaliwe nge-vacuum senza kube kuhle kakhulu ukuthuthwa nokugcinwa, ukuvimbela umonakalo ngesikhathi sokuthutha.

Ukupakishwa Kwesimo Sezulu Okuguquliwe (IMAP)

I-Modified Atmosphere Packaging, evame ukubizwa ngokuthi i-MAP, ingenye indlela ethandwayo yokupakisha isaladi. Le ndlela ihilela ukushintsha ukwakheka komoya ngaphakathi kwephakheji ukuze kudalwe isimo esihle kakhulu sokulondolozwa komkhiqizo. Ngokulungisa amazinga e-oxygen, i-carbon dioxide, ne-nitrogen, i-MAP yandisa isikhathi sokuphila kwamasaladi futhi igcina ikhwalithi yawo.

Imishini yokufaka i-MAP ifakwe amandla okususa igesi athatha indawo yomoya ozungezile ngengxube yegesi elawulwayo. Le ndlela inciphisa ukukhula kwamagciwane, ivimbele ngempumelelo ukonakala futhi yandise ubusha besaladi. Isimo esishintshiwe sisiza futhi ukugcina umbala wemvelo wesaladi, ukuthungwa, kanye nephunga, okuthuthukisa ukukhanga kwayo iyonke. Ngaphezu kwalokho, ukufakwa kwe-MAP kunikeza inzuzo yokunciphisa isidingo sezilondolozi kanye nezithasiselo, okwenza kube inketho ekhangayo kubathengi abaqaphela impilo.

Izindlela Zokuvala: Ukuvala Ukushisa Nokuvala Okubandayo

Uma kukhulunywa ngokuvala iphakheji yamasaladi, kunezindlela ezimbili eziyinhloko: ukuvala ukushisa kanye nokuvala okubandayo. Zombili lezi zindlela zinikeza izindlela ezisebenzayo zokuqinisekisa ubuqotho bomkhiqizo kanye nokusha.

Ukuvala ukushisa kuyindlela esetshenziswa kabanzi ehilela ukufaka ukushisa ezintweni zokupakisha ukuze kudalwe uphawu oluqinile. Le ndlela isebenza ngokuncibilikisa ungqimba olulodwa lwezinto zokupakisha, olube selunamathela kolunye ungqimba, lwakha uphawu oluqinile. Ukuvala ukushisa kuvame ukusetshenziswa kumasaladi okupakisha kumafilimu nezikhwama eziguquguqukayo. Ukushisa kungasetshenziswa kusetshenziswa izinhlobo ezahlukene zemishini, njengezinto zokuvala ukushisa eziqhubekayo noma izinto zokuvala umoya, kuye ngomthamo wokukhiqiza kanye nezidingo zokupakisha.

Ngakolunye uhlangothi, ukuvala okubandayo kusebenzisa izinamathiseli ezithinta ukucindezela ukudala isibopho phakathi kwezingqimba zokupakisha. Ukuvala okubandayo kuvame ukuthandwa ezintweni zokupakisha ezingakwazi ukumelana nokushisa, njengezinhlobo ezithile zamafilimu asekelwe ezitshalweni noma ukupakisha okunomanyolo. Le ndlela yokuvala inikeza ikhambi elinobungani nemvelo njengoba lingadingi amandla okushisa, okwenza kube lula ukusebenzisa amandla futhi kunciphisa umthelela wekhabhoni wenqubo yokupakisha.

Izixazululo Zokupakisha Ezinobungani Nemvelo

Njengoba kukhula ukukhathazeka ngemvelo kanye nesidingo sokupakisha okusimeme, imboni yokupakisha isaladi ibone nokuvela kwezinketho ezinobungani nemvelo. Lezi zixazululo zokupakisha zigxile ekunciphiseni imfucuza, ukusebenzisa izinto ezingasetshenziswa kabusha, kanye nokunciphisa umthelela wemvelo.

Enye indlela enjalo ukupakishwa okunomanyolo, okuklanyelwe ukuhlukana kube yizinto zemvelo lapho kufakwa izimo zomanyolo. Lezi zinto zivame ukwenziwa ngezinsiza ezivuselelekayo njengefilimu ezisekelwe ezitshalweni noma amapulasitiki abolayo. Ukupakishwa okunomanyolo kunikeza okunye okusimeme kakhulu kunepulasitiki yendabuko, okunikeza umthelela ophansi emvelweni kanye nokukhiqizwa kwemfucuza.

Esinye isisombululo sokupakisha esinobungani nemvelo ukupakisha okungasetshenziswa kabusha. Ngokusebenzisa izinto ezingaphinde zisetshenziswe kalula, njengezinhlobo ezithile zepulasitiki noma ibhodi lephepha, abakhiqizi bangafaka isandla emnothweni ojikelezayo. Ukuphinda kusetshenziswe kabusha kusiza ukonga izinsiza, ukunciphisa ukusetshenziswa kwamandla, kanye nokunciphisa imfucuza yokulahla udoti.

Isifinyezo

Ekuphetheni, kunezindlela ezahlukahlukene zokupakisha ezitholakalayo zemishini yokupakisha isaladi, ezihlangabezana nezidingo ezahlukene mayelana nokulondolozwa komkhiqizo, ukwethulwa kwawo, kanye nokusimama. Ukupakisha nge-vacuum kunikeza isikhathi eside sokulinda, ukusha okuthuthukisiwe, kanye namakhono okuthutha amahle kakhulu. Ukupakisha Nge-Modified Atmosphere (MAP) kunikeza izimo ezilawulwayo ezivimbela ukonakala, zigcine ikhwalithi, futhi zinciphise isidingo sezilondolozi. Izindlela zokuvala ukushisa kanye nokuvala okubandayo ziqinisekisa ukupakisha okuphephile, kanye nokuguquguquka kokwamukela izinto ezahlukene kanye nokucatshangelwa kwemvelo. Okokugcina, izixazululo zokupakisha ezinobungani nemvelo zinegalelo emizamweni yokusimama, zinikeza izinketho ezingasetshenziswa kabusha nezingasetshenziswa kabusha ezinciphisa imfucuza kanye nomthelela emvelweni.

Lapho bekhetha inketho yokufaka imishini yokufaka isaladi, abakhiqizi kumele bacabangele izidingo ezithile zemikhiqizo yabo, izithameli eziqondiwe, kanye nemigomo yokuzinza. Ngokusebenzisa ikhambi lokufaka elifanele, bangaletha amasaladi ahlangabezana nokulindelwe ngabathengi ukuze babe basha, babe nekhwalithi, futhi baqaphele imvelo. Ukutshala imali emishinini yokufaka isaladi esebenza kahle futhi efanelekile, kanye nenketho yokufaka efanele, kuqinisekisa ukuthi amasaladi afinyelela abathengi esimweni esihle, okufaka isandla ekwanelisekeni kwamakhasimende kanye nempumelelo yebhizinisi.
