Ukuthuthukisa Ukupakishwa kwe-DJVAC: Ukukhetha Izinto Ezifanele Zesikhwama Sokuhlanzwa

Ukubuka Konke Kokupakisha I-Vacuum kanye Nezinto Zesikhwama

Imishini yokupakisha i-vacuum (igumbi or izinhlobo zokumunca) khipha umoya ezikhwameni noma emakamelweni omkhiqizo ngaphambi kokuvala izikhwama ukuze uvimbele amagesi angaphandle. Lokhu kwandisa kakhulu isikhathi sokuphila kweshalofu ngokunciphisa ukuvezwa komoya-mpilo nokuvimbela ukukhula kwamagciwane abolayo, ngezikhwama ze-vacuum ezikhethwe ngokusekelwe ezicini ezifana nezakhiwo zokuvimbela, ukuqina kanye nokusebenza kokuvala ukushisa - ngokuvamile ama-laminate epulasitiki e-laminate amaningi akhethwa ngokusekelwe ezicini ezithile ezifana nokuvikelwa kokuvimbela umoya-mpilo/umswakama, ukumelana nokushisa, ukucaca kanye nokuqina kokubhoboza.

Izikhwama Zokushaja Ezine-Nylon/PE (PA/PE)

* Ukwakheka Nezakhiwo: Izikhwama ze-PA/PE zinesendlalelo sangaphandle se-nylon (polyamide) esinamathiselwe kungqimba lokuvala lwangaphakathi lwe-polyethylene ukuze kuvikelwe ukubhoboza, kuvikelwe ukuvinjelwa komoya-mpilo/iphunga kanye nezivalo zokushisa eziqinile ngisho nasemazingeni okushisa aphansi kunamafilimu e-PE alula. Uma kuqhathaniswa namafilimu e-PE alula, ama-laminate e-PA/PE anezivalo zomoya-mpilo/iphunga eziphakeme kakhulu kanye nokumelana nokubhoboza, egcina ubukhulu bawo kuzo zonke izinqubo zokushisa ezibandayo ngenkathi ebekezelela ukushisa okuphakathi ngesikhathi sezinqubo zokuvala.

* Izicelo: Amaphakethe e-PA/PE avame ukusetshenziselwa imikhiqizo yenyama emisha neqandisiwe (inyama yenkomo, ingulube, inkukhu kanye nokudla kwasolwandle) ngenxa yokuthi imiphetho yamathambo nezingcezu ezibukhali azikwazi ukumelana ne-nylon; lokhu kusiza ukugcina umbala nokunambitheka kwawo ngesikhathi sokugcina isikhathi eside ebanda. Alungele futhi imikhiqizo yoshizi neye-deli ukuze kulondolozwe ukunambitheka nokuthungwa ngokusika ukungena komoya-mpilo; ifilimu yawo eqinile ingapakisha ngisho nenyama ecutshunguliwe njenge-pate. Amasosi ange-semi-liquid angadluliswa nasezikhwameni ze-PA/PE ngenxa yezendlalelo eziqinile zokuvala ezivimbela ukuvuza ngenkathi zigcina amaphunga - afanele isikhathi eside sokugcina ebanda! Ngamafuphi, amaphakethe e-PA/PE afanele ukudla okunemiphetho engajwayelekile noma eqinile (amathambo/ama-chips ama-chips enyama ama-chips enyama), kudingeka isikhathi eside sokuqandisa/sokuqandisa - aphelele!

* Okunye Ukusetshenziswa: Ama-laminate e-PA/PE anezinye izinhlelo zokusebenza eziningi ngaphandle kokudla, njengokupakisha kwezokwelapha kanye nezingxenye zezimboni. Ifilimu yawo enezivikelo eziphakeme ingahlanzwa futhi ivalwe ukuze kudalwe amakhithi ezokwelapha; ukupakisha kwe-elekthronikhi kuyisebenzisela ukulawula umswakama ngenkathi kungezwa amandla omshini kuyilapho izendlalelo ezilwa nokungaguquguquki noma izithiyo zingase zengezwe kumabhodi wesekethe noma ukupakisha kwehadiwe. Ekugcineni, izikhwama ze-PA/PE zinikeza ifilimu ethembekile yokusebenza enamandla okuvimbela okuphezulu kanye nokumelana nokubhoboza, okwenza kube ukukhetha okuphezulu kwezidingo zokupakisha ezijwayelekile ze-vacuum.

Izikhwama Zokushaja Ezisebenzisa I-Polyester/PE (PET/PE)

*Ukwakheka Nezakhiwo: Amaphakethe e-Polyester/PE (avame ukubizwa ngokuthi amaphakethe e-PET/PE noma e-PET-LDPE) asebenzisa ungqimba lwangaphandle lwe-PET olunengqimba yangaphakathi ye-PE yokwakheka kwawo. I-PET inikeza izithiyo ezinhle kakhulu zamakhemikhali, ukushisa kanye nomoya-mpilo futhi amandla ayo aphezulu ngokuphindwe ka-5-10 kunamandla okudonseka e-PE; ngaphezu kwalokho ingagcina izakhiwo zomzimba ebangeni elibanzi lokushisa, okwenza lezi zikhwama zibone kahle ngamakhono okuvimbela aphakathi nendawo (anikeza ukucaca ngokumelana nokubhoboza okuphakathi nendawo; kodwa ezintweni ezinamaphuzu abukhali kakhulu kungangcono ukusebenzisa izendlalelo ze-nylon).

* Izicelo: Izikhwama zokuhlanza ze-PET/PE zilungele izinto ezidinga ukucaca kanye nokumelana namakhemikhali, njengenyama ephekiwe noma ebhemayo kanye nenhlanzi edinga ukubonakala ngezinkinga zekhwalithi yokupakisha. Ukuqina kwazo kwenza kube lula ukuvala ukushisa emishinini ezenzakalelayo; ngenxa yezakhiwo zokuqina kwezinga lokushisa ze-PET, zisebenza kahle ngokulinganayo ezindaweni eziqandisiwe njengezizungezile (isb. ubhontshisi wekhofi ogcwele i-vacuum noma izinongo). Ngaphezu kwalokho zivame ukusetshenziswa njengamafilimu aphezulu emigqeni yokupakisha ye-vacuum ye-thermoforming (kusetshenziswa ama-webs okwakha i-PA/EVOH/PE).

* Inothi Lobuchwepheshe: Isithiyo esinamandla se-Polyester kumagesi sisiza ukugcina iphunga, kodwa i-PET/PE emsulwa ayinayo isithiyo esijulile se-oxygen kanye nokuqina kokubhoboza kwe-PA/PE. Ngakho-ke, i-PET/PE ingase ithandeke kakhulu kumasobho agcwele i-vacuum, ama-powder, kanye nokudla okulula ngenxa yokwakheka kwayo okuthambile noma okulula; i-carePac iphawula ukuthi izendlalelo ze-polyester noma ze-nylon eziqinile zivimbela ukubhoboza ngenkathi zenza i-PET/PE ifaneleke ukuvalwa kwe-vacuum. Emsebenzini abaningi abaprosesa bakhetha i-PET/PE yemikhiqizo yesikhathi esiphakathi eshelufini enezindwangu ezimboziwe (uma besebenzisa imishini yokumunca) ukuze bathuthukise amakhono okuvala; lezi zikhwama zisebenza kahle kakhulu lapho amayunithi ekamelo (amazinga aphezulu e-vacuum kungenzeka). Izikhwama ze-PET/PE ziyahambisana nayo yonke imishini yokufaka i-vacuum; amayunithi ekamelo aphumelela kakhulu ekukhiqizeni amazinga e-vacuum amakhulu kuneminye imishini yokufaka i-vacuum (amazinga aphezulu e-vacuum kungenzeka).

Amafilimu Anezingqimba Eziningi Ezinezithiyo Eziphakeme (i-EVOH, i-PVDC njll.)

Amafilimu Anezingqimba Eziningi Ezinezivikelo Eziphezulu (i-EVOH, i-PVDC njll.) ahlinzeka ngesivikelo esisebenzayo ekungeneni kwezinto ezingcolisayo eziyingozi emvelweni.

*Izikhwama Ezisekelwe ku-EVOH: Ukuze kube nesikhathi esiphezulu seshelufu, ama-laminate anezingqimba eziningi afaka i-EVOH (ethylene-vinyl alcohol) barrier resin ahlinzeka isikhathi esiphezulu seshelufu kanye nokuvimbela ukulahleka komkhiqizo. Izakhiwo ezivamile zala ma-laminate yi-PA/EVOH/PE noma i-PE/EVOH/PE, lapho i-EVOH core ihlinzeka ngesilinganiso esiphansi kakhulu sokudlulisa umoya-mpilo kuyilapho i-nylon noma i-PET inikeza amandla omshini kanye nokuvaleka – le nhlanganisela iveza isithiyo esiphezulu: Izikhwama ze-EVOH zinciphisa kakhulu ukufuduka kwe-oxidation kanye nomswakama ngenkathi ngesikhathi esifanayo zengeza amandla omshini. Ngokusho kwemibiko yochwepheshe, la ma-laminate asiza ekufezeni isikhathi eside seshelufu esiqandisiwe noma esiqandisiwe ngenkathi ngesikhathi esifanayo kunciphisa ukulahleka komkhiqizo uma kuqhathaniswa nama-laminate e-PA/PE.

*Izakhiwo: Ifilimu ye-EVOH icacile futhi iyaguquguquka, kodwa ezikhwameni ze-vacuum ivame ukufihlwa yizingqimba ezingacacile eziyisitha. Lezi zikhwama zigcina ubuqotho besivalo ngesikhathi sokuqandisa kuyilapho i-PE ivikela i-EVOH ekulimaleni komswakama; ukuqina kwazo kokubhoboza okuvela ezingqimbeni ze-PA kuvame ukwedlula okwama-PA/PE alula ngaphandle kokwehlisa amandla esivalo.

* Izicelo: Izikhwama ze-vacuum ze-EVOH ezinezivimbelo eziphakeme ziyindlela ekahle yokuthumela inyama entsha/eqandisiwe kanye nokudla kwasolwandle amabanga amade nokugcina isikhathi eside. Izikhwama ze-vacuum ze-EVOH nazo ziyindlela enhle yokuvikela ukudla okunenani eliphezulu noma okuzwela umoya-mpilo njengoshizi, amantongomane, izithelo eziphelelwe amanzi noma ukudla okulungiselelwe okuphezulu kanye namasosi ekulahlekelweni umoya-mpilo noma ekonakalisweni ngesikhathi sokuthuthwa noma sokugcina. Isikhwama se-EVOH kufanele sicatshangelwe njalo lapho ukulondolozwa kwekhwalithi (umbala, ukunambitheka noma ukuthungwa) kufanele kugcinwe; ngamanye amazwi zisebenzise noma nini lapho imikhiqizo ye-sous vide idinga izimo ezinhle kakhulu ezidingweni zokuthutha noma zokugcina impahla isikhathi eside!

*Ezinye Izithiyo: Amafilimu ambozwe nge-PVDC asetshenziswa kwezinye izikhwama zoshizi noma zenyama ezicoliwe anikeza ukungena okuphansi kwe-O2; noma kunjalo, izinkinga zomthetho kanye nokucubungula zinciphise ukusetshenziswa kwawo. Amafilimu ensimbi afakwe nge-vacuum (i-PET noma i-PA embozwe nge-aluminium) nawo athuthukisa ukusebenza kwezithiyo (bheka isigaba esilandelayo).

Izikhwama Zokushaja Ezine-Aluminium Foil (Ezenziwe Ngensimbi)

Ikhofi, itiye noma izinongo zokupakisha nge-vacuum zivame ukuhilela izikhwama ezifakwe i-aluminium laminated ukuze kuvikelwe kahle. Izendlalelo ze-aluminium foil ngaphakathi kwesikhwama zidala isithiyo esisebenzayo ekukhanyeni, umoya-mpilo kanye nomswakama - kuhle kakhulu ukugcina ikhofi isha isikhathi eside! Izikhwama ezijwayelekile ze-foil-vacuum zinezendlalelo ezintathu ezisebenza ukuvimba ukukhanya, umoya-mpilo kanye nomswakama: I-PET/AL/PE noma i-PA/AL/PE - ifilimu yangaphandle ye-PET inikeza ukumelana nokubhoboza ngenkathi amandla okubhoboza kuyilapho i-AL foil ivimba igesi kanye nokukhanya kuyilapho i-PE iqinisekisa ukuvalwa kokushisa okuhlanzekile - umphumela uwukuthi cishe akukho moya noma umswakama ongadlula!

* Izakhiwo: Izikhwama ze-aluminium-laminate zingaba ziqinile kodwa zibe nokwakheka; zibonisa ukushisa nokukhanya, zivikele emisebeni ye-UV kanye nokushintsha kwezinga lokushisa, kuyilapho zihlala zingacacile ukuze okuqukethwe kuhlale kufihliwe kuyilapho imikhiqizo ihlala yomile futhi ingangcoliswanga. Ngaphezu kwalokho, izikhwama ze-aluminium laminate zisebenza kahle ngokulinganayo eziqandisini ezijulile noma ezindaweni zokugcwalisa ezishisayo (qaphela ukuthi izikhwama ze-foil azikwazi ukuphepha kuhhavini ngaphandle kokwelashwa okukhethekile).

* Ukusetshenziswa: Izikhwama ze-foil zingasetshenziswa ukuvikela izinto ezibiza kakhulu noma ezibola kakhulu njengekhofi netiye (ukugcina iphunga nokusha), ukudla okomisiwe noma okufakwe i-powdered, amantongomane, kanye namakhambi. Ezindaweni zokudla, izikhwama ze-sous vide/boil-in-bag zivame ukusebenzisa i-foil; zilungele imithi/amavithamini/izithasiselo/amavithamini njll. Ngaphezu kwalokho, amaqabunga etiye agcwele i-vacuum avame ukugcina ukunambitheka kwawo isikhathi eside uma egcinwe ku-foil laminate uma kuqhathaniswa nokupakishwa kwepulasitiki (isibonelo) okuboniswe lapha kuyisibonelo nje!

* Ukuhambisana Komshini: Izikhwama ze-aluminium foil zivame ukuba bushelelezi futhi ngezinye izikhathi zivalwa kusetshenziswa imishini enzima, okwenza imishini yokupakisha yangaphandle ye-DJVAC ifaneleke ukuphatha lezi zikhwama ngaphandle kwenkinga.

Izicelo Zezimboni Nezokugcinwa Kwemininingwane.

Izikhwama zokuhlanza ezivimbe kakhulu zinikeza ukusetshenziswa okuningi kunokudla nje kuphela:

Izingxenye Ze-elekthronikhi Nezensimbi: Njengoba kuphawuliwe ngaphambilini, izikhwama ze-vacuum zezingxenye ze-elekthronikhi nezensimbi zivikela izingxenye ezizwela umswakama ngesikhathi sokuthunyelwa. Uma zihlanganiswa ne-desiccant, izindawo ze-vacuum zinikeza indawo engenawo umoya ongcolile noma ukugqwala kwezingxenye zensimbi. Ngokungafani nokudla, izikhwama ze-vacuum ze-PA/PE noma ze-foil nazo zingahlanzwa nge-nitrogen ngaphambi kokuvala kusetshenziswa imishini ye-DJVAC enezibambo nezilawuli ezifanele zokuphatha izikhwama ze-foil noma ze-aluminium ezijiyile.

* Ukulondolozwa Kwamadokhumenti: Ukuze kugcinwe amadokhumenti ngendlela efanele, ama-archive ngokuvamile asebenzisa amafilimu angangenisi umoya avaliwe nge-vacuum njenge-polyethylene noma amafilimu e-polyester/Mylar ukuvimba umoya-mpilo nezinambuzane, okudala izikhwama ezingangeni moya ukuze kugwenywe ukuphuzi nokukhula kwesikhunta kumadokhumenti ephepha. Njengoba kunjalo ngokupakishwa kokudla, ukuvimbela umoya-mpilo kwandisa isikhathi sokuphila - iphakheji engangeni moya yandisa isikhathi sokuphila kwamadokhumenti njengoba nje ikwandisa nemikhiqizo yokudla.

* Imithi kanye Nezokwelapha: Ama-kit ezokwelapha ahlanzekile kumele avalwe nge-vacuum kusetshenziswa izikhwama ezinezivikelo eziphakeme ezinezikhwama ze-PA/PE eziqukethe izikhala zokudabuka ukuze kube lula ukuvula izikhala zokudabuka, ngokuhambisana nezindinganiso ze-FDA noma zezokwelapha.

Kuzo zonke lezi zimo, kubalulekile ukusebenzisa ifilimu elinganiswe ngokwendawo yomkhiqizo (isibonelo, engena-halogen yamadokhumenti e-elekthronikhi noma amadokhumenti ekhwalithi yokugcina). Imishini ye-vacuum ye-DJVAC ingahlanganisa osayizi abahlukahlukene be-laminate yezikhwama; amakhasimende kufanele asho ukuthi iyiphi ifilimu ayidingayo lapho ebeka ama-oda nathi.

Indlela Yokukhetha Izinto Zesikhwama Sokuhlanza I-Vacuum

Cabanga ngalezi zici lapho ukhetha izinto zesikhwama se-vacuum:

*Izidingo Zokuvimba: Yiziphi izimo okumele umkhiqizo uhlale umusha kuzo? Ngezicelo zesikhashana zokuqandisa, izikhwama ezijwayelekile ze-PA/PE noma ze-PET/PE zinganele; ukuze kugcinwe iqhwa izinyanga noma imikhiqizo ebucayi kakhulu edinga ukuvikelwa ekudlulisweni komoya-mpilo sebenzisa ama-laminate e-EVOH anezinga lokudlulisa le-O2 eliphansi kakhulu esikhundleni salokho.

* Ukuvikelwa Kwemishini: Ingabe into yakho izoba nemiphetho ebukhali noma izophathwa kabi? Beka phambili ukumelana nokubhoboza (ama-laminate acebile nge-nylon noma ukuthungwa okuhlanganisiwe). Izingxenye ezinkulu zezimboni noma inyama emathanjeni zidinga amafilimu aqinile.

* Indlela Yokuvala: Izikhwama zokuhlanza zisebenzisa ukuvala ukushisa njengendlela yazo eyinhloko yokuvala. I-PE (LDPE noma i-LLDPE) ivame ukusetshenziswa njengento yokuvala, idinga izinga lokushisa lokuvala elifana nelemigoqo yokushisa yomshini wakho ukuze kutholakale imiphumela efanele yokuvala. Amanye amafilimu okuvimba okuphezulu angadinga amazinga okushisa aphezulu okuvala noma ingcindezi enkulu yokuvala ukuze kunamathele kahle.

* Ukuphepha Kokudla Nemithethonqubo: Sebenzisa amafilimu okudla avunyiwe yi-FDA/GB lapho uhlinzeka ngezimpahla ezimakethe zakwamanye amazwe; i-DJVAC isebenza nabahlinzeki bezikhwama abanikeza izinto eziqinisekisiwe zale njongo. Lapho uthengisa amafilimu ahambisana namazwe angaphandle, kungadingeka nemibhalo yokuthobela imithetho.

* Ukuhlaziywa Kwezindleko/Ukusebenza: Izikhwama ze-EVOH noma ze-foil ezinezithiyo eziphakeme zivame ukubiza kakhulu; hlola ngokucophelela intengo yazo uma kuqhathaniswa nezidingo zesikhathi sokuphelelwa yisikhathi - isibonelo, amantongomane afakwe i-vacuum ahloselwe ukuthunyelwa kwamanye amazwe angafanela lesi sitayela kuyilapho amafriji asekhaya angase athande izikhwama ze-PA/PE ezilula esikhundleni salokho.

Abaprosesa bavame ukwenza izivivinyo besebenzisa izikhwama zesampula ezinikezwa abakhiqizi, kuyilapho abanye beze banikeze ama-roll noma amashidi ezivivinyo kumakhasimende ukuze kuvivinywe amakhasimende. Uma udala isakhiwo osidingayo kumkhiqizo wakho (isb. “izingcezu zenkukhu eziqandisiwe”), sicela ucacise isikhathi sokuphelelwa yisikhathi esifiselekayo, indlela yokupakishwa kanye nesikhathi sokuphelelwa yisikhathi esifiselekayo ukuze usize ekunqumeni isakhiwo esinconywayo.

Isiphetho

Imishini yokupakisha i-vacuumzingamathuluzi ahlukahlukene, kodwa ukuze zisebenze kahle zidinga izinto ezifanele zesikhwama. Imishini yokupakisha ye-vacuum ye-DJVAC ingasebenzisa zonke izinhlobo zesikhwama ezinkulu ezitholakalayo - kusukela kumaphakethe ajwayelekile e-PA/PE kanye nezikhwama ze-EVOH ezivimbe kakhulu kuze kufike kuma-laminates e-foil aqinile. Abakhiqizi bangaqinisekisa ikhwalithi yomkhiqizo kanye nokusebenza kahle ngokuqonda izakhiwo zezinto ezifana namandla okuvimba, ukumelana nokushisa kanye nokuqina kokubhoboza kanye nokuzihlanganisa nezicelo zazo (inyama, ushizi, ikhofi noma amantongomane, isibonelo). Ngokuqonda nokufanisa lokhu nezicelo ezifana nokukhiqizwa kwenyama noma ukucubungula ushizi isibonelo. Ukusebenzisa isikhwama esifanele nomshini ngamunye (oqoshiwe uma kuqhathaniswa nesicaba, igumbi uma kuqhathaniswa nokumunca) kusiza ukukhulisa izinga le-vacuum kanye nokuqina kokuvala. Ekugcineni, uma usebenzisa umshini wokupakisha we-vacuum we-DJVAC, khetha izinto zesikhwama ezinikeza ukuvikelwa okwanele komkhiqizo ngenkathi uhambisana nomklamo wawo.
