Yethula njalo izinzuzo zokusetshenziswa ekudleni, ngakho-ke kunabantu abaningi abangabaza i-vacuum
umshini wokupakisha ingabekwa isikhathi esingakanani ngemva kokufakwa kwe-vacuum, noma ngabe ihambisana nokuphepha kokudla nokunye uchungechunge lwezinkinga.
Umshini wokupakisha we-vacuum ungakhipha umoya ngokuzenzakalelayo ngaphakathi kwesikhwama, ufeze ngokuphelele ngemuva kwenqubo yokuvala i-vacuum.
Ubuchwepheshe bokufaka i-vacuum baqala ngawo-1940.
Ngo-1950, ifilimu yepulasitiki ye-polyester, i-polyethylene yasetshenziswa ngempumelelo ekufakweni kwe-vacuum, kusukela ngaleso sikhathi, ukupakishwa kwe-vacuum futhi kwathuthukiswa ngokushesha.
Umshini wokupakisha we-vacuum uvame ukusetshenziswa embonini yokudla, ngoba ngemuva kokufakwa kwe-vacuum, ukudla okulwa ne-antioxidant, ukufeza inhloso yokulondolozwa kwesikhathi eside.
Inkinga ukuthi idinga ukuphumelela ukuhlolwa ukuze ithole imiphumela enembile.
Njengoba sibonile impilo yeshalofu yokupakishwa kokudla, kuphela lapho umnyango womsebenzi webhizinisi ngemuva kokuhlolwa, ingakwazi.
kodwa futhi kuwebhusayithi namuhla ukuqoqa imibuzo eminingi mayelana ne-vacuum yokupakisha impilo yeshalofu lokudla.
Umshini wokupakisha ozenzakalelayo ulungele ukusika inyama eqandisiwe, inyama ebandayo ebandayo, imikhiqizo yesoya efana nenyama, ukudla kwasolwandle, ukudla okulula, imikhiqizo yezemithi, izinto zezokwelapha, izinto zikagesi, imikhiqizo yemboni yamathuluzi e-hardware efana ne-vacuum noma igesi yokupakisha, ukupakishwa sekuphenduke umkhuba wokupakishwa kokudla esikhathini esizayo.
Ake sibheke kufanele bazi ukuthi iyiphi inhlonipho.
Izinhlobo zesikhathi seshelufu sokudla nokudla okuhlobene ne-vacuum pretreatment ngaphambi kokupakisha.
Izinhlobo ezahlukene zokudla, noma inqubo yokwelapha ehlukile, ukupakishwa kwe-vacuum kuhlukile ngemva kwesikhathi sokugcina ekamelweni lokushisa.

Ngokusekelwe kokuhlangenwe nakho, isibonelo, uma ukulondolozwa kokudla ekamelweni lokushisa izinsuku ezimbili, kungase kube imikhiqizo yezolimo emisha noma imikhiqizo yenyama egayiwe kancane.
Uma kunjalo, ngemva kokufakwa kwe-vacuum, inganwetshwa ibe yizinsuku eziyisithupha.
Ezinye zinganwetshwa zibe yizinsuku eziyi-18.
Isikhathi esihlala njalo isikhathi sokudla sifushane, izithelo ezomisiwe, ngisho nangaphezu kwezinyanga eziyi-12.
Uzoqhuba isilingo somkhiqizo othile.
okulandelayo ngokuyinhloko mayelana nesimiso sokugcinwa kokupakisha kwe-vacuum, ukuze uqonde inkinga yokuphila kweshalofu: i-vacuum packing isebenzisa i-oxygen yimisebenzi eyinhloko yomshini wokupakisha we-vacuum, ukuze kuvinjwe ukubola kokudla, isimiso silula.
Ngoba ukuwohloka komkhuhlane wokudla kubangelwa ikakhulukazi umsebenzi we-microorganism, kanye nama-microorganisms amaningi (
Njengesikhunta nemvubelo)
Izidingo zokuphila zomoya-mpilo, kanye nokupakishwa kwe-vacuum ukusetshenziswa kwalesi simiso.
Ukudla kwesikhwama kanye ne-oxygen kumaseli kususiwe, i-microbe ilahlekelwe yayo & nezinye
Imvelo & kuyo yonke;
.
Imiphumela ibonisa ukuthi lapho ukuhlushwa komoya-mpilo esikhwameni kube ngaphansi kuka-1%, ukukhula kwezinga lokuzala kwe-microbial kwehle kakhulu, ukuhlushwa komoyampilo & le;
Kuzero.
I-5%, ama-microorganisms amaningi avinjelwe, ayeke ukuzala.
Qaphela: ukupakishwa kwe-vacuum kungavimbela ukuzalana kwebhaktheriya ye-anaerobic kanye nokusabela kwe-enzyme okubangelwa ukonakala kokudla, ngokuqandisa, ukubanda, ukuphelelwa amanzi emzimbeni, ukuvalwa kwe-high-temperature, ukuvalwa kwe-irradiation, ukuvalwa kwe-microwave, usawoti kanye nezinye izindlela ezisizayo.
I-vacuum deaerating ingavimbeli nje ukukhula kokuzalanisa amagciwane, omunye umsebenzi obalulekile ukuvimbela i-oxidation yokudla, ngoba ukudla okunamafutha kuqukethe ama-acids amaningi angasetshenzisiwe, i-oxidation nge-oxygen, yenza ukunambitheka kokudla kube metamorphism.
Ngaphezu kwalokho, i-oxidation yenza futhi u-vitamin A no-vitamin C ukulahlekelwa, i-pigment yokudla engazinzile ngaphansi kwethonya lomoya-mpilo, yenza umbala ube mnyama.
I-oksijeni ingavimbela ngokuphumelelayo ukonakala kokudla, ngakho-ke, gcina umbala wayo, iphunga, ukunambitheka kanye nenani lokudla okunomsoco.
Uma nje ingafinyelela izinga elithile le-vacuum, umphumela uyafana.
Ukuthola akudingekile ukuba kubize, kudle isikhathi, noma kube nzima. Konke kuza endleleni efanele kanye ne-checkweigher endaweni.
Wonke amasu esikhathi eside kanye nezenzo zesikhathi esifushane ze-Smart Weigh zizololongwa isethi yamanani angumongo abiwa yilowo nalowo ozakwabo.
weigher idayiswa oversees emakethe futhi ine idumela eliphezulu. Ngaphandle kwalokho, imikhiqizo yethu ithengiswa ngamanani aphusile.
