Umshini wokupakisha i-concave vacuum usekelwe emshinini wokupakisha wangempela wokucaciswa okufanayo ukuze ujulise igumbi le-vacuum, futhi ngesikhathi esifanayo, umklamo we-concave ungavimbela isobho namanzi ukuthi aphume emishini.Imbobo echichimayo inikezwa ngaphansi komsele ongezansi.Ingahlanzwa njalo.Ngokuvamile, amaphampu evacuum afakwe lo mshini makhulu uma kuqhathaniswa, okungenani angama-cubic metres angama-60 ngehora noma ngaphezulu.
Umshini wokupakisha we-vacuum ovuselelwe ulungele: ukucutshungulwa kwenyama, imikhiqizo yasemanzini, ukucubungula ukudla kwasolwandle, izithelo ezigciniwe, okusanhlamvu, imikhiqizo kabhontshisi wesoya, izinto zokwelapha, izinto zikagesi, ukucubungula imifino, imikhiqizo yamakhemikhali nezinye izinto eziqinile, ezingaqinile, impushana nezinye izinto zokuhlanza. ukupakisha.Ingavimbela umkhiqizo ekufakweni kwe-oxidation, isikhutha, ukonakala, nobufakazi bomswakama ukuze kunwetshwe isikhathi sokugcina somkhiqizo.
Izinzuzo eziyinhloko yilezi:
1.Ingxenye yomoya (i-oksijeni) ephaketheni iyaqedwa, engavimbela ngokuphumelelayo ukudla ukuthi kungonakali.
2.Ukusetshenziswa kwezinto zokupakisha ezinezakhiwo ezinhle kakhulu zokuvimbela (ukuqina komoya) kanye nobuchwepheshe bokubeka uphawu oluqinile kanye nezidingo kungavimbela ngokuphumelelayo ukushintshaniswa kokuqukethwe kokupakisha, okungavimbela ukulahlekelwa kwesisindo sokudla nokulahlekelwa ukunambitheka, nokuvimbela ukungcola kwesibili.
3.Igesi engaphakathi kwesitsha sokupakisha i-vacuum isusiwe, okusheshisa ukudluliswa kokushisa, okungathuthukisa ukusebenza kahle kokushisa inzalo futhi kugweme isitsha sokupakisha ukuthi singaqhumi ngenxa yokwanda kwegesi ngesikhathi sokushisa inzalo.Embonini yokudla, izicelo zokupakisha i-vacuum zivame kakhulu, imikhiqizo ehlukahlukene ephekwe njengemilenze yenkukhu, i-ham, amasoseji, izibopho zezinhlanzi eziboshwe, i-beef jerky, njll;imikhiqizo egciniwe efana nama-pickle ahlukahlukene, imikhiqizo ye-soy, izithelo ezigciniwe nokunye ukudla okudingeka kugcinwe kuhlanzekile Ngokukhulayo, ukupakishwa kwe-vacuum kusetshenziswa.Ukudla okufakwe ivacuum kunesikhathi eside seshelufu, okwelula kakhulu isikhathi sokudla sokudla.
Ngaphezu kokulawula ukukhula nokukhiqizwa kabusha kwama-microorganisms, i-vacuum deoxygenation yomshini wokupakisha we-vacuum ophelile unomunye umsebenzi obalulekile wokuvimbela i-oxidation yokudla.Ngenxa yokuthi amafutha namafutha aqukethe inani elikhulu lama-acids angama-unsaturated, afakwa i-oxidized ngesenzo somoya-mpilo, okwenza ukudla kunambitheke futhi kubi.Ngaphezu kwalokho, i-oxidation iphinde ibangele ukulahlekelwa uvithamini A no-C, futhi izinto ezingazinzile ezinemibala yokudla zithintwa umoya-mpilo ukuze kube mnyama umbala.
Isiphi isimo esikhethekile sokukhetha umshini wokupakisha we-concave vacuum?
1.Uketshezi ludlula ingxenye eyodwa yesikhwama.Ngaphansi kwezimo ezijwayelekile, kunomswakama othile esikhwameni ongadingi ukusebenzisa imodeli ehlehlisiwe.Kuphela uma umswakama udlula ingxenye eyodwa yesikhwama, imodeli ehlehlisiwe iyadingeka.Usayizi othize ohlehlisiwe unqunywa usayizi we-athikili.
2.Izinto eziwugqinsi.Lesi yisimo wonke umuntu angasiqondi kakhulu.Imvamisa, imikhiqizo eqinile ayidingi ukusebenzisa amamodeli we-concave, kepha uma izinto zishubile, umugqa wokuvala awukwazi ukuba sekupheleni kwento lapho umshini wokupakisha we-vacuum wohlobo lwesikhulumi usetshenziselwa ukuvala uphawu.Lapho ubeka i-centering, udinga ukusebenzisa imodeli ye-concave ukuze uqinisekise isikhundla somugqa wokuvala, ukuze uzuze umphumela ophelele wokupakisha.
3.Imikhiqizo yesoso.Iphuzu lokuqala esikhuluma ngalo nge-liquid ngokuyinhloko umkhiqizo oqukethe uketshezi, njenge-mustard tuber Ukugeleza endaweni yokuvala, ngaleyo ndlela kuthinte umphumela wokuvala, kulokhu, kuyadingeka ukusebenzisa umshini wokupakisha we-vacuum ophelile.
