I-vest bag luhlobo lwengxowa yeplastiki eqhelekileyo.Ngokuphathelele kutheni kuthiwa "isikhwama se-vest", njengoko igama libonisa, lichongwa ngokubonakala kwalo: ukuma kwalo kufana ne-vest, ngoko ke igama.Isikhwama se-vest silula ukwenza kwaye sinoluhlu olubanzi lokusetyenziswa.Kuye kwaba yimfuneko eyimfuneko kubantu kubomi bemihla ngemihla kwaye ibonelela abantu ngokulula okukhulu.
Umda wokusetyenziswa kwengxowa ye-vest: Okokuqala, isetyenziswa kwiivenkile ezinkulu kunye neevenkile ezinkulu.Ngokuqhelekileyo yahlulahlulwe ngokweesayizi ezintathu ezinkulu, eziphakathi kunye nezincinci.Iprintwe kunye neepateni zoshicilelo ezigqwesileyo kunye nombhalo.I-LOGO yeevenkile zamatsheyina kwilizwe lonke kufuneka ihambelane, kunye neemfuno zomgangatho ophezulu kwaye kwangaxeshanye.Iyahambelana nokusingqongileyo.Okwesibini, isetyenziswa kwiivenkile zoluntu eziluncedo.Ngenxa yesi sizathu, iimfuno zayo zomgangatho nazo ziphezulu, kodwa ubuninzi obusetyenzisiweyo buncinci, kwaye i-LOGO nayo ishicilelwe.Ezinye iingxowa ze-vest ezingashicilelwanga kwakhona zithengiwe, kwaye ezinye azihambelani nokusingqongileyo, ngoko akukhuthazwa.Eyesithathu yeyeemarike zamafama, eziziingxowa zevest ezisingqongileyo, eziquka ezibomvu, ezimnyama nezimhlophe.
Umsebenzi oyintloko wesikhwama se-vest kukususa i-oksijini kunye nokukhusela ukutya ekonakalisweni.Umgaqo ulula: ukonakala kokutya kubangelwa ikakhulu ngumsebenzi we-microorganisms, kwaye uninzi lwe-microorganisms (ezifana nokungunda kunye negwele) zifuna i-oksijini ukuze ziphile.Kwipakethe ye-vacuum, lo mgaqo usetyenziselwa ukususa i-oksijini kwiingxowa zokupakisha kunye neeseli zokutya, ngaloo ndlela zilahla i-microorganisms kwindawo yazo yokuhlala.
Iimvavanyo zibonisa ukuba: xa i-oxygen concentration kwi-bag ye-vest ingaphantsi okanye ilingana ne-1%, ukukhula kunye nokuzala kwesantya se-microorganisms kuya kuhla ngokukhawuleza.Xa i-oxygen concentration ye-vest bag i-≤0.5%, ezininzi ii-microorganisms ziyakuyeka ukuphindaphinda.
Ingxowa ye-vest ihlangabezana neemfuno zabantu ezifanelekileyo kunye nezikhawulezayo zengqondo kwimveliso kunye nobomi.Nangona isikhwama sincinci, umsebenzi wayo wokuthwala umthwalo uyabonakala, yingakho ithandwa kubomi bemihla ngemihla.
