Yiziphi izinyathelo zokuphepha zokuthenga umshini wokupakisha we-vacuum wenyama ebandayo? Inyama ebandayo uhlobo lwenyama, eyaziwa nangokuthi inyama emuncu. Ngemva kochungechunge lokucubungula, inyama ebandayo ayikwazi nje ukuqinisekisa ubusha benyama, futhi ingandisa isikhathi sayo sokuhlala eshalofini, okubangelwa kakhulu yikhredithi yomshini wokupakisha we-vacuum wenyama ebandayo oguquliwe emoyeni. Yiziphi izici okufanele sizinake lapho sithenga imishini yokupakisha ye-vacuum yenyama ebandayo eguquliwe emoyeni? Okulandelayo, ake sixoxe ngalesi sihloko. Ake sixoxe ngakho. 1. Ukunemba kokuxuba igesi Isizathu sokuthi umshini wokupakisha we-vacuum wenyama ebandayo olawulwa emoyeni ungavala ubusha benyama sincike ekufakweni kwegesi exubile. Njengamanje, amagesi amabili e-carbon dioxide kanye ne-oxygen ngokuvamile asetshenziselwa ukuxuba inyama ebandayo ebandayo. I-oxygen ingavimbela isikhunta ukuthi singaphindaphindi lapho inyama entsha igcinwa, okwenza inyama ibe bomvu ngokugqamile esikhathini esifushane, okuyinto eyamukelwa kalula ngabathengi. I-carbon dioxide ingandisa isigaba sokulibala sokukhula kwamagciwane futhi inciphise ijubane lesigaba sayo sokukhula se-logarithmic.

I-carbon dioxide iyancibilika enyameni, yehlise i-pH yenyama futhi ivimbele ezinye izinto ezincane ezingabekezeleli i-asidi. Lawa magesi amabili adinga ukuhlanganiswa ndawonye futhi agcwaliswe ebhokisini elikhiyayo elisha. Uma ukunemba kokuxuba kwamagesi kungahlangabezani nezidingo, isikhathi sokuphelelwa yisikhathi sizoncishiswa. Ngakho-ke, kufanele kunakwe ukuxuba amagesi lapho uthenga umshini wokupakisha we-vacuum emoyeni oguquliwe wenyama entsha ebandayo. Uma ukunemba kuphakeme, kungcono. 2. Ukuqina kwebhokisi lokupakisha Ngemva kokupakisha inyama ebandayo, kudingeka kudlule ochungechungeni lwezixhumanisi zokuhamba lapho lufika kubathengi. Ngaphezu kokuhlangabezana nezindinganiso ezithile zokushisa kulesi sixhumanisi sokuthutha, elinye iphuzu elibalulekile ibhokisi lokupakisha. Ukuqina komoya, uma kukhona ukuvuza komoya ebhokisini, kuzothinta ngqo ukuqina kwenyama, ngakho-ke sidinga ukunaka ukuthi ibhokisi lokupakisha lifinyelele yini umphumela omuhle wokuvala lapho uthenga umshini wokupakisha we-vacuum we-vacuum wenyama entsha ebandayo. Ungaya efektri yenhlangano ukuze wenze ukuhlolwa nokuhlolwa okufanele ngaphambi kokwenza izinqumo ezifanele.

3. Ukukhethwa kwezinto ezisetshenziswayo zokupakisha Ekukhetheni umshini wokupakisha we-vacuum wenyama ebandayo eshintshiwe emoyeni, izinto ezisetshenziswayo zokupakisha nazo ziyiphuzu elibalulekile okudingeka silinake lapho sithenga. Izinto ezisetshenziswayo zomshini wokupakisha wenyama ebandayo eshintshiwe emoyeni kufanele zikhethwe ngezakhiwo ezinhle zokuvimba. Izinto zokupakisha ukuvimbela ukuvela kwegesi ebhokisini lokupakisha, kanye nokuvimbela ukungena komoya-mpilo emkhathini. Njengokupakisha kwenyama ebandayo eshintshiwe eshintshiwe, kuyadingeka ukuthi kube nezakhiwo ezinhle zokuvimba kokubili i-carbon dioxide kanye ne-oxygen. Ngokuvamile, kusetshenziswa amafilimu okupakisha ahlanganisiwe ane-PET, PP, PA, PVDC, njll. njengezinto eziyisisekelo. Ngokuphathelene nokuthengwa komshini wokupakisha we-vacuum wenyama ebandayo epholile, kwenziwe ukuhlaziywa okuthile namuhla ngezici ezintathu. Kusukela ekuhlaziyweni okungenhla, kungabonakala ukuthi ukuthengwa komshini wokupakisha we-vacuum wenyama ebandayo epholile kudinga ukwenziwa kuzo zonke izici. Ngemuva kokucatshangelwa okubanzi, ngaphezu kwemishini ngokwayo, izinto ezisetshenziswayo zokupakisha nazo ziyadingeka. Kuphela lapho zonke izinto zihlangabezana namazinga lapho imikhiqizo eyanelisayo ingapakishwa khona.
