Ngokuthuthuka okusheshayo kwemboni yokupakisha, izinto zokupakisha ezingasindi futhi kulula ukuthutha zithuthukiswa kancane kancane futhi zisetshenziswe kabanzi. Kodwa-ke, ukusebenza kwalezi zinto ezintsha zokupakisha, ikakhulukazi ukusebenza komgoqo we-oxygen kungahlangabezana nezidingo zekhwalithi zokupakishwa komkhiqizo? Lokhu ukukhathazeka okuvamile kwabathengi, abasebenzisi nabakhiqizi bemikhiqizo yokupakisha, ama-ejensi okuhlola ikhwalithi kuwo wonke amazinga. Namuhla sizoxoxa ngamaphuzu asemqoka okuhlolwa kwe-oxygen permeability yokupakishwa kokudla.
Izinga lokudluliswa komoyampilo likalwa ngokulungisa iphakheji kudivayisi yokuhlola nokufinyelela ukulingana endaweni yokuhlola. Umoya-mpilo usetshenziswa njengegesi yokuhlola kanye ne-nitrogen njengegesi elithwalayo ukwenza umehluko othile wokugxiliswa komoyampilo phakathi kwengaphandle nengaphakathi lephakheji. Izindlela zokuhlola ukupakishwa kokungena kokungena kokudla ziyindlela yengcindezi ehlukanisayo kanye nendlela ye-isobaric, esetshenziswa kakhulu indlela yengcindezi ehlukanisayo. Indlela yomehluko wengcindezi ihlukaniswe izigaba ezimbili: indlela yokuhluka kwengcindezi ye-vacuum kanye nendlela yomehluko we-pressure positive, futhi indlela ye-vacuum iyindlela yokuhlola emele kakhulu endleleni yomehluko wengcindezi. Futhi kuyindlela yokuhlola enembe kakhulu yedatha yokuhlola, enezinhlobonhlobo zamagesi okuhlola, njenge-oxygen, umoya, isikhutha namanye amagesi ukuze kuhlolwe ukungena kwezinto zokupakisha, ukuqaliswa kwefilimu yepulasitiki ejwayelekile ye-GB/T1038-2000 kanye nendlela yokuhlola ukungena kwegesi yeshidi.
Umgomo wokuhlola uwukusebenzisa isifanekiso ukuhlukanisa igumbi lokungena libe yizikhala ezimbili ezihlukene, okokuqala vala izinhlangothi zombili zesifanekiso, bese ugcwalisa uhlangothi olulodwa (uhlangothi olunomfutho ophezulu) ngegesi yokuhlola engu-0.1MPa (ukucindezela okuphelele), kuyilapho olunye uhlangothi (uhlangothi olunomfutho ophansi) luhlala lungenalutho. Lokhu kudala umehluko wengcindezi yegesi yokuhlola engu-0.1MPa ezinhlangothini zombili zesifanekiso, futhi igesi yokuhlola ingena ngefilimu iye ohlangothini lwengcindezi ephansi futhi ibangele ushintsho kwingcindezi ohlangothini oluphansi lwengcindezi.
Inani elikhulu lemiphumela yokuhlolwa libonisa ukuthi ekufakweni kobisi olusha, ukupakishwa kwe-oksijeni yokupakisha phakathi kuka-200-300, impilo yeshalofu esiqandisini cishe izinsuku ezingu-10, ukuphefumula kwe-oksijeni phakathi kuka-100-150, kuze kufike ezinsukwini ezingu-20, uma ukuphefumula komoya-mpilo kulawulwa ngaphansi kwe-5, khona-ke impilo yeshalofu ingafinyelela ngaphezu kwenyanga eyi-1; ngemikhiqizo yenyama ephekiwe, akudingeki nje kuphela ukunaka inani le-oxygen permeability yezinto ukuvimbela i-oxidation kanye nokuwohloka kwemikhiqizo yenyama. Futhi futhi unake ukusebenza komgoqo womswakama wezinto ezibonakalayo. Ngokudla okuthosiwe njengama-noodle asheshayo, ukudla okukhukhumele, izinto zokupakisha, ukusebenza okufanayo kwesithiyo akufanele kunganakwa, ukupakishwa kokudla okunjalo ukuvimbela i-oxidation yomkhiqizo kanye ne-rancidity, ukuze kuzuzwe ukungena komoya, ukufakwa komoya, ukukhanya, isithiyo segesi, njll. ngaphansi kuka-3, ukungena komswakama ku-2 elandelayo; imakethe ivame kakhulu ukupakisha igesi conditioning. Akukhona nje kuphela ukulawula inani le-oxygen ekwazi ukungena kwezinto, kunezidingo ezithile zokungena kwe-carbon dioxide.
