Ukudla okomisiwe okufriziwe, okubuye kwaziwe ngokuthi yi-FD (Frize Omisiwe) ukudla, kunenzuzo yokugcina ukusha kwakho nokudla okunomsoco, futhi kungagcinwa ekamelweni lokushisa isikhathi esingaphezu kweminyaka engu-5 ngaphandle kwezivimbelakuvunda. Ngenxa ye-pint yayo ngaphezu kwamanzi amaningi, anesisindo esilula, ukuthwala okulula nokuthutha kanye nezinye izinzuzo, ukudla okufakwe yiqhwa futhi sekuqalile ukungena empilweni yansuku zonke ye-People's Daily, kuba ukudla okunempilo kokungcebeleka okulula.
Ngenxa yokuthi umkhiqizo osuphelile unesisindo esilula futhi kulula ukuwuthwala futhi ukuthuthwa, ukudla okufakwe iqhwa sekuqalile ukungena empilweni yansuku zonke ye-People's Daily futhi kube ukudla okulula nokunempilo kokuzilibazisa. Isidingo sokudla okufakwe yiqhwa sikhula kakhulu emhlabeni jikelele.
Ukudla okukhulu kubanda isomisi umshini imfushane ngomshini wokomisa i-vacuum ye-food, ubuchwepheshe bokomisa ukudla obuqandisiwe baqala ngeminyaka yawo-1930s, kanti umshini wamanje wokumisa ukudla ube yiqhwa usuyinto ebalulekile yokomisa ukucubungula ukudla okujulile.
Umgomo wokomisa ukudla ube yiqhwa: Ngokusekelwe ekubambisaneni nasekuguqulweni koketshezi, okuqinile kanye negesi ezifundeni ezintathu zesigaba samanzi emazingeni okushisa ahlukene nasezindaweni ze-vacuum, into yokudla equkethe amanzi iqala iqhwa ibe yisimo esiqinile, bese ngaphansi kwesimo esithile. i-vacuum degree, amanzi akuwo ahlotshiswe ngokuqondile asuka esimweni esiqinile aye esimweni segesi, ukuze asuse amanzi ukuze alondoloze indlela yokudla.
Iyunithi yokomisa ukudla ifakwe umgqomo wokumisa iqhwa, iyunithi yesiqandisi, iyunithi ye-vacuum, iyunithi yomjikelezo, iyunithi yokulawula ugesi, njll.
Ake sibheke izinzuzo zokusebenzisa umshini omkhulu wokumisa ukudla ukuze okomise ukudla kube yiqhwa:
1, ukudla komisiwe emazingeni okushisa aphansi, futhi izingxenye ezizwela ukushisa ezintweni zokudla, njengamaprotheni, ama-microorganisms nezinye izithako ze-bioactive, zingavikelwa.
2, ukomisa emazingeni okushisa aphansi, ukulahlekelwa ezinye izingxenye eziguquguqukayo entweni kuncane.
I-3, ukomisa emazingeni okushisa aphansi, ukukhula kwama-microorganisms kanye nendima yama-enzyme cishe yama, ngakho-ke indaba kuze kufike ezingeni eliphezulu ukugcina izakhiwo zangempela.
4, ukomiswa kwenziwa esimweni esingenawo umoya-mpilo we-vacuum, futhi ukucekelwa phansi kwezingxenye ezithile ezitholakala kalula ekudleni kuyancishiswa.
I-5, umshini omkhulu wokomisa ukudla omiswe yiqhwa uwomisa i-sublimation, ngemuva kokufakwa kwe-sublimation, ukudla kuhlala eshalofini leqhwa eliqandisiwe, ivolumu cishe ayishintshile ngemuva kokumiswa, ivulekile futhi ine-spongy, indawo yangaphakathi inkulu, inhle. ukubuyisela amanzi emzimbeni.
I-6, ukomisa ukudla okungama-95% kuya ku-99% wamanzi, ukuze ukudla okomisiwe kugcinwe isikhathi eside.
