Nyob rau hauv lub neej txhua hnub, peb tuaj yeem pom cov khoom ntim khoom noj, deoxygenated ntim khoom noj, thiab lwm yam hauv khw malls thiab supermarkets. Cov zaub mov hauv cov ntawv ntim no pom tseeb muaj lub neej ntev dua li cov hnab ntim khoom noj zoo tib yam.
Hauv kev lag luam ntim khoom yooj yim, lub tshuab nqus tsev ntim, deoxygenated ntim thiab retort ntim yog tag nrho cov ntaub ntawv ntim ntau. Lawv muaj qee qhov sib xws tab sis qhov tseem ceeb sib txawv.
Lub tshuab nqus tsev ntim, tseem hu ua lub tshuab nqus tsev ntim, txhais tau tias tshem tawm tag nrho cov huab cua los ntawm lub pob thiab txo qhov ntim ntawm lub hnab ntim kom cov khoom ntim tuaj yeem lo rau sab hauv phab ntsa ntawm lub hnab ntim khoom tsis txav mus los, yog li zam kom tsis txhob muaj qhov xav tau ntawm cov khoom thiab lub hnab ntim khoom kom txav mus los thaum tuav thiab kev thauj mus los. Kev cuam tshuam rov qab tuaj yeem tiv thaiv oxidation ntawm cov khoom ntim thiab inhibit qhov kev loj hlob ntawm cov kab mob thiab cov kab mob anaerobic; deoxygenated ntim tsis xav kom tag nrho cov huab cua nyob rau hauv lub pob yuav tsum tau muab tshem tawm, tab sis ib tug deoxidizer yog muab tso rau hauv lub pob kom deplete oxygen Lub hom phiaj yog inhibit qhov kev loj hlob ntawm cov kab mob thiab tiv thaiv cov khoom ntim ntawm oxidized thiab deteriorated; retort ntim yog cov khoom ntim khoom siv tau yooj yim siv rau kev ua noj kub kub lossis ua kom tsis muaj menyuam. Lub tshuab nqus tsev yuav tsum tau ua thaum ntim khoom kom tsis txhob muaj huab cua nthuav dav vim cua sov thiab tawg lub hnab ntim khoom.
Los ntawm kev nkag siab saum toj no ntawm peb hom ntim, peb tuaj yeem pom meej tias lub tshuab nqus tsev ntim, deoxidation ntim, thiab retort ntim txhua yam yuav tsum tau ua cov zaj duab xis substrates nrog cov khoom zoo. Qhov txawv yog qhov sib txawv ntawm lub tshuab nqus tsev ntim khoom thiab cov khoom ntim retort. Cov qub tsis tas yuav tsum tau tiv taus qhov kub thiab txias thaum siv, thaum lub sij hawm tom kawg yuav tsum tau nqus ua ntej; nruab nrab ntawm lub tshuab nqus tsev ntim thiab deoxygenation ntim, tom kawg siv tag nrho cov pa oxygen hauv lub hnab ntim khoom. Yog li ntawd, thaum xaiv cov ntaub ntawv rau retort ntim, ntxiv rau kev xav txog cov khoom thaiv ntawm cov khoom, nws tseem yuav tsum tau xav txog tias cov yeeb yaj kiab muaj cov dej vapor permeability zoo thiab qhov kub thiab txias retort kuj.
