Cov txheej txheem ua haujlwm ntawm lub tshuab nqus tsev ntim khoom noj

Cov txheej txheem ua haujlwm ntawm lub tshuab nqus tsev sealing khoom noj yog raws li nram no:

Lub hau ntawm lub tshuab nqus tsev, lub twj tso kua mis nqus tsev, lub tshuab nqus tsev pib nqus cua mus rau hauv lub xeev nqus tsev, lub hnab nyob hauv lub tshuab nqus tsev tib lub sijhawm, lub ntsuas lub tshuab nqus tsev kom nce mus rau lub tshuab nqus tsev uas tau ntsuas (Los ntawm lub sijhawm relay ISJ tswj) Lub twj tso kua mis nqus tsev tsis ua haujlwm, thiab lub tshuab nqus tsev nres. Hauv lub tshuab nqus tsev, tib lub sijhawm ua haujlwm ntawm ob txoj haujlwm 3-txoj kev sib nqus valve (IDT, lub tshuab nqus tsev kub sealing, thermal nyob rau hauv situ.

Lub tshuab nqus tsev ntim khoom noj khoom haus yog lub luag haujlwm tseem ceeb ntawm cov pa oxygen, nws muaj txiaj ntsig zoo rau kev tiv thaiv kev puas tsuaj ntawm cov khoom noj, nws lub hauv paus ntsiab lus yooj yim, vim tias cov khoom noj khoom haus metamorphism ua rau pwm feem ntau yog los ntawm kev ua haujlwm ntawm cov kab mob me me, thiab feem ntau cov kab mob me me (xws li pwm thiab poov xab) Kev ciaj sia yog xav tau oxygen, thiab siv lub hauv paus ntsiab lus no, cov khoom ntim thiab cov khoom noj khoom haus hauv lub cell oxygen pa luam yeeb, poob qhov chaw ciaj sia ntawm cov kab mob me me. Cov txiaj ntsig ntawm kev sim qhia tau tias: thaum qhov concentration ntawm cov pa oxygen hauv cov khoom ntim & le; 1%, kev loj hlob ntawm cov kab mob me me thiab kev yug me nyuam poob qis, qhov concentration ntawm cov pa oxygen & le; 0.5%, feem ntau cov kab mob me me yuav raug tswj hwm thiab tsis txhob yug me nyuam. (Ceeb toom: kev ntim khoom nqus tsev tuaj yeem tiv thaiv cov kab mob anaerobic yug me nyuam thiab cov tshuaj tiv thaiv enzyme los ntawm cov khoom noj khoom haus metamorphism thiab discoloration, yog li tseem yuav tsum tau ua ke nrog lwm txoj hauv kev pab, xws li kev khaws cia txias, khov, qhuav dej, kub siab sterilization, irradiation sterilization, microwave sterilization, salting, thiab lwm yam.)
