Kev ntim khoom yooj yim npaum li cas tuaj yeem txo cov khoom pov tseg thiab carbon emissions
Cov khoom pov tseg feem ntau tsis yog los ntawm 'cov zaub mov tsis zoo'
Nws yog tshwm sim los ntawm lub sijhawm, raug, thiab tuav - zaub mov tuaj yeem qhuav, oxidize, xau, raug crushed, lossis poob zoo tom qab qhib. Tias yog vim li cas cov ntim khoom noj tau yooj yim tau dhau los ua ib qho cuab yeej zoo tshaj plaws los txo cov khib nyiab hauv cov khoom siv niaj hnub no.
Vim li cas lub ntim ntim tau yooj yim siv tau
Cov neeg feem ntau ntseeg tias kev ntim khoom yooj yim yog rau kev yooj yim. Qhov tseeb, nws qhov txiaj ntsig loj tshaj plaws yog kev tswj xyuas engineering. Cov neeg tsim khoom tuaj yeem kho cov qauv ua yeeb yaj kiab kom ua tau raws li cov khoom yuav tsum tau ua: barrier, sealing zog, toughness, los yog kub tsis kam.
Cov hauv qab no yog cov chaw uas cov ntaub ntawv ntim khoom noj yooj yim yog qhov zoo tshwj xeeb:
Obstacle tswj
Ntau cov khoom ntim khoom noj uas hloov tau yooj yim muab kev tiv thaiv zoo dua rau cov pa oxygen thiab noo noo ntau dua li cov ntim nyuaj. Qhov no yog qhov tseem ceeb vim tias lub neej txee feem ntau yog teeb meem teeb meem, tsis yog qhov teeb meem ntawm daim ntawv qhia. Yog tias oxidation lossis dej pauv yog koj tus yeeb ncuab thib ib, cov teeb meem zoo dua tuaj yeem txuas ntxiv lub neej txee ntawm ntim khoom noj yam tsis hloov cov khoom xyaw.
foob kev ua haujlwm
Hauv kev faib tawm tiag tiag, kev sib khi thiab cov ntaub ntawv tseem ceeb sib npaug. Txawm tias nyias zaj duab xis uas tsis muaj zog sealing yuav ua tsis tau. Lub ntim ntim tau yooj yim tuaj yeem tsim nyob ib puag ncig lub qhov rais kaw ruaj khov (tseem ceeb rau siab - cov kab ntim ceev), yog li txo cov xau thiab pov tseg.
Distribution durability
Cov hnab ntim tau yooj yim tuaj yeem tiv thaiv kev vibrations, tee, compression, thiab txias saw stacking, yog li txo kev puas tsuaj. Qhov no yog ib qho ntsiag to tab sis tseem ceeb pov tseg reducer.
Re sealing thiab 'tag nrho siv' tus cwj pwm
Cov khib nyiab hauv tsev feem ntau tshwm tom qab qhib. Kev ua haujlwm rov ua dua tshiab (zipper, slider, dej qhov hluav taws xob) thiab txhim kho kev faib khoom tau txo qhov teeb meem ntawm "tsis nco qab tom qab qhib ib zaug" - tshwj xeeb tshaj yog rau cov khoom noj txom ncauj, cheese, hmoov, khoom noj khov, thiab kua ntses.
Kev sib txuas ntawm carbon
Cov khoom pov tseg tsis yog ib qho teeb meem khib nyiab xwb; Nws yog emission multiplier. Cov pa roj carbon emissions los ntawm cov zaub mov pov tseg suav nrog txhua yam khoom siv los tsim cov zaub mov - dej, chiv, lub zog, tub yees, thiab kev thauj mus los. Thaum ntim khoom tiv thaiv kev lwj, nws kuj txo tag nrho cov emissions pov tseg.
Kev ntim khoom yooj yim tuaj yeem txo qis emissions hauv ob txoj hauv kev ib txhij:
Ua ntej, nws tiv thaiv zaub mov los ntawm kev muab pov tseg los ntawm kev txhim kho nws txoj kev tiv thaiv thiab txee lub neej.
Qhov thib ob, kev ntim khoom yooj yim feem ntau yog hnav thiab ua haujlwm zoo rau kev thauj mus los, uas tuaj yeem txo qis kev thauj mus los.
Qhov no yog qhov tseem ceeb heev rau cov tuam txhab lag luam: qhov kev daws teeb meem zoo tshaj plaws yog ib qho uas txo cov khoom pov tseg tag nrho, tsis yog ib qho uas zoo nkaus li yooj yim heev.

| Kas fes, tshuaj yej, txuj lom | Siab- lub hnab thaiv (feem ntau nrog cov yam ntxwv zoo li yooj yim-qhib thiab muaj zog reseal) | Tiv thaiv aroma thiab nres ya raws / oxygen puas tsuaj |
| Hmoov (mis nyuj, protein, sib tov) | Moisture-cov hnab tiv thaiv nrog cov tshuaj ntxuav kom huv | Txo cov clumping thiab kis kab mob tom qab qhib |
| Sauces, condiments | Spouted hnab | Tswj dispensing thiab reseal txo cov seem thiab mess |
| Cov khoom noj khov | Lub hnab ntim tau yooj yim rau ntim khoom noj khov | Txo lub freezer hlawv, punctures, thiab rov ua dua - qhib khib nyiab |
| Cov proteins tshiab (nqaij / nqaij nruab deg) | Lub tshuab nqus tsev los yog siab -barrier flexible structures (khoom-dependent) | Oxygen tswj thiab foob kev ncaj ncees txo qhov spoilage thiab xau |
| Npaj zaub mov | Thaum tshav kub kub- muaj peev xwm hloov tau cov qauv (qhov twg siv tau) | Txhim kho kev nyab xeeb thiab ruaj khov; txo qhov txias - saw khib nyiab hauv qee kis |
Cov ntsiab lus
Kev ntim khoom yooj yim tsis yog kev hloov pauv ntawm hom - nws yog lub tswv yim los txo cov khoom pov tseg.
Rau cov tuam txhab, qhov laj thawj muaj zog tshaj plaws los siv cov khoom ntim khoom noj yooj yim yog yooj yim: nws pab koj tswj cov tsav tsheb loj tshaj plaws - oxygen, av noo, kev puas tsuaj, thiab tshiab tom qab qhib. Rau cov neeg siv khoom, qhov tseem ceeb ntawm kev siv tau: ntim tau zoo dua thiab tiv thaiv cov khoom noj rau lub sijhawm ntev, txo cov khoom lwj thiab cov khoom pov tseg.
Thaum xaiv kom raug, cov khoom ntim khoom noj tau yooj yim tuaj yeem tiv thaiv cov khoom pov tseg thiab txhim kho kev thauj mus los, ua kom lub neej ntev ntawm cov ntim khoom noj, txo cov khoom poob, thiab txo qis carbon emissions.
