Raws li tus kws tshaj lij kev lag luam dej khov qhuav, kuv tau nug ntau zaus txog qhov ntev ntawm cov dej khov qhuav qhuav, tshwj xeeb tshaj yog qhov loj 1 lb. Kev nkag siab ntev npaum li cas cov dej khov qhuav yog qhov tseem ceeb txawm tias koj siv nws rau kev khaws zaub mov, kev xa mus kho mob, tshwj xeeb, lossis kev siv hauv kev lag luam. Hauv phau ntawv qhia dav dav no, peb yuav tshawb xyuas cov xwm txheej cuam tshuam rau cov dej khov nab kuab qhuav sublimation tus nqi, kev khaws cia kom raug.
Nkag siab txog cov dej khov qhuav Sublimation
Cov dej khov qhuav, cov khoom siv carbon dioxide (CO₂), tsis yaj zoo li cov dej khov li niaj zaus tab sis hloov mus rau sublimation - hloov ncaj qha los ntawm cov khoom mus rau roj ntawm -78.5℃(-109.3℃F) nyob rau hauv ib txwm atmospheric siab. Cov cuab yeej tshwj xeeb no ua rau nws muaj txiaj ntsig rau cov ntawv thov txias tab sis kuj txhais tau tias nws ploj mus dhau lub sijhawm yam tsis muaj cov kua dej seem.
Rau 1 lb block ntawm cov dej khov qhuav (kwv yees li 0.45 kg), lub sijhawm nws kav ntev yog nyob ntawm:
- Environmental kub
- Cia tej yam kev mob
- Tshaj tawm rau huab cua
- Daim ntawv ntawm cov dej khov qhuav (thaiv, pellet, lossis hmoov)
Duration kwv yees rau 1 lb qhuav Ice Block
Raws li kev paub dhau los ntawm kev lag luam thiab kev tshawb fawb, ntawm no yog lub sijhawm ntev npaum li cas koj tuaj yeem cia siab tias 1 lb qhuav dej khov yuav kav ntev npaum li cas:
1. Chav ntsuas kub (qhov phem tshaj - xwm txheej)
- Qhib lub thawv / lub rooj zaum saum toj: Kwv yees li 5 feeb kom tiav sublimation
- Uninsulated nto: Txog 2-3 teev rau tag nrho sublimation
2. Basic Insulated Containers
- Styrofoam txias nrog lub hau: 18-24 teev
- Kev ntim khoom kom zoo nrog cov txheej txheem rwb thaiv tsev: Txog 24-36 teev
3. Kev Kho Kom Zoo Tshaj Plaws
- Lub freezer qhuav tshwj xeeb: 5-10 hnub
- Kev lag luam qhuav dej khov chav tsev: Muaj peev xwm mus txog 2 lub lis piam
Nco tseg: Cov no yog qhov kwv yees dav dav - lub sijhawm tiag tiag txawv raws li cov xwm txheej tshwj xeeb.
Yam tseem ceeb cuam tshuam rau cov dej khov qhuav kom ntev
1. Cia kub
Lub ambient kub dramatically cuam tshuam tus nqi sublimation. Rau txhua txhua 10℃nce nyob rau hauv ambient kub, sublimation tus nqi kwv yees li ob npaug. Qhov no piav qhia vim li cas:
Chav ntsuas kub (20-25 degree): ceev sublimation (teev)
Txias hauv qab daus (15 degree): Nruab nrab sublimation (12-24 teev)
Txias ib puag ncig (4 degree): qeeb sublimation (hnub)
Lub freezer tshwj xeeb (-80 degree): Tsawg sublimation (lub lis piam)
2. Rwb thaiv tsev zoo
Kev rwb thaiv tsev kom zoo yog txoj hauv kev zoo tshaj plaws los txuas ntxiv lub neej dej khov qhuav rau cov neeg siv feem ntau. High-cov thawv ntim ua npuas ncauj tshwj xeeb tsim rau cov dej khov qhuav tuaj yeem ua kom lub neej ntev li 5-10 npaug piv rau cov cua txias.
Cov kev daws teeb meem muaj xws li:
- Muab ob npaug rau- cov thawv ntim ua npuas ncauj: 24+ teev
- Nqus -insulated ntim: 48+ teev
- Theem -hloov cov ntim khoom: 72+ teev rau cov khoom xa tuaj
3. Huab cua
Kev sib pauv huab cua tsawg kawg yog qhov tseem ceeb vim tias:
- CO₂ gas accumululation slows ntxiv sublimation
- Tsawg sab nraum cua sov nkag mus rau hauv lub thawv
- Qhov chaw txias yog khaws cia ntev dua
Txawm li cas los xij, ua kom tiav airtight sealing yog qhov txaus ntshai vim yog lub zog tsim los ntawm subliming CO₂ - ib txwm tso cai rau qee qhov tso pa tawm.
4. Thaiv qhov loj thiab zoo li
Ib qho 1 lb block yuav kav ntev dua qhov hnyav tib yam hauv pellets lossis hmoov vim:
- Qhov chaw qis dua rau qhov ntim piv
- Tsawg ncaj qha raug rau huab cua sov
- Ntau pawg khaws cia txias ntev dua
Qhov no yog qhov twgqhuav ice pelletizersua qhov tseem ceeb - cov tshuab no compress cov dej khov qhuav rau hauv cov pellets lossis cov blocks. Pelletized qhuav dej khov muaj cov yam ntxwv sib txawv ntawm sublimation vim qhov nce ntawm qhov chaw, ua rau nws zoo tagnrho rau qee yam kev siv xws li ntxuav lossis txias txias qhov twg sai sublimation yog qhov xav tau.
Tswv yim tswv yim kom ua kom koj 1 lb qhuav Ice Block lub neej
1. Ua ntej- txias koj lub thawv: Muab lub qhov txias txias tso rau hauv lub tub yees rau ib teev ua ntej ntxiv dej khov qhuav
2. Siv cov khoom ntim kom zoo:
- Hauv qab txheej: ntawv xov xwm lossis duab los qhia
- Nruab Nrab: Cov dej khov qhuav qhwv hauv cov ntawv xov xwm (tsis nruj)
- Sab saum toj: Lwm txheej ntawm cardboard los yog rwb thaiv tsev
3. Txo qhov qhib: Txhua zaus koj qhib lub thawv, huab cua sov nkag
4. Khaws rau hauv qhov chaw txias tshaj plaws: Cov hauv qab daus ua haujlwm zoo tshaj qhov chaw nres tsheb lossis tsheb
5. Xav txog kev faib cov block: Yog tias koj tsis xav tau lub zog txias tag nrho tam sim ntawd, txiav tawm cov khoom raws li xav tau
Xaus: Ua Koj 1 lb Qhuav Ice Block Kawg
Txhawm rau txiav txim siab ntev npaum li cas 1 lb cov dej khov qhuav yuav kav ntev:
- Qhov phem tshaj (qhib cua): 5 feeb mus rau 3 teev
- Lub caij txias txias: 18-24 teev
- Optimized cia: 24-36 teev
- Professional lub freezer: 5-10 hnub
Los ntawm kev nkag siab txog cov xwm txheej cuam tshuam rau sublimation thiab siv cov txheej txheem cia kom zoo, koj tuaj yeem npaj koj cov dej khov qhuav qhuav thiab ua kom nws muaj txiaj ntsig rau koj cov kev xav tau tshwj xeeb.
Txawm hais tias koj tab tom tsim kev ua yeeb yam pos huab, xa cov khoom tsis zoo, lossis ua cov kev sim tshawb fawb, kev tswj dej khov kom zoo ua kom muaj txiaj ntsig thiab kev nyab xeeb. Nco ntsoov sab laj nrog koj tus neeg muag khoom dej khov qhuav rau cov lus pom zoo tshwj xeeb uas haum rau koj cov xwm txheej hauv zos thiab npaj siv.
