Yuav ua li cas kom khov qhuav txiv hmab txiv ntoo ua haujlwm

Nkoog qhuav lossis khov Lyophiliat tshem tawm cov dej noo los ntawm cov khoom lag luam nyoos lossis khov ntawm lub tshuab nqus tsev, txheej txheem hu ua sublimation. Qhov kev tshwm sim hauv kev huv si, wholesome, zaub mov muaj txiaj ntsig zoo, ua zaub mov ntev, ua zaub mov thiab yooj yim. Nkoog-kom qhuav ua haujlwm los ntawm kev txiav cov khoom khov lossis tso lawv rau ntawm cov tais uas tau muab khaws cia thiab muab khaws cia hauv lub freezer. 

Cov khoom lag luam yog khov ntawm txawm khov txias kub txog thaum lawv ncav tes ua qhov zoo tshaj plaws hauv uas cov khoom qub ntawm cov khoom tuaj yeem tswj tau. Lub voj voog thiab tshuab ziab khaub ncaws hloov kom rov ua kom sov thiab nqis los ua dua cov sublimation, tshem dej ntawm cov zaub mov. 

Khov yog paub tias muaj tshwm sim thaum cov khoom noj muaj nyob hauv lub freezer ntev, thiab cov khoom noj qhuav heev tau khov rau ntev ntev, txawm tias nws tau khaws cia hauv lub freezer ntev ntev. 

Thaum lub tshuab ua zaub mov txias, lub tshuab ziab khaub ncaws khov ua qhov kub uas ua rau cov dej kom yaj. Thaum cov zaub mov qhuav tag, nws yog ntim los tiv thaiv kom tiv thaiv kom muaj noo noo los ntawm kev sib sau thiab spoiling. Qee tus neeg, zoo li tus ntawm no, tseem thov kom siv lawv lub freezer kom khov-qhuav. 

Qhov twg txoj kev siv, cov lus zais ntawm khov yog cov khoom noj tau qhuav los ntawm kev hloov cov roj muaj roj rau hauv cov roj-roj. 

Thaum koj npaj txhij siv cov zaub mov, qhib cov dej sov thiab ntxiv rau kom txog thaum nws tau mus txog nws qhov sib txawv, txog 2 - 3 teev. 

Cov txheej txheem no yog hu ua sublimation thiab cais los ntawm khov-qhuav, qhov twg cov zaub mov tsuas khov hauv lub hnab ntim lossis, yog tias koj tau siv rau hauv ib lub taub ntim. Nco ntsoov tias cov txheej txheem ziab yuav siv sijhawm li ib lub lim tiam. Txoj hauv kev zoo tshaj plaws los tshawb xyuas thaum koj cov zaub mov qhuav yog kom tshem cov khov thiab cia lawv tuaj rau chav sov. Cov zaub mov pib khov ua kom khov hauv thawj ob peb teev tom qab khov, tab sis tsis yog rau ntau tshaj ob peb hnub. 

Thaum cov zaub mov hloov dub dub, qhov no txhais tau tias kev ziab txheej txheem tseem tsis tau ua tiav, tab sis nws dries. Koj tuaj yeem ua tiav txog 1,000 phaus ntawmFreszen txiv hmab txiv ntooIb hnub, ib hnub ntau uas ib txwm nyob rau 1/2 txog 10 poom, yog li nws yooj yim rau kev pom. 

Ib qho kev tshawb fawb nthuav dav txog dej yog tias nws tsis tuaj yeem muaj nyob hauv kua lossis lub tshuab nqus tsev, tab sis nws muaj raws li lub suab-lub xeev. 

Tom qab lub tshuab tau rhaub cov zaub mov khov maj mam, kom cov zaub mov tseem nyob hauv nws lub xeev qub, yog li cov zaub mov tseem nyob hauv daim ntawv ntawm cov xim, saj thiab txhua yam. Cov khoom noj uas khov-qhuav tuaj yeem npaj tau yooj yim rau kev noj los ntawm kev ntxiv dej rau kev kub siab rau cov dej rov qab. 

Txawm nyob rau hauv chav tsev kub, khov-qhuav cov khoom muaj lub neej ntev dua thiab khaws lawv cov xim qub thiab tsw thaum qhuav. Qhov tseeb, cov zaub mov feem ntau, cov nqaij nyoos lossis siav siav, tuaj yeem ua kom tau cov khoom lag luam, tsim khoom lag luam uas zoo, yog tias tsis zoo dua, ntau dua li lawv cov tshuaj nyoos. 

Yog li, rau hnub tim, lub peev xwm loj heev ntawm khov - kom qhuav - tsis tau siv tag nrho, tab sis rau ntau tus neeg, nws tseem muaj kev xaiv zoo. 

Muaj txheej txheem hu ua sublimation, ib tug me me - paub tab sis tseem ceeb txheej txheem uas tso cai rau ziab. Cov neeg feem coob tsis mus rau hauv lub khw muag khoom noj lossis txawm tias lub Hoobkas khoom noj khoom haus kom pom kev hloov pauv, tab sis qhov chaw dej tsis muaj zog thiab dries, tsim nyog siv sijhawm me me hauv lub tsom teeb. Yog tsis muaj kev pab ntawm sublimation, txheej txheem khov-kom qhuav-kom qhuav yuav tsis tau muaj. Nws ua cov khoom lag luam zoo dua uas khaws nws cov zaub mov muaj txiaj ntsig thaum nws khov. 

Ib qho ntxiv, cov tshuab ziab khov muaj qhov rov ua dua siab dua piv rau lwm cov khoom qhuav. Cov txheej txheem Sublimation, txhawb nqa los ntawm kev sib xyaw ntawm cov dej vapor, carbon dioxide, nitrogen thiab oxygen thiab oxygen, muaj txiaj ntsig zoo hauv cov khoom thiab nws cov khoom noj muaj txiaj ntsig. Peb saib seb kev tshawb fawb science rau cov txheej txheem thiab sim vaporize nws kom nws phim dab tsi uas peb paub. 

Quav kom qhuav tuaj yeem siv ntau yam khoom noj, los ntawm cov txiv hmab txiv ntoo thiab zaub rau nqaij, cov khoom noj siv mis thiab cov nqaij. 

Mercer cov khoom noj muaj cov txheej txheem sublimation nyob rau hauv ib puag ncig kev hloov pauv uas ua rau cov dej khov kho los ntawm cov dej khov rau hauv dej khov, tawm ntawm cov txiv hmab txiv ntoo qhuav. Nkoog-kom qhuav kom tshem tawm cov dej khov los ntawm cov khoom noj khov, tawm ntawm cov khoom noj zoo kawg nkaus tom qab. Nws kuj tseem mob melting ntawm cov txiv hmab txiv ntoo khov thiab zaub, ib qho laj thawj ua rau muaj cov zaub mov lom hauv Asmeskas. 

Nws yuav siv ntau yam kev txawj thiab kev paub dhau los ua kom zoo dua cov txheej txheem khov - kom qhuav hauv chav nqus tsev. Qhov no muaj xws li cov zaub mov txias txias, tshem yuav luag txhua yam kev ya noo hauv lub tshuab nqus tsev thiab thaum kawg sib khi nws hauv lub dav hlau airtight. Cov khoom noj khov-qhuav tuaj yeem khaws cia rau lub sijhawm ntev, tau thauj khoom yooj yim rau ntawm qhov kub thiab noj nrog qhov tsawg kawg nkaus kev npaj. Qhov no yuav tsum tau txais nws txoj cai thiab tsis txhob muaj kev pheej hmoo ntawm cov zaub mov tau hlawv lossis lwm yam puas tsuaj.
