Tshawb nrhiav keeb kwm ntxim nyiam thiab cov txheej txheem hloov pauv tom qab khov-qhuav khoom qab zib, ib txoj hauv kev khaws cov zaub mov los ntawm kev tshem tawm nws cov ntsiab lus dej. General Foods Corporation pioneered no innovation nyob rau hauv 1964. Cia peb delve rau hauv yuav ua li cas khov-drying ua hauj lwm, nws cov txiaj ntsig hauv kev khaws cov saj, kev ntxhib los mos, thiab khoom noj muaj txiaj ntsig, thiab nws siv dav hauv txiv hmab txiv ntoo, zaub, nqaij, thiab khoom qab zib preservation.
Tshooj 1: Kev Tsim Kho Cov Khoom Qab Zib Khov Khov
Xyoo 1964, General Foods Corporation tau hloov pauv kev lag luam khoom noj khoom haus los ntawm kev qhia cov khoom qab zib khov-qhuav. Cov txheej txheem khaws cia no koom nrog tshem cov dej ntawm cov khoom noj, yog li khaws nws cov qauv qub thiab cov khoom noj tseem ceeb.
Kauj Ruam 2: Txoj Kev Kho Kom Qhuav Qhuav tau nthuav tawm
Cov txheej txheem khov-drying nthuav tawm los ntawm kev ua tib zoo orchestrated cov kauj ruam, kom ntseeg tau cov khoom qab zib cov yam ntxwv xav tau thiab txuas ntxiv nws lub txee lub neej. Cia peb tshawb xyuas txhua theem:
khov:Thaum xub thawj, cov khoom qab zib raug rau qhov kub qis qis qis dua -40 degree (-40 degree F), txo qis tus nqi degradation thiab tswj nws cov qauv thiab cov khoom noj muaj pes tsawg leeg.
Vacuum Chamber:Cov khoom qab zib khov yog tom qab ntawd muab tso rau hauv lub tshuab nqus tsev kaw, tsim kom muaj qhov chaw qis qis. Lub tshuab nqus tsev no negates qhov xav tau rau cov dej kom dhau los ntawm cov kua theem thaum lub sijhawm ziab.
Sublimation:Qhov kub nyob rau hauv lub chamber maj mam nce, ua rau cov dej khov hauv cov khoom qab zib mus rau sublimation. Sublimation yog hais txog kev hloov pauv ncaj qha ntawm dej los ntawm cov khoom mus rau cov roj yam tsis tau nkag mus rau theem ua kua.
Moisture Extraction:Raws li cov dej hloov mus rau hauv vapor, lub tshuab nqus tsev nqus tau zoo rub tawm ntawm lub chamber, tshem tawm feem ntau ntawm cov khoom qab zib cov dej noo. Cov kauj ruam no pab tiv thaiv kev loj hlob ntawm cov kab mob thiab lwm yam kab mob.
Superior Ntim:Thaum kawg, cov khoom qab zib khov-qhuav yog meticulously kaw nyob rau hauv noo noo-pov thawj ntim, tiv thaiv nws tiv thaiv reabsorption ntawm noo noo los ntawm ib puag ncig ib puag ncig. Cov txheej txheem sealing no tsis tsuas yog tswj cov khoom qab zib kom zoo nkauj tab sis kuj ua kom lub neej ntev ntev.
Ntu 3: Khaws cov saj, kev ntxhib los mos, thiab khoom noj muaj txiaj ntsig
Txoj kev khov-drying ci ci hauv kev khaws cov saj, kev ntxhib los mos, thiab kev noj haus zoo ntawm cov khoom qab zib. Los ntawm kev tshem cov dej thaum ua kom cov khoom tseem ceeb tsis zoo, cov khoom qab zib khov qhuav khaws nws cov khoom qub, cov xim zoo nkauj, thiab cov khoom zoo nkauj thaum rov ua dej. Tsis tas li ntawd, cov txheej txheem khaws cia no txo qis cov khoom noj khoom haus tsawg, ua rau cov neeg siv khoom txaus siab rau cov khoom qab zib nrog cov txiaj ntsig kev noj haus ntxiv.
Nrog rau kev tsim cov khoom qab zib khov-qhuav los ntawm General Foods Corporation hauv xyoo 1964, kev lag luam khoom noj khoom haus tau pom qhov kev khaws cia zoo kawg nkaus. Cov txheej txheem khov-drying, suav nrog kev khov, sublimation, tshem tawm cov dej noo, thiab kev ntim khoom zoo, tso cai rau kev khaws cia ntawm saj, kev ntxhib los mos, thiab khoom noj muaj txiaj ntsig. Cov txheej txheem no tseem tau txais txiaj ntsig, tsis yog rau cov khoom qab zib xwb tab sis kuj tseem khaws cia ntau yam khoom noj. Kawm paub txog qhov zoo siab thiab kav ntev ntawm cov khoom qab zib khov-dried, ua pov thawj rau qhov kev txawj ntse ntawm kev khaws zaub mov.
