Vacuum freeze kuyanika ndi njira yochepetsera madzi m'thupi potengera mfundo ya ice crystal sublimation, yomwe ndi yosiyana kwambiri ndi njira zanthawi zonse zochepetsera madzi m'thupi mwaukadaulo. Ntchito yonseyi imachitika motsekedwa kwambiri-kutentha kochepa komanso{2}}pamalo opanda mpweya. Kudzera{4}}kuletsa kuzizira kotheratu, madzi aulere mkati mwa zinthuzo amaunjidwa kukhala timiyala tating'ono ting'ono ta ayezi, kutseka malo oyamba komanso mmene zinthuzo zimakhalira.
Mu vacuum sublimation siteji, makhiristo oundana amkati mwazinthuzo amasinthidwa mwachindunji kukhala nthunzi yamadzi ndikutulutsidwa popanda kusungunuka, kumayenda komanso kusamuka kwamadzi amadzimadzi. Palibe extrusion, mapindikidwe kapena structural kuwonongeka kwa minofu zakuthupi pa ndondomeko yonseyi. Makina apadera opangira zinthuwa amatsimikizira kuti mtundu wachilengedwe, kukoma koyambirira, ulusi wazakudya, mapuloteni ogwira ntchito komanso zosakaniza zogwira ntchito zazinthuzo zimasungidwa mokwanira, ndikuzindikira "kukoma koyambirira ndi mtundu woyambirira" kukonza.
Pakutha kwa malonda, kuzizira-zouma zimakhala ndi mawonekedwe apamwamba osasinthika-. Maonekedwe onenepa komanso athunthu amapewa kuchepa kwa zinthu ndi mapindikidwe. Dongosolo lotayirira lamkati limabweretsa magwiridwe antchito abwino kwambiri a rehydration, omwe amatha kubwezeretsanso zinthu zatsopano pambuyo pobwezeretsa madzi m'thupi. Chinyezi chotsalira chochepa chimalepheretsa kukula kwa mabakiteriya ndi nkhungu, zomwe zimapangitsa kuti zinthuzo zikhale zokhazikika bwino zosungirako komanso kusinthasintha kwa kayendedwe.
Makina athu a CE- ovomerezeka a mafakitale owumitsa amazindikira-njira zonse zanzeru komanso zowongolera zowumitsa{2}}zouma. Kukwera kwa kutentha kwagawidwe ndi kachitidwe ka vacuum reguum kungagwirizane ndi mawonekedwe a zinthu zosiyanasiyana, kusintha moyenera-kuzizira kozizira, kutentha kwa sublimation ndi digiri ya vacuum yogwirira ntchito, ndikupanga masikimu okonzekera zinthu zosiyanasiyana. Dongosolo lonse-lowunika ndikujambulitsa data limaonetsetsa kuti zinthu zitha kutsatidwa bwino komanso zomwe zingabwerezedwe popanga zinthu, zikukwaniritsa-zofunikira pakuwongolera kwabwino kwambiri pakukonza kwamakono kwa mafakitale.
M'mafakitale, umisiri wowumitsa wa vacuum freeze umayang'ana kwambiri-zolondola,{1}}zapamwamba-zapamwamba komanso zapamwamba-zosunga malo, ndipo zimagwira ntchito pamitundu yonse ya -zotentha kwambiri-zinthu zovutirapo zomwe zimafunika kusunga zosakaniza zomwe zimagwira ntchito komanso mawonekedwe ake enieni. Ndi kupititsa patsogolo miyezo yaupangiri wamsika, zida zowumitsa zowumitsa zokhazikika komanso zanzeru zakhala chida chofunikira kwambiri pantchito yaukadaulo-yapamwamba kwambiri, yopereka chithandizo chokhazikika kwa mabizinesi kuti apange{7}}zinthu zosiyanitsidwa bwino kwambiri.
