Mfundo Yogwira Ntchito ya Freeze Dryer & Freeze Drying Technology

Kuyanika ndi ukadaulo wapamwamba, wotsogola komanso wodalirika wochepetsera-katswiri wowumitsa vacuum sublimation, womwe umapangidwa mwapadera ndikugwiritsidwa ntchito mofala-kukonza mwakuya kwazakudya ndi zinthu zaulimi. Njira yonse yowumitsa m'mawu owumitsidwa amamaliza m'malo otsika kwambiri-kutentha komanso{4}}apamwamba, omwe ndi osiyana kwambiri ndi umisiri wakale-woumitsa kutentha kwambiri. Njira yonse yogwirira ntchito yagawika mwasayansi mu magawo awiri opitilira: -kuzizira kozizira ndi kuyanika kwa vacuum sublimation. Munthawi yaukadaulo isanakwane{9}kuzizira, chowumitsira chowumitsa mufiriji chimagwiritsa ntchito njira yabwino-yozizira yotentha kuti iwunikire mwachangu komanso molingana chinyontho chamkati cha chakudya ndi zopangira zaulimi kukhala miyala ya ayezi yowoneka bwino komanso yofanana mu nthawi yochepa. Njirayi imatha kukonza mawonekedwe apachiyambi, mawonekedwe a minofu ndi mawonekedwe a morphological azinthu, kuteteza kusinthika kwazinthu, kugwa kwa minofu ndi kuwonongeka kwamapangidwe panthawi yowumitsa wotsatira. Mkati mwa core vacuum sublimation stage,{13}}yomwe imagwira ntchito kwambiri imachepetsa mphamvu ya mpweya m'kati mwa chipangizocho kuti chizipanga malo osasunthika{14}}wopanda kanthu. Pansi kwapadera-kutentha ndi kutsika{17}}kupanikizika kwambiri, madzi oundana olimba m'kati mwa zinthuzo amasunthika kukhala nthunzi wamadzi popanda kusungunuka m'madzi amadzimadzi, ndipo nthunzi wamadzi umatuluka msanga m'zidawu kudzera mu exhaust system kuti amalize kuthira madzi m'thupi. Kuyanika konseko sikuphatikiza{19}}kutenthetsa kutentha kwakukulu, kupeweratu mavuto onse owonongeka ndi matenthedwe monga kuwonongeka kwa zakudya, kusinthasintha kwa kukoma, kuchepa kwa minofu ndi kuwonongeka kwa mtundu chifukwa cha kutentha{20}}kwambiri. Imatha kukhalabe ndi mawonekedwe atsopano, mawonekedwe achilengedwe, kukoma koyambirira komanso zakudya zonse zazakudya zosaphika ndi zaulimi, chomwe ndi chifukwa chachikulu chomwe umisiri wowumitsa amawumitsidwa amadziwika kuti ndiyo njira yabwino kwambiri yopangira{22}zakudya zomaliza ndi zaulimi.
