Kodi Chowumitsira Chozizira Chimagwira Ntchito Bwanji?

Choumitsira mufiriji (lyophilizer) ndi ukadaulo womwe umagwiritsa ntchito mfundo ya sublimation poumitsa. Njirayi imaphatikizapo kuzizira mofulumira chinthucho kuti chiume pa kutentha kochepa, kenako, pansi pa malo oyenera otayira mpweya, zomwe zimapangitsa kuti mamolekyu a madzi oundana alowe mwachindunji mu nthunzi ya madzi ndikutuluka. Chopangidwacho chomwe chimapezeka poumitsa mufiriji chimatchedwa lyophilisate, Njirayi imatchedwa lyophilization.

Musanaumitse, chinthucho chimakhalabe pa kutentha kochepa (mkhalidwe wozizira), ndipo makhiristo a ayezi amagawidwa mofanana mkati mwa chinthucho. Pa nthawi ya sublimation, palibe kuchuluka komwe kumachitika chifukwa cha kusowa madzi m'thupi, motero kupewa zotsatirapo zoyipa monga thovu kapena okosijeni zomwe zimachitika chifukwa cha nthunzi ya madzi. Zinthu zouma zimawoneka ngati siponji youma, yokhala ndi mapopoma, yopanda kusintha kwa voliyumu, ndipo zimasungunuka kwambiri m'madzi, ndikubwerera mosavuta momwe zinalili poyamba. Njirayi imaletsa kwambiri kuwonongeka kwa zinthu zouma, mankhwala, komanso zachilengedwe.

Chowumitsira chozizira chimakhala ndi makina oziziritsira, makina opumira mpweya, makina otenthetsera, ndi makina owongolera zida zamagetsi. Zigawo zake zazikulu zimaphatikizapo chipinda chowumitsira mpweya, choziziritsira mpweya, chipinda choziziritsira mpweya, pampu yopumira mpweya, ndi chipangizo chotenthetsera/choziziritsira mpweya. Mfundo yogwirira ntchito ya chowumitsira mpweya chozizira ndikuyamba kuziziritsa zinthuzo kuti ziume pansi pa kutentha kwake kwa mapointi atatu, kenako, pansi pa vacuum, zimapangitsa kuti madzi olimba (ayezi) omwe ali mu chinthucho alowe mu nthunzi ya madzi, yomwe imachotsedwa mu chinthucho, motero imauma. Pambuyo pokonza, zinthuzo zimatumizidwa ku chipinda chozizira mwachangu kuti ziume, kenako ku chipinda chowumitsira mpweya kuti ziume, ndipo pamapeto pake zimayikidwa mu workshop yokonzekera pambuyo pokonza. Dongosolo la vacuum limakhazikitsa malo otsika mphamvu mu chipinda chowumitsira mpweya, makina otenthetsera amapereka kutentha kobisika kwa sublimation ku chinthucho, ndipo makina oziziritsira amapereka mphamvu yoziziritsira yofunikira ku chipinda chozizira ndi chowumitsira mpweya.

Zipangizozi zimagwiritsa ntchito kutentha kwa radiation, kuonetsetsa kuti kutentha kumafalikira mofanana; zimagwiritsa ntchito msampha wozizira womwe umathandiza kuti madzi asungunuke mwachangu; zimagwiritsa ntchito chipangizo chopopera mpweya chokhala ndi mphamvu yolekanitsa mafuta ndi madzi; zimagwiritsa ntchito njira yoziziritsira yomwe imapereka kuziziritsa kwa ma circuits angapo nthawi iliyonse, kuonetsetsa kuti zinthu zikuyenda bwino komanso kuti mphamvu zigwire bwino ntchito; zili ndi luntha lochita kupanga, zomwe zimapangitsa kuti zinthu ziziyenda bwino komanso kuti zikhale zosavuta kugwiritsa ntchito.

Zofunikira pa khalidwe la zinthu zouma mufiriji ndi izi: ntchito yosasinthika ya zamoyo, mawonekedwe ndi mtundu wofanana, mawonekedwe okhuthala, kapangidwe kolimba, kuchuluka kwa kusungunuka mwachangu, ndi chinyezi chochepa chotsalira. Kuti mupeze zinthu zabwino kwambiri, kumvetsetsa bwino chiphunzitso cha kuumitsa mufiriji ndi njira ndikofunikira. Njira yowumitsa mufiriji imaphatikizapo magawo atatu: kuzizira musanayambe, kuumitsa koyamba (sublimation), ndi kuumitsa kwachiwiri (desorption). Kufupikitsa nthawi youma mufiriji moyenera komanso moyenera kuli ndi phindu lalikulu pazachuma popanga mafakitale.

"Ngati mukufuna zouma mufiriji kapena mukufuna kudziwa zambiri za zinthu ndi ntchito zathu, chonde musazengereze kutero."Lumikizanani nafe. Tikusangalala kukupatsani upangiri ndikuyankha mafunso aliwonse omwe mungakhale nawo. Gulu lathu likuyembekezera kukutumikirani ndikugwira nanu ntchito mtsogolo!
