Kuomesa nechando kunoshanda pamusimboti we sublimating solvents kubva kune yakasimba samples yakananga mugasi mune vacuum, ichiwana kuomeswa. Sezvo ichiomesa sampuli patembiricha yekamuri kana pasi, inochengetedza chiitiko chavo chebhaibheri, ichivapa porous uye kunyungudika nyore. Nekudaro, kuomesa-kuomesa inzira yakanakisa yekuchengetedza bioactive samples.
Maitiro Okushanda eFreeze Dryer:
一. Pre-freezing Kugadzirira:
1.Isa zvinhu zvakaenzana pane tireyi yezvinhu, kuve nechokwadi kuti ukobvu husingapfuuri 10mm. Isa iyo tembiricha yemagetsi sensor nenzira kwayo mukati mechinhu uye ichengetedze.
2.Isa tireyi ine zvinhu pane chando-kuomeswa rack, wozopinda mumusungo unotonhora, uye uvhare nevhavha yekuvhara.
3.Batidza simba guru rekushandura. Kana uchironga kuunza nitrogen (kana imwe gasi inert) mukamuri yekuomesa pakupera kwekuomesa nechando, tanga washandisa nitrogen kuchenesa mvura inopinza, wozovhara vharafu yemvura.
二. Material Pre-freezing
Material pre-freezing inhanho yakakosha mukuomesa-kuomesa, inokanganisa zvakananga kunaka kwechigadzirwa chakaomeswa nechando. Pre-freezing inogona kuitwa kuburikidza nechando chinononoka kana kukurumidza kutonhora, zvichienderana nezvinodiwa chaizvo. Semuyenzaniso:
1.Slow Freezing: Isa zvinhu zvakagadzirirwa mumusungo unotonhora, uvhare nevhavha yekuvhara, uye tanga compressor. Pre-freezing inotanga.
Kurumidza Kutonhora: Tanga iyo compressor kutanga. Pane imwe nguva tembiricha mu
2. inotonhora musungo kamuri inodonha kune imwe nhanho, isa zvinhu zvakagadzirirwa mumusungo unotonhora. Pre-freezing inotanga.
三. Kuomesa nechando:
1.Bvisa rack yezvinyorwa kubva muimba inotonhora yemusungo uye uiise pane imwe nzvimbo yakaoma yeplastiki disc (zvose zvakaiswa pamusoro pekamuri yechando inotonhora). Zvadaro vhara nekavha ye acrylic. Kana ukashandisa chifukidziro chekumanikidza kuomesa-kuomesa zvinhu, kurumidza kuendesa zvinhu kubva kune pre-chando rack kuenda kune tireyi yekumanikidza yekuvhara mudziyo, wobva wavhara nekavha yeacrylic.
2.Pachidzitiro chekushanda kwemidziyo, dzvanya bhatani re "Vacuum Pump" kuti utange pombi yekutsvaira. Dzvanya bhatani re "Vacuum Gauge" kuratidza iyo vacuum level. Kana iyo vacuum level yasvika yakatenderedza 30Pa, dzvanya bhatani re "Kupisa" kuti utange kuomesa-kuomesa maitiro, ayo anomhanya zvinoenderana neyakagadzikwa chirongwa chirongwa.
Cherechedza: Iyo vacuum gauge zero yakagadziriswa, saka vashandisi havafanire kuigadzirisa. Mushure mekubatidza geji yevacuum, kuverenga kwemuchadenga kwe110 × 103～80 × 103Pa kwakajairwa uye hakudi kugadziriswa. Kurudziro: Ingovhura iyo vacuum geji kana uchitarisa iyo vacuum level panguva yekuomesa-kuomesa. Ivhare kana isiri kushandiswa kuwedzera hupenyu hwayo.
四. Defrosting Operation:
1.Pachidzitiro chekushanda kwemidziyo, dzvanya bhatani re defrost kuti utange iyo inotonhora trap defrosting. Kamwe defrosting kwapera, sisitimu inozomisa maitiro. (Iri basa rinofanira kuwanikwa pamhando dzakasarudzwa.)
Chenesa aizi, unyoro, uye tsvina mukati memusungo unotonhora, uye chengetedza midziyo nemazvo. Mushure mekunge chando chiri mukamuri inotonhora yemuteyo yanyunguduka, inogona kudonhedzwa kunze kuburikidza nevhavha yemvura inopinza. Kana isiri kushandiswa, chengetedza vharafu yekupinza mvura yemuchina mukuru panzvimbo yakashama.
"Kana iwe uchifarira kugadzira chikafu chakaomeswa nechando kana uchida kudzidza zvakawanda nezve zvigadzirwa nemasevhisi edu, ndapota sunungukataura nesu. Isu tinofara kukupa mazano uye kupindura chero mibvunzo yaungave uine. Boka redu richafara kukushandira. Tarisira kutaurirana nekushandira pamwe newe!"
