Freeze dryer, lyophilizer, vacuum freeze dryer (sh) hka lim ai jak ngu nna mung tsun ai, hka lim ai jak -hkum tsup ai malu masha arung arai ni a matu sha laksan hka lim ai jak re. Shi a core hpaji masa gaw freeze-hkyet ai (lyophilization) gaw oven hta hkyet ai, jan hta hkyet ai hte nbung katsi ai hta hka n-gun yawm ai hte tsep kawp shai ai.
Lab chyam dinglik na matu bench-top freeze dryer (sh) law law galaw shapraw na matu industrial freeze dryer rai tim, hka lim ai hte hka lim ai bungli yawng hpe n-gun n rawng ai matut mahkai lam masum hku garan nna galaw ai: hka lim ai shawng na hka lim ai, shawng nnan na sublimation hka lim ai hte lahkawng ngu na desorption hka lim ai.
Pre-freezing stage hta, freeze drying jak gaw, namsi namsaw ni hte shan nnan ni a kata na manu jahpu n jaw ra ai hka hpe, n-gun n law ai shara hta, hka lim hkra lawan ladan hka lim kau ya ai. Hkum tsup ai pre-freezing gaw, hka n-gun rawng ai hka gaw malu masha a fiber tissue hpe n-gun n rawng hkra pat shingdang ya ai, dai gaw -quality kaja ai lyophilization galaw ngut sai arung arai ni a matu ra kadawn ai lam rai nga ai.
Dai majaw, n-gun rawng ai hka lim ai jak a core bungli galaw ai lam gaw, npawt nhpang sublimation hka lim ai lam rai nga ai. Hkap pat da ai high-vacuum makau grup yin npu hta, malu masha raw materials kata na solid ice gaw hka n-gun de hkrak sha sublime galaw nna, hka n-gun hpe shapraw kau ai. Industrial lyophilizer gaw grau n-gun ja ai pumping atsam nga ai rai nna, n-gun ja ai mass freeze-htum mat hkra galaw lu ai.
Secondary desorption drying gaw malu masha n-gun hta rawng ai ngam nga ai hka hpe shapraw kau ya ai. Freeze dryer a hkrak tup ai nbung katsi ai hpe hkang ai ladat gaw, katsi ai hpe grau kaja hkra, freeze-katsi ai namsi namsaw ni, shan hte dumsu malu masha ni hpe n-gun jaw na matu, arung arai ni hpe loi loi hte katsi shangun ai. Bench-ntsa kaw na hka lim ai jak gaw kaji kajaw sample parameter ni hpe atsawm sha gram lajang na matu kaja ai.
Hpang jahtum tsun ga nga yang, freeze dryer hte lyophilizer a shingjawng ai lam a madung akyu gaw, n-gun n law ai -n-gun n law ai vacuum hka n-gun yawm mat ai lam hta rai nga ai. Freeze-drying hte lyophilization gaw shingra tara hku nna n-gun dat ni hte malu masha a npawt nhpang nsam hpe n-gun jaw ya ai majaw, ndai hpaji masa gaw mungkan ting na high-end namsi namsaw, shan hte dumsu malu masha galaw shapraw ai hpaga lam ni hpe uphkang nga ai.
